Abstract

The invention discloses a method for detecting the aging degree of composite insulators based on hyperspectral technology, which can realize non-contact, rapid and non-damaging detection of composite insulators; can realize information mapping from hyperspectral spectral lines to aging degree from various characteristic parameters; The established model is used to analyze the aging degree of insulators, provide guidance and reference for replacing insulators with high aging degrees, and improve the stability and safety of transmission line power supply.

Description

technical field [0001] The invention belongs to the technical field of composite insulators, and in particular relates to a method for detecting the aging degree of composite insulators based on hyperspectral technology. Background technique [0002] Insulation aging is an important cause of external insulation flashover failure. Composite insulators of transmission lines face various harsh environments during operation, which can break some chemical bonds of silicone rubber material polymers, change the group content, and change the physical and chemical properties of the material, which directly manifests as the decrease of hydrophobicity on the surface of the insulator and the occurrence of turtles. Cracking, pulverization, increased surface roughness, etc., reduce the flashover voltage, easily cause grid failure, and cause great economic losses. Therefore, accurate acquisition of insulator surface aging degree is an effective measure to prevent external insulation flash...
