Product data sheet
Bwr-04y transformer winding temperature controller is a special instrument designed for measuring and controlling the top oil temperature of large oil-immersed transformer and the winding temperature of transformer. It adopts "thermal simulation" method to measure the winding hot spot temperature indirectly and adopts the principle of "additional temperature rise".
The winding temperature is measured indirectly by the thermal simulation measurement method, and the output current value is adjusted by the rated current output of the transformer through the converter, so that the heating element in the thermostat generates the displacement, which is superposed in the indicating mechanism in the thermostat to produce the corresponding angular displacement, thus indicating the sum of the top oil temperature of the transformer and the winding temperature. At the same time, the control switch in the temperature controller is driven to output the switch signal, drive the cooling system, control the top oil temperature of the transformer and the temperature rise of the transformer winding.
Built-in precision potentiometer, can output resistance signal proportional to the range, and BWD-1Z02B transformer with electronic thermostat, can be used for remote display, and can be used for computer systems.
The product has good protective properties and can work normally in outdoor conditions all weather
