Zero-Sequence Sensors Pole Mounted Circuit Breaker With Intelligent Controller Matching With Outdoor Hookstick
Product Description:
The ZW32 series Pole Mounted Circuit Breaker is an advanced type of circuit breaker that incorporates permanent magnet technology and intelligent control features. This innovative design offers several advantages over traditional circuit breakers:
Permanent Magnetic Technology: The circuit breaker utilizes permanent magnets instead of traditional electromagnets for its tripping mechanism. Permanent magnets provide reliable and consistent magnetic fields, resulting in faster and more precise tripping action when a fault or overload is detected. This improves the overall performance and responsiveness of the circuit breaker.
The circuit breaker is equipped with intelligent control features, such as microprocessors and sensors, which enable advanced monitoring and analysis of electrical parameters. The intelligent control system continuously monitors current, voltage, and other relevant parameters, allowing for real-time fault detection, accurate trip coordination, and improved system protection.
The combination of permanent magnetic technology and intelligent control enhances the safety and reliability of the circuit breaker. The precise tripping action ensures rapid interruption of faulty currents, minimizing the potential for damage to electrical equipment and reducing the risk of electrical hazards. The intelligent control system provides advanced fault diagnosis and self-testing capabilities, enabling proactive maintenance and reducing downtime.
The pole mounted circuit breaker is designed to optimize energy consumption. The precise tripping action ensures efficient interruption of faulty currents, reducing energy wastage. The intelligent control system also enables power monitoring and load management, facilitating energy optimization and improving overall system efficiency.
The use of permanent magnets and advanced control technology allows for a more compact and lightweight design compared to traditional circuit breakers. This makes installation and maintenance easier and more convenient, particularly in space-constrained
GW9-10 series hookstick switch is an electrical switch that is designed to isolate a section of an electrical network or system from the rest of the system for maintenance or repair purposes. It is typically used in high voltage power transmission and distribution systems.
The switch is designed to open and close under normal or abnormal conditions, such as a fault or overcurrent. When the switch is open, it physically disconnects the section of the system from the rest of the network, preventing the flow of electricity to that section.
High voltage disconnect switches are typically designed to operate at voltages between 600 volts and 765,000 volts, and they can be operated manually or automatically. They are typically installed in substations or on power poles, and they are an important component of the electrical grid infrastructure.
Double effect of using when GW9-10 series isolator swich can be used with the vacuum circuit breakers.
Controller Introduction:
1.Advanced Communication and Remote Monitoring: The ZW32-12 electrical sectionalizer 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 electrical sectionalizer 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 electrical sectionalizer 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 electrical sectionalizer 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 electrical sectionalizer 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 electrical sectionalizer 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.
Application:
1.Substations: It is commonly used in both indoor and outdoor substations for protection and control of medium-voltage power distribution. The vacuum circuit breaker ensures reliable interruption of fault currents, overload currents, and load currents, safeguarding the substation equipment.
2.Industrial and mining enterprises: The ZW32-12 vacuum circuit breaker is employed in the distribution systems of industrial and mining enterprises to protect motors, transformers, and other electrical equipment from overcurrents and short circuits. It helps maintain the stability and safety of the power supply in these facilities.
3.Rural power grids: Due to its ability to withstand frequent operations, the vacuum circuit breaker is suitable for application in rural power grids. It can be used as a sectional switch, allowing for efficient segmentation of the power grid. Additionally, when equipped with a controller, it enables automation of the distribution network, improving the reliability and efficiency of the rural power system.
4.Commercial buildings: The vacuum circuit breaker is also utilized in commercial buildings for power distribution and protection. It ensures safe and reliable operation of electrical systems, preventing damage to equipment and minimizing downtime.
Advantage:
1.Small Size: The device is designed with a compact form factor, allowing for easy installation in limited space environments. Its small size makes it suitable for applications where space is a constraint.
2.Light Weight: The device is lightweight, which simplifies transportation and installation. It reduces the physical burden during handling and makes it easier to mount or integrate into existing systems.
3.Maintenance-Free: The device is designed to require minimal maintenance. It is built with durable components and optimized for long-term reliability, reducing the need for frequent inspections or replacements. This feature saves time and resources on maintenance activities.
4.Anti-Condensation: The device incorporates measures to prevent condensation. It includes protective features such as sealing or insulation to minimize the risk of moisture build-up. This helps maintain optimal performance and protects internal components from potential damage caused by moisture.
