Abstract
The utility model discloses an explosion-proof type double-loop variable frequency transformer low voltage protection case which comprises an explosion-proof shell welded by a steel plate. The explosion-proof shell comprises three cavities which are mutually independent, i.e. two wire outlet cavities and a main cavity respectively. The two wire outlet cavities are respectively arranged on two sides of the main cavity. A door cover is arranged in front of the main cavity. A flange is arranged on the external side wall behind the main cavity. The main cavity is internally provided with a grounding screw. Two opposite side walls inside the main cavity are both provided with, from the top to the bottom, three main loop connection posts, four control connection posts, two nine-core connection posts and one leakage detection unit. Each main loop connection post is connected with a current mutual inductor. The lower part of the internal side wall of the door cover is provided with an integrated protector. Each wire outlet cavity is internally provided with a branching flange, a wire pressing cavity and a control cable wire pressing cavity. The branching flange is provided with a branching flange cover. The wire pressing cavity is provided with a pressing disc. Each wire outlet cavity is provided with a wire outlet cavity flange. The control cable wire pressing cavity is provided with a control cable pressing disc.
