Abstract
PURPOSE:To enable the device in the caption to enclose oil drops ascended from an oil tank into a balance chamber by centrifugal force of a radial step on the rotary shaft by providing the step on the rotary shaft at an upper portion adjacent to an intake chamber of a seal box, and providing the balance chamber so that it strides over the step. CONSTITUTION:A seal box 6 surrounding an oil tank 5 consists of a balance pipe 7 connecting a balance chamber 10 of the seal box 6 to a positive pressure chamber in a rotary electrical apparatus, an intake pipe 8 connecting an intake chamber 11 to the positive pressure chamber in the rotary electrical apparatus, and an exhaust pipe 9 connecting an exhaust chamber 12 to the outside of the rotary electrical apparatus. A radial step is provided by making a rotary shaft diameter opposed to the balance chamber 10 smaller than the rotary shaft diameter opposed to the intake chamber 11 and the exhaust chamber 12, the balance chamber 10 being provided so that it strides over the step.
