Then, under the influence of gravity, the line is clamped between the two sets of fan ring plates and protected from contact with the two sets of insulation blocks. The third electric push rod is started to drive the two sets of insulation boxes to wrap the line. Then, the second air pump is started to fill the second inflatable bag structure, so that the second inflatable bag structure expands and wraps the outer wall of the partial discharge limit.

[0021] 4. During the synchronous movement of the insulating shell, the fourth fixed plate will be driven to perform buffering displacement. During the movement, the fourth fixed plate will drive the two sets of sliding rectangular blocks to slide in the slide groove. During the sliding process, they will begin to squeeze and pull one set of second compression springs respectively.

[0037] For example, Figure 4 As shown, the partial discharge monitoring assembly 3 includes a second mounting plate 301, one end of each group of the second mounting plates 301 is mounted on the outer wall of the sliding plate 205, a group of third mounting plates 302 is arranged directly above each group of the second mounting plates 301, and a number of groups of movable rings 303 are evenly spaced on the top of each group of the second mounting plates 301, a rotating rod 304 is rotatably connected inside the movable ring 303, a fixed ring 305 is sleeved on the outer wall of the rotating rod 304, and the outer wall of the fixed ring 305 is mounted on the bottom of the third mounting plate 302, a first motor 306 is mounted on the top of the second mounting plate 301, and the output end of the first motor 306 is transmission-connected to the rotating rod 304, an ultrasonic sensor 307 is mounted on the top of the third mounting plate 302, and a UHF sensor 308 is mounted on the top edge of the third mounting plate 302.
[0038] In order to expand the monitoring effect of the ultrasonic sensor 307 and the ultra-high frequency sensor 308, the first motor 306 is started to drive the rotating rod 304 to rotate. The rotating rod 304 rotates in the movable ring 303 and drives the fixed ring 305 to rotate. The fixed ring 305 rotates and drives the ultrasonic sensor 307 and the ultra-high frequency sensor 308 on the third mounting plate 302 to rotate, thereby expanding the flexibility of adjusting the monitoring angle.
[0039] For example, Figure 5 and Figure 6 As shown, the auxiliary component 4 includes a circular body 401, the outer wall of each group of the circular bodies 401 is mounted on a side wall of the sliding plate 205, a group of first inflatable bag structures 402 is mounted on the inner wall of each group of the circular bodies 401, a group of first air pumps 403 is mounted on the outer wall of each group of the circular bodies 401, the output end of each group of the first air pumps 403 passes through the circular body 401 and is connected to the input end of the first inflatable bag structure 402, a group of frosted pads is mounted on the outer wall of each group of the first inflatable bag structure 402, two groups of fan ring plates 404 are symmetrically mounted on one side wall of each group of the circular bodies 401, a group of insulating blocks 405 are mounted on one side wall of each group of the fan ring plates 404, and a group of third fixing plates 40 are mounted on the outer wall of each group of the circular bodies 401. 6. A group of sliding grooves 407 are provided on the bottom of each group of the third fixed plates 406, and two groups of mounting blocks 408 are symmetrically installed on the inner walls on both sides of each group of the third fixed plates 406. A group of connecting pipes 409 are installed on one side wall of each group of the mounting blocks 408, and one end of a group of second compression springs 410 are installed on one side wall of each group of the mounting blocks 408. Each group of the second compression springs 410 is movably sleeved on the outer wall of the connecting pipe 409, and a group of sliding rectangular blocks 411 are installed on the other end of each group of the second compression springs 410. Each group of the sliding rectangular blocks 411 is movably sleeved on the outer wall of the connecting pipe 409. A fourth fixed plate 412 is connected between the bottoms of the two groups of sliding rectangular blocks 411, and a group of baffles 413 are installed on the bottom of each group of the fourth fixed plates 412.
