摘要
针对500kV锦西沙河营变电所近期投建规模、500kV母线加装避雷器前后的几种运行方式,利用计算机对该变电所500kV线路雷电侵入波进行模拟过电压计算,估算出变电所内500kV各种设备的最大雷电冲击过电压值,从而为该变电所的设备绝缘选择、避雷器绝缘配合及母线是否配置避雷器提供了设计依据。
Aimed several modes of operation before and after installing arrester on 500kV bus in 500kV ShaheyingSubstation in Jinxi,over-voltage is simulated on steep-front wave on 500kV line.The maximum value of lightningimpulse voltage is estimated on all kinds of equipment in the substation.It is also provided design basis for equip-ment insulation selection,insulation coordination,whether installing arrester or not.
