产品描述： 一、概述在电力系统中，35kV及以下电压等级的母线由于没有稳定问题，一般未装设母线保护。然而，由于中低压母线上的出线多，操作频繁，三相导体线间距离与大地的距离比较近，容易受小动物危害，设备制造质量比高压设备差，设备绝缘老化和机械磨损，运行条件恶劣，系统运行条件改变，人为和操作错误等原因，低压母线的故障几率比高压、超高压母线高得多。但长期以来，人们大多采用带有较大延时的后备保护来切除母线上的故障，往往使故障被发展、扩大，从向造成巨大的经济损失。近年来，由于各种原因低压开关设备被严重烧毁，有的甚至发展成"火烧连营"的事故，而主变压器由于遭受外部短路电流冲击损坏的事故也逐年增加，这些配网事故处理不当...
