Abstract

The invention provides the comprehensive detection method of a composite insulator aging degree. The method is characterized by through obtaining the measuring results of an infrared spectrum analysismethod, a thermal stimulation current TSC analysis method, a hyperspectral spectrogram analysis method and a surface charge density method, using an BP neural network algorithm to optimize differenttest methods to acquire the weight of a test result; obtaining the comprehensive aging degree of a composite insulator; and acquiring the remaining service life of composite insulator aging through anormalization method. The aging degree of the composite insulator is acquired through integrating various methods, the comprehensive detection of the aging degree of the composite insulator is realized, the aging degree of the composite insulator can be accurately measured, and the remaining service life of the composite insulator is predicted. More accurate technical support is provided for the operation and maintenance personnel of a power transmission line to timely replace the composite insulator with the severe aging degree, and the safe and reliable operation of the power transmission line is ensured.

Description

technical field [0001] The application belongs to the technical field of high-voltage composite insulators, and in particular relates to a comprehensive detection method for the aging degree of composite insulators. Background technique [0002] At present, composite insulators are widely used in the insulation of transmission lines in power systems because of their advantages such as high mechanical strength, high pollution flashover voltage, light weight, and simple operation and maintenance. However, due to the influence of the environment around the transmission line, including ultraviolet rays, temperature and humidity, pollution and corona, etc., composite insulators will experience varying degrees of aging. The aging of composite insulators is mainly manifested in the brittleness, pulverization and damage of shed slices, and even the breakage of mandrels. These phenomena will seriously affect the normal operation of composite insulators, and then affect the safe and r...
