Development of subnanosecond high-voltage pulsed source

本文对一种以亚纳秒高压脉冲放电管为主要元件的脉冲产生电路进行了计算和试验研究,给出了电路的结构参数及选取原则。实验表明所研制的高压脉冲发生电路可产生上升时间小于500ps,幅值不低于4kV的亚纳秒高压脉冲信号,并且具有放电稳定、重复性好、频谱范围广的特点,可作为研究GIS和电力变压器中局部放电信号超高频特性用的信号源。

This paper presents a pulse circuit using a subnanosecond discharge tube. Through calculation and test research, the amplitude, half-width and rise time of the pulse are given. The paper also gives the structure parameters and principle of selecting the elements of the circuit. The lab test indicates that the pulse signal it produces is steady, with wide spectrum and has good repeatability. The rise time of pulse signal is less than 500ps, half-width is less than 1 ns and amplitude is larger than 4KV. It can be used as the PD source in the study of propagation characteristic in the UHF PD measuring for power transformer and GIS.
