摘要:
特高压直流跳线通常采用双V型悬垂串,结构复杂,增加了带电作业进出等电位的难度。为研究跳线处进出等电位的最佳路径,文中对作业人员进出等电位过程中的体表电场分布特性进行了仿真计算。研究中选取了进出等电位的8条路径,计算作业人员采用不同路径进入等电位时,体表场强值的动态变化。根据静电场仿真结果,人员偏开高压端大环1 m,从塔身水平进入等电位时体表场强平均值最低且畸变最小,安全系数最高;从横担垂直进入有发生电晕放电的危险,应尽量避免。综合考虑跳线处结构特点和实际作业情况,推荐偏开高压端大环1 m从塔身水平进入为最佳等电位进入路径。
Abstract:
Double V-type suspension strings are usually adopted in the UHV DC transmission jumper,which has a complicated structure and increases the difficulty of entering equipotential position in live working.In order to study the best path of entering equipotential position at jumper, the electric field distribution characteristics of body surface when entering the equipotential position is calculated. Eight different paths are selected to calculate the dynamic change of electric field strength on body surface when entering in each path.According to the simulation results, the electric field strength of body surface is the lowest and changes most smoothly when entering horizontally from the tower body and keeping 1 meter off the large equalizing ring, of which the safety factor is the highest. Besides entering vertically from the crossarm is the most dangerous way, which may lead to corona discharge. Taking the structural characters of the jumper and actual live working operation into consideration, entering horizontally from the tower body when 1 meter off the large equalizing ring is recommended as the safest way to the equipotential position.
