Diseño Analítico del Cambio de Relación de Transformación de un Transformador de Distribución de 15 kVA - 13,8 kV/0.22-0.11 A 22 kV

Abstract

This degree work addresses the challenge of adapting a 15 kVA single-phase distribution transformer originally configured for 13.8 kV distribution networks for line-to-line voltages on its primary side and 120/240 V on the secondary side, to new voltage conditions. distribution at 22 kV for line-to-line voltages on its primary side and 120/240 V on the secondary side. Located in the High Voltage Laboratory of the Salesiana Polytechnic University – Guayaquil Campus, the project focuses on raising the voltage of the theoretically supplied transformer without reducing its nominal power. The methodology used is based on an analytical design that defines the dielectric characteristics through theoretical calculations and on the determination of 3D digital modeling using ANSYS Maxwell software. Specifications are proposed for changing the medium voltage winding, ensuring the adaptation of the transformer. 3D modeling with ANSYS Maxwell allows you to simulate voltages and currents, providing a comprehensive view of the proposed modifications. Discussion of the results highlights the agreement with the project objectives and the critical evaluation of the effectiveness of the winding change to satisfy the new voltage conditions. Recommendations are issued for possible future improvements and adjustments, and the importance of this work in the context of electrical redesign is reflected. This summary encapsulates the methodological approach, the results obtained and the practical implications of the project, offering a vision of the effort dedicated to the adaptation of an essential component in the technical area.
