摘要： Provided are methods and systems for forming piezoelectric coatings on power line cables using sol-gel materials. A cable may be fed through a container with a sol-gel material having a piezoelectric material to form an uncured layer on the surface of the cable. The layer is then cured using, for example, infrared, ultraviolet, and/or other types of radiation. The cable may be suspended in a coating system such that the uncured layer does not touch any components of the system until the layer is adequately cured. Piezoelectric characteristics of the cured layer may be tested in the system to provide a control feedback. The cured layer, which may be referred to as a piezoelectric coating, causes resistive heating at the outer surface of the cable during vibration of the cable due transmission of alternating currents and environmental factors.

摘要： An apparatus and a method are for varying an impedance of a phase line of a segment of a first electrical power line, the phase line including n conductors electrically insulated from each other and short-circuited together at two ends of the segment. The apparatus includes at least one controllable switching device for connection with at least one of the conductors. The apparatus also includes a controller for performing control of the at least one controllable switching device, the controller having at least one optical port for receiving first optical signals on which the control is based, and for sending second optical signals to adjacent switching apparatuses, the second optical signals including status information of the one switching apparatus, upon which control of adjacent switching apparatuses is based.

摘要： A helicopter (4) carries a generally horizontal beam (6) that extends transversely to the longitudinal axis of the helicopter (4). The beam (6) carries along its length a plurality of mutually spaced magazines (7) for housing flexible cables (8) that can be fed-out to hang down from respective magazines (7) and taken back into said magazine. As the helicopter (4) flies along a power line construction (1), the cables hang down between and outside the power lines (12) of said construction (1), so as to work mechanically on the lines (12) such as to remove snow, ice and water therefrom, at same time as the airstream form the main rotor (41) of the helicopter (4) acts on the power line construction (1) and the cables (8).

摘要： A coating (626) comprising a ferroelectric, lossy dielectric, ferromagnetic or semiconductor material is disposed near an object (620). AC current flows through an electrical conductor (624), creating an electromagnetic field. The coating (626) absorbs energy from the electromagnetic field, thereby generating heat, which melts snow and ice on the object (620).

摘要： The invention concerns a switching apparatus designed to be used with an electric power transmission line section comprising several phase lines. Each of the phase lines includes several conductors electrically insulated from one another and connected in parallel. The conductors of each phase line are mutually shorted out at two ends of the section. The apparatus comprises pairs of switches connected in parallel, for selectively opening and closing each phase line conductors, a sensing device for detecting the section current operating conditions, and a control device for controlling the switch pairs based on the section current operating conditions. The invention also concerns a switching method.
