高原山地500kV输电线路雷电屏蔽特性试验研究
Research on Lightning Shielding Characteristics of 500 kV Transmission line in Plateau Mountain
摘要
Abstract
In order to better understand the probability distribution of space around the each lightning point and influences of ground wires protection angular of the 500 kV transmission line on the shielding performance, using the 500 kV typical transmission lines as examples, we established a model of reducing transmission line tower to simulate the shielding failure. The experimental results verify the superiority of the negative protection angle in the antishielding performance, and reveal that, the closer the transmission lines are, the more the strike is; from the central tower head to file, the probability of shielding failure increases first, then decreases. The research results provide a scientific basis for the design of lightning protection of 500 kV transmission lines.关键词