[0040] To prevent the circuits in different spaces from being disturbed, the fourth fixed plate 412 will be driven to perform buffering displacement during the synchronous movement of the insulating shell. During the movement, the fourth fixed plate 412 will drive the two groups of sliding rectangular blocks 411 to slide in the slide groove. During the sliding process, they will begin to squeeze and pull one group of second compression springs 410 respectively. When the circuit track returns to normal, the two groups of second compression springs 410 will begin to rebound and reset, avoiding the problem of disturbing the line while improving the auxiliary effect of three-dimensional line monitoring.
[0041] For example, Figure 7As shown, the compatible component 5 includes a second electric push rod 501, the top of each group of the second electric push rods 501 is installed on the bottom of the fourth fixed plate 412, and a group of first insulating shells 502 are installed on the output end of each group of the second electric push rods 501, and two groups of second motors 503 are symmetrically installed on one side wall of each group of the first insulating shells 502, wherein the output end of one group of the second motors 503 is connected to the second insulating shell 504 in a transmission manner, and the output end of the other group of the second motors 503 is connected to the third insulating shell 505 in a transmission manner.
[0042] When the high-voltage switchgear module is performing ultra-high frequency partial discharge online rapid monitoring, the mounting frame 101 is first installed on the inner wall of the switchgear, and then several groups of circuits are sequentially sleeved in the circular body 401, thereby expanding the space between the several groups of lines, avoiding the entanglement problem, and improving the rapid positioning effect of subsequent partial discharge monitoring. Subsequently, the first air pump 403 is started to fill the first inflatable bag structure 402, so that the frosted cushion layer fits on the outer wall of the circuit, and the first electric push rod 207 is started to push the second electromagnetic block 208 to magnetically connect with the first electromagnetic block 206. Subsequently, the first electric push rod 207 is started to push the sliding plate 205 away from the first mounting plate 203. During the movement, the first compression spring 204 is pulled, and during its movement, the frosted cushion layer on the first inflatable bag structure 402 is driven to clean impurities on the outer wall of the circuit, thereby expanding the monitoring of the circuit by the ultrasonic sensor 307 and the ultra-high frequency sensor 308, and avoiding the problem of incomplete monitoring due to impurities blocking the circuit.
[0043] Before the circular body 401 moves, the second electric push rod 501 is started to push the inner wall of the first insulating shell 502 to contact the outer wall of the bottom circuit, and one group of the second motors 503 is started to drive the inner wall of the third insulating shell 505 to contact the outer wall of a group of circuits adjacent to it, and then one group of the second motors 503 is started to drive the second insulating shell 504 to rotate. During the rotation of the second insulating shell 504, the inner wall is driven to contact the outer wall of the bottom circuit that contacts the inner wall of the first insulating shell 502, forming a semi-wrapped state for it. While the circular body 401 moves, the insulating shell is driven to wrap the outer wall of the circuit and advance synchronously, so that the bottom circuit can also be monitored by the output range radiation of the ultrasonic sensor 307 and the ultra-high frequency sensor 308, thereby improving the combined radiation range and the line combing and resolution effect.
[0044] For example, Figure 8As shown, the protective insulation assembly 6 includes a fifth fixed plate 601, one end of each group of the fifth fixed plates 601 is mounted on a side wall of the baffle 413, a group of third electric push rods 602 is mounted on one side wall of each group of the fifth fixed plates 601, a group of insulating boxes 603 are mounted on the output end of each group of the third electric push rods 602, a group of vacuum pumps 604 are mounted on the outer wall of each group of the insulating boxes 603, a group of fitting fan rings 605 are mounted on the top of each group of the insulating boxes 603, a group of second inflatable bag structures 606 are mounted on the inner wall of each group of the fitting fan rings 605, a group of second air pumps 607 are mounted on the outer wall of each group of the fitting fan rings 605, and the output end of each group of the second air pumps 607 passes through the fitting fan rings 605 and is connected to the second air pump 607.
