Electrical Transformation Cabin with Resin Transformer, 400 KVA

1. Product Description

The electrical transformer cabin, designed for medium voltage (15,000 V) to low voltage conversion, is a 10-foot mobile unit that houses a 400 KVA cast resin transformer. The cabin, of unspecified make and model, is almost new, produced in 2014 and complies with CEI 06-16 standards. This solution is ideal for temporary or mobile applications that require a reliable power supply.

2. Materials and Components

• Cabin:

  • Structure: Made of metal, designed to withstand adverse environmental conditions and to ensure operational safety. The structure is designed to be robust and resistant to atmospheric agents.
  • Dimensions: 10 foot container (approximately 3.05 x 2.44 x 2.59 meters), standard size for mobile units.

• Resin Transformer:

  • Insulation: Uses epoxy resin for insulation, a choice that provides greater environmental protection and longer life than traditional insulators.
  • Core: Constructed of silicon steel sheet, designed to reduce energy losses and improve efficiency.
  • Windings: Made of copper to ensure high conductivity and low resistance.

3. Dimensions and Weight

• Rated Power of the Transformer: 400 KVA
• Input Voltage (Medium Voltage): 15,000 V
• Output Voltage (Low Voltage): Typically 400 V or 230 V, depending on final specifications.
• Cabin Dimensions: 10 feet (3.05 x 2.44 x 2.59 meters)
• Weight of the Transformer and the Cabin: The total weight may vary, but is generally around 3,000-4,000 kg.

4. Mechanical Characteristics

• Efficiency: High, thanks to the resin insulation and the silicon steel core, which reduces energy losses.
• Thermal Stability: Excellent, with the resin transformer offering good heat dissipation and operational stability.
• Insulation: Excellent, with the use of resin protecting the transformer from contamination and moisture, improving durability and safety.

5. Usage Procedure

1. Installation: Place the cabin on a flat and stable base. Make sure the area is adequately ventilated and that there is access for maintenance.
2. Connection: Connect the high voltage cables to the medium voltage section and the low voltage cables to the low voltage section, following the safety regulations.
3. Power On: Turn on the cabinet and monitor operating parameters, including voltage, current and temperature.
4. Monitoring: Conduct regular checks to ensure correct operation and identify any problems before they become critical.

6. Matching accessories

• Monitoring Devices: Sensors for temperature, voltage and current.
• Alert Systems: Alarms for malfunctions or anomalous conditions.
• Cooling System: Fans or additional cooling units if necessary for particularly hot environments.

7. Mathematical formulas

• Apparent Power: S = \sqrt{(V_{\text{primary}} \times I_{\text{primary}}) \times (V_{\text{secondary}} \times I_{\text{secondary}}) Where VV $V$ is the voltage and II $I$ is the current.
• Efficiency: Efficiency=Output PowerInput Power×100%\text{Efficiency} = \frac{\text{Output Power}}{\text{Input Power}} \times 100 \% $$\text{Efficiency}$$ $$=$$ Input Power Input Power Output × $$100\%$$
• Core Losses: Measurable through eddy current and hysteresis loss analysis.

8. Materials He Can Work with

• Resistive Loads: Devices and equipment that require constant power.
• Inductive Loads: Motors and secondary transformers.
• Capacitive Loads: Compatible, but check specifications for highly capacitive loads.

9. Maintenance

• Insulation Inspection: Regularly check the condition of the resin and check for signs of deterioration.
• Temperature Control: Monitor the operating temperature and ensure it is within specified limits.
• Cleaning: Keep the cabin and its components clean and well ventilated. Check the seals and connections periodically.

10. Verification of Good Used

• General Condition: Make sure there are no signs of physical damage or wear. Check the condition of the resin and the absence of oil leaks or contamination.
• Operational Tests: Test the system to confirm that all functions are operational and that parameters are within specified limits.
• Documentation: Check maintenance documentation and certifications to confirm quality and compliance with CEI 06-16 standards.

11. Sectors of Use

• Industry: For temporary or mobile applications requiring reliable medium to low voltage transformation.
• Construction: Used on construction sites and construction areas where a temporary electrical connection is required.
• Events and Trade Shows: Ideal for powering temporary electrical systems at outdoor events and trade shows.

12. Advantages of Buying Used

• Lower Cost: Purchasing a used transformer cabin can result in significant savings compared to purchasing a new one.
• Guaranteed Quality: Being almost new, the cabin and transformer probably have a long useful life left.
• Immediate Availability: The used cabin is ready for immediate purchase and installation, reducing waiting times.

In summary, the 400 KVA resin transformer electrical transformer cabin is a versatile and reliable solution for temporary or mobile applications. With good maintenance and careful checking of the condition, this equipment can offer excellent performance for many years. If you have further questions or need more details, I am at your disposal!
