Description

Technical Field

[0001] The invention relates to the technical field of ceramic material preparation, and in particular to a high-voltage fuse ceramic tube material and a preparation method thereof. Background Art

[0002] The function of a fuse is the same as that of a fuse. When the circuit current is abnormal and exceeds its rated current, it will melt and protect the circuit. The fuse will melt the fuse itself and disconnect the circuit from the heat generated by itself. Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As a short circuit and overcurrent protector, it is one of the most commonly used protection devices. As a type of fuse, the fuse of a tubular fuse is installed in the fuse body. At present, the fuse body is mostly made of glass or ceramic. Since the mechanical strength of ceramic is far superior to that of glass, ceramic fuses have gradually become the mainstream. However, ceramics are brittle and are easily damaged when subjected to external forces, which affects the normal use of fuses. Summary of the invention
