The utility model discloses there is round as a ball pickling glass sand inside packing of fuse, can effectively subtracts short arc time, reduce the potential safety hazard.
Description
Technical field
This utility model open a kind of fuse structure, the particularly fuse of a kind of big electric current of resistance to ac high voltage with arc suppression filling.
Background technology
Fuse (i.e. fuse) refers to when electric current exceedes setting, makes melt fuse with the heat that itself produces, a kind of electrical equipment of disconnecting circuit. 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
For the shortcoming that fuse of the prior art mentioned above can produce arcing in the moment of fusing, this utility model provides the fuse of a kind of new big electric current of resistance to ac high voltage with arc suppression filling, it is filled with quartz sand inside fuse, can effectively solve this problem.
This utility model solves its technical problem and the technical scheme is that the fuse of a kind of big electric current of resistance to ac high voltage with arc suppression filling, 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, it is filled with glass sand in body.
This utility model solves the technical scheme of its technical problem employing and further comprises:
Described quartz sand adopts the glass sand of round as a ball pickling.
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.
Described fuse-link is helically linear or linear, and fuse-link is vertically arranged in body or is obliquely installed.
The beneficial effects of the utility model are: this utility model is filled with round as a ball pickling glass sand inside fuse, can effectively shorten the arc time, reduce potential safety hazard.
Below in conjunction with the drawings and specific embodiments, this utility model is described further.

Detailed description of the invention
The present embodiment is this utility model preferred implementation, and other its principle all is identical with the present embodiment or approximate with basic structure, all within this utility model protection domain.
Refer to accompanying drawing 1, this utility model mainly includes body 1, fuse-link 2 and lead-in wire 7, fuse-link 2 is arranged in body 1, lead-in wire 7 is arranged on body 1 two ends, and electrically connect with fuse-link 2, inorganic arc suppression filling it is filled with in body 1, in the present embodiment, inorganic arc suppression filling is quartz sand 3, quartz sand 3 adopts high-purity (silicon (Si) content > 99.5%) and shape to be relatively regular approximate circle shape (approximate circle shape described in the utility model, refer to owing to natural siliceous sand is impossible to as circular, the glass sand adopted in the present embodiment connects rotund quartz sand for first passing through the selected rear shape of round as a ball process, it is referred to as approximate circle shape, shape is closer to circle, effect is more good) quartz sand (silicon dioxide, SiO2), it is used as arc suppression filling then through after pickling purification processes, and do not adopt the inorganic filler of the silicates containing metal oxide component, transship or when short circuit with the alternating current solved at high-voltage large current, avoid when the metal fuse-link within fuse at high temperature fuses, the metal ingredient of filler increases or improves overall gas metal ion concentration within fuse, cause that fuse is after fuse-link disconnects, persistently produce arcing or secondary arcing, form electric current and turn on phenomenon again, circuit cannot be fully disconnected in time. in the present embodiment, being respectively arranged at two ends with interior electrode 5 at body 1, lead-in wire 7 is connected to outside interior electrode 5, and electrically connects with interior electrode 5, and interior electrode 5 is internal to be electrically connected with fuse-link 2, in the present embodiment, is coated with external electrode 6 outside interior electrode 5. being respectively equipped with solder 4 between fuse-link 2 two ends with corresponding interior electrode 5, interior electrode 5 is electrically connected with fuse-link 2 by solder 4. in the present embodiment, fuse-link 2 adopts spiral yarn shaped fuse-link, when being embodied as, can also intert a supporter 9 in the middle of fuse-link 2.
Embodiment two: refer to accompanying drawing 2, the basic system of the present embodiment is identical with embodiment one, is different in that, in the present embodiment, fuse-link 2 adopts form of straight lines, and its inclined shape in body 1 is arranged.
Embodiment three: refer to accompanying drawing 3, the basic system of the present embodiment is identical with embodiment one, is different in that, in the present embodiment, fuse-link 2 adopts form of straight lines, and it is vertically arranged in body 1, and namely fuse-link 2 is perpendicular to interior electrode 5.
This utility model is filled with round as a ball pickling glass sand inside fuse, can effectively shorten the arc time, reduces potential safety hazard.
