Изобретение может быть использовано дл передачи электроэнергии по кабелю с плавучей электростанции особенно в районах Севера, где возможно обледенение.The invention can be used to transmit electricity via cable from a floating power plant, especially in areas of the North where icing is possible.

Известны опоры воздушной линии электропередач с траверсами, выполненными в виде балки, закрепленной к стойке опоры и имеющей элементы дл поддержани проводов til .Overhead transmission line supports are known with cross-beams made in the form of a beam fixed to a support post and having elements for supporting til wires.

Недостатком таких конструкций траверс вл етс затрудненность монтажа т желых кабелей и их прот жки по всей линии электропередачи.The disadvantage of such traverse designs is the difficulty of installing heavy cables and their pulling through the entire transmission line.

Наиболее близким техническим решением к изобретению вл етс опора линии электропередачи, включающа в себ стойку с установленной на не траверсой дл креплени кабелей 21 The closest technical solution to the invention is a transmission line support, including a rack mounted on a non-traverse for fastening cables 21

Такое устройство обеспечивает неизменную стрелу провеса провода, но нерационально дл компенсации изменени рассто ни между неподвижной опорой и плавучей электростанцией ввиду его громоздкости, особенно , когда через опору прот нут пучок кабелей.Such a device provides a constant sag of the wire, but it is not rational to compensate for the change in the distance between the fixed support and the floating power plant because of its bulkiness, especially when a cable bundle is pulled through the support.

Цель изобретени - облегчение монтажа кабелей больших диаметров и снижени материалоемкости опоры The purpose of the invention is to facilitate the installation of cables of large diameters and reduce the support material consumption.

Цель достигаетс тем, что опора линии электропередачи, содержаща стойку, с установленной на ней траверсой дл креплени кабелей, выполненной в виде объемного элемента, имеющего форму сектора в поперечном сечении и снабженного пазами дл The goal is achieved by the fact that a power line support containing a rack, with a cross-bar mounted on it, for fastening cables made in the form of a volume element, having a sector-shaped cross-section and provided with grooves for

Claims

Cables are 6 in them. Cable 6 is secured in working position with a collar 7. Supports 1 support cables b, which connect, for example, a floating power station 8 with a shore electricity consumer. One of the supports 1 is installed on the deck of the power station 8 and its traverse 2 is connected with C: winch 9 with the help of cable 10. Floating power station 8 under the action of wind load and flow-tidal character has a constant movement within the limits of the mooring device . In this case, the shape of the cable deflection line between the object and the first support is constantly changing. The first leg, as it were, transmits by means of cables fixed to it, the swing to the next leg, etc. Continuously changing the shape of the deflection line contributes to the splitting of ice and snow on the cable. If there is no movement of the power station 8, the traverse 2 can be swung by means of a winch 9, which is connected by a cable 10 to a support beam installed on the power plant's deck 8. Counterweight 4 contributes to maintaining the vertical position of the swinging yoke 2. The design of the yoke is simple to perform and allows you to eliminate the cable rhenium on the surface of the yoke when changing the deflection of the cable when moving the floating power plant and to ensure the release of the cable from ice and snow during icy conditions. Claim 1. Power line support, including a rack, with a cross bar installed on it for fastening cables, characterized in that, in order to facilitate installation of cables of large diameters / reduction of the support material capacity by reducing loads from ice and snow, the cross bar is made as a volume element having the shape of a sector in cross section and provided with grooves for laying cables and a pocket with rollers for moving the cable and installed with the possibility of its rotation relative to the stand along the line power lines. 2. Support POP.1, characterized in that the traverse is made with a counterweight. Sources of information taken into account in the examination 1. USSR author's certificate No. 538117, cl.
