Design of 22 kV Cable Network in the Existing Complex of Faculty Hospital
Blažek, Tomáš ; Procházka, Aleš (referee) ; Orságová, Jaroslava (advisor)
This thesis describes the reconstruction network 10 kV HV networks in a teaching hospital in the transition to a new 22 kV voltage level according to valid regulations. The paper describes the current state of technological equipment and its gradual replacement with new technology at 22 kV voltage level in each power units so as not to limit the operation of the hospital. For this purpose, the new backup system for rotating spare resources. The thesis deals with new input distribution, which will serve as a transfer point between the customer and distributor of electricity as well as advance the existing technological equipment.

Documentation for construction of new distribution transformer station and cables line HV a LV
Matouš, Milan ; Orságová, Jaroslava (referee) ; Bátora, Branislav (advisor)
The following master thesis is devoted to the design of distribution systems of LV (Low Voltage) and HV (High Voltage) voltage levels. The aim of the thesis is to create a complete project documentation for the construction of a new distribution transformer station (22kV/0.4kV) situated directly in the city of Blansko along with a transformer capable of performance of up to 630kVA. Subsequently a design of cable routes of LV and HV is included in the project documentation. The first part of the thesis introduces the fundamental issues and solutions regarding the design of electrical equipment related to the LV and HV voltage levels. Thereafter it deals with proper legislation, technical regulations and related standards. The second part is dealing with project documentation. More precisely analyzing each step in the process and thoroughly going through individual parts of the project documentation. Other focus of the thesis is software resources and tools which are essential for drawing documentation. Then follows a selection of appropriate electrical equipment and budget evaluation. The major portion of the work is a design of distribution transformer station and cable lines of LV and HV. Including dimensioning of the LV and HV switchboards, earthing system and fuse protection system. The essence of all this work serves as a foundation for complete design documentation.

Electrical installation in family house
Tesař, Jan ; Procházka, Petr (referee) ; Ondrejček, Vladimír (advisor)
This Bachelor Thesis is concerned with the design of the electrical installation of a family house. There are two main parts of the thesis – theoretical basis and the main design. In the theoretical part the reader is at first introduced to a powerline section, in which the electrical installation from the powergrid to a terminal equipment is described. Next part is about a low voltage wiring, where the commonly used types of wiring and devices are described. In the third part the reader can read about a lightning protection and its inner and outer parts. The main design consist of situational designs of devices and wiring in the house, switchboard designs, revision of the electrical protection and the technical report.

Milling machine CNC control
Krejčí, Jan ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This diploma thesis deals with rebuild of manual drill-mill machine BF20L into CNC mill machine, 3D model of that and eventual control using PLC. All axes are powered by stepper motors, with encoders, connected to control cards and industrial computer from company Beckhoff. For this control is made full switchboard, supplemented by electrical wiring diagram. Program control along with visualization is made in software TwinCAT 3. Drill-mill machine can be controlled manually or automatically by program.
