Abstract

V diplomskem delu so obravnavani transformatorji za točkasto varjenje z enosmernim tokom. Predstavljena sta zgradba in delovanje varilnih transformatorjev za točkasto varjenje ter laboratorijski sistem za preizkušanje le-teh transformatorjev. Opisano je delovanje sistema, kjer so predstavljene težave in rešitve pri obratovanju laboratorijskega sistema. Namen tega diplomskega dela je določitev izgub varilnih transformatorjev z enosmernim tokom. Pri določitvi izgub v železnem jedru transformatorjev je predlagan nov način eksperimentalne ločitve izgub na histerezne in vrtinčne izgube. Prav tako je predstavljen način eksperimentalne ločitve izgub v kratkem stiku.

Secondary title:	Experimental determination of losses for spot welding transformers
Secondary abstract:	The diploma thesis describes resistance spot welding transformers, which perform the process of welding with DC current. This work presents a structure and working process of the resistance spot welding transformers, as well as the experimental setup for the practical tests. Difficulties that may occur during the working procedure of the laboratory experimental system and solutions to these problems are also one of the major topics described in the diploma. The purpose of the diploma thesis is determination of losses for resistance spot welding transformers, which perform the process of welding with DC current. The losses are determined from results, obtained with measurements. Measurements are carried out with open circuit tests and short circuit tests. The step forward is taken and the new method of how to divide the core losses into hysteresis and eddy current losses is developed. Separation of copper losses during a short circuit test is described as well.
