Research on Energy Extraction Devices Based on High-Voltage Line Monitoring Technology

Abstract

Abstract With the construction and development of an intelligent power grid, the voltage level of transmission lines is constantly improved. The distribution of power grids is increasingly broad, the climate environment along the transmission lines is complicated, the safe and reliable operation of transmission lines is facing significant challenges, and the inspection and maintenance workload of transmission lines is also increasing. Currently, only 20% of the online monitoring devices of transmission lines installed by the State Grid can operate normally. Power failures cause the most. It can be seen that it is necessary to develop an efficient and reliable power supply to improve the reliability of online monitoring devices of transmission lines. In order to enable the transmission lines to operate independently without maintenance for a long time, now the power grid needs an energy harvesting device with good stability, high energy harvesting efficiency, and strong resistance.
