The dry-type transformers are fully functional, all parts are concentrated in the dry-type transformers, therefore, it can be used in schools, residential, shopping malls, factories and other places. The current hot weather, there are many users are reflected, dry-type transformer internal temperature increased abnormally.
In the same circumstances of dry-type transformers load, the ambient temperature, the internal temperature continues to rise, which proves that there is a failure inside, should deal with in a timely manner.
The cause of the internal temperature anomalies of dry-type transformers is usually the following.
1. the transformer short circuit between the turn or the layers.
2. transformer core short circuit locally.
3. due to leakage of magnetic or eddy current caused fuel tanks, boxes heat.
4. long-term overload operation.
5.Heat dissipation conditions worsen
Finally, dry-type transformers found exceptional temperature, should first identify the cause, and then take the appropriate measures to be ruled out, make the temperature down. If the dry transformer is caused by internal failure, should stop running, for maintenance.
