基于磁滞特性的自取电电源取能线圈匝数研究
|
摘要
为了优化输电线路上的取能装置,降低取能线圈体积,提高取能装置的经济性,文中着重研究了取能线圈的匝数设计。基于Jiles-Atherton磁滞理论模型对取能线圈的磁滞特性进行仿真,选择合适线圈材料,同时提出了保证线圈稳定工作在非饱和区域的最优匝数计算方法。为了安装方便,采用开合式线圈,探究气隙宽度对最优匝数的影响,计算结果表明,气隙的存在使得最优匝数减小,但是随着气隙宽度增加,气隙损耗功率显著增加,因此在制作时应尽可能减小气隙宽度。最后通过仿真和实验验证了该设计方案的有效性。
In order to optimize the self-powered supplies on transmission lines,including reducing the volume of the energy power coil and improving its economy,the optimal number of coil turns for self-powered supply is studied. Based on the JilesAtherton hysteresis theory,the hysteresis characteristics of the energy power coil are simulated to select the suitable coil material. Furthermore,the calculation method for the optimal number of coil turns,which can make the coils stably work in the unsaturated region,is proposed. Considering installation convenience,open-close coil is used and the influence of its air gap width on the optimal number of coil turns is discussed. The calculation results show that air gap causes the decrease of optimal turn optimal number of coil turns. However,power loss caused by air gap increases significantly with the increase of air gap width,so the air gap width should be reduced as much as possible. Finally,the effectiveness of the design scheme is verified by simulations and experiments.
