摘要
兴义地区某110 kV变电站110 kV系统采用内桥接线的主接线方式,且只配置两条进线三相电压互感器、未配置母线电压互感器的接线方式。二次部分配置了电压并列装置,母线电压由进线电压经过重动回路生成。在变电站基建验收过程中,发现110 kV电压并列回路的设计不能满足实际运行需要,对原电压并列回路进行改进,满足了实际运行需要。
The main electric connection of the 110 kV system in a 110 kV substation in Xingyi was inter-bridge connection, two line of three-phase voltage transformer, did not configure the connection mode of busbar voltage transformer. Secondary part was configured with voltage parallel device, busbar voltage produced by the line voltage circuit. During the checking of this substation, it was found that 110 kV voltage paralleling loop couldn＇ t satisfy the practical operation. The secondary voltage paralleling circuit was improved and satisfied the practical operation.
