| 摘 要： | 为了预估四相输电线路的电磁场辐射,弄清四相输电线路与现有三相输电线路在电磁场辐射状况的异同,计算了四相和三相超高压输电线路附近地面电场强度的量值,并以一条实际拟建的500 kV单回三相线路为参照,通过对四相和三相不同架设方式输电线路地面电磁场辐射强度的对比分析,得出了四相输电系统能有效地减小输电线路的电磁辐射,提高输电密度的结论.

| Abstract: | .For evaluating the electromagnetic field intensity of four-phase power transmission lines and contrasting the difference of electromagnetic field radiation between four-phase and three-phase power transmission lines, this paper calculates the electromagnetic field intensity of high voltage transmission lines. And based on the standard of a 500 kV high voltage power transmission lines,though the comparison of electromagnetic field impact to environment between four-phase and three-phase transmission lines which are arranged in different ways ,it concludes that the four-phase power transmission system can decrease the electromagnetic field radiation and increase the density of power transmission. |

| Keywords: | four-phase power transmission intensity of electromagnetic field ~ electromagnetic radiation density of power transmission |
