いるのが一般的である。 Conventionally, metallized film capacitors have a structure in which electrodes are drawn out by thermal spraying metal on both end faces of a capacitor element made by winding a pair of metalized films coated with metal by vapor deposition.After being placed in a container, the capacitor element is heated and vacuum-dried. It is generally manufactured by methods such as impregnation with insulating oil.

が可能であるが、特に上記加熱真空乾燥、絶縁油
含浸が工程のネツクになつており、生産性の向上
を阻害している最大の原因となつている。 The metallized film capacitor constructed in this way has high withstand voltage performance, and it is possible to obtain a stable oil-immersed metallized film capacitor with a high corona onset voltage. This has become a major factor hindering productivity improvement.
この解決策として金属化フイルムコンデンサの

たり、金属化フイルムが劣化して破壊を起したり
する欠点があつた。 As a solution to this problem, non-impregnating metallized film capacitors have been proposed. However, since no insulating oil is impregnated, the corona onset voltage in particular is significantly lower than that of oil-immersed metallized film capacitors. It had the disadvantage of deteriorating and causing destruction.

A pair of metallized polypropylene films formed in this manner are stacked and wound with a widthwise offset from each other, and the winding hardness is measured using a durometer D of 68, 75, 77.5, and 85.
After metal spraying was carried out on both end faces of each capacitor element to draw out the electrodes, the element was placed in a case, filled with epoxy resin and cured, and the obtained dry metallized film capacitor with a capacity of 5 μF was heated at a temperature of 80°C. in
An AC voltage of 480V was applied continuously for 1000 hours, and then the capacitance was measured at an ambient temperature of 20°C and a measurement frequency of 1kHz. The results are shown in Figure 2.

サ。○ロはアルミニウム蒸着した有機フイルムを用
いた乾式金属化フイルムコンデンサ。 In addition, aluminum was vacuum-deposited on a polypropylene film with a thickness of 9 μm, and the resistance value of the deposited film was 2.
A capacitor element is formed by winding metallized polypropylene films of 4, 6 Ω/□ and 5, 9, 12, and 15 Ω/□ with vacuum-deposited zinc film resistance values, and the durometer D hardness of the element is 75 to 78 were housed in a case in the same manner as described above, filled with resin and hardened to obtain a dry metallized film capacitor. Figure 3 shows the results of capacitance and tanδ measurements after applying an AC voltage of 480 V continuously for 1000 hours at a temperature of 80°C to the thus obtained dry metallized film capacitor, and then measuring the capacitance and tanδ at an ambient temperature of 20°C and a measurement frequency of 1kHz. and shown in FIG. ○A is a dry metallized film capacitor that uses an organic film with vacuum-deposited zinc. ○B is a dry metallized film capacitor using an organic film deposited with aluminum.
上述のようにコンデンサ素子のデユロメータＤ
硬さが75以上で蒸着金属がアルミニウムのとき蒸
着膜抵抗は４Ω／□以下であれば容量減少を少な
くできた。 As mentioned above, the durometer D of the capacitor element
When the hardness was 75 or more and the deposited metal was aluminum, the decrease in capacity could be reduced if the deposited film resistance was 4Ω/□ or less.
一方蒸着金属が亜鉛のとき、基本的に容量減少
の点では問題ないが、第３図に示すように高膜抵
抗値になるほど溶射金属との接触抵抗が増すため
にtanδが高くなり好ましくない。したがつて蒸着
膜抵抗値は10Ω／□以下であることが望ましい。 On the other hand, when the deposited metal is zinc, there is basically no problem in terms of capacity reduction, but as shown in FIG. 3, as the film resistance increases, the contact resistance with the sprayed metal increases, which is undesirable as tan δ increases. Therefore, it is desirable that the resistance value of the deposited film be 10Ω/□ or less.
