Outdoor box-type protection and heat dissipation device for transformer

Abstract

The invention discloses an outdoor box-type protection and heat dissipation device for a transformer. The device includes a box body, a door body hinged to one side of the box body and capable of being opened and closed and a cover body covering the box body from the above. The box body is therein provided with a cavity accommodating electrical apparatus elements. The cover body is an arc face having a higher middle part and two lower sides. The horizontal projection of the cover body covers the horizontal projection of the box body. The two side walls of the box body are each provided with a plurality of strip-shaped heat dissipation holes. The upper edge of each heat dissipation hole is connected with an arc-shaped blocking board extending downwards. A heat dissipation mechanism is connected to the lower side of each heat dissipation hole. The bottom of the box body is provided with four support mechanisms. According to the invention, the heat dissipation hole shielding degree can be controlled in real time according to environmental humidity and the outdoor box-type protection and heat dissipation device can be mounted in an outdoor working environment stably. A dustproof effect and a moisture-proof effect are achieved. The outdoor box-type protection and heat dissipation device has advantages of low cost and simple installation, and is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the technical field of electric equipment. More specifically, the present invention relates to an outdoor box-type transformer protection and heat dissipation device. Background technique [0002] Due to its small size, light weight, low noise and low loss, and high power supply reliability, outdoor box-type transformers are widely used in 10kV distribution networks. Since outdoor box-type transformers are mostly installed in the open air, and some are installed in mountainous areas, the working environment is complex, the ground is uneven, and the inclination of electrical components may cause vibration, which brings great hidden dangers to safe power supply and normal operation of equipment. In humid weather, the air humidity is high, and due to the poor heat dissipation and protection of the box, the discharge of high-voltage electrical components is prone to occur, thereby burning the electrical components and causing powe...

Since outdoor box-type transformers are mostly installed in the open air, and some are installed in mountainous areas, the working environment is complex, the ground is uneven, and the inclination of electrical components may cause vibration, which brings great hidden dangers to safe power supply and normal operation of equipment. In humid weather, the air humidity is high. Due to the poor heat dissipation and protection of the box, the discharge of high-voltage electrical components is prone to occur, thereby burning the electrical components and causing power outages.
