高压直流接触器寿命预测模型的研究
Research on Life Prediction Models of HVDC Contactors
摘要
Abstract
Higher reliability and longer service life have been the development directions for high voltage DC(HVDC)contactors.An electrical endurance test of an HVDC contactor is carried out.The degradation trends of featured parameters such as pick-up time,release time and arcing time are analyzed.In addition,according to the degradation and failure mechanisms of the contactor,the lifespan prediction models based on the function fitting and autoregression are established using the release time as the featured parameter.By comparing the prediction results,it is concluded that the lifespan prediction model based on autoregression has the best prediction accuracy.关键词
