ZW32-12 Outdoor High Voltage AC Vacuum Circuit Breaker

ZW32-12 outdoor high voltage AC vacuum circuit breaker is a three-phase AC outdoor high voltage power distribution device with the rated voltage of 12kV and the rated frequency of 50Hz, used to protect and control load current, over-current and short-circuit current in breaking and closing system in substations or power distribution system of industrial and mining enterprises below the altitude of 1000m, as well as in rural power grid and other places that need frequent operation.

ZW32-12 outdoor high voltage AC vacuum circuit breaker conforms to relative regulations of such national standards as GB 1984-2014 High Voltage AC Circuit Breaker, JB/T3855-2008 High Voltage AC Vacuum Circuit Breaker and DL/T 403-2000 Technical Requirements on Ordering 12kV~40.5kV High Voltage Vacuum Circuit Breakers.

The breaker is designed in an integrated structure that the primary electrical parts of the three-phase post is connect to the operating box into a whole.

The three-phase post structure makes the opening stable and reliable with no burning or explosion risks and requiring no maintenance. Besides, it is small, light and has long working life.

The vacuum arc extinguishing chamber is fully enclosed and sealed. It is moisture-proof and anti condensation, especially suitable for humid areas with high temperature.

The three-phase post and the current transformer are cast by epoxy resin or silicon rubber, which has the advantages of high insulation, good resistance to low through high temperature, ultraviolet and aging.

The operating system can be small-sized spring mechanism or permanent magnet mechanism. Transmission is performed directly by force with less parts needed, lower energy consumed on opening and closing and higher reliability. The operating mechanism is arranged in the sealed box, solving the problems of corrosion and improving the reliability of the mechanism.

The opening and closing of the breaker can be operated manually, electrically or remotely. Power distribution automation can be achieved by combining the breaker with the controller. The breaker can also combined with the controller of an automatic circuit recloser to form an automatic circuit recloser.

Two-phase or three-phase current transformer can be installed with the breaker so that the over current automatic tripping protection device and the intelligent controller can make information analysis.

Single-side or double-side disconnector can be added to the breaker to guarantee the safety when repairing.
