In order to achieve the purpose, the column base of the transformer substation voltage transformer support comprises a steel pipe column, a foundation structure, foundation bolts and a column base bottom plate, and is characterized by further comprising adjusting nuts and fastening nuts;
the bottom of the steel pipe column is welded on the column base bottom plate;
the tops of the foundation bolts penetrate through corresponding positions of the column base bottom plate, fastening nuts are screwed on the foundation bolts on the column base bottom plate, and adjusting nuts are screwed on the foundation bolts below the column base bottom plate;
and the whole or the bottom of the foundation bolt below the adjusting nut is embedded in the foundation structure.
Furthermore, at least one bolt backing plate is arranged between the column base bottom plate and the fastening nut and/or between the column base bottom plate and the adjusting nut according to the heightening requirement.
Further, a secondary grouting layer is arranged between the column base bottom plate and the foundation structure.
Further, the thickness of the secondary grouting layer is 50 mm.
And the rubber protective sleeve is sleeved outside the top of the foundation bolt and a fastening nut below the foundation bolt.
Further, the steel pipe column comprises a plurality of stiffening plates which are uniformly arranged along the periphery of the steel pipe column; the stiffening plate is fixed between the steel pipe column and the column base bottom plate.
Further, the top of the base structure protrudes above the ground by at least 150 mm.
Further, the basic structure is in a step shape. Further, the secondary grouting layer is arranged on the outer surface of the upper step of the foundation structure in a covering mode.
Compared with the prior art, the utility model has more convenient construction under the condition of equal installation precision of the electrical equipment; the foundation bolt is matched with the adjusting nut and the fastening nut, so that the deviation of the foundation bolt and a foundation structure after forming is ensured, the alignment and elevation calibration of the steel pipe column are facilitated, and the disassembly and secondary transformation are also facilitated; furthermore, the column base of the steel pipe column is exposed, so that potential safety hazards are easy to find, and secondary transformation is facilitated.
