Abstract

<B>"DISPOSITIVO E MéTODO RELATIVO à PROTEçãO DE UM OBJETO CONTRA CORRENTES EXCESSIVAS, COMPREENDENDO REDUçãO DE CORRENTE EXCESSIVA E LIMITAçãO DE CORRENTE"<D>. A presente invenção se refere a um dispositivo e método em uma instalação de energia elétrica, para proteção de um objeto (1) contra correntes excessivas de uma rede (3) ou outro equipamento incluído na instalação de alta tensão, o dispositivo compreendendo um dispositivo de comutação (4) em uma linha (2) entre o objeto e a rede/equipamento. A linha (2) entre o objeto e a rede/equipamento é conectada a uma disposição de redução de correntes excessivas (5) na direção do objeto (1), dita disposição (5) sendo ativada para redução de corrente excessiva com a ajuda de uma disposição (11, 13) de detecção de condições de corrente excessiva, dentro de um período de tempo substancialmente menor que o tempo de interrupção do dispositivo de comutação (4).<B> "DEVICE AND METHOD FOR PROTECTING AN OBJECT AGAINST EXCESSIVE CURRENTS, UNDERSTANDING EXCESSIVE CURRENT REDUCTION AND CURRENT LIMITATION" <D>. The present invention relates to a device and method in an electrical power installation, for protecting an object (1) against excessive currents from a network (3) or other equipment included in the high voltage installation, the device comprising a switching (4) on a line (2) between the object and the network / equipment. The line (2) between the object and the network / equipment is connected to an excess current reduction arrangement (5) in the direction of the object (1), said arrangement (5) being activated to reduce excessive current with the help of an arrangement (11, 13) for detecting excessive current conditions, within a period of time substantially shorter than the interruption time of the switching device (4).
