摘要:
 为了全面和深入地了解高压输电线路跨越树林时的电场空间分布规律,选择红松作为研究对象,利用波导法对不同含水率下的样本进行了介电常数测量,并利用实测数据对Debye-cole模型和经验模型进行了验证和对比。结果表明:建立的经验模型在含水率较高时的预测值精确性要高于Debye模型。结合红松介电常数的测量结果,利用仿真软件对高压输电线路跨越树林时的工频电场进行了研究。
Abstract:
 In order to know the spatial distribution of electric field of the high-voltage transmission lines crossing forests,Pinus koraiensis was used as research object.The dielectric constants of samples which had different moisture contents were measured by using the waveguide method.By using the measured data,Debye-cole model and empirical model were compared.The results showed that predictive value of empirical model was more accurate than Debye-cole model when moisture content was high.Based on the measured data,the spatial distribution of electric field of the high-voltage transmission lines crossing forest were examined by simulation software.
