DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely explained below with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application.

[0040] The starting of the electric sliding platform 402 drives the two groups of insulating fan rings 502 to the two ends of the high-voltage cable, and then the second motor 409 is started to drive the threaded rod 405 to rotate, and the threaded rod 405 rotates while driving 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 towards each other, and then the two groups of insulating fan rings 502 are driven to fit and limit, and then the first air pump 504 is started to fill the inflatable bag structure 503, so that the inflatable bag structure 503 expands to wrap the outer wall of the high-voltage cable, and then the first electric push rod 403 is started to drive the distance to perform fault ranging work. During the movement, the inflatable bag structure 503 is used to remove impurities on the surface of the cable, so that the positioning effect is more accurate, and the auxiliary positioning effect of the device is improved.

When the cable surface has frost, the heating box 519 is started to send hot air to the output pipe 520, so that the hot air in the inflatable bag structure 503 melts the surface of the cable. During the process, high-voltage direct current is applied to the high-voltage generator 525, and then the voltage distribution and current change of the cable are analyzed to accurately locate the breakpoint or insulation damage position, and the positioning instrument 505 and the path instrument 506 are used for positioning and ranging work.

[0043] When encountering a cable surface protrusion, a compression spring 524 is used for buffering to avoid damage to the cable surface; when facing high-temperature or low-temperature environments, the cable surface is cooled and heated; during the process, high-voltage direct current is applied through the high-voltage generator 525, and then the breakpoint or insulation damage position is accurately positioned by analyzing the cable voltage distribution and current change, and then the positioning instrument 505 and the path instrument 506 are used for positioning and ranging work, the working precision of the positioning and ranging work is improved by the constant temperature working environment, the buffering protection effect is improved, and the working effect of the positioning and ranging device is improved.

[0044] When treating high-voltage cable surface impurities, first make the two groups of liquid storage rings 511 fit and clamp, then spray the cleaning solution placed in one of the groups of liquid storage rings 511 through the micro pump 512, and push and spray through the second electric push rod 510, and after spraying, the surface is cleaned by the inflatable bag structure 503, improving the treatment effect of the cable surface, and when the cable surface is worn or the like, the raw material filling of the liquid storage ring 511 can be performed through the repair agent placement box 514, and then the micro pump 512 is started to spray and smear, and then the inflatable bag structure 503 with heat is used for rapid condensation, improving the repair treatment effect of the cable surface.

[0045] When the high-voltage cable is positioned and ranged, first determine the installation point, then push the two groups of limit blocks 106 in opposite directions, the two groups of limit blocks 106 slide in the slide 103 while starting to squeeze the two groups of extension springs 105, then make the installation point between the two groups of limit blocks 106, then disengage the two groups of limit blocks 106, when the two groups of extension springs 105 feel the pressure disappears, start to rebound, drive the two groups of limit blocks 106 to elastically limit the installation point, and the value is monitored through the pressure sensor 107, improving the elastic compatible limiting effect and the convenient clamping effect.

[0046] The starting electric sliding table 402 drives two groups of insulating fan rings 502 to descend to both ends of the high-voltage cable, and then the second motor 409 is started to drive the threaded rod 405 to rotate. The threaded rod 405 rotates while driving the two groups of sliding blocks 407 to slide in the sliding cavity 406. In the sliding process, the two groups of insulating blocks 408 are driven to move towards each other, and then the two groups of insulating fan rings 502 are driven to fit and limit. Then the first air pump 504 is started again to fill the air bag structure 503, so that the air bag structure 503 expands to wrap the outer wall of the high-voltage cable. Then the first electric push rod 403 is started to drive the distance to perform fault ranging work. In the moving process, the cable surface is treated by the air bag structure 503 to remove impurities, so that the positioning effect is more accurate, and the auxiliary positioning effect of the device is improved.