[0045] When the ultrasonic sensor 307 and the UHF sensor 308 detect that there is a partial discharge in the circuit, the first air pump 403 is started to quickly fill the first inflatable bag structure 402, so that the first inflatable bag structure 402 wraps and limits the outer wall of the circuit, and then breaks away from the magnetic connection between the first electromagnetic block 206 and the second electromagnetic block 208. When the first compression spring 204 senses that the pressure disappears, it drives the circuit and the switch cabinet module central control structure to break away from the electrical connection state. Then, under the influence of gravity, the circuit will be stuck between the two sets of fan ring plates 404 and the two sets of insulation. Block 405 performs contact protection. In order to improve the protection effect on the partial discharge circuit, the third electric push rod 602 is started to drive the two groups of insulation boxes 603 to wrap the line, and then the second air pump 607 is started to fill the second inflatable bag structure 606, so that the second inflatable bag structure 606 expands and wraps the outer wall of the partial discharge limiter. Then the vacuum pump 604 is started to evacuate the air in the two groups of insulation boxes 603, so that the partial discharge line has no medium to conduct electricity, which improves the protection effect of the device and improves the online rapid monitoring effect of ultra-high frequency partial discharge of the high-voltage switchgear module.
[0046] When the ultrasonic sensor 307 and the UHF sensor 308 detect partial discharge in the circuit, the circuit is disconnected from the central control structure of the switch cabinet module. Then, under the influence of gravity, the line will be stuck between the two sets of fan ring plates 404 and protected from contact with the two sets of insulating blocks 405. The third electric push rod 602 is started to drive the two sets of insulating boxes 603 to wrap the line, and then the second air pump 607 is started to fill the second inflatable bag structure 606, so that the second inflatable bag structure 606 expands and wraps the outer wall of the partial discharge limit. Then, the vacuum pump 604 is started to evacuate the air in the two sets of insulating boxes 603, so that the partial discharge line has no medium to conduct electricity, thereby improving the protection effect of the device and the online rapid monitoring effect of ultra-high frequency partial discharge of the high-voltage switch cabinet module.
[0047] Several groups of circuits are sequentially sleeved in the annular body 401, which expands the space between the several groups of lines, avoids the entanglement problem, and improves the rapid positioning effect of subsequent partial discharge monitoring. Then, the frosted pad is attached to the outer wall of the circuit, and the first electric push rod 207 is started to push the sliding plate 205 to move away from the first mounting plate 203. During the movement, the first compression spring 204 is pulled, and during its movement, the frosted pad on the first inflatable bag structure 402 is driven to clean the outer wall of the circuit for impurities, thereby expanding the monitoring of the circuit by the ultrasonic sensor 307 and the ultra-high frequency sensor 308, and avoiding the problem of incomplete monitoring due to impurities blocking.
[0048] Start the second electric push rod 501 to push the inner wall of the first insulating shell 502 to contact the outer wall of the bottom circuit, and start one of the second motors 503 to drive the inner wall of the third insulating shell 505 to contact the outer wall of a group of circuits adjacent to it, and then start one of the second motors 503 to drive the second insulating shell 504 to rotate. During the rotation of the second insulating shell 504, the inner wall is driven to contact the outer wall of the bottom circuit that contacts the inner wall of the first insulating shell 502, forming a semi-wrapped state. While the annular body 401 moves, it drives the insulating shell to wrap the outer wall of the circuit and advance synchronously, so that the bottom circuit can also be monitored by the output range radiation of the ultrasonic sensor 307 and the ultra-high frequency sensor 308, thereby improving the combined radiation range and the line combing and resolution effect.
[0049] During the synchronous movement of the insulating shell, the fourth fixed plate 412 will be driven to perform buffering displacement. During the movement, the fourth fixed plate 412 will drive the two groups of sliding rectangular blocks 411 to slide in the slide groove, and will begin to squeeze and pull one group of second compression springs 410 respectively during the sliding process. When the circuit track returns to normal, the two groups of second compression springs 410 will begin to rebound and reset, avoiding the problem of disrupting the line while improving the auxiliary effect of three-dimensional line monitoring; in order to expand the monitoring effect of the ultrasonic sensor 307 and the ultra-high frequency sensor 308, the first motor 306 can be started to drive the ultrasonic sensor 307 and the ultra-high frequency sensor 308 to rotate, thereby expanding the flexibility of adjusting the monitoring angle.
