Complex Tests Carried out on the Basis of the Testing Ground for Power Transmission Poles and Tower Structures FSBEI HE «DONNACEA» (Part 2)
Abstract: Mechanical tests of experimental transmission line supports made according to individual projects are one of the mandatory conditions of Russian and international standards for their further use in the construction of energy facilities. Therefore, designers and manufacturers must have a testing base on which research and acceptance static and dynamic tests of transmission line supports and tower structures are carried out. The article describes an integrated approach to the testing of power grid structures carried out at the Testing Site of transmission line supports and tower structures of the DONNACEA. Complex tests of electric grid structures are provided by the presence of the test base of the Landfill, which consists of a universal test hall, a press room, a climate chamber and a wind tunnel. The testing base allows preliminary testing of hardware, individual elements, assemblies and fragments of supports; mechanical testing of wires; studies of icy loads; aerodynamic testing of structures and wires, etc. If necessary, three testing laboratories of DONNACEA accredited in the field of testing of building materials and engineering protection of buildings and structures in difficult geological conditions are involved in conducting special tests. The second part of the article describes the most interesting tests of various power transmission line supports and special tower structures: freestanding; portal and V-shaped on guy ropes; portal on reinforced concrete pillars installed in a natural base; mobile communication towers for static and dynamic loads; mobile communication towers based on reinforced concrete pillars and metal superstructure in a natural base. The described tests of the supports made it possible to identify errors made at the design, manufacturing stage, not taking into account the peculiarities of rolling and manufacturing of hardware.
