Abstract

This bachelor thesis is focussed on the initial action plan related to the documentation plan for the reconstruction of a section of an electricity distribution system. The main aim is to create a complete document for the remodelling of part of the distribution system in the village known as Bordovice and to sum up the information in this bachelor thesis. This building was earmarked by its submitter and owner ČEZ Distribution a.s. to be rebuilt for some incompatible technical conditions. The aim of the thesis is based on projecting the remake of the current overground junctions VN 22kV using 3 x AlFe 6 35mm2 conductors, which will be exchanged for a new overhead cable VN22kV AXEKVCEz 3x70+50 mm2. Furthermore the transformer station is to be replaced by a new column one, which will be equipped with a 22/0,4kV 160kVA transformer and in addition there will be an upgrade of one distension overground low voltage (LV) system AlFe 4x70 mm2 to a new AES 4x120 mm2 cable on every side of the transformer distribution station. A remake of the connections for residential houses will be installed in this area. The project documentation will be compiled for regional administration by the civil engineering department in the first round and implemented by the power engineering plan documentation subsequently. I will be working on the scheme and description of the individual technological or administrative steps which are essential for compiling the project documentation. This plan incorporates the mechanical dimensions of each supporting spot, information about peak traction, wind and ice conditions, electrical dimensions of external system of HV (high voltage), LV, suggestions about safety overground, protection from excess voltage and regional planning. The main outcome of this internship and the compilation of my work is a glimpse into the problems concerned with project realisation in this line of work and most importantly the actual commencement of the build, which will enable flawless distribution of electricity to consumers.
