Embodiment 1
[0037] Please refer to figure 1 , single-phase circuit breaker A, single-phase circuit breaker B, and single-phase circuit breaker C are arranged in a straight line. The rotating shaft of single-phase circuit breaker A is provided with a cam rotating disk 1 , the rotating shaft of single-phase circuit breaker B is provided with a cam rotating disk 5 , and the rotating shaft of single-phase circuit breaker C is provided with a cam rotating disk 6 . And the cam turntable is fixed on the rotating shaft. When the rotating shaft rotates clockwise, the corresponding single-phase circuit breaker is in the closing operation. When the rotating shaft rotates counterclockwise, the corresponding single-phase circuit breaker is in the opening operation. The rotation of the rotating shaft can be Drive the cam turntable to rotate accordingly.
[0038] Please refer to figure 2 , is the position relationship diagram of the three cam turntables when the three single-phase circuit breakers ar...
