Production automation of transformer components based on industrial robot
Procházka, Petr ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
The bachelor´s thesis focuses on the automate process of primary transformer´s soldering. My work is to assess proceedings that guarantee that tolerances given by the controlling company shall be as accurate as possible. Final version of the product is modified in such a way to meet a size criterion as well as strength, anti-corrosion, space and price standards. The final version of the product is tested by the robot during the process. The main task is the verification of the size stability during the operation. One of the point of my bachelor´s thesis is to descripe a plan of automate workplace. The main reason for designing a plan of automate workplace is to help employees and facilitate from demanding work in the process of primary coil soldering.

Voltage transformer
Kovařík, Martin ; Huzlík, Rostislav (referee) ; Ondrůšek, Čestmír (advisor)
This bachelor´s thesis focuses on the elements of equivalent circuit parameters of voltage instrument transformer TJC 7-G from the portfolio of ABB. Main focus is placed on correct identification of the leakage reactance of primary and secondary winding, which are used for correct settlement of protections. The measurement is done by using methods of measurement of transformer without load and with short circuited secondary terminal. The values are measured for different frequency levels, in order to determine precisely all the parameters. The theoretical part describes the use of instrument transformers, theoretical creation of equivalent circuit and parameters which affects the accuracy class. The conclusion contains the evaluation of different methods for determining the elements of the equivalent circuit and with its final assembly.

Instrument voltage transformers of outdoor type
Velešík, Petr ; Bušov, Bohuslav (referee) ; Vaněk, Jaromír (advisor)
The function analysis of instrument voltage transformer with the aid of his equivalent diagram and his phasor diagrams is main part of my masters thesis. I solve the influence and errors of his equivalent diagram’s elements on this instrument voltage transformer. Than I talk about suitable magnetic materials using for instrument voltage transformers. There are 3D pictures which show lay-out of instrument voltage transformers’s windings and his magnetic circuit.

Workplace layout design
Hlavatý, Pavel ; Dostál, David (referee) ; Juřica, Pavel (advisor)
The topic of the thesis is the design of workplace layout to improve the handling between workplaces in ABB s. r.o. The theoretical part of the thesis defines the concepts of lean enterprise and workplace layout. The analytical part analyses the workplace layout together with the production process and ergonomic conditions in the workplace. Furthermore, the work activities at the individual workplaces are analysed. Based on the identified shortcomings in the analytical part, suitable and feasible solutions are proposed. In the conclusion of the thesis, the overall benefits and economic costs of the project are evaluated.
