Corona ultraviolet detecting device capable of locating and measuring distance

Abstract

The invention discloses a corona ultraviolet detecting device capable of locating and measuring distance. The corona ultraviolet detecting device capable of locating and measuring the distance comprises an ultraviolet camera lens, an ultraviolet detector, a signal processing circuit, a data displayer and a laser viewer. The optical axis of the ultraviolet camera lens and the optical axis of the ultraviolet detector are the same. A laser device base seat is installed on the ultraviolet camera lens in a sleeved mode. A visible laser and a laser back wave probe are installed on the laser device base seat. The laser back wave probe is located right above the visible laser. The laser back wave probe is close to the visible laser. The visible laser is electrically connected with the signal processing circuit through a laser distance measurement circuit. The laser back wave probe is connected with the signal processing circuit through the laser distance measurement circuit. Outgoing light beams of the visible laser are close to and parallel to the optical axis of the ultraviolet lens. The corona ultraviolet detecting device capable of locating and measuring the distance has the advantages of being capable of rapidly finding an appropriate portion, where discharging occurs, of an insulator, or finding which insulator is discharged, achieving the aims that discharging positions of the insulator are located, being capable of obtaining parameters of distance measurement, and obtaining ultraviolet radiation intensity by combination of the distance measurement.

Description

technical field [0001] The invention relates to a corona ultraviolet detector, in particular to a corona ultraviolet detector capable of positioning and ranging. Background technique [0002] With the rapid development of my country's power grid scale, the problem of partial discharge faults in power equipment has become increasingly prominent. In the early stage of partial discharge fault, it generally manifests as corona discharge. Corona discharge refers to a self-sustained discharge phenomenon caused by partial ionization of surrounding gas (usually air) after the electric field strength near the electrode exceeds a certain value. Corona is a high-voltage pulse discharge, which will be accompanied by the generation of plasma during the discharge process. It will cause chemical reactions in the air, produce ozone and nitrogen oxide and other products, cause insulation corrosion and damage to electrical equipment, and cause serious accidents and power grid paralysis.

AI Technical Summary

Problems solved by technology

[0005] However, due to the immature research on high-sensitivity solar-blind ultraviolet imaging devices in my country, and the high-performance foreign imaging devices are very expensive, our country is facing great difficulties in the practical research of corona ultraviolet imagers.

However, using unit (non-imaging) detection method to detect the intensity of corona ultraviolet radiation is a more suitable technology, the technical difficulty is relatively low, and the development cost of the instrument is much lower than that of the corona ultraviolet imager. However, many unit ultraviolet detection technologies currently Missing targeting system

The consequence is that it is impossible to judge which part of the insulator has corona discharge, and even which insulator has corona discharge cannot be judged clearly
