Y.', A CORPORATION OF DELAWARE MULTIPLE OB BUILT-UP EEECTRICAL CONDENSER Application filed October 22, 1927, Serial No. 228,073, and in Great Britain October 22, 1926. Renewed.
June 25, 1881.
This invention relates to multiple or built up electrical condensers of the type consisting of a plurality or multiplicity of individual condenser units, for instance condenser units of the roll or spool type, mountedin a framework or upon a suitable support and appropriately connected up to suit the reuirements of the electrical circuit in which t ey are to be used.
In connection with multiple or built-up condensers of this type, various proposals have been made with a view to facilitating the effecting of repairs or replacements and in one instance it has been proposed to construct a rack consisting of a series of groups of. condenser units arranged and sup orted in position so that any one unit may e removed without disturbing the other units. It has also been proposed to construct a built-up condenser consisting of a plurality of unit condensers of the spool type assembled in sets each of which consists of a row of unit condensers suspended from a pair of parallel conducting members secured at their %:(18 to a pair of upright supporting mem- The object of the present invention is to provide an improved form of built-up conenser in which repairs and replacements may be carried out in a minimum of time and with a minimum amount of dismantling.
With this object in view the present invcntion consists in a multiple or built-up electrical condenser comprising a floor, layer or rack made up of a plurality of self-contained condenser structures each consisting of a plurality of condenser units appropriately connected together andto the terminals of the condenser structure, the self-contained structures bein connected together by transverse members ocated at or adjacent their ends and the arrangement being such that any one of such structures may be readily removed or re laced independently of the others.
he invention also consists in a multiple or built-up electrical condenser in which the individual condensers are assembled to form aplurality of parallel rows appropriately held in their desired relative positions by transverse members located at or adjacent the ends of the rows so that the removal or replacement of a defective row is facilitated. Further features of the invention will be hereinafter described and delimited in the appended claims.
Referring now to the accompanying draw- 1ngs which illustrate by Way of example two convenient modes of carrying the invention into efi'ect Figure 1 is a fragmentary view of one form of built-up or multiple condenser bank produced in acordance with the invention.
Figure 2 is an elevational view showing one of the self-contained condenser units or structures employed in the construction shown in Figure 1. c
Figure 3 is a plan view of the arrangement shown in Figure 2 showing the manner in whichth'e individual condensers are connected up electrically.
Figure 4 is a view illustrating another form of built-up or multiple condenser produced in accordance with the invention.
In carrying the invention into effect according to one convenient mode, a plurality of individual condensers which are preferably of the roll or spool ty e, are assembled to form a plurality of sel -contained structures which may be secured in position in a framework or mounted upon a suitable base or support so as to be capable of being readily removed therefrom when desired.
One convenient form of self-contained structure is illustrated in Figures 2 and 3 of the accompanying drawings and consists of a single row of individual condensers O mounted and held in position between a pair of parallel strip members 1, 2 which are pie 'erably of channel shape in cross section.
ore than one row may be provided to each structure, if desired. The individual condensers are held in their desired relative positions by providing the strip members with a series of holes or recesses corresponding in shape and dimensions with projections on, or the end formations of, the central supports or cores of the individual condensers. Preferably the said holes and the projections (indicated at 3) of the central supports or cores are of square formation so that the assembly with the terminals of the individual be mechanically connected or coupled together by suitable screw-threaded tie rods,-such as 4, extending between the strips.
The indivi ual condensers may be connected up electrically in any desired manner but it is preferred to connect the same inthe manner illustrated in Figure 3 in which opposite sides of the condensers aresultably connected, as by soldering, to a pair of bus bars 5 a'nd6 running parallel with the channel-shaped strip members. One of the bus bars leads to an insulated bus bar terminal 7 at one end of the structure and the other to a similar terminal 8 at the other. end of the structure. These bus bar terminals which are provided with suitable insulating bushes may conveniently be suspended in position from the upper of the two parallel strip members by suitable right-angled brackets 9 secured to the upper strip member 1 in any suitable manner as by sweating.
To form what is known as a multiple condenser a plurality of self-contained structures are electrically connected and detachably mounted in a framework or upon a suitable base or support so as to permit ready removal therefrom, when desired. A. frag mentary view of one form of a built-up or multiple condenser produced in accordance with the invention and consisting of a single floor, layer orrack is shown in Figure 1 and consists of a plurality of parallel rows of condenser structures having their lower supporting members or channel-shaped strips suitably secured as by bolts or screws at or adjacent their ends to a pair of transverse supporting members 10 which may constltute or form part of a framework or the like. In the arrangement illustrated the bus bar terminals 7 and 8 of each condenser structure are connected to those of their neighbors by a pair of transverse conductor elements 11 located one at each end of the condenser.
