摘要
Abstract
Arc temperature is an important physical parameter to present air arc characteristics in long gap. It was measured by spectrum diagnosis, which offers foundation for secondary arc self-extinction. Based on the spectrum principle for plasma radiation of air arc, arc films in long gap were taken by the corrected high-speed image sampling system with optical pretreatment instrument. With application of the numerical image process technology and Abel transform, the plasma temperatures were gotten by means of two-color thermometry with relative radiation strength. The temperature measurement system was developed for long air arc, and the temperature distributions of arc at low current were measured. All results show that the temperature measurement method for arc plasma is valid and reliable, which provides the tool to further analyze the plasma mechanism of secondary arc self-extinction.关键词
