Abstract

This paper aims to analyze, technically and economically, the benefits of the copper utilization on new windings of repaired distribution transformers, originally designed for aluminum. Three commercial single-phase distribution transformers commonly installed on urban and countryside areas of Brazil were submitted to routine tests and temperature rise test. All the tests were performed at LAT-EFEI- High Voltage Laboratory in accordance to Brazilian standards and the Brazilian Labeling Program (PBE) for oil-immersed distribution transformers. The technical evaluation compares the losses before and after the repair process and the temperature rise test results of the repaired transformers. The economic analysis is based on load losses and no-load losses capitalization along the equipment useful lifetime and compares the investment in a repaired level C transformer, made with copper, against level E transformer, made with aluminum, providing the net present value and the investment payback time.

原铝制配电变压器检修新绕组用铜的技术经济分析

本文旨在从技术和经济上分析在检修后的配电变压器新绕组上使用铜的效益。对巴西城市和农村常用的3台商用单相配电变压器进行了常规试验和温升试验。所有测试均在late - efei高压实验室按照巴西标准和巴西油浸式配电变压器标签计划(PBE)进行。技术评价比较了修复前后的损耗和修复后变压器的温升试验结果。经济分析是基于负载损耗和空载损耗资本化的设备使用寿命，并比较用铜制造的C级变压器和用铝制造的E级变压器的投资，提供净现值和投资回报时间。
