[0027] The present invention provides a longitudinal rotation isolating vacuum circuit breaker, which aims to solve the above technical problems in the prior art.

[0028] The technical solution of the present invention and how the technical solution of the present invention solves the above-mentioned technical problems are described in detail below with specific embodiments.

[0029] The embodiment of the present invention provides a longitudinal rotation isolation vacuum circuit breaker product, the structural schematic diagram of the longitudinal rotation isolation vacuum circuit breaker product is as follows Figure 1 and Figure 2 As shown, it includes: a bracket 10, an operating mechanism 20, a pole assembly 30 and a sensing assembly 40; the operating mechanism 20 includes a housing 21, an opening and closing linkage mechanism 22, a shift member 23 and a grounding switch linkage member 24; the pole assembly 30 is rotatably arranged on the bracket 10 and the housing 21, and the sensing assembly 40 includes an action member 41, a closing confirmation sensor 42 and an opening confirmation sensor 43, and the closing confirmation sensor 42 and the opening confirmation sensor 43 are respectively arranged on the housing 21; the pole assembly 30 rotates and drives the action member 41 to act on the closing confirmation sensor 42 and the opening confirmation sensor 43 respectively to confirm the opening and closing status of the pole assembly 30.

[0030] In this embodiment, the open or closed state of the pole assembly 30 is confirmed by the interaction between the actuator 41 and the closing confirmation sensor 42 and the opening confirmation sensor 43. The confirmation of the opening and closing state can effectively prevent misoperation and improve the safety of the isolating vacuum circuit breaker.

[0031] Optionally, the action member 41 is movably arranged relative to the housing 21, and the movable circuit of the action member 41 is defined as a motion sensing path, and the closing confirmation sensor 42 and the opening confirmation sensor 43 act on the motion sensing path of the action member 41 respectively; wherein, when the pole assembly 30 rotates forward and reverse to close or open, the action member 41 is driven to reciprocate on the motion sensing path, and the action member 41 switches to act on the closing confirmation sensor 42 or the opening confirmation sensor 43 to confirm the closing or opening state of the pole assembly 30.

[0032] In the prior art, the pole assembly 30 rotates on the bracket 10 and the housing 21 and has a closed position (vertical) and an open position (horizontal), which will not be elaborated here.

[0033] It is understood that the pole assembly 30 drives the actuator 41 to move on the housing 21. When the pole assembly 30 is in the closed state, when the actuator 41 moves to the position of the closing confirmation sensor 42, the two sensors react and generate electrical feedback. Similarly, when the actuator 41 moves to the position of the opening confirmation sensor 43, the two sensors react and generate electrical feedback.

[0034] In the above, the sensor can be connected to an external indicator light or display system to display the closing or opening status of the disconnector.

[0035] To explain in more detail, in combination with the prior art, it can be seen that the pole assembly 30 includes a longitudinal beam 31, a three-phase pole 32, a screw group 33, a drive shaft 34 and a swivel fork 35; one end of the longitudinal beam 31 is rotatably set on the housing 21, and the other end is rotatably set on the bracket 10, the three-phase pole 32 is set on the longitudinal beam 31, and a plug-in opening 351 is set on one end of the swivel fork 35. One end of the swivel fork 35 is connected to the longitudinal beam 31, and the plug-in opening 351 is set in a direction away from the axis of the rotation axis of the longitudinal beam 31; the screw group 33 includes a screw 331 and a platform 332, the screw 331 rotates on the housing 21 and is set along the radial direction of the rotation axis of the longitudinal beam 31, and the platform 332 is movably set on the screw 331.

[0036] It is understood that the specific components of the pole assembly 30 and the operating mechanism 20, as well as the connections between them, are all prior art and will not be elaborated upon here. The length of the insertion opening 351 of the swivel fork 35 is perpendicular to the length of the longitudinal beam 31. Preferably, the drive shaft 34 is inserted into the opening of the insertion opening 351. In this embodiment, the drive shaft 34 is movably connected to the insertion opening 351. The rotation of the longitudinal beam 31 is driven by the linear motion of the drive shaft 34. This platform 332 can also be used to linearly drive other components. This is prior art and will not be elaborated upon here.

