FZW28-12 Outdoor AC High Voltage Boundary Vaccum Load Switch
Usage Environment:
The FZW28-12 series outdoor AC high voltage boundary vacuum load switch is designed for use in outdoor three-phase AC power distribution systems with a rated voltage of 12 kV and a rated frequency of 50 Hz. It is suitable for application in substations, industrial and mining enterprises, urban areas, and agricultural networks. This load switch is ideal for protecting and automating city and agricultural network distribution systems, and is well-suited for environments requiring frequent operations.
Product Features:
1. Reliable Operation: Designed to switch load currents and close short-circuit currents, ensuring reliable performance in various distribution scenarios.
2. Two-Part Construction: Consists of the FZW28-12 vacuum load switch and a controller, electrically connected via an air socket and an outdoor sealed control cable.
3. Effective Detection: Capable of accurately detecting zero-sequence current and phase-to-phase short-circuit currents, suitable for distribution systems with different neutral grounding methods.
4. Versatile Application: Can be used in a wide range of applications, including substations, industrial and mining facilities, urban areas, and agricultural networks.
Precautions:
1. Installation and Connection: Ensure correct installation and electrical connection of the load switch and controller. Proper alignment and sealing of the control cable and air socket are essential for reliable operation.
2. Environment Considerations: The load switch should be protected from severe environmental conditions that could impact its performance. Regular inspections are recommended to maintain its operational integrity.
3. Operation Safety: Follow safety protocols during operation to avoid issues caused by incorrect handling or electrical faults.
4. Maintenance: Perform routine maintenance and inspections to ensure the load switch and controller function correctly and effectively. Address any performance anomalies promptly to prevent operational disruptions.
