Description

technical field [0001] The invention relates to the technical field of transformer winding temperature measurement, in particular to a fluorescent optical fiber temperature measurement system and method based on wireless sensing. Background technique [0002] Transformer refers to a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are primary coil, secondary coil and iron core (or magnetic core). [0003] During the use of transformers, when an overload occurs, the transformer will usually bear the brunt. Therefore, it is very important to monitor the thermal power of the transformer windings, which can protect the transformer from damage or even excessive use. [0004] At present, the conventional method is to simulate or calculate the temperature value, but it cannot be accurately measured. Therefore, it is urgent to provide a system or method capable of measuring the actual temperature value of the winding to solve this...
