Description

Technical Field

[0002] The upper end of the switch cabinet is a three-position switch, and the lower end is a vacuum circuit breaker. At present, the three-position switch generally adopts a spring-operated structure with two operating holes. One spring-operated structure passes through the operating hole to operate the disconnector. The other spring-operated structure operates the grounding switch through another operating hole. The two spring-operated structures are operated separately. The disconnector and the grounding switch cannot be closed at the same time. Therefore, the operating hole is usually locked by a fan-shaped plate and a limit rod to realize the mechanical interlocking function.

In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0050] In one embodiment, a switch cabinet includes a cabinet, an isolating switch, an earthing switch and an operating device. The isolating switch, the earthing switch and the operating device are arranged in the cabinet. The operating device is respectively connected to the isolating switch and the earthing switch for operating the closing or opening of the isolating switch and the earthing switch.

[0051] In one embodiment, if Figures 1 to 3 As shown, a switch operating device includes an operating member 100. The operating member 100 may be a handle. The operating member 100 is provided with a connecting portion 130 and a driving portion 110. Specifically, the end surface of the operating member 100 is provided with the connecting portion 130. The outer peripheral side of the operating member 100 is provided with the driving portion 110.

[0052] like Figure 4 and Figure 5As shown, a switch operating device includes a first transmission assembly 200. The first transmission assembly 200 is detachably connected to the connecting portion 130. The first transmission assembly 200 can be a transmission gear set. Specifically, the first transmission assembly 200 is composed of a plurality of meshing gears. The first transmission assembly 200 has a gear shaft. The gear shaft of the first transmission assembly 200 is detachably connected to the connecting portion 130. Specifically, the connecting portion 130 of the operating member 100 can be a groove structure. The gear shaft is inserted into the groove structure. More specifically, the gear shaft can be a hexagonal shaft. The cross-section of the groove structure is hexagonal.

[0053] In one embodiment, if Figure 4 and Figure 5 As shown, a switch operating device includes a first positioning assembly 300. The first positioning assembly 300 is used for transmission connection with an isolating switch and an earthing switch. By operating the first positioning assembly 300 to rotate, the isolating switch and the earthing switch are operated to close or open.

[0054] In one embodiment, the first positioning assembly 300 may be a positioning plate. The first positioning assembly 300 is connected to the first transmission assembly 200. The operating member 100 can drive the first transmission assembly 200 to rotate, so that the first transmission assembly 200 drives the first positioning assembly 300 to rotate.

[0055] In the traditional spring-operated mechanism of the switch cabinet, in order to make the switch contact withstand a large current, it is necessary to design a larger contact clamping force, thereby designing a larger spring force value. First, a larger spring force value is not convenient for manual operation of the switch. In addition, when opening the switch, a larger spring force value will cause the opening and closing impact force to be too large, causing the knife switch to shake too much.

[0056] In this embodiment, if Figure 5 As shown, the first transmission assembly 200 includes a first gear 210 and a second gear 220. The first gear 210 is meshed and connected with the second gear 220. The first gear 210 is connected to the connecting portion 130. The second gear 220 is connected to the first positioning assembly 300. The gear shaft of the second gear 220 is connected to the first positioning assembly 300. The size of the first gear 210 is smaller than the size of the second gear 220.

[0057] During operation, the connecting portion 130 of the operating member 100 is connected to the gear shaft of the first gear 210, and the operating member 100 is rotated, so that the operating member 100 drives the first gear 210 to rotate, the first gear 210 drives the second gear 220 to rotate, and the gear shaft of the second gear 220 drives the first positioning assembly 300 to rotate. That is, the small gear drives the large gear to rotate, which saves effort and facilitates the operation of closing or opening the disconnector and the grounding switch, avoiding the problem of excessive shaking of the knife switch.

