Multifunctional low-voltage distribution box

Abstract

The invention discloses a multifunctional low-voltage distribution box, which comprises a box body assembly, a box cover assembly, a heat dissipation assembly and a filtering base. The multifunctionallow-voltage distribution box is simple in structure and convenient use. The distribution box main body is provided with a sealing groove matched with the cover plate, so that the sealing effect between the cover plate and the distribution box main body is better. The air in the distribution box main body can be discharged from a heat dissipation opening through a heat dissipation fan in the heatdissipation assembly, so that ventilation and heat dissipation can be effectively carried out on the interior of the distribution box main body, and the ventilation and heat dissipation efficiency isimproved. Meanwhile, a dustproof plate and an arc-shaped baffle plate are arranged above the heat dissipation opening, so that dust can be effectively prevented from entering the distribution box mainbody from the heat dissipation opening, thereby achieving a dustproof effect. In addition, the air entering from an air inlet hole and an air inlet groove can be filtered through a filter plate on the filtering base, so that dust in the air cannot enter the distribution box main body, and the dustproof effect is better.

Description

technical field [0001] The invention relates to a multifunctional low-voltage distribution box, which belongs to the technical field of distribution boxes. Background technique [0002] The distribution box is a large number of parameters on the data, and generally constitutes a low-voltage forest. According to electrical wiring, it is required to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal box or on a screen width to form a low-voltage distribution box. box. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. The distribution box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, not limited by the site, widely used, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect. Switchgear, measuri...

AI Technical Summary

Problems solved by technology

Switchgear, measuring instruments, protective appliances and auxiliary equipment are assembled in a closed or semi-closed metal box. When the weather temperature is high, the existing low-voltage distribution box cannot independently ventilate and dissipate heat, making the ventilation and heat dissipation efficiency too low. It does not have a good ventilation and heat dissipation effect, and it is easy to cause damage to the electronic components inside. Moreover, when the existing distribution box is ventilated, when there is a lot of dust in the air, the air enters the inside of the distribution box. Dust will remain inside the distribution box, making the distribution box need to be cleaned
