Step-by-Step Guide to Build Transformer

1. Design and Planning

Before building a transformer, engineers meticulously design transformers based on specific customer requirements and technical parameters. Factors such as rated load, input/output voltage levels, and insulation requirements are carefully considered. Advanced simulations and calculations are conducted to validate the design's feasibility and efficiency. Comprehensive technical documents and drawings are prepared to guide subsequent manufacturing stages.

2. Material Preparation

The building process commences with the meticulous preparation of materials essential for transformer construction. Key materials include silicon steel sheets, insulating materials, wires, insulating glue, and protective paints. Each batch of materials undergoes rigorous screening and testing to ensure compliance with national standards and performance requirements. High-quality materials are crucial for achieving optimal transformer performance and longevity.

3. Cutting and Assembly

Central to transformer assembly is the precise cutting and assembly of silicon steel sheets according to design specifications. Precision cutting tools and equipment are employed to ensure exact dimensions and shapes, crucial for efficient magnetic flux within the transformer core. Assembled silicon steel sheets are meticulously configured into iron cores, ensuring adherence to geometric and size requirements specified in the design.

4. Winding and Insulation Treatment

Winding, a critical component of transformer construction, involves carefully winding copper wires onto the assembled iron core. Each winding layer is meticulously insulated with epoxy-coated insulation paper to prevent electrical contact and ensure robust insulation integrity. This process demands precise execution to maintain winding quality, efficiency, and minimal energy loss.

5. Assembly and Welding

Following the completion of core and winding components, transformers undergo comprehensive assembly and welding processes. Skilled workers meticulously assemble all components according to design specifications, ensuring secure and reliable connections without any potential for leakage or short circuits. Concurrently, essential components such as cooling systems and oil tanks are installed to facilitate optimal transformer performance.

6. Insulation Testing and Debugging

Post-assembly, transformers undergo rigorous insulation testing and debugging procedures to guarantee operational safety and reliability. Various tests, including insulation resistance measurement, dielectric loss assessment, and short-circuit impedance testing, validate transformer performance parameters. Thorough debugging ensures that any potential operational issues are identified and resolved before deployment.
