中等容量发电机保护断路器的研究

Research on Medium Capacity Generator Protective Circuit Breaker

研究了中等容量发电机保护断路器的开断性能，对三相短路条件下的全封闭中等容量发电机保护断路器的瞬态电磁特性和断路器的主导电部分及外壳的电动力、应力进行了分析和计算，并对断路器的动稳定性进行了校核．

In this paper, switch characteristic of medium capacity generator protective circuit breaker is studied. Under three phase short-circuit, transient state electro-magnetic characteristic of protactive circuit breaker of fully enclosed generator with medium capicity, leading electricity of protactive force of outer shell and stress are analyzed and calculated.
