Background
With the large development in the western world and the large development of energy economy, more and more medium-voltage electrical equipment is required to be put into use in high-altitude areas in China. Statistics shows that the plateau area with the altitude of more than 2000m accounts for 33 percent of the territorial area, and the area with the altitude of more than 1000m reaches 58 percent. The power industry is the leading industry, and in high altitude environment, a large amount of complete sets of switch equipment is necessarily required.
The existing common plants are designed according to the standard of elevation 1000m (less than or equal to). When the altitude increases, the air density decreases, causing a decrease in the cooling effect of the air medium, deterioration in the heat dissipation condition, and a decrease in the insulation strength. In the range of an altitude of 5000m, the height of each liter is 1000m, the average air pressure is reduced by 7.7 to 10.5kPa, the temperature rise is increased by 3 to 10 percent, and the external insulation strength is reduced by 8 to 13 percent. With the reduction of air pressure, the breakdown voltage is also reduced, and destructive discharge accidents such as insulation breakdown or flashover are easy to occur. The operation function of the product is directly influenced, large-area power failure is caused, and the stability of a power supply system is damaged.
In order to ensure that the product has enough breakdown resistance when used in a plateau environment, the electrical clearance must be increased and corresponding treatment measures must be taken.
