摘要：As the core equipment of many construction electric fields, reasonable life management of power transformer plays an important role in ensuring the safety production and economic benefits of public and enterprises. Based on Lambert W function, the exact solution is obtained by calculating the annual apportioned total cost. The variable values that may have errors in the function model are deeply analyzed. Combined with the inherent characteristics of power transformer, the factors influencing the economic life in the results are analyzed. The reliability of this method is proved by an example. Compared with the traditional tabulation method, this method is convenient for further analysis of the influencing factors and changing rules of economic life. At the same time, this method can also be used in other equipment to study its economic life since the specific problems are analyzed. It has the value of popularization.
