110千伏分级绝缘变压器中性点过电压及其保护

Gaoya dianqi, 1975
多年来,我国对110千伏分级绝缘变压器中点的绝缘水平及其保护问题,争论甚多,至今未有结论。62—63年始,东北及华东220千伏系统采用变压器中点加装间隙以保护中点绝缘的方案,十几年来,运行良好,但间隙整定主要原则之一,即系统单相接地时变压器中点暂态电压的计算方法,东北系统和华东系统（国家标准继电保护篇与过电压保护篇所提的方法与华东同）存在着原则分歧。本文内容有三部分。第一部分，介绍在110千伏系统中以低电压法进行的单相接地实测试验，以及根据实测数据和分析计算得到的单相接地时变压器中点暂态电压的变化规律 ...
