V-shaped drop-out fuse

An upper supporting plate and a lower supporting plate are connected to the two ends of a middle supporting plate in the length direction, the upper supporting plate and the lower supporting plate form acute angles with the middle supporting plate, the middle of the upper supporting plate in the width direction extends to form an upper opening through groove, and the upper opening through groove penetrates through the upper supporting plate in the width direction; a lower opening through groove extends out of the middle of the lower supporting plate in the width direction and penetrates through the lower supporting plate in the width direction. According to the V-shaped drop-out fuse provided by the utility model, the auxiliary fixing piece and the insulator fixing seat are matched to form a triangular structure, so that the structural strength of the V-shaped drop-out fuse is guaranteed; the auxiliary fixing piece and the insulator fixing seat are of a split structure, and after the first bolt piece and the
