摘要
为了研究高温超导空心脉冲变压器的可行性,建立了由5个超导双饼绕组组成的空心脉冲变压器模型。采用磁场计算与电路分析相结合的方法,即在用有限元法分析磁场并计算反映绕组间电磁耦合的电感矩阵的基础上列写电路方程,分析了两种不同的绕组联接方式。在理论计算的基础上,制作了由5个高温超导双饼绕组组成的实验用空心脉冲变压器。在实验变压器二次绕组短路的情况下进行了冲击试验。由于受到环流的影响,实验结果部分与期望值相符,对高温超导空心脉冲变压器的设计具有一定参考意义。
In order to study the feasibility of the high temperature superconducting （HTS） air-core pulse transformer, an air-core pulse transformer model with five superconducting double-pancakes is built. In this paper, two different connected schemes are studied by the method of combining magnetic field calculation with circuit analysis. Based on the calculation, an air-core pulse transformer is made with five HTS double-pancakes winding for the experiment. An impact test is done with the secondary winding short-circuited. For the circulating current, the experimental results partially match the expected results, which gives some references for the design of the HTS air-core pulse transformer.
