摘要
阐述了由于城市室内配电房的广泛应用而造成环境电磁污染问题,以及国内外研究简况.构建了配电房母线磁场分布计算的简化模型.采用解析法和二维有限元法分别进行了计算分析,具体考虑了母线长度、间距、高度等布置方式对周围工频磁场分布的影响,并对两种计算结果进行了对比分析,提出了二维有限元法的适用条件,为进一步的电磁污染治理提供了理论依据.
The environment electromagnetic field pollution problems caused by indoor distribution substation busbars and its research situation around the world are described. A simplified calculation model of magnetic field from substation busbars is established. Analytical method and 2D finite element method are used in the calculation, considering the busbar structure such as its length, spacing and height in detail. The calculation results of these two methods are compared; and the applying limit of 2D finite element method is proposed. The research results are useful to protect environment from magnetic field risks.
