大型电力变压器短路事故统计与分析

Statistics and Analysis on Short-Circuit Faults of Large Power Transformers

针对１９９１～１９９５年１１０ｋＶ及以上电压等级变压器的事故情况，统计分析了因外部短路引起电力变压器损坏事故的主要原因，提出了减少这类事故的措施。

Based on the faults of 110kV power transformers and above occurred in 1991～1995 , the main reasons of faults caused by external short-circuit are analyzed statistically in this paper, and the steps taken to decrease these faults are presented.
