Zusammenfassung:The invention relates to a split type low-pressure shaft end self-sealing system which comprises a rotor. The multiple steam sealing structures are arranged in the axial direction of the rotor, and gaps are reserved between the inner side walls of the steam sealing structures and the outer side wall of the rotor; the newly-enhanced steam pipeline is used for communicating an external steam source with the gap, so that external steam enters the sealing teeth to form a steam sealing curtain; each steam seal structure comprises a plurality of separated steam seal blocks, the separated steam seal blocks are arranged on the outer side of the rotor and form a complete ring, and gaps are reserved between the inner side walls of the separated steam seal blocks and the outer side wall of the rotor; the steam sealing sleeve is arranged on the outer side of the separated steam sealing block; and the newly enhanced steam pipeline is arranged on the separated steam sealing block and the steam sealing sleeve. The circumfer
