<p><P>PROBLEM TO BE SOLVED: To provide the tip structure of an insulated control rod which prevents unexpected dropping of a hermetical stopper member for a terminal cover of a ground short-circuit terminal to facilitate and ensure the safety of ground short-circuit work on an electric line. <P>SOLUTION: A tip setter 10 is used for attachment of an insulated control rod to/from which a hermetical stopper member is attached/detached, the hermetical stopper member blocking an opening of a terminal cover of a ground short-circuit terminal disposed in advance on a special-high-voltage electric line. The tip setter 10 includes a cylindrical portion 11 in which the terminal cover is set and a projected-shape portion 21 which is attached to the inner surface 11a of the cylindrical portion 11 to project inward. The projected-shape portion 21 is composed of a seal portion 22 attached to the inner surface of the cylindrical portion 11 and a curved-shape portion 23 which projects from the seal portion 22 to curve toward a bottom face 12 and is warped by a disc member of the hermetical stopper member moving inside the cylindrical portion 11, the seal portion 22 and the curved-shape portion 23 being formed integrally together. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
