High Efficiency Electrical Circuit Sectionlizer With Intelligent Controller ZW32 Series Vacuum Circuit Breaker
Product Description:
This outdoor high voltage vacuum circuit breaker is the rated voltage of the three-phase ac 50HZ outdoor distribution equipment, its rated current is 630A~1250A,short-current is 20kA.It mainly used forloading current,overcorrect and short current which use cut-off and close-open electricity system.
It is suitable for industrial and mining establish company while its aim is to protect and control the system and easy to suit the rural and some frequent operation place.
Controller Introduction:
1.Advanced Communication and Remote Monitoring: The ZW32-12 vacuum circuit breaker is equipped with a 485/232 communication interface, allowing for seamless integration into monitoring systems. It can also be connected through optical fiber or wireless communication for remote monitoring. This enables real-time monitoring of the circuit breaker's status, performance, and fault conditions, facilitating proactive maintenance and efficient troubleshooting.
2.Acceleration Function after Reclosing: In the event of a permanent fault, the ZW32-12 circuit breaker features an automatic acceleration tripping function. This means that if the fault persists after reclosing, the circuit breaker will automatically trip with increased speed, providing enhanced protection against persistent faults and minimizing potential damage to the system.
3.Adjustable Reclosing Delay Time: The ZW32-12 circuit breaker allows for adjustment of the reclosing delay time. This feature provides flexibility in configuring the reclosing operation based on the specific requirements of the power system. It enables customization to optimize the system's response to different fault scenarios and improve overall system reliability.
4.Anti-Misoperation Design and Anti-Jump Function: The ZW32-12 circuit breaker incorporates an anti-misoperation design for the jump closing circuit. This design prevents accidental or unintended closure of the circuit breaker. Additionally, it includes an anti-jump function, which ensures that the circuit breaker remains in a stable closed position, reducing the risk of sudden tripping due to external factors.
5.Fault Discrimination with Zero-Sequence Current: The ZW32-12 circuit breaker is equipped with the ability to distinguish between in-zone and out-of-zone faults using zero-sequence current analysis. This allows for accurate fault discrimination, enabling faster and more precise fault isolation and minimizing the impact on the power system.
6.Remote Control Switch for Misoperation Prevention: The ZW32-12 circuit breaker incorporates a remote control switch with a specific design to prevent misoperations. This feature ensures that remote operations are carried out safely and reduces the risk of accidental tripping or unintended actions.
Feature:
1.Rated Voltage and Current: The circuit breaker is designed for three-phase AC systems with a rated voltage suitable for outdoor distribution equipment. It operates at a frequency of 50Hz and has a rated current range of 630A to 1250A. This higher current rating makes it suitable for applications where higher power loads are involved.
2.Short-Circuit Capability: The circuit breaker has a high short-circuit current rating of 20kA. This means it can effectively interrupt and handle fault currents of up to 20,000 Amperes, providing reliable protection against short circuits and limiting potential damage to the electrical system.
3.System Protection and Control: The primary purpose of this circuit breaker is to protect and control the electrical system. It is designed to interrupt the flow of current during overcurrent conditions, such as overload or short circuit events. By cutting off the current, it helps prevent damage to the equipment and ensures the safety of the system.
4.Outdoor Application: This circuit breaker is specifically designed for outdoor use, making it suitable for applications in various outdoor distribution systems. Its robust construction and protective enclosure allow it to withstand environmental factors such as weather conditions, dust, and moisture.
5.Industrial and Mining Applications: The circuit breaker is well-suited for industrial and mining establishments where reliable and efficient power distribution is crucial. Its high current rating and robust design make it suitable for handling the power demands of heavy machinery and equipment commonly found in industrial and mining operations.
6.Rural and Frequent Operation Environments: The circuit breaker is easy to install and operate, making it suitable for rural areas and locations that require frequent operation. Its user-friendly design and reliable performance ensure smooth operation and maintenance even in challenging environments.
