备注

随着公众环保意识的提升,高压输电线路周围的电磁环境问题受到越来越多地关注,关于电磁污染引起的一些纠纷及案件也日益增加。而确定线路下方电场效应、无线电干扰和可听噪声等电磁环境参数是输电线路设计的关键问题之一。文中针对电磁环境中的4个主要电磁参数进行了研究,并基于对这些参数的分析确定了线路的设计方案。文中以陕西某条设计中的330 kV同塔双回交流输电线路为研究对象,详细分析研究其电磁参数。计算了腰型和紧凑型2种塔型下的导线表面电场强度、无线电干扰、可听噪声等电磁参数,对同相序和异相序2种情况下的各参数进行对比分析后,给出了最佳设计方案,为实际线路设计提供了有效的参考依据。

With the enhancing of public's awareness of environmental protection,high voltage transmission lines surrounding electromagnetic environment problem isattractingmore and more attention,identify the electric field effect,radio interference and electromagnetic environment parameters,such as audible noise below lines is one of the key problems in transmission line design.In this paper,the electromagnetic environment of the four main electromagnetic parameters were studied,and based on the analysis of these parameters,determine the line of the design.Taking Shaanxi 33 kV double-circuit AC transmission lines as a research object,its electromagnetic parameters were analyzed in detail.Calculated waist type tower wire surface electric field strength of compact tower tower under two kinds of radio interference,audible noise,and electromagnetic parameters,and various parameters with different phase sequence and same phase sequence for two kinds of case were comparatively analyzed,to provide reference for circuit design.
