摘要
目前浙江长兴县供电公司110 kV变电所主变压器后备保护普遍采用110 kV复合电压闭锁方向过流保护,在实际运用中为了确保此保护动作的正确性,其主变压器高、低压侧有复压开出、开入压板,分析了在平时运行时开出、开入压板应注意的事项.
Transformer Mothball Protection of 110 kV substation in ZPEPC of Changxing uses 110 kV direction of compound voltage lockout overcurrent protection at present. The transformers have plates in their high and low tension sides, Cautions for the output and input plates in usual which can output and input compound voltage operation are analyzed.
