Description

Technical Field

[0001] The present invention relates to the field of electrical equipment, and particularly to a vertically rotating indoor AC metal-enclosed switchgear. Background Art

[0002] As a common electrical equipment, the indoor AC metal-enclosed switchgear includes various electrical equipment inside. With the increasing changes in production requirements, whether it is for saving space or equipment costs, the miniaturization of equipment is an important trend. The existing indoor AC metal-enclosed switchgear has not effectively combined and unified the aspects of the main equipment being removable and miniaturization. The convenience, safety of equipment installation and maintenance, and the reliability of operation are not ideal, and it cannot meet the miniaturization and removable requirements of actual operation. Summary of the Invention

[0003] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a vertically rotating indoor AC metal-enclosed switchgear to achieve the purpose of miniaturization and removability of the vertically rotating indoor AC metal-enclosed switchgear.

[0004] The technical solution adopted by the present invention to solve its problems is as follows:

[0005] A vertically rotating indoor AC metal-enclosed switchgear includes a cabinet, and a contact box device, a shutter device, a vertically rotating isolating vacuum circuit breaker, an inductance device, and a driving component arranged in the cabinet from top to bottom.

[0006] The driving component acts on the vertically rotating isolating vacuum circuit breaker and the shutter device synchronously.

[0007] Wherein, the driving component drives the shutter device and the vertically rotating isolating vacuum circuit breaker to move. After the shutter device is fully opened and stopped, the vertically rotating isolating vacuum circuit breaker continues to move and passes through the shutter device to be respectively connected to the contact box device and the inductance device above and below. And, the driving component drives the shutter device and the vertically rotating isolating vacuum circuit breaker to move. After the vertically rotating isolating vacuum circuit breaker withdraws from the shutter device and is disconnected from the contact box device and the inductance device respectively, after the vertically rotating isolating vacuum circuit breaker moves and resets, the shutter device continues to move and is fully closed.

[0008] In summary, the vertically rotating indoor AC metal-enclosed switchgear provided by the present invention has the following technical effects:

[0009] By rotating the vertical isolation vacuum circuit breaker and the shutter for a partial stroke, that is, the vertical isolation vacuum circuit breaker and the shutter device share a driving component, the use of components is reduced, the space occupied by the cabinet is decreased, and the cabinet size is minimized. At the same time, the time point when the driven component of the shutter is driven is earlier than the end of the vertical isolation vacuum circuit breaker or later than the execution of the vertical isolation vacuum circuit breaker. In this way, the movement stroke of the shutter is shortened, the space requirement of the shutter in the cabinet is reduced, and the miniaturization of the vertical indoor AC metal-enclosed switchgear is achieved.

[0047] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0048] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0050] In the present invention, according to the prior art, it is known that the valve device 30 is linked with the vertical rotation isolating vacuum circuit breaker 40. It can be known that the vertical rotation isolating vacuum circuit breaker 40 has an isolating state (horizontal state) and a working state (vertical state). In the working state, the upper end of the vertical rotation isolating vacuum circuit breaker 40 is connected to the contact box device 20 and connected to the inductance device 50.

[0051] Refer to Figures 1 - 4, the present invention discloses a vertically rotating indoor AC metal-enclosed switchgear, which includes a cabinet body 10, and a contact box device 20, a shutter device 30, a vertically rotating isolating vacuum circuit breaker 40, and an inductor device 50 arranged in the cabinet body 10 from top to bottom; a driving assembly 130 acts on the vertically rotating isolating vacuum circuit breaker 40 and the shutter device 30 synchronously; wherein, the driving assembly 130 drives the shutter device 30 and the vertically rotating isolating vacuum circuit breaker 40 to move. After the shutter device 30 is fully opened and stopped, the vertically rotating isolating vacuum circuit breaker 40 continues to move and passes through the shutter device 30 to be respectively connected to the contact box device 20 and the inductor device 50 above and below; and, the driving assembly 130 drives the shutter device 30 and the vertically rotating isolating vacuum circuit breaker 40 to move. After the vertically rotating isolating vacuum circuit breaker 40 withdraws from the shutter device 30 and is disconnected from the contact box device 20 and the inductor device 50 respectively, the shutter device 30 is fully closed, and the vertically rotating isolating vacuum circuit breaker 40 continues to move and reset.

[0052] Optionally, the shutter device 30 includes a guiding support 31, a fixed support 32, a first crank 33, a second crank 34, an output shaft 35, a third crank 36, a door frame 37, a shutter 38 and a stroke conversion seat 39; the door frame 37 is arranged in the cabinet body 10, and the shutter 38 is movably arranged on the door frame 37; the guiding support 31 is arranged in the cabinet body 10, and a guiding chute 310 is arranged on the guiding support 31. The guiding chute 310 includes a straight groove section 311 and a clamping groove section 312. The straight groove section 311 is arranged along the length direction of the guiding support 31, and a clamping groove section 312 is communicated on one side of the straight groove section 311; the output shaft 35 is rotatably arranged on the fixed support 32. One end of the first crank 33 is slidably arranged in the guiding chute 310, the other end of the first crank 33 is hinged to one end of the second crank 34, the other end of the second crank 34 is connected to one end of the output shaft 35, one end of the third crank 36 is connected to the other end of the output shaft, and the other end of the third crank 36 is a driving end, and the driving end acts on the shutter 38; a lifting part 391 is arranged on the stroke conversion seat 39, and the lifting part 391 is located between one end of the first crank 33 slidably connected to the guiding chute 310 and the fixed support 32; it is set that when one end of the first crank 33 is located in the clamping groove section 312, the distance between the fixed support 32 and the guiding support 31 is the largest. When the guiding support 31 continuously moves towards the direction close to the fixed support 32, the first crank 33 drives the second crank 34 to rotate, the second crank 34 drives the third crank 36 to rotate through the output shaft. When the guiding support 31 reaches a predetermined position, the lifting part 391 acts on the first crank 33, and one end of the first crank 33 slidably connected to the guiding chute 310 slides from the clamping groove section 312 into the straight groove section 311 and displaces relative to the straight groove section 311. The driving assembly 130 acts on the vertically rotating isolating vacuum circuit breaker 40 and the guiding support 31 respectively.

[0053] Among them, combined with Figures 5 - 13, the guiding support 31 is usually a sheet metal structure. Preferably, the guiding support 31 of the present application is an L-shaped structure, and the guiding chute 310 is arranged on one side plate of the L-shaped structure, and the other side plate is used to connect with an external transmission member; the fixed support 32 of this embodiment is arranged on one side of the guiding chute 310.

[0054] Specifically, the straight groove section 311 extends along the length direction of the side plate where it is located, the clamping groove section 312 is located at one end of the straight groove section 311, and the clamping groove section 312 extends towards the right-angle connection position between the two side plates. Particularly, in order for one end of the first crank 33 to smoothly switch between the straight groove section 311 and the clamping groove section 312, the included angle between the straight groove section 311 and the clamping groove section 312 should be less than 90°, and the connection position between the two can be rounded.

[0055] As an example, the fixed support 32 is a U-shaped support. The output shaft 35 can be selected as a cylindrical shaft, and it passes through both ends of the opening of the U-shaped fixed support 32. In this way, the fixed support 32 provides two-point support for the output shaft 35, ensuring the stability of the rotation of the output shaft 35. In addition, the fixed support 32 exists in the structure of a U-shaped sheet metal, and it has the characteristic of small weight.

[0056] One end of the first crank 33 can be provided with a slider or a sliding rod, and the slider or the sliding rod is slidably arranged in the guiding chute 310.

[0057] The second crank 34, one end of which is hinged to the other end of the first crank 33, and the other end of which is connected to one end of the output shaft 35.

[0058] One end of the third crank 36 is fixedly connected to the end of the output shaft 35 far from the second crank 34.

[0059] In this embodiment, the first crank 33 and the stroke conversion seat 39 are respectively arranged on the inner and outer sides of the side plate where the guiding chute 310 of the L-shaped guiding support 31 is located. As an example, the stroke conversion seat 39 can also be set as an L-shaped sheet metal structure with reference to the guiding support 31.

[0060] During the actual use process, see Figures 5 - 8 , in the initial state, one end of the first crank 33 is located in the clamping groove section 312, and the other end extends towards the direction close to the fixed support 32. Taking the height direction of the guiding support 31 as a reference, the movement of the guiding support 31 is divided into two stages. The movement of the guiding support 31 is divided into two stages.

[0061] The first stage: The guiding support 31 moves linearly towards the fixed support 32, and the clamping groove section 312 abuts against one end of the first crank 33. The first crank 33 rotates to drive the second crank 34 to rotate. Importantly, when the guiding support 31 moves to a predetermined position, at this time, the first crank 33, the second crank 34, and the third crank 36 rotate by a predetermined angle. At this time, the lifting part 391 acts on the first crank 33, and the height of one end of the first crank 33 located at the clamping groove section 312 rises and turns into the straight groove section 311.

[0062] See Figures 11 - 13 , The second stage: Under the continuous movement trend of the guiding support 31 towards the fixed support 32, one end of the first crank 33 located in the clamping groove section 312 is forced to enter the straight groove section 311 from the clamping groove section 312. In this way, the first crank 33 will not hinder the continuous movement of the guiding support 31. It can be understood that one end of the first crank 33 located in the guiding chute 310 no longer has an absolute displacement. One end of the first crank 33 located in the guiding chute 310 has a relative displacement in the straight groove section 311 when the guiding support 31 continues to move. When the guiding support 31 stops moving, the actions of this stage are completed.

[0063] On the contrary, that is, the transition from the second stage to the first stage, the guiding support 31 moves away from the fixed support 32 for reset. During this process, one end of the first crank 33 located in the guiding chute 310 gradually approaches the clamping groove section 312. When the guiding support 31 returns to the predetermined position, the lifting part 391 releases the action on the first crank 33. One end of the first crank 33 located in the guiding chute 310 falls back and enters the clamping groove section 312 again. The guiding support 31 returns to the initial position, and the first crank 33, the second crank 34, the output shaft 35, and the third crank 36 rotate in the reverse direction and return to the initial state.

[0064] According to the above, in addition to the linkage between the guiding support 31, the first crank 33, and the second crank 34; its motion relationship also includes: The rotation of the second crank 34 during the first stage will drive the output shaft 35 to rotate on the fixed support 32, and then drive the third crank 36 to rotate.

[0065] If the driving part for driving in the above structure is a rotating structure, such as the rotating door of a rotating switch, the driving end of the third crank 36 acts on the door shaft of the rotating door, and under the linkage of the external power source, it pushes the guiding support 31 to move. The entire structure drives the rotating door to open to a specified position in the first stage. In the second stage, the structure only moves following the external power source, and the structure no longer drives the rotating door to move until the external power source reaches the final position.

[0066] Before the above-mentioned first stage is set, the valve 38 is in a closed state, and the vertical rotation isolation vacuum circuit breaker 40 is in an isolated state. At this time, the entire vertical rotation isolation vacuum circuit breaker 40 is located below the valve device 30. Then, under the action of an external force source, the vertical rotation isolation vacuum circuit breaker 40 rotates from the isolated state to the working state, and the valve device 30 starts to enter the first stage. The valve 38 is opened under the action of the driving end, and the vertical rotation isolation vacuum circuit breaker 40 passes through the door frame 37 from the opened position of the valve 38. Importantly, at the beginning of the second stage, the valve 38 has been fully opened and satisfies the passage of the vertical rotation isolation vacuum circuit breaker 40, but the vertical rotation isolation vacuum circuit breaker 40 still rotates towards the working state. At this time, the valve 38 no longer moves synchronously with the vertical rotation isolation vacuum circuit breaker 40. In summary, the valve 38 stops moving after it is opened and satisfies the passage of the vertical rotation isolation vacuum circuit breaker 40. In this way, there is no need to set too much space on the valve device 30 for the movement space of the valve 38, directly reducing the space of the cabinet body 10 and better realizing miniaturization.

