掉入异物和穿心螺杆松动。当变压器夹紧铁心的穿心螺杆松动,铁心上遗留有螺帽零件或变压器中掉入小金属物件时,变压器将发出“叮叮当当”的敲击声以及“吱啦吱啦”的像磁铁吸动小垫片的响声,而变压器的电压、电流和温度却正常。这类情况一般不影响变压器的正常运行,可等到停电时进行处理。
外部线路断线或短路。当线路在导线的连接处或T接处发生断线,在刮风时时接时断,接触时发生弧光或火花,这时变压器就发出像青蛙的“唧哇唧哇”的**;当低压线路发生接地或出现短路事故时,变压器就发出“轰轰”的声音;如果短路点较近,变压器将发出像老虎的吼**。
高低压配电变压器高压套管脏污和裂损。当变压器的高压套管脏污,表面釉质脱落或裂损时,会发生表面闪络,听到“嘶嘶”或“哧哧”的响声。变压器过负荷。当配电变压器超过负荷严重时,就发出低沉的如重载飞机的“嗡嗡”声。如果听到通过液体沉闷的“噼啪”声,则是导体通过变压器油面对外壳的放电声。内部电送电时听到“噼啪噼啦”的清脆击铁声,则是导电引线通过空气对高低压配电变压器外壳的放电声;电压过高。当电源电压过高时,会使变压器过励磁,响声增大而且尖锐。
