Regulation system for climatic test chambers
Burian, Jan ; Palíšek,, Libor (referee) ; Polsterová, Helena (advisor)
This paper contains 5 main parts. The first deals with the general description and properties of the climatic chambers, their individual parts and how these parts work. The second part deals with the chamber of Angelantoni CH 340. In detail is described how the chamber works and there is description of this chamber up to individual parts. The third part deals with the reconstruction project, the possibilities of reconstruction and the method that the chamber reconstructed. The fourth part describes the hardware that had to be selected and replaced and which parts of the chamber had to be modified. In the last part is a description of the program that controls the chamber after the reconstruction.
Point-on-Wave Controller PWC600 and its capability to protect the HV substation
Šikula, Jiří ; Melnyk, Oleksiy (referee) ; Polsterová, Helena (advisor)
Mechanical and electrical stresses reduce the life of all devices. The lifetime of some devices is affected by these stress factors more, others less. For high voltage products, it's not just a lifetime or a price, but a security that should be the first. This thesis deals with protection of elements of high voltage switchboards. Specifically, it is a PWC600 Point-on-Wave Controller that attempts to minimize stress when connecting or disconnecting loads or generators.
Optimization of projection activities in EPLAN ELECTRIC P8 software
Obšil, Martin ; Bastl, Jiří (referee) ; Polsterová, Helena (advisor)
The thesis deals with the optimization of project activities in the software EPLAN Electric P8. First part introduces electrotechnical software EPLAN, the basic functions, and explains the methodology of the work in the program environment. This is followed by an analysis of the state of the electrical documentation of the TAC 75 circular saw manufactured by Exactcut s. r. o., and the method of designing. The thesis is also focused on the individual problems that make barriers between the average and the high quality level of design and the ability to use the available features of the purchased software. Thereafter, individual optimization steps and partial methods of reaching aims are described. Part of the thesis is devoted to finding solutions for interconnection of two engineering branches, which are electric and fluid technologies and in the end are revealed expansion modules of software, which can be used to achieve a higher level of professional planning activity.
Measure the impact of wireless technologies on TEM
Prokop, Martin ; Čudek, Pavel (referee) ; Polsterová, Helena (advisor)
The purpose of this diploma thesis is to research and compare available wireless communication technologies (frequency, modulation type, transmission speed and consumption). Describe transmission electron microscopes theory and deduce the most sensitive microscope parts to high frequency distortion. Investigate effect of wireless technology on CE standards and come up with, perform and evaluate the influence measurement of chosen technologies on base parameters of transmission electron microscope.
Development of an automatic analyzer samples carbon and sulfur ACS 820
Jaroš, Tomáš ; Sloboda, Martin (referee) ; Polsterová, Helena (advisor)
The thesis deals wiring design of automated analyzer ACS 820 for carbon and sulfur. Describes individually all parts and their functionality. Evaluates applicable control components. Thesis discuss design of safety circuit, that will secure safe use of instrument. Part of the thesis is realisation of electrical design and completing the control box.
Usability of OEE in the Automotive manufacturing plant
Poledník, Tomáš ; Steiner, Patrik (referee) ; Polsterová, Helena (advisor)
This diploma thesis deals with the design and implementation of a comprehensive solution for the collection of production indicators in the commercial vehicle sector, called Automotive. The design is done by analyzing the state and identifying the bottlenecks of the OEE (Total Equipment Effectivenes). Further, the thesis describes the general theory of efficiency, availability and FPY (First Pass Yield). Realization and visualization of several production equipment variants for raw data collection from production lines in the manufacturing company IMI International CZ s.r.o. - a leading manufacturer of pneumatic components for the automotive and automation industry.
Transfer the IEC 61850 standard for communication protocol ModBus
Šikula, Jiří ; ABB, Oleksiy Melnyk, (referee) ; Polsterová, Helena (advisor)
This work describes the modbus communication protocol used in earlier and recent medium voltage switchgears. It also describes the IEC61850, a communication standard for most of the switchgear manufacturers as ABB, Siemens and others. It further describes the station automation gateway COM600, which is capable of conversion between many communication protocols. And finaly in this work you can find the concept of a device which is capable of conversion from IEC61850 to Modbus.
Determination of calibration deadlines devices
Henek, Tomáš ; Polsterová, Helena (referee) ; Jandová, Kristýna (advisor)
This work describes general function and structure of metrology, and defines methods for calibration interval determination. Further, it describes a Honeywell corporation’s calibration laboratory and gives specific recommendations for usage of method for calibration interval determination in the laboratory.
Modular control system wiring and small utility vehicles
Horníček, Evžen ; Špinka, Jiří (referee) ; Polsterová, Helena (advisor)
My thesis focuses on wiring of a small car ZEBRA. I study every single part of wiring and it´s connection. The aim is to describe current condition and set up update of wiring to reach more competitive status of this car in the market. Improvement prorosal is going to include group description of wiring, it´s assembling process and monitoring of working status of this car.
Comparison of electrical properties of alternative electro insulating fluids and mineral oils
Jurčák, Tomáš ; Polsterová, Helena (referee) ; Frk, Martin (advisor)
Master thesis deals with electrical insulating fluids in electrical engineering. It includes the distribution of liquids by ISO standard, distribution of oils and the current state of research into alternative electrical insulating liquids and description of selected dielectric properties. Furthermore, measurements were taken of selected electrical properties of the samples, and later their evaluation.
