Description
Technical field
The present invention relates to low voltage component technical field, and in particular to a kind of efficient arc extinguishing fuse.
Background technology
Fuse refers to when electric current exceedes setting, melt is fused with heat caused by itself, the one of disconnecting circuit
Kind electrical equipment.Fuse is after exceeding setting for a period of time according to electric current, to make Melt molten with its own caused heat, so as to
Disconnect circuit.
When in use, when short circuit or excessive electric current, melt can also produce electric arc when fusing, improper use, or not
Can effective arc extinguishing, can be unfavorable for using for a long time to fuse in itself or surrounding devices cause damage.Existing fuse arc extinguishing side
Formula is more, and in the majority in a manner of magnetic blow-out metal or insulation grid etc., complicated, arc quenching effect is bad.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide one kind is simple in construction, reasonable in design, makes
With convenient efficient arc extinguishing fuse.
To achieve the above object, the technical solution adopted by the present invention is：A kind of efficient arc extinguishing fuse, including terminals
Son, arc-chutes, melt；The binding post is two both ends for being separately positioned on the arc-chutes；Melt is provided with arc-chutes；
Two binding posts are connected with the both ends of melt respectively；Described arc-chutes are by upper and lower two insulation cover plates and insulation porcelain set group
Into；Annular air-pocket is provided with the inside of insulation cover plate；Annular air-pocket internal memory contains inert gas；Annular air-pocket is fixed on absolutely through melt
On edge cover plate；Position in annular air-pocket close to melt is provided with temperature sensor；The nozzle position of annular air-pocket is provided with valve；Valve
Door is connected with temperature sensor；Described insulated porcelain sleeve inwall is provided with insulation grid；
Preferably, described insulated porcelain sleeve and insulation grid are integral type structure；
Preferably, described inert gas is sulfur hexafluoride gas.
After said structure, the present invention has the beneficial effect that：Fuse of the present invention is in short circuit or electric current
When excessive, temperature sensor detects high temperature, and the valve of upper and lower two annular air-pockets is opened, and inert gas sprays from nozzle, knot
The efficient arc extinguishing of insulation grid in insulated porcelain sleeve, the infringement for effectively avoiding electric arc from bringing are closed, and is closed with simple in construction, setting
The advantages that reason, low manufacture cost.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also
To obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Description of reference numerals：
1st, melt；2nd, arc-chutes；3rd, binding post；4th, insulation cover plate；5th, insulated porcelain sleeve；6th, insulate grid；7th, annular air-pocket；8、
Temperature sensor；9th, valve.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is further illustrated.
Referring to shown in Fig. 1, the technical scheme that present embodiment uses is：It includes binding post 3, arc-chutes 2, melted
Body 1；The binding post 3 is two both ends for being separately positioned on the arc-chutes 2；Melt 1 is provided with arc-chutes 2；Two connect
Both ends of the line terminals 3 respectively with melt 1 are connected；Described arc-chutes 2 are made up of upper and lower two insulation cover plates 4 and insulated porcelain sleeve 5；
The inner side of insulation cover plate 4 is provided with annular air-pocket 7；The internal memory of annular air-pocket 7 contains inert gas；Annular air-pocket 7 is fixed on through melt 1
On insulation cover plate 4；Position in annular air-pocket 7 close to melt 1 is provided with temperature sensor 8；The nozzle position of annular air-pocket 7 is provided with
Valve 9；Valve 9 is connected with temperature sensor 8；The described inwall of insulated porcelain sleeve 5 is provided with insulation grid 6；
Preferably, described insulated porcelain sleeve 5 and insulation grid 6 are integral type structure；
Preferably, described inert gas is sulfur hexafluoride gas.
The insulation grid of present embodiment is integral type structure with insulated porcelain sleeve, need not specially be set in fuse exhausted
Edge grid, structure are simpler；Inert gas is sprayed in the both ends of melt simultaneously, and arc quenching effect is more preferable；Inert gas is using lithium
Sulphur, insulating properties are good, and arc extinguishing ability is higher 100 times than air.
It is described above, it is merely illustrative of the technical solution of the present invention and unrestricted, those of ordinary skill in the art are to this hair
The other modifications or equivalent substitution that bright technical scheme is made, without departing from the spirit and scope of technical solution of the present invention,
It all should cover among scope of the presently claimed invention.
