Abstract
A relay is provided with a housing, a coil arranged inside the housing, a fixed terminal, and a movable member. The housing is filled with an insulating liquid refrigerant, and the coil and the movable member are immersed in the liquid refrigerant, and at least a fixed contact of the fixed terminal is immersed in the liquid refrigerant. Heat generated in the coil, the movable member, and the fixed terminal is cooled by the liquid refrigerant, and thus the efficiency of cooling the relay is improved.
Claims7
An electric apparatus comprising:
