The invention discloses a transparent fuse. The fuse comprises an upper base plate, an insulator upper hardware fitting, an insulator, a mounting plate, an insulator lower hardware fitting, a lower base plate, a lower tension disc, a fusion tube lower
copper cap, a fusion tube lower hardware fitting, a fusion tube, a fuse, a fusion tube upper hardware fitting, a pressure relief cap, a static contact plate, a spring and an upper tension disc, wherein the mounting plate is arranged in the middle of the insulator; a fusion tube outer sleeve is sleeved on the fusion tube, and the lower end of thefusion tube is sleeved and fixed in the fusion tube lower hardware fitting, and the upper end of the fusion tube is sleeved and fixed in the fusion tube upper hardware fitting with a hook. The transparent fuse is characterized in that a transparent umbrella is sleeved on the insulator; the transparent fusion tube outer sleeve is sleeved on the fusion tube; 0 to 4 slotted holes are arranged in themiddle section of the fusion tube;
tungsten-
copper is welded on the fusion tube upper
copper cap; and
tungsten-copper contacts are welded at the bottom of the pressure relief cap. The fuse can be used for quickly and visually detecting and determining whether the fuse is fused or not, so that the transparent fuse can be repaired in time to ensure
safe operation of the transmission circuit. The fuse has low production cost,
high standard degree, high product quality, high
mechanical strength and long service lie, and can meet the requirement on high, medium and
low voltage circuit fuses.
