Generally, each unit transformer that constitutes a single-phase transformer
T 1 and T 2 have the structure of a normally manufactured single-phase transformer, and these two units are connected in parallel, so
The configuration of these windings, lead wires, etc. is as shown in FIG. 2 A and B. In this Figure 2 A and B, for simplicity, the winding is 1 of each unit transformer T 1 and T 2 .
Series windings 15A, 15B, 15C which are the next windings
And only 25A, 25B, and 25C are shown.
In each unit transformer T 1 , T 2 that uses a core with a five-leg configuration, the main legs 12A, 12C and 22A, 22 on both sides are
Series windings 15A, 15C and 25 wound around C
When the winding direction of A and 25C is clockwise as shown in FIG.
Series windings 15B and 25 wound around B and 22B
B, on the other hand, is formed by winding in a counterclockwise direction. In other words, the windings of each unit transformer T 1 and T 2 are configured to be the same when viewed from the primary terminal 5, and the series windings 15A, 15B, 15C and 25A, 25
The primary leads 16 and 26 from B and 25C are
As shown by the solid line, the adjacent winding wires are pulled out to one side along the circumferential surface and connected to the primary terminal 33, and the secondary lead wires 17 and 27 are similarly pulled out to the other side as shown by the broken line to connect to the secondary terminal. It is connected to 34.

In this way, when both unit transformers T 1 and T 2 have the same winding configuration, the primary and secondary lead wires 26 and 27 on the unit transformer T 1 side are connected to the tank 20 and the side leg 23A of the iron core 21, 23B, which not only makes routing difficult, but also causes insulation problems. In particular, the primary terminal 33
When 1000 KV and 500 KV are applied to the secondary terminal 34, the above-mentioned problem becomes even more pronounced, and there is a disadvantage that the amount of insulation applied to each lead wire 26, 27 must be significantly increased.

In order to eliminate this point, a single-phase transformer is constructed by each unit transformer T 1 and T 2 using each winding wire formed in the same winding direction as described above, as shown in Fig. 3 A and B,
Each primary lead wire 16 and 26, secondary lead wire 1
7, 27 may be pulled out to the same side as the primary and secondary terminals 33, 34, but in this case, the following problem arises. That is, the series winding 15 wound around the main legs 12A, 22A closest to the primary terminal 33
A, 25A, the series winding 15A wound around the main leg 12A ' on the unit transformer T1 side is connected to the outlet part of the series winding 15A connected to the primary lead wire 16 and the secondary lead wire. The outlet portions of the series windings 15A connected to the windings 17 are in an open state, and this space is one turn less than the prescribed number of winding turns, and there is no coil conductor. Therefore, in this space,
By winding and guiding one of the two primary lead wires 16 from the adjacent windings 12B and 12C, only one wire needs to protrude from the outer periphery of the series winding 12A. On the other hand, since the series winding 25A wound around the main leg 22A on the unit transformer T2 side does not have the above-mentioned open state portion, the primary lead wire 26 from the adjacent windings 22B and 22C Both of the wires protrude from the outer periphery of the series winding 25A, causing an insulation problem. 1
If an extremely high voltage such as 1 million V is applied to the secondary lead wire 26, this will become more noticeable, and the insulation distance between the primary lead wire 26 and the tank 20 may be increased, or the insulation applied to the primary lead wire 26 may be increased. A drawback arises in that the amount of material must be significantly increased. A similar problem occurs in the series winding 25C since two of the secondary lead wires 27 protrude.

1 drawn out from each winding of unit transformers T 1 and T 2
The three primary leads 16 and 17 connected to the secondary terminal 33 are derived directly from the windings 15A and 25A of the clockwise and counterclockwise turns closest to the primary terminal 33, but the remaining two windings 15B,
The primary lead wires 16 and 17 drawn out from 15C and 25B and 25C are connected to the adjacent winding 15A or 25A, or the two windings 15A and 15B or 2.
Guidance is provided along the outer circumferences of 5A and 25B. The secondary lead wires 17 and 27 are also led out along the outer periphery of the winding in the same way as the primary lead wire, although in opposite directions. When leading out the primary lead wires 16 and 17 as described above, as is already known, the number of turns in some coils of the winding is reduced in advance to create a space where no coil conductor exists. If the windings are formed in an open state and guided using this space, the width of each winding can be made equal, resulting in an extremely good insulation structure.

If a single-phase transformer is configured as in the present invention, simply reversing the winding direction of the winding of each unit transformer will result in a single phase transformer.
Because the secondary and secondary lead wires can be easily led out from the same side as the primary and secondary terminals, the amount of insulating material used can be significantly reduced, and each winding and lead wire has the same structure. This makes manufacturing easy and makes it possible to obtain an electrically stable single-phase transformer.

In the configuration, a primary terminal for connecting a primary lead wire from each winding is connected to one side near the longitudinal end of the tank between the unit transformers, and a secondary lead wire from each winding is connected to the other side. Connect 2
A secondary terminal is provided, and the winding direction of each winding of one unit transformer as seen from the primary or secondary terminal is configured to be opposite to the winding direction of each winding of the other unit transformer disposed facing each other. A single-phase transformer featuring: 2. The primary and secondary lead wires from the primary and secondary windings of each unit transformer are connected along the circumferential surface of the winding attached to the adjacent main landing gear.
The single-phase transformer according to claim 1, characterized in that the single-phase transformer is led out to the next terminal side. 3. The single-phase transformer according to claim 1, wherein each of the unit transformers is connected between the longitudinal ends of the tank by a connecting duct from which the primary and secondary lead wires are led out separately. transformer.
