Abstract
Napravljena je analiza rada induktivno opterećenog trofaznog neupravljivog mosnog spoja. Opisani su načini spajanja primara i sekundara ispravljačkih transformatora kao i satni broj transformatora. Teorijski je objašnjen utjecaj različitih parametara ispravljačkog transformatora na karakteristične valne oblike trofaznog neupravljivog mosnog spoja. Koristeći se didaktičko-multimedijalnom opremom Lucas Nülle se za pet različitih grupa spojeva transformatora došlo do novih shema spajanja eksperimentalnih pločica trofaznog transformatora i ispravljača. Izvršena su snimanja karakterističnih valnih oblika za ove spojeve pomoću virtualnog četverokanalnog osciloskopa. Za Yy0, Yy6 i Yy10 grupe spojeva provedena je harmonijska analiza struje izmjeničnih priključaka ispravljača koristeći virtualni harmonijski analizator. Zasnovano na rezultatima mjerenja, izvršena je usporedba valnih oblika te iznosa ukupne harmonijske distrozije, THDI, za različite grupe spojeva transformatora.
Abstract (english)
A theoretical analysis of an inductively loaded three-phase uncontrolled bridge rectifier is made. The ways of connecting the primary and secondary windings and the designating numeral of the rectifier transformer are described. The influence of different parameters of the rectifier transformer on the characteristic waveforms of a three-phase uncontrolled bridge rectifier is theoretically explained. Using the didactic-multimedia equipment from Lucas Nülle new circuit diagrams of the experimental three-phase transformer and rectifier circuit boards are developed for five different vector groups. The characteristic waveforms for these circuits are recorded using a virtual four-channel oscilloscope. For Yy0, Yy6 and Yy10 vector groups, a harmonic anaysis of the current was performed using a virtual spectrum analyzer. Based on the measurement results, a comparison of the waveforms and the total harmonic distortion, THDI, is performed for different vector groups of the transformer.
