VACUUM VALVE AND AN INSULATION HOUSING, CAPABLE OF IMPROVING THE RELIABILITY OF INDOOR AND OUTDOOR SWITCHES AND A CIRCUIT BREAKER

摘要

PURPOSE: A vacuum valve and an insulating housing is provided to improve the insulation performance by preventing the generation of the bubble at an interface between the outer surface of the vacuum valve and the inner surface of the insulating housing.;CONSTITUTION: A vacuum valve(120) is molded with soft polymer insulation rubber. An insulation housing(110) is made of hard polymer insulation materials. A vacuum valve is assembled inside the insulation housing by a screw. The outer diameter and the length of the vacuum valve are greater than those of the insulation housing. The end of the molding unit of the vacuum valve is inclined with a preset angle to easily discharge the bubble.;COPYRIGHT KIPO 2010
