ANTI-CLOGGING OIL CONDUIT

WIPO Patent Application WO/2016/177008

A1

The present invention relates to the technical field of an oil conduit of a transformer. Disclosed is an anti-clogging oil conduit, comprising a main pipe (1), a first branch pipe (2), a second branch pipe (4), and a third branch pipe (3) having an opening at one end. The first branch pipe (2) and the second branch pipe (4) are disposed on one side of the main pipe (1). The third branch pipe (3) is in communication with the first branch pipe (2) and the second branch pipe (4) and is parallel with the main pipe (1), and the end of the third branch pipe (3) having the opening faces downward. A first ball valve (2-1) is disposed in the first branch pipe (2), a second ball valve (4-1) is disposed in the second branch pipe (4), and a third ball valve (1-1) is disposed in the main pipe (1), wherein a removable filter screen (3-1) is disposed in the third branch pipe (3), and a sealing end lid (3-2) is disposed at the opening of the third branch pipe (3). By disposing a filter screen in the oil conduit to filter impurities, the anti-clogging oil conduit effectively addresses the problem of degradation of heat dissipation performance of the transformer caused by the accumulation of impurities over a long period of time in the oil conduit.
