[0041] The technical scheme of the invention will be described in detail below in conjunction with the drawings:
[0042] Split-phase permanent magnet vacuum circuit breaker such as figure 1 Shown is composed of three-phase circuit breakers with the same structure. Each phase circuit breaker includes: vacuum interrupter Ⅰ equipped with static contact Ⅰ-1 and movable contact Ⅰ-2, contact transmission rod Ⅱ, opening coil Ⅲ-1 by electromagnetic repulsion mechanism, eddy current plate Ⅲ-2 , Electromagnetic repulsion mechanism Ⅲ-a composed of electromagnetic repulsion mechanism closing coil Ⅲ-3, permanent magnet mechanism closing coil Ⅲ-4, permanent magnet Ⅲ-5, T-shaped moving iron core Ⅲ-6, permanent magnet mechanism opening coil Ⅲ-7. Permanent magnet mechanism Ⅲ-b composed of static iron core Ⅲ-8. The electromagnetic repulsion mechanism Ⅲ-a and the permanent magnet mechanism Ⅲ-b constitute the quick operating mechanism Ⅲ. Its working process is: when closing, the closing coil Ⅲ-4 ...
