Abstract

The invention relates to a bracket-suspending vacuum sleeve circulating liquid nitrogen superconducting circuit which comprises leads, a liquid nitrogen tube, a composite outer tube and liquid nitrogen, wherein the leads and the liquid nitrogen tube are respectively fixedly suspended in the center of the liquid nitrogen tube and the center of the composite outer tube by a polygonal lead bracket and a liquid nitrogen tube bracket which are arranged at intervals. The circuit can be laid in grooves, and the pressurization injection and overflow of the liquid nitrogen are set discontinuously for monitoring and maintaining a station of a vacuum state of a vacuum tube. The bracket suspended vacuum sleeve circulating liquid nitrogen superconducting circuit of the invention has reasonable design, simple structure, convenient manufacture and laying, and low cost in maintenance and monitoring, and is suitable for long-distance high-capacity electrical transport, thereby having good popularization and use value.

Description

1. Technical field: [0001] The invention relates to a circuit for transporting electric energy, in particular to a superconducting circuit for circulation of liquid nitrogen in a vacuum casing with a bracket suspended in the air. 2. Background technology [0002] Onnes discovered superconductivity at low temperature in 1911, and it has been nearly a hundred years since its related theoretical research, laboratory research, thermonuclear fusion experimental reactor, large proton collider energy storage device and other application fields have achieved considerable results. Medical magnetic resonance human body imager, magnetic levitation high-speed train, etc. have entered the market. The application in national defense and military industry has been highly valued by many countries, which have revealed the brilliant prospects and huge productivity potential of superconducting applications. However, the research in the application field of transmission power lines is relative...
