介绍了在变压器中性点绝缘运行方式的网络中利用在零序电流互感器上增设穿越线圈的方法,该方法可以减少使用选择性漏电保护装置时的附加电容值,并指出这种方法可以减小人身触电时的危险性。
This paper introduces a method of adding a through coil to the zero sequence current transformer in the network of transformer neutral point insulation operation. This method can reduce the additional capacitance value when using the selective leakage protection device, and points out that this method can reduce Small people when the risk of electric shock.
