A transition metal plate (2) is connected between the omega-shaped current lead connecting terminal welding deformation and transition section (3) and a conventional conductor (1); and the transition metal plate (2) is welded between the omega-shaped current lead connecting terminal welding deformation and transition section (3) and the conventional conductor (1).

Description

technical field [0001] The invention relates to a terminal joint device, in particular to a terminal transition connection device for high-current high-temperature superconducting cables. Background technique [0002] The difference between high-temperature superconducting cables and conventional cables is that high-temperature superconducting cables use high-temperature superconducting materials with zero resistance and large current transmission characteristics as conductors, and use cheap liquid nitrogen as cooling medium, and their transmission capacity is that of conventional cables. 3 to 5 times, with the advantages of large transmission capacity, small electromagnetic pollution, and low loss, it is an important way to achieve large-capacity, low-loss power transmission. The high-temperature superconducting cable terminal is an important part of the high-temperature superconducting cable system. The high-temperature superconducting cable terminal includes three parts: ...
