Description

Technical Field

[0001] The present invention relates to the field of circuit breaker operating mechanisms, and in particular to an opening and closing operation module and a spring operating mechanism. Background Art

[0002] High-voltage circuit breakers are crucial electrical components in power systems, connecting and disconnecting circuits during normal operation and rapidly disconnecting faulty circuits through relay protection in the event of a fault. Vacuum circuit breakers used in switchgear currently on the market are generally driven by a spring-operated mechanism, whose opening and closing mechanisms are the core components for circuit breaker control.

[0003] A typical spring-operated mechanism in the prior art includes a main body, which is equipped with a mechanism output shaft for outputting operating power, an energy storage shaft equipped with a cam, a closing half-shaft for achieving closing control, and an opening half-shaft for achieving opening control. For example, patent document CN111681908A discloses a circuit breaker spring-operated mechanism in which the closing half-shaft is equipped with a closing trip plate. The closing trip plate is used to be pushed by a closing electromagnet or a manual closing push rod to drive the closing half-shaft to rotate, achieving the closing operation. During closing, the closing trip plate, driven by the closing electromagnet or manual closing push rod, drives the closing half-shaft to rotate, thereby triggering the energy storage holding latch to rotate and achieve closing. During opening, the opening trip plate, driven by the opening electromagnet or manual opening push rod, drives the opening half-shaft to rotate, releasing the opening latch, and driving the closing holding latch at the bottom of the opening latch to rotate, achieving opening. An auxiliary switch is often provided on the existing spring operating mechanism, and a transmission mechanism is provided between the auxiliary switch and the output shaft of the mechanism for detecting the state of the spring operating mechanism.

[0004] However, the closing of the spring operating mechanism requires a corresponding set of electromagnets and manual drive structures, and the opening of the switch also requires a corresponding set of electromagnets and manual drive structures. There are many parts for manual and electric closing and opening, and they are assembled in different positions of the spring operating mechanism in a scattered manner. The structure is complex, and the accurate position of the manual and electric closing and opening parts needs to be ensured. The assembly process is demanding, and the installation and maintenance are difficult and the operation is inconvenient. Summary of the Invention

[0005] The object of the present invention is to provide a switch opening and closing operation module to solve the problem that the existing spring operating mechanism for manual and electric switch opening and closing has many and dispersed parts, which makes installation and maintenance difficult and inconvenient. Another object of the present invention is to provide a spring operating mechanism to solve the problem that the existing spring operating mechanism for manual and electric switch opening and closing has many and dispersed parts, which makes installation and maintenance difficult and inconvenient.

[0006] The present invention adopts the following technical solutions:

[0007] The opening and closing operation module is used to be installed in a spring operating mechanism with an opening half-axis and a closing half-axis, and includes a module body, an opening shaft, a manual opening push piece, a manual closing push piece and a closing pressure plate; the opening shaft is rotatably assembled on the module body, the manual opening push piece and the manual closing push piece are guide-assembled on the module body, a manual opening conversion structure is provided between the manual opening push piece and the opening shaft, and a manual closing conversion structure is provided between the manual closing push piece and the closing pressure plate; one end of the closing pressure plate is a hinged end, which is hinged to a hinged seat provided on the opening and closing operation module, and the other end is a closing trigger end, which is used to overlap the closing trip plate provided on the closing half-axis, so as to swing when the closing pressure plate is pressed by the closing electromagnet on the spring operating mechanism At the same time, the closing trip plate is driven to swing to achieve closing; the opening shaft has an opening position and a reset position in its rotation stroke; the opening shaft is provided with an opening crank arm and an electric opening pressure plate, and the opening crank arm is used to be connected to the opening trip plate arranged on the opening half shaft through the opening connecting rod, and drives the opening trip plate to swing when the opening shaft swings to the opening position to achieve opening; the electric opening pressure plate is used to drive the opening shaft to swing to the opening position under the top pressure of the opening electromagnet on the spring operating mechanism; the manual opening conversion structure is used to convert the linear motion of the manual opening push piece into the rotation of the opening shaft to achieve manual opening, and the manual closing conversion structure is used to convert the linear motion of the manual closing push piece into the swing of the closing pressure plate pressing against the closing trip plate to achieve manual closing.

