The invention discloses a spiral serial compact type multi-cavity arc extinguishing structure. The spiral serial compact type multi-cavity arc extinguishing structure is cylindrical as a whole, a plurality of layers of disc type structure units connected in series are arranged in the spiral serial compact type multi-cavity arc extinguishing structure, and the plurality of layers of disc type structure units rise spirally as a whole; each layer of disc type structure unit is composed of a plurality of metal spherical electrodes and semi-closed arc extinguishing cavities among the metal spherical electrodes; and the disc type structure units are connected through the tail end electrodes of the adjacent disc type structures, the head end electrodes of the adjacent layers and the semi-closed arc extinguishing cavities between the electrodes. Compared with a vertical series basic structure, the number of the arc extinguishing chambers can be increased in unit height, the overall arc extinguishing capacity of the s
