Precautions for Using Container Type Substation in Cold Weather

Time：2025-12-25 15:49:59 Edit：HuaQuan Traffic Index：0

A Container Type Substation is a prefabricated substation that integrates high-voltage switchgear, transformers, low-voltage distribution equipment, and other components within a standard container.

I. Product Features of Container Type Substation
The core features of container Type Substations are 'rapid deployment, flexible integration, and reliable protection.' Essentially, they are factory-prefabricated standardized power modules.

II. Huaquan Power is China's Professional Container Type Substation Manufacturer
Huaquan Power Company was established in 2010, based in Weifang and serving the world. Upholding the corporate mission of "bringing green energy to the world," Huaquan Power's industries cover multiple fields including power generation equipment, new energy storage equipment, high and low voltage complete sets of equipment, and power engineering. The company has also built three major brands: "HQ-POWER," "HUAQUAN," and "Huaquan." Currently, the company has grown into a strong global brand in the power industry, with cumulative global sales exceeding 1 million units.
As a professional container type substation manufacturer in China, Huaquan Power relies on modular prefabrication and has standardized production processes, which can significantly shorten the cycle from order to on-site commissioning. The company is especially skilled in emergency power supply projects.
Huaquan Power achieves full-process independent production and control of container type substation, from cabinet structure and sheet metal processing to internal high and low voltage equipment integration and wiring debugging, ensuring delivery quality and consistency. The company can also design and configure according to specific project environments, space limitations, and special functional requirements, with extensive experience in non-standard solutions.
Huaquan Power has established a comprehensive service network, capable of providing timely on-site technical support and after-sales response, giving users peace of mind.

III. Advantages of Container Type Substation
The core advantages of container type substations are 'fast deployment, flexible integration, and reliable protection.'
1. Fast Deployment: Container type substations are prefabricated in the factory; on-site work only requires the foundation and wiring, resulting in a short construction period.
2. High Integration: High voltage, transformer, low voltage, and intelligent units are integrated within a standard container, saving space.
3. Flexible Mobility: Container type substations can be relocated as a whole and reused, perfectly suited for temporary, emergency, or phased projects.
4. Strong Environmental Adaptability: The container shell provides protection against dust, moisture, corrosion, and mechanical damage.
5. Intelligent and Convenient: Optional intelligent monitoring enables remote operation and maintenance.

IV.Precautions for Using Container Type Substation in Cold Weather
The key to using container type substations in cold weather is "prevent condensation, ensure startup, and maintain stable operation." The following are the main precautions and operation checklist:
1. Condensation and Insulation Faults
Phenomenon: Large temperature differences inside and outside the container type substation can cause water vapor to condense on electrical equipment surfaces, leading to tracking and short circuits.
Countermeasures: Heating and dehumidifying devices (air conditioners, electric heaters, dehumidifiers) must be operated in advance and continuously during operation to ensure the internal temperature and humidity are within the allowed range of the equipment.
2. Equipment Startup and Operation Abnormalities
Transformer: Confirm that oil-immersed transformers use low-temperature grade oils (e.g., -25°C, -30°C, -45°C); for dry-type transformers, confirm the environmental rating (e.g., -25°C).
Circuit Breakers and Mechanisms: Check that the lubricating oils (or greases) for the operating mechanisms and bearings of the container type substation are low-temperature types to prevent freezing and jamming.
Battery: Capacity drops sharply in low temperatures, which may cause abnormal backup power. Insulated boxes or heating devices should be provided, and voltage monitoring should be strengthened.
3. Container type substation and Structural Safety
Sealing Inspection: Focus on checking the seals at the container doors, cable entries, and ventilation openings to prevent wind, snow, and dust intrusion.
Material Brittleness: Metals and plastics become more brittle at low temperatures. Operations and inspections should be performed gently to avoid forceful handling.
4. Operation and Maintenance Checklist
Before Commissioning: Turn on the internal heating and dehumidifying devices of the container type substation for at least 24 hours for preheating and moisture removal.
During Operation: Increase special patrols, focusing on monitoring the internal temperature and humidity, snow/ice accumulation on equipment, and the status of heating devices.
During Operations: Avoid major operations such as switching on/off during extreme low-temperature periods.

V. Q&A on Container Type Substations
1. What should be noted about the batteries of container type substations in low temperatures?
The capacity will degrade, and insulation boxes or heating modules need to be installed.
2. What functions can the intelligent monitoring of container type substations achieve?
Remote temperature and humidity monitoring, fault alarms, energy efficiency management, and video inspection.
3. What should be paid attention to during the transportation and lifting of container type substations?
Confirm the road bearing capacity and turning radius, and use dedicated lifting points when hoisting.

VI. Application Areas of Container Type Substations
Engineering Construction: Temporary power supply for construction sites, railway and highway construction, etc.
New Energy Sector: In photovoltaic power stations and wind farms, container type substations serve as booster stations or collection units.
Industrial and Mining Enterprises: Flexible power distribution for production in mines, oil fields, development zones, etc.
Emergency Power Supply: Container type substations are used for emergency power during disaster relief, large events, or power grid failures.
Urban Distribution Network: Rapid expansion nodes when urban area loads grow quickly.

The core application area of container type substation is "temporary or semi-permanent power supply scenarios that require rapid deployment, flexible mobility, or space-saving." Users should choose the appropriate containerized substation based on their specific work needs.
