Abstract

The embodiment of the invention discloses a wireless power supply method and device for high-voltage on-line monitoring equipment. With the method and device, a problem of low power supply reliability of the wireless power supply method of the existing high-voltage on-line monitoring equipment and problems of a power supply distance, power and efficiency, power supply stability and reliability, and power supply cost can be solved. The method comprises: step one, an energy-taking coil takes energy out from a high-voltage bus in an electro-magnetic induction manner and AC/DC and DC/AC voltage conversion is carried out to convert 50-Hz alternating currents into high-frequency alternating currents; step two, a transmitting coil disperses the energy of the high-frequency alternating currents to the surrounding space and thus a high-frequency electromagnetic field is formed in the space, targeted transmission of the energy is carried out by using a domino relay coil, and a receiving terminal receives the energy; and step three, after the receiving terminal receives the energy, power conversion processing is carried out and then the converted power is provided for a storage battery and a load.

Description

technical field [0001] The invention relates to the field of on-line monitoring, in particular to a wireless power supply method and device for high-voltage on-line monitoring equipment. Background technique [0002] With the continuous expansion of the power grid scale and the interconnection of regional power grids, the operation and control of the power system are becoming more and more complex. Whether the electric energy can be successfully received by the load, and the general high-voltage transmission line is located in a complex outdoor environment, spans a large area, and the climate is changeable. Failures in the insulators, lightning arresters and other firmware in the transmission line may cause large-scale power outages, resulting in great social and economic losses. Therefore, on-line monitoring of high-voltage transmission lines, early detection of faults and early warning can effectively avoid the occurrence of power outages. [0003] At present, a variety ...
