Description
460 440 tycklig storlek och form vid olika tvärsnittsställen. Dessa urtagningar är nödvändiga för kylning och/eller lednings- dragning. 460 440 apparent size and shape at different cross-sectional places. These recesses are necessary for cooling and / or wiring.
Enligt ytterligare en utföringsform av uppfinningen är dimensionerna för skikten av bärarfolie något mindre än dimensionerna för angränsande plåtskikt. Därigenom förhindras vid pressningen och härdningen att ingen eller endast en ringa mängd plast tränger ut ur spalterna mellan de enskilda plåt- skikten, och därigenom kan man undvara ett reningssteg.According to a further embodiment of the invention, the dimensions of the layers of carrier foil are slightly smaller than the dimensions of adjacent sheet metal layers. This prevents during pressing and hardening that no or only a small amount of plastic penetrates out of the gaps between the individual sheet metal layers, and thereby a cleaning step can be dispensed with.
Uppfinningen beskrives närmare nedan under hänvisning till bifogade ritningar, på vilka såsom redan nämnts fig 1-4 visar varianter av läckflödesledande paket i transformatorer och induktansspolar, fig 5 visar skiktningen av de enskilda paketen och fig 6 visar fyra olika sätt att utföra skikt- ningen i olika riktningar. Pig 7 visar olika möjligheter att* bocka och förvrida de läckflödesledande paketen, fig 8 visar ett läckflödesledande paket uppbyggt av tvâ paketcchi.fig 9, , 11 och 12 visas paket, vid vilka de enskilda plåtskikten består av flera plåtar och skarvställena i de enskilda plåt- skikten är anordnade vid olika ställen. Slutligen visas i fig 13 och 14 ytterligare några varianter av pakettvärsnitt och tvärsnitt av kombinerade paket. t I fig 1-4 visas schematiskt en del av en transformator i sidovy och planvy. I alla fyra figurerna betecknar 1 trans- formatorkärlet, i vilken kärnan 2 befinner sig, vilken kärna är omgiven av en kompensationslindning 3. Kring denna är anord- nad en underspänningslindning 4, som i sin tur är omgiven av en överspänningslindning 5. Transformatorkärlet 1 med den i densamma befintliga transformatorn är på vanligt sätt fyllt med olja.The invention is described in more detail below with reference to the accompanying drawings, in which as already mentioned Figs. 1-4 show variants of leakage current conducting packets in transformers and inductors, Fig. 5 shows the layering of the individual packets and Fig. 6 shows four different ways of carrying out the layering in different directions. Fig. 7 shows different possibilities for bending and twisting the leakage-conducting packages, Fig. 8 shows a leak-flow-conducting package built up of two packagechi. Figs. 9,, 11 and 12 show packages in which the individual plate layers consist of several plates and the splice points in the individual plates. - the layers are arranged at different places. Finally, Figures 13 and 14 show some additional variants of package cross-sections and cross-sections of combined packages. Figs. 1-4 schematically show a part of a transformer in side view and plan view. In all four figures, 1 denotes the transformer vessel, in which the core 2 is located, which core is surrounded by a compensation winding 3. Around this is arranged an undervoltage winding 4, which in turn is surrounded by an overvoltage winding 5. The transformer vessel 1 with the transformer present in it is usually filled with oil.
I fig 1'är läckflödesledande paket 6 anordnade verti- kalt vid insidan av transformatorkärlet 1. Dessa paket 6 upp- visar listform och är anordnade vertikalt bredvid varandra med ett ringa avstånd i förhållande till varandra. I fig 1 visas tre paket 6 anordnade bredvid varandra.In Fig. 1, leakage flow conducting packages 6 are arranged vertically at the inside of the transformer vessel 1. These packages 6 have a strip shape and are arranged vertically next to each other with a small distance in relation to each other. Fig. 1 shows three packages 6 arranged next to each other.
Vid den läckflödesledande paketvarianten, som visas i fig 2, är förutom de vertikala läckflödesledande paketen 6 även anordnade korta, horisontella paket 7 vid de förstnämndas X2/ 460 440 övre ändar. Dessa paket 7 uppvisar samma bredd som paketen 6 och är även anordnade i linje med dessa.In the leakage flow-conducting package variant, which is shown in Fig. 2, in addition to the vertical leakage-conducting packages 6, short, horizontal packages 7 are also arranged at the upper ends of the former X2 / 460 440. These packages 7 have the same width as the packages 6 and are also arranged in line with them.
