摘要:
This paper presents an analytical model to determine ac losses in monolayer and multilayer superconducting solenoids. The case of a transformer with several coils is also presented. This model is based on an infinite cylindrical geometry and the Bean model. Under this assumption, the electromagnetic variables distributions are determined and then instantaneous losses are simply calculated. For a monolayer coil the mean losses are given too. Then, analytical results are compared to numerical results performed with previous development in Flux3D (finite elements software). Finally, a comparison with measurements on a two-layer coil is presented.
