摘要: 以某8塔共址的中波发射台为例,对多个不同发射功率的发射塔同时运行时地面电场强度进行40 V/m等值线标准方法的计算与实测。结果显示,仅2座发射功率≥50 kW发射塔周围可实测到40 V/m等值线,实测值与国家环境行业标准规定方法计算结果相差约30%。

关键词: 中波发射台, 地面电场强度, 40 V/m等值线

Abstract: The ground Electric field strength wastheoretically estimated and measured, with respect to the 40 V/m contour standard method, for several medium-wave transmitting towers with different radiationpower run at the same time, with an 8-tower collocated medium-wave broadcasting station taken as an example. It shows that only two towers with power greaterthan 50 kW can be measured to 40 V/m contour, and the difference between the values and the results estimated with the national environmental industry standardmethod is about 30%.

Key words: Medium wave antenna, Ground electric field strength, 40 V/m contour
