Abstract

The invention discloses a power distribution cabinet with a line protection and repair function, and belongs to the field of power distribution cabinets. According to an adopted scheme, a tensile force is generated on a cable through the displacement of an electronic element, and the cable pulls a circular pressing plate in a fixed cylinder downwards, a repairing protection device is extruded through movement of the circular pressing plate and a circular ejection plate, so that a wire adhesive is uniformly adhered to a damaged part at the outer end of the cable, and the wire adhesive in an insulating latex layer is extruded to the outer end of the cable through a through hole, so that the wire adhesive is uniformly adhered to the damaged part of the outer end of the cable; the influence ofthe cable on current transmission is reduced, the damaged part of the cable is repaired, and high temperature generated when the cable is damaged and short-circuited is transferred to a soluble separation membrane through an arc-shaped limiting plate and a heat conduction rod for melting, so that an aqueous solution and ammonium salt particles in a reaction cavity are fused to absorb heat, and the wire adhesive is quickly solidified, therefore, the repairing efficiency of the cable is improved.

Description

technical field [0001] The invention relates to the field of power distribution cabinets, more specifically, to a power distribution cabinet with the function of line protection and repair. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. The load provides protection, monitoring and control. [0003] The switchboard (box) should be made of non-combustible materials; the production site and office with low risk of electric shock can be installed with open ...
