The present invention discloses a breaker tripping prevention loop test method. The method comprises: when a breaker is located in a dividing position state, opening signals are continuously distributed to the breaker, closing signals are continuously distributed to the breaker, the closing signals are kept all the time until the energy storage of the breaker is finished, if the breaker only generates once closing and opening of the breaker in the whole process, the tripping prevention loop is qualified, and if the breaker generate multi-time opening and closing, the tripping prevention loop is not qualified; and after the tripping prevention loop is not qualified, the motion time of the tripping prevention relay of the breaker and the motion time of the auxiliary contact of the breaker are detected, and the motion times are subjected to comparison and analysis to determine the reason that the tripping prevention loop is not qualified. The motion time of the auxiliary contact of the breaker and the motion time of the tripping prevention relay of the breaker are analyzed to determine the reason that the tripping prevention loop is not qualified and suit the remedy to the case so as to allow the tripping prevention loop to play a reliable protection effect.
