对住宅小区内高压输电线周围不同层高处和不同水平距离处的工频电磁场进行了现场监测,并用模拟电荷法预测了该输电线对住宅楼不同层高和小区内不同水平距离的工频电磁场强度的影响程度。结果表明,随着与高压线水平距离及垂直距离的增加,电磁场强度呈逐渐衰减的趋势。理论计算值和现场实测值均符合国家标准限值,减轻了住宅小区内居民对高压线影响的担忧。概述我国高压电力网系统呈500kV-220kV(300kV)-110kV-
On-site monitoring of power frequency electromagnetic fields at different levels and at different horizontal distances around high-voltage power transmission lines in residential quarters was conducted. The power frequency of the power transmission lines at different levels of residential buildings and at different horizontal distances in residential areas was predicted by analog charge method The extent of electromagnetic field intensity. The results show that with the increase of the horizontal distance and the vertical distance from the high voltage line, the electromagnetic field intensity gradually declines. Theoretical calculations and field measurements are in line with national standards limit, reducing the residential area residents on the impact of high voltage lines. Overview China's high-voltage power grid system was 500kV-220kV (300kV) -110kV-
