【摘要】 建立成年人和未成年人的人体模型,采用Comsol仿真软件分别计算分析特高压交流输电线路对成年人和未成年人产生的磁场效应,并对结果进行对比。结果表明,成年人和未成年人有相似的磁感应强度分布规律,人体磁感应强度和外围空气的分布一样,都呈圆弧形分布。就特高压输电线路在头部产生的磁感应强度大小来说,成年人比未成年人大。就产生的感应电场强度而言,最大值出现在头皮最上方位置,分别是0.251 m V/m和0.163 m V/m。将计算结果与国际非电离辐射防护委员会(International Commission on Non-Ionizing Radiation Protection, ICNIRP)制定的导则限值相比较,结果表明,磁感应强度的大小无论是对专业人员还是对于普通民众均在ICNIRP导则限值范围之内。特高压输电线路所产生的电磁暴露对成年人和未成年人都是安全的。更多还原

【Abstract】 Human body models of adults and minors were established, and Comsol simulation software was used to calculate and analyze the magnetic field effects of ultra-high voltage(UHV) AC transmission lines on adults and minors. Calculation results were compared with the guidelines established by the International Commission on Non-Ionizing Radiation Protection(ICNIRP). The results showed similar circular-shaped distributions of magnetic induction intensity in the bodies of both adults and minors as well as in the surrounding air. The magnitude of the magnetic induction intensity generated by the UHV transmission lines on the head was greater for adults than for minors. In terms of the induced electric field strength, the maximum value presented at the top of the scalp, with values of 0.251 and 0.163 m V/m for adults and minors, respectively. Comparison of the calculation results with the ICNIRP guidelines demonstrates that the magnitude of the magnetic induction intensity is within the limits of the ICNIRP guidelines for both occupational and general public exposure. Electromagnetic exposure from UHV transmission lines is safe for adults and minors.更多还原
