Abstract

"PROCESSO DE SEGURANçA DE UM SISTEMA DE PROTEçãO DIFERENCIAL DE JOGO DE BARRAS EM UMA LINHA COM ISOLAMENTO GASOSO, E SISTEMA DE PROTEçãO DE APOIO QUE UTILIZA ESSE PROCESSO". A presente invenção refere-se a um processo de segurança destinado a acionar um sistema de proteção auxiliar, em caso de não funcionamento do sistema de proteção diferencial (2) após o aparecimento de um defeito elétrico (7) na linha. Ele é baseado na medida de pelo menos duas grandezas físicas (G1, G2, Gn) independentes por sistemas de medida (10), independentes do sistema de proteção diferencial (2), as medidas de cada grandeza sendo analisadas para produzir um sinal (11') que constitui um índice de presunção da presença ou da ausência de um defeito na linha. No caso de pelo menos dois índices de presunção da presença de um defeito se recortarem, um sinal (12') de inicialização de acionamento permitirá que uma unidade de acionamento (14) da proteção auxiliar espere um eventual sinal (13) de validação que será gerado caso o defeito não tenha sido eliminado pelo sistema de proteção diferencial após uma temporização determinada. Esse sinal de validação acarreta o fechamento de pelo menos um dispositivo (16) de seccionamento rápido de aterramento disposto na linha."SECURITY PROCESS FOR A DIFFERENTIAL BAR GAME PROTECTION SYSTEM IN A LINE WITH GASOUS INSULATION, AND SUPPORT PROTECTION SYSTEM USING THIS PROCESS". The present invention relates to a safety method for triggering an auxiliary protection system in case of non-functioning of the differential protection system (2) after an electrical fault (7) has appeared in the line. It is based on the measurement of at least two physical quantities (G1, G2, Gn) independent of measurement systems (10), independent of the differential protection system (2), the measurements of each quantity being analyzed to produce a signal (11). ') which is an index of presumption of the presence or absence of a line defect. In the event that at least two presumption indices of the presence of a fault cut out, a drive start signal (12 ') will allow an auxiliary drive drive unit (14) to wait for a possible validation signal (13) which will be generated if the fault has not been eliminated by the differential protection system after a certain time delay. This validation signal results in the closure of at least one grounding quick disconnect device (16) disposed in the line.
