Definitions

  • the present invention relates to a coil on the magnetizable core of which at least one spacer element is arranged on at least two opposite sides, which spacer element serves to form a defined or uniform air channel between the magnetizable core.
  • a coil or a so-called winding material is used in various ways, such a use being used as a choke or in a transformer, for example.
  • the coil After being placed on the core, the coil must be fixed on the core using suitable wedges. This usually means that the winding and thus the entire coil structure is exposed to considerable mechanical forces and the winding can be warped or deformed as a result, so that there is no longer a uniform distance between the winding and the core. In addition, if the winding were warped or deformed, there would no longer be a uniform frictional connection between the winding and the core. This would then lead to acoustic emissions in the form of humming noises occurring during operation of the coil. But this is undesirable.
  • laminated cores As a core for coils. These laminated cores consist of a large number of sheets that are arranged one above the other. As a rule, a bobbin has at least one stack of a laminated core. Two laminated cores can be separated from each other using spacers. On the remote areas of the laminated cores, these are connected to a yoke, for example, in a later process step.
  • bandages are on the outside of the laminated core and can be designed as adhesive tapes. The stacks of laminations are then picked up between two bars. The strips can in turn be held together by means of bandages.
  • Spacer elements can be placed on the edges between the individual strips. An adhesive tape is then wrapped around these spacer elements so that a relatively strong bond is provided. This assembly can then be wound and placed on a yoke.
  • the strips which protrude beyond the laminated cores, have openings through which screws can be inserted.
  • the coil bodies can be firmly connected to a yoke using the screws.
  • the yoke has a corresponding opening through which the screws are guided.
  • bobbins have various disadvantages.
  • the laminated cores can slip during assembly and fastening.
  • a large number of individual components such as strips, adhesive tapes and spacer elements have to be used and aligned. Therefore, the cost of providing such a bobbin is increased.
  • a holder for choke coils is known, the holder surrounding a choke coil body with a coil arrangement and a pack of thin sheet metal discs.
  • the bracket includes a rim or clasp channel and a base plate for anchoring. When installed, the clasping channel encloses the choke coil body and is latched to the base plate.
  • the choke coil body is held firmly in position both by locking elements in the base plate and by locking elements in the clasping channel.
  • a coil arrangement which discloses magnetizable cores and windings surrounding the cores.
  • the cores are held by an insulation device which provides an air gap between the cores and the windings as well as an air gap to outer unwound cores.
  • the insulation device has two opposite shell parts, each having two half-shells for the cores. The shell parts are held together by side walls.
  • the object is to provide a coil in which the magnetizable core can be arranged in the coil during the winding and not only inserted afterwards and at the same time a defined, uniform air channel remains between the core and the winding.
  • the coil has at least one magnetizable core or at least one laminated core that forms the magnetizable core.
  • At least one spacer element is arranged on the at least one magnetizable core or the at least one laminated core on at least two opposite sides of the magnetizable core or the at least one laminated core.
  • the at least one spacer element is in contact with the at least one magnetizable core or the at least one laminated core at least at one point, with at least two spacers being arranged on the at least one spacer element, which extend along the at least one magnetizable core or the at least one laminated core.
  • one winding of the coil rests against the at least two spacers.
  • the winding consists of an electrical conductor, which preferably has a rectangular, square or round cross-section and is in contact with the at least two spacers with a force that can be preset. As a result, the spacer elements are pressed by the winding onto the at least one magnetizable core or the at least one laminated core.
  • the positions at which the spacers rest on the core or when using multiple cores, are located on the upper sides of the sheet metal and not on the sheet metal edges of at least one laminated core.
  • the stacks of laminations are pressed onto the laminations of a stack of laminations via the positions of the spacer elements when the winding takes place.
  • the metal sheets of the laminated core are thus held together and pressed against one another, since the spacer elements are arranged opposite one another.
  • laminations are used to form the core, they are arranged with the laminations abutting one another, with spacer plates made of electrically insulating material being able to be interposed between two laminations.
  • spacer plates made of electrically insulating material being able to be interposed between two laminations.
  • at least one pair of spacer elements is used for each laminated core, which presses the laminated core together.
  • insulating materials can be used as electrically insulating material.
  • plastic such as thermoplastics or duroplastics, or a ceramic material, or porcelain, or elastomers, or glass, or mica can be used to produce a spacer element.
  • Lamination stacks or cores can be spaced apart from one another via spacer plates, as previously described.
  • the laminated cores are also supported by the adjacent spacer elements with the spacers.
  • the spacer elements define the upper and lower limits of the winding, which encase the at least one core or the at least one laminated core at a distance from each other in sections.
  • the spacer elements can also be carriers of additional holding elements and/or delimiting clamps or spacer clamps.
  • the at least one core or the at least one laminated core is preferably located in the center of the winding.
  • the center of gravity of the core coincides with the center of gravity of the winding.
  • the core or cores or the laminated core or laminated cores is located in the center of the winding.
  • the at least one spacer element in conjunction with the at least one spacer is designed in such a way that it surrounds the core or cores or the laminated core or laminated cores in such a way that the core or cores or the laminated core or cores are centered when the winding is produced remain in the coil.
