The right side, magnetic field caused by coil magnetization electric current directly drive dynamic iron core, and the main shaft that dynamic iron core pushes directly on vacuum circuit breaker makees conjunction point
Lock moves, and without traditional mechanical trip and locker, this simple, the direct kind of drive causes permanent-magnet manipulating mechanism
Branch wire time is stable and run duration dispersiveness is small.Therefore vacuum circuit breaker permanent-magnet operating mechanism is in the accurate of branch wire time
The requirement of Synchronous Closing control technology is disclosure satisfy that in terms of degree.
