Description

technical field [0001] The invention relates to an optical fiber temperature measurement technology, in particular to a temperature measurement optical fiber transfer module and a transformer with a temperature measurement optical fiber transfer module. Background technique [0002] Oil-immersed transformer is the key equipment of power distribution system. Oil-immersed transformers work in a high-voltage, high-current, and strong magnetic field environment for a long time, and will continue to generate heat during operation. For every 6°C increase in transformer temperature, the aging speed of the transformer doubles and the working life is halved. The safe operation and service life of oil-immersed transformers depend on the safety and reliability of windings, so accurate measurement of transformer winding temperature is particularly important for transformer service life. [0003] For oil-immersed transformers, the optical fiber temperature measurement method is used. W...
