Support-end-free outgoing line framework for 330kV transformer substation

The utility model discloses a support-end-free outgoing line framework for a 330kV transformer substation, and relates to the technical field of power transformation engineering. The structure comprises a plurality of herringbone column frameworks, rigid shearing force supporting columns and framework beams. The multiple herringbone column frameworks are symmetrically arranged with the rigid shear force supporting column as the center and are arranged on the same horizontal line at intervals. The framework beams are connected between the top ends of any two adjacent herringbone column frameworks, and the framework beams are also connected between the top ends of the two herringbone column frameworks adjacent to the rigid shearing force supporting columns and the top ends of the rigid shearing force supporting columns; the rigid shear supporting column comprises a first herringbone column, a second herringbone column and a connecting assembly, and the first herringbone column and the second herringbone column
