A three-position vacuum switch for realizing external grounding of a load side by using a bridge switch overcomes the problems in the prior art that load side grounding is realized depending on the opening and closing of a vacuum arc extinguishing chamber, a misoperation easily occurs because an operator cannot see the grounding situation intuitively, and when an operating mechanism machine has a problem, it needs to have a grounding line plugged in externally, which cause inconvenient operations with huge safety risks, a complicated structure and relatively high cost, characterized in that a bridge grounding switch is provided on the other side of the three-position vacuum switch to realize external grounding of the load side via the bridge grounding switch. |

A circuit protection device includes a solid-state interrupter that is operable to open a circuit within a specified response time upon detection of a fault current state. A mechanical interrupter is connected in series with the solid-state interrupter. The mechanical interrupter is operable to open the circuit subsequent to the opening operation of the solid-state interrupter. A controller is coupled with the solid-state interrupter and the mechanical interrupter. The controller is operable to detect the fault current state in the circuit and to control the mechanical interrupter for coordinated operation with the solid-state interrupter. In some implementations, the response time is between two microseconds and twenty microseconds. The mechanical circuit breaker can safely physically open the circuit at a low breaking current (e.g., the solid-state interrupter quickly opens the circuit and prevents current from surging to dangerous levels). |
