The invention discloses a magnetic spring Brandon steam seal. The magnetic spring Brandon steam seal comprises a plurality of steam seal bodies, wherein the end faces of both sides of arc-shaped segments of the steam seal bodies are provided with drilling holes; magnets are arranged in the drilling holes; the magnets arranged the end faces of adjacent steam seal bodies have the same magnetic poles, and repel each other. Under the different working conditions, automatic adjustment change of steam seal gaps are kept through the balance of steam pressure on the back of the steam seal and magnetic force of the magnets, so that the effect of considering unit security and economical efficiency is achieved. By adopting the magnetic spring Brandon steam seal, the problem of failure and jam fault in a mechanical spring is solved, the steam seal gaps are kept small constantly, and high sealing effect persistence is realized.
