The working principle of the TEMPERATURE TRANSFORMER WINDING THERMOMETER BWR-04JJ(TH) is as follows:

1. When the transformer load is zero, the reading of the winding thermometer is the temperature of the transformer oil.

2. When the transformer is loaded, the current proportional to the load taken out by the transformer current transformer flows through the electric heating element embedded in the bellows after adjustment by the converter.

3. The heat generated by the electric heating element increases the displacement of the elastic element. Therefore, after the transformer is loaded, the displacement of the elastic element is determined by the top oil temperature of the transformer and the transformer load current.

4. The temperature indicated by the transformer winding temperature is the sum of the transformer oil temperature and the temperature rise of the coil to the oil, reflecting the temperature of the hot part of the transformer coil under test.

TEMPERATURE TRANSFORMER WINDING THERMOMETER BWR-04JJ(TH) is widely used in various transformers, especially in unmanned power stations, high-voltage switchgear and other scenarios.
