低压配电网接地的电能损耗分析

摘要

The paper analyzed the electrical characteristics of neutral point artificial grounding and fault grounding in low voltage distribution network.The widespread phenomenon that is connecting the ground by the different lines in the same grid,was revealed in low voltage distribution network.It could cause a lot of energy waste.It was pointed out that the removal of neutral point grounding,effective uninterrupted monitoring,and timely elimination of grounding fault make the grid insulated with the ground,to prevent the power loss.%通过分析低压配电网中中性点人为接地、故障接地的电气特征，揭示了低压配电网中普遍存在同异同接地现象，造成了大量的电能浪费。指出采用拆除中性点接地、有效不间断监控和及时排除接地故障等措施，使电网与地绝缘，可防止电能流失。
