摘　　要：在三绕组电力变压器总损耗的一般表达式的基础上,引入了三绕组电力变压器等效负载损耗的概念,使三圈变压器总损耗的表达式与双圈变压器总损耗的表达式形式上相同,并且推导出了三圈变压器经济负荷功率、经济负荷率、经济运行效率的计算公式。以一台容量比为100/100/50的110kV三绕组电力变压器为实际算例说明了上述公式的实际用法。Based on the general expressions of the three-winding transformer total loss, this paper draws-in the concept of equivalent load loss of the three-winding transformer to enable the three-winding transformer total loss to have the same expressions as two winding transformers, furthermore to derive the calculation formula of economic load power, economic load rate, efficiency of economic operations of the three-winding transformer.It explains the practice usage of the formula above-mentioned with a capacity ratio 100/100/50 of 110kV three-winding transformer as a practice calculation example.

关 键 词：三绕组电力变压器 等效负载损耗 经济负荷功率 经济负荷率 经济运行效率
