摘要
随着电网容量的不断增大,输送的距离越来越远,输电线路的电压等级也在不断提高。高压输电线路产生的电磁辐射对通信线路、广播电视、人体生态是否存在影响,越来越受到人们的关注。根据研究及相关测试表明,变压器、超高压配电装置和超高压电线在运行中,会形成一定强度的工频电磁辐射。为此,本文结合我国制订的高压输电线路电磁辐射安全标准,探讨高压输电线路电磁辐射对周围环境、人体健康的影响及对无线电的干扰,通过对城区高压输电线路电磁辐射进行实地监测,并对实测结果进行分析比较,提出减轻和防护电磁辐射污染的相关措施和建议。

Abstract
With constant increase, electric ting of capacity, distance that transport more and more far, voltage grade of transmission line of electricity improve constantly too. High-pressure ic radiation that transmission line of electricity produce is it influence to store munication line , broadcast and television , human ecology in, paid close attention to more and more by people. Indicate according to research and relevant test , voltage transformer , supervoltage distribution device and supervoltage electric wire are in running , will form the ic radiation frequently of engineering of certain intensity. For this reason, this bines the high-pressure transmission line of electricity ic radiation safety standard that our country makes, probe into the impact on surrounding environment , health of ic radiation of the high-pressure transmission line of electricity and interference to the radio, Through small stream village high-pressure transmission line of electricity ic radiation go on on the spot monitoring to east week such as town such as suburb such as district such as river such as plum such as city such as Meizhou, and to survey result is it is pare to analyse to go on , is it lighten and protect relevant measures and suggestions , ic radiation of pollution to put forward.
Key words: high-voltage transmission lines power frequency ic field ic radiation pro
