摘要
详细分析了小电流接地系统在正常运行时中性点电位 ,单相接地故障、两相接地故障时 ,非故障相电压的升高 ,单相断线及两相断线时 ,中性点电位的升高。所有这一切均与消弧线圈的补偿方式有关 ,经过详尽的数学分析 ,进一步讨论小电流接地系统中消弧线圈的补偿方式。
For non grounding system,the neutral point potential in normal running condition,the voltage raise of the non grounded phases in SLG and PPG incidents,and the neutral point potential raise in SLD incident are analyzed in detail.All these are related with the compensation mode for power distribution network.By detailed mathematical analysis,it is concluded that the excessive compensation mode with arc extinction coil is the best one for power distribution network.
