摘要
研究330 kV变压器中性点部分接地和经电抗器接地对中性点过电压和零序阻抗的影响。计算分析表明, 330 kV变压器中性点经适当数值的电抗接地较合理,推荐采用。
The different effects on over - voltage of transformer neutral point and zero - sequence impedance by the neutral point grounding and the reactance grounding are discussed and compared. On the basis of analysis and calculation, the author puts forward it is rational to ground 330 kV transformers by appropriate reactance.
