摘要
对日常生活中的工频电磁场对人体的影响和防护问题进行研究:首先通过电磁场测试仪器对选定的几处典型变配电场所进行实地测量;其次运用Maxwell 2D/3D软件搭建日常生活中常见的电气设备模型并进行计算机防真,得出设备周围的磁感应强度值,并对防护措施的电磁屏蔽效果进行仿真验证;最后给出对强电桥架、母线槽及变压器等电气设备的具体有效的防护方法。
The research is made on the impact of power-frequency electromagnetic field on human bodies in daily life and the method for protection： first of all, the electromagnetic field （EMF） test instrument is used for field measurement of several typical power transformation and distribution sites selected; secondly, Maxwell 2D / 3D is used for setting up some electrical equipment models in daily life for computer simulation to get the values of magnetic induction around the equipment, and simulation verification is carried out for the electromagnetic shielding effect of some preventive measures; finally, the effective protective methods are provided for electrical equipment, e.g. heavy-current cable trays, bus ducts and transformers.
