Application of Fiber Grating in Power Equipment Temperature Alarm
In view of the power equipment temperature excessive to lead the electric power accident, takes the fiber Bragg grating as the transmission and sensing media of the signal, through fitting curve of the actual temperature, use the fiber Fabry-Perot (F-P) filter demodulate the Bragg wavelength of the fiber grating, chooses higher reliability light emitter diode as the photosource, through the single chip microcomputer and the double CPU of the DSP realizes data processing and control, has realized the power equipment temperature alarm system. This system has the strong anti-interference ability, the high reliability, the simple mounting, the convenient maintenance, the remote transmitting signal and so on the characteristic, is suitable with long-distance temperature monitoring and alarm of the power equipment.