  • the respective spacer elements, the laminated cores/cores or the laminated core/core are fixed and held by the winding both in relation to the position of the spacer elements and to the position of the laminated cores/cores or the laminated core/core.
  • the spacer elements and the laminated cores/cores or the laminated core/core are fastened to one another or to one another, for example by suitable winding devices, bandaging, gluing or by means of heat input, with a regional fusion of the components (spacer elements, spacer plates, spacers made of plastic, for example) can occur.
  • the laminated cores/cores or the laminated core/core are then aligned to one another in a defined manner and can no longer slip.
  • the winding rests against the at least two spacers in a force-fitting and/or form-fitting manner.
  • the force with which the winding is guided around the laminated cores/cores or the laminated core/core is transmitted via the spacers to the spacer elements and these press on the laminated cores/cores or the laminated core/core.
  • the individual sheet metal plates of the laminated core or laminated cores are thus pressed together and held in position.
  • the at least one spacer element forms the shape of a semicircle.
  • This form-appropriate design ensures a uniform introduction of force via the spacer elements into the core/laminated core and, in addition, the semicircular shape is a shape that is simple and inexpensive to produce.
  • the at least one spacer element has a plurality of receptacles, via which the at least two spacers can be connected to the at least one spacer element in a positive and/or non-positive manner. This makes it possible, depending on the arrangement and number of recordings, to define the spacing of the winding around the core. Due to the positive and/or non-positive configuration, the spacers can be connected to the spacer element or elements and can be arranged on them.
  • the multiple receptacles on at least one spacer element are arranged equidistantly on the side of the at least one spacer element facing away from the at least one magnetizable core or the at least one laminated core.
  • the at least one spacer element and the at least two spacers consist of a non-electrically conductive material and/or a non-magnetizable material.
  • the winding of the coil presses the at least two spacers and the at least one spacer element onto the at least one magnetizable core or the at least one laminated core with the force with which the winding is guided to the coil and thus the at least one magnetizable core or the at least one laminated core is fixed in a non-positive manner between the at least two opposite sides of the magnetizable core or the at least one laminated core.
  • This ensures that the at least one magnetizable core or the at least one laminated core is fixed. This fixation almost completely avoids humming noises that can occur when the coil is in operation.
  • an air duct is present between the at least one spacer element with the at least two spacers and then adjacent winding and the at least one magnetizable core or the at least one laminated core.
  • the air duct is preferably used for cooling in that the waste heat within the coil can be dissipated to the outside through or via the air duct.
  • Particularly good cooling can be achieved by generating an air flow in the air duct.
  • a further defined air duct is created the sides of the at least one magnetizable core or of the at least one laminated core, on which no spacer element is arranged, is created, which is designed almost the same over the entire coil.
  • the at least one spacer element and/or the at least two spacers are rod-drawn or rod-pressed or made from glass-fibre-reinforced or carbon-fibre-reinforced plastic by means of a pressure resin injection process or a vacuum infusion process or a pultrusion process.
  • a pressure resin injection process or a vacuum infusion process or a pultrusion process the at least one spacer element and/or the at least two spacers are rod-drawn or rod-pressed or made from glass-fibre-reinforced or carbon-fibre-reinforced plastic by means of a pressure resin injection process or a vacuum infusion process or a pultrusion process.
  • the at least one spacer element has a semicircular basic shape and/or the at least two spacers essentially have a rectangular cross section or have the cross-sectional shape of an X.
  • the respectively opposite sides, preferably their middle surfaces, are concave. This shape gives the parts good mechanical strength and enables them to absorb high temperatures and forces.
  • the size of the air duct and/or the additional air duct is determined by the selection of the cross-sectional area or the diameter of the at least one spacer element, the shape of the at least one spacer element, the size and shape or the cross-sectional area of the at least two spacers and/or the type and position of the arrangement the at least two spacers can be adjusted on the at least one spacer element.
  • the size of the air duct and/or the further air duct can be selected and varied by these options.
  • the air duct can thus be adapted to the intended use of the coil, in particular for heat dissipation.
  • the spacer elements are arranged at the ends of the at least one laminated core, so that the ends of the spacer elements resting on the at least one laminated core are aligned with the the force generated by the winding, which arises during the winding process and can be variably adjusted during the winding process, can be introduced into the side edges of the at least one laminated core.
  • the force that is introduced during the winding is transmitted to the laminated cores and held by the spacer elements.
  • the coil is designed as a choke or for use in a transformer.
  • Cooling elements can then be inserted into these depressions which form between the larger and smaller metal sheets.
  • cooling with the use of supercooled nitrogen at a temperature of 66 K can be introduced directly into the air ducts, or lines are arranged around the core through which a cooling medium is routed past the core.
  • the electrical conductor is provided in the form of a preferably round wire and/or a strip with a rectangular or square cross-section and/or that the electrical conductor is coated with a primary insulation that the wrapping of Kerns takes place helically with the round electrical conductor and that an impregnation can then be carried out.

  • a spacer element is arranged on the laminated core in the area of its edges, at the upper edge of the uppermost sheet and the lower edge of the sheet, spaced apart from one another.