[0058] Specifically, Figure 5As shown, the first transmission assembly 200 further includes a third gear 230. The third gear 230 is meshed with the first gear 210 and the second gear 220, respectively. That is, the first gear 210 is meshed with the second gear 220 through the third gear 230. The size of the third gear 230 is larger than the size of the first gear 210. The size of the third gear 230 is smaller than the size of the second gear 220.

[0059] In one embodiment, please refer to Figure 6 and Figure 7 A switch operating device includes a second positioning assembly 400. The second positioning assembly 400 includes a sliding member 410 and a locking member 420. The sliding member 410 can move in a direction close to or away from a groove 310 to be locked in or out of the groove 310. When the sliding member 410 is locked in the groove 310, the first positioning assembly 300 can be restricted from rotating. The locking member 420 can abut against the sliding member 410 to lock the sliding member 410 in the groove 310. Specifically, the locking member 420 can be a latch.

[0060] In one embodiment, the plurality of grooves 310 include a first groove 311, a second groove 312, and a third groove 313. The first groove 311 is located between the second groove 312 and the third groove 313. When the sliding member 410 is clamped in the first groove 311, the isolating switch and the earthing switch are in an open state. When the sliding member 410 is clamped in the second groove 312, the earthing switch is in a closed state. When the sliding member 410 is clamped in the third groove 313, the isolating switch is in a closed state.

[0061] In one embodiment, if Figure 7 As shown in FIG. 1 , the second positioning assembly 400 includes a supporting body 430 and a limiting member 440. The locking member 420 is rotatably disposed on the supporting body 430. The limiting member 440 is disposed on the supporting body 430 and can abut against one side of the locking member 420 to limit the locking member 420 from rotating in the first direction. Figure 8 and Fig. 9 As shown, the first direction may be a clockwise direction.

[0062] In one embodiment, the second positioning assembly 400 includes a second torsion spring 450. One end of the second torsion spring 450 is connected to the support body 430, and the other end is connected to the first side of the locking member 420. The second torsion spring 450 is used to provide an elastic force for the locking member 420 to rotate along the first direction.

[0063] It should be noted that when the second rotating assembly is not rotating, the locking member 420 is in a self-locking state under the action of the limit member 440 and the second torsion spring 450. That is, the locking member 420 abuts against the sliding member 410, and the sliding member 410 is stuck in the groove 310 to limit the rotation of the first positioning assembly 300. The second rotating assembly drives the locking member 420 to rotate along the second direction so that the locking member 420 unlocks the sliding member 410. The second direction is opposite to the first direction. Specifically, as shown in the attached Figure 8 and Fig. 9 As shown, the second direction may be counterclockwise.

[0064] In one embodiment, the second positioning assembly 400 further includes a positioning bracket 460. The positioning bracket 460 is disposed on the supporting body 430. Fig. 9 As shown, a sliding groove 461 is provided on the positioning bracket 460. The sliding groove 461 can be arranged along the vertical direction. The sliding member 410 is slidably arranged in the sliding groove 461.

[0065] In one embodiment, if Figure 6 and Figure 7 As shown, the second positioning assembly 400 includes a second elastic member 470. The second elastic member 470 can be a spring. One end of the second elastic member 470 is connected to the sliding member 410, and the other end is connected to the supporting body 430. The second elastic member 470 is used to provide an elastic force to the sliding member 410 close to the groove 310.

[0066] In one embodiment, if Figure 6 and Figure 7 As shown, a rolling wheel 411 is provided at one end of the sliding member 410 facing the groove 310. The rolling wheel 411 can be clamped in the groove 310 to facilitate the sliding member 410 to switch between different grooves 310.

[0067] In one embodiment, if Figure 4 As shown, a switch operating device includes a second transmission assembly 500. The second transmission assembly 500 abuts against the driving part 110. The second transmission assembly 500 is connected to the locking member 420. The driving part 110 drives the second transmission assembly 500 to move, so that the second transmission assembly 500 drives the locking member 420 to move, and then the locking member 420 can lock or unlock the sliding member 410.

