±800kV输电线路带电作业电场仿真分析
Simulation Analysis of Electric Field on Live Working of ±800 kV Transmission Line
摘要
Abstract
To ensure the safety of both lines and working staff when live working on ± 800 kV ultra-high voltage DC (UHVDC) transmission lines.The tower model,insulator model,transmission line model and human body model are established by Ansoft software.The finite element method is used to calculate and analyze the electric field intensity on different parts of the human body.The results show that when two people upright into electric field along the insulator,the surface field of human body,when moves to the 1/4 insulator,is about 5 ~ 15 kV/m.The surface field of human body,when moves to the 1/2 insulator,is about 10~30 kV/m.Hanging basket method is used to human body into electric field,human body at the tower cross,are safety.When the hanging basket moves to about 3 m away from the shielding ring,the body surface strength is about 41 ~ 195 kV/m,and when the operator reaches the equipotential,the surface strength of the operator exceeds510kV/m,and special shielding measures should be taken.关键词