[0067] Optionally, the lifting part 391 includes a sliding groove 3911 and a lifting groove 3912. The sliding groove 3911 extends along the length direction of the stroke conversion seat 39 and is parallel to the straight groove section 311. The lifting groove 3912 is communicatively arranged on one side of the sliding groove 3911. Taking the height direction of the guiding support 31 as a reference, the straight groove section 311 is located above the sliding groove 3911. One end of the lifting groove 3912 away from the sliding groove 3911 extends towards the straight groove section 311, and one end of the clamping groove section 312 away from the straight groove section 311 extends towards the sliding groove 3911. It further includes a sliding pin 390. One end of the first crank 33 is slidably arranged in the straight groove section 311, the clamping groove section 312, the sliding groove 3911 and the lifting groove 3912 through the sliding pin 390. Among them, the sliding pin 390 is located in the clamping groove section 312. When the guiding support 31 continuously moves towards the fixed support 32, the sliding pin 390 moves from the sliding groove 3911 towards the lifting groove 3912, and the sliding pin 390 is introduced into the straight groove section 311 from the lifting groove 3912; and / or it further includes a transmission structure 60. The transmission structure 60 includes a sliding seat assembly 61 and two guide rails 62 arranged on the door frame 37. The sliding seat assembly 61 includes a connecting sliding seat 601. The two guide rails 62 are arranged in parallel. The connecting sliding seat 601 is slidably arranged on one guide rail 62. The third crank 36 is inserted into the connecting sliding seat 601, and the connecting sliding seat 601 moves relative to the third crank 36. The valve 38 is slidably arranged on the two guide rails 62, and the connecting sliding seat 601 acts on the valve 38 to drive the valve 38 to slide on the guide rail 62.

[0068] Optionally, a driving groove 611 is arranged on the connecting sliding seat 601. The length direction of the driving groove 611 forms an angle with the length direction of the guide rail 62. The third crank 36 is inserted into the driving groove 611.

[0069] Among them, a latch is provided at the driving end of the third crank 36, and the latch is inserted into the driving slot 611; the guide rail 62 is arranged on one side of the fixed support 32 where the latch is provided, and the guide rail 62 is arranged parallel to the straight slot section 311. The number of connecting sliders 601 is preferably one, and it is arranged on a guide rail 62 close to the fixed support 32; as described above, the third crank 36 is inserted into the driving slot 611 through the latch.

[0070] The key point is that a driving slot 611 is provided on the connecting slider 601. It should be noted that the driving slot 611 is a long slot, and the length of the driving slot 611 is related to the stroke length of the valve 38 to be opened or closed. It can be designed according to actual needs and is not limited here. In this embodiment, it is preferably that the driving slot 611 is perpendicular to the guide rail 62 in space.

[0071] As can be known from the above, the third crank 36 rotates following the output shaft 35. Therefore, when the latch rotates following the third crank 36, it acts on the side wall of the driving slot 611 to push the connecting slider 601 to move on the guide rail 62. It should be noted that the latch will also generate a displacement in the length direction of the driving slot 611 synchronously. Therefore, this is a process of converting rotation into linear motion, and the compactness of this structure is higher, saving space. In addition, when the connecting slider 601 slides on the guide rail 62, it naturally drives the valve 38 to move.

[0072] In this embodiment, the valve 38 can be directly connected to the connecting slider 601. The guide support 31 repeats the movement in the first stage and the second stage, thereby driving the latch to swing back and forth. Therefore, the valve 38 can perform repeated opening and closing, and the structure of this embodiment is well simplified.

[0073] In addition, the angle between the length direction of the driving slot 611 and the length direction of the guide rail 62 can also be other angles greater than 0° and less than 90°, such as 45°, 60°, etc.

[0074] In addition, for the convenience of description, the direction in which the guide support 10 moves towards the fixed support 20 is defined as the positive direction, and the opposite is the negative direction. In this embodiment, both the card slot section 112 and the lifting slot 1212 extend in the positive direction. Specifically, the card slot section 112 extends forward and downward at the front end of the straight slot section 111, and the lifting slot 1212 extends forward and upward. Particularly, the lower end of the card slot section 112 is not higher than the lower side edge of the sliding slot 1211, and the upper end of the lifting slot 1212 is not lower than the upper side edge of the straight slot section 111.

[0075] Combined with the above, in the initial state, the sliding pin 17 passes through the slot section 112 and the sliding groove 1211. The sliding pin 17 is located at one end of the sliding groove 1211 away from the lifting groove 1212. As the guiding support 10 moves forward in the positive direction, the sliding pin 17 finally abuts against the front side wall of the lifting groove 1212. The sliding pin 17 moves upward along the lifting groove 1212 and abuts against the top wall of the straight groove section 111. In this way, the sliding pin 17 enters the straight groove section 111. At this time, if the guiding support 10 continues to move forward, it will no longer drive the sliding pin 17. On the contrary, when the guiding support 10 moves in the reverse direction and the slot section 112 reconnects below the sliding pin 17, the sliding pin 17 re-enters the slot section 112 under the action of gravity, and then it returns to its original position, which will not be elaborated here.

[0076] Alternatively, the lifting part 121 can be a combination of a lifting mechanism and a sensor. The lifting mechanism can be a rack, a telescopic cylinder, etc. Sensors are respectively arranged on the lifting mechanism and in the slot section 112. The lifting mechanism is arranged on one side of the movement path of the guiding support 10. When the guiding support 10 moving in the positive direction from the initial state reaches a predetermined position, the sensors on the guiding support 10 and the lifting mechanism sense each other. The lifting mechanism lifts the sliding pin 17 from the slot section 112 upward from the bottom of the sliding pin 17 into the straight groove section 111. On the contrary, when the guiding support 10 moves in the reverse direction and returns to the predetermined position, the sensors sense each other again. At this time, the lifting mechanism retracts and the sliding pin 17 falls back into the slot section 112.

[0077] Optionally, a baffle 321 is arranged on the fixed support 32, and a notch is arranged on the baffle 321. The notch forms a clamping part 320.

[0078] Among them, a surrounding structure is formed on the periphery of the notch. The second crank 34 can rotate and be clamped into the notch. In this way, the second crank 34 in the notch is not prone to swing. In addition, the baffle 321 can be used for the fixed installation of the fixed support 32. If the second crank 34 needs a larger rotation angle, the depth dimension of the notch can be increased as required to avoid the second crank 34.

[0079] Optionally, the sliding seat assembly 61 further includes at least two sliding seats 602. At least one sliding seat 602 is slidably arranged on a guide rail 62. The valve 38 is slidably arranged on the guide rail 62 through the sliding seat 602.

[0080] Among them, there are implementable embodiments. One sliding seat 602 is arranged on each guide rail 62, and the valve is slidably arranged on the guide rail 62 through the sliding seat 602. Otherwise, to ensure that the valve 38 slides more smoothly on the guide rail 62, two sliding seats 602 are arranged on each guide rail 62 in this embodiment.

[0081] Optionally, the transmission structure 60 further includes a connecting member 63; one end of the connecting member 63 is rotatably connected to the connecting slider 601, the other end thereof is slidably connected to the valve 38, and the middle part of the connecting member 63 is rotatably arranged on the door frame 37.

[0082] Wherein, one end of the connecting member 63 is connected to the valve 38. In addition, a hinge hole 631 is provided in the middle part of the connecting member 63, and the hinge shaft passes through the hinge hole 631 and is fixed on the door frame 37. It should be particularly noted that the connecting member 63 is a flat rod-shaped structure, which is used to push the valve 38 to slide along the guide rail 62. In this embodiment, the hinge hole 631 is close to the end of the connecting member 63 connected to the connecting slider 601. Specifically, the distance from the center of the hinge hole 631 to the end of the connecting member 63 connected to the connecting slider 601 is defined as A, and the distance from the center of the hinge hole 631 to the end of the connecting member 63 connected to the valve 38 is defined as B. The ratio of A to B is preferably 1:9. The advantage of setting the ratio of A to B is that a very small sliding distance of the connecting slider 601 can drive the valve 38 to travel a large sliding distance, thus improving the concentration and compactness of the overall structure.

[0083] Optionally, a travel groove 381 is provided on the valve 38, and the length direction of the travel groove 381 is arranged at an angle to the length direction of the guide rail 62; one end of the connecting member 63 is rotatably connected to the connecting slider 601, and the other end thereof is slidably connected in the travel groove 381.

[0084] Wherein, in this embodiment, one end of the connecting member 63 is inserted into the travel groove 381 through a plug rod. Since the plug rod needs to move in the travel groove 381, the length of the travel groove 381 can be designed according to the displacement of the plug rod, and no limitation is made here. Importantly, the above-mentioned travel groove 381 is preferably provided at the middle position of the valve 38.

[0085] During the actual use process, in the initial state, one end of the first crank 33 is located in the card slot section 312, and the other end extends away from the straight slot section 311. The second crank 34 is located below the clamping portion 320, and the valve 38 is in the closed state.

[0086] Combined with the foregoing, during the first stage of the valve device 30, the third crank 36 rotates to push the connecting slider 601 to move on the guide rail 62 towards the valve 38. The connecting slider 601 pushes the connecting member 63 to rotate around the hinge rod. Thus, the plug rod at one end of the connecting member 63 moves in the travel groove 381 and acts on the side wall of the travel groove 381, and finally the valve 38 is opened. It should be noted that after the guide support 31 enters the second stage from the first stage, the guide support 31 is no longer linked to the valve 38, and at this time the valve 38 is stationary in the open state.

[0087] Conversely, that is, the transition from the second stage to the first stage. When the guiding support 31 rotates to the first stage, the connecting slider 601 drives the connecting member 63 to rotate in the reverse direction, and the connecting member 63 pushes the valve 38 to close.

[0088] In addition, an adjustable part is provided at one end of the connecting member 63 that is slidably connected to the travel groove 381, and the connection position between the external fixing member and the connecting member 63 is adjusted on the adjustable part.

[0089] Among them, the function of the adjustable part is to adjust the connection position of the insertion rod on the connecting member 63. The purpose is to prevent the insertion rod from being unable to be correspondingly installed with the travel groove 381 after the connecting member 63 is installed on the door frame 37. Therefore, the adjustable part is used to make the connection point of the insertion rod on the connecting member 63 adjustable to ensure that the insertion rod can be inserted into the travel groove.

[0090] In addition, the adjustable part includes a plurality of fixing holes 632 arranged along the length direction of the connecting member 63.

[0091] Among them, the fixing holes 632 can quickly realize the quick insertion of the insertion rod and conveniently adjust the position of the insertion rod. In addition, the adjusting part can be a strip-shaped groove, and the insertion rod can quickly move in the strip-shaped groove.

[0092] Optionally, referring to Figure 32 , the contact box device 20 includes a box body 21 and a vertical bus bar 22; the vertical bus bar 22 is arranged on the top of the box body 21, the width direction of the vertical bus bar 22 is parallel to the height direction of the box body 21, and the bottom side of the vertical bus bar 22 extends into the box body 21.

