Abstract：Through engineering case,the reliability design method of fire transfer pump control circuit of super high‑rise building is analyzed. In order to reduce the impact of pump failure water hammer on fire water supply system,the triangular‑star step‑down pump failure design is adopted for the star‑triangular step‑down start.
