Design and Implementation of an On-line Life Prediction System for TWT

Starting from the analysis of the field application of Traveling wave tube and aiming at the power attenuation problem caused by the aging of Traveling wave tube, this paper analyses the influence of power attenuation on the system performance and introduces the definition of service life of Traveling wave tube. An online residual life prediction method based on power coupling measurement and data fitting is presented. An online monitoring system of Traveling wave tube is developed by using this method. The system can be compared. Accurate prediction of residual life can provide scientific basis for information equipment maintenance.
