Design of presentation electric switchboard for LV
Hlaváč, Jan ; Štefanov, Marek (referee) ; Bátora, Branislav (advisor)
This master’s thesis deals with the design of electric switchgear for low voltage, which will serve for presentation purposes. The switchgear is analogy of the modular system MNS 3.0, which includes the latest equipment of ABB Ltd. that is currently available on the market. Switchgears of this type are widely used in industry primarily for controlling motor units. For this reason, in the switchgear there are located motor starters in various performances, as well as distribution modules. In addition, the switchgear has an automatic transfer switch function in case of failure of one of the power supplies. The complete documentation of the switchgear is processed in the professional software EPLAN Electric P8 with use of the 3D software EPLAN Pro Panel for modelling device compartments. The final part of the thesis is the calculation of the maximum cable lengths that a potential customer can connect to the switchgear. In addition, an analysis of the power and control circuits was carried out for voltage drop calculations, as well as the effect of these voltage drops and capacitance of long control cables on the actuation of contactors.

Comparison of a cable duct filling in a reality and in a simulated situation with project softhe fullness of cable ducts in fact and in a simulation in the Pro Panel projection software
Cvaniga, Tomáš ; Poláček, Vladimír (referee) ; Polsterová, Helena (advisor)
This master’s thesis is focused on comparison of a cable duct filling in a reality and in a simulated situation with project software Pro Panel. The aim of this thesis is to differentiate simulated wiring harness and measured wiring harness. A theoretical part describes, what the distributor consists of, what is his basic function and where is it used. Some types of wires, which are used for Switchgear, are also mentioned. The history of program Eplan is mentioned shortly in next chapter as well as the documentation of corresponding project, which it will be constructed in future. A constructed project of low voltage compartment with software Pro Panel is also mentioned in practical part there will be. After construction of all devices, the whole project is checked with the software, whether it is correct or not. There were realized two types of measurements and simulations. It was necessary to find out, how to calibrate the simulation, to achieve similar simulation to measured simulation.
