Problems solved by technology
[0005] The purpose of the present invention is to solve the problem in the prior art that "existing power distribution cabinet door panels are rarely equipped with explosion-proof structures during use. Once an explosion occurs inside the power distribution cabinet, it is easy to cause damage to objects and pedestrians around the power distribution cabinet." damage, and the heat dissipation of the existing power distribution cabinet is not good enough", so an explosion-proof structure for the door panel of the medium voltage power distribution cabinet is proposed

The invention discloses an explosion-proof structure of a medium-voltage power distribution cabinet door plate. The explosion-proof door plate comprises a cabinet body, a door plate body and an explosion-proof plate, the side wall of the door plate body is connected to the inner wall of the cabinet body through hinges, an explosion-proof cavity is formed in the door plate body, and the explosion-proof plate penetrates through the left side wall of the door plate body and is connected into the side wall of the door plate body in a sliding mode; a mounting groove is formed in the center of the right side wall of the explosion-proof plate, a touch switch is arranged on the side wall of the mounting groove, a threaded rod is fixedly mounted in the center of the mounting groove, the other end of the threaded rod is in threaded connection with a rotating cylinder, and the other end of the rotating cylinder is rotatably connected to the inner wall of the explosion-proof cavity; and a second spring is fixedly installed on the inner wall of the rotating cylinder, and the other end of the second spring abuts against the end, away from the explosion-proof plate, of the threaded rod. Accordingto the invention, impact force generated by explosion is prevented from rushing through the door plate body and hurting pedestrians around the cabinet body.
Description
technical field [0001] The invention relates to the technical field of a door panel of a power distribution cabinet, in particular to an explosion-proof structure of a door panel of a medium-voltage power distribution cabinet. 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 power distribution cabinet is a general term for the motor control center. The power distribution 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 nearest load. This level of equipment shall provide protection, monitoring and control of the loa...
