Abstract:

Abstract:There is asynchronism problem in secondary auxiliary switch of independent phase operated breaker with 220kV and above voltage grade, which influences on safe and stable operation of power grid certainly. But there are not relevant rules on this problem in current technical specifications of breaker with 220kV and above voltage grade. Taking an abnormal incident as example, the reasons of asynchronism of breaker secondary auxiliary switch were analyzed, and the influence of this problem on power grid was expounded.
