ZW32-24 / 630-25 outdoor high voltage AC vacuum circuit breaker is an outdoor power distribution equipment with rated voltage of 24kV and three-phase AC 50Hz. It is the switchgear developed by our company according to the long-term plan of power system and relevant standards. All performance indexes fully meet the requirements of high voltage alternating current circuit breaker (GB1984-2003) and common technical requirements for high voltage switchgear and control equipment (GB/T 11022-1999). It has the ability of breaking and closing the load current, overload current and short circuit current in the line. It is suitable for protection and control equipment in power distribution system of substations, industrial and mining enterprises, as well as rural power grid and places with frequent operation.
1、Adopting three-phase pillar structure, it has stable breaking performance, no danger of combustion and explosion, maintenance free, touch free, small size, light weight and long service life.
2、The vacuum arc extinguishing chamber system and operation system are fully sealed in the junction with good sealing performance, which is helpful to improve the moisture-proof and anti condensation, especially suitable for the cold or humid in the environment.
3、The three-phase pillar and current transformer adopt imported high-performance outdoor epoxy resin solid insulation, which has the characteristics of high and low temperature resistance, outdoor line resistance and hang aging resistance.
4、Miniaturized spring operating mechanism, low energy consumption of opening and closing, direct drive mode, less parts and high reliability of the whole machine.
5、The opening and closing operation of the circuit breaker can be operated manually or electrically. The intelligent controller can meet the white switching function of the power grid.
