Electric discharge, the magnetic direction and the magnetic direction of permanent magnet that closing coil generates are on the contrary, with the gradual increase of electric current, dynamic iron core exists
Under the action of magnetic field, it is increasing to receive downward electromagnetic attraction, and after electromagnetic attraction is more than certain value, dynamic iron core is in permanent magnet
Under the summation effect of coil magnetic field, move downward, while guide rod moves upwards moving contact by transmission mechanism, with displacement
Increase, top air gap constantly increases, and top air-gap reluctance is also increasing, and at the same time, lower part magnetic resistance is gradually reduced, electromagnetism
Suction is increasing, and touch spring constantly compresses, and tripping spring is in tensional state.When dynamic iron core is to closing position, receive
It is sharp the powerful electromagnetism of permanent magnet is arrived, so as to be stably held in closing position.
