According to the statistics of the "2006 High Voltage Switch Industry Yearbook", in the medium voltage field, vacuum circuit breakers account for 97.9% of 12kV circuit breaker products, and vacuum circuit breakers account for 77.95 per cent of 40.5kV circuit breaker products. my country has entered the ranks of major vacuum circuit breaker countries after the United States, Germany and Japan. With the improvement of medium voltage vacuum circuit breaker technology, vacuum circuit breakers are developing in the direction of miniaturization, intelligence, maintenance-free, high voltage, low voltage, special specialization (such as: long-life low overvoltage special circuit breakers for metallurgy and steelmaking, on-board switches and railway phase switches for electrified railways, plateau vacuum circuit breakers, explosion-proof switches for mines, etc.), and multifunctionality. Among them, the research and development of miniaturized and highly reliable products is a long-term topic of product development. To achieve the miniaturization of vacuum circuit breakers, it is necessary to ensure the reliability of all components and accessories while achieving their miniaturization, and vacuum interrupters are no exception. As the demand for miniaturization of switchgear becomes stronger and stronger, the full-duty large-volume products developed in the 1980s and 1990s are no longer suitable for cities, subways and modern agriculture where land prices are as expensive as oil. Miniaturized and highly reliable switchgear with external insulation protection must be used. The sealed vacuum circuit breaker is in line with the trend of market development.
The reason why vacuum circuit breakers are so brilliant is inseparable from the continuous progress of vacuum circuit breaker technology. The sealed vacuum interrupter and its Embedded Pole technology are the embodiment of the great progress of vacuum circuit breaker technology.
