Waterproof power distribution cabinet

Abstract

The invention relates to the technical field of power distribution cabinets, and discloses a waterproof power distribution cabinet which comprises a cabinet body. The interior of the cabinet body is hollow, ventilation devices are fixedly installed at the two sides of the cabinet body, and movable plates are arranged at the two sides, close to the ventilation devices, of the cabinet body. Air passing openings are formed at the positions, right facing the ventilation devices, of the movable plates, and an upper slide way is movably mounted at the upper end of the movable plate. According to thepresent invention, heat is dissipated through a water collecting hopper and a water inlet pipe, the situation that after the ventilation pipe is closed, the internal heat dissipation effect is poor,and consequently the device is burnt out due to high temperature is avoided; cold water in the water inlet pipe is tightly attached to one side of the fixing plate, heat generated by the device achieves the cold-heat exchange through the fixing plate and the pipe wall of the water inlet pipe, and then heat generated by the device is conducted into a water containing frame through the flowing waterand is discharged through a water discharging pipe, so that the heat dissipation effect after the ventilation pipe is closed is improved, the protection effect of the power distribution cabinet is improved, and the damage probability of the power distribution device is reduced.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a waterproof power distribution cabinet. Background technique [0002] The power distribution cabinet is the general name of the center of the motor control system. The power distribution cabinet is generally used in places with fewer circuits and relatively scattered loads, while the motor control center is generally used in places with many circuits and relatively concentrated loads. The power of a certain circuit of the equipment is distributed to the nearest load, and the power distribution cabinet can provide protection, monitoring and control for the load. [0003] There are usually a lot of circuit equipment and lines inside the power distribution cabinet. In order to avoid too much heat and damage to the equipment when these devices are working, ventilation ports are generally provided on both sides of the cabinet for heat dissipation. These ventilatio...
