The present invention relates to a Bipolar Discharge-Dissipation Lightning Air-Terminals, and an object of the present invention is to disperse and discharge an earth charge following a thundercloud approach in a space according to electric dipole, bipolar and electric double layer principle. The above object of the present invention is achieved by providing the bipolar discharge-dissipation lightning air-terminals comprising: a base member fixed and installed in a top region of a protected object, including a coupling projection on whose inner periphery surface coupling screw grooves are formed, the coupling projection protruded and formed at a side of an upper surface of the base member, and a grounding piece formed at a side opposite to the coupling projection in order to earth a ground electrode and a grounded lightning wire; a discharge member coupled releasably to the base member, for focusing an earth charge following a thundercloud approach on the upper surface of the base member; and a potential modifying unit attached releasably on the discharge member so that the potential modifying unit is charged with different charges by electric dipole, bipolar and electric double layer principle according to the thundercloud approach to disperse and discharge the earth charge in a space separated from the discharge member. |
