Análise de dimensionamento de implantação de cabine metálica de média tensão classe 15 kV em condomínio vertical

Abstract

The present work presents a dimensioning analysis in a case study of the implantation of an armored metallic cabin of medium voltage class 15 kV in a vertical condominium, performing the function of a voltage step-down substation. Initially, considerations are made about the need for power substations in undertakings of this size, as well as aspects related to their main functions. Then, a brief study on substations is carried out, dealing with their classifications and their main equipment. In addition, the main characteristics that must be considered for parameterization of the components are presented. Throughout the work, an attempt is made to emphasize the norms of the Associação Brasileira de Normas Técnicas and Companhia Paranaense de Energia, which cover medium voltage electrical installations and delivery of primary energy through substations. In order to study the need to implement a metal cabin as a form of substation in vertical condominiums, to analyze its main elements and its minimum requirements to correctly dimension this type of installation, the main essential methods to carry out this case study with excellence. Finally, the work presents in detail the design case study, following the procedures contained in current norms through the addressed methodology.
