Description

Technical Field

[0001] The utility model belongs to the technical field of angle steel towers, in particular to a novel angle steel tower for power transmission lines. Background Art

[0002] Angle steel tower is a plate tower with downcomers. Its bubbling area is composed of angle steels arranged in parallel with each other. The angle steels are arranged in a direction parallel to the direction of liquid flow. The sharp edge of the angle steel is at the bottom, and the cross section is "V" shaped. There is a certain grid gap between two adjacent angle steels. The downcomer is the same as the general tower plate. The liquid on the upper plate flows into the "V" shaped angle steel through the downcomer, and the gas bubbles with the liquid when it rises through the grid gap to carry out the mass transfer process. The gas-liquid flow state on the tower plate is similar to that of the sieve plate. Angle steel tower plates have a small pressure drop, a large gas phase flux, a good tower plate efficiency, a simple structure, convenient processing and manufacturing, and good rigidity.

[0003] The strength of high-voltage cables is not enough to maintain them without deformation at this level. This determines that "vertical" is absolute and "straight" is only relative.

[0004] When the transmission distance is long, due to the deadweight of the conductor, a slight sag will be formed, making the conductor in the shape of a catenary. When the cable is sag, the height of the insulator needs to be adjusted to avoid the cable from sagging too low. For this reason, we propose a new type of transmission line angle steel tower.
