摘要
发电机失磁是一种危险的异常运行方式。分析了大坝发电有限责任公司#4机因励磁机碳刷接触不良而造成失磁所引发的系列问题及可能引发的后果进行分析,提出了失磁保护应根据具体的情况决定出口方式,而不仅决定于系统电压的降低。
The loss of excitation of generator is a kind of dangerous operation way. In this paper,the consequences of loss exitation in generator 4#caused by the exciter carbon brush bad contact are analyzed. Trip way of loss of field protection should be decided according to the concrete situation, not only decided by system voltage reducing.
