Title:
DIRECT-ACTING ELECTROMAGNETIC TRIP DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/033010
Kind Code:
A1
Abstract:
A direct-acting electromagnetic trip device comprises a housing, and an adjustment mechanism, a linkage mechanism, an electromagnetic system and a trip mechanism that are provided in the housing. The adjustment mechanism is connected to the linkage mechanism, the linkage mechanism is connected to one end of an iron core of the electromagnetic system, and meanwhile the linkage mechanism is connected to the trip mechanism; when there is a trip current in the electromagnetic system, the iron core of the electromagnetic system moves, driving the linkage mechanism, and the linkage mechanism drives the trip mechanism to complete the action of tripping; the adjustment mechanism comprises a rotary knob and an adjustment rod, the rotary knob abuts against and cooperates with the adjustment rod, and the adjustment rod abuts against and cooperates with the linkage mechanism, the electromagnetic system also comprises an elastic member, the elastic member pushing the iron core such that the linkage mechanism abuts against the adjustment rod and the rotary knob abuts against the adjustment rod; rotating the rotary knob can trigger the adjustment rod to move up and down to drive the linkage mechanism to move, such that the linkage mechanism drives the iron core to move up and down, so as to adjust the trip current of a product. The direct-acting electromagnetic trip device has a simple and compact structure, safe and stable performances and is easy to fit.