[0068] In one embodiment, if Figure 5 As shown, the second transmission assembly 500 includes a first transmission member 510, a second transmission member 520 and a rotating rod 530. The first transmission member 510 is in contact with the driving portion 110. One end of the second transmission member 520 is connected to the first transmission member 510, and the other end is connected to one end of the rotating rod 530. The other end of the rotating rod 530 is connected to the locking member 420.

[0069] During operation, the driving unit 110 drives the first transmission member 510 to move toward the direction close to the rotating rod 530 , so that the second transmission member 520 drives the rotating rod 530 to rotate, and the rotating rod 530 drives the locking member 420 to rotate.

[0070] In one embodiment, if Figure 5 As shown, the first transmission member 510 includes a pinch plate 511, a first torsion spring 512 and a rotating plate 513. The pinch plate 511 can abut against the driving part 110. One end of the first torsion spring 512 is connected to the pinch plate 511, and the other end is connected to one end of the rotating plate 513. The other end of the rotating plate 513 is used for rotational connection with the frame of the operating device. After the operating member 100 is separated from the connecting part 130, the first torsion spring 512 can reset the pinch plate 511, so that the operating member 100 can operate the pinch plate 511 again next time.

[0071] In one embodiment, the buckle plate 511 is an arc-shaped plate. The operating member 100 is a cylindrical handle. The driving unit 110 rotates along the arc-shaped side of the arc-shaped plate. When the driving unit 110 rotates along the side of the arc-shaped plate to a preset position, the driving unit 110 is separated from the arc-shaped plate. Fig.10 The state where the driving part 110 is in contact with the buckle plate. Fig.11 and Fig.12 As shown, the driving part 110 is in a state of being separated from the buckle plate 511. Specifically, the driving part 110 can be a first protrusion provided at one end of the cylindrical handle close to the arc plate.

[0072] In one embodiment, if Figure 5 As shown, the second transmission assembly 500 may further include a first elastic member 540. One end of the first elastic member 540 is connected to one end of the second transmission member 520 away from the rotating rod 530. The first elastic member 540 is used to provide an elastic force to the second transmission member 520 away from the rotating rod 530. When the driving part 110 of the operating member 100 stops driving the first transmission member 510, the elastic member drives the second transmission member 520 to reset, so that the locking member 420 is in a waiting reset state, and the operating member 100 continues to rotate to the preset position, and the locking member 420 resets and locks the sliding member 410. For example, the operating member 100 rotates to the preset position may be a position after the operating member 100 rotates two circles.

[0073] In one embodiment, if Figures 1 to 3 As shown, the operating member 100 is further provided with a second protrusion 120. The second protrusion 120 is arranged opposite to the driving portion 110. That is, the second protrusion 120 is arranged opposite to the first protrusion.

[0074] like Figure 4 and Figure 5As shown, the operating device also includes a first operating plate 610 and a second operating plate 620 arranged opposite to each other. The first operating plate 610 and the second operating plate 620 form an operating space. The first transmission assembly 200 is arranged through the first operating plate 610. The second operating plate 620 is provided with a first through hole 621. The hole wall of the first through hole 621 is provided with a second through hole 622 adapted to the second protrusion 120. The operating member 100 is arranged through the first through hole 621 and the second through hole 622 and connected to the first transmission assembly 200.

[0075] The second protrusion 120 is located in the operating space, and the second transmission assembly 500 drives the locking member 420 to unlock the sliding member 410 .

[0076] It is understandable that the second protrusion 120 serves as an identification. When the second protrusion 120 passes through the second through hole 622 , the locking member 420 unlocks the sliding member 410 .

