Rapid electric-arc extinguishing assembly in circuit-breaking devices such as electric circuit breakers |
摘要 |
A rapid arc extinguishing assembly includes an arc chute comprising a large number of essentially parallel deionizing plates each in form of thin magnetically permeable, electrically conductive plates bent in U-shape, with the curve of the U facing the circuit breaker contacts and the arms thereof insulated from each other by a thin insulation sheet. To promote arc extinction by the arc chute and accelerated breaker contact separation, the breaker contacts are flanked by a magnetic assembly comprising opposed columns of parallel, spaced ferromagnetic plates embedded in an insulating material. The columns may be magnetically coupled by a yoke to create a closed slot in which the breaker movable contact travels.
