III. Advantages of Container Type Substations
1. Rapid deployment and high mobility: All equipment is prefabricated and tested in the factory, and after arrival at the site, it can be put into operation simply by connecting cables, greatly shortening the construction period.
2. Extremely compact structure: Container Type Substations occupy a small area, saving land resources.
3. Use of fully enclosed, insulated, sturdy containers: They are moisture-proof, dust-proof, and corrosion-resistant, capable of stable operation in harsh environments, and allow for unattended operation.
4. Economic benefits: Container Type Substations not only save on initial investment but also have operating and maintenance costs far lower than traditional solutions.
5. Modular and flexible combination: These features make later capacity expansion or functional upgrades very convenient.
IV. Precautions for Using Container Type Substations
1. Inspection Before Putting Container Type Substations into Operation
This includes checking whether the paint on the Container Type Substation is intact, whether the interior is clean, and whether all electrical installation nuts are tightened. It is necessary to confirm that the operating mechanism is flexible and free of sticking, and that the main electrical equipment and auxiliary contacts make reliable and accurate connections. At the same time, check whether the busbar connections are good, whether the instrument and transformer ratio and wiring polarity are correct, and whether the electrical device settings and fuse specifications meet the requirements.
2. Installation and Environmental Requirements
The installation location of a Container Type Substation should be chosen in a high area, avoiding low-lying places to prevent rainwater from entering the box and affecting equipment operation. No miscellaneous items should be stacked around it, and sufficient space must be ensured for ventilation and operational inspection of the electrical equipment. There must be at least two reliable grounding points between the Container Type Substation enclosure and the grounding network. The grounding network is usually formed by driving grounding rods at the four corners of the foundation and connecting them as a whole. The box base and all exposed metal parts should be treated for rust prevention and coated with a durable protective layer.
3. Maintenance and Inspection During Operation of Container Type Substations
Appearance and Cleaning: Regularly check whether the Container Type Substation has rust, deformation, or paint peeling and address issues promptly. Clean dust and debris inside the equipment and from transformer cooling fins to maintain good heat dissipation.
Electrical Connection Inspection: Check all electrical connection points of the Container Type Substation, especially connections of high-voltage cables and grounding lines, ensuring they are tight and secure to prevent heating or arcing faults caused by poor contact.
Ventilation and Temperature Control: Check if the ventilation holes of the Container Type Substations are blocked, and confirm that fans, air conditioners, and other cooling devices are working normally to prevent equipment overheating. Attention should be paid to not blocking the transformer room door to ensure cooling mainly by natural airflow.
Special Component Maintenance:
Terminal Blocks: Due to thermal expansion and contraction, terminals may become loose and should be re-tightened once a year, making sure the circuit is de-energized before operation.
Load Switches: For high-voltage load switches in operation, after a certain number of operations, the contact condition and the wear of the arc-extinguishing device should be checked.
Transformer: If an oil-immersed transformer is used in the Container Type Substation, it is recommended to sample and analyze the transformer oil once a year.
Surge Arresters: Preventive testing should be conducted once every year before the rainy season.
4. Safety and Other Precautions
Moisture and Leak Prevention: Regularly check the sealing strips and drainage holes of the Container Type Substation to ensure the enclosure is well-sealed with no leaks or accumulated water.
Operation Regulations: After manual operation of high-voltage load switches on-site, the operating handle should be returned to the bracket inside the outer door to prevent loss. For standby circuits of high-voltage ring main unit without cable connection, they must be closed or covered with a corresponding insulating cap before energizing. Using dust caps as substitutes for insulating caps is strictly prohibited.
Signs and Protection: The outer doors of Container Type Substations should have obvious live voltage warning signs and durable nameplates. Protective fences and warning signs should be set up around the equipment to ensure safety
V. Q&A on Knowledge Related to Container Type Substations
1. What role does a Container Type Substation play in a smart grid?
It is an important component of the modern smart distribution network. By integrating comprehensive automation, remote monitoring, and communication modules, it can achieve data acquisition, remote control, fault diagnosis, and unattended operation, thereby improving power supply reliability and management efficiency.
2. Are there any special requirements when installing a Container Type Substation?
Generally, it only requires a leveled and hardened foundation, hoisting the container into place, and connecting the incoming and outgoing cables. Some models support semi-buried installation to further save space. It is necessary to ensure good ventilation and meet safety distance requirements.
3. What equipment is mainly contained inside a Container Type Substation?
Mainly includes: multi-circuit high-voltage switchgear system, distribution transformer, low-voltage distribution devices, and often integrated electrical units such as substation comprehensive automation system, communication, metering, capacitor compensation, and DC power supply.
