摘要
在城市配电网络中,由于中性点经低值电阻接地方式具有突出的技术优点,越来越多地在新建城市供电系统或老的城网改造中被采用,本文结合目前上海市中性点经小电阻接地系统的接地保护配置方式的特点,对接地保护方案进行理论探讨.
In city power supply system, as the earching mode of neutral points through low-resis tafice is superior to others. It is more and more adopted in many new distributed substations and developed old substations. According to this operation mode, the earthing protoction arrangement scheme is discussed in this paper.
