PURPOSE:To eliminate the need for lubricating work at the time of assembly at sites, and to simplify assembling work by a method wherein a pressure discharge pipe is removed, the inside of a fitting joint for the pressure discharge pipe is filled up with insulating ol and the apparatus is transported. CONSTITUTION:A valve 13 between the conservator 3 and a proper tank 1 is closed, and the insulating oil in the pressure discharge pipe 5 is extracted from an oil discharge valve 11 until an oil surface lowers up to the inside of the fitting joint 4 for the pressure discharge pipe. The pressure discharge pipe 5 is removed, a blank cap 22, to the inside thereof an oil discharge section is formed, is attached to the joint 4, the valve 13 is opened, the insulating oil in the same quantity as the insulating oil previously extracted is lubricated into the conservator 3, and the apparatus is transported. The valve 13 is closed and the blank cap 22 is removed at sites. The insulating oil in the joint 4 does not overflow by the oil discharge section mounted to the blank cap 22 at that time. The pressure discharge pipe 5 is fitted, the valve 13 is opened and the insulating oil is moved into the pressure discharge pipe 5 from the conservator 3. Accordingly, lubricating work at the time of assembly at sites is unnecessitated, and assembling work can be simplified. |
