Embodiment Construction

[0025] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0026] Superconducting material refers to a material with superconductivity, which is a good conductor with low resistance at room temperature, but as the temperature drops, its resistance decreases. When the temperature reaches the critical temperature TC (the superconductor changes from a normal Below the critical temperature at which the state transitions to a superconducting state with zero resistance), their resistance suddenly disappears. High-temperature superconducting materials are mainly divided into two types: yttrium barium copper oxide (YBCO) and bismuth strontium calcium copper oxide (BSCCO).

[0027] YBCO, full name Yttrium Barium Copper Oxide, refers to yttrium barium copper oxide, which is a crystal with the chemical formul...

Abstract

The invention relates to the technical field of wireless energy transmission, in particular to a superconducting resonator of a YBCO film structure and a wireless energy transmission device. The superconducting resonator comprises a substrate and a YBCO microstrip line arranged on the substrate. The YBCO microstrip line is a complete left spiral strip and specifically comprises a plurality of annular belts which are sequentially arranged from inside to outside; openings are formed in the annular belts and formed in the same straight line; the two ends of each opening are an upper connecting point and a lower connecting point respectively; and in adjacent two annular belts, the lower connecting point of the outer annular belt is connected with the upper connecting point of the inner annularbelt through a connecting strip. The resonator provided by the invention works in a liquid nitrogen temperature zone and can be used as a repeating coil, a transmitting coil or a receiving coil for wireless energy transmission, the resonator adopts a rectangular spiral resonance ring and has a compact structure and a high capacitance effect, so that the resonance frequency is low, the applicationof a magnetic resonance wireless energy transmission system is met, the transmission efficiency is high, the complexity of the system is low, and the total loss of the system is small.

Description

technical field [0001] The invention relates to the technical field of wireless energy transmission, in particular to a superconducting resonator with a YBCO film structure and a wireless energy transmission device. Background technique [0002] Wireless energy transfer technology is a cutting-edge topic integrating basic research and applied research. It uses electromagnetic waves as a carrier to transmit energy, and has more advantages than wired electric energy. It overcomes the fact that the traditional wired power transmission method cannot meet the needs of some special applications, such as mines and water, etc. In these environments, these shortcomings caused by the traditional cable power supply method are often fatal and sometimes cause explosions. Fire and equipment damage, etc., have brought great safety hazards and economic losses. In addition, in daily life, wireless power transmission can avoid or reduce the entanglement of electrical wires used by people, ma...
