On-line temperature monitoring system of HV electric apparatus based on optical-fiber fluorescence

It has been paid extensive attention to realize temperature on-line real-time monitoring of (electrical) facilities.For the specialty of some temperature measurement situation,traditional sensor hard to utilized.The optical fiber fluorescence sensors play important role in such specific circumstance because of their properties of anti-electromagnetic disturbance?smaller volume?being able to bear higher voltage and corruption.This paper presents the application status of temperature monitoring system of HV electric (apparatus),and introduces two overseas temperature monitoring system with optical-fiber.A newly-designed on-line multi-channel temperature monitoring system based on optical-fiber fluorescent is emphasized.In (addition),the basic principle of this system is analyzed in detail,and the entire system configuration is (introduced).Finally,technical targets are given by the experimental results.
