General
 

ZW32 - 12(G)  / T Type Intelligent Outdoor High Voltage AC Vacuum Circuit Breaker (Hereinafter referred to as "Intelligent Circuit Breaker"), is an outdoor high voltage distribution switch(switchgear) equipment with 12kV rated voltage, 50Hz 3-phase AC, which is mainly used to disconnect, close electric systems load current, overload current and short-circuit current. It is suitable for use in substations and Industrial and Mining Enterprise distribution systems for protection and control. It can also be used in places requiring frequent operation such as rural power grids.
 

Intelligent Circuit Breakers conform to the technical standards of High Voltage AC Circuit Breaker (GB/T 1984-2014), High voltage AC Circuit Breaker (DL/T 402-2016), technical conditions for ordering 12kV ~ 40.5kV High voltage vacuum circuit breaker (DL/T 403-2000) and a remote terminal for Distribution Automated system (DL/T 721-2013), etc.

10. Resistance to floor drain: horizontal acceleration 0.3g, vertical acceleration 0.2g

Main Advantages

1. The overall structure is a three-phase pillar type, and the shell has good sealing performance.
2. The shell (box) adopts SUS304 non-magnetic stainless steel, which is precisely welded and polished by an imported argon arc welding machine. It has a beautiful appearance and will never rust.
3. The vacuum interrupter is connected to the operating mechanism through an insulating pull rod, with stable and reliable performance.
4. The vacuum interrupter, main electric circuit, insulation support, and other parts are poured into an organic whole by APG process with epoxy resin and encapsulated with silicone rubber, which has good anti-condensation performance and mechanical strength.
5. It adopts a high-performance miniaturized spring operating mechanism, which has a simple structure and long mechanical life and has the functions of electric, manual energy storage, and opening, and closing operation.
6. The utility model has the advantages of a novel structure, small volume, lightweight and convenient installation.
7. It can realize the functions of three-stage protection, zero sequence grounding protection, reclosing, and remote communication.
