Definitions

  • the instant invention pertains to condensers wherein spools of elementary condensers are located between pairs of parallel conductors. It relates more particularly to an extremely compact condenser, that is one with a very high ratio kvalz/drn. capable of being used not only for low frequencies but also and mainly for very high frequencies, above a few kilohertz, where the effects of the superficial conduction of the current are noticeable.
  • condensers are constituted by a plurality of elemental spools stacked up to form piles.
  • the piles are placed within the condenser housing or tank with the axis of the spools normal to the refrigerating coil.
  • the cooling of condensers is not very advantageous because it is necessary to provide, between the inner wall of the tank and the part of the condenser under tension, solid electrical insulators which also act as thermal insulators.
  • An object of the present invention is therefore to provide a condenser which will eliminate the necessity of cooling by means of a refrigerating coil.
  • the invention is characterized in that the armature of the elemental spools are joined by parallel conductors constituted by metal strips folded in such a way as to provide at least one plate perpendicular in relation to the plate to which the armature of the elemental spools are joined.
  • the purpose in folding the metal strips, which constitute the conductors, is that larger strips can thus be used which, consequently, increases the conducting crosssection or, in the case of high frequency currents, the conducting surface.
  • the large metal surface also facilitates the thermal conductivity.
  • the folding of the metal strips at right angles also makes them lose their flexibility which results in sturdier mechanical assemblies.
  • the mechanical stability can further be enhanced, in accordance with the invention, by the fact that the assembly is rigidified by means of insulating plates provided with suitable slots through which part of the metal strips extend; said strips being then folded to retain the insulating plates.
  • each metal strip located in front of a cooling surface, that is, the surface of one wall of the tank.
  • FIGURE 1 is a perspective view of an assembly constituted by several elemental spools of condense-rs joined by means of folded metal strips.
  • FIGURE 1 gives a perspective view of an elemental condenser spool partly cut away to show the arrangement of the armature and dielectric layers.
  • FIGURE 2 is a cross-sectional view of the assembly of FIGURE 1,
  • FIGURE 3 shows a view, from underneath, of the assembly of FIGURE 1,
  • FIGURES 4, 5, 6 and 9 are cross-sectional views of other embodiments of the same invention.
  • FIGURES 7 and 8 are cross-sectional views of completed condensers.
  • FIGURE 1 two metal strips 1, 1', which form conductors, are folded in such a manner that, viewed in crosssection (FIGURE 2), they effect the form of two Ls.
  • One of the two plates of each metal strip 1 and 1 is "ice applied against the extremity of elemental spools of condenser 2 by means of tongues 15 whereas the other plate extends perpendicularly in relation to the first plate and longitudinally of the elementary spool.
  • FIG. 1 which shows an elemental spool 2
  • layers 20 and 21 are wound dielectric layers made, for example, of paper or polystyrene sheets.
  • a metallic armature for instance of aluminum sheeting, is wound between layers 20 and 21 and projects to the right.
  • the projecting part 13 of the armature is thereafter crushed to form a metallic contact surface 16 over which is secured, as by welding, a tongue 15 adapted to establish a contact with an outside conductor, such as one of the plates above referred to.
  • a second armature 19 also projects away from the dielectric layers 20 and 21 but on the left side and is also crushed to form a metallic contact surface 17 to which is secured a blade 15 to be fixed to an outside conductor.
  • This type of elemental spool is well known in the art.
  • the spools are joined to one of the plates of the conductors 1 or 1 by means of the tongues 15, 15 fixed to the two ends of each spool.
  • the assembly constituted by the conductors 1 and 1' and the elementary spools 2 is held together by means of an insulating board 3 which also constitutes the base of the pile and which is provided with two slots 7 and 7' (FIG. 3) having the shape of an L and through which the ends 8 and 8' of the metal strips extend. Ends 8 and 8' are folded over the insulating plate 3.
  • the stack of spools 2 is pressed between in sulating board 3 and another board 4 which is also provided with slots 6 and 6' having the shape of two Ls through which extend the ends of metal strips 1 and 1, cut out of metal bands 1 and 1'.
  • FIGS. 5 to 9 several piles of stacked spools may be grouped into a housing or tank 13 to form a condenser. It should be noted that the axes of the spools of all the piles, except those of FIG. 4, lie in a single plane so as to provide a substantial cooling surface and also that a minimum of conductor surface stands directly facing the inner wall of the tank.
  • Insulating boards 3 and 4 serve a dual purpose. Conductors 1 and 1' are secured to board 3 which acts as a base as aforesaid. Board 4 is used as a cover for the pile of spools, the height of which may vary slightly. This is why such fixing means as foldable fingers 5 and 5' is used which may be made at will and in accordance to the actual height of the pile.
  • the total height of conductors 1 and 1' must however be fixed because it is equal to the free height available within the tank 13 (FIGS. 7 and 8). All piles of spools must be well packed within the tank 13 and this is easily achieved since all the conductors 1 and 1 are of equal height. It is only necessary to place, under and over each pile built in accordance to FIGURE 1, one or several solid, but resilient electrical insulating layers.
  • boards 3 and 4 allow the spacing of the spools from the inner wall of the tank so that it becomes unnecessary to provide solid electrical insulators between conductors 1 and 1 and the inner wall of the tank, which insulators always act as thermal insulators as well.
  • the space available may be filled with an insulating fluid so as to avoid the use of a cooling coil.
  • the elemental spools 2 are located between two L-shaped conductors 10 and one T-shaped conductor 11; in FIGURE 6 spools 2 are placed between 3 two L-shaped conductors 1t) and one Sshaped conductor 12.
  • FIGURES 7 and 8 three assemblies built in accordance with the concepts of FIGURES 5 and 6 are shown in cross-section and in tank 113.
  • FIGURE 9 two stacks of spools are assembled by means of a T- shaped conductor 11 and a U-shaped conductor 14.
  • a condenser comprising: a plurality of elemental spools stacked one upon the other to form at least one pile; each spool having an armature contact surface at each end thereof; a conductor on each end of said pile of spools having a first plate joining adjacent contact surfaces; each conductor being further provided with at least one other plate extending perpendicularly of said first plate in parallel relationship with the axes of said spools.
  • a condenser comprising: elemental spools stacked one upon the other to form a plurality of piles of spools;
  • each spool having an armature contact surface at each end thereof; a conductor on the ends of each pile; each conductor having a first plate joining adjacent contact surfaces; each conductor being further provided with at least one other plate extending perpendicularly of said first plate and in parallel relationship with said plane.
  • a condenser comprising: elemental spools stacked one upon the other to form two piles of spools; the piles being disposed in alignment in such a way that the axes of the spools all lie in a common plane; each spool having an armature contact surface at each end thereof; a conductor on each of the outer ends of the piles and a common conductor for the intermediate ends; each conductor having a first plate joining adjacent contact surfaces; each conductor being also provided with at least one further plate extending perpendicularly of said first plate and in parallel relationship with said plane.
  • a condenser comprising: a housing; elemental spools stacked one upon the other to form a plurality of piles of spools; the piles being disposed within said housing in alignment in such a way that the axes of the spools all he in a common plane; each spool having an armature contact surface at each end thereof; a conductor on the ends of each pile; each conductor having a first plate joining adjacent contact surfaces; each conductor being also provided with at least one further plate extending perpendicularly of said first plate and in parallel relationship with said plane, said conductors being of equal length; an insulating base board fixed to said conductors and upon which said piles are set; an insulating cover board fixed to said conductors at the other end thereof and pressing said spools together; said boards being so dimensioned as to space said piles from the inner walls of said housing.