[0093] Among them, the external structure of the box body 21 is usually square or similar to a square structure, the middle part of the box body 21 is hollow and the bottom is an open structure. According to the foregoing, when the vertical rotary isolating vacuum circuit breaker 40 is in the working state, its upper end turns from the bottom of the box body 21 into the inside of the box body 21 and is connected to the vertical bus bar 22.

[0094] Specifically, the vertical bus bar 22 of this embodiment is a thin plate structure; an installation groove is arranged along the length direction on the top of the box body 21. Particularly, both ends of the installation groove are open ends and the bottom is communicated with the inside of the box body 21; after the vertical bus bar 22 is clamped in the installation groove, the lower edge of the vertical bus bar 22 extends into the box body 21, and both ends protrude from both ends of the installation groove respectively.

[0095] The number of the contact box devices 20 is three, and the three box bodies 21 are arranged in parallel in the cabinet 10 and are located on the top of the valve device 30. In addition, referring to Figure 2Or 4. The vertical busbars 22 are arranged front and back in the cabinet body 10. Compared with the existing contact box devices, in the contact box device of this embodiment, the three-phase busbars of the ordinary contact box device are usually supported by insulators, and the middle phase is misaligned due to insulation requirements. Especially in the busbar structure arranged in the order of back, middle, and front, the width of the vertical rotation indoor AC metal-enclosed switchgear is increased, making installation difficult.

[0096] Optionally, a first heat dissipation hole 201 is provided on the top surface of the box body 21.

[0097] Among them, the first heat dissipation hole 201 penetrates the top surface of the box body 21 to communicate with the inside of the box body 21, and the first heat dissipation hole 201 is arranged along the length direction of the installation groove. Specifically, at least one through hole is provided on the side wall of the first heat dissipation hole 201 close to the installation groove. The through hole communicates the installation groove and the first heat dissipation hole 201. The bolt passes through the through hole from the first heat dissipation hole 201 and abuts against the side surface of the vertical busbar 22. The first heat dissipation hole 201 and the vertical busbar 22 are both arranged on the top of the box body 21, and the first heat dissipation hole 201 can effectively and quickly dissipate the heat generated by the vertical busbar 22.

[0098] Optionally, refer to Figure 14 Or Figure 15 , the vertical rotation isolating vacuum circuit breaker 40 includes a pole column assembly 41, an operating mechanism 42 and a frame 43; the cabinet body 10 is provided with an installation cavity communicating with the outside; the frame 43 is movably arranged in the installation cavity and moves along the depth direction of the installation cavity, and has a working position and a maintenance position in the installation cavity; the pole column assembly 41 and the operating mechanism 42 are arranged on the frame 43 and withdraw from or enter the installation cavity following the movement of the frame 43; when the frame 43 is pushed into the installation cavity and reaches the working position, the pole column assembly 41 and the operating mechanism 42 enter and are hidden in the installation cavity.

[0099] Specifically, the frame 43 includes two parallel support bars 431 and a connecting bar 432; both ends of the connecting bar 432 are respectively connected to the closer ends of the two support bars 431. Or, the frame 43 includes two parallel support bars 431, a connecting bar 432 and two vertical bars 433; both ends of the connecting bar 432 are respectively connected to the closer ends of the two support bars 431, the lower ends of the two vertical bars 433 are respectively connected to the closer ends of the two support bars 431, and both ends of the connecting bar 432 are respectively connected to the upper ends of the two vertical bars 433; among them, the operating mechanism 42 is arranged on the two support bars 431, the support bars 431 are arranged on the cabinet body 10, and the pole column assembly 41 is rotatably arranged on the operating mechanism 42 and is respectively connected to the contact box device 20 and the inductance device 50 up and down.

[0100] Among them, various operating mechanisms are provided in the operating mechanism 42. The pole column assembly 41 is arranged on one side of the operating mechanism 42. Two support bars 431 and one connecting bar 432 form a U-shaped bracket. Both the operating mechanism 42 and the pole column assembly 41 are arranged on the aforementioned bracket. In this embodiment, the pole column assembly 41 and the operating mechanism 42 are arranged on the vehicle frame 43. The support bars 431 and the connecting bar 432 of the vehicle frame 43 can be made of section steel, which has higher strength and provides a stable bracket.

[0101] In addition, on the basis of the above, the vehicle frame 43 includes two vertical bars 433. The vertical bars 433 are arranged on the tops of the support bars 431. Compared with the aforementioned embodiment of the present invention, a spatial bracket is formed in this way. The spatial bracket surrounds the pole column assembly 41 and the operating mechanism 42 in space, improving the stability of the support. In this embodiment, the operating mechanism 42 is located at one end of the support bar 431 away from the connecting bar 432.

[0102] Furthermore, a grounding part is arranged on the support bar 431. The grounding part is usually a grounding metal plate. The grounding part protrudes from the outside of the support bar 431. There is an extension bar in the cabinet 10. The bottom end of the extension bar is connected to the bottom of the cabinet 10. When the support bar 431 reaches the working position, the grounding part contacts the top end of the extension bar.

[0103] Optionally, it further includes two mounting bars 434. The two mounting bars 434 are respectively arranged on the two support bars 431. The mounting bars 434 extend along the direction of the vertical bar 433. The operating mechanism 42 is fixed to the mounting bars 434 by bolts.

[0104] Among them, the mounting bar 434 is arranged on the top of the support bar 431. Preferably, the mounting bar 434 is located at one end of the support bar 431 away from the connecting bar 432. The mounting bar 434 can be used for fixing the operating mechanism 42.

[0105] Optionally, the two support bars 431 are movably arranged in the installation cavity and move along the depth direction of the installation cavity, and have a working position and a maintenance position in the installation cavity; the pole column assembly 41 and the operating mechanism 42 follow the movement of the support bar 431 to exit or enter the installation cavity; when the support bar 431 is pushed into the installation cavity and reaches the working position, the support bar 431, the connecting bar 432, the vertical bar 433, the pole column assembly 41, and the operating mechanism 42 enter and are hidden in the installation cavity.

[0106] Wherein, one end of the installation cavity is an opening, and this opening is arranged on the side surface of the cabinet body 10. The support strip 431 is located in the installation cavity. It can be understood that the support strip 431 moves in the width direction (left - right direction) of the cabinet body 10. As can be known from the foregoing, the pole column assembly 41 has a working state and an isolation state. When the pole column assembly 41 is in the isolation state, the vertical rotation isolation vacuum circuit breaker 40 is pulled out of the installation cavity. When the maximum position is reached, it reaches the maintenance position, and maintenance work can be carried out at this position. It can be understood that when the vertical rotation isolation vacuum circuit breaker 40 at the maintenance position is completely pushed into and hidden in the installation cavity, it reaches the working position at this time.

[0107] Further, taking the cross - section of the support strip 431 as a square as an example, to ensure the stable movement of the support strip 431, two L - shaped support rails are arranged at the bottom of the installation cavity. The L - shaped openings of the two support rails face each other to form a wrapping limit. One support strip 431 is correspondingly arranged in one support rail, and the support strip 431 can slide in the support rail. Preferably, to reduce the friction between the support strip 431 and the support rail, rollers are arranged at the bottom of the support strip 431. For example, two rollers are arranged along the length of the support strip 431, and the rollers convert the friction between the support strip 431 and the support rail from sliding friction to rolling friction, reducing the movement resistance.

[0108] In summary, in this embodiment, using a strip - shaped support strip 431, etc. as the support structure of the pole column assembly 41 and the operating mechanism 42 will basically not cause obstruction in the height direction of the cabinet body 10, thus facilitating the wiring connection inside the vertical rotation indoor AC metal - enclosed switchgear.

[0109] Optionally, referring to Figure 24 and Figure 28 , the vertical rotation isolation vacuum circuit breaker 40 further includes a positioning assembly 44. Along the movement direction of the support strip 431, at least one side of the support strip 431 is provided with a positioning assembly 44. The positioning assembly 44 includes an elastic member 441 and a positioning member 442. At least one side of the support strip 431 is provided with a positioning member 442, and the elastic member 441 is arranged on the operating mechanism 42 and acts on the positioning member 442. A first positioning hole is arranged on the inner wall of the installation cavity. When the support strip 431 reaches the working position, the elastic member 441 provides an elastic force to push the positioning member 442 to move and insert into the first positioning hole, and the positioning member 442 restricts the movement of the support strip 431 in the depth direction of the installation cavity; and / or, the positioning assembly 44 further includes a plug - in member 443. Along the direction of the support strip 431 moving from the working position to the maintenance position, the connecting strip 432 is located at the front end of the support strip 431, and a plug - in member 443 is arranged on the front side of the connecting strip 432. A second positioning hole is arranged on the inner wall of the installation cavity. When the support strip 431 reaches the working position, the plug - in member 443 is inserted into the second positioning hole to restrict the movement of the support strip 431 to both sides in the depth direction of the installation cavity.

[0110] Among them, the vertical rotation isolating vacuum circuit breaker 40 enters and exits the installation cavity and has a maintenance position and a working position at different locations. After the vertical rotation isolating vacuum circuit breaker 40 reaches the working position, it generally switches to the working state, so the vertical rotation isolating vacuum circuit breaker 40 in the working position needs to be locked. Taking the direction from the maintenance position to the working position as the reference direction (at this time, the pole assembly 41 is in the front and the operating mechanism 42 is in the rear), elastic members 441 and positioning members 442 are arranged on both sides of the operating mechanism 42 in this embodiment. The elastic member 441 is a spring, and the positioning member 442 is selected as a cylinder. A chamfer is provided at one end of the positioning member 442 inserted into the first positioning hole, and the chamfer side wall is used to act on the side wall of the installation cavity, thereby pushing the elastic member 441 to compress, and the chamfer side wall interacts with the side wall of the first positioning hole. Under the action of an external force, the positioning member 442 can be disengaged from the first positioning hole. In addition, a plug-in member 443 is provided at the front end of the vehicle frame 43. The plug-in member 443 is also selected as a column, and the front end is preferably a tip for easy insertion into the second positioning hole. The above-mentioned first positioning hole and second positioning hole can both be provided on the inner wall of the cabinet 10.

[0111] Preferably, the installation relationship between the elastic member 441 and the positioning member 442 can be: there are access holes for the positioning member 442 to enter and exit on both sides of the operating mechanism 42. Along the axial direction of the access holes, a support plate is provided in the operating mechanism 42. The positioning member 442 passes through the support plate and the access holes at the same time. In addition, the cylinder is provided with two sets of protrusions. The first set of protrusions is located between the support plate and the access port, and the second set of protrusions is located on the side of the support plate away from the access holes. The elastic member is sleeved on the positioning member 442 and is located between the first set of protrusions and the support plate. In summary, when the positioning member 442 moves inward into the operating mechanism 42, the first set of protrusions compresses the elastic member 441. On the contrary, the compressed elastic member 441 releases and pushes the first set of protrusions, thereby pushing it to move outward; here, the second set of protrusions is used to prevent the positioning member 442 from falling out of the access hole under the action of the elastic member 441.

