Causes Of Abnormal Internal Temperature Of Dry-Type Transformers
Release Time：

The dry-type transformer has complete functions and all parts are concentrated inside the dry-type transformer. Therefore, its appearance is small and can be used in schools, communities, shopping malls, factories and other places. When the weather is hot, many users have reported to us that the internal temperature of dry-type transformers has risen abnormally.
The dry-type transformer has complete functions and all parts are concentrated inside the dry-type transformer. Therefore, its appearance is small and can be used in schools, communities, shopping malls, factories and other places. When the weather is hot, many users have reported to us that the internal temperature of dry-type transformers has risen abnormally. In response to this problem, we will give you the reasons for the increase in internal problems of dry-type transformers.
The internal temperature of the dry-type transformer continues to rise under the original conditions under the condition of constant load, heat dissipation, and ambient temperature, which proves that there is an internal fault, and it must be dealt with in time. The reasons for the abnormal internal temperature of the dry-type transformer are usually as follows.
1．Short circuit between transformer turns, layers and strands.
2．The transformer core is short-circuited locally.
3．The fuel tank and cover are heated due to magnetic flux leakage or eddy current.
4．Long-term overload operation and accident overload.
5．Deterioration of heat dissipation conditions, etc.
If the dry-type transformer has abnormal temperature during operation, the cause should be found out, and then corresponding measures should be taken to eliminate the temperature. If it is caused by the internal fault of the dry-type transformer, the operation should be stopped and repaired.
