Definitions
- the invention relates to a film for a film capacitor, which is formed from an electrically insulating carrier film with an electrically conductive layer applied thereon, the electrically conductive layer in the film capacitor forming an electrode and the carrier film forming a dielectric.
- the invention further relates to a film capacitor made with such a film.
- Capacitors are manufactured for a wide range of capacities, among other things, as film capacitors, the dielectric consisting of a plastic film.
- the electrodes are formed from two conductive metal surfaces. These two metal surfaces consist either of thin metal foils or of metal layers evaporated onto the foils.
- the latter capacitors have a self-healing effect, i.e. in the event of an electrical breakdown or breakdown, the metal layer evaporates in the vicinity of the discharge or at a designated location in the vicinity thereof. This reduces the active area, and the capacitor can continue to be used, albeit with a slightly reduced capacitance.
- US5136462 and FR891 1713 describe films for a film capacitor which, instead of a continuous metal coating, have a metal coating divided into individual segments.
- the individual segments have a low surface resistance, they are separated from each other by non-conductive trench-like recesses and are only electrically connected to each other via narrow current bridges. These narrow current bridges serve as fuses which, in the event of an electrical breakdown, separate the affected segment from the other segments. Disconnect so that the damage caused by electrical breakdown is limited to a single or only a few segments.
- a capacitor with such a segmented film corresponds to several thousand individual capacitors connected in parallel.
- the cutouts between the segments are covered with a thin conductive layer.
- This serves to enlarge the active area and to avoid field elevations on the edges between electrode segments and uncoated cutouts.
- the purpose of the conductive cutouts is to increase the impedance in the vicinity of the latter in the event of an electrical breakdown in an electrode segment and to prevent the supply of energy.
- a film capacitor is known from WO 94/19813, which has a dielectric film with continuous electrodes vapor-deposited thereon.
- the electrodes are carefully designed to be relatively thin and have a correspondingly high surface resistance of 5 to 300 ⁇ . Thanks to the increased sheet resistance, an improved dielectric strength rsp compared to the segmented film capacitor described above. increased breakdown voltage achieved.
- the invention has for its object to provide a film for a film capacitor and a film capacitor provided with the film, which are only slightly subject to aging.
- the object is achieved by a film with the features of claim 1 and a film capacitor with the features of claim 8.
- Advantageous embodiments of the invention are characterized in the subclaims.
- the invention is characterized in that, in the case of a capacitor film with an electrically conductive layer as the electrode and a current path structure applied to the said layer, the surface resistance of the layer is as large as possible and that of the current path structure is chosen as small as possible.
- the first measure leads to a reduced loss of capacity in the event of a breakdown
- the second measure leads to a reduction in the overall surface resistance of the electrode and current path structure. This reduces the ohmic losses of the capacitor foil and thus its heating. Both of the measures mentioned thus have a positive effect on the signs of aging.
- the electrically conductive layer of the film according to the invention for a film capacitor has a relatively high surface resistance.
- this high sheet resistance limits the area at which the electrically conductive layer evaporates, as a result of which the effective electrode area and thus the capacitance of the capacitor are only slightly impaired.
- the breakdown voltage is increased and locally less electrical energy is converted into heat during breakdown.
- Providing a current path structure according to the invention, preferably in the form of main and secondary current paths results in a reduced overall surface resistance compared to the surface resistance of the electrically conductive layer. This reduced total area resistance reduces the ohmic losses in the current flow in the capacitor and thus the temperature increase in the capacitor and thus has a positive effect on its thermally induced aging.
- the current path structure preferably consists of the same or a different electrically conductive material as the electrically conductive layer and has a contour raised above the electrically conductive layer.
- the individual, preferably strip-shaped current paths are subdivided into main and secondary current paths and form electrode strips designed in strip form. structures
- the surface resistance of the current path structure is advantageously reduced by at least a factor of 20 compared to that of the electrically conductive layer. This allows a small coverage of less than 10% of the electrode layer by the current path structure without loss of the desired reduction in the overall area resistance.
- the narrower and / or less dense the current paths the less the reduction in the self-healing (high-resistance) electrode area of the capacitor foil. Due to the reduced total surface resistance and the thin electrode layer, a film capacitor provided with the capacitor film according to the invention has good electrical properties with optimal self-healing behavior, which results in increased life expectancy.
- Fig. 4 is a cross-sectional representation, not to scale, through a capacitor foil designed according to the invention.
- the film is composed of a carrier film 1 and an electrically conductive layer 2 applied thereon.
- the electrically conductive layer 2 is preferably designed as a metal layer, but electrically conductive plastic is also suitable for forming this layer.
- the carrier film 1, however, is made of an electrically insulating plastic material. It is also known to use a paper film as a carrier material.
- the film shown in FIG. 1 has a left longitudinal edge 3, along which the carrier film 1 is free of the electrically conductive layer 2, while the right edge of the film is provided with a main current path 4.
- the capacitor foil is contacted and fed from the outside over the entire length of this main current path.
- the current path structure composed of the main 4 and secondary current paths 5 has a lower electrical surface resistance than the electrically conductive layer 2, since it has a greater thickness than the layer 2. This is particularly clear from the illustration in FIG reference is made below.
- the electrically conductive layer 2 and the main and secondary current paths 4, 5 can be formed from a single metal coating and differ only in the thickness.
- the electrically conductive layer 2, which is preferably designed as a metal layer, and the current paths 4, 5 can also consist of different metals. It is e.g. expediently to form the layer 2 made of zinc and the main and secondary current paths 4, 5 made of aluminum, because the higher conductivity of aluminum means that the thickness of the main and secondary current paths 4, 5 can be kept small.
- main and secondary current paths 4, 5 consisting of a metal foil can also be used.
