摘要: 设计了一种变流用的带绕式空芯变压器，分析了变压器的工作原理并详细介绍了其制作过程。该变压器主要由引线、绝缘膜、铜带和内绝缘筒组成。在电容器充电电压为2500 V的条件下，实验得到该变压器原副边电流峰值分别为5.52 kA和1.48 kA，电流上升率分别为37 A/s和138 A/s。理论分析和实验结果表明:该变压器可以有效降低脉冲功率电路对开关电流上升率的要求，从而将重复频率和稳定性能更好的晶闸管应用于脉冲大电流系统，可以大大提高系统的放电频率和寿命。Abstract: In this paper, a strip air-core pulse transformer is designed to convert the current. And, how it works and the process of making iselaborated in detail. The transformer contains leads, insulator, copper strip and supporting core. Under the conditions of the charging voltage 2500 V, 5.52 kA and 1.48 kA peak current of primary and secondary windings are obtained, and correspondingly, the current rising rate is 37 A/s and 138 A/s. It is supported by analysis and experiment that the transformer can reduce the requirement of the rising rate of the switching current effectively. So, the thyristor can be used in the pulse current system which has a high current rising rate and improve its performance on repetition and stability.
