Weather manual simulation room with icing wind tunnel

Abstract

The invention relates to a weather manual simulation room. The weather manual simulation room comprises a refrigeration device for cooling air in a weather room, a low-speed wind tunnel arranged in the weather room, an ice coating water and steam generation device and an atomization spraying device connected with the ice coating water and steam generation device and located in the weather room; a testing region is connected with a wind outlet of the low-speed wind tunnel and an air returning opening is formed in the testing region on the opposite side of the wind outlet; an inner wall of the weather room is used as a wind returning region of the low-speed wind tunnel; 0-10m / s uniform wind is formed in the testing region; and the ice coating water and steam generation device comprises an ice coating water generation device and an ice coating steam generation device, which are used for introducing water and steam with certain pressure into the atomization spraying device respectively to be mixed, so that water mist drops with certain quantity and grain diameters are sprayed out in the testing region. The weather manual simulation room lays foundation for research of the influences of wind on equipment icing; and meanwhile, by using the weather manual simulation room, a plurality of types of icing types including glaze, rime, mixed rime, wet snow and the like can be formed on the surface of a test sample.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a climate artificial simulation room with an ice wind tunnel. Background technique [0002] The icing disaster of outdoor power transmission and transformation equipment seriously threatens the safe operation of the power system. In recent years, in order to study the icing growth mechanism of power transmission and transformation equipment and the impact of icing on the external insulation of power transmission and transformation equipment, universities and scientific research institutions at home and abroad have established their own artificial climate simulation laboratories and carried out a large number of transmission wires. , Insulators and casing icing, ice melting and ice flash tests. However, when icing power equipment in climate artificial simulation laboratories, power equipment is only iced in the absence of wind. At present, it is believe...

Problems solved by technology

However, when icing power equipment in the artificial climate simulation laboratory, the power equipment is only iced in the absence of wind. At present, it is believed that low-speed wind (3~7m / s) has a significant impact on the shape and growth of ice coating. However, the experimental research has hardly considered the influence of wind, mainly because it is difficult to form a uniform wind speed in the artificial climate simulation laboratory, and it is impossible to carry out relevant experimental research work. Therefore, the data and curves of the influence of wind on icing of power equipment have not been obtained so far.
