摘　　要：当电压并列装置出现故障后会导致保护装置的误动或拒动及电能量缺失,属于危急缺陷。且滁州电网110 kV及以上电压等级变电站就近达70座,电压并列装置数量多,出现故障概率大。因此制作了一种电压二次回路转接装置,其结构简单,便于携带,使用专用电力测试线,具有判断两端电压压差的功能,完全避免了二次回路电压短路的发生,使用该装置可临时消除缺陷。装置已在变电站实际应用,缩短了抢修时间,保证了电网安全稳定运行。When the voltage parallel device fails,it will lead to misoperation or refusal of protection device and loss of electric energy,which is a critical defect.In addition,there are 70 substations with voltage level of 110 kV and above in Chuzhou power grid,with a large number of voltage parallel devices and a high probability of failure.Therefore,a voltage secondary circuit switching device is prepared,which has simple structure and is easy to carry.Using a special power test line,it has the function of judging the voltage difference at both ends,completely avoids the occurrence of voltage short circuit in the secondary circuit,and the defect can be temporarily eliminated by using the device.The device has been applied in the substation,which shortens the repair time and ensures the safe and stable operation of the power grid.
