Description

technical field

[0001] The invention belongs to the technical field of resonant wireless energy transmission, in particular to a resonant wireless power supply system for high-voltage transmission lines. Background technique

[0002] High-voltage and ultra-high-voltage power grid monitoring terminals are crucial to ensure the stable operation of the power grid, and are an indispensable part of a modern power grid characterized by informatization, automation, and interaction. However, energy issues are always the key issues that limit smart grid monitoring and management. Most of the traditional solutions use distributed energy such as wind energy and solar energy, but the inherent instability of distributed energy makes it impossible for terminal equipment to obtain reliable energy guarantees. The problem is even more serious in the environment with more rainy weather in the south. On the other hand, there is sufficient power on the high-voltage transmission / distribution li...
