Description
Technical field
The utility model relates to low-voltage circuit breaker technical field, is specifically related to a kind of breaker structure utilizing movable contact trigger mechanism rapid-releasing.
Background technology
Low-voltage circuit breaker can be used for the short circuit current protection of circuit.Concerning some current limiting type circuit breakers, before the physical fault short circuit current of circuit reaches circuit prospective short circuit current peak value, moving contact will be scolded out under the effect of electrodynamic repulsion force, produces electric arc, thus the further rising of limiting short-circuit current.Then the electromagnetic protection mechanism of circuit breaker can be with pneumatic operating mechanism action, circuit breaker tripping separating brake, extinguish arcs, cutting-off of short-circuit fault current.
In reality, after moving contact is scolded out generation electric arc by electrodynamic repulsion force, because the hysteresis quality of electromagnetic mechanism action needed with the operate time of self, electromagnetic mechanism can not make mechanical unlocking and breaker open operation timely, thus fall after rise after causing the burned for long time of electric arc between dynamic and static contact and moving contact to scold out, moving contact can be made time serious to fall rear and fixed contact secondary closure after rise, cause contact melting welding, purpose of breaker failure.
