摘要：In order to satisfy the application requirement and promote environment friendly switchgear development, a vacuum degree online detection method based on laser induced breakdown spectroscopy (LIBS) for vacuum circuit breaker is proposed in this paper. A pules laser with 8mJ energy, 1064nm wavelength, 8ns duration is used to bombard the shield material and then induce plasma, the plasma light is collected by spectrometer. H I at 656.1nm, O I at 777.2nm and 777.4nm of the ambient air are analyzed, preliminary results indicate the spectral lines intensity change with pressure and the minimum detected pressure can lower than 10(-3)Pa with good resolution ratio. This is a hopeful method to solve the tough problem of vacuum degree online detection of vacuum circuit breaker.
