| 摘 要： | 介绍了螺旋线型空芯脉冲变压器的基本理论及设计中的关键技术，设计了一台高变比螺旋线型空芯脉冲变压器，此空芯变压器初级为紫铜皮沿绝缘外筒内壁螺旋绕制三匝，次级为锥形高压绕组，约1 800匝。其初级充电电压只需要几kV，因此初级开关采用可控硅，而不需要晶闸管，这样将使初级回路及初级电容体积大大减小。 对设计的空芯变压器进行了模拟计算和实验研究， 实验结果表明： 在初级储能电容充电为2 400 V时，变压器次级所接形成线负载的输出电压达到900 kV，充电时间约为32.6 μs。

| Abstract: | The basic theory and some key technologies of the air-cored transformer in design are introduced, and a helical line air-cored transformer with high turn ratio is designed. The primary winding is a 3-turn copper sheet, and the secondary winding is a conical winding with 1 800 turns. The output voltage of the transformer is simulated by Pspice, and then the experiment is done. The results of testing show that, the output voltage of the air-cored transformer is up to 900 kV, when the charge voltage of the primary capacitor is 2 400 V. |