[0112] In addition, as known from the foregoing, the positioning member 442 is squeezed by the inner wall of the installation cavity or the inside of the first positioning hole to move and contract toward the operating mechanism 42. Further, in order to facilitate pushing the positioning member 442 to contract and move inside the operating mechanism 42, a handle 444 is also provided in this embodiment. Specifically, a control groove is provided on the side of the operating mechanism 42 facing away from the pole assembly 41. The control groove is horizontally arranged and at the same height as the positioning member 442. Both ends of a handle 444 are respectively connected to two sets of protrusions on a positioning bracket and are exposed outside the operating mechanism 42. In this way, it is more convenient to control the positioning member to exit the first positioning hole through the handle 444. In addition, the handle 444 pushes and pulls the entire vertical rotation isolating vacuum circuit breaker 40 into or out of the installation cavity.

[0113] Optionally, in combination with Figure 16 and Figure 17, the terminal post assembly 41 includes a terminal post 411, a longitudinal beam 412, and a driving mechanism 413; the longitudinal beam 412 includes a base post 4121, a sealing plate 4122, a first end plate 4123, and a second end plate 4124. An opening is provided on one side of the terminal post 411, and the sealing plate 4122 is arranged at the opening to form an enclosed cavity inside the base post 4121 and the sealing plate 4122; a first shaft hole 41231 is provided on the first end plate 4123, and a second shaft hole 41241 is provided on the second end plate 4124. The first end plate 4123 and the second end plate 4124 are respectively arranged at both ends of the enclosed cavity to close both ends of the enclosed cavity. Along the axial direction of the enclosed cavity, the projections of the first shaft hole 41231 and the second shaft hole 41241 are located outside the projection of the enclosed cavity, and the first shaft hole 41231 and the second shaft hole 41241 are coaxially arranged; an installation post is respectively provided on the operating mechanism 42 and the vehicle frame 43, and the two installation posts are coaxial. The first shaft hole 41231 and the second shaft hole 41241 are respectively rotatably arranged on one installation post, and the first shaft hole 41231 and the second shaft hole 41241 are respectively rotatably sleeved on one installation post to realize the rotation of the longitudinal beam 412 on the operating mechanism 42; the driving mechanism 413 is arranged in the enclosed cavity and acts on the terminal post 411 to control the opening and closing of the terminal post 411.

[0114] Among them, according to the prior art, the terminal post 411 and the driving mechanism 413 are known and will not be elaborated here. The vertical-rotation indoor AC metal-enclosed switchgear of this embodiment is for three-phase high-voltage electricity, so the number of terminal posts 411 is the same as the number of box bodies 21, both being three. The three terminal posts 411 are arranged along the length direction of the longitudinal beam 412.

[0115] Optionally, the base post 4121 includes a base plate and a first bending plate and a second bending plate that are oppositely arranged on both sides of the base plate and extend in the same direction. The extension length of the first bending plate is greater than that of the second bending plate. An opening is formed between the first bending plate and the second bending plate. A closing plate extending towards the second bending plate is provided at one end of the first bending plate away from the base plate; the sealing plate 4122 arranged at the opening is located inside the closing plate; the first bending plate and the sealing plate 4122 are respectively provided with a first avoidance hole 41210 and a second avoidance hole 41220 for the driving mechanism 413 to pass through and act on the terminal post 411. In the direction perpendicular to the axial direction of the enclosed cavity, the first avoidance hole 41210 and the second avoidance hole 41220 are aligned; and / or, the first bending plate is provided with a plug hole 41211, and the sealing plate 4122 is provided with a plug projection 41221 inserted into the plug hole 41211.

[0116] Among them, the focus of this embodiment lies in the longitudinal beam 412. The base plate, the first bending plate, and the second bending plate form a U-shaped plate member. The base column 4121 can be directly formed by bending the whole plate, thereby improving the overall strength of the base column 4121. The sealing plate 4122 is arranged at the opening of the base column 4121. One side edge of the sealing plate 4122 is connected to the side edge of the second bending plate away from the base plate, and the other side edge is connected to the side surface of the first bending plate close to the second bending plate. At the same time, the sealing plate 4122 is located inside the converging plate, and the sealing plate 4122 and the base plate are parallel to each other. Thus, the base plate, the first bending plate, the second bending plate, the sealing plate, and the converging plate form a square enclosing cavity. The first end plate 4123 and the second end plate 4124 are respectively and hermetically arranged at both ends of the square enclosing cavity.

[0117] Specifically, an installation post is arranged on the side wall of the operating mechanism 42 close to the pole column 411, and an installation post is arranged at the midpoint position of the connecting bar 432. The two installation posts are arranged facing each other. In this way, the first shaft hole and the second shaft hole are respectively installed on the installation posts, and at this time, the first shaft hole is close to the operating mechanism 42. A reinforcing rib 4125 connecting the two is arranged between the outer sides of the first end plate 4123 and the sealing plate 4122. Specifically, the number of the reinforcing ribs 4125 is two, and the two reinforcing ribs 4125 are respectively arranged on both sides of the first shaft hole.

[0118] In addition, three first avoidance holes 41210 are arranged on the first bending plate, and three second avoidance holes 41220 are arranged on the sealing plate 4122. It can be known from the prior art that the driving mechanism 413 passes through the first avoidance holes 41210 and the second avoidance holes 41220 and acts on the three pole columns 411 respectively, which will not be elaborated here.

[0119] Optionally, the driving mechanism 413 includes a rotating shaft 4131, a connecting rod 4132, a connecting arm 4133, a buffer member 4134, and at least one hinge ear 4135; the connecting rod 4132 is hinged to the rotating shaft 4131, and the connecting rod 4132 is arranged along the radial direction of the rotating shaft 4131, and the connecting rod 4132 is connected to the pole column 411; one end of the connecting arm 4133 is connected to the rotating shaft 4131, and the other end acts on the buffer member 4134; the rotating shaft 4131 and the buffer member 4134 are arranged in the operating mechanism 42; the rotating shaft 4131 rotates forward or backward to push the connecting rod 4132 to make a reciprocating motion along its own length direction. Among them, when the buffer member 4134 moves in one of the forward rotation or backward rotation of the rotating shaft 4131, the buffer member 4134 exerts a reverse acting force on the rotation of the rotating shaft 4131 through the connecting arm 4133; one end of the hinge ear 4135 is hinged to the connecting rod 4132, and the other end is hinged to the rotating shaft 4131.

[0120] Among them, according to the prior art, the transmission module of this embodiment is applied to a vertical rotary vacuum circuit breaker; the longitudinal beam 412 is rotatably arranged on the operating mechanism 42; the driving mechanism 413 is arranged in the longitudinal beam 412 and connected to the three-phase pole columns. The closing and opening of the three-phase pole columns are controlled by the insulating pull rod through the connecting rod 4132, which will not be elaborated here.

[0121] In this embodiment, one end of the connecting rod 4132 is hinged to the rotating shaft 4131 and is arranged in the horizontal direction. Preferably, the whole connecting rod 4132 is located above or below the horizontal plane where the rotating shaft 4131 is located (this embodiment takes the upper side as an example); the significance of such a setting is that: the rotating shaft 4131 drives the linear motion of the connecting rod 4132 through its own rotation. When the whole connecting rod 4132 is located above or below the horizontal plane where the rotating shaft 4131 is located, when the rotating shaft 4131 rotates to a specific angle, especially when the hinge point of the connecting rod 4132 and the rotating shaft 4131 rotates from one side of the rotating shaft 4131 to the equal height point on the other side of the rotating shaft 4131. At this time, the moving distance of the hinge point of the connecting rod 4132 and the rotating shaft 4131 in the vertical direction is small, and the connecting rod 4132 jumps less in the vertical direction, ensuring the stability of the movement of the connecting rod 4132 and that the connection between the connecting rod 4132 and the rotating shaft 4131 is not easily jammed, avoiding the rotating shaft 4131 from being unable to reach a specific rotation angle. One end of the connecting arm 4133 is fixedly arranged on the rotating shaft 4131, and the other end is a free end, and the position of the free end changes as the rotating shaft 4131 rotates.

[0122] In this embodiment, taking the opening state as the initial state, at this time, the free end of the connecting arm 4133 is on one side of the rotating shaft 4131. And the free end is at the lowest point. The buffer 4134 is located below the free end and is in a compressed state. At this time, the hinge point of the connecting rod 4132 and the rotating shaft 4131 and the connecting arm 4133 may be on the same side of the rotating shaft 4131 or on the opposite side due to the magnitudes of the forward and reverse rotation angles, but it can be determined that in this state, the whole connecting rod 4132 is in the state closest to the rotating shaft 4131. For the convenience of description, at this time, it is described with the hinge point of the connecting rod 4132 and the rotating shaft 4131 and the connecting arm 4133 being on the same side of the rotating shaft 4131.

[0123] Next, refer to Figure 19 or Figure 20, when the rotating shaft 4131 rotates forward (clockwise), the free end of the connecting arm 4133 generates a displacement upward, the buffer member 4134 extends upward following the connecting arm 4133, the whole connecting rod 4132 moves in a direction away from the rotating shaft 4131, and the connecting rod 4132 closes the pole column through the lower contact. After the closing is completed, the rotating shaft 4131 stops rotating forward, the free end of the connecting arm 4133 reaches the highest point, and the buffer member 4134 is in an extended state. It should be noted that at this time, the hinge point between the connecting rod 4132 and the rotating shaft 4131 and the connecting arm 4133 are located on the opposite side of the rotating shaft 4131. In addition, the forward rotation of the rotating shaft 4131 in this embodiment can be driven by a motor.

[0124] Conversely, if the pole column is opened, refer to Figure 22 or Figure 23 , at this time, the connecting rod 4132 is released, the whole connecting rod 4132 returns in a direction close to the rotating shaft 4131, the rotating shaft 4131 rotates reversely (counterclockwise), the connecting arm 4133 moves from the highest point to the lowest point. At this time, the buffer member 4134 provides resistance when the free end rotates downward, thereby providing buffering for the connecting rod 4132 to return to its position. After the above components return to the initial state, it is the open state at this time; as can be known from the prior art, a tripping spring 160 is connected to the rotating shaft 4131. When the rotating shaft 4131 rotates forward, the tripping spring 160 is stretched, and the tripping spring 160 provides the power for the reverse rotation of the rotating shaft 4131 through the restored pulling force, which will not be elaborated here.

[0125] Optionally, the driving mechanism 413 further includes at least one hinge ear 4135; one end of the hinge ear 4135 is hinged to the connecting rod 4132, and the other end is hinged to the rotating shaft 4131. The connecting rod 4132 is hinged to the rotating shaft 4131 through the hinge ear 4135.

[0126] Among them, the hinge ear 4135 has a straight groove structure. Preferably, the length of the hinge ear 4135 is greater than or equal to the diameter of the rotating shaft 4131. In this way, the hinge ear 4135 can swing around the rotating shaft 4131 with sufficient length, and the relative movement fluctuation between the two ends of the hinge ear 4135 is small, so the influence on the connecting rod 4132 is also relatively small.

[0127] More preferably, the number of the hinge ears 4135 is two, and the two hinge ears 4135 are respectively arranged on both sides of the connecting rod 4132.

[0128] Among them, it can be understood that the two hinge ears 4135 ensure the connection stability between the connecting rod 4132 and the rotating shaft 4131.

