Abstract

PURPOSE: For raising the electrical reliability of super ultrahigh transformers, to make the removal of the dust contained in oil by inserting an oil filter, a partition valve, and a discharge valve in the piping of the external cooler provided on an internal device casing oil tank.
CONSTITUTION: An upper piping 15 and a lower piping 16 are attached in the oil tank 1 having a conservator 1, and a cooler 4 is fitted therebetween. Oil is circulated in said tank 3 by an oil pump 7. An oil filter 12 made of 100W300 mesh wire gauze and a partition valve 13 are provided between said cooler 4 and pump 7, and further a discharge valve 14 is fitted between said filter 12 and partition valve 13. Cooling is made with oil circulated from the lower side of the transformer coil encased in said tank 3. Thereby, the removal of the dust having attached to said coil and the discharge of captured dust are facilitated so that reliability is raised.
