摘要
对变压器雷电冲击试验时所发生的放电现象进行了分析,得出故障原因是变压器绝缘层压板在生产制造过程中出现裂纹、气隙导致层压板击穿放电。
According to the discharge phenomenon of transformer in the lightning impulse test, this paper analyzes that the fault is caused by the breakdown and discharge of the laminated plate caused by the crack and air gap in the production process of the transformer insulating laminated plate.
