Abstract

The invention discloses a processing technology for a ceramic fuse tube of a DC fuse installation element. A DC fuse is composed of parts of a fuse element, a fuse tube and additional filling material. A fuse tube ceramic member is made of quinary system ceramic material. The components of the quinary system ceramic material include Al2O3, CaCO3, Cr2O3, SiO2 and MgO. Existing ceramic material is improved, and original ternary system material is improved to the quinary system material so that strength and harness of ceramics can be greatly increased and brittleness can be reduced.

Description

technical field [0001] The invention belongs to the processing technology of ceramic melting pipes, in particular to a processing technology of ceramic melting pipes for installing melts in DC fuses. Background technique [0002] The utility model relates to a ceramic melting tube for installing melt in a novel DC fuse, which relates to a DC fuse device. DC fuse is composed of melt, fuse tube and external filler. When in use, the fuse is connected in series in the protected circuit. When the current of the protected circuit exceeds the specified value and after a certain period of time, the fuse itself The generated heat blows the fuse and disconnects the circuit, thus playing a protective role. The electrical appliances that use metal conductors as the melt to break the circuit are connected in series in the circuit. When the overload or short-circuit current passes through the melt, the melt itself will generate heat and fuse, thus playing a role in the power system, vari...
