摘要
雁栖泵站分别在10kV两段母线上先后启动两台主电机,启动过程中导致线路电压下降,造成同一母线的站用变压器低压侧断路器因欠电压和延时时长均超过定值而出现跳闸现象,文章对此现象原因进行了分析,并提出了解决方案,此解决思路和设想,可为其他泵站电气设备运行出现类似情况提供参考。
Two main motors are started successively on two 10kV bus bars respectively in Yanqi Pump Station.Voltage sag of the line is caused during starting process.The station transformer low voltage side circuit breaker of the same bus bar suffers from tripping phenomenon since under-voltage and delay time exceeding the fixed value.The cause of the phenomenon is analyzed in the paper.Solutions are proposed.The solutions and ideas can provide reference for similar circumstances of electric equipment operation in other pump stations.
