Abstract
In order to solve the problems of poor safety performance, nonuniversality 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 highefficiency power supply device.
