A container substation is a complete power distribution device that combines high-voltage switchgear, distribution transformers, low-voltage switchgear, electricity metering devices, and related auxiliary equipment according to a scientific wiring scheme. It is pre-manufactured, assembled, and tested in the factory, and then installed as a whole in one or more sturdy, transportable container-type housings.

III. Advantages of Container Substations
The advantages of container substations are very prominent and can be summarized into the following key points:
1. Time and labor-saving in construction
The core equipment of container substations is integrated and manufactured in the factory. Once delivered on-site, only basic positioning and wiring connections are needed, significantly shortening the construction period and allowing for quick response to emergency or temporary power needs.
2. Low overall cost
It eliminates a large amount of civil engineering and on-site installation costs, requires less land, and reduces costs for land, construction, and labor, offering good economic benefits throughout its entire lifecycle.
3. Flexible and movable deployment
Container substations use standard container structures, providing excellent mobility. They can be relocated as a whole to new locations according to changes in power demand and reused, which is especially suitable for temporary projects.
4. High reliability and stable quality
Factory production ensures rigorous processes, standardized wiring, and reliable quality control. The container substation enclosures have high protection ratings, effectively resisting wind, rain, and external interference.
5. Wide range of applications
This allows them to easily adapt to densely populated urban areas, industrial parks, renewable energy power stations (solar/wind), and field operations, as well as various complex environments.
IV. Inspection and Acceptance before the Operation of Container Substations
1. Foundation and Placement:
Ensure that the concrete foundation is solid and level, higher than the surrounding ground, with good drainage to prevent water accumulation or settling under the container.
The installation location of the container substation should meet design requirements, maintain sufficient safety distance from surrounding buildings and facilities, and allow for proper ventilation and maintenance access.
2. Internal Equipment Inspection:
Cleaning and Tightening: Check all internal equipment, busbars, and terminals inside the container substation. They should be free of dust and foreign objects, and screws should be tightly fastened.
Insulation Performance: Before operation, strict insulation resistance tests must be conducted to ensure that the insulation performance of the high-voltage room, transformer room, and low-voltage room meets the standards.
Component Status: Ensure that all switches and circuit breakers are in the correct open or closed position, and protective device settings are accurate.
3. Auxiliary System Commissioning of Container Substation:
Ventilation and Heat Dissipation: Test the exhaust fans and temperature control system to ensure that heat-generating equipment such as transformers is properly cooled.
Fire Protection and Security: Check if smoke detectors and fire-fighting equipment (such as gas extinguishing systems) are functional, and ensure that door locks and security devices are reliable.
V. Inspection and Maintenance of Container Substations in Operation
1. Regular Inspections:
Regularly check the structure of the container substation to ensure there is no rust, deformation, seal aging, or water leakage.
Observe for any abnormal sounds (such as discharge noises or unusual vibrations) or unusual odors (such as burning smells) inside the container.
2. Container Substation Condition Monitoring:
Temperature Monitoring: Use an infrared thermometer to regularly measure the temperature at key points, such as switches, busbar connections, and transformer cases, to prevent overheating due to poor contact.
Load Monitoring: Closely monitor the transformer load rate to avoid long-term overloading.
3. Environmental Maintenance:
Keep the area around the container substation clear of obstacles, weeds, and debris to ensure good ventilation and heat dissipation.
Regularly clean dust inside the container, especially on insulators, bushings, and other parts, to prevent faults caused by pollution flashovers.
VI. Safety Operation Regulations for Container Substations
1. Door Lock Management of Container Substations:
The doors of the high-voltage and low-voltage rooms should be locked according to regulations, and the keys should be managed by a designated person. It is strictly forbidden for non-professional personnel to open the doors or operate the equipment without authorization.
2. Operation Sequence:
Power shutdown and energizing must be carried out strictly according to the operation procedures, following the principle of "when shutting down, first stop the load side, then the power source side; when powering up, first energize the power source side, then the load side."
When operating switches, wear insulated gloves and insulating shoes, and use qualified insulated tools.
3. Warning Signs:
The exterior of the container substation should display clear safety warning signs such as "High Voltage Danger" and "No Climbing" to remind personnel to pay attention to safety.
The stable operation of the container substation depends on the above usage precautions. Always remember that the interior is a complete distribution system and must be operated and maintained by certified electricians following regulations.
VII. Q&A on Container Substations
1. What key parameters should be considered when selecting a container substation?
Voltage Level: Specifications for high-voltage input and low-voltage output.
Transformer Capacity: Selected based on the total power load.
Operating Environment: Factors such as ambient temperature, altitude, and humidity affect equipment selection.
Internal Configuration of the Container Substation: Brands and models of high and low-voltage switchgear, protection functions, etc.
2. What is the fundamental difference between container substations and traditional civil engineering substations?
The fundamental difference lies in 'mobility' versus 'fixedness.' Traditional substations are fixed, whereas container substations are movable and can be reused assets.
3. What is key to the daily maintenance of a container substation?
Preventive inspections are crucial and include:
Observe: Structure of the container, status of indicator lights.
Listen: Sounds of transformer and fan operation.
Measure: Regularly use an infrared thermal imager to check the temperature of key connection points.
VIII. Application Scenarios of Container Substations
1. Temporary Power Supply
Container substations provide fast and flexible power supply for short-term projects such as construction sites, municipal works, temporary event venues, and emergency rescue operations.
2. New Energy Sector
As step-up stations for photovoltaic power plants or box-type transformers for wind farms, they efficiently integrate and deliver clean energy.
3. Public Facilities
Container substations are widely used for stable power distribution in public places such as city streets, parks, highways, and tunnels.
4. Industrial Power Supply
Container substations provide reliable power for various industrial parks, factories, mines, and oil fields.
Container substations have a wide range of application scenarios. Different tasks require different types of container substations, so users should choose the appropriate one based on their specific needs.
