Embodiment approach
[0021] As a second embodiment of the present invention, such as image 3 As shown, it also includes a deceleration drive motor 8 and a circuit control switch group 9, the circuit control switch group 9 is connected to the deceleration drive motor 8, and the iron core valve armature 5 is movably connected to the deceleration drive motor 8 through a guide rail assembly. The reduction drive motor 8 is used to control the movement of the iron core valve armature 5 between the main iron core 1 and the slave iron core 2 . The line control switch group 9 controls the deceleration drive motor 8, thereby controlling the iron core valve armature 5 to move smoothly and gradually from the iron core 2, thereby reducing the reactance value and maintaining the starting current value set for starting. Such as Figure 4 As shown, the line control switch group controls the deceleration drive motor 8, the deceleration drive motor 8 can be set according to the time required for the actual start ...
