Abstract
PURPOSE:To attempt the stabilization of insulation of the DC oil-filld apparatus by a method wherein plural insulating barriers are made to lap keeping to exist gap between each other and forming an oil gap between the inside wall of tank, the whole region of the inside wall is covered with the barriers and the dust existing in the oil is collected effectively. CONSTITUTION:The insulating barriers 7 consisted of an insulating paper like pressboard, etc., are provided being fixed with insulating spacers 6 at the inside wall of the tank 1 having the earth potential, the secondary insulating barriers 8 are provided making the mutual boundary parts to be lapped and keeping to exist a few oil gap, and both of the insulating distance between the inside wall of the tank 1 and the insulating barriers 7 at the tank wall side and of the insulating distance between the barriers 7 at the tank wall side and the secondary barriers 8 at the electric apparatus body side are made to be 10mm. or more and to be 100mm. or less. The depth D of the mutual lapping parts of the barriers 7, 8 are made to be 100mm. or more. By the simple constitution like this, the collection of dust in the insulating oil can be performed effectively.
