摘要:
为了研究微间距气体放电特性机理,在大气压环境下,采用?#21496;?#23494;距离控制仪器进行电极间距为1~ 100 μm的气体放电实验,得出了电极间距在1~100 μm范围内的击穿电压,绘制了击穿电压曲线并?#33268;?#20998; 析了1~5 μm间距下击穿电压背离巴申曲线的原因。运用Fowler?Nordheim理论验证了在电极间距小于5 μm 时,气体放电过程由场致电子发射主导,并通过分析1~5 μm间距内场强,进一步?#24471;?#22330;致发射在此起主导 作用。电极间距在10~15 μm范围内时出现火花放电现象,分析认为该间距下的放电为电子崩引发的微间 隙火花放电。电极间距在15~100 μm范围内?#34987;?#31359;电压随着电极间距的增大而逐渐增大,击穿电压曲线与 巴申曲线变化趋势相同,可以用汤逊机理解释。
Abstract:
In order to study the mechanism of micro?gap gas discharge characteristics,instrument with measuring electrode distance of 1~100 μm is used to gas discharge experiments under atmospheric pressure. The breakdown voltage and breakdown voltage curve at 1~100 μm electrode gaps are obtained. The reason why the breakdown volt? age deviates from the Paschen curve at the distance of 1~5 μm is analyzed. Fowler?Nordheim theory is used to verify that the field emission dominates during discharge when the electrode distance is less than 5 μm. The electric field within the 1~5 μm gaps is analyzed to further illustrate that the field emission plays a leading role. Spark discharge occurs when the electrode distance at 10~15 μm,and it is considered that the discharge at this distance is micro?gap spark discharge initiated by electron avalanche. In addition,the breakdown voltage increases with the increase of electrode distance at 15~100 μm,and the breakdown voltage curve has the same trend as the Paschen curve.
