Product Introduction

Overview:

ZW51-12 Outdoor Vacuum Circuit Breaker is rated voltage of 12kV, three-phase AC 50Hz outdoor power distribution equipment, three-phase power system, which is mainly used to opening and closing, close the load current, overload current and short-circuit current in the three-phase power system. The product conforms to the standard GBl984-2003 "AC high voltage circuit breaker".

Advantage of Porduct:

ZW51-12 Outdoor Vacuum Circuit Breake is mainly composed of pillar components, operating mechanism, isolating switch, current transformer, etc., of which the disconnector and current transformer can be selected according to user needs. The product adopts fully sealed structure, integral molded casing, outdoor core-piercing current transformer and permanent magnet operating mechanism. It has the advantage of advanced and reasonable design, such as compact structure, reliable performance, no condensation and no rust. The ZW51-12 Outdoor Vacuum Circuit Breake can be configured with an intelligent control unit (FTU) to upgrade to an intelligent all-in-one switch to fully meet the needs of distribution automation.

1. Using outdoor epoxy casting process, the vacuum arc extinguishing chamber and the current transformer are poured to form an integrated solid insulation maintenance-free phase column assembly, no oil, no gas, no pollution.

2. Vertical phase arrangement, easy to install.

3. All stainless steel shell, no rust worries.

4. With permanent magnet actuation mechanism, adapt to different occasions requirements.

5. With the electronic control unit to become an intelligent circuit breaker, can achieve "four remote" monitoring.

6. CT power supply, PT power supply, solar power supply, a variety of power supply methods, safe and reliable.

Environment Condition:

1. Ambient air temperature: upper limit +40 °C, lower limit - 30 degrees Celsius (general area), - 40 degrees Celsius (alpine area)

2. Altitude: ≤ 1000m (if the altitude i has been high, the rated insulation level is correspondingly increased;

3. Wind pressure: not more than 700Pa (equivalent to wind speed 34m/s);

4. Earthquake intensity: not more than 8℃;

5. Pollution grade: IV.

6. Maximum daily temperature difference: not more than 25℃.
