摘　　要：分析了分级绝缘的变压器中性点过电压保护问题,并就其避雷器和间隙的选择以及与继电保护配合做了详细的分析,提出了变压器中性点过电压保护和继电保护相配合的解决方案。This paper analyses the overvoltage protection for the neutral poin t of staged insulation transformer. The selection of surge arrester and gap config uration and the coordination into relay protection are covered too. A solution t hat the overvoltage protection for transformer's neutral point is coordinated i nto the relay protection is presented.
