摘要

准确计算换流变压器的负载损耗

对换流变压器的稳定运行

具有十分重要的意义。文中分析了目前常用的几种换流变压器负载损耗计算方法

并对其进行简单评述。在此基础上对各方法建立的假设前提进行了分析论证。分析表明:结构件杂散损耗与电流的平方成正比的关系成立

但与频率的0.8次方成正比的关系需进行进一步校核

否则会给负载损耗计算带来误差

建议将导磁材料和非导磁材料分开进行研究。

Abstract

It is significant to calculate the load loss of the converter transformer for operating steadily. In this paper

several methods for calculating the load loss of the converter transformer have been compared and discussed. Then the assumed conditions for methods are analysed. It is indicated that the stray loss in structural parts is proportional to the square of the current approximately

but it is necessary to test whether it follows the frequency with the exponent 0.8

otherwise the method will cause the error for the load loss calculation. It is advised to analysis the non-magnetic material and magnetic material separately.
