Honle ZW3M-12 Series High Voltage Fast Permanent Magnet
Vacuum Circuit Breaker

Product Description

Product detail

Model ZW3M-12 outdoor high voltage fast permanent magnet vacuum circuit breaker is an outdoor distribution vacuum circuit breaker with rated voltage 12kV and three-phase AC 50Hz. It is a new generation of outdoor column Vacuum Circuit Breaker developed to meet the demand of smart power grid, and has the ability to break the short-circuit current several times. It can be used as 10kV side outlet of substation and post switch of distribution network. It is the first equipment to realize intelligent, automatic and small substation of distribution network.

Using conditions

1. Ambient temperature: no higher than +70ºC, no less than -40ºC;
2. Relative humidity of air: the daily average is not more than 95%, the monthly average is not more than 90%;
3. Altitude: not exceed 2000m;
4. Wind pressure: no more than 700Pa (equivalent to 34m/s wind speed);
5. Pollution grade: lV class (creepage distance ≥31mm/kV);
6. Ice thickness: no more than 10mm;
7 earthquake intensity: no more than 8 degrees;
8. Installation place: there should be no fire, explosion danger, serious pollution, chemical corrosion and violent vibration, etc.

Main Function
 

Protection: With three-stage voltage locking direction overcurrent protection, reverse time overcurrent protection, zero sequence protection, acceleration protection, overload protection, low-frequency load shedding, low-voltage disassembling and three-phase triple reclosing and other functions.

Measurement: three-phase Voltage, current, power factor, frequency, etc.

Control Function: automatic reclosing, local control and remote control can be set.

Communication function: standard RS232, RS485 or Ethernet interface, support optical fiber, distribution network carrier, wireless, twisted-pair communication mode, GPRS SMS or communication, etc.

Other functions: local display, parameter setting, fault recording and alarm, etc.
