Lattice Structures Improvement of Overhead Transmission Line Supports
Abstract: The article discusses the improvement of lattice structures of overhead transmission lines (overhead lines) by optimizing them and automating the design, including the creation of a computational model of overhead lines as a single system and an algorithm for its solution. It has been carried out the analysis of the stress-strain state and optimization of the structural forms of the trunk of the supports, taking into account the requirements of efficiency and manufacturability. A system of automated one-stage design of overhead line supports has been created. The article presents the design forms of new unified supports of increased reliability, developed taking into account the supporting influence of current-carrying wires and lightning protection cables, as well as the requirements of international standards, efficiency and manufacturability. In the study of anchor and corner supports by weight, possible operating modes were taken into account: normal, emergency and installation for different angles of rotation of the route. Based on the results of the research, rational applications of narrow-base tower-type supports were determined.
Keywords: overhead power line, optimal design, grid support, design model, automated calculation.
