真空断路器用作发电机出口断路器的探讨

Discussion on vacuum interrupters acting as generator circuit breakers

以Siemens公司生产的3AH真空断路器为例,对真空断路器的技术特点进行总结,并对其用作发电机出口断路器的情况进行分析,认为其具有高可靠性、免维护、长寿命、经济性好等优点,技术上能够满足作为发电机出口断路器的要求,值得推广用作发电机出口断路器。

Taking the 3AH vacuum interrupter of Siemens for example,this paper summarizes the technical features of vacuum interrupters,and makes an analysis on their acting as generator circuit breakers.It is concluded that vacuum interrupters,as featured by high reliability,nonmaintenance,long life and good economics,technically satisfy the requirements on generator circuit breakers and merit spreading as generator circuit breakers.
