220kV架空输电线路导线架设方式与工频电磁场的关系研究

Study on the relationship between the erection method of 220kV overhead transmission line and power frequency electromagnetic field

通过理论计算220kV架空输电线路采用同塔双回逆相序、同塔双回同相序、同塔双回单边垂直挂线方式下,离地1.5m处的工频电场强度和工频磁感应强度的空间分布情况,对各相序排列产生的工频电场强度和工频磁感应强度进行对比,得出导线最优架设方式。

In this article, it will calculate the power frequency electric field strength and spatial distribution of frequency magnetic induction intensity at the distance from the ground 1.5 m of the 220 kV overhead transmission line, through the method of double reverse phase sequence of the same tower, identical sequence of double loop of the same tower, double side vertical hanging line of the same tower. And it will compare the power frequency electric field intensity and the power frequency magnetic induction intensity generated by each phase sequence, the optimal conductor erection method is obtained, and at last it will get the optimal erection mode of wire.
