摘要

Unipolar fuse disconnector perfected for overhead lines, characterized in that they include fixed contacts, upper opening and lower turning, fixedly mounted to the ends of. One or two insulators, the upper opening contact incorporating a flexible contact on which the foot of the pin of the fuse holder rests in connection and is clamped against said flexible contact by an interlock spring so that in a case the forced removal of this spring by means of a swing handle results in the release of the contact foot and the consequent opening of the disconnector, while the lower turning contact incorporates another flexible contact with which a retention lever of a cable corner makes connection. Of the fusible link, so that in the case of fusion of the link the lever removes the rest of the fusible link from inside the fuse holder thus avoiding the jump of the arc, at the same time as it pulls the fuse holder moving it and disconnecting it from the upper contact in the thus achieving the automatic opening of the disconnector.