I fig 3 visas en anordning, vid vilken de listformiga läckflödesledande paketen 6 är anordnade horisontellt under varandra vid insidan av transformatorkärlet 1. Ett ytterligare listformigt låckflödesledande paket 7 är anordnat horisontellt vid den övre änden av lindningarna 3, 4, 5 i dessas längd- riktning.Fig. 3 shows a device in which the strip-shaped leak-flow-conducting packages 6 are arranged horizontally below each other at the inside of the transformer vessel 1. A further strip-shaped leak-flow-conducting package 7 is arranged horizontally at the upper end of the windings 3, 4, 5 in their longitudinal direction. .
I fig 4 är det läckflödesledande paketet 7 anordnat på samma sätt som i utföringsformen i fig 3. De vid transformator- kärlets 1 insida befintliga läckflödesledande paketen 6 är härvid anordnade vertikalt bredvid varandra.In Fig. 4, the leakage flow-conducting package 7 is arranged in the same way as in the embodiment in Fig. 3. The leakage-flow-conducting packages 6 located inside the transformer vessel 1 are in this case arranged vertically next to each other.
I fig 5 visas plåtar 8 med däremellan liggande plast- belagda folier 9. Till vänster i figuren visas den utförings- form, i vilken de plastbelagda bärarfolieskikten 9 är mindre än plåtskikten 8. Till höger visas den utföringsform, i vilken de plastbelagda bärarfolieskikten 9 är lika stora som plåt- skikten 8. Bärarfolien 9 kan vara utförd av glasväv, glassiden eller utgöras av ett polyetylentereftalatband, och bindemedlet kan utgöras av syntetisk kautschuk eller härdat epoxiharts- Tjockleken hos de här använda bärarfolierna 9 ligger mellan 0,025 mm och 0,5 mm. .Fig. 5 shows sheets 8 with plastic-coated foils 9 lying therebetween. To the left of the figure is shown the embodiment in which the plastic-coated carrier foil layers 9 are smaller than the sheet metal layers 8. To the right is shown the embodiment in which the plastic-coated carrier foil layers 9 are as large as the sheet layers 8. The carrier foil 9 may be made of glass fabric, the glass side or consist of a polyethylene terephthalate strip, and the adhesive may consist of synthetic rubber or cured epoxy resin. The thickness of the carrier foils 9 used here is between 0.025 mm and 0.5 mm. . .
Fig 6 visar fyra olika sätt att stapla de läckflödes- ledande paketen. Från vänster till höger visas ett horison- tellt, ett vertikalt, ett horisontellt förskjutet och ett vertikalt förskjutet staplat paket.Fig. 6 shows four different ways of stacking the leakage flow conducting packages. From left to right, a horizontal, a vertically, a horizontally offset and a vertically offset stacked package are displayed.
I fig 7 visas från vänster till höger ett rakt, ett enkelt bockat, ett dubbelt bockat, ett höjt och ett förvridet läckflödesledande paket.Fig. 7 shows from left to right a straight, a single bent, a double bent, a raised and a twisted leakage flow conducting package.
Fig 8 visar ett rektangulärt läckflödesledande paket , vilket är avrundat vid ena sidokanten. Med detta paket 10 är förbundet ett andra, mindre rektangulärt paket försett med en urtagning i ena hörnet.Fig. 8 shows a rectangular leakage flow conducting package, which is rounded at one side edge. Connected to this package 10 is a second, less rectangular package provided with a recess in one corner.
I fig 9, 10, 11 och 12 visas läckflödesledande paket, i vilka de enskilda plåtskiktcn 8 består av flera plåtar.Figures 9, 10, 11 and 12 show leakage flow conducting packages, in which the individual sheet metal layers 8 consist of several sheets.
Skarvarna 12 i de enskilda skikten 8 kunna, såsom visas i de fyra figurerna, ligga vid de mest olika ställen, varigenom en ökad styvhet hos paketen erhålles.The joints 12 in the individual layers 8 can, as shown in the four figures, lie at the most different places, whereby an increased rigidity of the packages is obtained.
