The utility model discloses a dry type power transformer anti-seismic device which comprises a base, the inner walls of the two sides of the base are each fixedly connected with three evenly-distributed limiting blocks, the middle positions of the four corners of the top of the base are each fixedly connected with a lower connecting block, and the middle positions of the inner walls of the limiting blocks are each fixedly connected with a limiting column. And first spring seats are fixedly connected to the middle positions of the two sides of the lower portion of the inner wall of the limiting block correspondingly, first springs are fixedly connected to the middle positions of the interiors of the first spring seats correspondingly, and the outer walls of the limiting columns penetrate through and are slidably connected with moving blocks correspondingly. According to the damping device for the dry-type power transformer, through linkage among a first spring seat, a third spring, a first spring, a second spr
