Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-voltage line maintenance, and in particular to a 10kV line grounding fault positioning device and positioning identification system. BACKGROUND

[0002] The 10kV line in operation often has tripping accidents due to natural disasters such as thunder, wind, snow, and other factors such as external force and environmental pollution. Among them, the most common is the 10kV line grounding fault. The most difficult to find in the type of line grounding fault is the small current grounding line tripping. The reason is mostly that the insulation level of the line and the equipment (such as porcelain bottles, lightning arresters, etc.) is reduced, causing leakage current and causing line grounding tripping. Because the installation position of the porcelain bottle, lightning arrester, etc. is relatively high, and the position of the leakage current is particularly hidden (such as needle type base discharge, or discharge caused by reduced density inside the porcelain bottle, etc.), it brings great difficulty to the first-line personnel to find the fault reason.

[0003] The traditional method for finding is the overall insulation shaking method of the line, but this method is suitable for 10kV lines with shorter length, fewer distribution transformers, and no cross-over other 10kV and above lines. Therefore, this method is too limited, and it is not obvious for complex lines and larger lines in mountainous areas. Moreover, the existing detection method requires the worker to operate on the high ground, which has certain safety hazards. In addition, during the detection process, the worker needs to read the equipment data to know the fault problem, and the equipment cannot directly indicate the fault. SUMMARY

[0034] Specifically, it comprises an AC / DC detection assembly 100, a power transmission assembly 200, and a connecting assembly 300.

[0035] The AC / DC leakage sensor 101 comprises a body 101a, a socket 101b fixedly arranged at the upper end of the body 101a, and a trigger 101c arranged at one side of the body 101a for driving the socket 101b to open and close the clamping, so as to facilitate the clamping of the electric wire and the switching of the position on the electric wire.
