Efficient and reliable urban power distribution solution: Compact Substation

In the field of modern power supply that pursues efficiency, flexibility and economy, the compact substation has become an ideal choice for urban power grid construction and transformation, industrial and mining enterprise power supply and temporary power use. It highly integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices into a factory-prefabricated, sturdy and sealed steel structure box. It has the characteristics of moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, and heat-insulating. It is an excellent alternative to traditional civil substations.

Why choose a compact substation?

Compact substations are widely used in a variety of scenarios due to their unique advantages:

Urban public facilities (such as street lamp power supply): The cost is significantly lower than that of traditional power rooms, and the appearance is beautiful and compact. The European compact substation can be customized with a landscape-type shell, which perfectly integrates into the urban environment and becomes a beautiful landscape.

Residential communities and parks: Small footprint, low space requirements, exquisite appearance design can be harmoniously integrated into the community or park landscape, solving the dual problems of beauty and space limitations.

Industrial and mining enterprises: The installation is convenient and fast, and the on-site construction volume is extremely small, which greatly shortens the construction period and reduces the project cost. Its high protection level ensures stable operation in complex terrain and harsh industrial environments.

Temporary construction power supply: Its excellent mobility enables it to be flexibly moved with the progress of the project, and its strong load capacity fully meets the temporary power needs of large construction sites.

Professional installation guarantee: Key points for outdoor applications
To ensure the long-term safe and reliable operation of the box-type substation outdoors, please follow the following key installation precautions:

Safe grounding: Copper conductors with a cross-section of not less than 30mm² must be used for reliable grounding. The grounding grid must have sufficient coverage and depth (recommended burial depth>1 meter), and cooperate with vertical grounding electrodes to minimize grounding resistance and provide complete lightning protection.

Site selection requirements:

1.Avoid areas with strong vibration and strong electromagnetic interference.

2.Ensure that the cable inlet and outlet meet the safe distance.

3.Choose a dry and well-ventilated location.

4.The installation foundation must be horizontal, with an inclination of no more than 5 degrees.

5.Stay away from flammable, explosive and highly corrosive substances.

Efficient operation and maintenance: Designed for fully enclosed unattended operation, it greatly saves floor space and subsequent operation and maintenance costs.

Intelligent operation and maintenance and rapid fault response
We are well aware of the importance of reliability. The box-type substation is designed for easy maintenance and provides clear fault handling instructions:

◈Overheat protection: The built-in temperature monitoring system can provide timely warnings. Regularly clean the internal dust to ensure that the heat dissipation channel is unobstructed, effectively preventing the risk of insulation aging or short circuit caused by overheating of the equipment.

◈On-load switch reliability: Select high-strength and long-life on-load tap changers, strictly control the manufacturing and installation process, and minimize failures caused by mechanical deformation, component damage or main shaft breakage.

◈Low-voltage tripping processing: Provide a systematic troubleshooting process:

Distinguish between busbar faults, line faults or switch malfunctions.

Check the protection device (pressure plate) throw-in and retraction status.

Combine protection action signals (such as overcurrent protection on the low-voltage side of the main transformer, line protection) to quickly locate the fault point.

◈Comprehensive maintenance of tripping: When a tripping occurs, our design facilitates quick maintenance:

Prioritize the inspection of the tripping switch status (energy storage mechanism, power fuse, etc.).

Analyze the protection action information (tripping on three sides of the main transformer, tripping on the low-voltage side, and tripping on the line), and accurately locate the source of the fault (internal or external lines of the equipment).

Efficiently carry out equipment inspection and line troubleshooting to accelerate the restoration of power supply.

Core of safe operation: fire prevention and explosion prevention
Safety is the lifeline of power equipment:

☉Strict load management: Avoid long-term overload operation to prevent accelerated aging of insulation.

☉Maintenance of oil-immersed transformers (if applicable): Regularly test the insulation performance of transformer oil and replace unqualified oil in time.

☉Intelligent temperature monitoring: Continuously monitor the operating temperature of the transformer (especially the temperature rise of the core) to prevent thermal aging of insulation. Strictly protect the insulation components during maintenance.

☉Reliable connection: Regularly inspect and tighten the electrical connection points to eliminate the hidden dangers of poor contact.

☉All-round lightning protection: Lightning arresters are equipped on the high-voltage side, transformer, and low-voltage side to build a complete lightning protection system.

☉Optimized heat dissipation design: Scientifically designed ventilation openings, and powerful exhaust fans are standard in key areas (transformer room, low-voltage room). The transformer room is equipped with an automatic temperature control system to ensure that the internal temperature is always within a safe range. For example, [your company name] box-type transformers use advanced temperature control fan systems to effectively guarantee operating temperatures.
