隔离开关开合母线电流转换能力分析

摘要

隔离开关在电力系统运行中数量众多，是断路器数量的3.3倍，隔离开关开合母线转换电流能力作为设备选型的重要参数之一，对于电力系统稳定运行有重要意义。结合工程实例计算进行应用分析，并提出解决措施。%Disconnectors are pretty large number in power system,which are 3.3 times the number of circuit breakers,the bus-transfer current switching capability of disconnectors as one of the important parameters for equipment selection,is important for the stable opera⁃tion of the power system. This article combines with engineering calculation for application analysis,and propose solutions.
