Oil level winding thermometer,Also known as winding temperature controller, winding temperature indicating controller,
Product introduction of temperature controller:
It is mainly composed of elastic element, sensing tube, temperature sensing component, electric heating element, integrated converter and digital display instrument. The temperature packet of the transformer winding thermometer is inserted into the oil hole on the top of the transformer oil tank. When the transformer load is zero, the reading of the winding thermometer is the temperature of the transformer oil; When the transformer is loaded, the current directly proportional to the load taken out through the transformer current transformer flows through the electric heating element embedded in the corrugated pipe after being adjusted by the converter, The displacement of the elastic element increases. Therefore, after the transformer is loaded, the displacement of the elastic element is determined by the top oil of the transformer and the load current of the transformer. The temperature indicated by the transformer winding thermometer 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 measured transformer coil.
