Research On Tower And Overhead Line Technology Of660kV DC Transmission Project

The investment of Direct-current transmission tower and stringing will cost a hugeamount of man power, materials and energy. The key of ensure transmission projectcompleting on schedule is the design schedule. Chose the proper tower and stringing plan willaccelerate the project, enhance the quality of project and reduce the cost. Thus, the study ofPower transmission tower and stringing project scheme is very important.Because of scheme of direct-current tower and stringing project involve lots of subject,including quantify index and qualitative index. This paper based om ManufacturingTechnology of Power Transmission Tower (GB/T2694-2003). State Grid Corporation ofPower Transmission and Transformation Engineering Construction TechnologyDemonstration Manual, State Grid Corporation and Transformation Project StandardizedOperation Manual and Ningdong-Shandong±660kV direct-current transmission projectcontact. Aiming at the character of the topography and iron tower. We use the scheme ofinside suspension and stringing around rod decompose the towers to construct the project ofNingDong-Shandong±660kV direct-current transmission Ji-1Part.The paper firstly introduce the background and the meaning of task, related currentsituation and study trends all over the world. Secondly, explain the660kV direct-currenttransmission tower and the principle of stringing technology. Thirdly, analyses thedirect-current transmission control measure, and stringing project technology in details. In theend, conclude the main study of the task and look forward to the future systematic. Theconsequence of the study support the direct-current power transmission project with valuableand scientific proper proof.
