支持を確保するためのものである。Conventionally, there has been a transformer winding of this type as shown in FIG. A left secondary coil is disposed concentrically between the core-shaped insulating cylinder and the insulating cylinder 3, which are arranged on the outer periphery of the iron core with a stepped cross-section, with a vertical duct bevel interposed therebetween. This secondary coil S is a wide sheet conductor 6 of approximately the same height as the outermost primary coil, which is a high voltage winding, and is wound with the required number of turns while inserting a winding insulation (not shown). and is generally located inside the primary coil //. The vertical duct beams provide cooling space for the coil and ensure mechanical support in the radial direction.

コイル／／との絶縁寸法が小となり。In a conventional transformer winding with such a configuration, if the seventh coil S has a large current rating, the cross-sectional area of the secondary coil S's output conductor should be the same as that of the wide sheet conductor B.PC
Nari 1 ro out conductor 7 a, ? The dimension b becomes large. Since the cross section of the coil is circular, it is difficult to increase the width dimension of the conductor.
Increasing the dimension in the thickness direction requires increasing the thickness of the vertical duct. In addition, the fact that the inner conductor 7b cannot be pulled out from the space between the vertical duct bead and the type 5 insulating tube λ necessary for cooling the coil means that the secondary coil S
It is necessary to increase the inner diameter of the tube, which is uneconomical. Furthermore, as the outer conductor 7a moves further outward than the outer periphery of the secondary coil 3-, the insulation dimension between the outer conductor 7a and the primary coil becomes smaller.

イルの場合には石彫絶縁筒ｄの省略は困難であった。As a means of expanding the radial space of the secondary coil S, it is possible to eliminate the stone-carved insulating tube, but after the coil winding is completed and until assembly, the deformation of the secondary coil S due to the link is prevented, which occurs when the coil is short-circuited. In the case of a circular coil, it has been difficult to omit the stone-carved insulating tube d because of the resistance to the radial electromagnetic mechanical force and the need to minimize the displacement of the wide sheet conductor 6 during coil winding and to ensure strong winding.

理が困難でル、つた。In addition, when starting the winding of a wide sheet-wound coil such as the secondary coil S, the rolled-out conductor is joined at the end of the wide sheet conductor, but at the same time as the coil winding, the wide sheet conductor A Since the tension is large, it is necessary to fix the outer conductor ?b, and if the outer conductor ?b is not fixed enough, the wide sheet conductor (,?) body l may become loose. However, the windings are easily deformed and dimensional control is difficult.

作できる。The material used for qL b is copper or aluminum, which has good conductivity. Particularly when aluminum is used, the dimensions of the conductor become large, making it necessary to widen the vertical duct bevel, but it is generally used for large currents. Winding wires are often applied to low voltage specifications of class 70007 or lower, and since there is sufficient insulation dimension margin, there is no need to thicken the vertical duct piece y, and the coil dimensions can be reduced, making it economical. Can be manufactured.

Output conductor q/b is firmly fixed. In addition, when the coil is handled alone, the island-shaped insulating tube 2' is always under tension in the circumferential direction, but since the conductor tlb is made of copper or aluminum plate, it can withstand these tensions sufficiently. This makes it possible to easily handle the coil since there is no trace of the coil.
