【摘要】 对于大多数超导电力装置来说,用于制冷的费用决定着整个系统的长期运行成本,电流引线漏热是低温系统的主要热负荷来源,是造成整个超导装置中静态冷量损失的主要原因。引线温度分布决定了漏热的大小,实际工程应用中常需要在给定尺寸下求解电流引线的温度分布及低温端漏热,文中介绍的松弛迭代法可迅速求解出电流引线沿线的温度分布,并推导出引线低温端漏热,由于松弛法可以通过多次迭代实现误差控制,因此,求解精确度能得到有效保证,为不同工况下电流引线优化设计提供了一种快速有效的计算方法。更多还原

【Abstract】 For most of the superconducting power devices,the long-term running cost of the whole system depends on the cooling expenses.However,the heat leakage of current lead is the main source of heat load and the primary cause of the loss of the refrigeration power.The temperature distribution determines the heat leakage.In practical engineering application,we usually need to solve temperature distribution of the current lead and the heat leakage of the low temperature end under the given size.The relaxation iteration method can quickly achieve this goal.The solving accuracy can be guaranteed effectively because the relaxation method is capable of realizing error control through multiple iterations.Therefore,it can provide an effective way of calculation in the optimal design of current lead under different running conditions.更多还原