[0129] Optionally, the driving mechanism 413 further includes a driving crank arm 4136, a driving cam 4138, and a brake block 4139. The driving crank arm 4136 includes a connecting seat 41361 and an extending arm 41362. The connecting seat 41361 is disposed on the rotating shaft 4131, and the articulated ear 4135 is articulated to the connecting seat 41361. One end of the extending arm 41362 is disposed on the connecting seat 41361, and the other end, as an abutting end 413621, extends radially away from the rotating shaft 4131 along the rotating shaft 4131. The driving cam 4138 is rotatably disposed below the free end, and one side of the driving cam 4138 is defined as a driving surface 41381. One end of the driving surface 41381 extends away from the rotation center of the driving cam 4138 to be used as a driving end 41381, and the driving surface 41381 abuts below the abutting end 413621. The brake block 4139 is rotatably disposed above the extending arm 41362, and one end of the brake block 4139 is used as a braking end 41391, and the braking end 41391 is disposed toward the top of the extending arm 41362. Wherein, the driving cam 4138 rotates counterclockwise and drives the extending arm 62 and the rotating shaft 4131 to rotate clockwise. When the driving end 41381 rotates from the lowest point to the highest point, it abuts against the abutting end 413621 that rotates from the lowest point to the highest point. The top of the extending arm 41362 abuts against the braking end 41391 and stops rotating, and one end of the connecting arm 4133 connected to the buffer member 4134 is at the highest point. The brake block 4139 rotates counterclockwise, the braking end 41391 acts on the top of the extending arm 41362 and drives the extending arm 41362 to rotate counterclockwise. The extending arm 41362 drives the rotating shaft 4131 to rotate counterclockwise and the driving cam 4138 to rotate clockwise until the driving end 41381 and the abutting end 413621 return to their respective lowest points.

[0130] Wherein, the connecting seat 41361 includes two articulated plates, and one end of the connecting rod 4132 can be directly articulated between the two articulated plates; alternatively, the two articulated ears 4135 are correspondingly connected to the two articulated plates.

[0131] Exemplarily, the connecting seat 41361 is a square block, and the connecting seat 41361 is disposed in the middle of the rotating shaft 441381. The extending arm 41362 is on the side of the rotating shaft 441381 away from the connecting rod 4132 and extends in a direction away from the connecting rod 4132.

[0132] Combined with the foregoing description, in the initial state, the free end of the connecting arm 4133 is at its lowest point, and the extending arm 41362 is disposed obliquely downward. Preferably, the top surface of the extending arm 41362 is a downward inclined surface that is inclined downward; the driving surface 41381 is an arc surface. Specifically, according to the prior art, the cam body is a circular body, one end of the arc surface is tangent to the outer wall of the circle, and the other end extends outward, which will not be elaborated here. The brake block 41391 is a strip-shaped structure.

[0133] Similarly, at this time, both the abutting end 413621 and the driving end 413811 are at their respective lowest points. In this embodiment, the driving cam 4138 rotates forward or backward as the driving rotating shaft 441381. Therefore, the above-mentioned extension arm 41362 rotates counterclockwise to lift the extension arm 41361. The driving end 413811 and the abutting end 413621 contact at their respective highest points. At this time, the braking end 413911 abuts against the downward inclined surface to prevent the driving cam 4138 from rotating too much and avoid the separation of the driving cam 4138 and the extension arm 41362. Most importantly, during this process, the extension arm 41361 drives the southeast rotating shaft 441381 to rotate clockwise, so it drives the movement of the connecting rod 4132. On the contrary, the counterclockwise rotation of the driving cam 4138 requires the counterclockwise rotation of the braking block 41391 to drive. At this time, the rotating shaft 441381 rotates counterclockwise. Finally, the driving end 413811 and the abutting end 413621 rotate back to their respective lowest points.

[0134] For example, in this embodiment, the driving cam 4138 and the braking block 41391 can be driven by an existing energy storage mechanism (energy storage motor) because the energy storage mechanism can be driven actively or passively to facilitate the mutual driving conversion between the braking block 41391 and the driving cam 4138 as described above.

[0135] Optionally, the driving crank arm 4136 further includes an abutting wheel 41340; the abutting wheel 41340 is rotatably arranged at the abutting end 413621, and the abutting end 413621 acts on the driving cam 4138 through the abutting wheel 41340.

[0136] Among them, as described above, the abutting end 413621 abuts and frictions with the driving surface 41381 during the lifting process. Here, the abutting wheel 41340 changes the sliding friction into rolling friction, reducing the frictional force.

[0137] Optionally, the driving mechanism 413 further includes a runner 4137. The runner 4137 is rotatably arranged at one end of the connecting arm 4133 away from the rotating shaft 4131, and one end of the buffer member 4134 is connected to the runner 4137.

[0138] Among them, based on the foregoing, it can be known that the free end moves in a rotating manner. Thus, the free end has both lateral movement and vertical movement. Therefore, the buffer member 4134 is movably connected to the connecting arm 4133 through the runner 4137 to prevent the buffer member 4134 from getting stuck when interacting with the free end.

[0139] In addition, the buffer member 4134 is an oil buffer. The oil buffer belongs to the prior art and will not be elaborated here. It should be noted that the oil buffer has the characteristics of strong resistance and good buffering effect. Alternatively, the buffer member 4134 can be a spring. Specifically, the free end is at the highest point, and at this time the spring is in a natural length state. When the free end rotates downward, the spring compresses and provides an upward elastic force for impedance.

[0140] It should be noted that since the forward and reverse rotation angles of the rotating shaft 4131 are relatively small, the lateral displacement of its free end is relatively small (the free end is always on the same side of the rotating shaft 4131). Thus, it is ensured that even if the buffer member 4134 does not have a lateral following movement, its vertical movement will not get stuck.

[0141] Optionally, the connecting rod 4132 includes a rod body 41321 and an adjusting member 41322; the adjusting member 41322 includes a stud 413221, a screw seat 413222, and a locking screw seat 413223. One end of the screw seat 413222 is provided with a connecting screw hole, the other end of the screw seat 413222 is connected to the rod body 41321. One end of the stud 413221 is hinged to the rotating shaft 4131, and the other end is screwed into the connecting screw hole. The locking screw seat 413223 is screwed onto the stud 413221 and is located outside the connecting screw hole. The locking screw seat 413223 spirally approaches the screw seat 413222 and abuts against the screw seat 413222. Specifically, the rod body 41321 is hinged to the hinge ear 4135.

[0142] Among them, in this embodiment, the outer contour of the locking screw seat 413223 is a regular hexagon structure, so that the locking screw seat 413223 can be conveniently rotated by an open-end wrench.

[0143] Optionally, a middle door is movably arranged at a position on the cabinet body 10 corresponding to the vertical rotation isolating vacuum circuit breaker 40. The middle door is opened or closed to close or open the installation cavity; the pole column assembly 41 further includes an isolating motor 414 arranged in the operating mechanism 42. The isolating motor 414 acts on the longitudinal beam 412, and a manual operation contact 4140 is arranged on the isolating motor 414. The end of the manual operation contact 4140 far from the isolating motor 414 is an external free end; the vertical rotation isolating vacuum circuit breaker 40 further includes an isolating operation interlocking mechanism 45. The isolating operation interlocking mechanism 45 includes a middle door interlocking assembly 451 and a closing-opening interlocking assembly 452. Both the middle door interlocking assembly 451 and the closing-opening interlocking assembly 452 are arranged on one side of the external free end. The middle door acts on the middle door interlocking assembly 451, and the closing-opening interlocking assembly 452 is connected to the driving mechanism 413; when the middle door is opened, the middle door interlocking assembly 451 blocks on one side of the external free end to prevent the external operation handle from docking with the external free end; when the middle door is closed, the external operation handle acts on the middle door interlocking assembly 451 to make the middle door interlocking assembly 451 rotate and give way, and the external operation handle docks with the external free end; when the pole column 411 is closed, the closing-opening interlocking assembly 452 blocks on one side of the external free end to prevent the external operation handle from docking with the external free end; when the pole column 411 is opened, the external operation handle acts on the middle door interlocking assembly 451 to make the middle door interlocking assembly 451 rotate and give way, and the external operation handle docks with the external free end.

[0144] Wherein, the middle door is rotatably arranged at the opening of the installation cavity where the vertical rotation isolating vacuum circuit breaker 40 is movably arranged. After the vertical rotation isolating vacuum circuit breaker 40 enters the installation cavity, the middle door can close the opening of the installation cavity. As can be known from the prior art, the isolating motor 414 is used to control the forward and reverse rotation of the longitudinal beam 412, and the manual operation contact 4140 is used for the connection control of the operation handle. At this time, the manual operation contact 4140 is preferably arranged in a hexagonal shape. The free end of the manual operation contact 4140 faces the middle door (in the direction away from the pole column 411). In addition, an insertion hole for inserting the external operation handle is arranged on the middle door.

[0145] Optionally, refer to Figure 25 and Figure 26, the middle door interlock assembly 451 includes a first mounting seat 4511, a blocking fork 4512 and a linkage rod 4513; the first mounting seat 4511 is arranged on the operating mechanism 42, the blocking fork 4512 includes a blocking rod 45121, the blocking rod 45121 is rotatably arranged on the first mounting seat 4511 and rotates in the horizontal direction, and one end of the blocking rod 45121 is arranged on one side of the external free end. The linkage rod 4513 includes an abutting rod 45131 and a driving rod 45132 that are rotatably arranged on the operating mechanism 42. One end of the abutting rod 45131 is connected to one end of the driving rod 45132, and the abutting rod 45131 and the driving rod 45132 rotate in the vertical direction. The abutting rod 45131 is located on the side of the blocking rod 45121 close to the manual operation contact 4140; when the middle door is closed, the driving rod 45132 drives the abutting rod 45131 to rotate in the vertical direction, and a height difference is formed between the end of the abutting rod 45131 far from the driving rod 45132 and the blocking rod 45121 in the vertical direction to avoid the rotation of the blocking rod 45121 in the horizontal direction.

[0146] Among them, the first mounting seat 4511 is an L-shaped plate, the L-shaped plate is arranged downward, the vertical plate of the L-shaped plate is connected to the operating mechanism 42, and the blocking fork 4512 is rotatably arranged on the horizontal plate. Specifically, one end of the blocking rod 45121 is rotatably arranged on the horizontal plate of the first mounting seat 4511, and the other end extends to block the end of the free end of the manual operation contact 4140. The linkage rod 4513 rotates in the vertical direction. Specifically, the end of the abutting rod 45131 far from the driving rod 45132 is lapped on the horizontal plate of the first mounting seat 4511;

[0147] In this embodiment, when the middle door is closed, the inner side of the middle door abuts against the outer side of the driving rod 45132, the driving rod 45132 rotates inward, the abutting rod 45131 is lifted upward. After the middle door is completely closed, the abutting rod 45131 and the blocking rod 45121 are misaligned. If the vertical rotation isolating vacuum circuit breaker 40 is in the open state at this time, at this time, both the middle door interlock assembly 451 and the closing and opening interlock assembly 452 can be driven and avoided by an external operation handle, and the external operation handle and the manual operation contact 4140 can be engaged. On the contrary, when the middle door is opened, the inner side of the middle door is disengaged from the abutment with the driving rod 45132, and the driving rod 45132 rotates outward and resets, and the abutting rod 45131 rotates downward and resets.

[0148] Optionally, the middle door interlock assembly further includes a first reset member 4514. The first reset member 4514 is disposed on the first mounting seat 4511 and acts on the side of the shift lever 45121 close to the manual operation contact 4140. When the external operation handle abuts against the shift lever 45121 and docks with the external freedom, the shift lever 45121 rotates towards the manual operation contact 4140 and deforms the first reset member 4514. When the external operation handle withdraws and releases the docking with the manual operation contact 4140, the first reset member 4514 releases and pushes the shift lever 45121 to reset.

