Problems solved by technology

Due to the relatively large size of the 35kV metering transformer, and the limited space in the high-voltage chamber of the 35kV wind power combined transformer, it is generally difficult to arrange it; moreover, it is arranged outdoors, and the top cover of the high-voltage chamber is formed by bending a thin steel plate, which is difficult to install in winter in ice and snow weather. , the blades of the fan are covered with ice, and when the ice melts, ice cubes will fall and hit the top cover, causing damage to the top cover. At present, there is no technical solution that can effectively break down the impact force of the ice cubes to avoid damage to the top cover.
