Problems solved by technology
The biggest disadvantage of this kind of current lead is that the larger the current passed by the current lead, the stronger the magnetic field generated by itself. Due to the magnetic field dependence of the high temperature superconducting material, the magnetic field generated by itself will reduce the critical current of the high temperature superconducting material, invisible caused a decrease in the flow capacity of the system

A high-temperature superconductive coaxial current lead transmission system belongs to the field of application of superconductor in electrical engineering, and comprises two coaxial current leads and a power supply circuit. Each coaxial current lead is composed an internal current layer and an external current layer which are coaxially arranged, and the current directions in the internal and theexternal current layers are opposite; the internal current layer of each coaxial current lead is connected with the external current layer of the other coaxial current lead in parallel to form a current assembly; and the current assembly is connected with the two ends of the both the power supply circuit and a superconducting device to form a loop. The internal current layer and the external current layer can also be both connected with resistors in series. Compared with the prior current lead, the inventive current lead can remarkably improve the current-carrying capacity of a system under the same consumption of the high temperature superconductive belt material, and can remarkably reduce the consumption of the high temperature belt material under the same critical current, so as to reduce system heat leakage and reduce manufacturing cost.
Description
A High Temperature Superconducting Twin Coaxial Current Lead Transmission System technical field A high-temperature superconducting twin coaxial current lead wire transmission system belongs to the field of superconducting engineering applications. Background technique The invention provides a novel current lead transmission system. Compared with the traditional current lead transmission system, the current carrying capacity of the current lead can be greatly improved with the same amount of superconducting material used. On the premise of the same current carrying capacity, the amount of superconducting material used can be greatly reduced, thereby reducing the demand for cooling power of the current transmission system. The current lead is a current transmission device connecting the large low-temperature superconducting magnet, the low-temperature superconducting device and the current source. Among them, large-scale low-temperature superconducting magnets mostly wor...
