Electric leakage detector for high-voltage transmission line

Abstract

The invention discloses a high-voltage power transmission line electric leakage detector which comprises a box body, a box door is arranged on the box body, a folding rod is arranged between the box door and the box body, an analysis processing module, a wireless receiving and transmitting module and a power supply module are arranged in the box body, and the high-voltage power transmission line electric leakage detector further comprises a walking mechanism and a clamping part. The two walking mechanisms are arranged on the portions, on the two sides of the box door, of the box body respectively, the clamping part comprises two detection clamps of an arc-shaped structure, and the inner sides of the detection clamps are provided with arc-shaped magnetic assemblies and guide mechanisms. According to the invention, the detection clamp is arranged, the magnetic assembly is arranged on the inner side of the detection clamp, the magnetic assembly is formed by sequentially splicing a plurality of magnetic blocks, and two adjacent magnetic blocks can rotate, so that the magnetic assembly can be bent, and the magnetic assembly is moved through the guide mechanism, so that the inner diameter size of a circular structure formed by the magnetic assembly is changed; therefore, the detector is provided with the adjustable magnetic assembly, so that the detector can detect different numbers of lines.

Description

technical field [0001] The invention relates to the technical field of leakage detection, in particular to a leakage detector of a high-voltage transmission line. Background technique [0002] In the operation and maintenance of the power grid, it is necessary to check the leakage of the power line. Most of the leakage detectors used in the prior art are of the open type. This open leakage detector can be clamped on the cable to measure the leakage current, but since there may be more than one line to be detected, it may be necessary to use leakage detectors of different calibers for this situation. All instruments need to be opened separately, which leads to higher production costs. At the same time, for lines with high erection height, it is inconvenient for manual hand-held equipment to detect, and there is a high safety hazard. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to propose a leakage detector for high-voltage transmission lines i...

This open-type leakage detector can be clamped on the cable to measure the leakage current, but since there may be more than one line to be detected, it may be necessary to use different caliber leakage detectors for this situation, each caliber of leakage detection Both instruments need to be molded separately, which leads to higher production costs. At the same time, for lines with high erection heights, manual hand-held equipment detection is inconvenient, and there are high potential safety hazards.
