Temperature Inspection Of Distribution Transformers

The operating temperature of a transformer is closely related to its lifespan. The transformer operates at a normal temperature below 95 ℃ and has a lifespan of 20 years; If operated at 110 ℃, the lifespan will be shortened to 7 years; If the temperature rises to 130 ℃ for operation, its lifespan will be shortened to 2 years; The transformer will be scrapped after continuous operation at a temperature of 170 ℃. If the temperature exceeds the allowable value of the transformer, the cause should be identified and countermeasures taken in a timely manner.
