Analysis method for detecting insulation state of closed space based on C-band ultraviolet rays

Abstract

The invention discloses an analysis method for detecting the insulation state of a closed space based on C-band ultraviolet rays. The method comprises the specific steps that S1, in a to-be-detected closed space area, the monitoring of the C-band ultraviolet photon quantity and monitoring of the ozone content are achieved, the data of ultraviolet photon quantity monitoring and ozone content monitoring are obtained, and the acquired data is transmitted to a computer for data processing; S2, the computer carries out grouping calculation on the obtained data, each group of data is regarded as a coordinate parameter, the distance between two adjacent coordinate points, namely the similarity of the coordinate points, is calculated, and multiple groups of similarity calculation results are obtained after similarity calculation; and S3, integral calculation is performed on a plurality of groups of similarity calculation results, a stability coefficient of each group of data is calculated, and an average value of the plurality of groups of stability coefficients is calculated so as to judge the insulation stability of the monitored point. The advantage of the method is that the method can provide a reference basis of insulation data for the stable operation of power equipment.

Description

technical field [0001] The invention relates to the field of intelligent analysis, in particular to an analysis method for detecting the insulation state of a confined space based on C-band ultraviolet rays. Background technique [0002] For a long time, the insulation monitoring of power equipment has been paid much attention. Every year, equipment failures and tripping accidents caused by insulation problems occur, which bring huge losses to the power grid and users. For the insulation monitoring and discrimination methods of power equipment, from offline insulation monitoring to ultraviolet imaging analysis, although certain problems have been solved, the results obtained are still not ideal. At present, ultraviolet imaging analysis technology is recognized as an insulation discrimination method with relatively accurate monitoring accuracy. It uses the ultraviolet spectrum generated by corona to realize corona imaging, and can directly observe the insulation state of the ...

At present, ultraviolet imaging analysis technology is recognized as an insulation discrimination method with relatively accurate monitoring accuracy. It uses the ultraviolet spectrum generated by corona to realize corona imaging, and can intuitively observe the insulation state of the device, but it is limited by its equipment. Expensive, ultraviolet imaging analysis technology has not been fully popularized, let alone applied to equipment for online monitoring and discriminant analysis
