| Abstract: | A temperature online monitoring system used to monitor temperature of switch cabinet bus and fixed contact was designed based on fiber bragg grating(FBG).FBG temperature sensor adopted non-strain-sensitive packaging,avoiding the influence of strain of sensor on measurement results in the process of installing and testing,and improving the accuracy and reliability of monitoring temperature performance as naked FBG.The monitoring system had been working for more than one year in good condition. |
