基于负载率和健康状态的高压XLPE电缆可靠性评估模型
Development of high voltage XLPE cable reliability assessment model based on load rate and health status
摘要
Abstract
For the voltage(HV) XLPE cable,its insulation hot spot temperature (IHST) was chosen as the key variable.Firstly,the load rate based aging failure model of XLPE was developed by employing the Weibull distribution and the Arrhenius reaction law.Next,a HV cable health index (HI) model based on fuzzy analytic hierarchy process (FAHP) was conducted by using its preventive tests,online inspection techniques,daily routine inspections and historical records.In order to better use the two models,the HI was introduced to the aging failure model,then,a comprehensive failure factor model that can reflect both the irreparable faults and repairable faults was proposed.Finally,a case study shows that the model can reflect the actual reliability level of HV cable,providing the theoretical basis for the maintenance departments to carry out the equipment maintenance and having a certain reference value.关键词
