Abstract
The utility model relates to a high-voltage metallized polyester film capacitor which comprises a medium layer and a metallic film plated on a carrier. The utility model is characterized in that the carrier does not have insulating margins, the metallic film is an interval type film, and epoxy resin is impregnated into an insulating gap under the condition of vacuum and is solidified through high temperature. The utility model has the advantages that without the insulating margins, the gap at the edge is increased, which is favorable to the impregnation of the epoxy resin and can increase the insulating effect of the capacitor. Simultaneously, the consumption of polyester films is reduced, so that the producing cost of the capacitor can be reduced. By adopting the interval type metallic film, the inner series connection is realized to increase the electric voltage.
Description
The utility model is a kind of high-pressure metal polyester membrane capacitance, and particularly a kind of compartment plated film naked is stayed the high-pressure metal polyester membrane capacitance on limit.
The material that uses in the high-pressure metal polyester membrane capacitance generally comprises a layer dielectric and the interval membrane type metal film of one deck plating on carrier (deielectric-coating), and carrier has insulation and stays the limit.Roll into after the fuse, the space at edge is little, so when next process is epoxy resin impregnated, because the space at edge is less, usually cause epoxy resin can not soak, makes that the capacitor insulation effect is bad.
The purpose of this utility model provides a kind of novel capacitor, and it can overcome above the deficiencies in the prior art, improves the capacitor insulation effect.
The purpose of this utility model is achieved in that it comprises a layer dielectric and the metal film of plating on carrier (deielectric-coating), it is characterized in that carrier does not have insulation to stay the limit, the metal film that is coated on the carrier is the compartment metal film, in the insulation slit, vacuum-impregnated epoxy resin is arranged, and through hot setting.
The utility model has the advantages that: 1, do not stay the limit, the space at edge is increased,, can improve the insulation effect of capacitor so help the dipping of epoxy resin because carrier insulate.2, do not stay the limit owing to insulate, the materials of medium are reduced, so can reduce the production cost of capacitor.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is the side structure schematic diagram of the utility model metal film.
Fig. 3 is the end face structure schematic diagram of the utility model metal film.
Fig. 4 is the front view of the utility model metal film
5 is layer dielectrics among Fig. 1, the 4th, and carrier has been coated with metal film 3 on carrier, and 2 is flag paper tinsels among Fig. 1, the 1st, lead-in wire, the 6th, the epoxy resin of embedding.By Fig. 2 to Fig. 4 as can be seen, metal film 3 is a spacer film, and the limit is stayed on the both sides of carrier 4 not insulation.After rolling under vacuum condition through epoxy resin impregnated and through hot setting.Because the limit is not stayed in insulation, the space at its edge is increased, so epoxy resin impregnated effect is more satisfactory, the insulation property of capacitor can be greatly improved.
