Desenvolvimento de um sistema de gerenciamento de transformadores de potência instalados no sistema de transmissão da Companhia Estadual de Energia Elétrica

摘要

This dissertation describes the conception, the implantation of the results reached in the development of "SGTF - CEEE / ATTN" - System of Administration of Power Transformers, that was implanted in the Area of Transmission of CEEE. It has as reference the experience of the energy company as well as a bibliographical revision of the methodologies and techniques regarding the theme. It begins with an approach on the evolution of the industrial engineering maintenance in Brazil, drawing a parallel one what happened in the evolution of the maintenance of transformers in the Brazilian electric system, it goes by a revision in the concepts of power transformers, degradation of the insulating system, identification of emissions through analysis of the gases dissolved in the oil and aging of the insulating paper. The base concepts of the Administration of Power Transformers are demonstrated through the details of the structures and resources of the "Modules" or available "Tools" in the system: Modules of Register, Maintenance, Evaluation of the Useful Life and Monitoring. The results and benefits reached with the implantation of the system of administration of transformers are presented as well as the advantages in applying the same ideas to the other equipments or facilities of the energy company.
