Then start the first electric push rod to push the fault distance measurement. During the movement, the cable surface is cleaned by the inflatable bag structure, which makes the positioning effect more accurate and improves the auxiliary positioning effect of the device.

While the two sets of limit blocks 106 slide in the slide 103, they begin to squeeze the two sets of tension springs 105, and then the installation point is located between the two sets of limit blocks 106.

[0039] For example, Figure 5 、 Figure 6 、 Figure 7 and Figure 8As shown, the positioning and ranging component 5 includes an insulating plate 501, the top of each group of the insulating plates 501 is mounted on the bottom of the insulating block 408, a group of insulating fan rings 502 are mounted on the bottom of each group of the insulating plates 501, a group of inflatable bag structures 503 are mounted on the inner wall of each group of the insulating fan rings 502, a group of first air pumps 504 are mounted on each group of the insulating fan rings 502, the output end of each group of the first air pumps 504 is connected to the input end of the inflatable bag structure 503, a group of locators 505 are mounted on one side wall of each group of the insulating plates 501, and a group of path meters are mounted on the side wall of each group of the insulating plates 501 away from the locator 505. 506, a group of refrigerators 507 are installed on one side wall of each group of insulating fan rings 502, and each group of refrigerators 507 is connected to one end of a group of vacuum tubes 508, and the other end of each group of vacuum tubes 508 is connected to the inflatable bag structure 503, and a group of second air pumps 509 are installed on the outer wall of each group of vacuum tubes 508, and two groups of second electric push rods 510 are symmetrically installed on both side walls of each group of insulating fan rings 502, and a group of liquid storage rings 511 are installed on the output end of each group of second electric push rods 510, and a number of groups of micro pumps 512 are evenly spaced on each group of liquid storage rings 511, and each group of liquid storage rings 511 is symmetrically opened. There are two groups of liquid accumulation grooves 513, one of which is connected to a repair agent placement box 514 on the outer wall of the liquid storage ring 511 of one group. A group of fitting rings 515 are provided in each group of the inflatable bag structure 503. The outer wall of each group of the fitting rings 515 is installed on the insulating fan ring 502. A group of first mounting plates 516 are installed on one side wall of each group of the fitting rings 515. A group of sleeve pipes 517 are installed on one side wall of each group of the first mounting plates 516. A group of sliding rods 518 are slidably connected in each group of the sleeve pipes 517. A group of heating boxes 519 are installed on one side wall of each group of sliding rods 518. Each group of heating boxes 519 is evenly spaced and connected to a number of groups of delivery pipes. Outlet pipe 520, a group of third electric push rods 521 are installed on one side wall of each group of the first mounting plates 516, a group of first electromagnetic blocks 522 are installed on the output end of each group of the third electric push rods 521, a group of second electromagnetic blocks 523 are installed on one side wall of each group of the heating boxes 519, the first electromagnetic blocks 522 are magnetically connected to the second electromagnetic blocks 523, one end of two groups of compression springs 524 are symmetrically installed on the edge of one side wall of each group of the first mounting plates 516, the other end of each group of the compression springs 524 is installed on one side wall of the heating box 519, and a group of high-voltage generators 525 are installed on one side wall of each group of the fitting rings 515.

[0040] Start the electric slide 402 to drive the two groups of insulating fan rings 502 to descend to the two ends of the high-voltage cable, and then start the second motor 409 to drive the threaded rod 405 to rotate. While the threaded rod 405 rotates, it drives the two groups of sliding blocks 407 to slide in the sliding cavity 406. During the sliding process, the two groups of insulating blocks 408 are driven to move toward each other, and the two groups of insulating fan rings 502 are driven to fit and limit. Then start the first air pump 504 to fill the inflatable bag structure 503, so that the inflatable bag structure 503 wraps the outer wall of the high-voltage cable after expansion, and then start the first electric push rod 403 to perform distance pushing fault ranging. During the movement, the cable surface is cleaned by the inflatable bag structure 503, which makes the positioning effect more accurate and improves the auxiliary positioning effect of the device.

