Abstract
The utility model relates to a composite medium capacitor which comprises capacitor cores. The utility model is characterized in that the capacitor cores are formed by rolling polyester films, polypropylene films and electrode materials in a parallel connection mode. Compared with a polycarbonate capacitor or a polyphenyl thioether capacitor in the prior art, the utility model has the advantages that medium materials have low cost, high capacity accuracy can be achieved by connecting in parallel and matching the cores with different volumes, and the zero deflection of the temperature stability of capacitor volume can be realized by volume matching through the theoretical calculation in different temperature spots so as to achieve high accuracy and stability.
Description
Technical field
The utility model relates to a kind of electric elements, all good composite dielectric capacitors of particularly a kind of electric capacity precision and stability.
Background technology
Polycarbonate capacitor has good electric capacity stability, be widely used in national defence and some special occasions, but the dielectric material Merlon costs an arm and a leg and stopped production at present basically, can substitute the polyphenylene sulfide that has only of this dielectric material from the technical parameter, but this material self-healing performance is bad, causes electrical breakdown easily and loses efficacy.Therefore need a kind of new dielectric material of searching badly and substitute the electric capacity that the above-mentioned material making has good stability.
Summary of the invention
The purpose of this utility model is just at existing weak point in the above-mentioned prior art, adopts that the substitute medium manufacture of materials is a kind of to have precision height, a composite dielectric capacitor that capacity stability is good.
The purpose of this utility model can realize by following technique measures:
Composite dielectric capacitor of the present utility model comprises capacitor body, and described capacitor body is to be reeled in the mode that is connected in parallel by polyester film, polypropylene screen, electrode material to form.
Capacitor body described in the utility model is by the metallized polyester film that electrode material layer is arranged in polyester film substrate layer surface attachment and has the metallized polypropylene film of electrode material layer to reel in the mode that is connected in parallel in polypropylene screen substrate layer surface attachment to form.
Capacitor body described in the utility model is to be formed by the polypropylene rete that stacks successively, electrode material layer, polyester rete, the in parallel coiling of electrode material layer; And two electrode material layers are stacked together in the mode that the edge interlaces.
Capacitor body described in the utility model also can be to be formed by metallized polypropylene film layer that stacks successively and in parallel coiling of metallized polyester rete.
Capacitor body described in the utility model can also be that the fuse that the fuse of being reeled by a polyester film and electrode material and polypropylene screen and electrode material are reeled is made by the combination of parallel connection outside; Certainly also can be following frame mode, promptly described capacitor body is to be made by the combination of parallel connection outside by the fuse of the fuse of a metallized polyester film coiling and a metallized polypropylene film coiling.
The utility model is compared with the Merlon of prior art or with the polyphenylene sulfide capacitor, has following advantage:
1. dielectric material is with low cost;
2. can reach very high capacity precision by the collocation in parallel of the fuse of different capabilities;
3. carry out the zero-deviation that the capacity collocation can realize the condenser capacity temperature stability at different temperature spots by Theoretical Calculation, reach quite high precision and stability.
