Claims

[Scope of utility model registration request]

(1) An insulating margin part is provided at the widthwise end of the film to form an electrode, and an insulating groove is provided in at least a part of the vapor-deposited electrode in the width direction of the metallized film. In a dry metallized film capacitor formed by winding the capacitors in a stacked manner so as to face each other, forming electrode lead-out portions at both ends to form a capacitor element, and encasing the element, the film is made of a polyethylene terephthalate film, Capacitor element is 100-140
Dry metallization, which is constructed by heat treatment within the temperature range of °C, and is characterized in that when a dielectric film partially breaks down, vapor-deposited electrodes having insulating grooves are scattered in the length direction near the ends of the insulating margins. Phil-yun capacitor.

(2) A practical use characterized in that a plurality of the insulating grooves are formed in the width direction of the metallized film leaving a part of the vapor deposited metal, and the plurality of vapor deposited electrodes are connected to each other by the remaining vapor deposited metal. A dry metallized film capacitor according to claim 1 of the patent registration claim.

(3) The distance between the metal sprayed side end of the metallized film and the insulation margin side end of the opposing metallized form is within the range of 0.1 to 2.0 votes. A dry metallized film capacitor according to claim 1, which is characterized by:
