In this paper, based on the theory of life cycle cost (LCC), the LCC of transformer was analyzed，and the life cycle cost calculation model of transformer was established. For calculating the cost of transformer loss, in order to make the final calculation results more accurate, the correction coefficient of electricity price is considered to improve the calculation model. Then, in order to reduce the loss of the transformer operation and save cost, the load rate of transformer is combined with efficiency to get the optimal load rate, so as to calculate the operating loss of transformer. Finally, these two improvement scheme were proved through the calculation and contrast analysis of examples.
