The invention belongs to the technical field of polymerization kettle equipment, and particularly relates to a polymerization kettle top pipeline distribution table self-polymerization prevention system which comprises a polymerization kettle and three sets of kettle top pipeline distribution tables A, B and C. Each set of kettle top pipeline distribution table comprises a tee joint A, a tee joint B and a tee joint C which are connected to the top of the polymerization kettle and are correspondingly provided with nitrogen charging ports A, B and C respectively. The three nitrogen filling ports are respectively and correspondingly connected to a nitrogen main pipe through nitrogen branch pipes A, B and C, the nitrogen main pipe is externally connected to a high-pressure nitrogen system through a rotor flow meter and a nitrogen main valve, and a check valve and a needle valve are respectively and correspondingly arranged between each nitrogen branch pipe and the nitrogen filling port.
