摘要(Abstract)：

无线输电技术与常规有线电能传输相比,具有方便灵活、高效、节省空间等优点,成为了热点技术。与能量在自由空间传播相比,无线输电的电磁环境有很大不同,而电磁安全问题也变得日益突出。针对此问题,首先设计并研制了6组百瓦级多频点无线输电样机,然后利用电磁测试仪器Narda-NBM520测试了不同工作频率下的无线输电样机周围的电场强度、磁场强度和功率密度,并与电磁辐射公众安全限值进行对比,结果表明在距离线圈50 cm以上时电场强度、磁场强度和功率密度才符合安全标准。最后分析了无线输电样机对电网接入点的计量和电子开关的影响,结果表明,电表在高频磁场影响下出现了部分计量偏差,极限情况下电子开关出现了损毁情况。
