System Connection of three-phase power transformers.

摘要

Connection system triafásicos power transformers.; The connection system of three-phase power transformers, electronically controlled, which prevents overcurrent connection occurring when fed to a three-phase transformer, is a composite set of multipolar conventional switch and three single-pole switches based solid state components (triacs) so as to give power to a three-phase transformer trigger pulses to the triacs are given sequentially first two of them at the right time and some time after the third. After a short time the conventional switch is closed and then stops given trigger pulses to the triacs.
