Problems solved by technology

The bursting of disc-shaped glass insulators by the environment will also cause damage to the surrounding electrical components
[0003] Existing insulators, whether they are porcelain insulators, disc-shaped glass insulators, etc., will burst if they are affected by the external environment to a certain extent. After the burst, the fragments will fall on the electrical equipment and cause damage to the surrounding electrical components. It is necessary to replace the insulator with a new one. Due to the large damage area, it is more difficult to repair the substation, and the social impact is huge.

Description

technical field [0001] The invention belongs to the technical field of insulators, and relates to an explosion-proof insulating paint for insulators. The explosion-proof insulating paint of the invention is coated on the surface of an insulator, which can reduce damage to surrounding electrical components after the insulator explodes. Background technique [0002] There are a lot of electrical equipment in the substation, such as air-core insulators, porcelain insulators, etc. These insulator bushings are composed of many instrument lines. Once an accident occurs, they will explode. Not only the insulators will explode, but the surrounding electrical equipment and instruments will also be damaged. damaged. The bursting of disc-shaped glass insulators by the environment will also cause damage to the surrounding electrical components. [0003] Existing insulators, whether they are porcelain insulators, disc-shaped glass insulators, etc., will burst if they are affected by the...
