FIELD: technology for opening and closing current circuits. ^ SUBSTANCE: the switching device for reliable switching of current circuits contains two serial branches (1,2), where at least in one of the serial branches (1,2), in parallel to each other, at least two switching elements (11,12) are positioned, switching inputs (20) of which are connected to input point of serial branch (4,5), and switching outputs (21) of which are connected to input side of corresponding winding (8,9) of transformer (10), output sides of windings (8,9) are connected to one another and to output point of serial branch (6,7), where the windings of the transformer are made in such a way, that strengths (17,18) of magnetic field of both partial currents (15,16) of consumer current (14) in transformer (10) act in directions opposite to each other, and between the output points (6,7) of serial branches (1,2) the capacitor (13) is provided. ^ EFFECT: increased reliability of commutation. ^ 49 cl, 7 dwg |
