Návrh konstrukčního řešení automatického podavače tablarů pro skladovací systém SLL LogiMat / Design of automatic feeder of movable shelfs of storage system SSL LogiMatStoklásek, Tomáš January 2016 (has links)
The aim of this thesis is automatic movable shelves feeder design. the feeder is part of vertical lift storage system Logimat Total weight of movable shelf is 760 kg. The technical report contains feeder design calculation, feeder’s main parts strength calculation and the design of the way of picking the movable shelf from the storage lift. The report also contains feeder’s frame strength analysis using finite element method and sensor design for motion control.

Ochrany při zemních spojeních / Earth Faults ProtectionsOstruška, Jan January 2015 (has links)
The thesis deals with wattmetric and conductance principle of faulted feeder detection in medium voltage compensated distribution networks. These principles are analysed and tested with particular emphasis on high impedance earth faults. The first part of testing utilizes data about state of the system with earth fault, which was determined by designed static model of earth fault. The testing in the second part utilizes real records of high impedance earth faults. In both parts the wattmetric and conductance protections was presented on protective relays ABB REF 615, ABB REM 543 and Protection&Consulting RYo by means of unit OMICRON CMC 256plus. As a major result of performed tests are records of detection of particular earth faults. Based on these records it could be concluded, that functionality of protections is substantially dependent on magnitude of zero sequence voltage. Furthermore the wattmetric protections are dependent on fault resistance as well.
