Realization Of Overhead Transmission Line CAD Based On ARX

Transmission line design plays an important role in power networkconstructing.To improve the work efficiency of Design work, the thesis introducesthe research and development of transmission line CAD system, chooses the mode ofAutoCAD's secondary development with the ARX and Visual C++.NET platform. Inthe process of developing this system, by studying on the theories and technologies suchas AutoCAD, Object ARX,C++, Database, COM, the author solved some key techniques,successfully developed out the integrated system such as the database managing andmaintenance ,the Querying and Drawing of Tower graph, mechanical calculation ofelectrical wire, the counting of hardwares. The system's success bring the traditionalhandicraft protraction, data's handling to automatically solved by computer, make theaccuracy, efficiency, benefits consumedly increase, and alleviates the work tension ofthe designers greatly.
