<p>PURPOSE:To improve the dynamic stability and to increase the reliability of a device by constituting tap windings of the combinations of specific connections and connecting the combinations by anti-parallel bodies consisting of two pairs of thyristors. CONSTITUTION:A voltage/phase adjusting single winding transformer is constituted of a single winding main transformer 1 and a serial transformer 2, the single winding main transformer 1 consists of a serial winding 3, a shunt winding 5 and a low voltage winding 6 and the serial transformer 2 consists of an exciting winding 9, a stable winding 10 and a serial winding 13. In this case, an adjusting transformer 12 is added and thyristor groups are used in stead of tap switches. The serial winding 13 is connected to a node between the serial winding 3 and the shunt winding 5 and the adjusting transformer 12 is constituted of an adjusting winding 14 connected in parallel with the low voltage winding 6, voltage adjusting tap windings 15, 16 for a quadrature component and an in-phase component and their thyristor groups 17, 18 and connected as shown in a wiring diagram. Consequently, voltage and phase adjustment can be attained by thyristor control and rapid control and continuous switching can be attained.</p> |
