摘要： A plurality of capacitors of the type each including capacitor elements with a very small gap between adjacent electrodes are filled and impregnated with a capacitor oil with the aid of a capacitor oil filling/impregnating apparatus. The apparatus comprises an impregnating chamber including a capacitor oil supplying portion, a charging/discharging platform having a plurality of capacitors placed thereon, and distributing/supplying means arranged above the charging/discharging platform so as to allow the capacitor oil to be supplied to the respective capacitors from above by its free falling-down induced by a dead weight of the capacitor oil itself. A capacitor oil filling/impregnating method is practiced with the aid of the foregoing apparatus by way of the steps of heating the interior of the impregnating chamber under a high level of vacuum to dry the respective capacitors on the charging/discharging platform, cooling the capacitors after completion of the drying operation, supplying the capacitor oil to each capacitor from a capacitor oil refining/supplying system via the capacitor oil supplying portion, keeping the capacitors still for a predetermined period of time after completion of the capacitor oil supplying operation, and allowing the capacitors to be impregnated with the capacitor oil.
