节能型干式半芯并联电抗器在输电系统中的应用

Application of Energy Saving and Dry Type Half Core Shunt Reactor in Transmission System

介绍了干式半芯并联电抗器的技术、性能特点,如体积小、耗电低、噪声小、不受环境限制等。西安高压供电局北郊变电站扩建改造中选用了干式半芯并联电抗器。文章对干式半芯并联电抗器与同容量的干式空芯并联电抗器进行了分析比较,表明:前者的安装面积可节约1/5左右;能源利用率提高了约36%。因而这种电抗器的经济效益和社会效益是十分明显的。

The technology and performance characteristics of the dry type half core shunt reactor were introduced, such as less volume, lower consumable electricity, little noise and no environmental restriction. The retrofit and extension of north suburb substation in Xi 'an Power Supply Bureau adopted the dry type half core shunt reactor. The paper compared the dry type half core shunt reactor with the dry type air core shunt reactor in same capacity. The comparison shows that the installed area can be economized 1/5, and energy utilization rate be risen 36%. The social benefit and the economic benefits of this kind of reactor are obvious.
