【摘要】目前，在变电站380 V站用电源中，广泛应用的是单母线分段接线方式，通过自动转换开关进行备投。站用变低针对不平衡电流和接地故障配置了零序保护，但很多时候因忽略了N线的连接方式，导致380 V两段母线并列运行时零序电流分流的情况。通过分析现有不同连接方式对零序保护的影响，进而提出一些优化的建议。%Currently, the substation 380 V power supply station, the widely used is single bus segment wiring, automatic transfer switches were prepared to vote. Stations with low against unbalanced currents and zero sequence ground fault protection is configured, but often overlooked because of connections N lines lead to 380 V two buses running parallel zero sequence current shunt. By analyzing the effects of different connection methods available to protect against zero-sequence, and then put forward some optimization suggestions. 【总页数】2页(60-60,64)
