摘　　要：对2007年全国220kV及以上电压等级13类输变电设施,特别是对影响变压器、断路器、架空线路3类主要输变电设施可靠性的计划停运、非计划停运的主要因素进行了分析比较。通过对近几年可靠性指标的分析比较,提出了影响可靠性因素的变化趋势,为未来几年提高输变电设施可靠性提供了有益的依据。The reliability of nation-wide 13 kinds of power transmission and transformation facilities with voltage of 220 kV and above was analyzed in 2007,especially the major factors of scheduled outage and forced outage for influencing reliability of 3 kinds of power transmission and transformation facilities,such as transformer,circuit breaker and overhead transmission line,were analyzed and compared. Through the analysis and comparison of reliability index for last few years,the change tendency of effects on reliability factors was put forward,which offered beneficial basis for improving reliability of power transmission and transformation facilities for the next few years.
