摘　　要：针对现有维修模式中存在的“维修不足”和“维修过度”等问题,提出了一种计及指标重要度的地铁供电设备健康状态分级评估方法。根据层次分析和模糊统计相结合的方法求解设备健康值,并将指标的重要度考虑在内,对设备所处的健康状态进行等级划分,最后以干式变压器为例进行实例分析。研究结果表明:利用本文提出的评估方法能够合理地表征地铁供电设备的健康状态,与实际情况符合,验证了方法的准确性及可行性。To address the problems of“insufficient maintenance”and“excessive maintenance”in existing maintenance modes,a health status grading evaluation method for subway power supply equipment that considers the importance of indicators is proposed.First,the equipment health value was solved according to a combination of an analytic hierarchy process and fuzzy statistics.The importance of the index was considered,and the health status of the equipment was graded.Finally,a dry-type transformer was considered for analysis.The results show that the obtained results can reasonably characterize the health status of the subway power supply equipment,which is consistent with the actual situation,and verify the accuracy and feasibility of the method.
