大气压交流旋转滑动弧的放电特性
Characteristic of Atmospheric Pressure AC Rotating Gliding Arc Discharge
摘要
Abstract
In order to study the effects of flow rates and voltages on electrical characteristics and arc gliding rules of rotating gliding arc discharge,the atmospheric pressure AC rotary gliding arc discharge was investigated 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 gas volume flow rate and discharge voltage.The arc form and its development process are significantly influenced by flow field circumstance and discharge voltage.With the increase of gas volume flow rate,the arc form tends to the A-G mode.For E-1 type electrode,the arc gliding period is smaller (9 ms) and the arc rotating speed of export section is larger (11 m/s) when the gas volume flow rate is greater (77 L/min).With the increase of voltage,the arc discharge mode develops from B-G mode to A-G mode,and the arc rotating speed of export section becomes larger.The experimental results are valuable for revealing the mechanism of atmospheric pressure AC gliding arc discharge.关键词
