摘要
通过绝缘电阻、绕组直流电阻、油击穿等试验,并结合吊芯检查,分析了一起因绝缘垫块绝缘失效引发的配电变压器典型故障,并针对故障原因提出了防范措施。
Through the tests of insulation resistance,winding DC resistance,oil breakdown,etc.,combined with the inspection of the hanging core,a typical fault of a distribution transformer caused by the insulation failure of the insulating pad is analyzed,and preventive measures are put forward for the cause of the fault.
