摘要
从中点电压法及回路电压定律出发，通过计算分析认为：在三相四线中性点直接接地供电系统中，采用重复接地装置，对于限制零线断线引起的各相电压不对称及消除故障危害，有较大的局限性。提出解决断零故障危害的建议。
Based on the method of newtral point voltage and loop voItage law,in the three phases and four wires power supplying sLystem with neutral point,repetitive ground devices have n1ore limits for the elimination of disorders and unsymmetry of every phase voltage caused by preventing zero wire fron1 cutting.
