वही fiber optic temperature measurement system for monitoring the hot spot temperature of transformer windings has been widely used in thousands of transformers worldwide in recent years and has passed industrial design certification. There is already a lot of experience in applying fiber optic buried winding temperature measurement technology to transformer temperature monitoring abroad. The entire system mainly includes fiber optic temperature controllers, fiber optic probes, fuel tank wall penetrators, fuel tank wall junction plates, external extension fibers, and optional fuel tank wall protective covers.
FJINO has installed an optical fiber temperature measurement system for the intelligent main transformer of the transformer manufacturer and officially put it into operation. The main transformer winding hot spot fiber optic temperature measurement system includes data sampling and analysis alarm functions, and can be linked with the communication components of intelligent components. Adopting independently developed fiber optic temperature measurement controller, the installation location of fiber optic temperature measurement for the hot spot of the main transformer winding is determined based on operational requirements and the technical characteristics of the temperature measurement equipment, including top oil temperature, high voltage winding, medium voltage winding, and bottom oil temperature, covering all important areas of the main transformer, enabling real-time monitoring and diagnostic functions to be truly realized, thereby reducing the probability of damage to the main transformer winding and extending the service life of the main transformer.
The online temperature monitoring system for transformers using fluorescence fiber optic temperature measurement technology can monitor the temperature of various components inside the transformer in real time and accurately. As it is a direct contact measurement, it has more reference significance than theoretical calculations. इसके अलावा, through long-term operation, it has been proven that the monitoring system is safe, भरोसेमंद देखिए।, and stable. It can replace winding thermometers and oil temperature gauges, and can also replace manual inspections. एक ही समय में, by detecting temperature, the life loss of transformers can be evaluated, which has a good reference value for the health status and life assessment of transformers, providing an effective technical means for online temperature detection of transformers.
Function of Fiber Optic Temperature Measurement System for Oil Immersed Transformer of Main Transformer
1) Fiber optic temperature measurement technology, as a necessary monitoring technology for intelligent transformers, can not only provide early warning and fault analysis for transformers, but also enhance the transmission capacity of intelligent transformers;
(2) When arranging points for fiber optic temperature measurement, the distribution pattern of the hottest point of the coil should be considered to obtain better measurement points and ensure the accuracy of transformer hot spot temperature measurement;
(3) Intelligent transformers should determine corresponding technical parameters based on different regions and special technical requirements when applying fiber optic temperature measurement technology. Power transformers are the core equipment of power systems, and the hot spot temperature of windings affects the insulation life of transformers. इसलिए, it is necessary to monitor the hot spot temperature of transformer windings online. By comparing several methods for measuring the hot spot temperature of transformer windings, it was found that using fiber Bragg grating sensors to measure transformer windings not only measures the true temperature of the transformer winding, but also has high measurement accuracy and good system stability.
