Problems solved by technology

Moreover, most of the existing electric control cabinets use commercially available anti-rust paint for anti-corrosion. When the external environment is humid during the heat dissipation process, not only the anti-corrosion effect is poor, but also the hot air discharged contains a large amount of VOC, which pollutes the air.

Abstract

The invention discloses an electric control cabinet and an assembly method thereof. The cabinet body of the electric control cabinet comprises an explosion-proof housing and a ventilation housing andis characterized in that the explosion-proof housing is a rectangular parallelepiped housing and defines an explosion-proof cavity; the ventilating housing is located at one side of the explosion-proof housing and forms a ventilation cavity with the explosion-proof housing; the explosion-proof housing is provided with a mounting hole at a side close to the ventilation housing; the explosion-proofcavity is in communication with the ventilation cavity by the mounting hole; a heat dissipation device is mounted on the mounting hole; the inner walls of the explosion-proof housing and the ventilation housing are first sprayed with zinc-rich primer, and then the surface of the zinc-rich primer is coated with an anticorrosive material layer. The cooling and heat dissipation function of the electric control cabinet is efficient, and the content of VOC in the discharged hot air is significantly reduced so as to be more environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of electric control cabinets, in particular to an electric control cabinet and an assembly method thereof. Background technique [0002] The electric control cabinet is the final equipment of the power distribution system, and the electric control cabinet is the general name of the motor control center; the electric control cabinet is used in the occasions where the load is relatively scattered and there are few circuits, and 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. In order to protect the equipment and circuits in the electric control cabinet and prevent them from being damaged by the outside world, the electric control cabinet mostly adopts a sealed structure. Poor, resulting in failure of equipment and circuits ...
