Oil conservator for railway high-voltage traction transformer

The utility model relates to an oil tank structure for railway high voltage traction transformer, which belongs to the filed of transformer manufacturing technology. The utility model is composed of a lower oil tank (7) arranged in a double tank bottom (3) of a transformer, an upper oil tank (4) on the top of the lower oil tank (7) and a body in the upper oil tank (4); the body comprising a winding (1)and an iron core (2) is arranged on the plane of the double tank bottom (3) with its bottom, the iron core (2) falls inside the lower oil tank (7) and is wedge-caulked around by a wood block (16), the upper part of the iron core (2) is also provided with a high voltage upper clamping piece (8), a low voltage upper clamping piece (9), a positioning device (6) connected with the upper oil tank (4).The utility model makes the overall structure of the railway high voltage traction transformer more reasonable and each component fit tightly, ensure the tank and the body won't displace and being damaged during transportation and make it free of advanced suspended core checking after transporting to the site.
