The invention relates to an integrative protector of an intelligent power grid terminal, which not only has the protective functions of overload, short circuit, overvoltage, undervoltage, electric leakage, automatic tracking of the electric leakage and the like but also has the integrative functions of adjustable operating value of the electric leakage, adjustable operating value of overcurrent, three-time automatic reclosing and the like. The integrative protector of the intelligent power grid terminal also has the functions of displaying and transmitting of the data of single-phase current, single-phase voltage, leakage current and the like and tripping fault alarming. The integrative protector of the intelligent power grid terminal also has the function of intelligentizing and networking management of a low-voltage power grid terminal of remote measurement, remote communication, remote control, remote adjustment and the like. The integrative protector of the intelligent power grid terminal comprises a plastic casing with high flame retardant, a main circuit, an auxiliary power supply circuit, a zero-sequence mutual inductor, a voltage sampling circuit, a manganese-copper split-stream sampling circuit, a data comparing and parameter adjusting circuit, a single chip microcomputer (U3), a light emitting diode (LED) display circuit, an alarm circuit, a remote control communication interface and an electric automatic reclosing circuit.
