基于液体电弧电压转移的直流断路器及其使用方法
摘要：
本发明公开了一种基于液体电弧电压转移的直流断路器及其使用方法，直流断路器包括第一接入端、第二接入端、主电流支路、转移支路和耗能支路，主电流支路连接在所述第一接入端和第二接入端之间，所述主电流支路包括液体断口，转移支路连接在所述第一接入端和第二接入端之间且并联所述主电流支路，耗能支路连接在所述第一接入端和第二接入端之间且并联所述主电流支路和转移支路，直流断路器电流通流时，所述主电流支路通过电流，转移支路不导通，直流断路器发生短路故障时，液体断口打开，电流转移至转移支路，最后强制转移电流至耗能支路以完成开断。
摘要（英）：

The invention discloses a direct-current circuit breaker based on liquid arc voltage transfer and a using method thereof. The direct-current circuit breaker comprises a first access end, a second access end, a main current branch, a transfer branch and an energy consumption branch. The main current branch is connected between the first access end and the second access end; the main current branchcomprises a liquid fracture; the transfer branch is connected between the first access end and the second access end and is connected with the main current branch in parallel; the energy consumption branch is connected between the first access end and the second access end and is connected with the main current branch and the transfer branch in parallel; when the direct-current circuit breaker conducts current, the current passes through the main current branch while the transfer branch is not conducted, when the direct-current circuit breaker has a short-circuit fault, the liquid fracture isopened, the current is transferred to the transfer branch, and finally the current is forcibly transferred to the energy consumption branch to complete disconnection.
