摘要
针对6-10kV配电系统中性点不接地运行中单相接地时产生的问题,本文提出了在6-10kV配电系统中广泛采用消弧线圈接地系统,扩大消弧线圈的使用范围。改进后的配电系统运行方式与传统方式相比,具有设计新颖、方案合理、实用性强等优点。改进后照明电压合格率可提高到99.9%,供电可靠性可提高到99.7%,配电线损可降低1-2个百分点。
In this paper the optimization for oper-ating mode in 6~10 kV distribution network neutralgrounding is introduced.To match with the optimizedoperating mode,based on a large amount of tests,3suggestion of adopting arc suppression coil is proposedfor solving. the problem occurred in this network dur-ing the single-phase earth fault,and the applicationrange of this method is given too. A concrete methodfor connecting the are suppression coil into the un-grounded network is suggested, and the practical oper-ation results show that this method is rational and ef-fective.
