The invention discloses an intelligent type electric leakage protection method for a rural power grid power distribution terminal, comprising steps of setting a timing interruption inlet of a controller, sampling a phase voltage signal, a phase current signal and a leakage current amplification signal through an A/D converter, converting the sampled analog signal to a digital signal, performing comparison determination on the sampled leakage current digital signal and the leakage current limiting value which is set by the user and the time of the exceeding motion, if the detected leakage current exceeds the leakage current limiting value set by the user and the time of the exceeding motion, performing comprehensive determination according to the all operation states of the circuits by the controller and controlling the operation of the breaker, choosing the gain magnitude chosen by the leakage current measurement by the controller according to the leakage current limiting value set by the user in order to guarantee the relatively high measurement accuracy, and, if the detected leakage current does not exceed the leakage current limiting value set by the user and the time of the exceeding motion, directly suspending the timer and returning.
