摘要

为研究不同射流体积流量和放电电压下滑动弧放电的电信号特征和电弧运动规律

对3种不同几何结构的电极进行了大气压交流滑动弧放电的电信号测量和图像拍摄。结果表明:滑动弧放电过程中存在两种滑动模式

即稳定电弧滑动（A-G）和击穿伴随滑动（B-G）;两者在电信号特征和电弧运动形态上存在明显不同

并受来流体积流量、放电电压、电极结构的影响;流场环境对电弧的形态及发展过程影响显著

随着射流体积流量的减小

滑动弧放电向A-G模式发展

体积流量越小

电弧滑动范围越大

周期也越大;对A型电极

当体积流量小于33.3 L/min后

A-G模式放电占比超过66%。

Abstract

In order to study the electrical characteristics and arc gliding rules of gliding arc discharge under different flow rates and voltages

we investigated the atmospheric pressure AC gliding arc discharge by adopting electrical and image measurements for three kinds of electrode geometrical structures. The results show that there are two gliding modes in the discharge programs

the Steady Arc Gliding（A-G） mode and the Breakdown Gliding（B-G） mode. There exist significant differences in electrical characteristic and arc gliding form between them

and they are affected by the flow rate

discharge voltage

and electrode structure. The arc form and its development process are significantly influenced by flow field circumstance. The arc form tends to the A-G mode with the decrease of flow rate

the smaller the flow rate is

the greater gliding range and period are. A-G mode discharge accounts for more than 66% for A-type of electrode when flow rate is less than 33.3 L/min.