[0149] Wherein, the first reset member 4514 is a spring. One end of the spring is connected to the first mounting seat 4511, and the other end is connected to the shift lever 45121. When the external operation handle drives the shift lever 45121 to avoid, the shift lever 45121 rotates inward and compresses the first reset member 4514. After the external operation handle withdraws, the first reset member 4514 drives the shift lever 45121 to return to its original position. In another embodiment, the blocking fork 4512 further includes a return lever 45122. One end of the return lever 45122 is connected to one end of the shift lever 45121. An obtuse angle structure is formed between the return lever 45122 and the shift lever 45121. The connecting end of the two is rotatably connected to the transverse plate of the first mounting seat 4511. One end of the first reset member 4514 is connected to the first mounting seat 4511, and the other end is connected to the return lever 45122. When the shift lever 45121 rotates inward, the first reset member 4514 is stretched. After the external operation handle withdraws, the first reset member 4514 contracts and pulls the return lever 45122 to drive the shift lever 45121 to return to its original position. The rotational stroke of the return lever 45122 in the latter way is larger, avoiding excessive directional blocking force on the insertion of the external operation handle by the return lever 45122.

[0150] Optionally, the connection angle between the abutting rod 45131 and the driving rod 45132 is an acute angle, and in the direction away from the abutting rod 45131, the width of the driving rod 45132 gradually decreases; the linkage rod 4513 further includes a counterweight 45133, and the counterweight 45133 is disposed at the connection of the abutting rod 45131 and the driving rod 45132.

[0151] Wherein, the significance of the connection angle between the abutting rod 45131 and the driving rod 45132 being an acute angle in this embodiment is that the projection of the center of the driving rod 45132 in the vertical direction is located on the abutting rod 45131. In this way, the linkage rod 4513 has a tendency to rotate towards the first mounting seat 4511 as a whole under the action of gravity. Its function is that after the middle door is opened, the linkage rod 4513 returns to its original position under the action of gravity, and the abutting rod 45131 automatically falls back onto the first mounting seat 4511 without setting other auxiliary reset members.

[0152] In addition, based on the above, the counterweight head 45133 increases the overall gravity of the linkage rod 4513, which is more conducive to the outward rotation of the drive rod 45132.

[0153] Optionally, the middle door interlock assembly 451 further includes a rotating rod seat 4515, a rotating rod shaft 4516, a first rotating rod 4517, a second rotating rod 4518, a door latch 4519, a linkage member 4510, and a door lock rod 45101; the linkage member 4510 is movably arranged on the operating mechanism 42 and is connected to the longitudinal beam 412; the rotating rod seat 4515 is arranged on the operating mechanism 42, the rotating rod shaft 4516 is rotatably arranged on the rotating rod seat 4515, the first rotating rod 4517 is arranged at one end of the rotating rod shaft 4516, one end of the first rotating rod 4517 is connected to the linkage member 4510, the second rotating rod 4518 is arranged at the other end of the rotating rod shaft 4516, and one end of the door lock rod 45101 is connected to one end of the second rotating rod 4518; the door latch 4519 is arranged on the middle door. When the terminal post 411 is in the working state and the middle door is in the closed state, the door lock rod 45101 acts on the door latch 4519 to prevent the middle door from opening, and the door latch 4519 abuts against the end of the drive rod 45132 away from the abutting rod 45131 to enable the drive rod 45132 to avoid the blocking rod 45121. If the longitudinal beam 412 rotates to make the terminal post 411 transfer from the working state to the isolation state, the linkage member 4510 drives the first rotating rod 4517 to rotate and links the second rotating rod 4518, and the door lock rod 45101 is separated from the door latch 4519 by the second rotating rod 4518 to allow the middle door to open.

[0154] Among them, this embodiment defines the situation where the middle door is allowed to open. In this embodiment, the door latch 4519 is U-shaped as a whole, and both ends of the door latch 4519 are connected to the inner side of the middle door. Among the above, the middle door abuts against the driving rod 45132 through the side of the door latch 4519 away from the middle door. The projections of the first rotating rod 4517 and the second rotating rod 4518 in the horizontal direction are in a cross relationship, and preferably perpendicular to each other. According to the prior art, the linkage 4510 is connected to the longitudinal beam 412 through a working state switching device, which will not be elaborated here. The bottom end of the door lock rod 45101 is hinged to one end of the second rotating rod 4518, and the top end is used to interact with the door latch 4519. Specifically, the linkage 4510 is located on the side of the isolation motor 414 where the manual operation contact 4140 is provided. The linkage 4510 moves horizontally. With the pole 411 in the working state as the initial state, at this time, the linkage 4510 is in the leftmost position, and the top end of the door lock rod 45101 is inserted into the door latch 4519. At this time, the middle door is not allowed to be opened. When the pole 411 rotates towards the isolation position, the rotation of the longitudinal beam 412 drives the linkage 4510 to move to the right through the working state switching device. At this time, the first rotating rod 4517 and the second rotating rod 4518 rotate clockwise, and the door lock rod 45101 moves downward and disengages from the door latch 4519. In this way, the middle door is allowed to be opened. Conversely, the linkage 4510 moves from right to left, and the door lock rod 45101 moves upward and is inserted into the door latch 4519 again. In addition, to achieve the smoothness of the up and down movement of the door lock rod 45101, the door lock rod 45101 can be selectively inserted into the operating mechanism 42 movably.

[0155] Optionally, participate Figure 28 , the middle door interlock assembly 451 further includes a locking member 45102; the vehicle frame 43 is locked and positioned in the installation cavity; one end of the locking member 45102 is hinged to the other end of the second rotating rod 4518, and the second rotating rod 4518 rotates to drive the locking member 45102 to move away from or close to the vehicle frame 43; when the pole 411 is in the working state, the locking member 45102 acts on the vehicle frame 43 to prevent the unlocking between the vehicle frame 43 and the installation cavity. When the pole 411 is in the isolation state, the locking member 45102 releases the action on the vehicle frame 43.

[0156] Specifically, one end of the locking member 45102 is hinged to the other end of the second rotating rod 4518, and the second rotating rod 4518 rotates to drive the locking member 45102 to move away from or close to the positioning member 442; when the pole 411 is in the working state, the locking member 45102 acts on the positioning member 442 to lock the positioning member 442 from withdrawing from the first positioning hole. When the pole 411 is in the isolation state, the locking member 45102 releases the action on the positioning member 442.

[0157] Among them, the locking member 45102 can be selected as a rod. The top end of the locking member 45102 is hinged to the other end of the second rotating rod 4518, and the bottom end is used to interact with the positioning member 442 of the positioning assembly 44. The locking member 45102 also moves up and down following the rotation of the second rotating rod 4518. In contrast to the locking member 45102 is the aforementioned door lock rod 45101. The two are respectively located at the movement of the second rotating rod 4518 to achieve fire protection reverse. Therefore, it is known in this embodiment that after the vehicle frame 43 enters the working position, then the middle door is closed. At this time, the pole column 411 in the isolation position rotates to the working position, and the door lock rod 45101 moves upward into the door buckle 4519, preventing the opening of the middle door; the locking member 45102 acts downward on the positioning member 442 on the nearest side, preventing the positioning member 442 from contracting towards the middle of the operating mechanism 42, ensuring that the vertical rotation isolating vacuum circuit breaker 40 is not easily displaced in the installation cavity; specifically, the positioning member 442 is provided with an insertion opening as described above, and the locking member 45102 is inserted downward into the notch to prevent the positioning member 442 from contracting towards the inside of the operating mechanism 42.

[0158] Optionally, referring to Figure 28 , the rotating rod seat 4515 is provided with a guiding hole 45151; the middle part of the locking member 45102 is passed through the guiding hole 45151.

[0159] Among them, referring to the aforementioned door lock rod 45101 which can be optionally inserted into the operating mechanism 42 movably to ensure the stability of the up and down movement. The locking member 45102 in this embodiment also refers to the door lock rod 45101. The difference is that the guiding hole 45151 is provided on the rotating rod seat 4515, and the locking member 45102 is passed through the guiding hole 45151.

[0160] Optionally, referring to Figure 27 , the vertical rotation isolating vacuum circuit breaker 40 further includes a grounding mechanism 46. The grounding mechanism 46 includes a first support seat 461, a grounding blocking rod 462, a blocking plate 463 and a blocking rod 464; the first support seat 461 is arranged on the cabinet body 10, the grounding blocking rod 462 is movably arranged on the first support seat 461 and is connected to the grounding switch 90, and the operating hand rod controls the grounding switch 90 to trip or close through the grounding blocking rod 462; the blocking plate 463 is movably arranged on the operating mechanism 42, one end of the blocking plate 463 is hinged to the other end of the first rotating rod 4517, and the first rotating rod 4517 rotates to drive the blocking plate 463 to move. When the pole column 411 is in the working state, the blocking plate 463 enters the movement path of the grounding blocking rod 462 to prevent the grounding switch 90 from closing. When the pole column 411 is in the isolation state, the blocking plate 463 withdraws from the movement path of the blocking plate 463 to allow the grounding switch 90 to close; the blocking rod 464 is movably arranged on the first support seat 461 and one end of it is connected to the grounding switch 90. When the grounding switch 90 is closed, the blocking rod 464 blocks in the rotation path of the blocking rod 45121 to prevent the rotation of the blocking rod 45121.

[0161] Among them, the grounding switch 90 belongs to the prior art, and when the vertical rotation indoor AC metal-enclosed switchgear is in the isolated state, the grounding switch 90 needs to be grounded so that maintenance personnel can enter the site; conversely, it is not allowed during the working state. In this embodiment, the grounding blocking rod 462 is used to connect to the grounding switch 90 to operate the opening and closing of the grounding switch 90 under the action of the grounding operating handle, and the grounding blocking rod 462 is arranged to be movable in the up and down directions. The grounding switch 90 is entirely located on the right side of the middle door interlock assembly 451.

[0162] According to the foregoing, it can be known that the state description of this embodiment is: when the baffle 463 is in the rightmost position, it enters the movement path of the grounding blocking rod 462, and when it is in the leftmost position, it exits the movement path of the grounding blocking rod 462. When the first rotating rod 4517 rotates clockwise, the vertical rotation isolating vacuum circuit breaker 40 is rotated into the isolated state. At this time, the baffle 463 moves from the leftmost position to the rightmost position, and the baffle 463 exits the movement path of the grounding blocking rod 462. In this way, the grounding blocking rod 462 can move up and down and interact with the grounding switch 90. Conversely, when the vertical rotation isolating vacuum circuit breaker 40 is in the working state, the baffle 463 enters the movement path of the grounding blocking rod 462. In this embodiment, the baffle 463 is located above the grounding blocking rod 462.

[0163] In addition, to prevent misoperation of the manual operating contact 4140 when the grounding switch 90 is closed to rotate the pole column to the working state, in this embodiment, the blocking rod 464 moves up and down following the grounding switch 90. When the grounding switch 90 is closed, the top of the blocking rod 464 enters the rotation path of the stop rod 45121 to prevent the stop rod 45121 from rotating inward, thereby preventing the external operating handle from being combined with the manual operating contact 4140. In this embodiment, a stop block for abutting against the stop rod 45121 is provided at the top of the stop rod 45121. Of course, as described above, the blocking fork 4512 further includes a return rod 45122, so the blocking rod 464 of this embodiment can abut against the return rod 45122. On the contrary, when the grounding switch 90 is opened, the blocking rod 464 moves downward to vacate the rotation path of the return rod 45122.

