INSULATION OIL EXCHANGING METHOD AND INSULATION OIL EXCHANGING DEVICE FOR OIL FILLED CABLE CONNECTING PORTION

摘要

PROBLEM TO BE SOLVED: To provide an insulation oil exchanging method and an insulation oil exchanging device for an oil filled cable connecting portion, capable of facilitating exchange of the insulation oil filled in the cable connecting portion.;SOLUTION: In this insulation oil exchanging method for the oil filled cable connecting portion, while the insulation oil filled in the connecting portion is extracted in the amount to the extent of not producing negative pressure in the connecting portion, heated insulation oil is newly injected from an oil-pouring connector provided on the cable connecting portion, so that the insulation oil in a connecting pipe is exchanged. The insulation oil exchanging device for the oil filled cable connecting portion comprises: a connecting connector connecting an insulation oil inlet of the cable connecting portion; double tube piping connecting the connecting connector; an insulation oil discharging side connector connecting one of the double tube piping; and an insulation oil injecting side connector connecting the other one of the double tube piping, and by connecting the connecting connector to the insulation oil inlet of the cable connecting portion, the new insulation oil is injected from the insulation oil injecting side connector while the insulation oil to be exchanged is discharged from the insulation oil discharging side connector.;COPYRIGHT: (C)2005,JPO&NCIPI
