Design of Temperature Monitoring System for Oil-immersed Power Ransformers Based on MCU
With the expansion of electric capacity and largescale extension of power grid,electric equipment is playing a significant role in modern life. At present,the technology of condition monitoring and fault diagnosing of power transformer has been made some improvement,yet its real-time performance and reliability still cant meet the requirement of safe production. Due to different thermal effects led by the natural or factitious fault,its temperature of oil-immersed power transformers is easy to change abnormally. An on-line measuring and controlling system based on MCU is discussed in this paper. In order to satisfy the requirement of state monitoring and fault diagnosis of power transformer on real-time and reliability,a kind of intelligent on-line monitoring instrument is designed. Each of its part is explained in this paper,including temperature signal collecting and data processing system. The simulation result showed the designed system was good in its real-time,reliability and running cost. Therefore,the designed state monitoring system for temperature and fault diagnosis of power transformer can be widely used in engineering and is expected to bring a bright future.
