高导铝稳定化超导Monolithic导体耦合损耗

Coupling Loss in a Stabilized Superconducting Monolithic Conductor Coating with High Conductive Aluminium

文中结出了多量高导铝稳定化超导monolithic导体耦合损耗的计算式。它表明使用大量稳定材的导体,在稳定材中的集肤效应将对耦合损耗有重要影响,尤其在高频段。实际上,起源于集肤效应的沿导体轴向电流损耗支配着整个的耦合损耗。这一特征与一般多芯线ac损耗理论不同,本理论计算结果与实验结果取得较好一致。

A theoretical expression is provided for the coupling loss in a stabilized superconducting monolithie conductor with a thick coa- ting of high conductive aluminium. It is shown that for a con- ductor with a large amount of stabilizer, the skin effect in the stabilize will seriously affect the coupling loss, especially at high frequencies. In fact, the loss due to the current along the con- ductor axis induced by the skin effect predominates over the coup- ling loss. The present feature in the a-c loss is quits different from that for ordinary multifilamentary wires without a large amount of stabilizer. The results show quantitative agreements with those obtained by experimental measurements.
