Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment, and in particular to a disconnector opening and closing detection device. Background Art

[0002] Combined electrical appliances are electrical components that encapsulate switchgear other than transformers in a grounded metal casing and fill it with SF6 gas at a certain pressure as an insulating medium. Combined electrical appliances are widely used in power grids for their compact structure, small appearance and installation size, easy use, and little impact from the external environment. At present, due to the metal-enclosed characteristics of combined electrical appliances, whether the internal isolating switch knife gate is open or closed is mainly judged by external indicators.

[0003] According to the statistics of power grid operation data, this method of detecting the opening and closing positions of disconnecting switches is prone to the situation that when all external indicators of the disconnecting switch indicate that the disconnecting switch is in place, the internal moving and static contacts are not actually in place. The detection accuracy of the opening and closing positions is low, which can easily cause serious accidents and greatly endanger the safety of the power grid and operators.

[0004] In the prior art, the operation conditions inside the combination electrical box and the operating cavity are observed through a camera, thereby realizing the detection of the open and closed positions of the isolating switch inside the combination electrical box. However, when using image detection, it is difficult to perform quantitative analysis and judgment on the detection results of the open and closed states of the combination electrical isolating switch, which makes the judgment of the detection results prone to errors.

[0038] Embodiment 1

[0039] like Figure 1-Figure 4 As shown, this embodiment provides an isolating switch opening and closing detection device, which is used to detect the opening and closing of the isolating switch and take action according to the detection result to keep the isolating switch in a connected state.

[0040] The isolating switch opening and closing detection device includes a base 1, a light detection mechanism 2 and a plug-in detection mechanism. The light detection mechanism 2 is arranged on the base 1. The light detection mechanism 2 includes a light emitter 21 and a light receiver 22 arranged relatively to each other, and an isolating switch is arranged between the light emitter 21 and the light receiver 22; the plug-in detection mechanism is arranged on the base 1, and the plug-in detection mechanism is electrically connected to the light detection mechanism 2. The plug-in detection mechanism includes a driving component 31 and a plug-in component 32 and a clamping component 35 that are transmission-connected to the driving component 31. The plug-in detection mechanism is configured so that when the light receiver 22 receives light, the driving component 31 drives the plug-in component 32 to be inserted into the gap of the isolating switch to connect the isolating switch, and after the plug-in component 32 is inserted into the gap, the driving component 31 can drive the clamping component 35 to clamp the plug-in component 32.

[0041] The isolating switch opening and closing detection device provided by the present invention is arranged between the isolating switch and the light receiver. When the isolating switch is loose or disconnected, the light receiver 22 can receive the light emitted by the light transmitter 21. After the light receiver 22 receives the light, the driving component 31 of the plug detection mechanism drives the plug component 32 to be inserted into the gap of the isolating switch, so that the isolating switch can be connected again to avoid power failure or poor contact, extend the service life of the isolating switch, and provide more time for subsequent maintenance. After the plug component 32 is inserted into the gap, the driving component 31 can drive the clamping component 35 to clamp the plug component 32 to prevent the plug component 32 from falling, thereby improving the reliability of the use of the plug component 32.

[0042] Optionally, the plug-in detection mechanism also includes a controller 4, which is electrically connected to the light receiver 22, and the controller 4 is electrically connected to the driving component 31. The controller 4 can control the driving component 31 to take action in a timely manner according to the light data received by the light receiver 22, thereby improving the degree of automation and the feedback rate during the detection process.

[0043] In this embodiment, if Figure 2 As shown, the driving assembly 31 includes a motor 311 and a first lead screw 312 which are in transmission connection, a first nut seat 313 is provided on the first lead screw 312, and the plug-in assembly 32 is provided on the first nut seat 313. After the light receiver 22 receives the light, the controller 4 controls the driving assembly 31 to move, that is, the motor 311 drives the first lead screw 312 to rotate, the first lead screw 312 drives the first nut seat 313 to move, and the first nut seat 313 drives the plug-in assembly 32 provided thereon to move toward the gap of the isolating switch, and the first nut seat 313 has high movement stability.

