Description

technical field [0001] The invention relates to the technical field of temperature measurement of transformer windings, 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 the AC voltage. Its main components are the primary coil, the secondary coil and the iron core (or magnetic core). [0003] During the use of the transformer, when an overload occurs, the transformer usually bears the brunt. Therefore, it is very important to monitor the thermoelectricity of the transformer winding, 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...
