Abstract

A current lead assembly for a superconducting motor comprises an epoxy base, a first copper lead, a second copper lead, a third copper lead, a fourth copper lead and a copper cover plate. Four mounting sides of the epoxy resin are used for mounting the copper leads and include two concave sides and two convex sides. The first copper lead is mounted on the first concave side. The second copper lead is mounted on the first convex side. The third copper lead is mounted on the second concave side. The fourth copper lead is mounted on the second convex side. The current lead assembly can be serially connected with three superconducting coils; the superconducting coils are sequentially connected with the four copper leads; a superconducting tape of every superconducting coil is serially connected to the copper leads by welding and is fastened with the copper cover plate.

Description

Technical field [0001] The invention relates to a series current lead applied to a superconducting motor. Background technique [0002] The superconducting motor is a new type of motor whose windings are wound with superconducting tape, which has the characteristics of low loss, light weight and high power density. The body of the superconducting tape is very fragile and easy to break, while the superconducting motor generates strong centrifugal force during the high-speed rotation, and the superconducting tape is easy to break. At present, the domestic and foreign superconducting motor projects generally adopt the welding process of red copper pillars and superconducting strips, and then install the red copper pillars and superconducting strips on the motor body by bolting and lashing. The treatment method will make the connection between the superconducting tape and the current lead unstable. Once the motor speed is too high, the superconducting tape may be damaged. Summary o...
