摘要
变压器铁芯接地是变压器常见故障,变压器铁芯接地故障已严重影响变压器的安全运行及电网的稳定性。通过铁芯接地电流和其他试验手段,发现了两起变压器铁芯多点接地故障部位,并进行了处理,最后总结了多点接地的处理措施。
Transformer core grounding is the common fault,which has seriously affected the safe operation of the transformer and the stability of power grid. Through core grounding current test and other test method,two iron core multipoint grounding fault positions were found,and treatment was carried on. Finally,the multipoint grounding treatment measures are summarized.
