A container substation is a complete set of power distribution equipment that integrates high-voltage switchgear, distribution transformers, and low-voltage distribution devices into a movable steel container according to a specific wiring scheme. It achieves an organic integration of functions such as high-voltage reception, transformer step-down, and low-voltage distribution.
I. Characteristics of Container Substations
Container substations have good technical performance and high safety, can operate unattended, and feature significant advantages such as small land occupation, short construction period, low investment, and an attractive appearance that easily blends with the environment.
II. Huaquan Power is a professional container substation manufacturer in China.
Huaquan Power Company was established in 2010. Its business spans multiple fields, including power generation equipment, new energy storage equipment, high and low voltage complete sets of equipment, and power engineering. The company has created three major brands: "HQ-POWER," "HUAQUAN," and "Huaquan." Currently, the company has developed into a strong global brand in the power industry, with cumulative global sales exceeding 1 million units.
III. Advantages of Container Substations
1. Small Footprint: Container substations are modular in design, occupying little space and saving valuable land resources.
2. Fast Construction: Container substations are prefabricated in the factory, requiring only hoisting and wiring on site, reducing construction time by over 50% and enabling quick return on investment.
3. Safe and Intelligent: Fully enclosed insulated structure suitable for harsh environments; supports automated 'four remote controls,' allowing for unmanned operation.
4. Flexible and Relocatable: Standardized container units are easy to transport, quickly assemble and disassemble, and relocate as a whole, supporting reuse.
5. Aesthetic and Harmonious: The exterior design can blend with the surrounding environment, reducing visual impact.
IV. Precautions for the installation of container substations
1. Preparations before the installation of container substations
Site and foundation: The site should be close to the load center, with high terrain and good drainage, and avoid low-lying water accumulation. The foundation needs to be made according to the design, to ensure stability and level, the error is usually no more than 5mm, and the cable channel and ground pole position are reserved.
Equipment and personnel: Before the installation of the container substation, it is necessary to check the equipment model to check whether there is any damage to the appearance and whether the accessories are complete. Construction personnel need to undergo professional training and safety disclosure and hold a certificate.
2. Key points of the installation process
Box hoisting: Container substations must use special spreaders to operate smoothly and avoid collisions. Before hoisting, the spreader should be checked, the command should be clear, and the box should be accurately placed on the foundation.
Electrical connection: cable connection is the key, it is necessary to ensure that the model specifications are in line with the design, the cable head production process is up to standard, the insulation is good, and the fixation is good. The insertion depth of the high-voltage plug-in elbow plug should be the same.
Grounding system: The grounding conductor should be copper, with a cross-section of not less than 30mm². The installation of the grounding electrode should meet the design requirements to ensure good contact with the soil, and the grounding resistance is generally not greater than 4Ω. Each grounding point should be reliably connected to the main grounding body.
3. Debugging and safety
Test and plugging: After the installation of the container substation is completed, necessary electrical tests are required. Finally, all holes in the bottom plate of the box substation need to be sealed.
Whole process safety: The construction area of the container substation should be guarded, and irrelevant personnel are strictly prohibited from approaching. During the power test operation, all doors should be locked. Operators need to dress standardly and wear qualified safety protective equipment.
V. Q&A on Container Substations
1. What are the key points for the operation and maintenance of container substations?
They should not be operated under overload for long periods, transformer oil should be checked regularly, equipment temperature should be monitored, poor conductor contact should be addressed promptly, good ventilation and heat dissipation should be ensured, and lightning protection should be in place.
2. Why is the construction period of a container substation short?
Because the equipment is prefabricated, installed, and commissioned in the factory, on-site work only requires hoisting and positioning, cable connections, and commissioning, making the entire installation and commissioning period short.
3. How is the adaptability of a container substation to its operating environment?
The box uses anti-corrosion, fireproof, and thermal insulation materials and is equipped with environmental control devices, allowing it to operate normally in harsh environments.
VI. Application Areas of Container Substations
1. Urban Public and Commercial Power: Container substations are used in residential communities, commercial complexes, office buildings, hospitals, parks, and tourist areas, meeting the demands for aesthetics, quiet operation, and reliable power supply.
2. Transportation Infrastructure: Container substations are used for subways, high-speed rail, airports, highway service areas, urban utility tunnels, and street lighting distribution, suitable for rapid deployment and space constraints.
3. Industrial and New Energy: Used for factories, mines, industrial parks, as well as the step-up and grid-connection stages of new energy power plants such as photovoltaic and wind power.
4. Temporary and Special Power Needs: Used in construction projects, large events, charging station clusters, field engineering, emergency repairs, and remote area microgrid power supply.
The compact structure, mobility, and rapid deployment characteristics of container substations make them an efficient solution for a wide range of scenarios, from fixed distribution networks to temporary power supply.
