Abstract
The utility model discloses a high-pressure plastic rubber film capacitor, which is to solve the technical problems of reducing the inductance between the poles of the capacitor and enhancing the capability of withstanding the current; the capacitor takes the following techniques: a high-pressure plastic rubber film capacitor which is provided with capacitor slug inside of the housing, epoxy resin is filled between the slug and the housing, the capacitor slug is connected with an electrode lead wire, the slug comprises a plurality of aluminum foils which are arranged at intervals and overlapped and wrapped with dielectric films, and each of the aluminum foils is welded with an electrode lead wire along the length direction; all the electrode lead wires form a single electrode lead wire which is extended out of the housing. Compared with the existing technology, after a plurality of electrode lead wires are arranged in the aluminum foils, the inductance of the capacitor is reduced greatly; due to the current shunting effect of the multiple electrode lead wires, the capability of withstanding the current of the capacitor is enhanced greatly; meanwhile, since the capacitor is not sprayed with the mental layer or coated with tin and does not take the process of the encapsulating, clearing and welding, the manufacture cost is reduced.
Description
Technical field
The utility model relates to a kind of capacitor, particularly a kind of work film capacitor under high pressure.
Background technology
At present high pressure plastic film capacitor mainly contains two types on the domestic and international market: metalized film paper tinsel formula tandem type and paper tinsel formula tandem type also have the derivative type of indivedual similar said structures in addition.The rated operational voltage of this two kinds form height compression moulding glue film capacitor is between 630V to 3000V, exist volume big, production process is many, the shortcoming that cost is high, in order to alleviate the pressure on the cost, part producer brings into use paper tinsel formula thoughts type capacitor, replace paper tinsel formula tandem type capacitor, this paper tinsel formula thoughts type capacitor has the following disadvantages: the interpolar inductance is big, and contact conductor is drawn for the spot welding single line, and the withstanding current capability of capacitor is also very low.
Summary of the invention
The purpose of this utility model provides a kind of high pressure plastic film capacitor, and the technical problem that solve is to reduce the interpolar inductance of capacitor, improves withstanding current capability.
The utility model is by the following technical solutions: a kind of high pressure plastic film capacitor, in its shell capacitor core is arranged, infusion epoxy resin between capacitor core and the shell, capacitor core is connected with contact conductor, fuse is to be folded mutually and reel with deielectric-coating by the aluminium foil of space to form, described every layer of aluminium foil is welded with contact conductor at length direction, and it is that an electrode outlet line stretches out shell that contact conductor compiles.
Contact conductor of the present utility model is two to eight on each bar aluminium foil.
Aluminium foil of the present utility model has two-layer.
Deielectric-coating of the present utility model is a plastic film.
Plastic film between the utility model aluminium foil is one to ten layer.
Plastic film of the present utility model is polypropylene film or poly-second membrane of lipoprotein.
The capacitor core two ends of the utility model winding scribble epoxy resin.
Shell of the present utility model is an epoxy resin layer.
The utility model compared with prior art, after the built-in many contact conductors of aluminium foil compile, the inductance of capacitor descends greatly, because the electric current shunt effect of multi-electrode lead-in wire, the withstanding current capability of capacitor is improved greatly, simultaneously because do not adopt metal layer spraying or be coated with tin, seal, removing and welding process, so reduced the manufacturing cost of capacitor.