[0037] Optionally, the operating member 41 includes a sliding plate 411; the sliding plate 411 is movably arranged on the housing 21 and moves linearly on the housing 21, and the path of the linear motion of the sliding plate 411 is defined as a linear sensing path; the closing confirmation sensor 42 includes a linear closing microswitch group, the linear closing microswitch group includes a first linear closing microswitch 421, and the opening confirmation sensor 43 includes a linear opening microswitch group, the linear opening microswitch group includes a first linear opening microswitch 431; the first linear closing microswitch 421 is arranged on the housing 21 and is located at the bottom of the linear sensing path, and the first linear opening microswitch 431 is arranged on the housing 21 and is located on one side of the linear sensing path.

[0038] It should be noted that in this embodiment, an elastic contact is provided on the existing micro switch, and the elastic contact can be set in the linear sensing path of the sliding plate 411. When the sliding plate 411 moves back and forth, it can continuously switch back and forth between the first linear closing micro switch 421 and the first linear opening micro switch 431, so that the opening or closing state of the isolating switch can be electrically fed back.

[0039] Specifically, the sliding plate 411 is disposed on top of the platform 332. Specifically, the platform 332 passes through the top of the housing 21 and reaches the outside of the housing 21. The sliding plate 411 is then disposed outside the housing 21 and moves with the platform 332 to achieve relative movement relative to the housing 21. The first linear closing microswitch 421 is disposed at the bottom of the linear sensing path, corresponding to the bottom of the sliding plate 411 abutting against the first linear closing microswitch 421.

[0040] Optionally, the linear closing microswitch group also includes a second linear closing microswitch 422, and the linear opening microswitch group also includes a second linear opening microswitch 432; the second linear closing microswitch 422 and the second linear opening microswitch 432 are both arranged on the housing 21 and located on one side of the linear sensing path.

[0041] In this embodiment, the second linear closing micro switch 422 and the second linear opening micro switch 432 are added to complete the double-point confirmation of the opening and closing of the linear induction path isolating switch. The more confirmation points there are, the stronger the reliability of the confirmation device and the higher the safety.

[0042] In combination with the above, it should be noted that the setting position of the micro switch relative to the sliding plate 411 is not unique and can be adjusted according to the overall layout of the isolating vacuum circuit breaker. The micro switch can be selected to be set on one side, top or bottom of the sliding plate 411, etc. The setting is based on the requirement that the two can abut each other.

[0043] Optionally, the first linear opening microswitch 431 , the second linear opening microswitch 432 , and the second linear closing microswitch 422 are arranged in sequence along a linear induction path, and the first linear closing microswitch 421 is located between the second linear opening microswitch 432 and the second linear closing microswitch 422 .

[0044] For ease of description, in conjunction with existing technology, the disconnector is defined as opening when the pole assembly 30 rotates counterclockwise to a horizontal position, and closing when the pole assembly 30 rotates clockwise to a vertical position. The first linear opening microswitch 431, the second linear opening microswitch 432, and the second linear closing microswitch 422 are arranged sequentially from left to right along the linear sensing path.

[0045] Optionally, the sliding plate 411 includes a base plate 4111 and an abutment protrusion 4112 arranged on the base plate 4111; the base plate 4111 is connected to the pole assembly 30, and the first linear closing microswitch 421 is arranged below the base plate 4111, and the abutment protrusion 4112 acts on the linear closing microswitch group and the linear opening microswitch group respectively.

[0046] For example, the first linear closing micro switch 421 abuts against the bottom surface of the bottom plate 4111 , and the first linear opening micro switch 431 , the second linear opening micro switch 432 , and the second linear closing micro switch 422 abut against the abutting protrusion 4112 .

[0047] Preferably, the abutting protrusion 4112 is provided on one side of the top of the bottom plate 4111 , and the cross section between the two forms an L-shaped structure.

[0048] Optionally, the number of abutment protrusions 4112 is equal to the sum of the number of linear closing microswitch groups and the linear opening microswitch groups, and each linear closing microswitch group and each linear opening microswitch group are respectively provided to act on an independent abutment protrusion 4112 .

