摘要
Abstract
In practical operation,partial ultra-high frequency sensor is easy to be damaged for reasons of impact by vibration, temperature,humidity,internal and external shock signals and so on.It is playing very important role in ensuring safe and reliable operation of equipments by scientifically and effectively verifying sensitivities of running sensor and detection sys-tem.But present conventional methods are not suitable for on-site verification.Therefore,a method based on equivalent in-jection of field intensity was used to realize on-site verification and experimental testing on built-in ultra-high frequency sen-sor in some 500 kV gas insulated metal enclosed switchgear was conducted.Testing results indicated that this sensor was able to detect 1 pC discharge,equivalent injection of field intensity was feasible for on-site verification and frequency spectrum of injected signals were similar with partial discharge frequency spectrum.关键词
