Aling tagagawa ang pinakamahusay para sa pag-install ng fluorescent fiber optic temperature sensors at monitoring system para sa mga windings ng transpormer

Ang 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 sistema ng pagsukat ng temperatura ng optical fiber 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 pagsukat ng temperatura ng fiber optic 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, at temperatura sa ilalim ng langis, 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 pagsukat ng temperatura ng fluorescence fiber optic 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. Bilang karagdagan, through long-term operation, it has been proven that the monitoring system is safe, maaasahan, at matatag. It can replace winding thermometers and oil temperature gauges, and can also replace manual inspections. Kasabay nito, 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 ng Fiber Optic Temperature Measurement System for Oil Immersed Transformer of Main Transformer

1) Teknolohiya sa pagsukat ng temperatura ng fiber optic, 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 pagsukat ng temperatura, 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. Samakatuwid, 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.
