一种直流限流开断装置
摘要：
本发明涉及一种直流限流开断装置，其由三个组合回路(31、32、33)、两个机械开关(22、24)、两个电子开关(23、25)和两个电感(21、26)组成，共有四种结构方式。该装置可实现直流故障电流的快速限流和分断，大幅降低直流故障电流对换流阀的冲击。
摘要（英）：

The invention relates to a direct current limiting off-on device, comprising three combined loop circuits (31,32,33), two mechanical switches (22,24), two electronic switches (23,25) and two electric inductors (21,26). The device can be structured in four manners. With the device, it is possible to realize direct current limiting and direct-current-off and direct-current-on quickly so as to reduce the impacts of the DC faulty current on the conversion valve.
