摘要
针对750kV变电站的750kV导线采用2×JLHN58K-1600选型方案时电晕效应裕度较小,通过对2×JLHN58K-1600、4×LGKK-600和4×LGJ-800/100共3种导线选型方案的载流量、热稳定性、无线电干扰值、可听噪声的A计权声级、经济性和安装复杂性进行比较分析,给出750 kV变电站导线选型方案的推荐意见。
The conductor type-selecting scheme of 2×JLHN58K-1600 is widely applied in the 750 kV substation, but the corona effect of this type-selecting scheme is not good enough. Based on the comparison and analysis on the carrying capacity, the thermal stability, the radio interference value, the A-weighted sound level of audible noise, economical efficiency and installation complexity of three kinds of conductor type-selecting schemes-2×JLHN58K-1600, 4×LGKK-600 and 4×LGJ-800/100, recommendations of the conductor type-selecting scheme in the 750 kV substation are proposed.
