Abstract

"SISTEMA DE COMANDO DE MECANISMOS DE CONTROLE DE BARRAS DE REATOR NUCLEAR". A presente invenção refere-se a um sistema de comando, para cada bobina (2) de um mecanismo de controle de barras munido de três bobinas de comando alimentadas a partir de uma fonte de corrente trifásica um módulo de potência amovível independente. O módulo de potência (14) é conectado em série com a bobina (2) correspondente e comporta um circuito corretor (10) com três tiristores, controlados em ângulo de fase por um circuito de regulagem correspondente em função de valores de corrente convencional associados à bobina. Um circuito de controle conectado a uma interface de visualização permite visualizar a corrente que percorre a bobina associada ao módulo de potência. Em caso de defeito, o módulo e a bobina referidos são facilmente detectados e. substituídos sem necessitar da parada do conjunto do reator.
