Claims

[Scope of utility model registration request]

An upper auxiliary electrode connects both ends of an insulating cylinder made of an inorganic material such as crystallized glass with a relatively small diameter to an upper electrode with an inserting blade and a lower electrode with an inserting blade, which are located and fixed on the upper and lower outer peripheries of the insulating cylinder. Fix and seal 1. In addition, there is a winding core made of an inorganic material such as alumina in the center of the insulating cylinder, and a synthetic resin storage cylinder that houses an indicator that indicates the blown state of the fuse at one end of the winding core on the lower electrode side. Directly connected, the storage tube is supported by the lower auxiliary electrode and the other end of the winding core is supported by the upper auxiliary electrode, and a fuse element is spirally wound around the outer circumferential surface of the winding core and the storage tube, and an insulating tube is also connected. The inner space is densely filled with arc-extinguishing material, and the outer circumferential surface of the synthetic resin storage cylinder is covered with an inorganic or heat-resistant material to protect it from the high heat of the arc when a large current is interrupted. A current-limiting fuse for high-voltage cut-out.
