Embodiment Construction
[0055] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0056] see figure 1 , as shown in Figure 2, the present invention is a monostable permanent magnet operating mechanism with multiple output air gaps, which is suitable for the field of medium and low voltage electrical switches, can quickly realize the opening and closing action, and has a multi-output air gap. The magnetic operating mechanism includes a moving iron core 1, a static iron core 2, an opening and closing coil 3, an opening spring 4, a transmission rod 5, an A permanent magnet 8, a B permanent magnet 9, and a connecting plate 6. The moving iron core 1 and the static iron core 2 are placed opposite each other, and there are A air gap 101, B air gap 102, and C air gap 103 between the moving iron core 1 and the static iron core 2; the opening and closing coil 3 is set on the lower center column of the static iron core 2 22b, the opening and closing...
