た。 In general, the internal structure of a transformer, which is said to be a split type, is as shown in Figure 1. Main legs 1 and 2 have main legs 1 and 2, side legs 5, and upper and lower yokes 7 and 8. A unit transformer 9 in which 1A and 2A are wound,
It is formed by a unit transformer 10 in which windings 3A and 4A are wound around the main legs 3 and 4 of an iron core having main legs 3 and 4, upper and lower yokes 7 and 8, and side legs 6, respectively.
The number of winding groups may be any number as long as it is two or more, and if there are restrictions on transportation of the transformer, the free ends of the upper and lower yokes 7 and 8 of each unit transformer 9 and 10 are connected. They were connected with pieces 7A and 8A interposed between them, separated from these parts during transportation, and reconnected at the site to form an integrated transformer.

ず）により貨車へ取り付けられる。 However, when considering transportation of a transformer having such a structure, there are various problems in realizing the above structure. First, transformers are often transported mainly by rail, and must be kept within certain transport limits. Figures 2A and 2B show cross-sectional views of typical structures during transportation. As is well known, when large capacity transformers are transported by rail, Schunabel type freight cars are used. A is a generally used method, in which the transformer contents 11 consisting of an iron core, windings, etc. are placed in a tank 12 which also serves as a lower tank.
It is stored within the transport limit 15 by covering it with the upper tank 13. The tank 12 is manufactured by attaching two upper and lower reinforcing beams 16 and 17 so that the suspension can withstand the strength of evacuation, internal pressure, etc.
It is attached to a freight car by a hinge (not shown) provided at its longitudinal end face.

配置することは不可能である。 In this case, the upper yoke 7 and the connection band 19 of the tank 12 and the upper tank 13 coincide on the horizontal plane of their extension. On the other hand, B is the lower tank 18
and an upper tank 20. In this case, the lower yoke 8 and the connecting band 21 coincide. On the other hand, in Schunabel freight cars,
The tank has a pin part for hanging the transformer and a crimp seat to prevent the freight car arm from tipping over in the longitudinal end surface of the tank, and it is impossible to place the connecting band part anywhere other than these upper and lower ends. .

式は、巨大な吊上設備とか空調設備などを要する
のみでなく、変圧器中身を気中に露出することに
なるので好ましくないなどの欠点がある。 Therefore, if a large-capacity transformer with the structure shown in Fig. 1 is to be manufactured, the unit transformers 9 and 10 must be stored in completely separate tanks during transportation, and then
At the site, it is necessary to store the contents of this transformer in a separate tank using a method such as pulling it into a separate tank, and then connect the upper and lower yoke parts to integrate them. Such a system not only requires huge lifting equipment and air conditioning equipment, but also has drawbacks such as undesirable exposure of the contents of the transformer to the atmosphere.
本発明の目的は二個の単位変圧器の分離、接続

である。 The large-capacity transformer of the present invention is a unit transformer comprising at least one main leg, an iron core consisting of an upper and lower yoke connected to the main leg at one end and a free end at the other end, and a winding disposed on the main leg. A unit transformer is formed by storing the contents in a tank consisting of at least an upper tank and a lower tank and having an opening formed in the side surface corresponding to the free end of the yoke, and these two unit transformers are connected to the above-mentioned unit transformer. The openings of the unit transformer are arranged so as to face each other, the free ends of the yoke of the unit transformer are magnetically coupled, and the openings of the unit transformer tank are connected by a connecting tank, so that the upper and lower yokes of the unit transformer are connected. It is formed by bending in the vertical and horizontal directions and facing the opening.

Bend it vertically in the same direction as the side legs 5 and 6, then return it horizontally avoiding the connecting bands 19 and 21, and bend it between the upper and lower yokes 7 and 8 in the vertical direction at the position where the winding is wound. two unit transformers 9, 10 at the position
Connecting yokes 22 and 23 are provided to connect the two. The connecting yokes 22 and 23 to be inserted may directly connect the two tanks 41 and 41 to provide a working space inside the tank, but as shown in the figure, the connecting yokes 22 and 23 are connected to the connecting yokes 22 and 23. It can also be formed to provide a. Further, in a single-phase transformer or the like, the space created between the upper and lower yokes 7 and 8 can be used to draw out and connect the high voltage lead 25. A pocket (not shown) may be made to protrude above or to the side of the connection tank 24 to house parts common to the two unit transformers, such as bushings or tap changers.

The upper and lower yokes 7 and 8 of the iron core are separated at their connecting yokes 22 and 23, suspended in the tank 12, and moved laterally toward the connecting tank 24 in FIG. 3 to be stored in the illustrated position. . If the transportation limit and the core size permit, the structure of the present invention can be achieved without the need for this connection portion to protrude to the side of the tank. The tank 41 has an opening 28 for accommodating the connecting yokes 22 and 23, and this opening 28 is connected to the opening cover 30 by a flange 29, thereby keeping the inside of the tank 41 airtight. The tank 41 is provided with upper and lower reinforcing beams 16 and 17.
It is connected to a vertical beam 31 provided on the longitudinal end face. The vertical beam 31 has a bolt hole 33 for attaching an adapter 32 for coupling with a Schunabel freight car.
If necessary, a horizontal beam 34 connecting the left and right vertical beams 31 may be provided separately. Further, an auxiliary beam may be attached to the opening cover 30 if necessary to connect the left and right vertical beams 31.

is provided, and a crimp seat 36 for attachment to a freight car is provided at the top. The adapter 32 is attached to the tank 41 with bolts 37, and the tank load is borne by the stepped portion 38. The beam portions that fix the left and right pin portions are connected by horizontal beams 39 and 40, and share a part of the bending moment of the tank generated at the opening 28 of the tank 41 with the horizontal beam 34. Therefore, the transformer tank is transported with sufficient strength, the adapter 32 is removed at the site, and the connection tank 24 is inserted between the unit transformers 9 and 10 as necessary to connect them.

る。 By configuring the large capacity transformer of this embodiment in this way, it is possible to perform separation and connection operations without exposing the contents of the transformer. While working,
Seal the openings with rubber membranes, etc., other than the penetration parts such as yoke parts, and use methods such as flowing dry air from the transformer side to prevent the transformer from being exposed to the air and create a sufficient working space for the joints. Iron connections can be made. Also,
Utilizing the space between the upper and lower yokes 7 and 8, the unit transformer 9,
Since it is possible to connect high voltage leads between 10 to 30 cm and tap leads, it is not necessary to provide a duct for connection. Additionally, a pocket can be made to protrude from the connection tank portion to accommodate a tap changer.
