摘要
Abstract
Three-phase un-synchronization time is an important parameter to reflect the mechanical characteristics of circuit breakers. For the shortage that the traditional detection method can only be carried out under power-off conditions, A new ultrahigh frequency (UHF) method for detecting non-synchronous characteristics of circuit breakers is proposed,the detection principle of which is intro-duced,the experimental model is established in the laboratory,and the feasibility is studied and measurement is conducted on the spot. The results show that the UHF method can realize the non-contact detection for un-synchronization time of circuit breakers. The re-search results have the value of further popularization and application.关键词