[0008] Beneficial effects: The opening arm provided on the opening shaft can be connected to the opening connecting rod, so as to realize the linkage between the opening mechanism on the mechanism body and the opening and closing module, so that the electric opening pressure plate can be adapted to the opening electromagnet to realize electric closing, and the opening shaft can be adapted to the manual opening push piece through the manual opening conversion structure to realize manual closing; in addition, the closing trigger end of the closing pressure plate can be overlapped on the closing trip plate provided on the closing half-shaft, so as to realize the linkage between the closing mechanism on the mechanism body and the opening and closing module, and the closing pressure plate can drive the closing trip plate when it swings under the pressure of the closing electromagnet. The manual closing push piece and the closing pressure plate can be coordinated with the manual closing conversion structure to realize manual driving of the closing pressure plate to realize the closing function; on the whole, the module body integrates the opening shaft, the manual opening push piece, the closing pressure plate and the manual closing push piece, realizing the integration of electric opening and closing and manual opening and closing functions. Compared with the dispersed arrangement of manual and electric opening and closing structures in the prior art, the structure is compact, which is conducive to ensuring the accurate installation of various components, reducing the assembly process requirements and the difficulty of installation and maintenance, and can facilitate operators to carry out installation and maintenance operations.

[0009] Furthermore: a driving ear plate is protruding on the opening shaft, and the hinged end of the closing pressure plate is hinged on the driving ear plate. In the pressure direction of the closing trigger end, the hinge point is opposite to the opening shaft and is located on the side of the opening shaft corresponding to the pressure direction; when the opening shaft swings to the opening position, the closing pressure plate moves away under the drive ear plate to avoid being triggered by the closing electromagnet or the closing drive lever.

[0010] The beneficial effect of the above further improvement is that, through the above transmission structure between the opening shaft and the closing pressure plate, when the opening shaft swings to the opening position, the closing pressure plate can be moved away to prevent the closing pressure plate from being triggered by the closing electromagnet or the closing drive lever, thereby realizing the anti-jump function, that is, avoiding the problem of cyclic closing and opening when closing and opening are triggered at the same time, which can prevent misoperation and help improve reliability.

[0015] Furthermore: the pusher claws are arranged at two locations along the axial direction of the release adapter shaft, and the two pusher claws form two limit cantilevers on the release adapter shaft. The closing pressure plate is clamped between the two pusher claws and cooperates with the pusher claws along the axial limit of the release adapter shaft.

[0077] like Figure 4 、 Figure 5 The opening and closing operation module includes a module body 21, which is a frame structure and is provided with an opening control unit, a closing control unit and a linkage unit.

[0078] The module body 21 is detachably fixed to the mechanism body 11 by the module connecting bolts 23. Figure 3 、 Figure 5 and Figure 6 The bottom of the frame structure is provided with a downwardly protruding connecting lug 22, which is provided with bolt holes, allowing for detachable fixing via module connecting bolts 23. In addition to the surrounding frame, the module body 21 is provided with a cross-shaped cross rib in the middle, including front and rear extension ribs 24 and left and right extension ribs 25.

