Low-voltage lead structure of three-phase five-column mining transformer

The utility model relates to a transformer winding lead structure, in particular to a low-voltage lead structure of a three-phase five-column mining transformer, which solves the technical problems in the background technology and comprises an upper clamping piece and a lower clamping piece. The first transverse lead copper bar is fixedly connected to the upper clamping piece through a wooden comb type wire clamp, the tail end of the three-phase winding is connected with the second transverse lead copper bar, the second transverse lead copper bar is fixed to the lower clamping piece through a wooden comb type wire clamp, and a vertical lead copper bar is connected between the first transverse lead copper bar and the second transverse lead copper bar. The vertical lead copper bars are located at the corresponding positions of gaps between the adjacent windings respectively, the three first transverse lead copper bars are connected with copper strips respectively, and the free ends of the copper strips are conn
