Dry type transformer is an important electrical equipment and an important electrical appliance. Its temperature is an important external factor affecting the operation of dry type transformer. For common dry type transformer temperature also has a variety of related regulations, common temperature of dry type transformer has a strict requirements, should be constantly to improve the detection of the temperature of the dry type transformer, dry type transformer temperature aspects should improve the level of detection, and realize the safety and performance of dry type transformer. For dry transformer temperature has a strict regulation, its temperature is generally measured with a thermometer.
Dry transformer temperature in operation refers to the upper oil temperature of dry transformer.
Provisions on oil temperature of middle and upper layers in dry transformer operation:
1. The upper oil temperature of oil-immersed self-cooled or air-cooled dry-type transformer generally does not exceed 85 ° C, the highest does not exceed 95 ° C, and the temperature rise does not exceed 55 ° C;
2. The upper oil temperature of the forced oil circulation air-cooled dry transformer shall not exceed 65℃ and the highest shall not exceed 75℃;
3. The coil temperature of low-voltage dry-type transformer for factory use shall not exceed 155℃ and the maximum shall not exceed 170℃.

The above is the common dry transformer in the operation of the main temperature related characteristics for your reference, for the dry transformer temperature you have any other questions please consult our manufacturer or contact our technical personnel to understand it in detail!
