Abstract

The invention relates to a Hough-type transition connection device for a large-current high-temperature superconducting cable terminal. A Hough-type current lead terminal of the Hough-type transition connection device is formed by arranging two symmetrical arch current lead terminals oppositely up and down. The middle circular arc parts of the two arch current lead terminals are Hough-type current lead terminal connection sections (6); and two upper straight plate parts and two lower straight plate parts of the two arch current lead terminals are Hough-type current lead terminal welding deformation transition sections (3), and a plurality of through holes (9) are uniformly distributed on the Hough-type current lead terminal welding deformation transition sections (3). Indium metal layers (5) are plated on the inner circular arc surfaces of the Hough-type current lead terminal connection sections. Transition metal plates (2) are connected between the Hough-type current lead terminal welding deformation transition sections (3) and a conventional conductor (1). The transition metal plates (2) are connected with the Hough-type current lead terminal connection sections (6) and the conventional conductor (1) by welding.

Description

technical field [0001] The invention relates to a terminal transition connection 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 includ...
