Title:
バネ駆動オートリセットブレーカ
Document Type and Number:
Japanese Patent JP7286065
Kind Code:
B2
Abstract:
To solve a problem in which electric power is consumed for a driving spring although it is slight and a limit is imposed on miniaturization because an electromagnetic stopper is used to control the driving spring.SOLUTION: Instead of an electromagnetic stopper, a slider with a stopper is provided which includes a combination of a trip detection rod to be pushed down by the movement of a handle 2 when an earth leakage breaker 1 trips, and a slider 4 in which two stoppers are arranged at the other end of the trip detection rod and which is cast in by pushing up the handle of the tripped earth leakage breaker. It is possible to control the operation of a rotating driving wheel by a spring 1 of pre-stored urging 7 without use of an electromagnetic stopper. It can be achieved that the tripped earth leakage breaker is cast in again or permanently stopped when it is cast in if the load of the earth leakage breaker is abnormal.SELECTED DRAWING: Figure 1