[0049] For example, the first linear opening micro switch 431 , the second linear opening micro switch 432 and the second linear closing micro switch 422 are respectively provided with three abutting protrusions 4112 . For the convenience of description, the three abutting protrusions 4112 are respectively named as protrusion one, protrusion two and protrusion three. Specifically, when the circuit breaker is in the open position, protrusions 1 and 2 abut against the first linear opening microswitch 431 and the second linear opening microswitch 432 in a one-to-one correspondence. At this time, protrusion 3 separates from the second linear closing microswitch 422, and the bottom plate 4111 separates from the first linear closing microswitch 421. When the circuit breaker is in the closed position, protrusion 3 abuts against the second linear closing microswitch 422, the bottom plate 4111 abuts against the first linear closing microswitch 421, protrusion 1 separates from the first linear opening microswitch 431, and protrusion 2 separates from the second linear opening microswitch 432, thereby realizing the switching induction of the isolating switch opening and closing. The significance of providing multiple abutting protrusions 4112 in this embodiment is to avoid the bottom plate 4111 from moving too long a distance, which is conducive to compressing the space of the isolating vacuum circuit breaker and realizing the miniaturization of the isolating vacuum circuit breaker.

[0050] Alternatively, if the linear closing microswitch group includes only the second linear closing microswitch 422, and the linear opening microswitch group includes only the first linear opening microswitch 431 or the first linear opening microswitch 431, two abutting protrusions 4112 can be provided as described above, with the two abutting protrusions 4112 switching between inductive opening and closing. Alternatively, only one abutting protrusion 4112 can be provided, and the second linear closing microswitch 422 and the first linear opening microswitch 431 (or the first linear opening microswitch 431) can alternately sense the abutting protrusion 4112.

[0051] Optionally, the action member 41 also includes an action plate 412; the action plate 412 is arranged on the pole assembly 30, and the synchronous pole assembly 30 rotates, defining the path of the rotation movement of the action plate 412 as a curved sensing path; the closing confirmation sensor 42 includes a curved closing microswitch group, and the curved closing microswitch group also includes a curved closing microswitch 423; the opening confirmation sensor 43 also includes a curved opening microswitch group, and the curved opening microswitch group includes a curved opening microswitch 433; the curved closing microswitch 423 and the curved opening microswitch 433 are respectively arranged on the housing 21 and are respectively located on the curved sensing path.

[0052] Exemplarily, one end of the action plate 412 is connected to the pole assembly 30, and the other end is a free end. The free end extends away from the rotation axis of the pole assembly 30. The curved closing microswitch 423 and the curved opening microswitch 433 of this embodiment are disposed along the path of the free end. More specifically, the action plate 412 is disposed on the longitudinal beam 31.

[0053] In addition, the curve closing micro switch 423 and the curve opening micro switch 433 can also be set on one side of the action plate 412. The position setting of the micro switches in this embodiment can be arranged according to the spatial area.

[0054] Optionally, the number of the action plates 412 is two, and the number of the curve closing micro switch 423 and the curve opening micro switch 433 are each one; One action plate 412 is used to act on the curve closing micro switch 423 , and the other action plate 412 is used to act on the curve opening micro switch 433 .

[0055] In conjunction with the foregoing, the angle of rotation between opening and closing the disconnector is 90°. In this embodiment, the curved closing microswitch 423 and the curved opening microswitch 433 are horizontally arranged symmetrically about the rotation center of the pole assembly 30. The longitudinal extensions of the two action plates 412 pass through the rotation center and form a 90° angle.

[0056] Specifically, the action state of the two action plates 412 is: when the disconnector is in the open state, one action plate 412 acts on the curve opening microswitch 433, and along the rotation direction of the pole assembly 30, the other action plate 412 is located between the curve opening microswitch 433 and the curve closing microswitch 423, and at the same time below the curve opening microswitch 433 and the curve closing microswitch 423. In this way, after the pole assembly 30 rotates 90° clockwise, the disconnector is in the closed state. At this time, the above-mentioned one action plate 412 is separated from the curve opening microswitch 433, and the other action plate 412 acts on the curve closing microswitch 423 to abut, thereby forming the induction of state switching.

