Digital Thermometer , Top Oil Temperature Gauge , Accessories for Oil - Immersed Transformer




The power transformer is an essential equipment in transmission and distribution system. Its failurerate is
closely related with its working temperature. An increase of temperature by 6℃ will double the aging speed of the transformer and decrease its operating life by half. With the aid of temperature measuring and control device, proper use of the transformer and immediate switch to the cooling device could avoid or decrease faults caused by high temperature of the transformer, thereby, prolong the operating life of the transformer.


Specially designed for measuring and controlling oil temperature in the top layer of the transformer, transformer oil surface thermometer of BWY(WTYK)series possesses favorable protective performance and can be used under outdoor conditions for a long term .Three sets of adjustable temperature switches are installed inside the meter , respectively for start-up of multiple sets of cooling system, over-temperature alarm and so on. Meanwhile , it could transfer the temperature signal to the remote computer system and make it real to synchronously display and control the transformer temperature.


Operating  Principles


The thermometer is mainly composed of spring elements, a capillary and thermo-bulb. Temperature sensing medium fills in the sealing system composed by these three parts. With the change of temperature, the volume of  temperature sensing medium in the temperature components will change accordingly. The capillary will transfer the volume increase amount to the spring elements inside the meter, which will lead to a corresponding displacement.
The magnified displacement will drive the indicating needle to indicate the temperature change; meanwhile, it switches on sensitive temperature switch to start up the corresponding cooling system,in order to control temperature increase of the transformer.


Transformer oil surface thermometer of BWY (WTYK) series adopts composite sensing technology and can synchronously display and control the oil temperature at the top layer of the transformer by means of remote transferring of Pt100 platinum resistance signal from thermo-bulb to the secondary meter in the control room.
