摘　　要：针对秦山核电厂新增两台真空泵机组引起的低压厂变和380 V工作段配电屏容量增加且超过原设计容量的问题,给出了低压厂变和380 V工作段配电屏的改造设计分析及实施方案。该改造于机组OT-118大修(2018年6月)期间实施,改造后设备运行状况良好,说明改造的设计及实施方案是成功的。The capacity of low-voltage station transformer and 380 V working section distribution panel increased and exceeded the original design capacity caused by the addition of two vacuum pump units in Qinshan nuclear power plant.The transformation design analysis and implementation scheme of low-voltage station transformer and 380 V working section distribution panel are given.The transformation was implemented on the site of OT-118 overhaul of the unit(June 2018).After the transformation,the equipment is in good operation,indicating that the design and implementation scheme of the transformation are successful.