[0164] Optionally, the grounding mechanism 46 further includes a second support seat 465, and a through hole is provided on the second support seat 465, and the baffle 463 slidably passes through the through hole.

[0165] Among them, the second support seat 465 is arranged in the operating mechanism 42. The baffle 463 is composed of a vertical plate, an upper horizontal plate and a lower horizontal plate to form a U-shaped structure. In this embodiment, the length of the lower horizontal plate is less than that of the upper horizontal plate. The second support seat 465 is provided with a U-shaped through hole, and the U-shaped through hole is horizontally arranged. The lower horizontal plate is used to block the grounding blocking rod 462.

[0166] Optionally, the closing and opening interlock assembly 452 includes a second mounting seat 4521, a blocking crank arm 4522, and a linkage blocking member 4523; the second mounting seat 4521 is disposed on the operating mechanism 42, the blocking crank arm 4522 includes a blocking arm 45221, the blocking arm 45221 is rotatably disposed on the second mounting seat 4521 and rotates in the horizontal direction, and one end of the blocking arm 45221 is disposed on one side of the external free end, the linkage blocking member 4523 is disposed on the operating mechanism 42 and connected to the driving mechanism 413, and the linkage blocking member 4523 rotates in the vertical direction; when the pole column 411 is closed, the driving mechanism 413 drives the linkage blocking member 4523 into the rotation radius of the blocking arm 45221 to prevent one end of the blocking crank arm 4522 located on one side of the external free end from rotating in the direction of the manual operation contact 4140.

[0167] Wherein, the middle part of the linkage blocking member 4523 is on the operating mechanism 42, and the middle part of the blocking crank arm 4522 is rotatably disposed on the second mounting seat 4521. The linkage blocking member 4523 is of an L-shaped structure. One end of the linkage blocking member 4523 can be connected to the driving mechanism 413 through a working state switching device or an existing connecting rod structure, and is specifically connected to the rotating shaft 4131 of the driving mechanism 413, which will not be elaborated here. In addition, one end of the blocking arm 45221 and one end of the aforementioned blocking rod 45121 are both at the same horizontal height as the external free end, and the vertical distances from both to the external free end are equal. Thus, it can be understood that each of these two ends blocks half of the position of the external free end. Therefore, only when both of these two ends are unlocked and opened can the external operation handle be engaged with the external free end.

[0168] The key point of this embodiment is that when the pole column 411 is in the closed state, at this time the other end of the linkage rod 4513 blocks the rotation path of the other end of the blocking crank arm 4522. In this way, the external operation handle is blocked by one end of the blocking crank arm 4522 and cannot be combined with the external free end of the manual operation contact 4140, effectively preventing misoperation. On the contrary, when the pole column 411 is switched to the open state, the linkage rod 4513 rotates upward and leaves the rotation path of the blocking crank arm 4522. At this time, when the external operation handle acts on one end of the blocking crank arm 4522 close to the blocking rod 45121, the blocking crank arm 4522 can rotate inward.

[0169] In summary, the condition for the external operation handle to be combined with the external free end is that the pole column 411 is open, the middle door is closed, and the earthing switch 90 is closed. Only then can the external operation handle push inwards the blocking arm 45221 and the blocking rod 45121 to be engaged with the external free end. In addition, the blocking crank arm 4522 further includes a vertical rod 45222, the vertical rod 45222 is disposed at the end of the blocking crank arm 4522 far from the blocking rod 45121 and extends upward, and its function is to abut against a sub-board of the L-shaped linkage blocking member 4523.

[0170] The closing and opening interlock assembly 452 further includes a second reset member 4524, which is disposed on the second mounting seat 4521 and acts on the side of the blocking arm 45221 close to the manual operation contact 4140; during the process that the external operation handle abuts against the blocking arm 45221 and docks with the external free end, the blocking arm 45221 rotates towards the manual operation contact 4140 and deforms the second reset member 4524. During the process that the external operation handle withdraws and releases the docking with the manual operation contact 4140, the second reset member 4524 releases and pushes the blocking arm 45221 to reset.

[0171] Wherein, the second reset member 4524 is a tension spring. One end of the tension spring is connected to the second mounting seat 4521, and the other end is connected to the end of the blocking arm 45221 close to the linkage blocking member 4523. When the end of the blocking arm 45221 close to the blocking rod 45121 is pushed inward by the external operation handle and rotates inward, at this time, the end of the blocking arm 45221 close to the linkage blocking member 4523 rotates outward, and at this time the tension spring is stretched. After the external operation handle is withdrawn, the tension spring pulls back and the blocking arm 45221 resets. More preferably, an anti-rotation member is provided on the second mounting seat 4521. The anti-rotation member is disposed on the second reset member 4524 and on the side of the blocking arm 45221 close to the isolating motor 414. The anti-rotation member is disposed at the end of the blocking arm 45221 close to the linkage blocking member 4523, and is used to prevent the end of the blocking arm 45221 close to the linkage blocking member 4523 from rotating too much inward when the second reset member 4524 pulls the blocking arm 45221 to reset.

[0172] Here, a brief description is added to clarify the principle of the forward and reverse rotation of the longitudinal beam 412. The isolating motor 414 is a forward and reverse rotation motor, and the driving component 130 is driven by the isolating motor 414. The driving component 130 is preferably a lead screw assembly. Specifically, the lead screw assembly includes a lead screw and a lead screw platform. The lead screw is disposed in the operating mechanism 42 (the isolating motor 414 drives the lead screw to rotate bidirectionally), and its axial direction is perpendicular to the axial direction of the longitudinal beam 412. The lead screw platform is disposed on the lead screw. A rotating fork 170 is provided at one end of the longitudinal beam 412 located in the operating mechanism 42, and the lead screw platform is provided with a plug rod inserted into the rotating fork 170, so as to realize the three-dimensional conversion from linear motion to rotation; in addition, the lead screw platform is connected to the guiding support 31. The linkage logic here is that since the pole column 411 passes through the valve 38 when switching between the isolating state and the working state, the valve 38 and the pole column 411 are linked to open or close. The valve 38 and the pole column 411 are driven by the same driving component to achieve the effect of reducing the component setting, reducing the space occupation. The above technologies are all prior arts and will not be elaborated here.

[0173] It should be noted that the aforementioned middle door interlock assembly 451, the closing and opening interlock assembly 452, and the grounding mechanism 46 achieve mechanical interlocking, which not only improves the reliability of the system but also realizes integration by integrating various structures, reducing space occupation.

[0174] Optionally, referring to Figure 1 and Figure 30 , it further includes a channel assembly 70. The channel assembly 70 includes a cover body 71 and a connecting member 72; a channel outlet is provided on the cabinet body 10; the connecting member 72 is configured as an extension member, and a second heat dissipation hole 710 is provided on the cover body 71. At least one side of the cover body 71 is connected to the edge of the channel outlet through the connecting member 72; when the cover body 71 is subjected to a pressure impact from the inside to the outside inside the channel outlet, the connecting member 72 deforms or displaces to cause the cover body 71 to make a flipping motion away from the channel outlet.

[0175] Among them, the cover body 71 in this embodiment can be a shielding plate or a polyhedron with a regular quadrilateral outer contour. This embodiment takes the regular quadrilateral polyhedron as an example. The channel outlet is provided at the top of the cabinet body 10. The number of the second heat dissipation holes 710 can be multiple, and the multiple second heat dissipation holes 710 can be selectively arranged at any position on the cover body 71. In this embodiment, a cavity with a downward opening is provided at the bottom of the cover body 71, and the cavity covers the channel outlet to block the channel outlet.

[0176] Importantly, the cover body 71 is connected to the edge of the channel outlet through the connecting member 72. Also, due to the extension member characteristic of the connecting member 72 itself, it has freedom degrees relative to the channel outlet. For example, the directions of the freedom degrees at least include the directions parallel or perpendicular to the channel outlet.

[0177] In this embodiment, a second heat dissipation hole 710 for heat dissipation is provided on the cover body 71, and the cover body 71 is connected to the edge of the channel of the channel through the connecting member 72. Additionally, based on the extensibility of the connecting member 72, the freedom degrees provided by the extensibility enable the cover body 71 to move away from the channel outlet when the pressure inside the channel outlet increases, providing more pressure relief space for the channel outlet. Moreover, the channel outlet serves as both an air outlet and a pressure relief outlet, and the two channels do not need to separately occupy the space inside the cabinet body 10 for layout, effectively compressing the volume of the cabinet body 10.

[0178] Optionally, the connecting member 72 includes a plastic bolt, and the plastic bolt acts on the cover body 71 to connect the cover body 71 to the edge of the channel outlet.

[0179] Among them, a plastic bolt (preferably nylon, not shown in the figure) passes through the side plate of the cover body 71 and is screwed to the edge of the channel outlet. The plastic bolt has certain deformation characteristics. When the pressure inside the channel outlet increases, it pushes the cover body 71 outwards. At this time, the plastic bolt has deformation characteristics for adaptive adjustment, or the plastic bolt loosens and displaces. As a result, a gap for pressure relief appears between the cover body 71 and the edge of the channel outlet. At the same time, the deformation or loosening of the plastic bolt causes the corresponding side of the cover body 71 to displace, thereby relieving the pressure from the channel outlet and avoiding the problem that the cover body 71 is deformed due to excessive force. Of course, as mentioned above, at least one side of the cover body 71 is connected to the edge of the channel outlet through the connecting member 72. In the actual application process, in addition to the solution where the connecting member 72 is arranged on one side for connection, it is also possible to select two or more sides to be connected and fixed to the channel outlet through the connecting member 72. It can be known that when each side connected to the channel outlet through the connecting member 72 is subjected to internal force, a gap will be formed with the edge of the channel outlet. The more gaps there are, the stronger the pressure relief ability.

[0180] Optionally, the connecting member 72 further includes a flexible strip 721. One end of the flexible strip 721 is a relatively free end; the cover body 71 includes a first side and a second side arranged opposite to each other. The first side is connected to the edge of the channel outlet through a plastic bolt, and the relatively free end of the flexible strip 721 is connected to the second side, and the other end is connected to the edge of the channel outlet.

[0181] Among them, the flexible strip 721 can be selected as a thin metal strip, such as an aluminum alloy strip, which is required to be deformable under a specific acting force, so as to change the position of the relatively free end. Otherwise, the flexible strip 721 can be selected as a nylon strip, etc.

[0182] Example of the use of the flexible strip 721: A plurality of flexible strips 721 are arranged at intervals along the length direction of the second side edge at the lower part of the cover body 71. Specifically, the first side edge and the edge of the channel outlet are preferably fixedly connected by plastic bolts. Under normal circumstances, the lower side edge of the cover body 71 preferably fits the edge of the channel outlet, and the second heat dissipation holes 710 dissipate heat outward. Similarly, the second heat dissipation holes 710 can also be used for normal pressure relief. Particularly, if the pressure inside the channel outlet increases instantaneously or continuously, the internal air pressure can push the cover body 71 away from the channel outlet from the inside out. At this time, in addition to the aforementioned plastic bolts being displaced, the relative free ends of the flexible strips 721 also move with the cover body 71. Therefore, gaps are generated between the first side edge and the second side edge and the edge of the channel outlet. This gap also increases the internal space of the channel device and provides a pressure reduction space. If the cover body 71 and the channel outlet are in an up-and-down position relationship, after the pressure relief is completed, the cover body 71 can automatically fall back under the action of gravity or return to its position under the push of an external force. Additionally, another function of the flexible strip 721 is that if the plastic bolts fall off, the flexible strip 21 can form a pull on the cover body 71 to prevent the cover body 71 from being pushed away too far.

