嵌入式附建变电站电磁辐射实测分析

Measurement and Analysis of Electromagnetic Radiation of Embedded Substation

文章分析了变电站电磁辐射的传播特性,对比研究国内外多种用电设备和作业环境的电磁辐射的标准,对一种新型的嵌入式附建变电站内部和室外电磁辐射进行现场检测:实际测点处的电场强度是国家标准值的2.3/10000~5.8/10000;磁场强度范围是国家标准值的0.01/100~1.47/100,结果显示,不管是在附建变电站内部还是外部,电场强度和磁场强度都远低于国家标准限值,是安全的.

The article analyzes the propagation characteristics of electromagnetic radiation in substations.It studies the standards of electromagnetic radiation in a variety of electrical equipment and operating environment at home and abroad.Through on-site detection of electromagnetic radiation inside and outside of a new type of embedded attached substation,the electric field strength at the actual measuring point is 2.3/10000〜5.8/10000 of the national standard value;the magnetic field strength range is 0.01/100〜1.47/100 of the national standard value.Therefore,whether it is inside or outside the attached substation,the electric field strength and magnetic field strength are far lower than the national standard limit,which is safe.
