Is it normal for the transformer to smoke?

1. Under normal circumstances, the smoke from the transformer can be ignored

During the normal operation of the transformer, the small amount of smoke produced is negligible. This is because when the transformer is working, the transformer oil will decompose and produce gas, part of which is light gas, so it will roll up and produce a small amount of smoke, but this smoke is harmless and will not affect the service life of the transformer .

2. Under abnormal circumstances, the smoke of the transformer needs to be paid attention to

（1）. The transformer is overheated, causing smoke

When the transformer is working, due to the effect of current, the inside of the transformer will continuously generate heat, but the inside of the transformer will also dissipate the heat through oil circulation. If the oil circulation is not smooth, or there is a problem with the quality of the internal components of the transformer, it will cause the internal temperature of the transformer to rise, and eventually cause smoke. At this time, it is necessary to check the oil circulation system, or replace the faulty parts inside the transformer.

（2）. Problems with transformer design or selection

If the design or selection of the transformer is improper, it will also cause the transformer to generate too much heat when it is working, and eventually produce smoke. In this case, the transformer needs to be redesigned or adjusted, or a suitable transformer should be replaced.

3. How to deal with transformer smoke

If the transformer smokes, it needs to be shut down in time. First of all, it should be checked whether the heat dissipation system inside the transformer is normal and whether there is any abnormal electrical connection. Second, electrical components or other parts may need to be replaced. If the above methods do not solve the problem, the entire transformer needs to be replaced.

In short, the normal or abnormal phenomenon of transformer smoke is related to many factors. Generally, small amounts of smoke are negligible. However, if there is too much smoke or an abnormal situation occurs, it must be dealt with in time to ensure the normal operation of the equipment.