Other systems of connecting up the struc tures may be employed, if desired. For instance .if it is desired to connect the selfcontained structures in series, shorter conductor elements 11 may be employed, say of a length suiiicient to connect two adjacent 1 form of built-up condenser the terminal mem-' bus bar terminals, the said elements being disposed in alternate positions at opposite ends of the condenser, or, by employing conductor elements of a somewhat longer length, various arrangements of parallel-series grouping may be made up.
It will be observed that in this improved bers are disposed in such positions that alterations of connections or regrouping may be carried out with facility and that an improved form of built-up condenser is provided having electrical connections readilyplacements) independently of the others in the direction of its length with a minimum amount of dismantling.
Figure 4 shows another form of multiple or built-up condenser produced in accordance with the invention. In this form the condensers are arranged in a plurality of floors, layers,-racks or tiers in an open framework which may, for convenience, be suspended from the underneath side of a condenser tank lid. The framework consists of four uprights, posts or supports 12 provided with two sets of transverse supporting members 10 on which a series of self-contained condenser units or structures may be mounted in rows in a manner similar to that described above and illustrated in Figure 1 so that they can be readily removed when desired. The framework may be secured to the underneath side of a condenser lid, illustrated diagrammatically at 13, in any appropriate manner so that the assembled or built-up condenser may be easily placed in position in its tank either before or as soon as impregnation has been effected. Any convenient number of floors, layers or racks, may be employed and the various floors or self-contained structures may be connected up electrically in any desired manner according to the demands of the user or the purpose for which the condenser is intended.
In the manufacture of multiple condensers built up of condensers of the roll or spool type, it has been usual to impregnate the individual condensers with a suitable dielectric impregnating medium prior to assembling same into a structure or framework which, in order to increase the efiiciency of the condenser and to prevent overheating, is ultimately placed in a tank filled or nearly filled with oil of a suitable known character. This mode of producing multiple condensers necessitates in most cases exposing the individual condensers during assembly to the deleterious effects of the atmosphere for quite a considerable period of time after impregnation has been effected and before being installed in their operative positions in the oilfilled tank. The present invention in one of its phases aims at reducing this period of exposure to a minimum.
Accordingly instead of impregnating the individual condensers with a suitable dielectric impregnating medium prior to assembly, it is preferred that the impregnation should be carried out while the individual condensers are inan assembled condition. That is to say, the individual condensers are impregnated either by subjecting the selfcontained structures to the impregnation treatment prior to mounting same in a framework or upon a suitable support or by mounting such structures in their assembled or operative positions and subjecting the whole to the impregnation treatment.
It will be appreciated that a method of manufacturing built-up condensers in which the individual condensers are subjected to impregnation after they have been mounted in their assembled or operative positions possesses many advantages over one in which the individual condensers are impregnated be fore being assembled. In the first place the individual condensers are in a more convenient condition for handling (during assembly) before impregnation than after and, secondly the period during which the individual condensers are exposed to the delete rious effects of the atmosphere after impregnation is eitherreduced to a minimum or eliminated entirely. In this connection it should be observed that the improved method enables abuilt-up condenser to be manufactured so that the only time the in dividual condensers need come into contactwith the air after impregnation has been effected is the few seconds needed to transfer the built-up condenser from the impregnating apparatus to its position in the tank filled or partially filled with the requisite quantity of oil. Alternatively the improved method may, in certain circumstances, be carried out that the customary period of exposure to atmosphere is entirely eliminated; for instance, the assembled condenser may be mounted in its operative position in its tank and impregnation effected therein so that transfer of the condenser from one vessel to another is rendered unnecessary.
Any suitable method of effecting impregnation may be employed in carrying out the present invention but it is preferred to employ a method which involves subjection of the assembled condensers to a reduced pressure or a vacuum in order to extract all traces of air therefrom followed by treatment, as by immersion, with oil or other equivalent fluid or semi-fluid insulating material of a suitable character.
It will be appreciated that While the invention is particularly suitable for use in connection with methods or apparatus employing roll or spool type condensers, its
held of usefulness is not confined to condensers of that type and may, if desired, be applied to built-up condensers employing condenser units of other types such as for example those which comprise folded laminae of dielectric material, such as paper, and metal.
Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:
1. A built-up electrical condenser comprising a rack made up of a plurality of condenser banks, each bank comprising a plurality of condenser units connected together to form a unitary structure, each unit comprlsing a plurality of individual condensers, each of the banks being removable independently of the others, and means for connecting said condensers in circuit.
2. A built-up condenser comprisin a rack having a pluralitv of condenser ban rs, each bank comprising parallel rows of condensers and transverse members for maintaining said rows in spaced relation, each of thebanks being self-contained and removable independently of the others, and means for connecting said condensers in circuit.
3. A condenser bank comprising a plurality of condenser units connected together to form a unitary structure, each unit comprising a plurality of individual condensers maintained in fixed relation to form a unltary structure by parallel bars, transverse members for maintaining said parallel bars in spaced relation, and means for connecting said condensers in circuit relation.
In testimony whereof I aiiix my signature.
