摘要
在高海拔地区复杂的环境特性下,大气参数对电气设备外绝缘强度的影响是一个极其复杂的问题,直接影响着高海拔输变电工程的建设。本文结合电力设备外绝缘水平和空气间隙在高海拔地区的修正设计方法,浅析了西藏昌都地区某110 kV变电站的外绝缘及空气间隙研究计算,可为高海拔地区电气设计提供参考。
In view of the complex environmental characteristics of high altitude regions,the influence of atmospheric parameters on the external insulation strength of electrical equipment is an extremely complex issue,which directly affects the construction of high altitude transmission and transformation projects.Based on the revised design method of the external insulation level and air gap of power equipment in high altitude areas,this paper analyzes the external insulation and air gap research calculations of a 110 kV substation in Changdu,Tibet,which can provide a reference for electrical design in high altitude areas.
