Abstract
The utility model discloses a high-voltage drop type fuse with an arch-quenching quick-break structure. The high-voltage drop type fuse comprises an insulating ceramic bush, a drop type insulating pipe, a rotation structure for connecting bottoms of the insulating ceramic bush and the drop type insulating pipe and an upper conductive sheet which is arranged on the upper part of the insulating ceramic bush and used for electrically connecting the drop type insulating pipe, wherein a vacuum arch-quenching chamber is formed in the drop type insulating pipe; a fuse wire is arranged in the arch-quenching chamber; two ends of the fuse wire are respectively connected to two ends in the vacuum arch-quenching chamber through fine springs; and an externally connected lead is arranged on the fine springs. The high-voltage drop type fuse is simple in structure; the vacuum arch-quenching chamber is formed in the drop type insulating pipe, and the fuse wire connected through the fine springs is arranged in the vacuum arch-quenching chamber, so that during fuse, the fuse wire is quickly broken towards two ends under the action of the springs at the two ends, and a quick-break effect of the fuse is achieved; and the high-voltage drop type fuse has a good arch-quenching effect and is safely and reliably used.
Description
Technical field
The utility model belongs to the fuse switch field, is specifically related to a kind of high voltage drop-out type fuse cutout with arc extinguishing quick-break structure.
Background technology
The conventional high-tension fuse switch is by insulator, the drop type arc-extinguishing tube, rotatable parts, upper and lower conducting strip and fuse form, it can complete electric disjunction effect to a certain extent, and on its structure, arc quenching effect is undesirable, fuse blast easily occurs or cause the appearance of short circuit phenomenon, use full safety poor, Chinese patent CN200620147924.5 discloses a kind of high-pressure drop-out fuse of high breaking, it is structurally main, and what adopt is that fusible link is packed in a sleeve pipe, and fill quartz sand to realize the arc extinguishing effect in sleeve pipe, it can reach the arc extinguishing effect to a certain extent, yet it is Shortcomings also, fill quartz sand in sleeve pipe, because there is weight in quartz sand, and quartz sand extruding downwards under Action of Gravity Field forms an active force by fusible link and goes between fixing, after making fusible link fusing, timely open circuit surely differs, and due to the weight of quartz sand, the drop type arc-extinguishing tube also be there will be when fusing is fallen and fall time delay or situation about not falling occurs, also there is certain potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, high voltage drop-out type fuse cutout with arc extinguishing quick-break structure of using safety.
The technical scheme that realizes the utility model purpose is a kind of high voltage drop-out type fuse cutout with arc extinguishing quick-break structure, comprise insulated porcelain sleeve, the drop type insulated tube, for connecting the rotational structure of insulated porcelain sleeve bottom bottom the drop type insulated tube and being arranged on insulated porcelain sleeve top for being electrically connected to the upper conducting strip of described drop type insulated tube, be provided with vacuum interrupter in described drop type insulated tube, at the indoor fusible link that is provided with of described vacuum extinction, the two ends of described fusible link are connected on the two ends of described vacuum interrupter by hairspring, described hairspring is provided with external lead wire.
Be provided with explosion-proof chamber between described drop type insulated tube and described vacuum interrupter.
The utlity model has positive effect: of the present utility model simple in structure, be provided with vacuum interrupter in the drop type insulated tube, at the indoor fusible link connected by hairspring that is provided with of vacuum extinction, when fusing is arranged, fusible link disconnects to two ends rapidly under the effect of two ends spring, complete fuse quick-break effect, and its arc quenching effect is good, safe and reliable.
The accompanying drawing explanation
For content of the present utility model is more likely to be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
Embodiment
(embodiment 1)
Fig. 1 has shown a kind of embodiment of the present utility model, and wherein Fig. 1 is structural representation of the present utility model.
See Fig. 1, a kind of high voltage drop-out type fuse cutout with arc extinguishing quick-break structure, comprise insulated porcelain sleeve 1, drop type insulated tube 2, for the rotational structure 3 that connects insulated porcelain sleeve 1 bottom and drop type insulated tube 2 bottoms be arranged on insulated porcelain sleeve 1 top for being electrically connected to the upper conducting strip 4 of described drop type insulated tube 2, be provided with vacuum interrupter 5 in described drop type insulated tube 2, be provided with fusible link 6 in described vacuum interrupter 5, the two ends of described fusible link 6 are connected on the two ends in described vacuum interrupter 5 by hairspring 7, described hairspring 7 is provided with external lead wire 8.
Be provided with explosion-proof chamber 9 between described drop type insulated tube 2 and described vacuum interrupter 5.
Obviously, above-described embodiment of the present utility model is only for the utility model example clearly is described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
