The dry-type transformer overheats

Sometimes we will find that the dry-type transformer is very hot during operation, which is because the dry-type transformer is very hot, and it is necessary to observe the temperature of the dry-type transformer in detail at this time. There are many reasons why the temperature of Dry-type single phase transformer is too high, and we have to take a closer look at the situation and reasons for excessive temperature of Dry-type single phase transformer? Or and dry-type transformer manufacturers of Wankang to understand in detail.

The top oil temperature of the national standard dry-type transformer is generally adjusted at 85 °C, if it exceeds 85 °C, the reasons should be analyzed: 1. If it is because the room temperature is too high, the load is too heavy, etc. slowly rises, it can continue to operate beyond 85 °C, but it cannot exceed 95 °C (at this time, the core or winding of the dry-type transformer is 105 °C, which will seriously damage the insulation, shorten the service life or burn the dry-type transformer); 2. When the dry-type transformer exceeds 85 °C, the difference between the oil temperature and the room temperature at the top of the dry-type transformer cannot exceed 55 °C, if it is exceeded, it may be a serious overload, too low voltage, too large current, internal failure, etc., and continued operation will seriously damage the insulation, shorten the service life or burn the dry-type transformer.

The above is the main cause of overheating of common Dry-type single phase transformer, when the temperature of Dry-type single phase transformer is too high, the reasons should be analyzed in accordance with the above regulations, and then solved.
