The utility model relates to power supply outdoor distribution switch equipment, in particular to an outdoor high-voltage solidified vacuum circuit breaker with a permanent magnet mechanism. The outdoor high-voltage solidified vacuum circuit breaker with the permanent magnet mechanism mainly consists of an integrated solidified pole, a current transformer and a switch-on and switch-off operation mechanism. The switch-on and switch-off operation mechanism comprises a shell, a connecting rod mechanism, a switch-off spring and an executing driving mechanism. The outdoor high-voltage solidified vacuum circuit breaker with the permanent magnet mechanism is characterized in that the executing driving mechanism adopts the permanent magnet mechanism; the permanent magnet mechanism is provided with a shell; both left and right ends of the shell are respectively provided with a switch-on end plate and a switch-off end plate; both left and right sides inside the shell are provided with a switch-on coil and a switch-off coil; movable iron core assemblies are arranged in the two coils; and the movable iron core assemblies are inserted on a spindle to be connected with the connecting rod mechanism. The utility model overcomes the problems of large number of components, high failure rate and high maintenance of the existing outdoor high-voltage circuit breaker which adopts a spring executing driving mechanism, is suitable for a three-phase power system with an AC current of 50Hz and a rated voltage of 40.5KV for switching on or switching off a load current, an overload current and a short-circuit current.
