Description

Technical Field

[0001] The invention relates to the technical field of electrical installation, in particular to an electrical installation box with good ventilation effect. Background Art

[0002] An electrical installation box is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. The existing electrical installation boxes have poor heat dissipation effect, which can easily lead to malfunction or even damage of electrical components in the electrical installation box due to overheating.

[0003] The invention patent with patent number CN202211356029.4 discloses a distribution box. The space between the heat dissipation port and the baffle of the invention is conducive to the heat dissipation of the box. When the electrical components are initially installed, the baffle rotates to clamp and position the electrical components, which is convenient for personnel to install the electrical components on the box. In the distribution box, when the baffle does not squeeze the filter plate, the filter plate extends into the heat dissipation port, and the filter plate gradually contacts the outer side of the baffle. The filter plate scrapes off the dust attached to the baffle, reduces the dust on the surface of the baffle when it is tilted and rotated, and enters the box body, ensuring that the electrical components in the box are In order to ensure the normal operation of the components, in the distribution box, after the filter plate is extended, one side of the filter plate will always be located on the baffle, and the filter plate blocks the heat dissipation space between the baffle and the heat dissipation port, thereby avoiding the problem of dust or foreign matter entering the box along the heat dissipation port when the baffle opens the heat dissipation port to dissipate heat to the box, thereby ensuring that the operation of the electrical components inside the box is not affected. Although this patent solves the above problems, there is still a problem that the ventilation effect is not good enough, which can easily cause damage to the internal electrical components. Therefore, it is very necessary to design an electrical installation box with good ventilation effect that can effectively prevent damage to the electrical components. Summary of the invention