[0079] like Figure 4 、 Figure 5 and Figure 7 The opening control unit includes an opening shaft 31 rotatably mounted on the module body 21. The structure of the opening shaft 31 is as follows: Figure 8 As shown, the main body has a cross-shaped cross section, and the cross-shaped cross section is used to ensure structural strength. Figure 4 The trip shaft 31 is connected to a trip reset spring 32 for applying a driving force to the trip shaft 31 toward the reset position. The trip reset spring 32 is formed by a torsion spring sleeved on the front and rear ends of the trip shaft 31. The trip shaft 31 has a trip position and a reset position when working. The trip position is Figure 4 and Figure 5The position shown is the corresponding position when it is rotated left to the set angle, and the reset position is Figure 4 and Figure 5 As shown in the position. Figure 8 , a tripping arm 33 is convexly provided on the outer circumferential surface of the tripping shaft 31, and a driving ear plate 35 and a pushed cantilever 37 are provided in front of the tripping arm 33 in sequence. A hinge hole is provided on the tripping arm 33, and the hinge hole is used to connect with the tripping trip plate 15 provided on the tripping half-shaft 14 through the tripping connecting rod 91 to form a connecting rod mechanism, so as to drive the tripping trip plate 15 to swing when the tripping shaft 31 swings to the tripping position, thereby realizing the tripping of the spring operating mechanism. The front end of the tripping shaft 31 is rotatably assembled in the circular hole on the front side wall of the module body 21, and the rear end is rotatably assembled in the U-shaped slot at the top of the rear side wall of the module body 21. The U-shaped slot includes a circular part at the bottom and a straight slot part connected to the upper part of the circular part, and the slot width of the straight slot part is smaller than the diameter of the circular part. The rear end of the trip shaft 31 is provided with a tangent plane on one radial side. During installation, the tangent plane of the trip shaft 31 is made parallel to the groove wall of the straight groove portion on the U-shaped slot. Then, the trip shaft 31 is pressed downward to expand the U-shaped slot to a certain extent, so that the trip shaft 31 is installed in the circular portion. At this time, the U-shaped slot can limit the trip shaft 31 and realize the normal rotation of the trip shaft 31. This installation structure can facilitate the installation of the trip shaft 31. In other embodiments, a limiting pressure plate can also be fixed at the opening of the U-shaped slot. The limiting pressure plate spans both sides of the slot width direction of the U-shaped slot and can be fixed to the module body by screws to prevent the trip shaft 31 from falling out of the U-shaped slot.

[0080] The driving ear plate 35 is used to match the closing pressure plate 51 in the closing control unit, and the specific structure will be described in detail below. The pushed cantilever 37 is arranged below the opening shaft 31, and the cross section is U-shaped. The arc surface portion of the pushed cantilever 37 corresponding to the bottom of the U shape is used to match the manual opening push piece 41 guided and assembled on the module body 21 to achieve manual opening. The "guided assembly" in the present invention is to assemble two objects together in the form of a guided fit, which can achieve relative translation of the two objects along a set direction. For example, if a rod is inserted into a sleeve in the form of a sliding fit, it can be considered that the rod is guided and assembled on the sleeve. For another example, the tailstock on a lathe slides along the lathe guide rail, and the tailstock is considered to be guided and assembled on the lathe guide rail.

[0081] like Figure 4 、 Figure 7 、 Figure 9The manual opening push piece 41 is a plate-like structure with a circular button at the front end, which is basically the same as the structure of the manual closing push piece 61 described below. The manual opening push piece 41 is guided and assembled in the guide slots provided on the surrounding frame of the module body 21 and the left and right extended ribs 25. The shape of the guide slots matches the outer contour of the manual opening push piece 41. In order to better achieve the reliable operation of the manual opening push piece 41, a push piece reset spring 42 is provided between the manual opening push piece 41 and the manual closing push piece 61 and the left and right extended ribs 25. The push piece reset spring 42 is sleeved on the spring mounting column provided in the middle of the width direction of the manual opening push piece 41 and the manual closing push piece 61. Of course, an anti-slip structure should also be provided between the manual opening push piece 41 and the module body 21 to prevent the push piece reset spring 42 from causing the manual opening push piece 41 to slip off the module body 21. This can be designed by those skilled in the art without any creative work. In this embodiment, the anti-slip structure includes an elastic cantilever 43 provided on the right side of the manual trip pusher 41. The rear end of the elastic cantilever 43 is provided with a stopper protrusion for engaging with the notch edge of the guide slot on the module body 21. The rear end edge of the plate-like structure is an inclined edge, forming a trip pusher inclined surface 44 at the rear end of the manual trip pusher 41. The cooperation between the pushed cantilever 37 and the trip pusher inclined surface 44 forms a manual trip conversion structure, which can convert the linear motion of the manual trip pusher 41 into the rotation of the trip shaft 31 toward the trip position.

