Dimensionamento de uma rede de distribuição de energia eléctrica para o bairro de Mungassa, no Distrito da Beira, Província de Sofala

Abstract

This present work presents a suggestion for the implementation of a network of electricity distribution in Mungassaa, district of Beira, in Sofala to meet the needs of the residents of the neighborhood as well as for the urban development of the country. This was developed on the basis of knowledge acquired during the Electrical Engineering course at UEM together with the learning gathered during the professional internship at EDM, in the Beira Customer Service Area (ASC-Beira). During the internship I was assigned to two (2) departments: Department of Network Maintenance (DMR) and Statistics and Planning Department (DEP). In the first department, I went through three (3) sectors: Public Lighting (IP), Low Voltage Networks (RBT) and Medium Voltage Networks (RMT). Nonetheless with the help of technicians and engineers I learned several things, such as: Electrical maintenance of a transformer (replacement of screws and oil change); Execution of write-offs, both BT and MT; Execution of boxes; Placement of pass-through insulators (horizontal STV insulators) and end line (polymetric insulators); Uprighting of posts using slings; Installation of lamps; Placement of drop-outs, disconnectors, fuses and more protection. Based on all this, in our project, we designed the supports that will support the network and the lifting of the load requested by the neighborhood for the subsequent dimensioning of the transformer to be installed, of the conductors that will be mounted on the network and protections for the safety of people, goods and network devices and equipment. The illustration of the positions and installations of almost all the elements of the network is presented on a neighborhood electrification map, designed through the use of AutoCAD tool.
