摘　　要：节能降耗是我国当前大力推进社会经济效益提高的重要工作之一,而供电系统中老旧高能耗配电变压器的使用是导致电网损耗的主要原因,因此需对其进行更新换代。本文采用总拥有成本(TOC)法进行了锡矿山闪星锑业有限责任公司南区变压站双电源供电系统中配电变压器更换经济效益的计算和评估,通过更换前S3型变压器及更换后S7型(1#和2#主变压器)和S11型(3#主变压器)经济效益的对比,得出S7型和S11型年节电费用分别为889772和1410237元,其中S11型变压器全年电费减低高达48%。Energy saving is one of the most important work at present in our country to vigorously promote the increasing social and economic benefits, and the use of power supply system in old＇.high energy consumption distribution transformer is the main cause of the loss of power grid, therefore it needs to be updated. The total cost of ovcnersbip （TOC） calculation and evaluation of distribution transformer replacement of the economic benefits of the double power supply system of tin ore mining bureau in the south station, by replacing the front S3 type transformer and replacement type S7 （1# and 2# transformer） and S11 type （3# main transformer） comparative economic benefit S7 type andS11 type, the annual saving costs were 889772 and 1410237 yuan, the annual reduction ofS11 type transformer electricity up to 48%.
