摘要

为解决状态监测装置电源对输电线路的能量收集(EEH)效果不理想的问题。作者设计了三种基于交流电场感应的 EEH 方案,可有效提高负载电源的输出功率。详细分析了每种方案的 EEH 原理,并分析了外能量收集器形状、电容补偿和阻抗匹配特性等影响因素。最后,实验表明,当线路电压水平为 10 kV 时,直接模式场 EEH 可获得 140.9 mW 的功率。高电位场 EEH 模式获得了 4.1 mW 功率。与铝线电位相同的内能量收集器的收集效果明显更好,获得了 30.7 mW 的功率。最后,基于第三种模式,当负载电阻为 2200 Ω 时,整流器获得了 23.7 mW 的直流输出。实验结果与理论分析一致,验证了电场感应供电技术的有效性。

Energy harvesting technology for AC overhead insulated transmission line based on electric field induction

Energy harvesting technology for AC overhead insulated transmission line based on electric field induction

To solve the problem of the energy harvesting (EEH) effect of the condition monitoring devices power supply on the transmission line is not ideal. The authors designed three kinds of EEH schemes based on AC electric field induction, which can effectively improve the output power of load power supply. The EEH principle of each scheme was analysed in detail, and the influence factors such as the shape of outer energy harvester, capacitance compensation and impedance matching characteristics were analysed. Finally, the experiment showed that 140.9 mW of power was obtained in direct-mode field EEH when the line voltage level was 10 kV. The high-potential field EEH mode obtained 4.1 mW of power. The harvesting effect of the inner energy harvester with the same potential as the aluminium wire was obviously better, and 30.7 mW of power was obtained. Finally, based on the third mode, when the load resistance was 2200 Ω, the rectifier received 23.7 mW DC output. The experimental results are in agreement with the theoretical analysis, which verifies the effectiveness of the electric field induction power supply technology.
