Embodiment Construction
[0019] According to attached figure 1 and 2 It can be seen that the present invention relates to a guy wire system capable of alleviating the influence of guy wire slack. The guy wire system is applied to an eight-guy wire single-column UHV guy wire tower, which consists of a main column 2, a main guy wire 3 and an auxiliary guy wire 4. The middle position of the main stay wire 3 is connected with the auxiliary stay wire 4 in the horizontal direction, and all the auxiliary stay wires 4 are in the same plane, which is parallel to the foundation. When the main guy wire 3 is tightened, there is tension between the increased auxiliary guy wire 4 and the main guy wire 3, so that part of the tension potential energy on the main guy wire 3 is stored on the auxiliary guy wire 4, and the greater the tension of the main guy wire 3, the stored potential energy bigger. When the tension of the main guy wire 3 is loose for some reason, the potential energy of the whole guy wire system wil...

The invention discloses a stay wire system capable of relieving the influence of stay wire looseness and belongs to the technical field of stay wire tower stay wire systems in power transmission lines. The stay wire system specifically comprises a main stay wire arranged on an iron tower main pillar, one end of the main stay wire is connected with the upper middle portion of the main pillar, and the other end of the main stay wire is connected with a foundation. Pretightening force is exerted on the main stay wire, and auxiliary stay wires are arranged on the main stay wire. The two ends of each auxiliary stay wire are connected with the middle of the main stay wire, and all the auxiliary stay wires are located in the same plane which is parallel to the foundation. According to the stay wire system capable of relieving the influence of the stay wire looseness, when the main stay wire is loosened, the tension changing degree of the stay wire system is small compared with the situation that the auxiliary stay wires are not arranged, so that the tensioning degree of the stay wires can be adjusted, the influences on an iron tower by the looseness of the stay wires are effectively reduced, and the maintaining frequency is reduced.
Description
technical field [0001] The invention relates to the technical field of the cable tower cable system in the power transmission line. Background technique [0002] With the rapid development of the country's economic construction, it is urgent to transport the abundant thermal power, wind power and photovoltaic energy contained in the western region to the central and eastern regions. The UHV guyed tower has the advantages of simple structure, good mechanical performance, superior economic indicators, and convenient construction, and has a good application prospect. [0003] The guyed tower is generally composed of three parts: the tower head, the main column, and the guyed wire. The tower head and the main column are space truss structures composed of angle steel, which have good overall stability and can withstand large axial pressure. The guy wires are made of high-strength steel strands, which can withstand a lot of pulling force. The two parts of the structure take adv...
