600V級以下のものにしか使用されていない。 Dry types are superior to impregnated types in terms of oil leakage, explosiveness, weight, etc., but those that use metallized film have problems with electrode thickness when used at high voltages. Partial discharge inception voltage is low for those using aluminum foil electrodes and dielectric material, and generally
It is only used for things below 600V class.

ンデンサを構成するようになしたものである。 Therefore, the present invention aims to use dry type capacitors at high voltages, and in manufacturing capacitor elements, a hot-melt film adhesive is used between the electrode and the dielectric material, and the capacitor elements are formed by hot pressing. A dry type capacitor is constructed using the following methods.
以下図面に示す説明図により説明する。 This will be explained below with reference to explanatory diagrams shown in the drawings.

たコンデンサ素子が成形される。 In the figure, 1 is a dielectric made of plastic film, 2 is a hot-melt film adhesive, and 3 is an electrode made of aluminum foil, for example. As shown in the figure, for example, a dielectric 1 made of plastic film is interposed between two electrodes 3; When the electrodes 3 and the dielectrics 1 are connected to each other, an insulating structure is used in which a hot melt film type adhesive is interposed between the electrodes 3 and the dielectrics 1 and between the dielectrics 1 so that the adjacent dielectrics 1 are sufficiently bonded to each other. and wind it around the winding core. When the capacitor element is then hot-molded using a hot press equipped with a mold, the hot-melt film adhesive is melted and a capacitor element is formed that completely fills all the gaps between the element layers.
