How to Use Electricity in Container Houses

The electricity usage in container houses mainly relies on the integrated power distribution system inside, which is powered by mains electricity or power generation equipment, and is equipped with comprehensive electrical facilities to ensure safety and functionality.

I. Core Power Supply Methods

1. Mains Electricity Connection
   Container houses are typically connected to mains electricity through three-phase power sources. The distribution box introduces mains electricity and distributes it to internal loads. The design of the power distribution system must consider three-phase balance to ensure the stable operation of equipment such as air conditioners, lighting, and fans. For example, the input of an AC distribution integrated box is derived from the AC side power of an energy storage converter, enabling efficient distribution of electrical energy.

2. Power Generation Equipment Supply
   In scenarios without mains electricity or during emergencies, container houses can integrate generator sets. The power generation station uses a container as a carrier, equipped with generator sets, fuel tanks, control systems, etc. The appropriate power unit is selected based on electricity demand, and the operating environment is optimized through noise and dust prevention systems.

II. Key Electrical Facilities

1. Energy Storage and Conversion System
   If energy storage functionality is required for container houses, battery packs, battery management systems (BMS), and energy storage inverter systems can be configured. The battery pack stores electrical energy, the BMS monitors battery status, and the inverter system converts direct current to alternating current for daily use.

2. Safety Protection System

   • Grounding System: All grounding posts must be kept clean and welded to the container body at the same potential to ensure electrical safety.
   • Lightning Protection System: Lightning protection devices are installed on the roof and connected to the grounding bar through flat or round steel grounding strips, complying with the requirements of the "Code for Design of Lightning Protection of Buildings" (GB 50057).
   • Fire Protection System: Equipped with fire extinguishers, smoke detectors, and other equipment to respond to fire risks.

III. Electrical Equipment Configuration

1. Lighting System
   Explosion-proof fluorescent tubes are used, with control switches installed near the door and emergency lighting provided. Emergency lighting must meet the standards of the "Code for Design of Fire Emergency Lighting and Evacuation Indicating Systems" (GB 17945—2010), automatically activating upon power failure and providing sufficient illumination time.

2. Temperature Control and Ventilation
   The ventilation system regulates internal temperature through air conditioners and fans to prevent moisture and mildew. Electrical wiring must use flame-retardant cables with independent insulation and sheath layers, with a long-term operating temperature of no less than 105°C to ensure safety.

IV. Design and Construction Specifications

1. Electrical Equipment Layout
   Must comply with national standards to avoid short circuits and electric leakage accidents. For example, cables are identified with different colors, and the insulation layer has a withstand voltage value one level higher than the actual voltage.

2. Insulation and Protection
   Insulating mats (with an insulation voltage of ≥5kV) are laid in the aisles, and non-functional conductors such as metal casings inside the container must be connected to the grounding copper bar to form a reliable equipotential.
