Abstract

PURPOSE:To prevent the variation of the tertiary voltage of a split type auto-transformer according to the tap position by a method wherein the main transformer having a first series winding, a shunt winding and the tertiary winding is accommodated in a first tank, a transformer having a first exciting winding and a tap winding, and a series transformer having a second exciting winding and a second series winding are accommodated in a second tank, the tertiary winding and the first exciting winding are connected in parallel, and the two series windings are connected in series. CONSTITUTION:Because a voltage to be applied between both the terminals (u), (v) of the shunt winding is the voltage on the middle voltage side, and is fixed, variation according to the tap position is not generated to excitation of a core. Accordingly the terminal voltage of the tertiary winding is also fixed regardless of the tap position. While the voltage on the high voltage side is made to be in the phase to be decided by adding the induced voltage of the series winding 11 of the series transformer 63 varying the induced voltage according to the tap position to the induced voltage of the seires winding 1 and the shunt winding 2 inducing a fixed voltage, and necessary voltage regulation is enabled by selecting the tap winding voltage, the turn ratio of the two windings 51, 11 of the series transformer. Construction of the main transformer side is simplified because the tap winding and the series transformer are not accommodated in the same tank, reliability is also enhanced, and at the same time, volume in the transportation limit can be enlarged as much.

Although it has the advantage that the winding IAh14 is relatively pure, the excitation of the iron core to change the voltage at the rope pressure Umeji terminal U by iJ is at the tap position by switching taps on the neutral point side. , so that the terminals a of the tertiary winding 3,

制限を越えることもありうる。For this reason, in order to keep a and b'411 constant, as shown in Figure 2, we have set up the resistor pressure regulator 61 during the description of the secondary circuit, and the tap is also energized from #113I4. However, a method has been proposed in which the change in the voltage of the main line 3 is compensated for by the change in the electric power of the curved voltage converter 61. However, this method is not suitable for system operation of the electric IE adjustment yoke of the pressurized road terminal.
When you want to make it bigger, the excitation rate of the iron core becomes larger, the transformer body becomes larger, and the ff
One company is also large, so there are restrictions on application.With an 11i winding Kogawa ware, the pressure at the end of the pressure Ii is adjusted.◆If the 8th round is set to 50 kv, the terminal voltage ratio is 80. (IV
, 63 becomes ■, 52LV. Therefore, if the excitation rate of the iron core is 11' and tJ for the joint face tap, it becomes 0.89P for the rated tap, and it becomes slightly less from LI to ()791' to LJ, which lowers the core excitation ( However, since the utilization rate is reduced, a thicker iron core must be used.In other words, the lachrymal pressure device itself may bleed and exceed the transport limit.

用例が少ない。As a well-known method to prevent the core from excitation and vibration, as shown in Figure 3, a tap winding-4 is wound around the main leg of the core.
From this, there is a method of exciting the series transformer 62 to indirectly change the high or medium voltage by 1 inch. However, this method has relatively few transportation restrictions, and although it is used in Iha, Voltage, and Otani equipment, transportation restrictions are severe for large container containers in the super-pressure class. Due to the strong desire of users not to incorporate a certain negative tap changer into the main body, there are few practical examples of such devices.

! At the same time, the valley electricity within the transportation limit can be increased accordingly. - Since the tap changer and the tap 45 wire are located in a separate tank from the main shock pressure regulator 1, even in the event of an accident with the car's tap changer, the impact of the accident on the main shock pressure regulator 1 can be reduced.
