海拔高度对直流离子流场影响的研究

Research of Influence of Altitude on DC-Ion-Flow Field

本文分析了单极性高压直流输电线下地面附近离子流场的分布规律及其影响因素,并用同一单极性直流输电线路的缩尺模型分别在武汉、西宁进行测量。通过试验研究得到了不同海拔高度地区高压直流输电线路的电晕电流、地百附近的离子流密度和场强的特性规律以及海拔高度对其影响程度。

It analyses theoretically the distribution regularity and the influence factors of ion-flow field near ground under single pole HVDC transmission line and measurement is done using the reduced model of the line in HV Lab. It gives the influence of altitude on corona current, ion-flow density and field strenth near ground under HVDC line.
