摘要: 介绍了200 kV水介质高压脉冲延时线的基本设计参数，阻抗为23.4 Ω，电长度为300 ns；分析了该延时线的耐压特性，并对其传输脉冲幅度衰减率进行了估算。加工了一套高压脉冲延时线装置，并进行了实验研究。实验中，利用Blumlein线产生两路高压方波脉冲输出，一路经高压电缆-延时线-高压电缆到匹配负载，另一路经过高压电缆到匹配负载，两负载上的脉冲等效认为是延时线的输出脉冲和输入脉冲。实验结果表明，该延时线工作电压大于200 kV，输入方波脉冲前沿为30 ns，输出方波脉冲前沿增加到34.5 ns，方波脉冲幅度损耗率为1.8%。Abstract: This paper introduces the basic characteristic parameter of 200 kV water dielectric high voltage pulse delay-line, whose characteristic impedance is 23.4 Ω and electrical length is 300 ns. It analyzes breakdown characteristic of the delay-line and estimates height attenuation rate of the pulse transmitted by the delay-line. An experiment equipment of high voltage pulse delay-line has been designed and machined, and the experiment research has been made. In the experiment, Blumlein line generated the high voltage pulse which was transited by two paths. One path is from high voltage cable to delay-line to high voltage cable to matched load and the other path is from high voltage cable to matched load. The pulses from the two loads are regarded as the output pulse and input pulse of delay-li
