Altitude Correction of Switching Impulse Flashover Voltage of Rod-plane Air Gap
摘要
Abstract
Because more and more transmission projects will pass through high altitude areas,it is important to study altitude correction method for air gap discharge.To deep study the influence of altitude on switching impulse characteristics of rod-plane gap,we experimentally investigated positive switching impulse flashover in Beijing,Guiyang,Xining and Yangbajing,and compared test results with correction results using existing altitude correction methods.Meanwhile,other correction methods were discussed,including three interpolation methods,and two correction methods whose coefficients change with gap distance.It is concluded that,existing correction methods are not suitable for altitude correction of rod-plane air gap discharge in the range of 0~4300 m.The correction errors of linear interpolation method and altitude correction method whose coefficients change with gap distance are small,and these two methods are recommended to be used in project design.关键词
