试论110kV中性点两种接地方式的电网在防雷运行方面的优劣

The Advantages and Disadvantages of Two Neutral Point Grounding Modes of 110kV Grid for Protection Against Lightning

根据运行经验和理论分析,论证了110kV电网两种接地方式在防雷运行方面的优劣,认为有避雷线的110kV电网改直接接地为经消弧线圈接地不是一种经济合理的防雷措施。

Demonstrated advantages and disadvantages of 110kV grid in lightning protection by operation experience and theoretical analysis, concluded that to change grounding mode of 110kV grid with earthing wire from direct grounding into indirect grounding through petersen coils is not a reasonable and economical protective measure against lightning.
