Application of 9-channel fluorescent fiber optic temperature measurement system for temperature monitoring of oil immersed transformer winding

The fluorescent fiber optic temperature measurement system is designed specifically for power applications and is very suitable for measuring the temperature of hot spots in transformer windings. It is a new type of transformer internal temperature monitoring device that can directly, real-time, and accurately measure the temperature of hot spots such as windings, and can achieve comprehensive monitoring of the transformer's internal environment. In addition to having a wide temperature measurement range and accurate and reliable temperature measurement performance, it also has excellent anti EMI/RFI (electromagnetic interference/radio frequency interference) characteristics, high-voltage insulation, and anti-interference performance.

With the development of transformers towards ultra-high voltage, large capacity, and intelligence, using fiber optic temperature measurement systems to directly measure the hot spot temperature of transformer windings has gradually become an important development direction to ensure their safe and reliable operation. From multiple aspects such as temperature measurement principle, reliability, applicability, and testing, it is concluded that fluorescence fiber optic temperature measurement technology is an excellent temperature measurement method. The selection scheme of main transformer fiber optic winding temperature measurement methods under different capacities and voltage levels is provided, providing practical cases for the development and application of direct temperature measurement technology for main transformer windings.

The 9-channel fluorescent fiber optic temperature measurement system is used for temperature monitoring of oil immersed transformer windings, with stable operation and accurate actual temperature monitoring. Please contact us for specific installation plans and prices.

The transformer fiber optic winding temperature measurement device adopts a fluorescent fiber optic temperature sensor, which can directly measure the hot spot temperature inside the transformer winding. The sensor design and communication system do not interfere with the strong electromagnetic field inside the transformer, and can be directly installed on the transformer winding. It has the characteristics of direct, online, real-time, and accurate measurement of the hot spot temperature of the winding, and can achieve real-time and accurate monitoring of the "hot spot" temperature during dynamic load operation. Providing critical temperature data without affecting transformer operation, capable of real-time adjustment of equipment load and cooler output based on temperature, maintaining maximum equipment output capacity and increasing equipment service life.
