Rekonstrukce ocelových příhradových stožárů elektrického vedení VN 180/94 v Třebovicích

Abstract

This thesis deals with the assessment of steel lattice towers of power lines voltage 22 kV, which is located in Ostrava - Třebovice and proposing measures for corrosion weakened elements. Loads on the structure was determined according to the standards for electrical overhead lines exceeding AC 45 kV. The individual elements were assessed at the ultimate limit state and usability. Load from wires caused by changing climatic factors were calculated using the equation gravity catenary and equations. The work also includes the calculation of mechanical tension wires and report limit states. In conclusion, is designed and assessed the reconstruction of the most fragile elements of corrosion and is recommended corrosion protection. Work also includes technical report and relevant technical drawings.
