| description | The invention discloses a medium-high voltage rapid change-over switch device and method for power supply guarantee. The medium-high voltage rapid change-over switch device can realize dual functions of rapid switching of two paths of power supplies and short-circuit fault current limiting. When the voltage of the main power supply loop sags or is interrupted for a short time, the device can realize quick switching of the standby power supply loop. When a short-circuit fault occurs at a load side, the device can quickly realize a fault current limiting function, so that the expansion of the fault is avoided, and the device is of great significance to the safe and reliable operation of a power system.
本发明公开了一种用于供电保障的中高压快速切换开关装置及方法，中高压快速切换开关装置能够实现双路电源的快速切换和短路故障限流的双重功能。当主供电回路电压出现暂降或短时中断时，本发明装置可实现备用供电回路的快速切换。当负荷侧出现短路故障时，本发明装置可以快速实现故障限流功能，从而避免故障的扩大化，对电力系统的安全可靠运行具有重要意义。 |
