摘要

为了准确把握电弧放电电阻的大小

提高等离子体合成射流的能量利用率。进行了三电极尖尖放电的实验

通过改变电极间隙、环境气压、电容、电压

得到电弧电阻的大小以及放电效率、电弧电阻和放电形态随参数的变化。结果显示:大气压条件下

随着放电初始电压的增大

放电效率和电弧电阻逐渐降低;大气压条件下

对于同一电容能量（≥250 m J）

电弧电阻不会随着电容值的变化而变化;高气压条件下（>50 k Pa）

电容越大

电弧电阻和放电效率越高;增大电极间隙

可以增大电弧放电的电阻和放电效率。随着气压降低、电压增大或电极间隙增小

放电区域面积会增大。

Abstract

In order to calculate the resistance of arc discharge exactly and enhance the energy utilization of plasma synthetic jet actuator（PSJA）

we experimentally investigated the sharp discharge of three-electrode. The values of arc resistance and trend of discharging efficiency

arc resistance

and discharge pattern were obtained by changing parameters such as the electrode gap

air pressure

resistor and voltage. Results show that

at the atmospheric pressure

with the increase of initial discharge voltage

the discharge efficiency and arc resistance decrease gradually. At the atmospheric pressure

the arc resistance keeps unchanged regardless of capacitance for the same capacitor energy（≥250 m J）. At high air-pressure（>50 k Pa）

the arc resistance and discharge efficiency become bigger with the increase of capacitance. When the air pressure becomes lower

the initial discharge voltage becomes bigger

or the distance of electrodes becomes smaller

and the arc resistance and discharging efficiency will be bigger.
