摘要
为研究高压交流输电线路电场生态效应问题,通过对工频磁电场特性、生态效应及改善措施的分析,建立模型,计算电场中人体感应电流、人体内部电场强度及人体离子移动幅度。结果表明:高压交流输电线路产生的工频电场强度为4kV/m时,通过人体的总感应电流为60μA,人体内部电场强度为0.176×10^(-3)V/m,人体头部离子移动幅度为8.01×10^(-12)m。
To study the ecological effect of electro-magnetic field of HV AC transmission line, with analyzing the characteristics of its power frequency electro-magnetic field, the ecological effect and the improvement measures, model was built to calculate human induced current, human internal electric field intensity, human ion displacement amplitude. Results showed that when power frequency electric field intensity from HV AC transmission line was 4 kV/m, total induced current passing through human body is 60 μA, human body internal electric field intensity is 0.176×10^-3 V/m, and human body ion transferring amplitude is 8.01×10^-12 m.
