Abstract

Ova specijalistička radnja opisuje princip i važnost obostranog napajanja pružnih uređaja što omogućava fleksibilnost i stabilnost sustava za napajanje. U slučaju neispravnosti NN mreže na jednoj strani, napajanje se uvijek može prebaciti iz izvora na drugoj strani, ako kojim slučajem ni taj izvor nije ispravan, napajanje se automatski prebacuje na pričuvne izvore napajanja (diesel agregat, baterije) čime se postiže besprekidno i sigurno napajanje.
Za napajanje pružnih uređaja izabran je PNK tipa PP41 4x25 mm2 koji udovoljava svim traženim kriterijima (padu napona i nazivnom opterećenju), a na Hrvatskim željeznicama se određuje prema tehničkoj specifikaciji ITS S2.012.

Abstract (english)

This thesis illustrates the principle and the importance of two-way power supply in railway devices, which provides flexible and stable power supply system. In case of irregularities of the local power network on the one side, the power supply can all times be transferred from the power source on the other side, and in the event of the latter malfunctioning, the power supply is automatically shifted to the emergency power system (diesel generator, batteries), resulting in uninteruptible and safe power supply. The cable chosen for the power supply of railways devices is PNK type PP41 4x 25mm2, which meets all established criteria (voltage drop and rated load), and on Croatian railways is determined according to the ITS S2.012. technical specification.
