透しＫ＜い欠点があみ。As is well known, a resin film is exclusively used as the dielectric material of a capacitor, and is made of Elk. Due to the good tightness of the tube, the insulating oil impregnated in the tray can penetrate inside, which is a disadvantage.

が大倉ｉので、誘電体内部への浸ｊ１が困難であみ。Particularly, as an insulating oil, for example, A/*A/nabutalene bottles are widely used, which have a good pour point and a good surface tension and contact angle. Because of this, it is difficult to immerse the inside of the dielectric material.

絶縁油の浸透がＭい場合は、誘電体内１１１にボイドが
残存し耐圧性が低下すふなどの不都合は回避できたい。If the penetration of the insulating oil is slow, it is desirable to avoid inconveniences such as voids remaining in the dielectric 111 and a drop in pressure resistance.

If you show this, it will be filled with the following table. The sample capacitor (1) has a dielectric thickness of 1611 Wr in the following table Ilc.
t) A sheet of PP fiber A/A f'A is used (capacity αQl!+, IIF), and a test capacitor (2 sheets of insulating paper with a thickness of 1 mpm and a density α8f/, 4) and the One PP buoy shim with a thickness of 16# is inserted and stacked, and Marugame's (capacity α0211IF) is used.The voltage level of each voltage is shown as V7°.

In contrast to the case where the heating time is 15mm and the D-type is saturated,
When impregnated with Al oil, it is understood that it takes about 25 hours to reach saturation at t/%A.This is the surface tension that oil A and oil B give to PP Buisim.

ことが埋解されふ。The number of test units will be 411 units. From now on, 10% (1 unit) of test capacitors (1) impregnated with MuN oil will be destroyed when 0 days have passed after energization, and an additional 10% (1 unit) will be destroyed when 60 days have passed. Destroy the Lfh KW and impregnate it with A oil and B oil.
) shows that the ``-'' bonakatsueko was destroyed even after 140 days. 'This is because the oil is sufficiently impregnated to the inside for the reasons mentioned above, resulting in a long life and a long life.