[0044] Furthermore, the plug-in assembly 32 includes a mounting seat 321, a translation slide 322, a linkage rod 323 and a plug-in plate 325. The mounting seat 321 is provided with a long translation slide groove 3211; the translation slide 322 is slidably arranged in the translation slide groove 3211; the linkage rod 323 is slidably arranged in the translation slide 322, and one end of the linkage rod 323 can abut against the first nut seat 313; the plug-in plate 325 is arranged on the translation slide 322. When the first nut seat 313 moves, it drives the connecting rod 323 abutting thereon to move. Since the translation slide 322 is sleeved on the connecting rod 323, and the translation slide 322 is slidably arranged in the translation slide groove 3211, when the connecting rod 323 moves, the connecting rod 323 drives the translation slide 322 to slide along the translation slide groove 3211, and at the same time, the translation slide 322 drives the plug-in piece 325 to move. The structure is simple, and the setting of the translation slide 322 improves the stability of the movement of the plug-in piece 325.

[0045] It is worth noting that the plug detection mechanism also includes a plug detector, which is arranged on the base 1 and is used to detect the position of the plug piece 325. When the plug piece 325 is plugged in, if the gap generated at the connection of the isolating switch is small and the plug piece 325 cannot be inserted into the gap, the isolating switch may still be in a connected state, which indicates that the isolating switch has a poor contact problem, so as to remind the staff to pay attention to maintenance and replacement in time; if the plug piece 325 can be inserted into the gap, that is, the gap generated at the connection of the isolating switch is large, it indicates that the isolating switch has been disconnected. By setting up a plug detector, the specific state of the opening and closing of the isolating switch can be judged according to the position of the plug piece 325 detected by the plug detector, so as to remind the maintenance personnel to repair the isolating switch in time.

[0046] In this embodiment, an arc-shaped protrusion 3231 is provided at the end of the linkage rod 323, and an arc-shaped groove 3241 matching the arc-shaped protrusion 3231 is provided on the first nut seat 313. When the translation slide 322 slides to the end of the translation groove 3211, the linkage rod 323 is separated from the first nut seat 313. That is, after the translation slide 322 contacts the end wall of the translation groove 3211, the arc-shaped protrusion 3231 of the linkage rod 323 is disengaged from the arc-shaped groove 3241 of the first nut seat 313, and the first nut seat 313 continues to move under the drive of the first lead screw 312, so that the driving assembly 31 continues to drive the clamping assembly 35 to complete the subsequent action, ensuring that the clamping action is carried out smoothly.

[0047] Optionally, a top plate 326 is provided at the end of the linkage rod 323 away from the first nut seat 313, and a positioning spring 327 is provided between the top plate 326 and the translation slide 322. After the translation slide 322 contacts the end wall of the translation slide groove 3211, the arc-shaped protrusion 3231 of the linkage rod 323 is disengaged from the arc-shaped groove 3241 of the first nut seat 313, the linkage rod 323 moves downward, and the positioning spring 327 is compressed. The positioning spring 327 can offset the impact force between the top plate 326 and the translation slide 322, prevent the top plate 326 and the translation slide 322 from colliding, and improve the reliability of the plug-in assembly 32.

[0048] Optionally, an anti-detachment seat 324 is fixedly connected to the first nut seat 313 , and an arc-shaped groove 3241 is provided on the anti-detachment seat 324 , which simplifies the processing procedure of the first nut seat 313 .

[0049] Preferably, the plug-in piece 325 is made of a conductive material. When the gap at the connection position of the isolating switch is large and the isolating switch may have been disconnected, the plug-in piece 325 can be inserted to reconnect the isolating switch under the action of the plug-in piece 325, so that the isolating switch temporarily restores a tightly connected state, avoiding power failure and poor contact, and providing time for the staff to repair the isolating switch on site when a problem is observed.

[0050] In this embodiment, if Figure 3 As shown, the plug-in piece 325 is arranged on the translation slide 322 through the first clamping assembly 33 to improve the fixing stability of the plug-in piece 325.

