Description
Technical field
This utility model relates to a kind of Internal fuse, and specifically Copper Foil formula high-voltage capacitor Internal fuse, belongs to high-voltage capacitor technical field.
Background technology
At present, capacitor Internal fuse technology development at home and perfect, one of main protection components and parts having become as capacitor.Internal fuse element each with capacitor internal is connected, and after capacitor element punctures, Internal fuse fusing connected in series, the fuse of fusing plays the effect of open circuit, is isolated by fault element.
In prior art, Internal fuse mainly based on fine copper silk, needs the electric current of fusing to determine the diameter of fuse according to design.As it is shown in figure 1, Internal fuse interlude of the prior art is single round copper wire A, two ends are bifilar hank knotting winding structure B, and the bifilar hank knotting winding structure at Internal fuse two ends welds with element and bus-bar respectively.Generally fuse element length is constant, and the electric current that design fuses as requested is different, is changed the current-carrying capacity of fuse by the method adjusting fuse diameter.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus provides a kind of Copper Foil formula high-voltage capacitor Internal fuse, uses more reliable and more stable compared with traditional Internal fuse, easy to make.
The technical scheme provided according to this utility model, Copper Foil formula high-voltage capacitor Internal fuse includes fuse Copper Foil, the first fuse welding Copper Foil and the second fuse welding Copper Foil, it is characterized in that: fuse Copper Foil two ends connect the first fuse welding Copper Foil and the second fuse welding Copper Foil respectively, and fuse Copper Foil, the first fuse welding Copper Foil and the second fuse welding Copper Foil are flaky texture.
Further, the gauge scope of fuse Copper Foil is 0.01 ~ 0.5mm.
Further, the shape of cross section of fuse Copper Foil is rectangle.
Further, the shape of cross section of the first fuse welding Copper Foil and the second fuse welding Copper Foil is rectangle.
Further, fuse Copper Foil one end that fuse Copper Foil is single, single is connected to the first fuse welding centre position, Copper Foil end, and the single fuse Copper Foil other end is connected to the second fuse welding centre position, Copper Foil end.
Further, fuse Copper Foil is two, two fuse Copper Foils are distributed up and down, and two fuse Copper Foil one end are connected to the first fuse welding Copper Foil end upper-lower position, and two fuse Copper Foil other ends are connected to the second fuse welding Copper Foil end upper-lower position.
Compared with the prior art this utility model has the advantage that
This utility model simple in construction, compact, reasonable, under the conditions of fuse Copper Foil same cross-sectional area, the Copper Foil of square-section has bigger external surface area than the copper wire of circular cross-section, it is possible to reduce the impact of electric current kelvin effect, improves reliability；Internal fuse all uses the form being clipped in the middle of element, the thickness of Copper Foil is much smaller than copper wire thickness, use fuse Copper Foil to be conducive to controlling multiple element to gather into folds the gross thickness of the core body constituted, be also avoided that element or element insulating structure are caused deformation and damage by fuse；Fuse Copper Foil can use mould batch stamped, and technique is simple.

Description of reference numerals: 1-fuse Copper Foil, 2-the first fuse welding Copper Foil, 3-the second fuse welding Copper Foil, the single round copper wire of A-, B-bifilar hank knotting winding structure.
Detailed description of the invention
The embodiment combined in accompanying drawing is further described by this utility model below:
As shown in Fig. 2 ~ 3, this utility model mainly includes fuse Copper Foil the 1, first fuse welding Copper Foil 2 and the second fuse welding Copper Foil 3, fuse Copper Foil 1 two ends connect the first fuse welding Copper Foil 2 and the second fuse welding Copper Foil 3 respectively, first fuse welding Copper Foil 2 and the second fuse welding Copper Foil 3 are welding ends, and fuse Copper Foil 1 is welded with element and bus-bar by the first fuse welding Copper Foil 2 and the second fuse welding Copper Foil 3.
Described fuse Copper Foil 1 is flaky texture, the shape of cross section of fuse Copper Foil 1 is rectangle, the gauge scope of fuse Copper Foil 1 is 0.01 ~ 0.5mm, the width dimensions W of fuse Copper Foil 1 blowout current difference as requested changes, so that fuse failure performance meets design requirement.
Described first fuse welding Copper Foil 2 and the second fuse welding Copper Foil 3 are flaky texture, and the shape of cross section of the first fuse welding Copper Foil 2 and the second fuse welding Copper Foil 3 is rectangle.
In embodiment one as shown in Figure 2, described fuse Copper Foil 1 is single, single fuse Copper Foil 1 one end is connected to the first fuse welding centre position, Copper Foil 2 end, and single fuse Copper Foil 1 other end is connected to the second fuse welding centre position, Copper Foil 3 end.
In embodiment two as shown in Figure 3, described fuse Copper Foil 1 is two, two fuse Copper Foils about 1 are distributed, two fuse Copper Foil 1 one end are connected to the first fuse welding Copper Foil 2 end upper-lower position, and two fuse Copper Foil 1 other ends are connected to the second fuse welding Copper Foil 3 end upper-lower position.
The utility model has the advantages that: under the conditions of fuse Copper Foil 1 same cross-sectional area, the Copper Foil of square-section has bigger external surface area than the copper wire of circular cross-section, it is possible to reduce the impact of electric current kelvin effect, improve reliability；Internal fuse all uses the form being clipped in the middle of element, the thickness of Copper Foil is much smaller than copper wire thickness, use fuse Copper Foil to be conducive to controlling multiple element to gather into folds the gross thickness of the core body constituted, be also avoided that element or element insulating structure are caused deformation and damage by fuse；Fuse Copper Foil can use mould batch stamped, and technique is simple.
