Vacuum circuit breakers for users to judge whether or not the vacuum tube vacuum is the frequency commonly used withstand methods, such an methods can only judge the vacuum for the serious deterioration arc-extinguishing chamber. When vacuum degrees deteriorate 10-2－10-1Pa, although not puncture voltage reduction, but have failed arc-extinguishing chamber. MS-208V type vacuum testing device used for new exciter coil, used principally discharged methods test arc-extinguishing chamber for the vacuum without demolition arc-extinguishing chamber. At the same time the use of computer for simultaneous control and data acquisition processing, arc-extinguishing chamber for on-site testing of vacuum sensitivity achieved 10-4Pa. The most prominent feature is the use of equipment new exciter coil and data processing methods for achieving a vacuum of non-demolition measurements. The apparatus is easy to use, operate and not demolition arc-extinguishing chamber higher precision measurements and testing the merits of the instrumentation is a practical, widely applicable to the power, steel, petrochemical, textile, coal, railway, the use of vacuum switches sectors.
