This outdoor vacuum circuit breaker is outdoor distribution equipment with rated voltage 11KV and three-phase AC 50Hz. It is combined micro processing technology, modern network communication technology and the new switch manufacturing technology together, and has multi-protection and functions, such like overload, short circuit, quick break, earthing, reclosing, remote control and remote communication, etc. This circuit breaker is mainly used for breaking and closing the power system load current, overloads current and short-circuit current. Widely used in urban power grid as a section or contact switch, or for rural electric power distribution system of outdoor substation as a outgoing switch.
ZW32-33kV outdoor vacuum circuit breaker + recloser is a combined serialized product:
1. Combination disconnecting switch is optional for it, which can provide visible contactor for line maintenance;
2.magnetic operating system is also optional, to form complete operating functions when cooperate with vacuum arcing chamber, making the actions of open and close stable and reliable;
3.Adopts new type of composite solid insulation structure, combined the vacuum arcing chamber, main electric circuit and insulation support as an integrated solid pole column organically, completely solved the contradiction between miniaturization of vacuum arcing chamber and the requirement of external insulation;
4. Horizontal layout of bushing, transversal layout of the output and input, even in the overhead lines connection, also conducive to the access of the cable;
5. The intelligent control power supply system in the unit can ensure to provide continuous power for battery at least 24 hours, to control the switch reliable
