The 5000kVA substation is crucial in providing stable power for industrial zones and large factories. Understanding technical specifications is vital to maximize efficiency.

Capacity and Technology

This substation has a rated capacity of 5000 kVA, using core steel lamination with copper or enamelled aluminum wire. Silicon steel cores minimize eddy currents due to superior magnetism. The standard operating frequency is 50 Hz.

Rated Voltage

Common high voltage ratings are 22kV or 35kV, and low voltage ratings are 0.4 kV or 6.6 kV. The typical connection group is Dyn11, ensuring reliability and power efficiency.

Energy Losses

• No-load loss (Po) ranges from 4980W to 11,000W depending on the transformer type.
• Short circuit loss (Pk) ranges from 39,500W to 53,000W.
• No-load current (Io) varies from 1.0% to 2.0%.
• Short circuit voltage (Uk) ranges from 4% to 7%.

Dimensions and Weight

For dry transformers, the standard size is about 2400mm (length) x 1800mm (width) x 2390mm (height). Copper winding weighs around 11,150 kg, while aluminum winding is approximately 10,000 kg.

Technical Standards, Testing, and Safety

International and Vietnamese standards applied include IEC 60076, IEC 60851, TCVN 6306. The standard frequency voltage test is 50/20 kV and impulse test voltage is 125/60 kV. Overload capacity is tested per IEC 60905 standards, ensuring safe and efficient operation.

Characteristics and Operational Care

Thin silicon steel cores reduce power loss, while coil design ensures electrical strength and high thermal resistance. Open-type transformers reduce noise and enhance durability. For storage, substations should be kept dry and protected from impact.

Recognizing these technical details aids management and engineers in making informed design and operational decisions for electrical systems.

In the energy and construction fields, executing the Construction Process and Maintenance Services is essential for ensuring system performance and safety. From initial electrical installations, vital steps are strictly followed to ensure maximum sustainability and safety.

• Install protective pipes and electrical cables:

• Utilizing pipe types like trunking, ladder, or exposed pipes to safeguard cables and systematize electrical routing forms the initial stage of electrical installation. This facilitates efficient cable management and enhances safety levels.

• Pulling cables according to design diagrams:

• Accurately pulling cables per design to minimize unnecessary risks such as electrical short circuits. Connections are best established in plug boxes or lamp groove boxes for easier repairs.

• Installing electrical cabinets and control devices:

• According to design diagrams, electrical cabinets and control panels must be installed to not only meet technical criteria but also harmonize with the overall system.

• Connecting, testing, and system acceptance:

• Before handover, systems undergo stages of connecting, testing, and acceptance to detect and correct potential issues. Operational trials ensure systems meet technical standards and electrical safety regulations.

• Installing water pipe systems:

• Completing water supply and drainage systems in accordance with design drawings ensures proper slope for drainage and seal integrity to prevent leaks.

• Underground electrical procedures:

• For underground electricity, ensuring conduit stability by securing them with cement or concrete is vital. Note that conduit ends should be smoothed and joint spacing should adhere to technical standards to prevent damage upon construction completion.

• Adhering to safety rules during construction:

• Safety measures like careful concrete drilling, using expandable bolts when installing cable trays, and ensuring alignment of threaded rods are crucial to prevent structural load damage.

Beyond construction, the maintenance process is pivotal to ensuring the water and electrical systems operate efficiently:

• Periodic inspection: Evaluate the condition of electrical wires and devices, perform maintenance or replacement for damaged components.
• Regular cleaning and maintenance: Assists in stable system operation and prolongs equipment lifespan.
• Electrical safety inspection: Conducted per standards to ensure safety during usage.
