Full-Scenario Low-Voltage Power Distribution System for International Commercial Complexes

Project Overview

This project provides a comprehensive "end-to-end" low-voltage power distribution solution for a large-scale international commercial skyscraper. The system covers the entire power chain—from main grid intake and power quality optimization to emergency backup and terminal load control for every floor. Designed for high-density commercial, office, and safety environments, the solution focuses on three core dimensions: high-frequency maintenance, emergency reliability, and precision distribution.

System Architecture: Dual-Cabinet Synergy Mode

The project utilizes a strategic combination of GCS Draw-out Switchgear and XL-21 Fix-mounted Enclosures to meet diverse operational requirements:

1. Central Power Dispatch Hub (GCS Series)

Featuring a modular design, this series is ideal for centralized loads with numerous circuits, ensuring maximum maintenance flexibility.

Main Incoming & ATS Cabinet (ATS-MDB): Acts as the "Main Gate" for the building, integrating Automatic Transfer Switches to ensure seamless transitions between grid and backup power.

Capacitor Compensation Cabinet (MSB-02): Equipped with intelligent controllers to optimize the power factor, compensating for inductive loads (elevators, HVAC) and reducing energy loss.

Feeder Cabinets (MSB-03/04): Utilizes independent draw-out modules to distribute power precisely to various zones, allowing for isolated maintenance of a single circuit without interrupting the entire system.

2. Specialized Equipment Control Center (XL-21 Series)

Provides a high-reliability fixed layout for critical life-safety systems and heavy-duty dedicated loads.

Fire & Life Safety System: Includes distribution for the Fire Pump Room, Fire Power Supply, and Fire Security systems, ensuring uninterrupted power for mandatory safety equipment.

Ventilation & Smoke Control: Includes dedicated controls for Pressurization Fans and Dual-mode (Fire/Normal) Ventilation Fans.

Utility & Backup Support: Dedicated distribution boxes for Generator Rooms and Communication Rooms to ensure the building's backend infrastructure remains stable.

3. Terminal Distribution Network (Floor-Level)

The system extends to the final point of use through a comprehensive network of terminal units:

Floor Lighting Distribution: Manages the general lighting supply for public areas and individual floors.

Unit-Specific Lighting Boxes: Enables precise power distribution and energy metering for individual commercial tenants or office units.

Technical Advantages

Full-Link Integration: A "total solution" covering everything from incoming lines and compensation to the final terminal loads.

Multi-Level Emergency Protection: Advanced ATS configurations ensure that core circuits for fire safety, elevators, and communications remain powered during emergencies.

Maintenance-Friendly Design: The GCS modular structure allows for rapid component replacement, while the XL-21 provides a compact and durable footprint for specialized controls.

Global Standard Compliance: All systems utilize premium CHINT components and follow IEC/UL international electrical standards to meet the most rigorous overseas inspection requirements.
