The present invention relates to a three-phase voltage phase adjustment transformer that can perform voltage adjustment and phase adjustment independently. [0002] A conventional three-phase load voltage phase adjusting transformer is provided separately from a main transformer and the main transformer as shown in Japanese Patent Laid-Open No. 7-254520. And a phase adjuster. In such a configuration, the main transformer is provided with a primary winding, a voltage adjusting tap winding, a secondary winding, and a tertiary winding tertiary winding. An excitation winding for connection, a tap winding for phase adjustment, and a stable winding for triangular connection are provided. In addition, the triangular winding tertiary winding on the main transformer side and the star winding excitation winding on the phase adjuster side are connected in parallel. In the conventional three-phase load voltage phase adjustment transformer configured as described above, a separate phase adjuster is connected to the tertiary side of the main transformer. There is a drawback that the capacity that can be connected as a tertiary phase-adjusting equipment that becomes a load and becomes a tertiary external load of an actual main transformer is limited. [0005] In addition, an installation base area for the main transformer and the phase adjuster is required, which is one factor that increases the total cost of the substation. The present invention has been made in view of this, and the object of the present invention is that not only voltage adjustment but also phase adjustment is possible on the main transformer side, and a separate phase adjuster is not required. The purpose of the present invention is to provide a three-phase voltage phase adjustment transformer that can reduce the installation base area and reduce the total cost of the substation. The present invention adds a voltage adjusting tap winding provided on the main transformer side, and further provides two phase adjusting tap windings corresponding to one. Each phase adjustment tap winding of each other phase is electrically connected at a phase of 120 degrees by a phase adjustment two-phase load tap changer and a voltage of 90 degrees is generated for the phase. Is to achieve. DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the illustrated embodiments. FIG. 1 shows a schematic winding configuration of a three-phase voltage phase adjustment transformer according to the present invention, and FIG. 2 shows a primary winding configuration of the transformer. In the figure, the primary winding (V phase) includes a primary main winding 1, a voltage adjusting tap winding 2, and two phase (U phase, W phase) phase adjusting tap windings 4 other than the phase. 5 is provided. The two-phase phase adjustment tap windings 4 and 5 are connected by a phase adjustment two-phase load tap changer so as to have a phase of 120 degrees. As a result, a voltage having a phase of 90 degrees is obtained for the primary main winding 1. And the voltage adjusting tap winding 2 arranged on the neutral point side of the primary winding
Connected to. The voltage adjusting tap winding 2 of each phase is configured so that the primary winding is a star connection, and a voltage adjusting three-phase load tap changer 3 is attached to the neutral point portion thereof. In the three-phase load voltage phase adjusting transformer having the primary winding constructed as described above, the number of turns of the voltage adjusting tap winding 2 which is a part of the primary winding and the induction thereof. The direction of the voltage is adjusted by the voltage adjustment three-phase load tap changer 3 and the voltage ratio is adjusted by changing the turn ratio with the secondary winding. The tap switch 6 adjusts the number of turns of the phase adjusting tap windings 4 and 5 and the direction of the induced voltage, thereby adjusting the phase angle of the voltage induced on the primary side with respect to the voltage induced on the secondary side. can do. The three-phase load voltage phase adjustment transformer having the primary winding constructed as described above has been installed in the past as well as voltage adjustment and phase adjustment on the main transformer side. There is no need for a separate phase adjuster, there is no capacity limitation of the phase adjusting equipment that can be connected to the tertiary side, and the installation base area is reduced, so that the total cost of the substation can be reduced. According to the present invention described above, voltage adjustment and phase adjustment can be performed on the main transformer side, and a phase adjuster which has been conventionally installed can be dispensed with. This leads to a reduction in the total cost of the substation, which is effective for this type of transformer.
