摘要：
The no-insulation (NI) winding technique has been widely used in high magnetic field applications to enhance the thermal stability of superconducting magnets. Eliminating the insulated layers also creates an additional path for current flow, even if the superconducting tapes have resistive joints. This so-called "defect irrelevant" characteristic further improves the economy of the superconducting facility. This article introduced a 2-D method for the transient thermal analysis of an NI coil with several resistive joints. The power loss and temperature rise under different working conditions are calculated by the 2-D model, and experimental results from the reference are compared with validate the simulation model.
