Abstract
Uređaj za određivanje broja navojaka transformatora je sačinjen od jednofaznog etalon transformatora (ET) i dva voltmetra (Vʹ1) i (V″1) za merenje napona (Uʹ1) i (U″1) na krajevima primara i sekundara navedenog transformatora, gde se njegov namotaj primara povezuje redno sa namotajem primara ili sekundara jednofaznog ili trofaznog ispitivanog transformatora (IT), a njihovi sekundarni namotaji ostave otvoreni. Voltmetrima (Vʹ2) i (V″2) povezanim paralelno sa namotajima primara i sekundara ispitivanog transformatora (IT) vrši se merenje napona (Uʹ2) i (U″2), a voltmetrom (Vʹ) povezanim paralelno sa namotajem grupe redno povezanih namotaja vrši se merenje ukupnog primarnog napona (U'). Brojevi navojaka primarnog i sekundarnog namotaja jednofaznog ispitivanog transformatora (IT), određuju se približno pomoću aproksimacione polinomne karakteristike funkcije broja navojaka u zavisnosti od srednje vrednosti ukupnog primarnog napona: (N2ʹ = f (UʹaSr) ) i (N″2 = f (UʹaSr) ). Dobijeni rezultati pokazuju da greška za oba namotaja iznosi približno 1 navojak, što opravdava primenu predloženog pronalaska za određivanje broja navojaka transformatora.The transformer thread counting device consists of a single-phase standard transformer (ET) and two voltmeters (V1) and (V1) for measuring the voltage (U1) and (U1) at the ends of the primary and secondary of said transformer, where its The primary winding connects regularly to the primary or secondary winding of a single-phase or three-phase test transformer (IT) and their secondary windings are left open. Voltmeters (V2) and (V2) connected in parallel with the primary and secondary windings of the transformer under test (IT) measure voltage (U2) and (U2), and a voltmeter (V2) connected in parallel with the coil of a series of regularly connected coils is the measurement of the total primary voltage (U '). The thread numbers of the primary and secondary windings of a single-phase tested transformer (IT) are determined approximately by the approximation polynomial characteristic of the function of the number of turns depending on the mean of the total primary voltage: (N2b = f (UaSr)) and (N ″ 2 = f (UaSr) ). The results obtained show that the error for both windings is approximately 1 thread, which justifies the application of the present invention to determine the number of transformer threads.
