V形复合绝缘子力学特性研究
Characteristic Study for Windage Yaw Analysis of V-Shape Composite Insulator String
摘要
Abstract
Windage yaw discharge is one of the most disastrous problems for the normal operation of state grid.Accounting for windage yaw problem of V-shape composite insulator string used in Hami-Zhengzhou ultrahigh voltage direct current transmission line,a practical calculation method is developed based on string polygon method for I-shape pan insulator strings.Finite element analysis is used to verify the validation and effectiveness of proposed method.Calculation method of minimum axial tension force determining its application range is also presented.Then windage yaw characteristic study is conducted for Hami-Zhengzhou ultrahigh voltage direct current transmission line,with the influence analysis of mean height of conductors,insulator string angle,horizontal span and vertical span.The results indicate that,with given vertical and horizontal span length,the suggested angle of insulator string increases with the increase of mean height of conductors;with given mean height of conductors and vertical span length,the suggested angle of insulator string increases with the increase of horizontal span length;with given mean height of conductors and horizontal span length,the suggested angle of insulator string decreases with the increase of vertical span length.The suggested angle of insulator string under different conditions are presented.关键词
