The invention relates to a high-frequency harmonic absorbing device. The device comprises a gas discharge tube, a high frequency absorbing circuit, an oscillation suppression loop and an indicating circuit, a circuit parallel connection mode is adopted, the whole device is connected between a phase line L and a midcourt line N through fuses, the gas discharge tube, the high frequency absorbing circuit and the oscillation suppression loop are connected in parallel, and the indicating circuit in connected in the oscillation suppression loop in parallel. The device has an inhibiting effect to high-frequency harmonic and high-frequency noise which are generated by electric equipment, and meanwhile the device restrains transient signals and surge signals in a power grid. The parallel connection mode is adopted, and the field installation is convenient.
