Box-type protecting radiating device for transformer

Abstract

The invention discloses a box-type protecting radiating device for a transformer. The protecting radiating device comprises a box, a door and a cover, wherein the door can be opened and closed and is hinged on one side of the box; the cover is covered above the box; a chamber for accommodating an electric element is arranged in the box; the cover is arranged as an arc-shaped surface high in middle and low in two sides; a horizontal projection of the box is covered by the horizontal projection of the cover; a plurality of bar-shaped radiating holes are respectively formed on the two side walls of the box; downward extending arc-shaped baffles are externally connected with the upper edges of the radiating holes; radiating mechanisms are internally connected with the lower edges of the radiating holes; four support mechanisms are arranged at the bottom of the box. The shielding degree of the radiating holes can be controlled in real time according to the environmental humidity; the box-type protecting radiating device is stably arranged under an outdoor working environment; the box-type protecting radiating device is dustproof and damp-proof, has the advantages of low cost and easy mounting, and is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of electric equipment. More specifically, the present invention relates to a protective heat dissipation device for a box-type transformer. Background technique [0002] Due to its small size, light weight, low noise and low loss, and high power supply reliability, box-type transformers are widely used in 10kV distribution networks. Since box-type transformers are usually 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 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 power outages. Therefore, there...

Since box-type transformers are usually 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. When the weather is high, 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.
