Planning of low-voltage switchgear for systems with high security of supply

V pričujočem diplomskem delu je predstavljen postopek načrtovanja in izdelave nizkonapetostnih stikalnih blokov v objektih z visoko zanesljivim napajanjem. Uvodoma je prikazano napajanje objektov z visoko obratovalno zanesljivostjo, različne možnosti vključitve dodatnih napajalnih virov in glavne lastnosti, ki jih morajo pri tem zagotavljati nizkonapetostni stikalni bloki. V nadaljevanju so podane osnovne karakteristike nizkonapetostnih stikalnih blokov ter predstavljen opis postopka izbire primernih sestavnih delov in izdelave nizkonapetostnih stikalnih blokov. V zadnjem delu diplomskega dela pa se osredotočam na praktičen prikaz primera zasnove nizkonapetostnega stikalnega bloka v objektu z visoko zanesljivim napajanjem.This diploma thesis focuses on process of planning and constructing low voltage switchboards in high power reliability facilities. Paper begins with description of power supply to high power reliability facilities, different options of adding additional power supply and the main features that low voltage switchboards should provide. Further on basic characteristics of low voltage switchboards are provided. Paper describes the procedures for selection of proper components and manufacture of low voltage switchboards. The concluding part of the paper contains empirical demonstration of design example of low voltage switchboard in the facility with high reliability power supply
