Power Transformer Assembly Production Line

The process flow of transformer production line mainly includes the following key steps:

1. Coil winding:

Installation of winding frame: First, it is necessary to install the winding frame, which is the foundation of coil winding.

Winding coil: Wrap wires on the skeleton to form the coil part of the transformer.

Wire welding: Weld the wound coil to ensure the firmness of the connection.

Insulation: Insulate the coil to prevent short circuits and electrical breakdown.

Coil shaping: Adjust the shape of the coil to meet the design requirements.

Coil testing: Electrical performance testing of the coil to ensure compliance with technical standards.

2. Iron core assembly:

Silicon steel sheet cutting: Cut the silicon steel sheet into the required size.

Deburring: Process the edges of silicon steel sheets to remove burrs.

Stacking iron core: Stack the cut silicon steel sheets according to the design requirements.

Install pull plates and shields: Install pull plates and shields to secure the iron core and reduce eddy current losses.

Tie the iron core: Fix the iron core with straps to ensure its structural stability.

Iron core test: Conduct performance testing on the assembled iron core.

Install iron core clamp: Install the iron core into the clamp of the transformer.

3. Insulation processing:

Insulation cutting: Cut insulation materials according to design requirements.

Deburring: Process the edges of insulation components to ensure they are smooth and free of burrs.

Chamfer: Chamfer the edges of insulation components to reduce stress concentration.

Moisture proof treatment: Apply moisture proof treatment to insulation components to improve their moisture resistance performance.

4. Processing of oil tanks and storage tanks:

Steel plate cutting: Cut the steel plate according to the design drawings.

Welding of fuel tank and oil storage tank: Weld the cut steel plate into the fuel tank and oil storage tank.

Rust removal: Remove rust from welds and surfaces.

Sandblasting: Sandblasting the surface of the fuel tank to improve the adhesion of the paint film.

Primer: Apply primer on the surface of the fuel tank to protect the steel plate from corrosion.

Spray painting: Spray painting the fuel tank to improve appearance quality and anti-corrosion performance.

Mechanical strength test: Conduct a strength test on the fuel tank to ensure that it meets safety requirements.

5. General assembly:

Install iron core: Install the iron core into the main structure of the transformer.

Installing fuel tank pipelines: Installing fuel tanks and related piping systems.

Wrap the coil: Wrap the coil onto the iron core.

Stacking iron yokes: Stack the iron yokes onto the iron core.

Install tap changer: Install tap changer to adjust the output voltage of the transformer.

Welding lead: The lead that connects the welding coil to the outside.

Wrap lead insulation: Insulate the soldered leads.

Semi finished product test: Conduct performance testing on semi-finished transformers.

Body drying: Dry the transformer body to remove moisture.

Organize the transformer body: Organize the transformer body to ensure a clean appearance.

Oil tank assembly: Assemble the oil tank and transformer body together.

Attachment assembly: Install various accessories for transformers, such as thermometers, pressure relief valves, etc.

Oil injection: Inject insulating oil into the fuel tank.

Sealing test: Conduct a sealing performance test on the fuel tank.

Hot oil circulation: Through the hot oil circulation system, ensure uniform oil temperature and improve insulation performance.

Quiet: Let the transformer stand for a period of time to stabilize its performance.
