Alternating current low-voltage distribution cabinet

Abstract

The invention discloses an AC low-voltage power distribution cabinet, which comprises a casing, an exhaust fan and supporting legs; a water tank is arranged on the top of the casing, and a funnel-shaped collector is communicated with the top of the water tank; the collector is fixed horizontally in the collector There is a filter screen; the shell is provided with a heat collecting plate, and a cooling pipe is fixedly installed on the heat collecting plate, and the cooling pipe is coiled on the surface of the heat collecting plate, and the inlet of the cooling pipe is connected to the water tank; both sides of the shell A ventilation groove is provided, and two first dust baffles and a second dust baffle parallel to each other are vertically fixed in the ventilation groove, and the first dust baffle and the second dust baffle are provided with mutually staggered ventilation holes, A rainwater isolation board is arranged on the outside of the ventilation groove. The invention has a simple structure, utilizes rainwater for water cooling and heat dissipation, is environmentally friendly and energy-saving, increases the heat dissipation mode, improves heat dissipation efficiency, and the ventilation groove increases the ventilation effect, avoids large internal moisture, and prolongs the service life.

Description

technical field [0001] The invention relates to electric equipment, in particular to an AC low-voltage power distribution cabinet. Background technique [0002] With the rapid development of the economy, industrial production and people's life are inseparable from the use of electricity, and the role of electricity is increasing, so the related power distribution equipment is also used more and more widely. Outdoor power distribution cabinet is an important power distribution equipment, which is widely used in oil exploration, oil refining, chemical industry, military industry and other dangerous environments, as well as offshore oil platforms, oil tankers and other places for general lighting and operational lighting. With the widespread use of outdoor power distribution cabinets, people's requirements for it are getting higher and higher. Therefore, outdoor power distribution cabinets must be gradually improved to adapt to the development of society. [0003] The existing...

AI Technical Summary

Problems solved by technology

[0003] The existing outdoor power distribution cabinet includes a large cabinet body. The power distribution cabinet is generally arranged outdoors and belongs to public facilities. The internal power equipment generates a lot of heat during operation. If the heat is not dissipated in time, the internal temperature will rise and affect the normal operation of the equipment. It will affect the normal use of the power distribution cabinet and reduce its service life; in rainy days, due to the large amount of moisture in the air, after entering the power distribution cabinet, the circuit will be damaged and the internal equipment will be corroded, which is not conducive to the use of the power distribution cabinet.
