Abstract(s)
Devido à natureza da rede de distribuição existente em Portugal, os seccionadores são um elemento vital para a gestão da mesma. Estes continuam a ser a alternativa mais rápida para efetuar o corte visível nas linhas, permitindo às equipas no terreno trabalhar em segurança.
Em muitos casos, onde não existem outros elementos de corte são essenciais para a deteção de avarias nas linhas. Posto isto, é do total interesse da EDP Distribuição conhecer as taxas de avarias nestes órgãos/principais causas raiz e agilizar o processo de escolha do tipo de seccionador a instalar em locais específicos da rede MT, tripolares versus unipolares. Para responder a estes dois interesses a presente dissertação foi dividida em duas componentes core; a primeira reporta a um estudo referente às taxas de avarias anuais e às causas raiz da falha dos seccionadores instalados nas linhas aéreas de MT (Média Tensão) na AMN (Área de Manutenção Norte) durante os anos de 2013 e 2017 e a segunda reporta à criação de uma aplicação para computador para agilizar o processo de escolha do tipo de seccionador a instalar ou substituir, tendo em atenção a especificidade do local da rede. Esta aplicação vai selecionar o seccionador, tendo em atenção as diretivas internas definidas pela EDP Distribuição.
Due to the nature of the existing distribution network in Portugal, the air switches are na essential element for the grid management. These remain the fastest way to achieve overhead lines visible isolation, allowing the teams on the ground to work safely. In many cases, where there are no other equipment’s that can achieve overhead lines isolation, these remain essential for the detection of malfunctions. So, it is in the interest of EDP Distribuição to know the fault rates in these organs/the root causes of the faults, and also, to speed up the process of finding the most suitable type of air switch that we be installed at specific locations of the MT (medium voltage) grid, tripolar versus unipolar. To achieve these two purposes this dissertation was divided into two core components; The first is a study concerning the annual fault rates and the root causes of the fault, during the years 2013 and 2017 that have occurred in air switch s installed in the overhead lines of MT in the AMN (North Maintenance Area). The second is the creation of a computer application that will fasten the choosing process of the air switch type to be installed or replaced according with the location and function in the grid. Considering the internal legislation defined by EDP Distribuição, the application will select the most suitable air switch to be used.
