Description

TMC 400 KVA TMCA resin transformer

1. Product Description

The 400 kva TMC brand transformer is a robust device designed to offer an efficient and safe distribution of electricity. With its resin construction, this transformer is particularly suitable for industrial and commercial environments where high reliability is needed. The specified model is designed to operate with tensions of 15 kV in medium voltage (MT) and 400 V in low voltage (BT).

2. Components and Structure

  • Brand and model: TMC 400 KVA
  • Type of transformer: resin transformer
  • Year of construction: not specified, but if used, it assumes that it respects contemporary rules and practices.
  • Primary voltage: 15 kV (average voltage)
  • Secondary voltage: 400 V (low voltage)
  • Power: 400 kva
  • Type of isolation: Resin, which offers excellent protection against humidity and external contaminations.

3. Dimensions and Weight

  • Dimensions: the specific dimensions are not supplied, but the 400 kva resin transformers usually have dimensions that allow easy integration into industrial spaces. The typical dimensions could be around 1.5 x 1.5 x 2 meters.
  • Weight: about 800 - 1,200 kg, depending on the configuration and accessories.

4. Mechanical Characteristics

  • Efficiency: high operational efficiency with reduced losses.
  • Reliability: designed to work in variable environments with high robustness and durability.
  • Protection: resin insulation that protects the transformer from adverse environmental conditions.

5. Usage Procedure

  1. Installation:

    • Positioning: place the transformer on a stable base and in a dry and ventilated environment.
    • Connect: make the connections between the transformer and the electrical network according to the technical specifications provided by the manufacturer. Connect medium voltage (15 kV) and low voltage (400 V) cables to their respective terminals.
  2. Switching on and Monitoring:

    • Ignition: follow the ignition procedures provided by the manufacturer, which include control of connections and gradual ignition.
    • Monitoring: verify that the transformer works correctly by monitoring parameters such as tension, current and temperature. Make sure there are no signs of malfunction.
  3. Maintenance:

    • Regular inspections: perform periodic inspections to check the integrity of the transformer and make sure there are no losses or signs of wear.
    • Cleaning: clean the external part of the transformer to remove dust and debris.

6. Matching accessories

  • Monitoring devices: temperature sensors and tools to measure electric parameters.
  • Cooling systems: fans or cooling systems for environments with high loads or high temperatures.

7. Mathematical Formulas for Optimal Use Parameters

  • Apparent Power:

    S=P2+Q2S = \sqrt{P^2 + Q^2}

    Where PP is the active power and QQ is the reactive power.

  • Transformer Efficiency:

    Efficiency=Output PowerInput Power×100%\text{Efficiency} = \frac{\text{Output Power}}{\text{Input Power}} \times 100 \%
  • Losses in the Transformer:

    Total Losses=Core Losses+Circuit Losses\text{Total Losses} = \text{Core Losses} + \text{Circuit Losses}

8. Materials and Applications

  • Workproof materials: suitable for resistive and inductive loads, guaranteeing reliable distribution of electricity.
  • Applications: used in industrial, commercial and residential environments where a stable and sure supply of electricity is needed.

9. Maintenance and Verification of Good Used Goods

  • Maintenance:

    • Periodic checks: carry out regular checks to verify the correct operation and prevent failures.
    • Cleaning: Remove dust and contaminants that could compromise operation.
  • Verification of Good Used:

    • External and internal conditions: inspect the transformer for signs of damage or wear. Check that all parties work correctly and that there are no losses.
    • Operation: Test the transformer to make sure you operate according to the specifications and without anomalies.
    • Documentation: verify that the transformer has the necessary documentation, including conformity certifications and maintenance tests.

10. Sectors of Use

  • Industrial: to provide energy to plants and machinery.
  • Commercial: for the feeding of buildings and commercial structures.
  • Residential: in residential areas with high energy demand.

11. Advantages of Buying Used

  • Lower cost: compared to a new transformer, the purchase of a used transformer can offer significant savings.
  • Reliability: a transformer used in good condition can provide comparable performance to a new unit.
  • Immediate Availability: Often available immediately, reducing waiting times for installation.
