The motor drive control of the gas insulated disconnector of ABB switchgear
Kyseľ, Martin ; Ficek, Jan (referee) ; Orságová, Jaroslava (advisor)
This bachelor's thesis focuses on addressing the issue of controlling three-position disconnectors in gas-insulated switchgear by ABB. The aim of the thesis was to create drawings for three-position control methods and analyze their properties. The introduction provides a detailed analysis of the structure and components of gas-insulated switchgear. It further examines the issue of three-position disconnectors and their various control methods. The practical part of the thesis deals with the design of standardized control circuits for disconnector motor drives, which efficiently utilize space and optimize costs. The individual circuits were compared to select the most suitable replacement for the original control system. A model was created to verify the functionality of the proposed solutions, serving to demonstrate their operation.

The Partial Discharges Diagnostic in Gas-Insulated Switchgears
Ficek, Jan ; Hrnčíř, Bohumil (referee) ; Orságová, Jaroslava (advisor)
This work is focused on the measurement of partial discharges in gas insulated conductors manufactured by ABB. The theoretical part contains the definition of partial discharges, their analysis and detection methods. It also deals with the general description of gas-insulated substations and then with the concrete components manufactured at ABB in the Brno-Slatina production plant. The practical part describes the course of measurement, definition of the main problems and their explanation. The output from the practical part is a measurement library with given characteristics, which show the location and character of the problem in detecting partial discharge in a given encapsulated assembly.
