The distribution box in power engineering is a massive parameter in data. It generally constitutes a low-voltage forest according to electrical wiring. It requires that switchgear, measuring instruments, protective electrical appliances and auxiliary equipment be assembled in a closed or semi-enclosed metal cabinet or on a screen to form a low-voltage distribution box. During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. The distribution box has the characteristics of small size, easy installation, special technical performance, fixed position, unique configuration function, no site restrictions, relatively common application, stable and reliable operation, high space utilization, small footprint and environmental protection effect.

[0003] The existing distribution box is prone to dust accumulation during long-term static use. The accumulated dust may enter the interior of the box and cover the surface of electrical components or connectors, causing problems such as poor contact, short circuit or leakage, increasing the risk of electrical fires. In addition, the humidity inside the distribution box will increase after raining. The increased humidity will cause the electrical equipment inside the distribution box to become damp, such as wires, terminal blocks, switches, etc., resulting in a decrease in the insulation performance of the electrical equipment, increasing the risk of leakage, short circuit and other faults. In view of the above problems, a distribution box for power engineering is proposed to solve them. Utility Model Content

[0028] Specifically, the dehumidification component 4 includes an installation box body 401, which is fixedly connected to the lower end of the right side surface of the box body 1, and two groups of first fans 402 are fixedly installed inside the installation box body 401. A heating resistor 403 is fixedly connected to the inside of the installation box body 401 and the output end of the first fan 402, and a dustproof mesh cover 404 is fixedly connected to the side of the installation box body 401 away from the heating resistor 403. It should be noted that the top of the installation box body 401 is inclined. This design can smoothly drain rainwater to prevent rainwater from accumulating on the installation box body 401 and causing corrosion damage to the installation box body 401.

[0029] Specifically, the dust removal assembly 7 includes a dust removal box body 701, which is fixedly connected to the bottom of the box body 1. A dust suction pipe 702 is fixedly connected to the lower left end of the dust removal box body 701. The end of the dust suction pipe 702 passes through the left side wall of the box body 1 and is connected to the interior of the box body 1. A filter bag 703 is fixedly installed inside the dust removal box body 701. The filter bag 703 can effectively capture fine particles and particulate matter in the dust-containing gas and has good filtration efficiency.

[0034] Working principle: When it rains and the humidity inside the box 1 is high, when the induction switch 17 detects that the humidity inside the box 1 reaches the threshold, the heating resistor 403 in the dehumidification component 4 will generate heat. At this time, the first fan 402 blows heat into the inside of the box 1 to increase the temperature inside the box 1. The high temperature will evaporate the moisture into water vapor, and the water vapor will be absorbed by the dehumidification bag 9 through the air vent 10, so that the inside of the box 1 remains dry. When the second fan 706 is started, the dust removal box 701 generates negative pressure, and the dust-containing gas enters the dust removal box 701 through the dust suction pipe 702. When passing through the filter bag 703, the dust is blocked and accumulated in the dust removal box 701, and the purified air is discharged through the exhaust pipe 704.
