AN IMPROVED ARC QUENCHING IN ELECTRICAL DEVICE

摘要

In one implementation, the present invention is addressed to a circuit breaker for rapidly cooling and extinguishing an arc. The circuit breaker with an arc runner flanked to the rear end of moving conductor assembly such that it acts as an electrical conductor having a sloped bend facing the moving conductor. During arcing as the conductor opens the arc quickly jumps onto the arc runner leaving the electrical moving conductor. Then the runner smoothly commutes the arc into the deionizing splitter plate using the magnetic force from flow of electricity. Moving conductor moves radially in between the arc runner which has a stepped bend at both sides. This special arrangement will reduces the arc concentration around the moving conductor, and increases upward forces acting on the moving conductor during arcing which makes it open faster and thus helps in faster quenching.