[0057] Other settings for the number of action plates 412 also include: the number of action plates 412 is one, so that the position angle between the curve opening microswitch 433 and the curve closing microswitch 423 is 90°, thereby realizing the function of one action plate 412 acting on the curve opening microswitch 433 and the curve closing microswitch 423.

[0058] Based on this, the sliding plate 411, the first linear closing microswitch 421, the second linear closing microswitch 422, the first linear opening microswitch 431, and the second linear opening microswitch 432 form one confirmation group. The action plate 412, the curved opening microswitch 433, and the curved closing microswitch 423 form another confirmation group. This creates two confirmation groups, which can simultaneously provide signal confirmation and signal feedback, achieving multiple safety features.

[0059] Alternatively, see Figure 3-Figure 8The opening and closing linkage mechanism 22 is connected to the pole assembly 30 and is located in the shell 21. The stopper 23 is movably arranged in the shell 21. A handle channel is provided on the shell 21. The earthing switch linkage 24 is movably arranged in the shell 21 and is located on the handle channel. When the pole assembly 30 is in the closed state, it acts and limits the movement of the earthing switch linkage 24. After the stopper 23 is subjected to force, it moves to avoid outside the handle channel, and the external handle can enter the handle channel. When the pole assembly 30 is in the open state, the external handle exits the handle channel. The earthing switch linkage 24 moves toward the stopper 23 and acts and limits the movement of the stopper 23. The stopper 23 blocks the handle channel to prohibit the external handle from being inserted into the handle channel.

[0060] In this embodiment, the emphasis is on the interlocking between the opening and closing linkage mechanism 22, the shift member 23 and the grounding switch linkage member 24 to prevent misoperation.

[0061] In addition, according to the prior art, it is known that the isolating vacuum circuit breaker is installed in the cabinet of the switch cabinet, and the isolating vacuum circuit breaker can be pushed into or pulled out of the cabinet by pulling (not shown). What is important is that after the isolating vacuum circuit breaker is pushed into the cabinet, the grounding switch linkage 24 will be linked with the grounding switch in the cabinet.

[0062] In addition, after the isolating vacuum circuit breaker is pushed into the cabinet, one side of the shell 21 is flush with the outside of the cabinet, and the handle channel is provided on the side of the shell 21 flush with the cabinet so that the operating handle can be inserted into the handle channel from the outside.

[0063] Furthermore, while the opening and closing of the pole assembly 30 of this embodiment affects the linkage of the shift member 23 and the grounding switch linkage member 24, combined with the above, it can be seen that the sensing assembly 40 is also synchronized. The sensing assembly 40 provides status confirmation for the opening and closing status of the pole assembly 30 of this embodiment, thereby ensuring the safety of operation.

[0064] Optionally, the opening and closing linkage mechanism 22 is driven by the pole assembly 30 to rotate, and the rotation path of the opening and closing linkage mechanism 22 includes the opening position and the closing position, and the moving path of the stop member 23 is provided with a blocking position and an avoidance position; the moving path of the grounding switch linkage 24 has an overlapping area with the moving paths of the opening and closing linkage mechanism 22 and the stop member 23; wherein, when the opening and closing linkage mechanism 22 is in the closing position, it enters the moving path of the grounding switch linkage 24, and the opening and closing linkage mechanism 22 limits the movement of the grounding switch linkage 24 on the housing 21 to prevent the external grounding switch from closing, and the grounding switch linkage 24 makes way for the stop member 23 The movable path, the shifting member 23 located in the blocking position moves to the avoidance position for avoidance, and the external handle can enter the handle channel; when the opening and closing linkage mechanism 22 is in the opening position, it disengages from the movable path of the grounding switch linkage 24 to release the grounding switch linkage 24, and the external handle exits the handle channel, and the shifting member 23 located in the blocking position moves to the avoidance position, and the grounding switch linkage 24 is operated to enter the movable path of the shifting member 23 and link the external grounding switch to close, and the grounding switch linkage 24 blocks the moving path of the shifting member 23 to limit the shifting member 23 to the avoidance position, and the shifting member 23 located in the avoidance position blocks the handle channel to prohibit the external handle from being inserted into the handle channel.

