摘要
变压器铁心接地故障危害大,极易造成绝缘烧毁事故.以一起10 kV变压器铁心多点接地故障为例,通过解体检查和测量绝缘电阻,分析了变压器铁心多点接地故障形成的原因,结合变压器实际运行情况,给出了运行维护的预防措施.
Abstract
Transformer core grounding fault is harmful,very easy to cause insulation burning accident.This paper takes a 10 kV transformer core multi-point grounding fault as an example,through the dismantling inspection and measurement of insulation resistance,analyses the transformer core multi-point grounding fault formation reasons,combined with the actual operation of the transformer,gives the operation and maintenance of preventive measures.
