GGD Intelligent Low-Voltage Power Distribution System
The upgraded GGD Intelligent Distribution Cabinet integrates sensing, communication, and data analytics technologies, transforming the traditional “passive maintenance” approach into a fully intelligent system that enables real-time condition monitoring, fault early warning, and energy efficiency optimization.
GGD Intelligent Low-Voltage Power Distribution System
The GGD-Type AC Low-Voltage Switchgear Cabinet is a fixed low-voltage distribution device designed with the principles of safety, economy, rationality, and reliability. It complies with GB/T 7251.12-2013 and IEC 60439-1 standards and is widely used in indoor low-voltage distribution systems of power plants, substations, industrial and mining enterprises, and commercial buildings. It performs the core functions of power conversion, distribution, and control for motors, lighting, and other distribution equipment.
Advantages & Features
Real-Time Full-Parameter Monitoring: Equipped with wireless temperature sensors and multifunction power meters to continuously collect voltage, current, busbar temperature, energy consumption, and other data. In case of anomalies, alerts are sent via app or SMS, reducing fault response time to within 15 minutes.
Digital Operation & Maintenance Management: Devices are linked to QR-coded records, allowing instant access to manuals and operational logs. Supports local and cloud monitoring, automatically generating inspection work orders, with maintenance reminders achieving 95% accuracy.
Multi-Protocol Compatibility: Supports Modbus, MQTT, and IEC 61850 protocols, enabling seamless integration with DCS/EMS systems and interoperability with multi-brand equipment such as Schneider and ABB.
Energy Efficiency Optimization: Monitors time-segmented electricity usage and power factor, generates energy efficiency reports, accurately identifies energy-saving potential, and supports green, low-carbon operations.
Advanced Safety Features: Cable joint overheat alerts and electrical fire monitoring (integrated with smoke or water leakage sensors).
Fault Recording and Localization: Captures fault waveforms and locates issues to shorten downtime during maintenance.
Edge Computing Gateway Support: Enables breakpoint data transfer, storing data locally during network interruptions.
