Summary:The utility model discloses a power cable overheating fault alarm device based on flexible thermoelectric sensors, which comprises an alarm lamp, a flexible thermoelectric sensor assembly and a lead,and is characterized in that the flexible thermoelectric sensor assembly is formed by alternately arranging a plurality of N-type flexible thermoelectric sensors and P-type flexible thermoelectric sensors and mutually connecting the N-type flexible thermoelectric sensors and the P-type flexible thermoelectric sensors through the lead; the positive electrode of the warning lamp is connected with the positive electrode of the flexible thermoelectric sensor assembly through a wire, and the negative electrode of the warning lamp is connected with the negative electrode of the flexible thermoelectric sensor assembly through a wire. The N-type flexible thermoelectric sensor and the P-type flexible thermoelectric sensor are I-shaped. When the power cable has an overheating fault, the I-shaped flexible thermoelectric sens