- the main and secondary current paths 4, 5 are preferably arranged in such a way that the electrically conductive layer 2 is subdivided into a plurality of partial regions 6, the extent of which is limited at least in one direction, so that the charge stored in the layer 2 is passed to the short path Main and secondary current paths 4, 5 can be derived.
- the secondary current paths 5 are spaced apart by a distance a, so that each point of the layer 2 is not further than a / 2 from the next current path.
- the shape of the partial regions 6 formed between the current paths 5 can be chosen as desired, for example strip-shaped, square, diamond-shaped, etc.
- the surface resistance of the electrically conductive layer 2 should be at least 5 ⁇ and preferably more than 20 ⁇ . The higher the surface resistance, the smaller the surface areas of the layers 2 forming the capacitor electrodes that are destroyed in the event of an electrical breakdown.
- a current path structure resting on the electrode layer is provided to reduce the total area resistance.
- a small degree of coverage in turn means a maximum expansion of the thinly coated self-healing electrode area, ie a minimal influence of the current paths on the self-healing qualities of the electrode.
- a desired coverage of less than 10% of the remaining electrode area is accordingly achieved by a few and / or narrow secondary current paths.
- the surface resistance of the electrically conductive layer is 70 ⁇ and the surface resistance of the current paths is 0.5 ⁇ . At a distance a of 3 cm, this results in a bypass path width of 0.1 cm and a film width b of 15 cm, a total surface resistance of 22 ⁇ averaged over different directions in the electrode area.
- the film capacitor with segmented electrodes explained at the outset has, for example, an area resistance of 7 ⁇ within each partial area. Due to the narrow current bridges, the total area resistance is increased by approximately 3.4 times, so that it is 24 ⁇ . Although the local sheet resistance in the known film capacitor is considerably lower than in the capacitor according to the invention, the total sheet resistance of the film according to the invention is lower than that of the film of the known capacitor.
- the film according to the invention and a capacitor formed from the film according to the invention are both optimized with regard to aging as well as with regard to their electrical properties.
- the distance a of the secondary flow paths can vary in the range from 2 to 15 cm and the width b in the range from 3 to 30 cm.
- the width of the secondary flow paths 5 is less than 10 mm and preferably less than 3 mm.
- both the electrically conductive layer 2 and the main and secondary current paths 4, 5 are formed from zinc, then the layer 2 has a thickness of less than 200 ⁇ and the current paths have a thickness of more than 4000 A. If the electrically conductive layer 2 made of zinc and the main and secondary current paths 4, 5 made of aluminum or a zinc / aluminum alloy are formed on the carrier film 1, the electrically conductive layer 2 has a thickness of less than 200 A and the current paths a thickness of more than 2700 A. As shown, a surface resistance ratio of more than 20 should be sought if possible.
- FIG. 2 shows a further exemplary embodiment of the film 1 according to the invention for film capacitors.
- This film essentially corresponds to that shown in FIG. 1 Foil, which is why the same elements are designated with the same reference numerals. It differs from this in that in the area of connection of the secondary flow paths 5 to the main current path 4, a tapering point 7 serving as a fuse is provided. This serves as an additional safeguard in the event of a non-self-healing electrical breakdown in the area of the current path 5.
- a capacitor according to the invention is either wound from two carrier foils coated on one side with a metal layer, the two metal layers each forming an electrode and the carrier foil consisting of plastic serving as dielectric insulation, or it is wound from a carrier foil coated on both sides with a metal layer and an uncoated foil , wherein the two metal layers form the electrodes and the additional uncoated film serves as an insulator.
- a cross-section results in a sequence of layers, each consisting of a dielectric insulating plastic material and a metal layer functioning as an electrode.
- the main current path on the opposite film edge is advantageously provided on every second single-coated film or on the back of each double-coated film. Then the secondary current paths shown in FIG. 1 alternately start from the right and left edges and each extend into a partial area 6 defined by the secondary current paths of the counterelectrode.
- FIG. 3 shows a view in which an additional secondary flow path 5 'runs parallel to the main current path within the film.
- the bypass flow paths 5 connect the bypass flow path 5 'to the main flow path 4.
- FIG. 4 shows a cross-sectional view through the film designed according to the invention.
- an electrically conductive layer 2 is applied using known coating techniques, which is designed as a metal layer, as shown in the previous exemplary embodiment.
- electrically conductive plastics can also be used for the electrically conductive layer 2.
- current path structures in the form of main and secondary current paths 4, 5 are provided, which are either formed in one piece with the electrically conductive layer 2 or subsequently applied to the layer 2.
- the current path ad structures are preferably designed as strips 4, 5 running on the surface and connected to the layer 2 in an electrically conductive manner.
- the thickness of the main and secondary current paths 4, 5, which are designed as strips, increases their thickness, as a result of which the electrical surface resistance to the resistance within the electrically conductive layer 2 is reduced.
- the carrier film can be formed from polypropylene, polystyrene, polyester, polycarbonate, PET, PEN, cellulose acetate or lacquer film; the metal layer and the current paths can be formed from zinc, aluminum, silver, gold, copper, magnesium or an alloy of several of these metals; Instead of the high-resistance metal layer, an electrically conductive plastic layer can also be provided.
- the shape of the film does not have to be strip-shaped, but can take any shape as required.
- the current paths in particular the secondary current paths, can be designed with a gradient in their resistance value. This resistance gradient can be changed by changing the composition, the width and / or the thickness of the the current paths are provided.
- the secondary current paths 5 are preferably designed with a resistance value that decreases in the direction of the respective main current path 4. In these cases, the desired surface resistance ratio between the current path structure and the electrode layer relates to the thickest point of the secondary current paths.
