Abstract

Układ regulacji napięcia trójfazowego transformatora podstawowego (1) pod obciążeniem składa się z transformatora regulacyjnego (2) i falownika AC/DC/AC (4). Uzwojenie wtórne transformatora regulacyjnego (2) jest włączone w szereg z uzwojeniem pierwotnym transformatora podstawowego (1). Uzwojenie pierwotne transformatora regulacyjnego (2) jest zasilane z falownika (4), który jest przyłączony do uzwojenia wtórnego transformatora podstawowego (1), bądź też falownik (4) jest przyłączony do uzwojenia wtórnego transformatora dodatkowego, którego uzwojenie pierwotne jest dołączone do uzwojenia wtórnego transformatora podstawowego (1). W transformatorze podstawowym (1) z uzwojeniem pierwotnym połączonym w trójkąt, uzwojenie wtórne transformatora regulacyjnego (2) jest włączone w obwód trójkąta uzwojenia pierwotnego transformatora podstawowego (1). W transformatorze podstawowym (1) z uzwojeniem pierwotnym połączonym w gwiazdę uzwojenie wtórne transformatora regulacyjnego (2) korzystnie jest połączone z uzwojeniem pierwotnym transformatora podstawowego (1) od strony gwiazdy, przy czym punkt połączenia uzwojeń w gwiazdę jest wykonany na uzwojeniu wtórnym transformatora regulacyjnego (2).The voltage regulation system of the three-phase basic transformer (1) under load consists of a regulating transformer (2) and an AC/DC/AC inverter (4). The secondary winding of the regulating transformer (2) is connected in series with the primary winding of the primary transformer (1). The primary winding of the regulating transformer (2) is powered by the inverter (4), which is connected to the secondary winding of the primary transformer (1), or the inverter (4) is connected to the secondary winding of the additional transformer, the primary winding of which is connected to the secondary winding of the transformer basic (1). In a basic transformer (1) with a delta-connected primary winding, the secondary winding of the regulating transformer (2) is connected to the delta circuit of the primary winding of the basic transformer (1). In a basic transformer (1) with a star-connected primary winding, the secondary winding of the regulating transformer (2) is preferably connected to the primary winding of the basic transformer (1) from the star side, with the star connection point of the windings being made on the secondary winding of the regulating transformer (2). ).
