Description

technical field [0001] The invention belongs to the technical field of wireless energy transmission, and in particular relates to a wireless power supply system of an energy and signal simultaneous transmission mechanism and high-voltage line monitoring equipment. Background technique [0002] The power supply methods of online monitoring equipment for high-voltage lines mostly use batteries, solar panels or wind power generation. Regular replacement of batteries will consume a lot of manpower and material resources, and there will be great safety hazards; wind and solar power generation will be limited by natural environmental conditions, and the application limitations will be relatively large. In recent years, a new type of power supply solution for online monitoring equipment of high-voltage transmission lines that combines Wireless Power Transfer (WPT) technology with current transformers (Current Transformer, CT) has attracted widespread attention and is considered to ...
