摘要
导出了环形线圈的磁感应强度空间分布解析表达式,并通过数值仿真分析了磁感应强度在试验平面上的变化特性和磁场空间分布特性;介绍了用于直流高磁场强度的环形线圈和150kHz～1MHz磁场抗扰度试验系统;最后对分析结果进行了实验验证。
Analytical expressions of magnetic field spatial distribution in loop coil are developed.The characteristics of magnetic induction strength variation in test plane are analyzed by numerical simulation.The spatial distribution of magnetic field is discussed.The loop coil for high magnetic field strength at direct-current and the magnetic field immunity test system for 150 kHz to 1 MHz frequency range are provided.Finally,the results are experimentally verified.
