Description

A power distribution cabinet with heat dissipation function

Technical Field

The utility model belongs to the technical field of power distribution cabinets, and particularly relates to a power distribution cabinet with a heat dissipation function.

Background Art

The distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or on a screen according to the requirements of electrical wiring. The distribution box can reasonably distribute electrical energy and facilitate the opening and closing of the circuit; it has a high level of safety protection and can intuitively display the conduction status of the circuit; it is easy to manage and is conducive to maintenance when a circuit failure occurs; in normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches, and in the event of a failure or abnormal operation, the circuit can be cut off or an alarm can be issued with the help of protective electrical appliances. The distribution box can display various parameters in its operation with the help of measuring instruments, and can also adjust certain electrical parameters, and give prompts or signals for deviations from normal working conditions. It is often used in various power generation, distribution and substations.

At present, a Chinese utility model with announcement number: CN207303784U discloses a distribution box, including a box body, wherein the box body is composed of a top plate, a bottom plate, two side plates, and a back plate, an opening is provided at one end of the box body, a box cover is provided at the opening, and mounting grooves are provided on the top plate and the bottom plate facing the side walls inside the box body and close to the side plates; U-shaped elastic connecting parts are provided on the side plates near the top plate and the bottom plate, and a clamping block cooperating with the mounting groove is provided on the elastic connecting part, and an extrusion block extending toward the top plate from the elastic connecting part near the top plate; when the clamping block is embedded in the mounting groove, the extrusion block contacts the top plate.

However, the above device still has certain defects. For example, the electrical components in the distribution box are more sensitive to the ambient temperature during operation. Since the electrical components themselves generate a certain amount of heat during operation, when this heat is mixed with the ambient temperature and cannot be discharged from the distribution box, it is easy for the electrical components to be damaged due to high temperature. Although general distribution boxes are equipped with heat dissipation ports and cooling fans, the positions of the heat dissipation ports are fixed. When dissipating heat, it can only dissipate heat towards the electrical components in a fixed direction, which leads to other electrical components that are not opposite to the heat dissipation ports not being effectively cooled and radiated, resulting in poor heat dissipation effect. In addition, general heat dissipation windows do not have effective filtering devices, which easily lead to external dust and impurities entering the distribution box, causing the electrical components to be damaged by dust and impurities. Based on the above problems, we provide a distribution cabinet with heat dissipation function.
