Cause Analysis of Temperature Variation during Operation of Transformer

The main cause of the overall temperature change in the single phase step voltage regulators operation is the loss of the transformer and the influence of the ambient air temperature. Transformer losses include transformer no-load loss and load loss, the no-load loss in the transformer has been put into operation after the load loss with the transformer load with the size of the change, the greater the single pole transformer load, the more loss, the transformer The higher the temperature rise; the greater the load change, the greater the temperature change of the transformer. In addition from the national electricity load market changes throughout the year the actual situation, the more cold or hot weather, electricity load growth faster, the higher the temperature rise of the transformer; even on the same day, due to changes in day and night temperature and Load peak-valley difference of the superposition of changes, but also caused a significant change in the temperature of the transformer a major factor. As a result of these various factors, resulting in transformer temperature is changing, thus affecting the long-term safe operation of transformer and service life.
