摘要: An explosion-proof over-current protection element includes a fuse body, a ceramic shell, an explosion-proof layer, an arc-extinguishing layer, and a protection layer. The fuse body includes two electrodes and a fuse wire between the electrodes. The fuse body is integrally formed. The fuse wire is arranged within a cavity of the ceramic shell. The electrodes protrude from inside of the cavity toward outside of the cavity to contact an outer wall of the ceramic shell. The explosion-proof layer is arranged within the cavity and contacts a bottom surface of the cavity. The arc-extinguishing layer is arranged within the cavity and covers the fuse wire. The explosion-proof layer and the arc-extinguishing layer are made of different materials. The protection layer is arranged within the cavity. The arc-extinguishing layer is located between the explosion-proof layer and the protection layer.

摘要: A fuse link used in alternate current medium- or high-voltage systems with a current frequency of 50 Hz includes a spring-type striker pin and is designed for the protection of electrical devices against consequences of short circuits and overloads. A porcelain housing with a star-core, external end caps closed by plugs, star-core end caps with a ring-shaped first tap designed to ensure electric contact between the star-core end cap and the external end cap of the fuse link is also included. A spring-type striker pin is positioned along the axis of the star-core. Each of the end caps of the star-core is provided with an additional second tap designed to centre the star-core relative to the axis of the fuse link. The spring-type striker pin is centred along the longitudinal axis of the fuse link.
