重庆地区电网覆冰的海拔高度特性
Altitude Characteristics of Ice-covering in Chongqing Power Grid
摘要
Abstract
To learn the situation in Chongqing ice on power transmission line is of significance for design and selection of appropriate measures of preventing ice.Consequently,according to the analysis of the icing factors,we surveyed the ice conditions in Chongqing area in particular climate and terrain conditions,studied the Chongqing power grid and geographical distribution of ice thickness between altitude variations,established a mathematical model according to the relationship between the ice thickness in Chongqing area and elevation,and analyzed the altitude characteristics of ice-covering in Chongqing power grid.The results show that ice-covering of the Chongqing power grid ice concentrates on the mountain areas in the northeast and southeast regions,altitude on ice thickness has a significant effect,and the ice thickness on transmission line increases with altitude in an exponential rate.关键词
