ARC RESTRICTING DEVICE FOR CIRCUIT BREAKER |
摘要 |
A circuit breaker having means for quickly opening a pair of contacts, a U-shaped flux board which surrounds the conductors that have contacts attached to the end portions thereof, so that the electromagnetic repulsive force produced by the electric current that flows through the opposing conductors in opposite directions relative to each other, will be added to the operation of the contact-opening means. The circuit breaker of the invention is further equipped with arc shielding members surrounding the contacts, so that the arc established across the contacts will not stretch to the conductors in the vicinities of the contacts, and so that the arcing voltage is greatly increased. |
