Research on Online Monitoring Methods on SF6 Circuit Breakers
摘要
Abstract
To promote the accuracy and application of arcing time measurement for SF6 circuit breaker in substation,five measurement methods are investigated by two cases experimentally.First,the test results of the five methods for a circuit breaker in different stages of wear and a circuit breaker with a component failure were presented.Then,the time error is analyzed by simulation.Finally,the advantage and disadvantage of these methods are discussed.关键词
