Operation of a super-conducting magnet requires a large current. A basic study was performed to produce a very large current ever been achieved with low power based on the fact that it does not require any voltage. This can be achieved if thesecondary winding of a transformer consists of single turn, in principle. However, the leakage flux of the transformer becomes a large problem in this case. We have developed a 3-dimensional winding shape that eliminates the leakage flux. Description of the model by the script language made it possible to use ANSYS iteratively. We found this method is very useful for variety of applications and successfully simulated the quench of super-conducting magnets.

超导磁体的运行需要大电流。基于它不需要任何电压这一事实，进行了一项基础研究，以产生曾经在低功率下实现的非常大的电流。原则上，如果变压器的二次绕组由单圈组成，就可以实现这一点。然而，在这种情况下，变压器的漏磁成为一个很大的问题。我们开发了一种三维绕组形状，消除了泄漏磁通。用脚本语言对模型进行描述，使得迭代使用有限元分析软件成为可能。我们发现这种方法在各种应用中非常有用，并成功地模拟了超导磁体的失超。
