摘　　要：针对高海拔地区对电力系统安全距离的影响进行了深入的多因素分析。首先探讨了海拔升高导致的大气稀薄现象,进而引发的空气绝缘性能下降问题,这增加了电器设备间的电弧和火灾风险。同时,详细讨论了电气间隙与海拔之间的关系,特别是在电压等级选择上的重要影响。随着海拔的升高,空气介质的击穿电压降低,因此在高海拔地区,电气间隙需要更长的距离来保证设备的安全运行。还构建了一套基于多因素分析的复杂电力系统安全风险评估体系,以提高电力系统的安全性和稳定性。This study provides an in-depth multifactorial analysis of the impact of high altitude on the safety distances of power systems.Firstly,the phenomenon of atmospheric thinning due to increased altitude is explored,which in turn leads to the problem of reduced air insulation,which increases the risk of arcing and fire between electrical equipment.At the same time,the article discusses in detail the relationship between electrical clearances and altitude,in particular the important influence on the choice of voltage level.As the altitude increases,the breakdown voltage of the air medium decreases,and therefore,at high altitudes,electrical gaps require greater distances to ensure the safe operation of equipment.This study also constructs a complex power system security risk assessment system based on multi-factor analysis to improve the security and stability of the power system.
