ASSIST DEVICE TO IMPROVE THE DIELECTRIC STRENGTH OF CIRCUIT BRAKER

摘要

PURPOSE: An auxiliary circuit breaker is provided to easily intercept current between tow arc contacts by surrounding a first arc contact when intercepting a fault current to block the flow of electrons. CONSTITUTION: An auxiliary circuit breaker includes an attractors(200), an insulating cover(100), and a guide bar(300). A first insulating cover is comprised of a first cover body and a first blade. The first cover body surrounds the outer circumference of one side of a first arc contact(1). The insulating cover is decided according to the first arc contact. The insulating cover is moved in horizontal direction and is ascended in oblique direction at the end of the first arc contact.
