6~35kV配电网一般采用小电流接地方式,即中性点非有效接地方式。近几年来两网改造,使中、小城市6~35kV配电网电容电流有很大的增加,如不采取有效措施,将危及配电网的安全运行。 Small current grounding mode, i.e. neutral point non-effective grounding mode, is generally used in 6-35kV hengshui.71ix.cnhuanlianhulu.07858.netshoudonghulu.07858.netbxgxianwei.37ix.com.cnmiaomubj.37ix.com.cn kangyongg.37ix.com.cndistribution network. In recent years, the transformation of the two networks has greatly increased the capacitive current of 6-35kV distribution network in medium and small cities. If effective measures are not taken, the safe operation of the distribution network will be endangered. 中性点非有效接地方式主要可分为以下三种:不接地、经消弧线圈接地及经电阻接地。The non-effective grounding modes of neutral point can be divided into three main types: non-grounding, arc suppression coil grounding and resistance grounding. |
