ELECTRODE ASSEMBLY AND VACUUM INTERRUPTER INCLUDING THE SAME

摘要

Disclosed are an electrode assembly and a vacuum interrupter including the same. The electrode assembly is provided in an insulating vessel which is in a vacuum state, and switches a main circuit. The electrode assembly includes a first electrode plate, a second electrode, a coil conductor, a first conductor, and a second conductor. The coil conductor induces a flow of a current in a first direction and a second direction between the other side of the first conductor connecting pin and the one side of the second conductor connecting pin, and the first direction and the second direction are mutually opposite circumference directions. Accordingly, an arc gas is effectively spread by using mutually opposite flows of currents in a circumference direction, thereby enhancing break performance.
