Abstract
Disclosed is an aluminum electrolytic capacitor with high ripple current capability which is low in ESR value and low in heating value. The aluminum electrolytic capacitor comprises an outer casing, a core and electrolyte, wherein the core comprises positive and negative aluminum foil plate windings, out going lines and an insulating layer. The aluminum electrolytic capacitor is characterized in that the core comprises at least two pairs of positive and negative aluminum foil plate windings, the positive and negative aluminum foil plate windings in each pair are in parallel connection.
Description
Technical field
The utility model relates to a kind of aluminium electrolytic capacitor, especially a kind of aluminium electrolytic capacitor of large ripple current-resistant.
Background technology
Aluminium electrolytic capacitor comprises shell, core bag, electrolyte, its core bag comprises that as shown in Figure 2 the identical positive and negative aluminium foil pole piece of a pair of area is around volume 1,2, lead-out wire 3,4 insulation interlayers 5, known aluminium electrolytic capacitor only has a pair of positive and negative aluminium foil pole piece around volume 1,2, make that its ESR value is higher, caloric value is big, cause anti-ripple ability low, this is its shortcoming.
Summary of the invention
The aluminium electrolytic capacitor that the purpose of this utility model is to provide that a kind of ESR value is lower, caloric value is little, can large ripple current-resistant.
The technical scheme that its technical problem that solves the utility model adopts is: adopt at least 2 pairs of positive and negative aluminium foil pole pieces around volume.Positive and negative aluminium foil pole piece takes in parallel the coiling to make around volume, and every pair of positive and negative aluminium foil pole piece has identical positive plate area around volume, and the identical chaff riveted joint position of leading has identical metal impedance, makes that branch is even on the alminium electrolytic condenser internal current microcosmic.The rich structure of volume in parallel has obtained low ESR value, the ESR value be common product 1/2 or littler.Mechanism is that the aluminium electrolytic capacitor capacitance is and number (C1+C2+ when aluminium electrolytic capacitor is in parallel ... + Cn), and under the constant situation of capacity, can the broadening current path, electric conductivity is better.Can greatly improve the anti-ripple performance of aluminium electrolytic capacitor.Anti-ripple ability is more than 2 times or 2 times of common product.In same circuit, the aluminium electrolytic capacitor caloric value can be littler, and electric current is littler to the impact meeting of aluminium electrolytic capacitor, so electrical quantity is more stable.
The beneficial effects of the utility model are: the ESR value is low, be equal capacity capacitor 1/2 or littler; Caloric value is littler than the conventional aluminium electrolytic capacitor of equal capacity; Broadening current path, electric conductivity is better.Greatly improved the anti-ripple performance of alminium electrolytic condenser electrical equipment, anti-ripple ability is more than 2 times or 2 times of conventional aluminium electrolytic capacitor.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a prior art aluminium electrolytic capacitor core pack arrangement schematic diagram.
Among the figure: 1 is that positive paillon foil, 2 is that positive lead-out wire, 4 is the interlayer that insulate for bearing lead-out wire, 5 for bearing paillon foil, 3.
Embodiment
Referring to accompanying drawing, the utility model comprises shell, core bag, electrolyte, the core bag comprises positive and negative aluminium foil pole piece around volume 1,2, lead-out wire 3,4 insulation interlayers 5, and it is characterized in that: described core bag includes at least 2 pairs of positive and negative aluminium foil pole pieces around volume 1,2, and each is in parallel around volume to positive and negative aluminium foil pole piece.
In embodiment of the present utility model, it is 0.6g/cm that insulation interlayer 5 adopts density
3～0.75g/cm
3Electrolytic paper make, than conventional electrolysis paper density low 5%～40%.In addition, use conductivity to lure the electrolyte of electric energy power as the height of 1.6ms/cm～2.0ms/cm, the conductivity of more common product electrolyte is high by 5%～80%.Every electrical quantity of aluminium electrolytic capacitor can be guaranteed better, thereby the realization of the utility model purpose can be guaranteed better.