[0082] like Figure 7 、 Figure 8 An electric trip pressure plate 38 is fixed to the trip shaft 31 on the side facing away from the pushed cantilever 37. The electric trip pressure plate 38 is pressed against the trip electromagnet 112 fixed to the mechanism body 11, thereby driving the trip shaft 31 to swing toward the trip position. In this embodiment, a vertically arranged electromagnet mounting plate 111 is provided at the top of the mechanism body 11, above the tripping and closing operating modules. The trip electromagnet 112 is mounted to the right of the electromagnet mounting plate 111.

[0083] The closing control unit includes a closing pressure plate 51 , a manual closing push piece 61 and a closing drive lever 63 .

[0084] like Figure 5 、 Figure 10The closing pressure plate 51 extends horizontally, with its right end being the hinged end and its left end being the closing trigger end. A slot 52 is provided at the hinged end of the right end of the closing pressure plate 51. The slot 52 extends horizontally, through which the corresponding hinge shaft passes. The closing pressure plate 51 is hinged to the drive lug 35 on the opening shaft 31 via a circular hole that matches the hinge shaft. A circular spring mounting cavity is provided in the closing pressure plate 51, and a reset spring is provided in the spring mounting cavity as the pressure plate reset spring 53. The left end of the pressure plate reset spring 53 is supported on the closing pressure plate 51, and the right end is used to press against the side end surface of the driving ear plate 35 to apply a force to the closing pressure plate 51 away from the opening shaft 31; a spring support pad 54 is also installed in the spring mounting cavity. The right end of the pressure plate reset spring 53 is supported on the spring support pad 54. By pressing the spring support pad 54 on the driving ear plate 35, the closing pressure plate 51 can be reset to the left. Figure 2 The bottom of the hinged end of the closing pressure plate 51 is connected to the closing trip plate 17 provided on the closing half shaft 16 of the spring operating mechanism, and is used to drive the closing trip plate 17 to swing when under pressure, triggering the closing of the spring operating mechanism. The closing trip plate 17 is connected to a reset spring, which can provide elastic reset force and realize the upward reset of the closing pressure plate 51. Figure 4 、 Figure 5 、 Figure 7 and 10 The top of the hinged end is provided with an electric closing pushing boss 55 for the closing electromagnet 113 installed on the electromagnet mounting plate 111 to push. When the closing electromagnet 113 is energized, it can act on the electric closing pushing boss 55 to push the closing pressure plate 51 downward.

[0085] like Figure 4 、 Figure 7 、 Figure 9 The main structure of the manual closing push piece 61 is the same as that of the manual closing push piece 61, both of which are horizontally arranged plate-shaped structures. However, an inclined push plate 62 is provided on the top of the manual closing push piece 61. The inclined push plate 62 has an inclined surface inclined upward to form a closing push inclined surface. Figure 6The inner side of the left side wall of the module body 21 is provided with a lever shaft 26 extending horizontally, for articulating a closing drive lever 63. The swing axis of the closing drive lever 63 is perpendicular to the guide direction of the manual closing push member 61. The front end of the closing drive lever 63 is provided with a cylinder extending horizontally, which is used to adapt to the closing push inclined surface to convert the linear motion of the manual closing push member 61 into rotation of the closing drive lever 63, thereby driving the closing drive lever 63, which is hinged to the inner side of the left side wall of the module body 21, to swing. The rear end of the closing drive lever 63 is also provided with a cylinder extending horizontally, which is used to adapt to the closing trigger end of the closing pressure plate 51 to drive the closing pressure plate 51 to swing in the direction of pressing down on the closing trip plate 17, thereby triggering the closing trip plate 17 and closing the spring-operated mechanism. The closing push inclined surface of the manual closing push member and the closing drive lever form a manual closing conversion structure. In other embodiments, the manual opening conversion structure and the manual closing conversion structure can also be replaced with other forms. For example, the manual opening conversion structure adopts a lever-driven form similar to the manual closing conversion structure, while the manual closing conversion structure adopts a direct driving form relying on an inclined plane similar to the manual opening conversion structure.

