常规户外220 kV和110 kV GIS设备出线一般采用A, B, C三相水平排列方式,构架采用人字门型构架一字排开,受出线门架宽度的限制,变电站出线侧宽度并未因采用GIS设备而减小。为此,提出了双飞蜓式垂直出线方式,采用独立钢管杆双回垂直架空出线,构架简单、出线方便,将大幅减少变电站占地面积,提高土地利用率。

Horizontal arrangement of phases A, B and C is generally adopted in outlet of outdoor 220 kV and 110 kV GIS equipment, in which miter gates of frameworks are lined up. Due to width limit of outlet portal, the width of substation outlet side is not reduced by GIS equipment adopted. Therefore, vertical double-drag-onfly outlet is adopted and overhead vertical double-circuit outlet on independent steel pole is employed, which is characterized by its simple framework, convenient outlet and can reduce floor space of substation and hence improve land utilization rate.