[0077] When the disconnector or earthing switch needs to be closed or opened, the operating member 100 is detachably connected to the first transmission assembly 200. The operating member 100 drives the first transmission assembly 200 to rotate. The driving portion 110 abuts against the second transmission assembly 500. The driving portion 110 drives the second transmission assembly 500 to move, so that the second transmission assembly 500 drives the locking member 420 to move, and then the locking member 420 can unlock the sliding member 410, and the sliding member 410 can move in a direction away from the groove 310. The first transmission assembly 200 drives the first positioning assembly 300 to rotate. The sliding member 410 moves in a direction away from the groove 310. When the first positioning assembly 300 switches to another groove 310, the sliding member 410 is stuck in the other groove 310. The driving portion 110 of the operating member 100 stops driving the second transmission assembly 500, and the locking member 420 is in a reset state. The operating member 100 continues to rotate to the preset position, and the locking member 420 resets and locks the sliding member 410. The locking member 420 locks the sliding member 410 in another groove 310. By rotating the first transmission assembly 200 in different directions to determine the switching position of the groove 310, the disconnector and the earthing switch are operated to close or open. For example, when the sliding member 410 is stuck in the first groove 311, the disconnector and the earthing switch are in the open state. When the first transmission assembly 200 rotates in the clockwise direction and switches to the position of the second groove 312, the sliding member 410 is stuck in the second groove 312, and the earthing switch is in the closed state. When the first transmission assembly 200 rotates in the counterclockwise direction and switches to the position of the third groove 313, the sliding member 410 is stuck in the third groove 313, and the disconnector is in the closed state. Therefore, the operating device does not have the problem of closing the disconnector and the earthing switch at the same time, and there is no need to set up an additional mechanical interlocking mechanism, which can reduce the volume of the switch cabinet and reduce the cost of the switch cabinet.

[0078] Working principle:

[0079] When the disconnector or earthing switch needs to be closed or opened, the first protrusion of the operating member 100 is aligned with the second through hole 622 of the second operating plate 620, so that the operating member 100 partially extends into the operating space. The first protrusion of the operating member 100 abuts against the buckle plate 511, and the connecting portion 130 of the operating member 100 is connected to the gear shaft of the first gear 210. The operating member 100 pushes the buckle plate 511 to move toward the direction close to the rotating rod 530. The buckle plate 511 drives the rotating plate 513 to move toward the direction close to the rotating rod 530. The rotating plate 513 drives the second transmission member 520 to move. The second transmission member 520 drives the rotating rod 530 to rotate. At this time, the first elastic member 540 is in a compressed state. After the second protrusion 120 of the operating member 100 passes through the second through hole 622 of the second operating plate 620, the operating member 100 reaches the preset depth of the operating space. The upper end of the rotating rod 530 drives the locking member 420 to rotate in the counterclockwise direction. The locking member 420 unlocks the sliding member 410 .

[0080] The operating member 100 is rotated, and the operating member 100 drives the first gear 210 to rotate, and the first gear 210 drives the third gear 230 to rotate, and the third gear 230 drives the second gear 220 to rotate, so that the first positioning assembly 300 on the positioning shaft of the second gear 220 rotates, and then the sliding member 410 slides upward. When the operating member 100 rotates to a certain angle, the first protrusion is separated from the pinch plate 511, and the pinch plate 511 is in a disengaged state. The first protrusion of the operating member 100 no longer presses against the pinch plate 511, and the force driving the pinch plate 511 and the rotating plate 513 to move toward the rotating rod 530 is removed. The first elastic member 540 drives the second transmission member 520 away from the rotating rod 530, and the rotating rod 530 rotates in the opposite direction. The rotating rod 530 no longer drives the locking member 420. The locking member 420 is in a waiting state to be reset. After the operating member 100 continues to rotate to the preset position, the locking member 420 is reset under the elastic force of the second torsion spring 450. When the operating member 100 rotates two circles, the rolling wheel 411 of the sliding member 410 is locked in another groove 310 under the elastic force of the second elastic member 470. The locking member 420 is reset and abuts against the sliding member 410, limiting the rotation of the first positioning assembly 300, so that the entire operating device is in a locked state.
