摘要

为探究不同条件下的放电特性

介绍了脉冲放电震源的原理和发展

以及一种既可实现电弧放电又可实现电晕放电的脉冲放电震源。实验平台由脉冲震源系统、电压电流测量单元、数字示波器、地震探测系统组成。在此基础上

进行了不同电压、不同电极间距条件下、不同激发位置条件下的电弧放电与电晕放电实验

观察了放电通道电阻和放电功率在时间域的变化趋势。通过地震探测系统检测了不同条件下电弧放电与电晕放电的地震波强度。通过分析发现:在电晕放电后期

电流很小

电容依然有k V级的电压

此电压通过迅速增大的等离子通道电阻而缓慢释放;电弧放电存在着明显的预击穿时间

电压越高

预击穿时间越短

反之越长

但具有随机性。

Abstract

In order to explore the discharge characteristics under different conditions

we first summarize the seismic source

especially the principle and development of pulse discharge source

and then introduce a pulse discharge source which can realize both the arc discharge and the corona discharge. Moreover

an experimental platform was set up

which consisted of a pulse source system voltage and current measurement unit

a digital oscilloscope

seismic detection system. Thereby

we experimentally research and summarize the arc discharge and corona discharge under different voltage

different electrode

different distance

and different excitation position. By using the Origin Pro 9 data analysis software

the change tendency of discharge channel resistance and discharge power in time domain was observed. Seismic intensity of arc discharge and corona discharge under different conditions were detected by the seismic detection system. Through the analysis and comparison

the characteristics of corona discharge and arc discharge were found.
