Definitions

  • the present invention relates to a stationary induction device coil that achieves miniaturization by reducing its height.
  • Patent Document 1 JP 2010-28150 A (Patent Document 1).
  • This patent document 1 states that “a conductor is wound a plurality of times from the outer circumference in the coil radial direction toward the inner circumference to form a step, and then stepped up in the coil axial direction, from the inner circumference to the outer circumference in the coil radial direction.

  • the present invention has been made in order to solve the above-mentioned problem, and the conductor is wound in a spiral shape from the outer periphery in the coil radial direction to the inner periphery, and when it is wound up to the innermost periphery, it is stepped up from the inner periphery. Wind toward the outer circumference. These are stacked in the height direction. By repeating this, a coil is formed.
  • the coil is formed by combining the stages in which the number of windings per stage is reduced so that the tap drawing portion is always the outer peripheral turn of the coil.
  • the conductor can be drawn continuously without interrupting the winding work, so that a part of the tap lead-out portion is formed at the number of times of the tap lead-out portion so that a subsequent tap terminal can be easily connected.
  • the tap lead-out portions are alternately shifted inward and outward in the coil radial direction to secure an insulation distance not only in the coil axial direction but also in the coil radial direction.
  • the winding space can be made efficient, and the coil height can be reduced while ensuring the insulation distance between the taps.
  • the height of the stationary induction device coil can be reduced, and a smaller, lighter and more economical stationary induction device coil can be provided.

  • FIG. 1 shows a molded coil 10 as an example of a coil applied to this embodiment.
  • the winding start 3 of the conductor 1 was performed from the outer end of the coil, and a step was formed by winding a plurality of turns from the outer periphery to the inner periphery in the coil radial direction in the order of the numbers given to the conductor 1 in FIGS. After that, it goes up and then winds from the inner circumference to the outer circumference. By repeating this up to a specified number of turns, a coil shape is formed, and the resin layer 2 is formed.
  • the resin-molded coil of this example is a coil that is formed while forming a flat wire and bending it edgewise.
  • the flat wire is divided into a straight portion and a bent portion, and different forming methods are performed.
  • the rectangular wire 1 is passed between the rollers 5 and 5 installed at the top and bottom, and the angle of the roller 5 is changed by the wire forming portion 4.

  • the position which attaches this tap lead wire is arrange
  • FIG. 5 shows a coil wound with a conductor as in FIG.
  • the coil shown in FIG. 4 is different from the coil shown in FIG. 4 in that tap lead portions 6a 'to 6e' on the outermost periphery are alternately shifted inward and outward in the coil radial direction.
  • the distance d in the coil radial direction between the inner tap lead portion and the outer tap lead portion is at least the following, where E is the insulation distance of the tap lead portion and h is the axial distance of the coil in the adjacent tap lead wire: It is necessary to satisfy the formula (Equation 1). However, when a tap lead wire is connected to the tap lead portion, it is necessary to ensure an insulation distance between conductors including the tap lead wire.
  • the distance between the tap lead portions 6a ′ and the tap lead portion 6b ′ is sufficiently long from the tap lead portions 6b ′, so that the distance between the tap lead portions can be equal to or greater than the insulation distance. Further, a sufficient distance can be provided between the tap lead portion 6a ′ and the tap lead portion 6c ′. That is, each tap lead-out portion can secure an insulation distance between them, and thereby the tap lead-out portion can be extended by winding a conductor two fewer steps in the coil axial direction.