[0065] For example, the housing 21 has an inner cavity. The opening / closing linkage mechanism 22 and the stopper 23 are disposed within the inner cavity. According to regulations for the use of high-voltage equipment, the grounding switch cannot be closed when the disconnector is not open; nor can the operating handle enter the handle passage and operate the disconnector to close when the grounding switch is not open. As described above, the opening / closing linkage mechanism 22 has an opening position and a closing position. When the opening / closing linkage mechanism 22 is in the closing position (i.e., the disconnector is closed), the opening / closing linkage mechanism 22 enters the moving path of the grounding switch linkage 24, restricting its movement or locking it to prevent it from operating the grounding switch to close. Conversely, when the opening / closing linkage mechanism 22 is in the opening position (i.e., the disconnector is open), the restriction or lock on the grounding switch linkage 24 is released, allowing the grounding switch linkage 24 to resume movement and close the grounding switch.

[0066] In the above description, when no external force is applied, the stopper 23 is in the blocking position. When the grounding switch linkage 24 operates the grounding switch to close, it moves into the path of the stopper 23, blocking the movement of the stopper 23 from the blocking position to the avoidance position. In the blocking position, the stopper 23 blocks the handle passage, thereby preventing the operating handle from entering the passage and closing the disconnector. Conversely, when the grounding switch linkage operates the grounding switch to open, the grounding switch linkage 24 moves out of the way of (i.e., does not enter) the path of the stopper 23. The stopper 23 can move from the blocking position to the avoidance position, clearing the handle passage. At this point, the operating handle can enter the passage and close the disconnector.

[0067] Furthermore, the grounding switch linkage member 24 overlaps with the movable paths of the opening and closing linkage member mechanism 22 and the shift member 23, respectively, thereby achieving an interlocking effect among the three.

[0068] In other words, the grounding switch linkage 24 can be slidably arranged on the housing 21. According to the above, the grounding switch linkage 24 is restricted by the opening and closing linkage mechanism 22. It can be clearly known that whether the grounding switch linkage 24 can enter the movable path of the stopper 23 depends on the limitation of the grounding switch linkage 24 by the linkage plate assembly 221. When the opening and closing linkage mechanism is in the closing position, the linkage plate assembly 221 limits the movement of the grounding switch linkage 24, that is, limits the operation of closing the grounding switch. When the linkage plate assembly 221 is in the opening position, the linkage plate assembly 221 releases the movable path of the grounding switch linkage 24, and the grounding switch linkage 24 operates the grounding switch to close and enters the movable path of the stopper 23. The grounding switch linkage 24 prevents the stopper 23 from moving from the blocking position to the avoidance position, thereby blocking the handle channel and preventing the disconnector from closing. In this way, a forced interlock to prevent misoperation is achieved, preventing equipment damage or personal injury caused by misoperation during the operation, maintenance and inspection of power equipment.

[0069] Optionally, the opening and closing linkage mechanism 22 includes a linkage plate assembly 221, and the linkage plate assembly 221 includes a source plate 2211 and a moving plate component 2212; the moving plate component 2212 is on the movable housing 21, and the source plate 2211 acts on the moving plate component 2212 and has an opening position and a closing position; when the source plate 2211 is in the closing position, the moving plate component 2212 is located in the movement path of the grounding switch linkage 24 to limit the movement of the grounding switch linkage 24 on the housing 21; when the source plate 2211 in the closing position moves to the opening position, it acts on the moving plate component 2212, and the moving plate component 2212 disengages from the movement path of the grounding switch linkage 24.

[0070] For example, in this embodiment, the travel plate component 2212 is used as a barrier on the movement path of the grounding switch linkage 24, and the source plate 2211 is a power plate, which does not need to be in contact with the grounding switch linkage 24 to avoid damage.

