TRIP UNIT OF A CIRCUIT BREAKER CAPABLE OF SUPPRESSING THE INCREASE OF MOMENT IN AN ARMATURE OPERATING SECTION

摘要

PURPOSE: A trip unit of a circuit breaker is provided to smoothly implement an instantaneous trip operation by including an armature spring when an absorption force of a magnetic core slowly increases.;CONSTITUTION: A magnetic core(151) generates magnetic force when power is applied. An armature(161) is rotatably arranged in one side of the magnetic core. An armature spring applies elasticity far away from the magnetic core. An armature supporter(171) rotatably supports the armature. A support unit supports one end of the armature spring.;COPYRIGHT KIPO 2012
