摘　　要：本文以某运行近25年的老旧变电站500 k V电力变压器为实例研究了变压器设备的全生命周期成本为实例,基于某该变电站运行多年以来的运行数据,对该站主变的材料、性能、运行工况进行分析,结合20年前生产制造的工艺、水平和技术能力,考虑包括初始投资成本、运行成本、检修维护成本、故障成本以及退役处置成本,对某变电站500 k V主变压器的全寿命周期成本进行综合评估,并通过电力变压器对合资品牌以及国产优质品牌2个质量水平的产品进行分析比较,得出了设备购置成本对LCC的控制起到主导作用,在检修维护成本、故障成本以及退役处置成本占比不大的情况下,合资品牌产品较高的设备购置费用不利于成本的控制,国产优质品牌产品的全寿命周期成本相对更优的结论。In this paper,the whole life cycle cost of transformer equipment is studied by an example of 500 k V power transformer in an old transformer substation that has been running for nearly 25 years,based on the data of the substation operation for many years,the station of the main transformer materials,performance,operation condition is analyzed,combining with the manufacturing process of 20 years ago,level and technical ability,consider including the initial investment cost,operation cost and maintenance cost,fault and decommissioning disposal cost,The total life cycle cost of 500 k V main transformer in a substation is evaluated comprehensively,Through the analysis and comparison of the two quality level products of the joint venture brand and the domestic high-quality brand by the power transformer,it is concluded that the purchase cost of the equipment plays a leading role in the control of LCC,In the case that the cost of overhaul and maintenance,the cost of failure and the cost of decommission-disposal are relatively small,the purchase cost of the high equipment of the joint venture brand is not conducive to the control of cost,The whole life cycle cost of domestic high quality brand products is relatively superior.
