A distribution cabinet

Abstract

The invention discloses a power distribution cabinet, comprising a cabinet body, a heat dissipation mechanism is arranged in the cabinet body, the heat dissipation mechanism includes a fixing plate, the fixing plate is fixedly connected to the inner wall near the upper end of the cabinet body, and the fixing plate The wall is fixedly connected with an installation box, the bottom of the installation box is fixedly connected with a placement box, the inside of the placement box is equipped with cooling liquid, and the upper inner wall of the placement box is elastically connected with a magnetic slide plate through the first memory metal sheet. The inner wall of the box is slidably connected with two permanent magnet blocks that attract different poles of the magnetic slide plate, and the side walls of the two permanent magnet blocks are fixedly inserted with copper frames, and the side walls of the installation box and the placement box are fixedly connected There are two magnetic plates with opposite poles attracting each other. According to the change of temperature, the present invention can automatically radiate heat and cool down the inside of the power distribution cabinet, ensuring that the power components in the cabinet will not be damaged due to high temperature, and can also prevent rainwater from entering the cabinet, ensuring that the power components in the cabinet will not short circuit.

Description

technical field [0001] The invention relates to the technical field of power communication equipment, in particular to a power distribution cabinet. Background technique [0002] With the continuous development of power communication technology, the use of power distribution cabinets is becoming more and more extensive. The power distribution cabinets are mainly used to hold some power components. Most of the power distribution The electric cabinet has the following problems: [0003] 1. The power components in the power distribution cabinet will generate a lot of heat when they work. Moreover, in the open air environment, when encountering high temperature weather, the temperature in the power distribution cabinet will be higher, and it is easy to burn out the internal parts of the power distribution cabinet. Power components will cause harm to the transmission of communication circuits. In severe cases, the internal power components may catch fire and cause a fire. Howeve...

Problems solved by technology

[0003] 1. The power components in the power distribution cabinet will generate a lot of heat when they work. Moreover, in the open air environment, when encountering high temperature weather, the temperature in the power distribution cabinet will be higher, and it is easy to burn out the internal parts of the power distribution cabinet. Power components will cause harm to the transmission of communication circuits. In severe cases, the internal power components may catch fire and cause a fire. However, the existing power distribution cabinets generally only have some small ventilation openings on the side walls of the cabinet. The interior of the electric cabinet is still in a nearly airtight state, and the heat dissipation effect is not obvious;

[0004] 2. After opening some vents in the power distribution cabinet, in rainy days, rainwater will easily enter the power distribution cabinet, which will easily cause a short circuit of the internal power components, interrupt the transmission of power, and bring inconvenience to the communication work
