发明名称 RAPID ELECTRIC-ARC EXTINGUISHING ASSEMBLY IN CIRCUIT- BREAKING DEVICES SUCH AS ELECTRIC CIRCUIT BREAKERS
摘要 <p>41PR-6143 RAPID ELECTRIC-ARC EXTINGUISHING ASSEMBLY IN CIRCUIT-BREAKING DEVICES SUCH AS ELECTRIC CIRCUIT BREAKERS 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.</p>
