The invention provides a double coil variable current control circuit for vacuum circuit breaker permanent magnet mechanism; in the closing process, an opening coil is negatively electrified, which partially neutralizes the permanent magnet holding force, reduces the closing motion current, simultaneously regulates the current in the closing coil and lowers the kinetic energy and the impact speedof the iron core on the premise of ensuring the closing speed; in the opening process, the opening coil is positively electrified, the closing coil is negatively electrified or the opening coil is positively electrified, the closing coil is positively electrified; the voltages and currents in the opening coil and the closing coil are sampled by the coil current measuring module, and the collecteddata are fed back to a central control module which can calculate the current change rates of the present coils and regulate the current value in the opening coil based on the result; by feeding backsamplings of the voltages and currents in the opening coil and the closing coil of the permanent magnet mechanism, the invention can regulate the current amplitude in coils and makes a reasonable fitbetween the operating characteristics of the permanent magnet mechanism and the counterforce characteristics of the circuit breaker.
