IMPLANTAÇÃO DO SELO HIDRÁULICO EM UNIDADES GERADORAS VERTICAIS: estudo de caso da Usina hidrelétrica de Itutinga-MG

Abstract

This article analyzes the application of a hydraulic seal in a generating unit at a plant maintained by Companhia Energética de Minas Gerais – CEMIG, located in the city of Itutinga – MG. Such approach is necessary due the fact that the oil vapor from the heating of the bearing impregnates in the generator causing machinery shutdown and consequently the reduction of the production. The aim of this study is to prove that the implantation of the hydraulic seal is extremely important and, mainly, effective. This task will be accomplished through data analysis and case study. With this work it will be possible to show the gains in energy generation and saving, as well as the optimization of the workforce. Factors such as reduced risk of loss of insulation among stator coils, greater reliability in the National Interconnected System, elimination of activities with risk to human health and safety, employee satisfaction and non-hazardous waste generation will be also analyzed.
