高海拔地区电气设计中的海拔修正方法研究

Research on Elevation Correction Method in Electrical Design of High Altitude Area

基于海拔高度对电气设备的外绝缘性、安全距离等的较大影响,通过对现有相关规范、标准的对比和分析,结合电气设计经验,总结出高海拔地区输电线路和配电装置的电气外绝缘水平、电气安全距离以及绝缘子片数的修正方法,为电气设计提供参考。

Based on the great influence of altitude on the external insulation and safety distance of electrical equipment, through the comparison and analysis of existing relevant standards and standards, combined with the experience of electrical design, this paper summarized the correction methods of the external insulation level, electrical safety distance and the number of insulators of transmission lines and distribution devices in high altitude areas, which could provide reference for electrical design.
