Abstract

The invention provides a tripping device, belonging to the field of circuit protection devices. The tripping device comprises a mutual inductor, a button, a first transmission mechanism, a second transmission mechanism, an elastic piece, and a locking lever, wherein the button is connected with the first transmission mechanism, the elastic piece is at one side of the first transmission mechanism,the button can drive the first transmission mechanism to compress the elastic piece, the locking lever is at the other side of the first transmission mechanism, the locking lever can rotate and propsagainst the first transmission mechanism, the button, the second transmission mechanism and the mutual inductor are arranged in sequence, the button can drive the second transmission mechanism to compress the mutual inductor, the locking lever is between the button and the second transmission mechanism, the mutual inductor can push the second transmission mechanism, the locking lever can be separated from the first transmission mechanism under drive of the second transmission mechanism, and the first transmission mechanism can push the button under elastic recovery role of the elastic piece. The tripping device solves problems of complex structure, large volume, and high manufacture cost in the prior art.

Description

technical field [0001] The present invention relates to the technical field of circuit protection devices, in particular to a tripping device. Background technique [0002] The residual current trip protection device is an effective protective measure to prevent personal electric shock, electrical fire and electrical equipment damage. The residual current trip protection device usually transmits a signal to the electromagnetic coil, so that the armature on the electromagnetic coil pops up and directly hits the trip bar of the circuit breaker, thereby triggering the tripping of the circuit breaker. [0003] However, as the capacity of the circuit breaker increases, the tripping force required by the circuit breaker will also increase. If the electromagnetic coil armature is still used to directly hit the trip bar of the circuit breaker, the impact force of the electromagnetic coil needs to be increased, which in turn will increase the force of the electromagnetic coil. At th...
