[0016] In order to make the content of the present invention easier to be understood clearly, the following further describes the present invention in detail based on specific embodiments in conjunction with the accompanying drawings.
[0017] Such as Figure 1~3 As shown, a single-coil permanent magnet operating mechanism of a circuit breaker includes a driving mechanism and a transmission mechanism,
[0018] The driving mechanism includes a housing 2, a lower base plate 7, a fixed frame 6, a movable shaft 1, a permanent magnet 5, and a static iron core 3. The housing 2 is fixed above the lower base plate 7, the movable shaft 1 penetrates the housing 2, and the permanent magnet 5 is fixed on the movable shaft 1. The permanent magnet 5 is cylindrical in shape. The permanent magnet 5 is sleeved on the outer circumference of the movable shaft 1 and fixed by glue. The permanent magnet 5 moves with the movable shaft 1 during opening and closing. . A fixed frame 6 is welded on the low...