[0086] The opening and closing operation module is also rotatably equipped with a release adapter shaft 71. The structure of the release adapter shaft 71 is as follows: Figure 11 , its cross-section is also cross-shaped and arranged parallel to the tripping shaft 31. A tripping pressure plate 72 is fixed to its top. The tripping electromagnet (not shown in the figure, fixed to the electromagnet mounting plate 111, located in front of the closing electromagnet 113) pushes downward on the tripping pressure plate 72 to rotate the tripping adapter shaft. Two pusher claws 73 are also protruding from the tripping adapter shaft. The closing pressure plate 51 is also provided with protruding posts 56 on the front and rear sides, respectively, that adapt to the pusher claws 73. The protruding posts 56 constitute an adaptive stop structure, which is used to drive the closing pressure plate 51 to translate toward the tripping shaft 31 when the tripping adapter shaft 71 rotates in the corresponding direction, thereby pushing the tripping shaft 31 toward the open position via the reset compression spring. It should be noted that since some current circuit breakers are equipped with integrated protectors that can send a tripping signal through the integrated protector when a tripping is detected, the aforementioned tripping adapter shaft 71 is a reserved function and can be omitted in other embodiments. The two pusher claws 73 form two limit cantilevers on the release adapter shaft 71. The limit cantilevers extend downward and are arranged at intervals along the axial direction of the release adapter shaft 71. The closing pressure plate 51 is clamped between the two pusher claws 73 and cooperates with the pusher claws 73 to limit the axial direction of the release adapter shaft 71.

[0087] like Figure 4 、 Figure 12The linkage unit includes a linkage shaft 81 that is rotatably mounted on the opening and closing operation module. The linkage shaft 81 is located between the opening shaft 31 and the trip unit adapter shaft 71 and is rotatably mounted on the module body 21 through six U-shaped shaft support grooves 27 provided on the module body 21. The top and bottom of the front and rear extension ribs 24 of the module body 21 are provided with threaded holes, and are fixedly connected with a positioning plate 83 by screws. The structure of the positioning plate 83 is as follows: Figure 13 As shown, the positioning plate 83 includes a main body 84 with fixing ears corresponding to the top threaded holes of the front and rear extension ribs 24, and a downwardly extending fixing arm 87. The bottom of the fixing arm 87 is provided with fixing ears corresponding to the bottom threaded holes of the front and rear extension ribs 24. After being fixed to the module body 21, the positioning plate 83 can retain the linkage shaft 81 in the shaft support groove 27 along the notch of the shaft support groove 27. It can also adapt to the impact strength of the linkage shaft 81 when the mechanism output shaft 19 moves, ensuring the reliability of the connection.

[0088] like Figure 12 The linkage shaft 81 is provided with a first linkage swing arm 85 and a second linkage swing arm 86. The first linkage swing arm 85 is hinged to one end of the corresponding auxiliary switch connecting rod 92. Figure 1 The other end of the auxiliary switch link 92 is hinged to the auxiliary switch 110 input shaft crank arm on the spring operating mechanism, which can drive the auxiliary switch 110 through the auxiliary switch link 92. The second linkage swing arm 86 is hinged to one end of the corresponding linkage link 93. The other end of the linkage link 93 is hinged to the transmission plate 115 fixed to the mechanism output shaft 19 of the spring operating mechanism. Driven by the mechanism output shaft 19 and the linkage link 93, the linkage shaft 81 can be driven to swing, thereby realizing the operation of the auxiliary switch 110.

[0089] The module body 21, opening shaft 31, trip adapter shaft 71, closing pressure plate 51, linkage shaft 81, manual opening push piece 41, and manual closing push piece 61 are respectively integrally cast from high-strength plastic, which is easy to manufacture and low in cost.

[0090] The opening and closing process of the above spring operating mechanism:

[0091] When closing the circuit breaker, the left end of the closing pressure plate 51 needs to move downward, that is, swing counterclockwise, thereby pushing the closing trip plate 17.

