110 kV户内变电站电气设备选型研究

Study on Electrical Equipment Selection of 110 kV Indoor Substation

随着城市110 kV变电站逐步向户内变电站的建设型式转变,电气设备选择研究对户内变电站优化设计意义重大。通过对主要电气设备型式、关键参数的合理选择,以提高变电站主要设备的使用寿命、经济性等主要技术性能,并对主变和110 kV GIS布置的关键尺寸进行了研究,以指导户内变电站的配电装置布置。

With the gradual transformation of urban 110 kV substation to indoor substation,the selection of electrical equipment is of great significance to the optimal design of indoor substation.Through the reasonable selection of main electrical equipment types and key parameters,the service life,economy and other main technical performance of main equipment in substation can be improved.The key dimensions of main transformer and 110 kV GIS layout are studied to guide the distribution device layout of indoor substation.
