The invention relates to a three-phase wire current detection device with an odor generator. Induction devices, energy storage circuits, a logic circuit and an output device are connected in series insequence. Each induction device is used for sensing a magnetic field of an electric wire to generate an electric charge; each energy storage circuit is used for storing the generated charge; the logic circuit is used for controlling the detection device; and three groups of induction devices and three groups of energy storage circuits are arranged. A built-in phase comparison module is arranged in the logic circuit and is connected with the three groups of induction devices and three groups of energy storage circuits respectively. One energy storage circuit is also electrically connected withthe logic circuit. The output device is an odor generator. The current of the three-phase wire is detected to determine whether the current is abnormal. With the odor generator, the user still can pay attention to the current abnormity in a noisy and chaotic environment. Besides, the detection device has the small size and can be applied to a high-voltage wire with good environment protection effect and high security.
