Description
Technical field
The utility model is related to electric circuit protection equipment technical fields, and in particular to a kind of adaptable scalable fusing
Device.
Background technology
Fuse is series in circuit using metallic conductor as melt, when overloading or short circuit current passes through melt,
It fuses because its own generates heat, to a kind of electric appliance of disjunction circuit.Fuse structure is simple, easy to use, is widely used in electricity
As protection device in Force system, various electrical equipments and household electrical appliance.The current protection principal mode of electrical equipment included
Carry delay protection and short-circuit instantaneous protection.Overload generally refers to 10 times of rated current overcurrent below.It is short-circuit then refer to being more than
Overcurrent more than 10 times of rated current.Overload protection and short-circuit protection are certainly not only electric current multiple difference, actually difference very
Greatly.In terms of characteristic, overload needs inverse time protection characteristic, short-circuit then need instantaneous protection characteristic.Come in terms of parameter
It sees, overload requires fusing coefficient small, and heating time constant is big, short-circuit then require larger current limiting factor, smaller fever time
Constant, higher breaking capacity and lower overvoltage.From the point of view of operation principle, the physical process of overload action mainly heats
Change process, and short circuit is mainly then the extinguishing process of electric arc.
Fuse is mainly made of melt, shell and electrode section, and wherein melt is the key element for controlling operating chacteristics.
Material, the size and shape of melt determine operating chacteristics.The shape of melt is divided into Filamentous and two kinds of sheet type.For sheet type
For melt, in fusing process, since electric arc is excessive, shell is easily damaged so that causing fire, and existing sheet type is protected
Dangerous silk, fusing speed is slower, not can be well protected electric appliance.Filamentous melt fuse application is wider.But it many times, fuses
Device application form is relatively narrow, in the equipment for not adapting to plurality of specifications size.
Utility model content
In view of above-mentioned disadvantage, the purpose of this utility model is to provide a kind of fuse, the fuse can root
Factually border service condition, and stretch, to adapt to various sizes of installation equipment.The fuse comprising electrode, insulation crust
And melt, the fuse is in filiform, i.e., fuse, insulation crust are divided into outer barrel shell and interior cylinder shell, and interior cylinder shell can be along outer
Cylinder shell slides, and by the sliding of interior cylinder shell, the fuse can extend or shorten, to which the installation for adapting to different is set
It is standby.
Further, the fuse is arranged in the shape of a spiral, so as to extend or shorten with insulation crust.
Further, the both ends of the fuse are separately fixed in two end electrodes.
Further, the fuse is connected by welding manner with two end electrodes.
Further, the two end electrodes include left electrode, right electrode, and the left electrode is fixed at the outer cylindrical casing
On body, the right electrode is fixed on the interior cylinder shell.
Further, the interior cylinder shell is deviate from from the outer barrel shell in order to prevent, the interior cylinder shell and described
The end set limited block of outer barrel shell.
Further, Outer cylinder stop block is set on the outer barrel shell, inner cylinder limited block is set on the interior cylinder shell, when
When the interior cylinder shell is retractable to maximum length, the Outer cylinder stop block and the inner cylinder limited block can cooperate, to
The interior cylinder shell is limited from the outer barrel shell to deviate from.
Further, the interior cylinder shell and the outer barrel case inside are attached to ceramic-lined, and ceramics can have very
Good insulation and thermal insulation effect, improves the service life of fuse.
As described above, the utility model can reach following effect：
One, by the way that the interior cylinder shell and the outer barrel shell to be configured to be slidably matched, and the fuse is set
It is set to helical form, can be stretched, so that the fuse can be suitable for the equipment of different size.
Two, the interior cylinder shell and the outer barrel case inside are attached to ceramic-lined, and ceramics can have well absolutely
Edge insulation effect improves the service life of fuse.
Three, the end of the interior cylinder shell and the outer barrel shell is respectively provided with limited block, can be good at preventing in described
Cylinder shell is deviate from from the outer barrel shell.
Description of the drawings
Fig. 1 is the schematic diagram of the scalable fuse of the utility model.
Wherein reference numeral is briefly described as follows：
1 outer barrel shell；Cylinder shell in 2；3 fuses；4 left electrodes；5 right electrodes
6 Outer cylinder stop blocks；7 inner cylinder limited blocks；8 solder joints.
