れる。 In windings in which a plurality of plate-wound coil sections are stacked axially and connected in series, each adjacent coil section is generally connected on the same side, i.e., the inside and the inside, and the outside and the outside. A U-connected twin wire ring is constructed. However, although the connection between the coil sections is simple, the voltage of up to two coil sections is applied between the upper and lower coil sections, and the insulation dimensions are required to withstand that voltage, so the height of the winding is increased. It gets expensive. Therefore, for windings with high voltages, or where the winding height is particularly desired to be low, a so-called N-connected single wire loop is used to connect the inside of a coil section to the outside of an adjacent coil section, or vice versa. used. In the single wire ring, only the voltage of one section at most is applied between adjacent coil sections, so the insulation dimension between each coil section can be small, and the series capacitance of the windings is therefore large, reducing potential oscillations when shock voltage enters. It is often used because it has the advantage that it can be small.

に多くの絶縁寸法が必要となる欠点があつた。 On the other hand, in induction electric appliances such as transformers, the winding ratio is changed according to changes in the primary voltage to keep the secondary voltage constant. Divide into blocks and provide taps A ₁ to A ₃ , B ₁ to B ₃ , etc. at the ends of each block except for both ends of the winding that will become line ends U and X, and select the tap that corresponds to the change in the primary voltage. . In this case, for example, when minimum taps A ₃ and B ₃ are connected, if an impulse voltage enters from the line ends U and X, the free end of the winding
It is reflected at the A ₁ and B ₁ portions, and a large voltage is applied between the free ends A ₁ and B ₁ , that is, the opposing portions of the adjacent blocks.
Therefore, if there is a tap lead here, it becomes necessary to further increase the insulation dimension between both blocks, so the tap lead is not derived from the inter-block spacing 3, but from between the coil sections in each block as shown in FIG. Tatsupurid 21 was derived. FIG. 2 shows only one side of the longitudinal section of the winding, and the tap leads 21 are connected to the lead-out leads 22 to the line ends U and X.
is derived in the same direction as . By doing so, the arrangement with other windings, iron cores, etc. (not shown) is simplified with respect to the insulation means, and the overall size is reduced. However, in this case, coil sections AC1 and BC1 are formed by winding conductors at ends other than the line ends U and X of blocks 1 and 2 into plate shapes, and coil sections AC2 and BC2 adjacent to the coil sections AC2 and BC2, and the coil section
Voltages corresponding to a maximum of one coil section and two coil sections are applied between the end taps A ₁ and B ₁ of AC1 and BC1 and the leads 21, respectively. In other words, between the coil sections AC1 and AC2, BC1 and BC2, insulation dimensions that can withstand the voltage of up to three sections are required, and on top of that, the extension part of the tap lead 21 is difficult both in terms of size and electrode shape, so even more insulation is required. There was a drawback that insulation dimensions were required.

る必要があるから得策ではない。 It is an object of the present invention to provide a winding wire for an induction electric appliance that eliminates the above-mentioned drawbacks of the prior art and does not require extra insulation dimensions even in the tap lead portion. According to the configuration of the present invention, this purpose is to realize one series connection between the coil sections without leading out the tap in one block.
This is achieved by connecting the inner diameter side to the inner diameter side or the outer diameter side to the outer diameter side at a certain point. That is, the plate-shaped coil sections as a whole are made into a so-called N connection, and only one pair of them is made into a so-called U connection. By doing this, the direction of the crossover connection between the coil sections leading out the tapped lead wire is reversed,
The voltage conditions between the coil sections from which the tapped leads are led are eased. Although three or more odd pairs of U-connections may be provided, this is not a good idea since the insulation dimensions between the U-connected coil sections need to be larger than those of N-connections.

Further, the leads 21 of the taps A ₁ , A ₂ and B ₁ , B ₂ are led out from the respective coil sections to the side opposite to the block interval 3 . Furthermore, one adjacent coil section 33 in each block is connected in series at the same side connection portion 35. The series connection point is preferably located closer to the tap side than the center of the block so that the potential gradient is relaxed even if an impact voltage enters.

and BC2, only one section's worth of voltage is applied at most, which is half of the conventional voltage, and between adjacent sections AC1 and AC2 and BC1 and BC2, whereas conventionally three sections' worth of insulation is required, the theoretical In terms of insulation dimensions, the insulation size is the size of one coil section, and in practice, the insulation size is the size of two coil sections at most, resulting in a rational insulation configuration, and even considering the increase in the size of the 33 adjacent coil sections, it is compact and the purpose is to was able to reach.
