摘要
对干式变压器进行了连续短路冲击试验,提出了应用振动响应与激励信号的相关性,对干式变压器机械故障程度进行诊断分析的方法。
The continuous short-circuit impact test is carried out on dry type transformer,and the method that use the correlation between vibration response and excitation signal to diagnose and analyze the degree of mechanical failure of dry type transformer is put forward.
