Title (EN) SWITCHING-TYPEDISTANCE RELAY APPARATUS
(FR) APPAREIL DE RELAIS A DISTANCE DU TYPE A COMMUTATION
Abstract: front page image
(EN)A distance relay apparatus of the type in which signals corresponding to input voltage and current are converted into signals of which suitable ones are selected in accordance with fault conditions and then introduced to a measuring element (5), the improvement wherein switching contacts are not actuated directly by the outputs of fault detecting elements (2), (3) but rather, a switching circuit (4) is actuated through a switching logic circuit (11). This provides a switching-type distance relay apparatus which is highly reliable and low in cost, and which is not readily influenced by contact resistance at switching contacts.
(FR)Un appareil de relais a distance du type dans lequel des signaux correspondant a la tension et au courant d"entree sont convertis en signaux parmi lesquels ceux qui sont appropries sont selectionnes en fonction des conditions de fuite puis sont introduits dans un element de mesure (5), l"amelioration consistant en ce que des contacts de commutation ne sont pas actionnes directement par les sorties des elements de detection de fuite (2, 3) mais un circuit de commutation (4) est actionne par l"intermediaire d"un circuit logique de commutation (11). Ceci permet d"obtenir un appareil de relais a distance du type a commutation extremement fiable et peu couteux, et qui n"est pas influence facilement par la resistance des contacts aux points de contact de commutation.
