Description

technical field [0001] The invention belongs to the technical field of fuse processing technology, and in particular relates to a processing technology of a highly reliable small-sized high-voltage tubular fuse. Background technique [0002] Small high-voltage tubular fuses are mainly used in circuit systems of aviation, radar, airborne computers, precision instruments, etc., to protect the safe operation of circuits. When the current of the protected circuit exceeds its rated current value and after a certain period of time, the heat generated by the fuse itself will fuse the fuse to disconnect the circuit, thus playing a protective role. [0003] When the fuse melt is disconnected, an arc voltage will be generated. If the arc voltage cannot be quickly absorbed, the circuit may form a secondary conduction, which will endanger the safety of equipment and personnel. [0004] At present, the highest voltage of domestic small tubular fuses is 125V, and there is no military tub...
