高海拔盐湖地区箱式变电站高压侧进线方式改进

Improvement of High Voltage Side Entry Mode of Box Type Substation in High-altitude Salt Lake Area

针对高海拔盐湖地区箱式变电站输送中容易受大风、雷击、鸟害、覆冰以及外力破坏影响,本文首先详细分析了大风、雷击、鸟害、覆冰以及外力破坏对高海拔盐湖地区输电的影响,并根据已有标准对高海拔盐湖地区箱式变电站高压侧进线方式进行了改进,结果表明设计的箱式变电站能够提高输电稳定性。

For high altitude salt lake area box type substation transportation is easy to be affected by strong wind,lightning strike,bird damage,icing and external force damage.In this paper,the infl uence of strong wind,lightning strike,bird damage,icing and external force damage on transmission in high altitude salt lake area is analyzed in detail.Then according to the existing standards,the highvoltage side line mode of box substation in high altitude salt lake area is improved.The results show that the designed box substation can improve the transmission stability.