[0183] In other embodiments, the above-mentioned second side edge is connected to the edge of the channel outlet through the flexible strip 721. In other embodiments, the lower part of the regular tetrahedron polyhedron further includes a relatively arranged third side edge and a fourth side edge. The third side edge and the fourth side edge can be connected to the edge of the channel outlet through the flexible strip 721 or plastic bolts, and their solutions can be freely combined and are not limited here. Moreover, the first side edge, the second side edge, the third side edge, and the fourth side edge can also be connected to the edge of the channel outlet only through the flexible strip 721.

[0184] Optionally, the connecting member 72 further includes a fixing plate 722. One end of the flexible strip 721 on the second side of the cover body 71 away from the cover body 71 is connected to the edge of the channel outlet through the same fixing plate 722; or, a fixing plate 722 is arranged on the second side edge, and the second side edge is connected to the edge of the channel outlet through the fixing plate 722.

[0185] Among them, the fixing plate 722 is used to uniformly connect one end of the flexible strip 721 on the second side of the cover body 71, which is far away from the cover body 71, to one of its own sides, and is connected to the edge of the channel outlet through the fixing plate 722. The fixing plate 722 can be used as a connection contact surface with a larger area, so the reliability is higher compared to directly connecting one end of the flexible strip 721 to the edge of the channel outlet. Of course, in combination with the foregoing, if a set of opposite sides on the cover body 71 are connected to the edge of the channel outlet, regardless of whether there is a flexible strip 721 on the side, the side can be connected to the edge of the channel outlet through the fixing plate 722. Therefore, the fixing plate 722 can also be provided on the first side in this embodiment. The fixing plate 722 is arranged horizontally, and a plurality of through holes are arranged along the length direction of the fixing plate 722 on the first side. The plastic bolts pass through the through holes and are screwed to the edge of the channel outlet. The contact surface between the fixing plate 722 on the first side and the edge of the channel outlet is larger, improving the connection sealing performance. In addition, the plastic bolts acting on the fixing plate 722 prevent the deformation and damage of the cover body 71.

[0186] Optionally, the fixing plate 722 connected to the flexible strip 721 is fixedly connected to the edge of the channel outlet through a rigid bolt.

[0187] Among them, a plurality of through holes are arranged along the length direction of the fixing plate 722 in this embodiment. The rigid bolts (preferably made of metal, not shown in the figure) pass through the through holes and are screwed to the edge of the channel outlet. It can be known from the foregoing that the flexible strip 721 can pull the cover body 71. Therefore, the fixing plate 722 connected to the flexible strip 721 needs to form a firm connection with the edge of the channel outlet. Thus, the fixing plate 722 in this embodiment is connected to the edge of the channel outlet through a rigid bolt.

[0188] Optionally, the connecting member 72 further includes an extension plate 723; the flexible strips 721 are all connected to the side of the cover body 71 through the same extension plate 723.

[0189] Among them, the extension plate 723 is arranged outside the lower side of the cover body 71 (in combination with the above embodiment, the extension plate 723 is arranged on the second side). The flexible strip 721 is connected to the side of the cover body 71 through the extension plate 723. The extension plate 723 can be made to fit the peripheral edge of the channel outlet to ensure the sealing performance between the lower side of the cover body 71 and the edge of the channel outlet under normal pressure conditions.

[0190] Of course, the foregoing flexible strip 721, fixing plate 722 and extension plate 723 can be integrally provided. Assuming that the three are made of metal, a plurality of through slots are stamped between the fixing plate 722 and the extension plate 723, and a connecting strip with a very small width is formed between adjacent through slots. The connecting strip forms the above-mentioned flexible strip 721. Preferably, the width of the connecting strip is 1 mm - 5 mm, and the length is 1 nm - 10 nm.

[0191] Optionally, the cover 71 includes a cover plate 711 and a plurality of side plates 712; the plurality of side plates 712 are arranged around the side of the cover plate 711, and the side plates 712 are connected to the edge of the channel outlet through a connecting member 72; the second heat dissipation holes 710 are provided on the side plates 712.

[0192] Among them, the above-mentioned regular quadrilateral polyhedron is composed of the cover plate 711 and four side plates 712 of this embodiment. The above-mentioned side refers to the side below the side plate 712. Since the cover plate 711 faces the channel outlet directly, the second heat dissipation holes 710 of this embodiment are provided on the side plates 712, effectively avoiding external dust and other impurities from directly entering the channel outlet.

[0193] Optionally, it further includes a conductive plate 100. Support insulators 80 and inductance devices 50 are oppositely arranged on the inner wall of the cabinet body 10; the conductive plate 100 includes a flat plate 101 and two mounting plates 102 extending in the same direction arranged at both ends of the flat plate 101; the two mounting plates 102 are respectively mounted on the inductance device 50 and the support insulator 80, the two mounting plates 102 are located below the flat plate 101, and a lower static contact 110 for connecting with the pole column 411 is provided on the top of the flat plate 101.

[0194] Among them, it can be known that moving contacts are respectively arranged at both ends of the aforementioned pole column 411. In the working state, the moving contact (upper moving contact) at the top of the pole column 411 is engaged with the contact box device 20, and the moving contact (lower moving contact) at the bottom of the pole column 411 is engaged with the inductance device 50. The inductance device 50 includes an instrument transformer. It is described above that the number of the pole columns 411 is three, and correspondingly, the number of the instrument transformers is also three.

[0195] Actually, the flat plate 101 of this embodiment and the two mounting plates 102 extending in the same direction arranged at both ends of the flat plate 101 form a U-shaped conductive plate 100. The mounting plates 102 are specifically provided for connecting with the support insulator 80 and the instrument transformer, improving the overall installation reliability of the conductive plate 100.

[0196] Optionally, it further includes a cable mounting plate 120; the cable mounting plate 120 is arranged on the side of the inductance device 50 away from the cabinet body 10, and one end of the cable mounting plate 120 is arranged towards the bottom of the cabinet body 10 and extends to directly below the inductance device 50.

[0197] Among them, the mutual inductor is used for connecting an external cable, and in this embodiment, it is connected to the external cable through the cable mounting plate 120. Specifically, two bends are formed in the middle of the cable mounting plate 120, so that there are two parallel plate surfaces at both ends of the cable mounting plate 120. The cable mounting plate 120 is arranged from top to bottom in the cabinet body 10. The upper plate surface is connected to the mutual inductor, and the lower plate surface is arranged directly below the mutual inductor. The significance of arranging the lower plate surface directly below the mutual inductor is that a grounding mechanism 46 is arranged obliquely below the opposite side of the mutual inductor in this embodiment. Therefore, the lower plate surface of the cable mounting plate 120 avoids the area directly below the mutual inductor, so that the grounding mechanism 46 can be arranged as close as possible to the mutual inductor in the horizontal direction, thereby reducing the size of the cabinet body 10 in the front-back direction, and further realizing the miniaturization of the vertical-rotation indoor AC metal-enclosed switchgear. In addition, the cable mounting plate 120 is connected to the contact switch 160 through a metal plate.

[0198] Optionally, referring to Figures 33 - 35 , it further includes an energy storage mechanism 140; the operating mechanism 42 includes a housing 421 and two partition plates 422. The two partition plates 422 are arranged at intervals along the length direction of the housing 421 to divide the interior of the housing 421 into a first space, a second space, and a third space arranged in sequence. An output hole 4211 for communicating the second space with the outside is provided on the side wall of the housing 421; the energy storage mechanism 140 is arranged at the bottom inside the housing 421 and at least penetrates through the third space and the second space in the length direction of the housing 421. One end of the longitudinal beam 412 penetrates through the output hole 4211; the driving assembly 130 is arranged inside the housing 421 and at least penetrates through the third space and the second space in the length direction of the housing 421. The driving assembly 130 is located above the output hole 4211 and acts on the longitudinal beam 412; the energy storage mechanism 140 and the rotating shaft 4131 are rotatably arranged on the two partition plates. The connecting rod 4132 passes through the output hole 4211 to extend outside the housing 421. The rotating shaft 4131 is located between the driving assembly 130 and the output hole 4211, and the rotating shaft 4131 is located below the driving assembly 130.

[0199] Among them, the purpose of this embodiment is to carry out modular layout inside the operating mechanism 42, so as to reduce the overall volume of the operating mechanism 42 and realize the miniaturization of the vertical-rotation indoor AC metal-enclosed switchgear. For this embodiment, the spatial structure is optimized in this embodiment to facilitate the operator to observe the movement of the pole column 411. In addition, each component tends to be arranged horizontally, so that the vertical-rotation indoor AC metal-enclosed switchgear can have a smaller longitudinal dimension.

[0200] Specifically, the energy storage mechanism 140 generally includes an energy storage motor 141 and an energy storage transmission component 142. The energy storage motor 141 and the energy storage transmission component 142 are connected to each other and are separately arranged in the third space and the second space. The energy storage transmission component 142 acts on the driving mechanism 413. This connection relationship is a prior art and will not be elaborated here. Importantly, the energy storage motor 141 and the energy storage transmission component 142 are horizontally arranged at the bottom of the housing 421. The bottom end of the energy storage spring 150 is connected to one end of the transmission component 142 and extends longitudinally. The upper end of the energy storage spring 150 is connected to the inside of the housing 420. It is known that the energy storage spring 150 is used to store energy for the closing of the driving mechanism 413.

[0201] Particularly, it should be noted that the top end of the linkage rod 4513 of the present invention passes through and protrudes from the top of the housing 421. The door latch 4519 acts on the part of the linkage rod 4513 located outside the housing 421. A step is provided at the top of the housing 421 near the pole 411. The guiding support 31, the fixed support 32, the first crank 33, the second crank 34, the output shaft 35 and the third crank 36 of the valve device 30 are arranged in this step. Importantly, the guiding support 31 is an L-shaped bent plate. A limiting groove is provided along the length of the horizontal plate of the L-shaped bent plate. The L-shaped bent plate is limited on the housing 421 by inserting a T-shaped block into the limiting groove. It should be noted that the L-shaped bent plate can slide along the length direction (left and right) of the housing 421. Therefore, it can be known that the aforementioned bolt is inserted into the driving groove 611, and the bolt and the connecting slide base 601 can be separated directly. That is, when the vertical rotation isolating vacuum circuit breaker 40 is in the working position, the bolt is inserted into the driving groove 611; when the vertical rotation isolating vacuum circuit breaker 40 is in the maintenance position, the bolt disengages from the driving groove 611. In the foregoing, the stroke conversion seat 39 is arranged on one side of the guiding support 31. To avoid the stroke conversion seat 39 occupying extra space, in this embodiment, the stroke conversion seat 39 can be used as the side plate of the housing 421 near the guiding support 31. In this way, the stroke conversion seat 39 serves as a part of the housing 421 and can also be used to act on the sliding pin 390.

[0202] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions formed by any combination of the above technical features. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
