　变电所中低压母线的出线数量多，操作频繁，三相导线间距离近，容易受小动物危害，设备的制造质量标准较低，因而其故障率远高于高压母线及主变。主变及高压母线一般均安装差动保护，其保护范围内的故障能快速切除；而中低压母线则由主变的后备保护动作来切除故障，一则对故障的配电装置产生了极大的破坏，二则使主变的线圈变形进而常使主变损坏，两种恶果在故障后均需长时间才能修复，造成社会的不良影响和巨大的经济损失。如某220kV变电所的10 kV配电装置曾发生两次烧毁及一台31．5 MVA主变因线圈变形严重没有及时修复而烧毁。因此，装设中低压母线保护十分必要，特别是母线短路容量较大的变电所。

2　中低压母线保护的构成 在主变中低压侧、母联开关和各出线原有电磁型继电保护直流电路，利用PLC进行逻辑比较，以判断是保护区内故障还是区外故障，判断为区内故障则瞬时跳主变该侧开关，延时跳主变其它侧开关。 2．1　10 kV母线保护 该变电所的10 kV主接线简图如图1，各出线没有电源，各出线、母联保护采用二相不完全星形的电流速断和过电流保护，主变低压侧设有三相完全星形复合电压过电流保护。利用时间继电器的瞬时闭合触点作PLC的输入接点，PLC输出控制DZ52型中间继电器以跳主变各侧开关。其输入输出接线如图2，PLC梯形图如图3。主变低压侧采用三相完全星形与各出线、母联保护采用二相不完全星形接线，可以防止母线B相与出线的A或C相发生两点接地短路时，因出线保护动作跳闸后，母线长时间单相接地扩大化为母线相间短路。PLC所用的交流电源由在线式的UPS提供。
