TBBZ High-Voltage Reactive Power Automatic Compensation Device

Key Features

good Operating Conditions
The High-Voltage Reactive Power Automatic Compensation Device is engineered to function repeatedly under various environmental and operational conditions:
- Altitude: Up to 1000m
- Ambient Temperature: -25°C to 55°C
- Relative Humidity: Up to 85%
- Operational Safety: The device is suitable for environments free from explosive media, corrosive gases, or conductive materials that could compromise insulation.

Advanced Compensation Capabilities
This device is designed to operate efficiently under specific voltage and current conditions:
- Capable of continuous operation at a steady-state overvoltage of 1.1 times its rated voltage.
- Can handle continue overcurrent conditions where the root mean square does not exceed 1.3 times the rated capacitor bank current.
- Utilizes vacuum contactors for capacitor switching, allowing for frequent operations without performance degradation.
- Equipped with discharge coils that ensure the residual voltage drops below 50V within 5 seconds after disconnection.

Comprehensive Protection Mechanisms
The High-Voltage Reactive Power Automatic Compensation Device integrates multiple protection features to enhance operational reliability:
- Overcurrent and Voltage Imbalance Protection: Relays or microcomputer-based protection units monitor and control capacitor group operation, ensuring stability.
- Fault Isolation: If a capacitor group encounters a fault, it can be disconnected without impacting the performance of the remaining groups.
- Fuse Protection: Each capacitor unit is safeguarded by expulsion-type fuses to prevent damage from overcurrent incidents.
