Abstract: The characteristic that the distributed optical fiber in temperature test technology itself is both a temperature sensor and a temperature transmission media is especially adaptable for temperature on-line monitoring of high-voltage equipment, such as high-voltage cable etc. Introduction was made to a kind of design method of distributed optical fiber temperature on-line monitoring system. The system included temperature test optical fiber, photoelectricity monitoring and signal processing circuits and main machine etc hardware facility. The on-line monitoring software realized monitoring, constant temperature alarming, temperature rising alarming and characteristics displaying of overheat partial cable etc functions, which achieves on-line monitoring for high-voltage cable etc high-voltage electrical equipment.
Key words: distributed optical fiber; temperature; on-line monitoring
