| 摘 要： | 为了合理选择220 kV银盘水电站送出线路重冰区导线,先从系统输送容量入手,确定输电线路导线分裂根数、间距及截面,再从重冰区输电线路设计的特点出发,通过对常见的3种钢芯铝绞线(GB/T1179—1999)的机械强度及过载能力、铝部应力、弧垂特性、耐振性能、荷载条件以及经济性等方面进行比较分析,重点分析了不同钢芯截面的导线在重冰区的技术经济特性,最终推荐银盘水电站220 kV送出线路20 mm冰区段导线选用2×LGJ-630/55,通过较为系统的导线选型分析,为重冰区高压架空输电线路导线选型、校核探讨了一套方法。

| Abstract: | The line conductor selection method for 220 kV Yinzhang transmission line in heavy icing area is introduced.The line conductor split number,distance and section is determined by system transmission capacity.According to transmission line design characteristics in heavy icing area,three types of aluminum conductor steel reinforced(GB/T 1179-1999) are compared in different aspects including mechanical strength,overload capacity,aluminum stress,sag characteristic,vibration resistance performance,loading conditions and economy characteristics,especially performance of different steel conductor size in heavy icing area.The 2 × LGJ-630/55 conductor is selected in 20 mm icing area.The systematic analysis of conductor selection provides method for overhead transmission line conductor selection and validation in heavy icing area. |