[0092] Specifically, during electric closing, the closing electromagnet 113 activates once, pushing the closing trigger on the left end of the closing pressure plate 51 downward. This trigger drives the closing trip plate 17 downward. At this point, the closing half-shaft 16 rotates, causing the energy storage retaining plate, which fits into the groove at the front end of the closing half-shaft 16, to release. The energy storage spring releases energy, and the spring operating mechanism closes the circuit breaker. After closing is complete, the closing trip plate 17 resets due to the action of its connected reset spring, and the closing pressure plate 51 also resets, preparing for the next closing.

[0093] To manually close the circuit breaker, push the manual closing pusher 61. The inclined push plate 62 on the manual closing pusher 61 rotates the closing drive lever 63, which in turn pushes the closing pressure plate 51 downward. The subsequent operation is the same as for electric closing. After manual closing is completed, the manual closing pusher 61 is reset by the corresponding pusher return spring.

[0094] When opening the switch, the opening shaft 31 needs to swing counterclockwise, and the opening trip plate 15 provided on the opening half-shaft 14 is driven to swing through the opening connecting rod 91.

[0095] Specifically, during electric tripping, the tripping electromagnet 112 activates once, pressing the electric tripping pressure plate 38 to drive the tripping shaft 31 to rotate counterclockwise. Simultaneously, the tripping arm 33 on the tripping shaft 31 moves upward, pulling the tripping trip plate 15 via the tripping connecting rod 91, causing the tripping half-shaft 14 to rotate, thereby releasing the closing holding latch 18 and opening the mechanism. Under the action of the tripping reset spring 32 connected to the tripping shaft 31, the tripping shaft 31 resets, preparing for the next trip.

[0096] To manually open the circuit breaker, push the manual opening push piece 41. The opening push inclined surface 44 at the rear end of the manual opening push piece 41 drives the opening shaft 31 to rotate via the pushed cantilever 37. The subsequent operation is the same as for electric opening. After the manual opening is completed, the manual opening push piece 41 is reset by the corresponding push piece reset spring 42.

[0097] During the opening and closing process, the mechanism output shaft 19 rotates and drives the transmission plate 115 to rotate, which drives the linkage shaft 81 to rotate through the linkage connecting rod 93, so that the first linkage swing arm 85 on the linkage shaft 81 pulls the auxiliary switch 110 through the auxiliary switch connecting rod 92 to switch the state of the opening and closing auxiliary contacts.

[0098] If the opening and closing operation module needs to be replaced, the module connecting bolts 23 and the three connecting rods of the opening connecting rod 91, the linkage connecting rod 93 and the auxiliary switch connecting rod 92 can be removed for replacement, which is convenient and quick.

[0099] Embodiment 2 of the spring operating mechanism of the present invention:

[0100] This embodiment differs from Example 1 in that, in Example 1, the closing pressure plate 51 is hinged to the driving lug 35 on the opening shaft 31, forming a hinged seat that provides an anti-jump function. In this embodiment, however, the closing pressure plate 51 is hinged to the mold body 21, forming a hinged seat that eliminates the anti-jump function.

[0101] Embodiment 3 of the spring operating mechanism of the present invention:

[0102] This embodiment differs from Embodiment 1 in that, in Embodiment 1, the hinged end of the closing pressure plate 51 is provided with a slotted hole, and a pressure plate return spring 53 is provided on the closing pressure plate 51. In this embodiment, the hinged hole on the hinged end of the closing pressure plate 51 is a round hole. When the closing pressure plate 51 translates to the right, the force is directly transmitted to the opening shaft through the hinged hole, and the pressure plate return spring 53 is no longer provided.

[0103] In the above embodiment, the module body 21 is provided with a linkage shaft 81 and a release adapter shaft 71. In other embodiments, the linkage shaft 81 or the release adapter shaft 71 may be omitted according to usage requirements.

[0104] The embodiment of the opening and closing operation module in the present invention is the opening and closing operation module described in any embodiment of the above-mentioned spring operating mechanism, which will not be described in detail in the present invention.

[0105] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall be included in the scope of protection of the present invention.
