The metallized plastic film capacitor of the present invention is made of two metalized plastic film capacitors formed by providing a safety function by providing a separation electrode made of a metal vapor deposited film on the surface of a dielectric film and providing a series of vapor deposited film blank areas. In a structure in which films are laminated and wound, the length of the metallized plastic film placed on the outside is longer than the length of the metallized plastic film placed on the inside within a range of 0.3% to 5% of the total length. , is characterized in that this extended part is tightly wound by applying tension.

It shows the relationship between the lengths of a and 5b. In a conventional capacitor of this type, the extension part 7 of the outer metallized plastic film 5b is
The length l was about 10 to 15 cm, but in the present invention, the length l is set to 100 cm, and it is tightly wound several times under sufficient tension. The length of this extension l varies depending on the length of L, but in short, it is sufficient as long as it can be wound tightly several times under tension, and is different from the conventional example. As shown in the figure, if the seam is less than 15cm, the tightening force will be insufficient, and if it is more than 250cm, it will be wasted. Therefore, the length of l is appropriately selected within the range of 0.3% to 5% of L.

As described above, in the present invention, since the extended portion 7 of the outer metallized plastic film 5b is tightly wound by applying tension, the non-uniformity of the electric field in this portion is eliminated, and the object of the invention is achieved. be able to. In order to confirm the effects of the present invention, a single-sided metallized plastic film made of polypropylene film was used to make a film with a diameter of 3.0 mm.
A capacitor A of the present invention (L=5000cm, l=100cm) and a conventional capacitor B ((L=5000cm, l=15cm) having a length of 3.0cm, a rated voltage of 200V, and a capacity of 8μF were created, and their characteristics When comparing (tanδ), the third
The results shown in the figure were obtained. As shown in the figure, it is clear that the capacitor A of the present invention has better characteristics than the conventional capacitor B.
