Ślusarczyk, Patrik ; Wasserbauer, Vojtěch (referee) ; Ptáček, Michal (advisor)
This bachelor’s thesis deals with the analysis of the existing section of the 22 kV overhead line and the subsequent design of new supportin structure points, meeting the requirements of the operator and generally applicable standards. This section is located on premises of the Větřní transformer substation, with is operated by distribution company EG.D. The content of this work is focused mainly on components, that are used in the area of interest of this particular company. The theoretical part discusses the characteristics of sub-elements of distribution systems and subsequently the mechanical properties under the action of external influences, which have a fundamental role in the behavior of the entire system. A mathematical apparatus is introduced, which is then applied during the design and inspection of the given section. The practical part first deals with the critical evaluation and control calculations of the current state of the line, in relation to the planned reconstruction. Subsequently, the core part of the work is focused on the proposal for the reconstruction of the section of interest, including the relocation of overhead line towers. This step is implemented in the form of drawing documentation and control calculations of the newly designed states, supplemented by assembly tables. Together with these steps, the work is extended by the necessary documentation for grounding the support points, the material specification of all parts and the basic project documentation itself, which can serve as supporting material during reconstructions facing a similar problem.
