| 摘 要： | 通过对并联超导带材和并联超导绕组的实验研究,分析了直流通流时并联超导支路的电流分布特点,指出当各支路均处于超导态时,电流分布主要取决于接头电阻,当某支路接近失超临界点时,电流分布存在自调节机制,这有助于提高超导支路的整体通流能力。文中还详细分析了电流自调节机制出现的条件和可调节的程度。

| Abstract: | This paper analyses the current distribution based on the experiment of superconductor tapes and superconductor coils in parallel connection, and points out that the current distribution depends on the joint resistance. The coils will self-adjust the current among branches when one branch is near the quench point, and this effect is useful to enhance the current capacity of superconducting circuit. The paper also analyses the condition of self-adjust and the extent in detail. |
