中小型电力变压器经济寿命分析

The Economical Life Analysis of the Small and Middle-Sized Power Transformers

本文介绍了中小型电力变压器经济寿命的概念.在损耗费、维护费与可靠性价值评估的基础上,建立了经济寿命数学模型,算出了我国不同标准的中小型电力变压器的经济寿命,并进行了分析.

The conception of economical life is introduced for the small and middle-sized power transformers (SMSPT). Based on the evaluation of the loss and maintennace costs as well as the reliability worth,a mathematical model is developed for determining the economical life of the SMSPT. The real economieal lifes of the various SMSPT made according to the different standards of China are obtained and analysed.
