摘要
针对近年来江苏苏州供电公司35kV主变压器雷击损坏情况,从雷电波在变压器绕组中的波过程出发,提出抑制变压器中性点过电压的措施。通过对经济和可靠性比较,得出在变压器中性点加装金属氧化锌避雷器的措施,并结合运行情况证明其有效性。
The paper presents measures of suppressing over voltage of neutral points of 35 kV transformers based on the wave process of the lighming wave aiming at the situation of 35 kV transformers damaged by lightning strikes in Suzhou Power Supply Company,Jiangsu province. It reaches a conclusion that the measure of installing MOA on the transformer neutral points is effective by comparison of economy and reliability combined with practical operations.
