More specifically, the present invention relates to a transformer winding having a relatively low voltage, high current, circular coil employing a wide sheet conductor, and an output conductor of this coil.

締付板9で締着されている。 Conventionally, there has been a transformer winding of this type as shown in FIG. A secondary coil 5 is concentrically arranged between a core-shaped insulating cylinder 2 and an insulating cylinder 3 arranged on the outer periphery of an iron core 1 with a stepped cross section, with a vertical duct piece 4 interposed therebetween. This secondary coil 5 is made by winding a wide sealed conductor 6 of approximately the same height as the outermost primary coil 11, which is a high-voltage winding, the required number of turns while inserting insulation between turns (not shown). , and is generally located inside the primary coil 11 . The vertical duct piece 4 provides cooling space for the coil and ensures mechanical support in the radial direction. 7a and 7b are an outer conductor and an inner conductor of the secondary coil 5. Iron core 1 and core-shaped insulating tube 2
A core vertical duct piece 8 is interposed therebetween to regulate the relative position of the two, and the iron core 1 is fastened by a clamping plate 9 via an intervening plate 10.

いことから、以上の問題が存していた。 In a conventional transformer winding having such a configuration, if the secondary coil 5 has a large current rating, the outlet conductor of the secondary coil 5 will have the same cross-sectional area as the wide sheet conductor 6. The output conductor 7a,
The dimension of 7b becomes large. Since the coil cross section is circular, it is difficult to increase the width dimension of the outlet conductor, and on the other hand, increasing the thickness dimension requires increasing the thickness of the vertical duct. . Furthermore, if the inner outlet conductor 7b is of a size that cannot be pulled out from the space between the vertical duct piece 4 and the core-shaped insulating tube 2 necessary for cooling the coil, the inner diameter of the secondary coil 5 must be increased. , it becomes uneconomical. Furthermore, if the outer conductor 7a is located further outward than the outer periphery of the secondary coil 5, the insulation dimension between the outer conductor 7a and the primary coil 11 will be small, which is unfavorable in terms of insulation performance, and in some cases. In the past, it was necessary to increase the inner diameter of the primary coil 11. This is because the lead-out conductors 7a and 7b have no choice but to arrange the lead-out spaces of the conductors in the radial direction of the winding when the wide sheet conductor 6 is used for the winding. There was a problem.

極少にし強固に巻回する必要等から、円形コイル
の場合には芯形絶縁筒2の省略は困難であつた。 As a means of expanding the radial space of the secondary coil 5, it may be possible to eliminate the core-shaped insulating cylinder 2, but this will prevent deformation of the secondary coil 5 due to handling after completion of coil winding and up to assembly, and prevent the deformation of the secondary coil 5, which may occur when the coil is short-circuited. In the case of a circular coil, it has been difficult to omit the core-shaped insulating tube 2 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.

寸法管理が困難であつた。 In addition, when starting the winding of a wide sheet-wound coil such as the secondary coil 5, the lead conductor is joined at the end of the wide sheet conductor, but the tension applied to the wide sheet conductor 6 during coil winding is Since the lead conductor 7b is large, it is necessary to fix the lead conductor 7b, and if the lead lead conductor 7b is insufficiently fixed, the wide sheet conductor 6 may become loose or the winding may be deformed.
Dimension control was difficult.

である。 This invention has been made in view of the above-mentioned circumstances, and has a structure in which the notch formed in the core-shaped insulating tube and the groove formed in the inner outlet conductor are engaged with each other. The purpose of this invention is to provide a transformer winding that eliminates the problems encountered in conventional transformer windings.
以下、この発明を、第2図、第3図に示す一実
施例について説明する。これらの図中で第1図と
同一または相当部分は同一符号で示し、説明を省
略する。 The present invention will be described below with reference to an embodiment shown in FIGS. 2 and 3. In these figures, the same or equivalent parts as in FIG. 1 are indicated by the same reference numerals, and the explanation will be omitted.

絶縁、15は適宜の詰物である。 In this embodiment, the inner outlet conductor 7'b to which the wide sheet conductor 6 is connected has grooves 17 formed along the longitudinal direction on both sides thereof, while the core-shaped insulating cylinder 2' has grooves 17 formed along the longitudinal direction. Form a cut parallel to the axis,
Both edges 2a of the notch are engaged with the groove 17. 12 is an insulating plate, 13 and 14 are insulating holes, and 15 is a suitable filling.
次に、以上の構成による作用効果について説明
する。 Next, the effects of the above configuration will be explained.

巻き作業が容易となる。(a) The core type insulating tube 2' and the inner outlet conductor 7'b are firmly connected, and are tightened by the tension of the wide sheet conductor 6 during coil winding. By appropriately selecting the material and strength of the conductor 7'b, and by using the filling 15, the position of the inner outlet conductor 7'b is restrained, so that the coil winding operation is facilitated.

うに、口出シ側の鉄心1の段数を減じることも
可能である。(b) In general, a wide sheet conductor 6, an outlet conductor 7'a,
Copper or aluminum, which has good conductivity, is used as the material for 7'b, but especially when aluminum is used, the dimensions of the outlet conductor become large and it becomes necessary to widen the vertical duct piece 4. In general, high current windings are often applied to low voltage specifications of 1000V class or less, and since there is sufficient insulation dimension margin, there is no need to thicken the vertical duct piece 4, and the coil dimensions can be reduced. Can be produced economically. If the dimensions of the inner outlet conductor 7'b are further increased, it is also possible to reduce the number of stages of the iron core 1 on the outlet side, as shown in FIG.

とが可能であり、コイルの変形を生じないので
コイルの取扱いが容易となる。(c) In general, power transformers are assembled from separately manufactured cores and coils, but the positional relationship between the core and coils is fixed by inserting a core vertical duct piece 8. Further, by inserting the insulating plate 12, the lead conductor 7'b is firmly fixed even after the assembly is completed.
Furthermore, when the coil is handled alone, the core-shaped insulating tube 2' is constantly under tension in the circumferential direction.
Since the lead conductor 7'b is made of a copper or aluminum plate, it can sufficiently withstand these tensions, and the coil does not deform, making it easy to handle the coil.

る。(d) As a measure to prevent the outside outlet conductor 7'a from popping out, the wide sheet conductor 6 can generally have a vertical duct piece 4 inserted between any turns in the coil. Although an example of the structure of a two-layer winding secondary coil has been shown, in order to eliminate local bulges in the outer diameter dimension of the secondary coil 5, a vertical duct is inserted into the inner layer near the outlet conductor 7'a. As for the piece, by using the adjusting duct piece 4a with a reduced thickness, an equivalent perfect circular outer diameter of the secondary coil 5 can be obtained, and it is possible to manufacture a small primary coil 11 while maintaining insulation dimensions. do.
