Distribution box for electrical engineering

Abstract

The invention discloses a distribution box for electrical engineering, and belongs to the electrical technical field. The distribution box comprises a box body, a box door and a single-chip microcomputer. The box door is mounted at the left corner angle of the front end of the box body, an opening is formed at the lower portion of the box body, and the single-chip microcomputer is fixed at the inner bottom end of the box body. A cooling driving mechanism is mounted at the lower end of the box and comprises a base plate, the bottom plate is fixed with the lower end of the box body, and an air duct is formed on the bottom plate. A cover plate is arranged at the upper end of the bottom plate, a transmission block is fixed at one end of the cover plate, and a first servo motor is fixed on therear inner wall of the box body and is electrically connected with the single-chip microcomputer. A driving gear is fixed to the output end of the first servo motor, and a plurality of evenly-distributed driven gears are fixed to the upper end of the cover plate and the upper end of the transmission block. The distribution box can automatically cool according to a temperature threshold value, meanwhile, when the strong wind and heavy rain are detected, closes the air holes automatically, so that the interior of the distribution box is not rusted easily.

Description

technical field [0001] The invention relates to the field of electrical technology, and more specifically relates to a distribution box for electrical engineering. Background technique [0002] The distribution box is a large number of parameters in the data. It generally constitutes a low-voltage distribution box. box. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. [0003] 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. It can distribute electric energy reasonably, facilitate the opening and closing operation of the circuit, has a high level of safety protection, and can intuitively display the conduction state of the circuit. [0004] In the pri...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, blowers are mostly used for distribution boxes. When the distribution box is in working condition, the blower keeps working to reduce the temperature in the distribution box, which wastes electric energy, but the existing distribution box cannot detect The temperature in the distribution box cannot realize the operation of the cooling system by itself according to the temperature range. In the prior art, air holes are set outside the distribution box. Since the air holes are open all the year round, it is easy to cause power distribution problems after wind and rain. Corrosion inside the box, easy to produce a lot of rust
