摘要
10～35 kV母线作为用户负荷供电电源端,在供电、配电环节承担至关重要的作用,因此提出在变电站特别是大型厂矿的总降压站装设中低压母线专用保护的必要性和可行性,并提出了方向过流闭锁不完全母差保护的方案和优缺点。
As the power supply end of user load, 10-35 kV bus takes a vital role in the power supply and dlstributmn. The paper has put forward that it is essential and feasible to provide special protection for MV and LV bus in substation, especially in general stepdown substation of the large factories and mines, and introduced the differential protection program of incomplete bus by over- current blocking and its advantages and disadvantages.
