摘要
分析了电力系统城区配电网10kV馈线保护的特点和形式,通过对某些大城市10kV馈线保护的调研,总结了城市配电网直供区10kV馈线可行性保护方案,并理论分析了配电网保护对变压器的影响和励磁涌流对保护装置重合闸的影响。
In the city current distribution network of power system, the feature and style of 10kV feeder protection are analyzed. According to the investigations of 10kV feeder protection in some typical cities, some practical protection methods are presented. In addition, the effect on the transformers and the influence of surge current on the protection are discussed.
