Abstract
The utility model relates to an outdoor horizontally controlled automatic drop-out fuse, comprising a high-tension porcelain insulator, a fusing tube, and a driving mechanism. The driving mechanism is formed by a motor, and a gear-rack transmission device. A push-pull rod is solidly connected on an end of a rack in the moving direction. A tube carrier is solidly connected on the other end of the push-pull rod. An axis of the tube carrier, the push-pull rod, and the rack is in a rectilinear direction which is vertical to an axis of the fusing tube. The tube carrier, the push-pull rod, and the rack are connected with each other and are fixed on a mounting plate through a supporting plate. A center of the fusing tube is provided with a snap ring which is provided with arm shoulders on two sides of the snap ring. A front end of the tube carrier is a forked plate with a U-shaped gap. Tube clamping grooves are disposed on two sides of the U-shaped gap of the forked plate. The tube clamping grooves are movably connected with the arm shoulders in a matching manner. The outdoor horizontally controlled automatic drop-out fuse horizontally pushes or pulls the fusing tube to switch off or switch in. Installation space in a vertical direction is the same with that of a conventional manual drop-out fuse, and the conventional manual drop-out fuse can be directly changed into the outdoor horizontally controlled automatic drop-out fuse. The outdoor horizontally controlled automatic drop-out fuse is advantaged by simple structure, convenient installation, etc. The outdoor horizontally controlled automatic drop-out fuse is suitable to be used in transformer primary high-voltage cut-off switch which has relative small installation space in the vertical direction.
