UNITED STATES PATENT OFFICE.-
ELIHU THOMSON, 0F SWAMPSCOTT, MASSACHUSETTS, ASSIGNOB. T0 GENERAL i ELECTRIC COMPANY, A CORPORATION 0F NEW YORK.
ELECTROSTATIC CONDENSER.
Application tiled November 13, 1920. Serial No. 423,963.
To all whom t may concern.'
Be it known that I, ELIHU THoMsoN, a citizen of the United States, residing at Swampscott, county of Essex, State of Massachusetts, have invented certain new and useful Im rovements in Electrostatic Condensers, o which the following is a specification.
This invention relates to electrostatic condensers and more articularly to that type of condenser whic comprises a lurality of closely compacted conducting eaves or sheets suitabl insulated from one another. It has been ound that condensers of this type, particularly when operated on power circuits, become overheated with the result that the insulation is injured. One object of my invention is to provide such a condenser with means whereby heat be conducted -'awa from its interior.
Anot er object of my invention is to provide means whereby a pluralityof condensers may be prevented from becoming over-heated by enclosing the same in tanks containing a cooling and insulating fluid and causing this uid to circulate through the tanks. may appear from the following description taken in connectionwith the accompanying drawings, wherein Fig. 1 is a top plan view partly in section, and Fig. 2 is a side elevation also partly in section of a condenser and its enclosing casing, constructed in accord'ance with my invention; Fig. 3 is a detail of the slightly modified construction, and Fig. 4 is a diagrammatic view of l'two condenser casings and connecting pipes to permit of the circulation therethrough of a cooling fluid.
Referring to Figs. 1 and 2, the casing 10 has located therein a condenser 11, spaced from the casing by perforated strips 12 of insulating material. The condenser 11 is formed of thin sheets of 'conducting material 13, such as metal foil between which is located insulating material such for example as suitably` prepared sheets of paper. The conducting sheets 13 constitute the active elements of the condenser and are connected to its terminals.
At intervals throughout the body of the condenser and interleaved with the sheets 13 are plates or sheets 14 of substantial thickness and formed of material which is a good conductor of heat, such as aluminum Other objects and advantagesl electrical connection with the condenser terminals and are therefor inactive as condenser elements. By insulating the plates 14 from the active elements of the' condenser, the danger of the destructive discharge from these plates is minimized. A suitable liquid for cooling the condenser is the usual non-sludging transformer oil which should, however, be particularly-free from moisture. While considerable freedom may` be allowed in the spacing of the plates 14 it is preferable that the sections of the condensers which lie between adjacent plates 14 be made relatively thin.
Fig. 4 shows two condenser tanks connected by tubing 17 to provide. means for circulating the cooling oil through the tanks. Means may also be provided whereby the oil itself may be cooled. Such a means may take the form of radiators exposed to the air or in contact with cooling water or some form of refrigerating machine may be employed if desired.
Having now described my invention, what I claim and desire to secure by Letters Patent of the United Staes is:
1. In a condenser, a series of electrically active sheets and a plurality of electrically inactive sheets of high heat conductin capacity interleaved with said active s eets and arranged to conduct the heat from the interior of the condenser.
2. In a condenser, a series of electrically active sheets and a plurality of electrically inactive sheets of material having high heat conductivity, interleaved with said active sheets, said inactive sheets extendingoutwardly from the body of said condenser.
3. In a condenser, a series of electrically active sheets and a plurality of heat conducting, electrically inactive sheets interleaved with said active sheets at frequent intervals and formed external to the body of said condenser with enlarged heat radiating surfaces. t a
4. In an electrostatic apparatus, a casing ada ted to contain an insulating liquid, a
con enser comprising a series of electrically active sheets located within said casn and of the condenser, and a sheet of comparaa series of inactive plates formed o matively high heat conducting capacity interlo terial having hi h heat conductivity, interleaved with the first mentioned sheets and leaved with sai sheets and extending outextending beyond the same. 5 Wardly from the body of said condenser. In Witness whereof, I have hereunto set 5. In a condenser, a series of sheets of my hand this tenth day of November, 1920. metal foil having comparatively 10W heat conducting capacity forming active elements ELIHU THOMSON.
