摘　　要：常规户外330 kV GIS配电装置出线一般采用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,330 kV出线宽度受出线门型构架宽度的限制,并未因采用GIS设备而减少,没有充分发挥GIS设备布置的优势,这在高海拔地区表现尤甚。为此,提出在330 kV GIS配电装置中采用立体紧凑型出线方案,利用导线空间排列的方式满足电气距离,以达到压缩出线构架宽度的效果,节约占地面积,同时也节约GIS主母线长度,减少设备造价,与线路侧终端塔接线可更好地配合,经济效益和社会效益显著。Horizontal arrangement of phases A、B and C is generally adopted in outlet of outdoor 330 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-dragonflyoutlet is adopted and overhead vertical double-circuit outlet onindependent steel pole is employed,which is characterized by its simple framework,convenient outlet and can reduce floor space of substationand hence improve land utilization rate.
