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32.6μs。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.
