摘要
本文提出了在变压器设计时应当考虑其运行时的累加能量损耗的观点,推导出累加能量损耗的多种表达式,建立了同时包括制造费用和运行损耗费用的变压器设计用目标函数。同时,对优化设计的方法也进行了讨论,并在此基础上,完成了50kVA 配电变压器的优化设计。
A new idea,the cumulative energy loss is proposed and taken into account for the design of distribution transformers.The objective function considering both the costs of materials and cumulative energy loss of a transformer is presented.The method used for the optimum design with microcomputer is also discussed and a well-designed 50kVA,10/0.4kV three-phase distribution trans- former is obtained by means of present method.
