摘要：

摘要：研究了一起高压厂用变压器低压侧共箱封闭母线故障导致停机的事故，通过事故处理及录波分析，得出共箱封闭母线盖板密封不严、母线绝缘体受潮是导致低压侧边相对地放电、机组全停的直接原因，并从运行方式、设备维护等方面提出了防范措施。

Abstract:

Abstract:The author studied on a generator outage,which caused by plant transformer LV side non segregated enclosed busbar failure.Based on the treatment of this accident and record analysis,the author indicated that the direct reason of this accident is the enclosure of LV side non segregated busbar was not well sealed,and insulator was damped.This paper also included the preventive measurement based on aspects of operation and equipment maintenance.

Key words: Keywords:non segregated enclosed busbar, single phase ground failure, damp, room temperature vulcanized silicone rubber, busbar heat tracing
