20080246010 | Apparatus And Method For Enhancing The Reconductoring Of Overhead Electric Power Lines - Equipment and associated methods for replacing existing overhead transmission line conductors with new ones while the transmission line remains in service and carrying power. The old conductor is used to pull the new conductor through a series of sheaves installed at the bottom of the insulator at each tower. Conventional tension-stringing equipment is used but it is elevated to line potential that is achieved by use of an insulating platform or insulating jacks. Current transfer between stationary and moving conductors is achieved by a current transfer device that may consist of transmission line contacting wheels and liquid metal contactors. Sag control in various conductor spans is enhanced by a stringing block with controllable friction. Equipment is also introduced which will prevent release of the conductor by the pulling device should it break while engaged by that device. | 10-09-2008 |
20090095522 | Robotic Bypass System and Method - A system and method, and robotic equipment for mechanical and/or electrical bypassing of short sections of energized high voltage line conductors by gripping the conductor at two close-by points, making good electrical and mechanical connection, then drawing the two points towards one another so as to relieve both mechanical and current-carrying duty of the bypassed conductor section. Doing so can provide slack on the bypassed conductor section for maintenance or repair while simultaneously providing an alternative path for electric current, or increase tension on the adjacent conductor sections by essentially shortening the conductor in the region where the invention is applied. The invention may then reverse direction, placing (stretch) tension on the bypassed conductor section and the point of repair to assure its mechanical integrity. Mechanical bypassing only to temporarily shorten specific conductor spans may be achieved by the same device. Electrical bypassing only may be achieved in a similar manner by gripping and bridging two separate high voltage conductors, thus providing a means to connect and/or disconnect them with the aid of switching equipment incorporated into the invention. The invention allows all of the foregoing to be accomplished at line potential and in close line proximity by virtue of its being mounted on an insulated boom or suspended from a hovering helicopter or suspended from the line itself. | 04-16-2009 |
20090295235 | In Situ Reconstruction of High Voltage Electric Power Lines - A method for creating working space for construction of a new high-voltage transmission line within an existing three phase high voltage transmission right of way without removing the existing three-phase high voltage transmission line already occupying that right of way from service. The method includes removing the voltage applied to one phase of the existing transmission line, continuing to transmit power on the conductors comprising the remaining phases, and installing new support structures and their associated conductors on the right of way while the existing transmission line continues to operate. | 12-03-2009 |
