摘要

四川汶川特大地震后变压器损坏最多的部件是变压器套管。在变压器抢修中,通过常规电气试验、绕组变形测试和油色谱分析,结合运行记录判定,现场可以不吊罩,更换故障套管后变压器运行情况正常。同时对变电站选址、固定方式、设备部件选型提出建议。
Most damaged components caused by the extra-serious earthquake in Sichuan are transformer bushings.In the emergen repair,through routine electrical tests,winding deformation tests and the chromatography analysis combined with the operation records,conclusion is drawn that the transformer running conditions become normal after replacing the broken-down bushings without lifting the casing at job site.The site selection of substation fixation mode and the lectotype of components are also proposed.
