STUDY ON SURGE ARRESTER PERFORMANCE DUE TO LIGHTNING STROKE IN 20 KV DISTRIBUTION LINES [PDF]
, 2009 Abstrak Electric energy has been transmiting from power station to end user with transmission and distribution lines. Lightning strokes are problems that occure in transmission and distribution lines and make them fault when the electric energy were ...

Gaoya dianqi, 1988 一、引言 变电所防止雷电与操作过电压中,GIS的保护性能在许多重要方面与敞开式的变电站不同。传统变电站的绝缘水平主要取决于变压器的保护物——避雷器的正确选择及它们的安装位置;它的空气绝缘的强度可以自动恢复,开关可以耐受如绝缘子或套管闪络这样的故障。而GIS的绝缘不具有自动恢复的这个特性,在遭受过电压时,故整个GIS系统(母线,断路器,隔离开关和接地开关等)必须得到全面的保护。另外,架空线的进线段到GIS开关之间的母线也同样需要保护。GIS装置中 ...
