A high-voltage cable defect rapid diagnosis device

Abstract

The invention discloses a high-voltage cable defect rapid diagnosis device. The device structurally comprises an industrial personal computer, a fixing mechanism and a filter, wherein the industrial personal computer is electrically connected with the filter, the fixing mechanism is sleeved with the left side of the industrial personal computer, the fixing mechanism comprises a movable clamping opening, a closing cover, a clamping groove, a rotating body and a fixing end, and the outer surface of the fixing end is provided with threads. According to the high-voltage cable defect rapid diagnosis device, a net groove edge arranged in the inner edge of the clamping groove and the outer surface of the cable are tightly attached together, when the cable is arranged inside the fixing mechanism,the soil on the outer surface of the cable is scraped to fall into a confluence cavity through the net groove edge, and the soil on the surface of the cable can be further separated through the arranged net groove edge, so that the soil cannot be left in the fixing mechanism, and the later-stage fixation stability is not influenced.

Description

technical field [0001] The invention relates to the field of cable technology, in particular to a high-voltage cable defect rapid diagnosis device. Background technique [0002] The application of high-voltage cables in power systems is becoming more and more extensive. Ensuring the safe operation of cable lines is a basic requirement for the operation of power systems. With the continuous advancement of economy and technology, people's demand for electricity is increasing. The requirements for high-voltage cables have also been improved. my country's electric power industry is developing faster and faster under the pressure of competition in the new era, and the demand for high-voltage cables by electric power companies is also increasing. Because the construction method of underground directly buried high-voltage cables is more economical, it is widely adopted by various power companies. But its disadvantage is that after running for a period of time, the sheath of the hig...

Problems solved by technology

But its disadvantage is that after running for a period of time, the sheath of the high-voltage cable directly buried in the ground is often bitten by mice or damaged by other external forces, resulting in a drop in insulation, and then the one-point grounding of the shielding layer is changed to multi-point grounding. The phenomenon of circulating heat can easily cause the cable to be burned, thereby causing electrical accidents

[0003] When the prior art detects buried high-voltage cables, because they are often buried underground, there will be a lot of soil left on the outer surface of the cable, resulting in the fixed structure of the high-voltage cable detector, and a large amount of soil will be contaminated when the cable is fixed. After one end is fixed for a long time, it will not only affect the stability of the later stage, but also be affected by the solidification of the soil, which will easily cause difficulty in disassembly. It also needs to be cleaned when it is retrieved, which is time-consuming and laborious.
