Abstract

The invention discloses a novel high-temperature superconducting energy storage magnet with a mixed structure, which comprises an assembly part, an REBCO coil is arranged in the assembly part, the REBCO coil is sleeved with a magnetic conductive part, the magnetic conductive part is sleeved with an MgB2 coil, and gaps exist between the REBCO coil and the magnetic conductive part and between the magnetic conductive part and the MgB2 coil. According to the hybrid magnet structure of interpolating the YBCO magnet into the MgB2 magnet, due to the fact that the YBCO material has higher critical current in a high field compared with the MgB2 material, compared with a common MgB2 magnet, the hybrid magnet structure can increase the operation current of the magnet and improve the energy storage density of the magnet. And the price of the YBCO material is relatively high, so that compared with a common YBCO magnet, the mixed magnet can reduce the manufacturing cost of the magnet, and the large size of the superconducting energy storage magnet becomes possible.

Description

technical field [0001] The invention relates to the technical field of superconducting magnets, in particular to a high-temperature superconducting energy storage magnet with a novel hybrid structure. Background technique [0002] The high temperature superconducting magnetic energy storage system has the advantages of high energy storage density, high power density, and strong power compensation capability. It has a good application prospect in operation. [0003] Large-scale superconducting energy storage magnets mostly adopt a ring structure. For large high-temperature superconducting energy storage magnets, in order to ensure that the storage energy of the energy storage system is large enough, the magnet will generate a large magnetic field. Taking the 10MJ high-temperature superconducting energy storage system as an example, the maximum magnetic field generated by it is about 3-5T, which puts forward requirements on the operating performance of the strip material for...
