ZW32-12(F) Series High Voltage Vaccum Circuit Breaker With Controller Manual/Automatic Stainless Steel Sectionalizer
Product Description:
ZW32-12 outdoor AC high-voltage vacuum circuit breaker is an outdoor distribution equipment with a rated voltage of 12kV and a three-phase AC frequency of 50Hz. It is mainly used for breaking and closing the load current, overload current, and short circuit current in electronic systems. It is suitable for protection and control in substations and industrial and mining enterprise distribution systems, as well as for frequent operations in rural power grids. It can also be used as a sectional switch for power grid operation. After installing a controller, it can achieve distribution network automation.
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.High-voltage vacuum circuit breaker: It adopts vacuum arc extinguishing technology and has good breaking performance and strong arc extinguishing capability. It can reliably interrupt load currents, overload currents, and short circuit currents.
2.Outdoor design: It is suitable for outdoor environments and has good weather resistance and protection performance, allowing it to operate normally under various harsh weather conditions.
3.Rated voltage and frequency: It is suitable for distribution systems with a rated voltage of 12kV and a three-phase AC frequency of 50Hz, meeting the corresponding power requirements.
4.Protection and control functionality: It is mainly used for load protection and control in substations and industrial and mining enterprise distribution systems. It can effectively protect the safe operation of power equipment and systems.
5.Rural power grid application: Due to the frequent operations in rural power grids, this circuit breaker is widely used and can be used as a sectional switch and for distribution network automation in rural power grids.
Condition:
1.Altitude of not more than 2000 meters;
2.Ambient air temperature: -45 ° C ~ + 40 ° C. Daily temperature difference: 25 ° C;
3.Wind speed not more than 35 m / s
4.No flammable, explosive dangerous chemical corrosion and violent vibration places.
