摘　　要：介绍了一种等离子体电弧的多波长光谱诊断方法。利用一个CCD多通道光谱仪测得Ag/LaFe1-xNixO3-δ银基触点电弧的扫描多波长光谱。应用该光谱诊断方法研究了电弧等离子体中活性粒子及输入功率、通断频率和触点间距等工作参数对电弧的影响,确定了Ag/LaFe1-xNixO3-δ银基触点材料最有利的工作条件。这种非侵入式光谱诊断,为触点材料性能检测提供了一种有效的诊断方法。A CCD multi-channel spectroscopic instrument was used to measure the spectrum signal of the arc plasma, and the multi-wavelength spectrum for Ag/LaFe1-xNixO3-δ contact was obtained. Using this Spectroscopy diagnostics, the influences of the input power, the frequency and the gap of contact on arc plasma were investigated. The best work condition for Ag/LaFe1-xNixO3-δ contact material was found. The results will provide the testing of the contact material performances with an effective diagnostics way .
