Wireless power transmission system applied to power supplying of high voltage line device

Abstract

The invention discloses a wireless power transmission system applied to power supplying of a high voltage line device. The system is directly connected with a high voltage power transmission circuit through a large power sensing power taking device, power is directly connected with alternated current power by utilizing a mutual inductance principle, and then the alternated current power is rectified and stabilized through a large power multi-way output rectifying stabilizing device to provide direct current standing bias voltage for a separately excited high frequency power supply; and the separately excited high frequency power supply is connected with a wireless power transmission energy emitter, high frequency power is transmitted to the wireless power transmission energy receiving device and a small power rectifying stabilizing matching device on the basis of a magnetic coupling resonance technology, and finally the power is supplied to the high voltage line device. The system supplies the power to an on-line monitoring device in a wireless transmission mode, and meanwhile the system is light in weight and small in size, can be directly hung on a high voltage aerial transmission wire, and achieves long-distance, high-reliability and high stability power supplying.

Description

technical field [0001] The invention relates to a wireless power transmission system applied to power supply of high-voltage line equipment, and belongs to the technical field of wireless power transmission. Background technique [0002] In recent years, with the rapid development of the power industry, the power system is developing towards high voltage and large capacity, and it is becoming more and more important to ensure the stable operation of the power system. Once a power failure occurs, it will bring serious consequences. [0003] In order to prevent the occurrence of catastrophic accidents and reflect the operation status of power equipment in time, it is very necessary to carry out state monitoring and fault diagnosis of power equipment. There are more and more online monitoring equipment on power transmission and transformation lines, and the coverage is getting wider and wider, which makes the equipment have higher and higher requirements for field power supply...

Problems solved by technology

[0004] At present, the most widely used power supply method is solar power supply, but this method is greatly affected by climate conditions and lacks long-term maintenance-free capabilities

Laser power is used in electronic current transformers and active optical current transformers, but such power supplies are also not suitable for field work
