Reliability centered maintenance (RCM) is well known for its widely application in various manufacturing industries, but the study on insulating switches of substation is still blank. In this paper, based on RCM evaluation, fault tree is built according to substation fault data, so as to establish fault assessment model of insulating switches. Corresponding fault and maintenance, RCM evaluation model is set up to assess substation maintenance scheme. After combining with actual data from all substations, a series of calculation is implemented, which lead to improving suggestions. Eventually, optimal reliability and economical efficiency is achieved.
