Measurement of the Electron Temperature for Air Arc in Long Gap

摘要：

Based on the spectrum diagnosis principle for plasma radiation of air arc, the arc films in long gap were taken by the high-speed image sampling system with the color CCD camera added the interference filters, being saved as the uncompressed BMP files. With the numerical image process technology, the pixels at character wavelengths were reverted to the radiation strength. And then the radial distribution of arc radiation was gotten by Abel transform. The electron temperatures were calculated by the colorimetric method of the relative radiation strength at two different wavelengths. Test results show that the temperature measurement method for arc plasma is valid for long arc in opening air with some meters, providing an important plasma parameter to study the micromechanism of air arc in long gap.
