论述了多分裂输电线路对电视信号的干扰影响机理 ,利用解析法得出了多分裂输电线路对电视波的散射场的计算公式。计算了特高压 4分裂及 8分裂线路对电视信号的干扰影响 ,得出了各种情况下散射场的分布曲线 ,包括电视波入射角、电视波频率、观测点位置等对散射场分布的影响规律。对多分裂导线对电视信号的多次散射所引起的共振态和反共振态进行了具体分析 。
Television interference from scattering effects of very high voltage transmission line is discussed. Using an analytical method, corresponding calculation formula for scattering fields are obtained. Some results about corresponding calculation formula for scattering fields and its distribution curves are obtained, it's including incident angle of television wave, wave frequency and view point distance to transmission line respectively. By analyzing the resonance and de-resonance characteristics of scattering fields due to multi-reflections among multi-lines, some methods to minimize the interference are presented.
