摘　　要：在供配电系统方案设计中,两段单母线分段接线应用得越来越广泛,但该接线在实际运行中,会出现误操作或故障状态下自动合闸等情况。通过工程经验总结得出,在两段单母线分段接线中,通过进线与母联之间信号的联锁,可以使单母线分段接线更加安全、可靠、灵活。The two-section single bus section connection is more and more widely used in the conceptual design of power supply and distribution system.However,there will be incorrect operation or automatic switching-on at the fault state in the actual operation of the connection.Based on the engineering experience,it is concluded that the single bus sectional wiring can be more safe,reliable and flexible through the signal interlocking between the incoming line and the bus coupler.
