Embodiment Construction
[0043] Such as Figure 1~8Among them, a natural air-cooled device for an air-core reactor, which includes a drainage device 1 and an air guiding device 2; The drainage device 1 is arranged at intervals between multiple air-core reactors; the drainage device 1 guides the hot air inside the air-core reactor in a fixed direction, and the air guide device 2 is located at the top to guide the hot air to the surroundings. The structure is simple, by installing a drainage device 1 between multiple stacked air-core reactors, the uppermost drainage device 1 is connected to the air guide device 2, and the hot air generated when the air-core reactor is working is drawn out to the outside through the drainage device 1 , and as a connecting piece between two superimposed air-core reactors, the hot air that rises upwards is guided to the surroundings by the air guide device 2, and the heat dissipation effect is good, the installation is convenient and quick, and the structure is stable.

A natural air-cooling device for an air-core reactor, which includes a drainage device and an air-guiding device. By setting the drainage device between multiple stacked air-core reactors, the uppermost drainage device is connected to the air-guiding device, and the drainage device will The hot air generated when the air-core reactor is working is led out to the outside, and used as a connecting piece between the two superimposed air-core reactors, the hot air that rises upward is guided to the surroundings by the air guide device and diffused. The invention overcomes the problems of poor heat dissipation effect and unstable superimposed installation structure of the original air-core reactor, and has the characteristics of simple structure, good heat dissipation effect, convenient and fast installation and stable structure.
Description
technical field [0001] The invention belongs to the technical field of heat dissipation of electrical components, and relates to a natural air cooling device and method for an air-core reactor. Background technique [0002] Reactors are used for protection in power transmission and distribution lines to limit the impact of overvoltage or overcurrent, which involves a reactor with a hollow structure with a large power frequency. During installation and use, it is often placed horizontally alone, or , multiple superimposed placements, wherein although the superimposed placement saves space, the heat dissipation effect is not ideal, and the stability of the structure is reduced after the superposition. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a natural air-cooling device and method for an air-core reactor, which has a simple structure and adopts a drainage device between a plurality of stacked air-core reacto...
