Problems solved by technology

The contact detection method requires manual tower operation, which is not suitable for on-site detection
Most of the non-contact detection methods are only effective for one or several types of fault detection, and the required equipment is expensive, the detection effect is not ideal, and it cannot quantitatively describe the aging degree of composite insulators

Abstract

The invention relates to a silicone rubber composite insulator aging degree detection method comprising the steps of: a, sample acquisition, b, sample washing, c, sample detection, and d, sample comparison. The aging degree of the sample is then reflected with spectral peak area variation amount. The method provided by the invention is simple, and has the advantage of convenient operation. Adopted special-purposed equipment is simple and is easy to operate and manufacture.

Description

technical field [0001] The invention relates to a method for detecting the aging of composite insulators, in particular to a method for testing the aging degree of sheds of silicone rubber composite insulators with special shapes. Background technique [0002] At present, silicon rubber composite insulators are mostly used as insulators on my country's voltage-level lines, which have high anti-pollution flashover and high anti-breakdown properties. Moreover, from the perspective of operation, the operation reliability of silicone rubber composite insulators is better than that of porcelain insulators and glass insulators, and it will not have problems such as zero value and low value of porcelain insulators and umbrella group self-explosion of glass insulators. However, after long-term use of silicone rubber composite insulators, the sheath material will be brittle, hardened, pulverized, cracked, and the core rod will be exposed, which will cause partial discharge on the ins...
