A corona discharge detection device for high-voltage power transmission and transformation projects

Abstract

The invention relates to the technical field of power detection and discloses a corona discharge detection device for a high voltage transmission and transformation project. The device includes a body. A display screen is mounted flexibly on the front surface of the body. According to the invention, through the arranged squeezing cylinder and a piston rod in sliding connection with the inner sideof the squeezing cylinder, cleaning liquid in the squeezing cylinder can flow into a sprayer pipe through a connection pipe after the piston rod is pressed. Through a sliding groove arranged in a mounting fixing rod, movement of the sprayer pipe in the sliding groove is realized, so that an aim that the sprayer pipe moves to the upper side of a probe and sprays the cleaning liquid through a sprayer connected to the sprayer pipe so as to clean the sprayer is realized. Through a liquid storage tank corresponding to an injection pipe and fixedly mounted on the support rod, supply of the cleaningliquid to the squeezing cylinder through connection of the liquid storage tank and the injection pipe is realized. Therefore, realization of aim of self cleaning of the corona discharge detection device for the high voltage transmission and transformation project is facilitated.

Description

technical field [0001] The invention relates to the technical field of electric power detection, in particular to a corona discharge detection device for high-voltage power transmission and transformation projects. Background technique [0002] Corona discharge is the local self-sustained discharge of the gas medium in the uneven electric field, the most common form of gas discharge, near the tip electrode with a small curvature radius, because the local electric field strength exceeds the ionization field strength of the gas, the gas is ionized and When the corona occurs, light can be seen around the electrode, accompanied by a hissing sound. The corona discharge can be a relatively stable discharge form, or it can be a process of uneven electric field gap breakdown. early stages of development. [0003] With the development of the times and science and technology, the advancement of science and technology has also promoted the technological progress of the corona discharg...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a corona discharge detection device for high-voltage power transmission and transformation projects, which has the advantages of good protection effect and self-cleaning, and solves the problem of corona discharge detection devices used in current high-voltage power transmission and transformation projects. It is a manual hand-held detection device for detection without a stable protective structure, so it is often easy to cause damage to the detection device. At the same time, the corona discharge detection device for high-voltage power transmission and transformation projects cannot clean the detection lens.
