Description
Technical field
The present invention relates to the capacitor class in the field of electrical components, is a kind of dry-type composite-dielectric filter capacitor specifically.
Background technology
Filtering capacitor is applicable to the voltage filter in the electron rectifier, as: fields such as the switching power supply in computer, TV, a series of electrical equipment, electric ballast, be to be composited by metallized polyester, polypropylene film material, zinc-aluminium base material micro materials, at present, filtering capacitor all adopts electrolytic capacitor both at home and abroad, some capacitors are made up of electrolyte, aluminium-foil paper etc., not only volume is bigger for it, loss is big, the power of Xiao Haoing is also big at work, and both positive and negative polarity is arranged, bring hidden danger for installation administration.Because of electrolyte is a kind of liquid existence, all can produce certain temperature in the electric appliance and electronic line work, its temperature is relatively all than higher, electrolytic capacitor is worked in hot environment for a long time, electrolyte evaporates gradually, electrolyte in electrolytic capacitor is dry, and capacitor will lose its effect, quits work.Also reduced the useful life of capacitor.
Summary of the invention
Problem to be solved by this invention just provides a kind of dry-type composite-dielectric filter capacitor, and withstand voltage height, volume are little, and it is little to consume energy, and the energy storage density height can bear bigger electric current.
In order to address the above problem, the present invention adopts following technical scheme: a kind of dry-type composite-dielectric filter capacitor, comprise capacitor body, pin and be coated on the embedding layer of capacitor body outside, it is characterized in that: described capacitor body is formed by polypropylene film that is coated with metal level and the superimposed successively coiling of metallized polyester film.
Further, described capacitor body is by the polypropylene film that is coated with metal level and metallized polyester film is superimposed successively and reel by no sensing mode and to form.
Further, described metal level is connected to form by aluminum metal layer and zinc metal level, and aluminum metal layer is an electrode surface, and the zinc metal level is a stiffened edge, and metallized film has " self-healing " characteristic, and loss is little, characteristics capacious.
Further, behind the superimposed coiling of polypropylene film and metallized polyester film, spray respectively to establish at an end face of end face of the metal level of polypropylene film and metallized polyester film and merge the gilding layer that forms, so that the welding extraction electrode by some kinds of metals.
As preferably, spray is established by zinc, antimony, tin, four kinds of metals of copper and is merged the gilding layer that forms respectively on an end face of end face of the metal level of polypropylene film and metallized polyester film.
Further, described polypropylene film and zinc-aluminium composite bed list stay the limit superimposed.
Further, described embedding layer is the epoxy resin cure layer.
Compare existing filtering capacitor, the fuse of capacitor of the present invention adopts the polypropylene film and the compound no-induction coiling of metallized polyester film that are coated with metal level to form, advantage is that dry type do not have oily structure, metallized film has " self-healing " characteristic, and loss is little, and capacity is big, and be regardless of both positive and negative polarity, the energy storage density height, conductive area is big, can bear bigger electric current; Isothermal curing epoxy resin carries out overall package, has both guaranteed the dielectric strength of capacitor, also guarantees the safe handling of capacitor under mal-condition simultaneously.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing;
Fig. 1 is a fuse coiling cross-sectional view of the present invention;
Fig. 2 is the structural representation of capacitor of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, dry-type composite-dielectric filter capacitor of the present invention, comprise capacitor body 6, pin 3 and be coated on the embedding layer 5 of capacitor body 6 outsides, described capacitor body 6 is reeled by polypropylene film 1 that is coated with metal level and metallized polyester film 2 compound no-inductions and is formed.Metal level is connected to form by aluminum metal layer 11 and zinc metal level 12, and polypropylene film 1 stays the limit superimposed with zinc-aluminium composite bed list, and aluminum metal layer 11 is an electrode surface, and zinc metal level 12 is a stiffened edge.Described embedding layer 5 is the epoxy resin cure layer.
After capacitor body 6 heat settings, spray respectively to establish by zinc, antimony, tin, four kinds of metals of copper at an end face of end face of the metal level of polypropylene film 1 and metallized polyester film 2 and merge the gilding layer 4 that forms, being convenient to capacitor core 6 welding extraction electrodes is pin 3.Because electric capacity produces heat at high temperature, big current work state, the too high then conductance of temperature is to capacitor generation thermal breakdown phenomenon, so extraction electrode is designed to special version, with gilding layer 4 bigger contact area arranged, and firm welding, be convenient to heat to deriving.Draw after pin 3 welding finishes, capacitor body 6 is gone in the particular manufacturing craft, carry out overall package with isothermal curing epoxy resin, both guaranteed the dielectric strength of capacitor, the while also guarantees the safe handling of capacitor under mal-condition.
After adopting above-mentioned embodiment, the advantage of this capacitor is that dry type do not have oily structure, metallized film has " self-healing " characteristic, the superimposed no-induction of metallized polyester film and metallized polypropylene film is reeled and is formed, and loss is little, and capacity is big, and be regardless of both positive and negative polarity, the energy storage density height, conductive area is big, can bear bigger electric current.
