The utility model provides a split twelve-pulse rectifier transformer which comprises a twelve-pulse rectifier transformer body, the interior of a low-voltage coil is divided into two layers, an air channel plate is placed between the two layers, and the low-voltage coil is divided into an upper low-voltage coil and a lower low-voltage coil which are the upper low-voltage coil and the lower low-voltage coil respectively. The head and the tail of the upper low-voltage coil and the head and the tail of the lower low-voltage coil are welded to the low-voltage inner lead copper bar and the low-voltage outer lead copper bar respectively, and the low-voltage inner lead copper bar and the low-voltage outer lead copper bar are arranged in a stacked mode. Practice proves that the twelve-pulse rectifier transformer structure is beneficial to assembly of the transformer, the upper and lower split winding outgoing lines are welded on the copper bar in the coil and are led out from the upper part, so that the short-circui
