Water -cooling oil -immersed transformer

The utility model discloses a water -cooling oil -immersed transformer, including sealed oil tank that sets up and the iron core of setting in the oil tank, the winding has the coil on the iron core, transformer oil is equipped with in the oil tank, iron core and coil submergence are in transformer oil, the outer winding of coil has the sleeve pipe, the intraductal pipe that is equipped with of cover, the pipe links to each other with the outer pump of oil tank, it has water -cooling liquid to lead to in the pipe. The outer sleeve pipe of pipe can seepage water -cooling liquid directly gets into the transformer oil in the oil tank after effectively having stoped the pipe to damage, has improved transformer oil's quality and has protected the insulating fibre, with the anti -aging. When pipe seepage water -cooling liquid, in water -cooling liquid can get into the gap of sleeve pipe and pipe, along with the outflow of pipe outer wall, staff's discovery had the water -cooling to flow out night, the timely pipe of more renewing.
