パラフィンの混入率は約６０重量％程度となっている。BACKGROUND OF THE INVENTION FIG. 2 shows a schematic structure of a conventional metallized film capacitor confectionery section. 11 is a polyolefin film such as polypropylene or polyethylene, and 12 is a vapor deposited film formed on one side of the film 11. A metal such as aluminum or zinc is used as the vapor-deposited metal. 13 is a metallicon layer for leading out the electrodes. Furthermore, in conventional wax-impregnated type capacitors, a mixture of paraffin wax, polybutene oil, polyethylene oligomer, etc. is used, and the concentration of normal paraffin in the impregnant is about 60% by weight. There is.

が困難である。Problems to be Solved by the Invention However, in the conventional structure described above, since the dielectric material and the electrode are made of a single-sided metalized polyolefin film, the number of man-hours required to form the metal evaporated film is large, and as a result, the capacitor The disadvantage is that the element cost is high. Therefore, attempts have been made to metallize both sides of a polyolefin film. However, if a conventional impregnating agent containing normal paraline of 60% by weight or more is used for a capacitor that has a double-sided metalized polyolefin film and a laminated film, the capacitor made of a conventional single-sided metalized polyolefin film It is difficult to obtain the same level of performance as those impregnated with conventional impregnating agents.

。従って電気的劣化が少なくなる。Function When paraffin wax (and a portion of polybutene-based insulating oil) is used in a capacitor having a double-sided metalized polyolefin film and a laminated film, the film swells and its volume increases. However, when the double-sided metallized polyolefin film and the laminated film are made of different materials as described above, their swelling properties are different, resulting in dimensional changes between the two, and as a result, voids are generated. The generation of voids is suppressed by keeping the mixing rate of normal paraffin below a certain value. Therefore, electrical deterioration is reduced.

った。Reference numeral 6 denotes an impregnating agent, and in the configuration shown in FIG. 1, the life characteristics of the capacitor vary depending on the type of impregnating agent. In particular, if the vapor deposited film and the laminated film have different swelling properties, there will be a large difference in life characteristics. Table 1 and FIG. 3 show comparisons of the characteristics of capacitors when polypropylene was used as the laminated film and the mixing ratio of normal paraffin as an impregnating agent was varied. Note that the capacitor sample was 60 μF, and the trial application was conducted at 60° C. and 300 V.

る。Table 1 According to Figure 3 and Table 1, the contamination rate of di-normal paraffin is 40.
Those with less than 60% by weight (Examples 1 to 3) satisfy the JIS standard, and those with 60% by weight or more (Comparative Examples 1 to 3) do not meet the standards and cannot be put to practical use. When the mixing rate of normal paraffin in the impregnating agent increases, the swelling of the polyolefin increases, and wrinkles occur in the laminated film, which has a large dimensional difference due to swelling between the vapor-deposited film and the laminated film, which causes voids. When a voltage is applied between the electrodes, corona discharge occurs, causing deterioration of the insulating material and oxidation of the electrode film, resulting in a decrease in capacity.
