Fuse is after exceeding setting a period of time according to electric current, makes Melt molten with the heat that himself produces, so that circuit disconnects, uses a kind of current protector that this principle is made. Fuse is widely used in high and low voltage electric distribution system and control system and electrical equipment, as the protector of short circuit and overcurrent, is apply one of most common protection device. Problem due to the operation principle of fuse so that it produces phenomenon of arc discharge in the moment of fusing, it is easy to initiation fire, causes the accident, and therefore it in use, exists certain potential safety hazard.
Summary of the invention
Arcing and the shortcoming that the caused end cap punching of the impact of two end caps is taken off can be produced in the moment of fusing for fuse of the prior art mentioned above, this utility model provides a kind of new high voltage withstanding high-current fuse protector structure, it is filled with quartz sand inside fuse and fuse-link two ends are provided with inorganic arc quenching material, can effectively solve this problem.
This utility model solves its technical problem and the technical scheme is that a kind of high voltage withstanding high-current fuse protector structure, fuse structure includes body, fuse-link and lead-in wire, fuse-link is arranged in body, lead-in wire is arranged on body two ends, and electrically connect with fuse-link, being filled with glass sand in body, fuse-link two ends are provided with inorganic arc quenching material.
This utility model solves the technical scheme of its technical problem employing and further comprises:
Described quartz sand adopts round as a ball pickling glass sand.
Described body is respectively arranged at two ends with interior electrode, and lead-in wire is connected to outside interior electrode, and electrically connects with interior electrode, and interior electrode interior electrically connects with fuse-link.
It is coated with external electrode outside described interior electrode.
Being respectively equipped with solder between described fuse-link two ends with corresponding interior electrode, interior electrode is electrically connected with fuse-link by solder, and inorganic arc quenching material is arranged between fuse-link and solder.
