The invention relates to an explosion-driven multi-break circuit breaker, which is provided with a conductive plate, a detonating cord, a grain, a conductive barrel, a fracture area, an explosion chamber, a blocking ring and a supporting rod, the explosive column is arranged in the explosion cavity, and the cavity is filled with deionized water; high-energy explosives are arranged in the grain, and a high-speed detonator is arranged at the upper part of the grain and is detonated by an external detonating cord; the current-conducting plate is composed of an upper part and a lower part and is placed on the outermost side of the circuit breaker in parallel. The two ends of the conductive cylinder are tightly connected with the conductive plates, and the blocking ring installed on the periphery of the conductive cylinder is of a multi-fracture annular structure and is fixed between the upper conductive plate and the lower conductive plate through a supporting rod. The invention provides the multi-break circuit b
