12kV High Voltage Vacuum Circuit Breaker 630A/1250A Stainless Steel

Automatic High Voltage Vacuum Circuit Breaker With Zero-Sequence Sensors Intelligent Permanent Magnetic Circuit Breaker
 
 

Product Description:

ZW32-12(F) Series high voltage vacuum circuit breaker is an outdoor distribution equipment with rated voltage of 12kV and three-phase alternating current of 50Hz.It is mainly used to open and close load current, overload current and short circuit current in power system.It is suitable for the protection and control in the power distribution system of substation and industrial and mining enterprises, as well as the places where the rural power grid is frequently operated. The circuit breaker has the characteristics of small volume, light weight, anti-condensation, free maintenance and so on. It can adapt to the harsh weather conditions and dirty environment.

Controller Introduction:

1.With 485 / 232 communication interface, or through optical fiber, wireless remote monitoring; Acceleration function after reclosing;when the switch is heavy,automatic acceleration tripping in case of permanent fault;
2.Remote / manual closing to accelerate tripping, and closing reclosing: The user sends power after repairing the line, if he forgets to remove the grounding switch,should accelerate tripping.
3.Three reclosing delay time can be adjusted;
4.The jump closing circuit adopts anti-misoperation design and has anti-jump function;
5.Zero-sequence current can distinguish between in-zone and out-of-zone faults;
6.The remote control switch is designed to prevent misoperation.

Feature:

1.Three-phase pillar-type fully enclosed structure with high sealing performance.

A.Stable and reliable breaking performance, no combustion or explosion hazards; maintenance-free, small size, lightweight, and long service life.

B.Strong moisture and dew prevention performance, especially suitable for use in cold or humid areas.

C.Imported materials with good insulation performance, high temperature resistance, UV resistance, and aging resistance.

2.Efficient and reliable miniaturized spring operating mechanism.

A.The energy storage motor has low power consumption for opening and closing operations; the mechanism adopts a direct transmission method with fewer components, resulting in high reliability.

B.The operating mechanism is placed in a sealed box to effectively prevent rust and improve the reliability of the mechanism.

3.Convenient and flexible control and free combination performance.

A.It can be manually operated for breaking or electrically operated for opening and closing, as well as remotely controlled from a remote location.

B.It can be paired with an intelligent controller to achieve distribution automation or combined with a recloser controller to form an automatic recloser or sectionalizer.

C.It can be equipped with two-phase or three-phase current transformers for overcurrent or short circuit protection.

D.It can provide current acquisition signals for intelligent controllers and can be equipped with metering current transformers according to user requirements.

E.It can be equipped with a three-phase interlocking isolation switch with a built-in anti-misoperation interlocking device; it can also be installed with surge arrester pillar insulators for easy maintenance.
