Abstract
An explosion-proof control box of the utility model relates to the technical field of electrical equipment and is composed of a box body, a box cover, a wire inlet, a wire outlet, and operation handles. One side of the upper part of the box body and one side of the box cover are hinged together through an articulated shaft. Screw rods and ports are uniformly distributed in the rims of the box cover and the top part of the box body for connection. One side of the box body is provided with the wire inlet, while the other side of the box body is provided with the wire outlet. More than one operation handle is arranged in the top part of the box cover. Operation rods of the operation handles vertically penetrate through the box cover and connected with bearings fixed on the box cover. The bottom ends of the operation rods are used cooperatively with switches on a circuit breaker inside the box body. According to the explosion-proof control box of the utility model, the circuit breaker, a contactor, and a magnetic force starting device are all mounted inside the explosion-proof box body so that electric arcs generated inside the box body cannot be transmitted to the outside of the box body. Therefore, explosions causing personal and property loss cannot be generated. The explosion-proof control box can be mounted in explosive gas environments and stand close to equipment; and the explosion-proof control box is convenient to operate and saves the cost.
