چکیده انگلیسی
In this paper we present the development of a new hybrid energy transfer line with 30Â m length. The line is essentially a flexible 30Â m hydrogen cryostat that has three sections with different types of thermal insulation in each section: simple vacuum superinsulation, vacuum superinsulation with liquid nitrogen precooling and active evaporating cryostatting (AEC) system. We performed thermo-hydraulic tests of the cryostat to compare three thermo-insulating methods. The tests were made at temperatures from 20 to 26Â K, hydrogen flow from 70 to 450Â g/s and pressure from 0.25 to 0.5Â MPa. It was found that AEC thermal insulation was the most effective in reducing heat transfer from room temperature to liquid hydrogen in â¼10Â m section of the cryostat, indicating that it can be used for long superconducting power cables. High voltage current leads were developed as well. The current leads and superconducting MgB2 cable passed high voltage DC test up to 50Â kV DC. Critical current of the cable at â¼21Â K was 3500 A. It means that the 30Â m hybrid energy system developed is able to deliver â¼50-60Â MW of chemical power and â¼50-75Â MW of electrical power, i.e. up to â¼135Â MW in total.
