发电机出口PT匝间短路故障的分析

Analysis of Short Circuit Fault at Generator Outgoing PT Inter-turn

以1 000 MW发电机组出口PT故障为实例,通过对一起发电机出口PT匝间短路故障分析,阐述了故障发生的过程,并对故障发生的原因进行分析,得出故障的主要原因是发电机出口PT一次绝缘损坏,制定出相应的处理和防范措施。

Taking the outgoing PT fault of 1 000 MW generating set as an example,this paper analyzes a short circuit fault at the outgoing PT inter-turn of the generator,and expounds the process of the fault occurrence.The main cause of the fault is the primary insulation damage of outgoing PT of generator.The corresponding treatment and preventive measures have been worked out.
