摘　　要：存在于电力导线周围的能量中,电场能相较其他形式能量输出更加稳定,但功率相对较小,因此,如何更高效的采集环境电场能十分具有研究意义,针对双圆筒型电场能采集器输出特性展开分析与实验研究。首先,结合Maxwell仿真,针对电力导线周围电场与电势分布特点进行分析,解释了圆筒型电场能采集器的合理性,建立电场取能等效电路,剖析了能量采集器取能原理,根据理论公式推导,分析能量采集器输出特性。其次,建立三维电场能采集器有限元模型,仿真分析了采集器极板长度、内外层极板半径等因素对能量收集的影响。最后,搭建电场取能实验平台,对相关影响因素进行了实验验证。实验表明,实验曲线与理论曲线基本吻合,证明了理论推导的正确性,增大采集器外层板外径或采集器极板长度可有效增大采集器输出电流。In the micro-source energy around the power wire,the electric field energy is more stable than other forms of energy output,but the power is relatively small.Therefore,how to collect the environmental electric field energy more efficiently is a typic of great research significance.In this paper,the output characteristics of the double tube electric field energy collector are analyzed and experimentally studied.Firstly,based on Maxwell simulation,the distribution characteristics of electric field and potential around power wire were analyzed,the rationality of cylindric electric field energy collector was explained,the equivalent circuit of electric field energy harvesting was established,the energy harvesting principle of the energy collector was expounded,and the output characteristics of the energy collector were analyzed according to the theoretical formula derivation.Secondly,the finite element model of the three-dimensional electric field energy collector is established,and the influence of the length of the plate and the radius of the plate on the energy collection is simulated and analyzed.Finally,the experimental platform of electric field energy extraction was built,and the relevant influencing factors were verified by experiments.The experimental results show that the experimental curve is basically consistent with the theoretical curve,which proves the correctness of the theoretical derivation.Increasing the outer diameter of the collector plate or the length of the collector plate can effectively increase the output current of the collector.
