摘　　要：为解决输电线路感应取电装置安全性能差、不具有通用性以及取电功率低的问题,对感应取电装置进行优化设计研究。设计继电器和瞬态双向抑制二极管TVS的双重保护电路,实现对电网及装置的保护;继而分析取能线圈参数,以保证小电流时输出功率可达到33 W,同时可以稳定输出12 V和5 V的电压。优化后的装置可适用于输电线路的监测设备,也可应用于雷击定位、故障测距、导线温度监测等设备,充分保证装置的广泛适用性;并设计锂电池电量显示功能,避免锂电池的过充过放。最后,通过Saber软件仿真和实验验证该优化设计的可行性。经测试,改进的感应取电装置是一种更加安全稳定、可靠通用的高效率取电装置。In order to solve the problems of poor safety performance,non-universality and low power of inductive power on transmission line,this paper designs and studies the optimal design of induction power supply device on transmission line.A double protection circuit of relays and TVS diodes is proposed to protect the power grid and its equipment.Then,the parameters of induction coil are analyzed to ensure that the output power can reach 33 W at a low current,and the output voltages of 12 V and 5 V can be output stably.The optimized device can be applied in transmission line monitoring,thunderstroke orientation,fault locating and conductor temperature monitoring devices.The wide applicability of the induction power supply device is guaranteed.Meanwhile,a status display function of lithium battery is integrated in the device to avoid overcharge or over discharge.Finally,the feasibility of the optimized design is verified by the Saber software simulation and experiments.It is indicated that the improved induction device is a secure,stable,reliable,universal and high-efficiency power supply device.
