摘要

干式空心电抗器为电感线圈

是电力系统中的关键元件

其自身温升及支撑金具的温升对安全运行至关重要。随着电抗器容量的增大

电抗器温升测量及仿真技术也变得越来越重要。本文主要是从电抗器的结构、磁场、温度场方面进行研究。介绍了电抗器的温升仿真计算方法及结果

从理论计算方面找出电抗器线圈本体的最高温升点

以及支撑金具材质的变化对温升的影响。通过对电抗器的仿真计算

得出如下结论:在稳态运行时

电抗器绕组的温度分布为上高下低

热点位置在中间层包封的上端部。在强磁场中

铝合金的发热要高于不锈钢材质

推荐使用不锈钢材质作为电抗器支撑材料。

Abstract

The dry-type air core reactor is an inductor coil

is a key component in the power system and its own temperature rise and the temperature rise of the supporting fittings are essential for safe operation.With the increase of the reactor capacity

the temperature rise measurement of the reactor and simulation technology is more and more important. In this paper

the study is made from such aspects as the structure of reactor

magnetic field and temperature field. The simulation calculation method and result of the temperature rise of the reactor are introduced. The highest temperature rise point of the reactor coil and the influence of material of the support fittings on the temperature are found from the theoretical calculation. It is concluded throughout simulation calculation of reactor that at steady operation

the heating of aluminum alloy is higher than that of stainless steel and the latter is recommended to be used as the support material of the reactor.
