Customization Scheme of GGD Type Switchgear Cabinet by Wankong Electric

I. Analysis of Customization Requirement Adaptation

1. Adaptation to Industry Characteristics

- **Load Characteristics**: For the starting impact of motor-type loads (such as paper-making machines and fans) in the paper products industry, configure D-type curve circuit breakers.

- **Process Requirements**: Reserve 15% of the busbar capacity to meet the equipment expansion requirements, and support independent control of multiple circuits.

2. Enhancement of Environmental Adaptability

- **Protection Upgrade**: The cabinet body adopts an IP66 protection structure, equipped with double sealing rubber strips and dust filters.

- **Heat Dissipation Optimization**: Add a temperature sensor + intelligent heat dissipation fan (automatically starts at 45°C), and control the temperature rise inside the cabinet to be ≤ 20K.

 II. Design Scheme of the Electrical System

1. Main Circuit Configuration

- **Busbar System**: Adopt 80×10mm copper busbars, with tin-plating treatment, and the rated current is 3150A.

- **Incoming Line Scheme**: Configure universal circuit breakers (Schneider NSX or Chint NA series are optional).

- **Outgoing Line Configuration**: Use modular drawer units for each branch circuit, supporting hot-swappable replacement.

2. Intelligent Monitoring System

- **Core Configuration**: Integrate intelligent power meters (supporting Modbus RTU protocol).

- **Monitoring Functions**: Monitor voltage/current/power factor/harmonic content in real time.

- **Protection Functions**: Multi-level protection against overvoltage/undervoltage/phase loss/overload.

III. Structural Optimization Design

1. Cabinet Improvement

- **Material Upgrade**: 2.0mm galvanized steel plate + electrostatic powder spraying treatment, and the salt spray test is ≥ 1000 hours.

- **Seismic Design**: Adopt a three-dimensional reinforcing rib structure, and pass the IEC 60068-2-6 vibration test.

2. Operational Convenience

- **Humanized Design**: The cabinet door can be opened at an angle of 135°, and LED lighting inside the cabinet is configured.

- **Identification System**: Use silk-screened markings in both Chinese and English, and schematic diagrams are provided for key operation points.

IV. Production and Manufacturing Standards

1. Process Specifications

- **Welding Process**: Automatic welding by robots, with the weld seam uniformity of ± 0.2mm.

- **Spraying Process**: Adopt the phosphating-passivation process for pretreatment, and the coating thickness is 60-80μm.

2. Detection Standards

- **Electrical Tests**: Power frequency withstand voltage of 4200V for 1 minute, and insulation resistance ≥ 100MΩ.

- **Mechanical Life**: The operation times of the drawer unit are ≥ 10,000 times.

V. Delivery and Service

1. Transportation Scheme

- **Packaging Scheme**: Detachable frame + anti-vibration foam filling, meeting the moisture-proof requirements for sea transportation.

- **Logistics Guarantee**: Transport through DHL international express delivery, and provide full-course GPS tracking.

2. After-sales Service

- **Response Mechanism**: Provide 7×24-hour technical support and promise on-site service within 48 hours.

- **Training System**: Provide operation manuals (in both Chinese and English) + online video tutorials.

This scheme achieves the following improvements based on the standard GGD cabinet:

1. Enhancement of environmental adaptability: It can withstand an environment with a high temperature of 50°C, a humidity of 80%, and a dust content of 1000mg/m³.

2. Upgrade of intelligent operation and maintenance: It supports remote monitoring via a mobile phone APP, and the accuracy rate of fault early warning is ≥ 95%.

3. Optimization of installation efficiency: Adopt a modular pre-wiring design, reducing the on-site installation time by 40%.

If you need to adjust specific parameters or add special functions (such as explosion-proof design), please provide detailed requirement descriptions.