[0041] Before filling the air bag structure, start the third electric push rod 521 to drive the first electromagnetic block 522 to magnetically connect with the second electromagnetic block 523, and then start the third electric push rod 521 to drive the heating box 519 on the second electromagnetic block 523 to move toward the first mounting plate 516. During the movement, the compression spring 524 begins to be squeezed. Then, after the air bag structure 503 wraps the cable, it breaks away from the magnetic connection state of the two sets of electromagnetic blocks. After the compression spring 524 senses the disappearance of the pressure, it drives the heating box 519 to contact the outer wall of the cable. Then, during the movement detection process, when the cable surface is bulged, it is buffered by the compression spring 524, avoiding the problem of wear on the cable surface and extending the service life of the device. When facing a high temperature environment, start the refrigerator 50 7. Fill the vacuum tube 508 with cold air, then start the second air pump 509 to suck the cold air from the vacuum tube 508 into the inflatable bag structure 503 to cool the cable surface. When the cable surface is frosted, start the heating box 519 to deliver hot air to the output tube 520, so that the hot air in the inflatable bag structure 503 melts the cable surface. During the process, high-voltage direct current is applied by the high-voltage generator 525, and then the breakpoint or insulation damage position is accurately located by analyzing the cable voltage distribution and current changes. The positioning and ranging work is then carried out in conjunction with the locator 505 and the path meter 506. The working accuracy of the positioning and ranging is improved through the constant temperature working environment, and the buffer protection effect is improved while the working effect of the positioning and ranging device is improved.

[0042] When treating impurities on the surface of a high-voltage cable, the two groups of liquid storage rings 511 are first fitted and clamped together, and then the cleaning solution placed in one of the liquid storage rings 511 is sprayed out by the micro pump 512, and the second electric push rod 510 is used to push and spray. After spraying, the surface is cleaned by friction through the inflatable bag structure 503, thereby improving the treatment effect of the cable surface. When wear and tear occur on the cable surface, the liquid storage ring 511 can be filled with raw materials through the repair agent placement box 514, and then the micro pump 512 is started for spraying and coating, and subsequently the inflatable bag structure 503 with heat is used for rapid condensation, thereby improving the repair treatment effect of the cable surface.

[0043] When encountering bulges on the cable surface, the compression spring 524 is used for buffering, avoiding the problem of wear on the cable surface; when facing a high temperature environment or a low temperature environment, the cable surface is cooled and heated; during the process, after applying high voltage direct current through the high voltage generator 525, the breakpoint or insulation damage position is accurately located by analyzing the cable voltage distribution and current changes, and the positioning instrument 505 and the path meter 506 are used to perform positioning and ranging work. The constant temperature working environment is used to improve the working accuracy of positioning and ranging, improve the buffering protection effect, and improve the working effect of the positioning and ranging device.

[0044] When treating impurities on the surface of a high-voltage cable, the two groups of liquid storage rings 511 are first fitted and clamped, and then the cleaning solution placed in one of the groups of liquid storage rings 511 is sprayed out by the micro pump 512, and the second electric push rod 510 is used to push and spray. After spraying, the surface is cleaned by friction through the inflatable bag structure 503, which improves the treatment effect of the cable surface. When wear and tear occur on the cable surface, the liquid storage ring 511 can be filled with raw materials through the repair agent placement box 514, and then the micro pump 512 is started for spraying and coating, and then it is quickly condensed by the hot inflatable bag structure 503, which improves the repair treatment effect of the cable surface.

[0045] When the high-voltage cable is performing fault location and ranging, the installation point is first determined, and then the two sets of limit blocks 106 are pushed to move in opposite directions. While the two sets of limit blocks 106 slide in the slide 103, they begin to squeeze the two sets of tension springs 105, and then the installation point is located between the two sets of limit blocks 106. Then, the push on the two sets of limit blocks 106 is released. When the two sets of tension springs 105 feel that the pressure disappears, they begin to rebound, driving the two sets of limit blocks 106 to elastically limit the installation point, and the pressure sensor 107 is used for numerical monitoring, which improves the elastic compatibility limiting effect while improving the easy-to-install clamping effect.

[0046] Start the electric slide 402 to drive the two groups of insulating fan rings 502 to descend to the two ends of the high-voltage cable, and then start the second motor 409 to drive the threaded rod 405 to rotate. While the threaded rod 405 rotates, it drives the two groups of sliding blocks 407 to slide in the sliding cavity 406. During the sliding process, the two groups of insulating blocks 408 are driven to move toward each other, and the two groups of insulating fan rings 502 are driven to fit and limit. Then start the first air pump 504 to fill the inflatable bag structure 503, so that the inflatable bag structure 503 wraps the outer wall of the high-voltage cable after expansion, and then start the first electric push rod 403 to perform distance pushing fault ranging. During the movement, the cable surface is cleaned by the inflatable bag structure 503, which makes the positioning effect more accurate and improves the auxiliary positioning effect of the device.