[0071] For example, the longitudinal beam 31 of the pole assembly 30 is provided with a connecting rod 50, and the source plate 2211 is provided on the connecting rod 50. The above-mentioned power source is the pole assembly 30 in this embodiment. According to the prior art, it can be known that when the source plate 2211 is in the open position, the pole assembly rotates to a horizontal state and the pole assembly is powered off; when the source plate 2211 is in the closed position, the pole assembly rotates to a vertical state and the pole assembly is powered on.

[0072] Optionally, the moving plate component 2212 includes a moving plate 22121 and a first torsion spring 22122; the moving plate 22121 is rotatably set on the outer shell 21, the first torsion spring 22122 is set on the outer shell 21 and acts on the moving plate 22121, the moving plate 22121 includes an acting end 221211 and a limiting end 221212, the source plate 2211 acts on the acting end 221211 to drive the moving plate 22121 to rotate, and the limiting end 221212 is used to act on the grounding switch linkage 24.

[0073] In addition, the shifting member 23 includes a shifting plate 231 and a second torsion spring 232; the shifting plate 231 is rotatably set on the outer shell 21, and the second torsion spring 232 is set on the outer shell 21 and acts on the shifting plate 231. The shifting plate 231 includes a shifting end 2311 and an abutting end 2312. The shifting end 2311 is used to block the handle channel, and the abutting end 2312 is used to act on the grounding switch linkage 24.

[0074] For example, a vertical partition 2100 is provided in the cavity of the above-mentioned housing 21, and the shifting member 23 and the opening and closing linkage mechanism 22 are arranged on one side of the partition 2100, and the grounding switch linkage member 24 is movably arranged on the other side of the partition 2100. The moving plate 22121 and the shifting plate 231 are respectively connected to the side plates of the bracket by bolts. Preferably, one end of each bolt is connected to the middle of the moving plate 22121 and the shifting plate 231, respectively. The bolts are clamped on both sides of the side walls by at least two nuts to limit the bolts. The housing 21 is provided with a through hole 210 for inserting the operating handle, and the through hole 210 connects the operating channel with the outside.

[0075] In this embodiment, the shift plate 231 rotates in the horizontal direction, and a second through hole is provided on the partition 2100. The second torsion spring 232 is sleeved on the bolt of the shift plate 231. The second torsion springs 232 at both ends respectively abut against two opposite side surfaces of the shift plate 231, and the abutting end 2312 passes through the second through hole to reach the other side of the partition 2100.

[0076] In addition, a first through-hole is provided on the partition 2100, through which the limiting end 221212 of the positioning plate 22121 passes to reach the other side of the partition 2100. A first torsion spring 22122 is sleeved on the bolt connected to the positioning plate 22121. One end of the first torsion spring 22122 abuts against the side wall of the partition 2100, while the other end passes through the positioning plate 22121, with the upper end located between the limiting end 221212 and the bolt connected to the positioning plate 22121.

[0077] The linkage process of the restraining interlocking device formed above is: when the grounding switch is opened, the source plate 2211 is in the closed position as the initial state. At this time, the moving plate 22121 is in a horizontal state under the action of the first torsion spring 22122, the limiting end 221212 passes through the first through hole, and the top of the moving plate 22121 abuts against the top wall of the first through hole.

[0078] At this time, one end of the source plate 2211 is connected to the external starting source, and the other end is located below the action end 221211. The stopper 23 is in the blocking position, the stop end 2311 is located in the operating channel, and the abutting end 2312 passes through the second through hole to reach the other side of the partition 2100.

[0079] Optionally, the grounding switch linkage 24 includes an upper baffle 241 and a lower baffle 242; the upper baffle 241 and the lower baffle 242 are respectively on the movable housing 21, the lower baffle 242 is used to link to the external grounding switch to operate the grounding switch to close, and the upper baffle 241 is used as a movable path to enter the blocking member 23 to prevent the blocking member 23 from moving to the avoidance position.

[0080] In this embodiment, the upper baffle 241 and the lower baffle 242 can be independently provided on the housing 21 , and can be synchronously linked with each other through driving structures such as different motors controlled by a control circuit.

