Application of Vacuum Casting Production Processes in Transformer Manufacturing

Introduction:

Transformers are essential devices widely used in power systems for measuring current and voltage, converting them into usable signals for monitoring and control systems. The performance and reliability of transformers are crucial for the proper operation of power systems. To enhance the quality and performance of transformers, new production processes are continuously being introduced. This article focuses on the application of vacuum casting production processes in transformer manufacturing.

Introduction to Vacuum Casting Production Process:

The vacuum casting production process is another commonly employed manufacturing technique for transformers. It involves injecting epoxy resin into the gaps between the transformer windings under a vacuum environment, fully impregnating the windings, and solidifying to form the insulation layer. The vacuum casting production process offers the following advantages:

Uniformity: Vacuum casting ensures the uniform filling of epoxy resin into the gaps of the windings, eliminating bubbles and voids, thereby increasing the density and uniformity of the insulation material.

High insulation strength: Through vacuum casting, epoxy resin can make full contact with the windings, forming a high-strength insulation layer, thereby enhancing the insulation capability of transformers.

Heat resistance and electrical breakdown resistance: Transformers produced through vacuum casting possess high heat resistance and electrical breakdown resistance, enabling stable operation in high-temperature and high-voltage environments.

Conclusion:

APG and vacuum casting production processes are two commonly used techniques in transformer manufacturing. By utilizing injection molding and vacuum casting, these processes ensure a tight integration between insulation materials and transformer windings, resulting in improved accuracy, insulation performance, and reliability. With continuous technological advancements, these processes will continue to evolve, bringing further innovation and enhancements to transformer manufacturing.
