SHORTING DEVICE DRIVE OPTIMALIZATION
Michalík, Marek ; ABB, Drahomír Tůma, (oponent) ; Dohnal, Petr (vedoucí práce)
Objective of this bachelor thesis is optimalisation of shorting device drive located in high voltage switchboard in cooperation with company ABB s.r.o, for which this work is being done. First part is about theoretical analysis of switching devices with focus on switching devices without arc. Mentioned shorting device also belongs to this group. Work continues with current information from the field of electric drives, which are later used in practical part. Thesis contains theory about direct current motors in greater detail, especially group of direct current motors with permanent magnets, because this type of motor is currently used to drive the shorting device . In final part it analyses whole drive and all of its parts, some paragraphs are dedicated to choosing type of optimalisation and evaluation of current drive solution with focus on its errors and problems. Nameplate parameters of current motor and gearboxes are described. In practical part there is protocol about test of shorting device, which took place in ABB s.r.o. In last part you can find results of unloaded drive measurement. Optimalisation options are carefully analysed and compared. All suggested solutions were discussed in detail with representatives and technicians from industrial companies.
