The invention relates to the technical field of power grid early warning, in particular to a power grid power failure risk early warning system. The power grid power failure risk early warning system comprises an early warning center and a plurality of monitors, the monitors are used for monitoring cables around a power grid trunk line, and the early warning center is used for analyzing and displaying data monitored by the monitors and controlling the monitors. According to the invention, the displacement sensor is used for detecting the swing amplitude and swing frequency of the cable under external force, the wind speed sensor is used for monitoring the wind speed condition of the position, the tension sensor is used for measuring the external force on the cable, and the sensors are used for detecting the influence of natural external force on the safety of the cable. Then the current of the cable is measured through the Hall current sensor, and the influence of the load on the line safety is monitored, so
