During the use of the transformer, the insulation parts are often aging due to some physical or chemical factors. Then what factors are the main causes of the aging problem of the transformer insulation parts?

1. The transformer is a power device, which is filled with a large amount of electricity. Partial discharge is easy to produce ozone. Ozone is a very oxidizing substance, which can easily cause the insulation material to be oxidized and cracked by ozone, which is electrical aging.

2.In addition to electrical aging, there is also thermal aging. When the transformer is running, it is easy to generate a lot of heat inside, so that the polymer insulation material is thermally degraded, and low-molecular-weight materials are generated or escaped. This is common heat. Aging and thermal aging will greatly reduce the insulation and mechanical properties of insulating materials.

3. There is also a kind of aging called environmental aging, which refers to the polluting chemical reaction caused by insulating materials under the action of light, oxygen, radiation, acid and alkali and other factors, and the most important factor is the ultraviolet rays in the sun.

Through the above analysis, everyone should be able to see that the aging problem of transformer insulation is inevitable. What we can do is to check the transformer regularly, and replace the transformer insulation parts in advance, so as to avoid some power failures.
