The utility model discloses a power electronic detection device, and particularly relates to the field of line fault detection in a power-off power distribution network. The defect that no self-adaptive reclosing technology for the power distribution network exists in the prior art is overcome. Power electronic detection device, circuit comprising a thyristor, the thyristor circuit is composed ofsix thyristors. Every two thyristors are connected in series to form a bridge arm. The six thyristors form three bridge arms which are connected in parallel; one end of each of the three bridge arms is connected with one phase of power line in the three-phase power transmission circuit; wherein the connecting line is provided with a step-down transformer and a switch, a connecting line is led outbetween the two thyristors of each group of bridge arms, the three connecting lines are sequentially connected with a three-phase power line in a three-phase power transmission circuit through a step-up transformer, and each o