[0081] In other embodiments, the grounding switch linkage 24 may include an upper baffle 241, a lower baffle 242, and a connecting rod (not shown), wherein the upper baffle 241 and the lower baffle 242 are connected by a connecting rod. With the grounding switch in the open state as the initial state, the isolating switch is in the open state. The upper baffle 241 is below the abutment end 2312, and the top of the lower baffle 242 is below the limit end 221212 (a certain distance exists between the top of the lower baffle 242 and the bottom of the limit end 221212 so that the limit end 221212 can rotate downward and enter the first through hole). At this time, the operating handle is inserted into the through hole 210 and abuts against the shift end 2311. The shift plate 231 is positioned horizontally as a whole. The surface rotates clockwise (the second torsion spring 232 is compressed), so the gear end 2311 avoids (the gear member 23 is in the avoidance position), and the operating handle is inserted into the handle channel to perform the disconnect switch closing operation. The source moving plate 2211 reaches the closing position. At this time, the other end of the source moving plate 2211 is released from the contact with the moving plate 22121, and the limit end 221212 of the moving plate 22121 is blocked at the top of the lower baffle 242. The lower baffle 242 cannot move upward to close the grounding switch.

[0082] On the contrary, when the operating handle exits the operating channel, the second torsion spring 232 is released and rebounds to push the shift plate 231 to rotate back in the counterclockwise direction on the horizontal plane.

[0083] When the source plate 2211 reaches the open position, the other end of the source plate 2211 abuts against the action end 221211, and the travel plate 22121 rotates clockwise in the vertical plane, causing the limit end 221212 to rotate downward and enter the first through hole (the first torsion spring 22122 is compressed). At this time, the grounding switch linkage 24 is pushed upward to close the grounding switch, that is, the upper baffle 241 moves upward and blocks the second through hole, that is, the upper baffle 241 restricts the side of the abutting end 2312. At this time, the operating handle inserted into the through hole 210 will abut against the stop end 2311. The upper baffle 241 blocks the abutting end 2312, and the stop plate 231 cannot rotate. Therefore, the stop end 2311 cannot avoid, preventing the operating handle from being inserted, and the disconnector cannot be closed, thereby preventing misoperation.

[0084] In summary, the control interlocking device of this embodiment has the advantages of short transmission path, simple structure, strong controllability and high reliability.

[0085] In addition, combined with the above, it can be seen that after the isolating vacuum circuit breaker is pushed into the cabinet, the lower baffle 242 here protrudes from the bottom of the shell 21 and is linked with the grounding switch (including but not limited to automatic alignment and plugging of the plug rod and the socket, or manual locking, but it should be noted that manual locking requires manual unlocking).

[0086] Optionally, a plug-in protrusion 221210 is provided on the positioning plate 22121 ; when the limiting end 221212 is located in the movement path of the grounding switch linkage member 24 , the plug-in protrusion 221210 is plugged into the housing 21 .

[0087] Illustratively, the top wall of the first through hole of the partition 2100 is provided with a plug-in hole adapted to the plug-in protrusion 221210, and the plug-in protrusion 221210 is plugged into the plug-in hole to prevent the moving plate 22121 from shaking in the horizontal direction, thereby ensuring the reliability of the moving plate 22121 in limiting the grounding switch linkage 24.

[0088] Optionally, the shift plate 231 includes a first support rod 2301 and a second support rod 2302 connected to each other; the first support rod 2301 and the second support rod 2302 are arranged at an angle.

[0089] For example, the aforementioned shift end 2311 is one end of the first support rod 2301, and the abutting end 2312 is one end of the second support rod 2302. The shift plate 231 is configured as two support rods at an angle, which effectively reduces the overall length of the shift plate 231 and reduces the space occupied. In conjunction with the above, one end of the second torsion spring 232 acts on the inside of the second support rod 2302, and the other end acts on the outside of the first support rod 2301.

[0090] Optionally, the angle between the first support rod 2301 and the second support rod 2302 is between 110° and 150°.

[0091] Preferably, the angle between the first support rod 2301 and the second support rod 2302 is 120°. Other angles such as 110°, 115°, 125°, 135°, 140°, 145°, and 150° can be selected according to design requirements and will not be repeated here.
