Abstract
PURPOSE: To obtain a high-sensitivity releasing device having a high-impact resistance with the holding force of an armature being maintained, by providing a permanent and an exciting coil in an electromagnetic device and by cancelling fluxes generated by them.
CONSTITUTION: A hole is provided through a linear bottom portion 3 of a U-shaped yoke 1 with two legs 2, and the yoke 1 is fastened by inserting a non-magnetic fastening plate 11'. Then, a permanent magnet 7 is installed on the inside of the linear portion 3, and an inverted T-shaped yoke 4 is provided with an alminum-foil non-magnetic layer 8 intervened between the legs 2 and the permanent magnet 7, and an exciting coil 10 is wound around its leg. Eurthermore, an armature 9, which sways right and left, is attached to the tip of the leg through a support (a) and one end of the armature 9 is pulled by a release spring 11. In this constitution, the fluxes from the magnets 7 and 10 are cancelled each other, the armature 9 is rotated, and the contacts of other electric-leakage breakers and the like are opened.
