Description

【Technical field】 [0001] The invention relates to the technical field of electric power, in particular to the technical field of non-contact power-taking equipment and corresponding load equipment on high-voltage lines. 【Background technique】 [0002] With the rapid development of my country's economy, all walks of life have an increasing demand for electric power, and the requirements for the stability, uninterrupted and shock recovery of the provided electric energy are also increasing day by day. As the lifeline of the power system, the safety and stability of high-voltage transmission lines and supporting equipment also put forward high requirements. There are a large number of equipment circuits that use non-contact induction power collection to stably control high-voltage lines, and can achieve self-protection of high-voltage lines without the help of external energy such as wind and solar energy. Inductive power harvesting can obtain electric energy much lower than t...
