Transformer Final Assembly Line
The transformer final assembly line refers to a specialized production line that assembles core components of a transformer, such as the iron core, windings, oil tank, and insulating parts, into a complete and qualified transformer product in accordance with process standards. It is essential to ensure the product’s insulation performance, electrical stability, and structural reliability.
The process of the transformer final assembly line mainly consists of three core stages:
- Preliminary Preparation: Clean and inspect the main components of the transformer (coils, iron core, oil tank) to prevent impurities from affecting insulation performance.
- Core Assembly: First, stack the iron core, then assemble the high-voltage and low-voltage windings, weld the lead wires, followed by drying the transformer body. After that, install the transformer body into the oil tank and fit accessories such as bushings and pressure relief valves.
- Testing and Finalization: Remove gas from the insulation layer through vacuum oil filling, conduct a sealing test, and after standing, carry out electrical tests including transformation ratio test, insulation resistance measurement, and withstand voltage test. Only after passing all tests can the product be packaged and prepared for delivery.
