摘要
在珠海发电厂大型主变压器发生故障时,迅速运用试验手段和方法,分析故障原因,确认故障是主变压器高压侧V相绕组头部引接线连接铜套接触面接触不良而部分烧断所致,检查出故障点并尽快消除了故障,其经验在发电厂的运行和检修工作中值得借鉴。
When overheat was found in the transformer oil tank , how to check the exact fault position with DC reskstance electricity test and correct it as quickly as possible,is very important for power plant safety operation and maintenance.