[0051] Exemplarily, the first clamping assembly 33 includes a first fixing seat 331, two elastic members 332 and two first clamping members 333. The first fixing seat 331 is arranged on the translation slide 322, and the first fixing seat 331 is provided with a first fixing groove 3311; the two elastic members 332 are symmetrically arranged on the two side walls of the first fixing groove 3311; the two first clamping members 333 are respectively arranged at one end of the two elastic members 332 away from the side wall, and the plug-in sheet 325 is arranged between the two first clamping members 333, and the two first clamping members 333 can clamp the plug-in sheet 325 up and down. When the plug-in sheet 325 is fixed, the elastic member 332 is compressed, so that the two first clamping members 333 clamp the plug-in sheet 325 to prevent it from falling, thereby improving the fixing stability of the plug-in sheet 325. Exemplarily, the elastic member 332 is connected to the side wall of the first fixing groove 3311 through the connecting seat 334, so as to facilitate the installation or removal of the elastic member 332.

[0052] In this embodiment, the translation slide 322 is detachably connected to the first end seat 328 , and the first clamping assembly 33 is disposed on the first end seat 328 , so as to facilitate the disassembly and assembly of the first clamping assembly 33 .

[0053] Optionally, the first nut seat 313 is fixedly connected with the driving plate 34, and the clamping assembly 35 is in driving connection with the driving plate 34. After the plug assembly 32 is inserted into the gap, the driving assembly 31 continues to drive the clamping assembly 35 to clamp the plug piece 325, thereby ensuring the continuity of the plugging action and the clamping action.

[0054] Furthermore, the driving plate 34 is provided with a driving rack 341 , and the clamping assembly 35 includes a driving gear 351 meshing with the driving rack 341 . The driving gear 351 has a large load-bearing capacity and high transmission accuracy.

[0055] Alternatively, if Figure 4 As shown, the clamping assembly 35 further includes a second clamping assembly 352, which includes a bidirectional lead screw 3521 and two second clamping members 3522 respectively screwed to the forward thread and the reverse thread of the bidirectional lead screw 3521, and the driving gear 351 is in transmission connection with the bidirectional lead screw 3521. During clamping, the driving gear 351 drives the bidirectional lead screw 3521 to rotate, so that the two second clamping members 3522 are relatively close to each other, thereby clamping the plug-in sheet 325.

[0056] Optionally, the second clamping assembly 352 further includes a second fixing seat 3523 , and the second fixing seat 3523 is provided with a second fixing groove, and both ends of the bidirectional lead screw 3521 are rotatably connected to two side walls of the second fixing groove.

[0057] Optionally, the bidirectional lead screw 3521 is provided with two second nut seats 354 , which are respectively threadedly connected to the forward thread and the reverse thread of the bidirectional lead screw 3521 , and the two second clamping members 3522 are respectively fixedly connected to the two second nut seats 354 .

[0058] Furthermore, the bidirectional lead screw 3521 is provided with a lead screw gear 355, the lead screw gear 355 and the bidirectional lead screw 3521 are coaxially arranged, and the lead screw gear 355 is connected to the driving gear 351 through a synchronous belt 353. The synchronous belt 353 has high transmission efficiency and has buffering and shock absorbing capabilities, thereby improving the reliability of transmission. In this embodiment, a synchronous pulley is coaxially arranged on the driving gear 351, and one end of the synchronous belt 353 is wound around the synchronous pulley. When the driving gear 351 rotates, the synchronous pulley rotates with it to drive the synchronous belt 353 to move. The other end of the synchronous belt 353 is wound around the lead screw gear 355. When the synchronous belt 353 moves, it drives the lead screw gear 355 to rotate, so that the two second clamping members 3522 move in a direction perpendicular to the paper surface.

[0059] Optionally, the disconnector opening and closing detection device further includes a second end seat 5 for supporting and fixing the driving gear 351 and the second clamping assembly 352 .

[0060] Optionally, a bracket is provided on the second end seat 5, and a roller is provided at the end of the bracket, and the synchronous belt 353 passes through the roller to prevent the synchronous belt 353 from affecting the arrangement of other components. Those skilled in the art can set the specific position of the bracket according to actual needs.
