摘要

采用计算机模拟的方法,研究了中高压地下电力电缆线路在具有磁性的复合聚乙烯管中,使用不同尺寸(体积)的特殊松散填土/填土时的磁场。电缆周围和附近的管道和额外土壤由具有有效磁性的复合材料制成,可以作为磁屏蔽,降低地面磁场水平。分析了场屏蔽的效率取决于松散填充/填充复合土的高度和宽度。揭示了为最佳缓解电缆正上方地面上的磁场而存在的最佳非大(高度)填土,以及松散填土/填土宽度对屏蔽效率的影响。介绍了复合松散填土的可用性和不可用性对磁场分布和磁场水平的影响。显示了在一个管道中布置(三叶)电缆的优点,该管道具有额外的复合松散填料和填充土。参考文献30,图5。

POTENTIAL MEANS FOR MITIGATION OF MAGNETIC FIELD GENERATED BY UNDERGROUND POWER CABLES IN POLYETHYLENE PIPES MADE OF COMPOSITE MAGNETIC MATERIAL
The magnetic field of the medium- and high-voltage underground power cable line, laid in composite polyethylene pipes having magnetic properties, with the use of special loose-fill/fill-up soil of different dimensions (bulk) is studied by computer modeling. The pipes and additional soils around and near the cables are made of a composite material with effective magnetic properties and can act as a magnetic shield that reduces the level of the field on the ground. The effi-ciency of field shielding depending on the height and width of the composite loose-fill/fill-up soil is analyzed. The exis-tence of the optimal not large (in height) fill-up soil for the best mitigation of the magnetic field on the ground directly above the cables and the influence of the width of the loose-fill/fill-up soils on the shielding efficiency are revealed. The characteristic features of the magnetic field distribution and the field level depending on the availability or non-availability of composite loose-fill soil are presented. The advantages of (trefoil) cable arrangement in one pipe with additional composite loose-fill and fill-up soil are shown. References 30, figures 5.
