The effect principle of transformer oil temperature controller

Transformer oil temperature controller is mainly for measurement and control of large power transformer oil temperature, but also used in other temperature detection and control of the equipment. Transformer oil temperature controller has good protection performance, can work for a long time in the outdoor conditions, instrument internal with two or three sets of large capacity temperature control switch, can be respectively used in transformer cooling system startup, shutdown and alarm signal, and can transmit the temperature signal is far to the control center, synchronous display transformer oil temperature.

the oil level of transformer temperature controller application 'heat bilges cold shrink' principle, in the airtight system full of heat medium. When the thermal head into the material being measured, and the temperature of the material changes, due to the heat bilges cold shrink, filling medium thermal head inside the filling medium volume changes have taken place, the volume change by capillary to header internal elastic element, make the corresponding displacement, the displacement after amplification mechanism amplification, can directly indicate the temperature of the material being tested.

the oil level of transformer temperature controller can be respectively used in transformer cooling system startup, shut down and signal alarm and overtemperature tripping, etc. In order to make room for the real time temperature signal, the oil level of transformer temperature controller can form a complete set of temperature display instrument and synchronous display transformer oil temperature, and can be with the computer network, so as to achieve control transformer oil temperature, alarm, tripping, etc.
