Description
Flercellet akkumulatorbatteri.Multi-cell accumulator battery.
Foreliggende oppfinnelse angår et flercellet akkumulatorbatteri særlig av bly-syretypen som delvis utmerker seg ved at de elektriske forbindelser er utformet med hensyn til strømtettheten i disse og derav forårsakede tap. The present invention relates to a multi-cell accumulator battery, particularly of the lead-acid type, which is partly distinguished by the fact that the electrical connections are designed with regard to the current density in them and the resulting losses.
Ved hittil kjente konstruksjoner har slike forbindelserConstructions known to date have such connections
som betegnes polbroer, langs hele sin lengde vært dimensjonert for den i et tverrsnitt opptredende strømtetthet. Forholdet er for en del betinget av at tilkobling av elektroder til polbroer skjer på which are called pole bridges, along their entire length have been dimensioned for the current density appearing in a cross section. The relationship is partly conditioned by the connection of electrodes to pole bridges on
«n konvensjonell måte, dvs. at polbroer som vanligvis har parallell-epipedisk eller tilnærmet parallallepipedisk tverrsnitt, med en av tverrsnittets lengdesider er i kontakt med alle elektroder med samme polaritet i en celle, hvorved elektrodene er anbrakt i avstand fra hverandre. Avstanden utfylles hovedsakelig av separatorer. "n conventional way, i.e. that pole bridges which usually have a parallelepipedic or approximately parallelepipedic cross-section, with one of the longitudinal sides of the cross-section in contact with all electrodes of the same polarity in a cell, whereby the electrodes are placed at a distance from each other. The distance is filled mainly by separators.
Ved oppfinnelsen oppnås en ikke uvesentlig materialbespa-relse sorn er av økonomisk betydning, samt mindre elektriske tap, hvilket er av teknisk betydning. Oppfinnelsen utmerker seg hovedsakelig ved metalliske innsatser i skilleveggene mellom de forskjellige celler, hvilke innsatser danner ledende forbindelses-organer mellom e1ektrodegrupper og enkeltvis er anordnet og utformet for i samvirke med tilsvarende åpning i en skillevegg å utove trykk på en i nevnte åpning anbrakt mengde av tetningsmasse (f.eks. epoxyharpiks) som fblgelig presses inn mellom innsatsen og åpningens mot innsatsen vendende vegger. The invention achieves a not insignificant material saving, which is of economic importance, as well as less electrical losses, which is of technical importance. The invention is distinguished mainly by metallic inserts in the partitions between the different cells, which inserts form conductive connection bodies between electrode groups and are individually arranged and designed to, in cooperation with a corresponding opening in a partition wall, exert pressure on a quantity of sealant placed in said opening (e.g. epoxy resin) which is usually pressed between the insert and the walls of the opening facing the insert.
Pol broene og dermed platesettene forbindes med hverandre etter et visst skjema alt etter som det. er sporsmål om serie- eller parallelIkoblinn. De hertil anvendte forbindelser anordnes vanligvis og som alminnelig kjent, utenpå batteri 1okkene, idet deler av pol-broene strekker seg innenfra cellene ut gjennom lokkene. Det har vært foreslått å forbinde polbroer i inntil hverandre liggende celler med hverandre uten at tiIkoblingsdeler derfor fores til utsiden av akku-mulatoren. Forslagene har som regel gått ul på å anordne forbindelser innenfor lokket og derved å fore disse gjennom skilleveggene mellom to inntil, hverandre beliggende celler. The pole bridges and thus the plate sets are connected to each other according to a certain scheme depending on the situation. is a trace measure of series or parallel Ikoblinn. The connections used for this purpose are usually arranged, and as is generally known, on the outside of the battery caps, with parts of the pole bridges extending from the inside of the cells out through the caps. It has been proposed to connect pole bridges in adjacent cells to each other without connecting parts therefore being routed to the outside of the accumulator. As a rule, the proposals have focused on arranging connections within the lid and thereby routing these through the partitions between two adjacent cells.
Derved oppstår tetningsprobleiner som hittil ikke har fått noen tilfredsstillende losning. Videre har det vært nddvendig ved ,fremstillingen av akkumulatorkar å ta hensyn til nevnte gjennom-føringer i skilleveggene, hvilket med hensyn til lagerhold og verk-tbys- eller fonnomkostninger ved fremstilling av karene, stiller seg ijokonomisk på grunn av de s torre omkostninger. This creates sealing problems that have not yet been satisfactorily resolved. Furthermore, it has been necessary in the manufacture of accumulator vessels to take into account the aforementioned penetrations in the partitions, which, with regard to stock and tool or material costs in the manufacture of the vessels, is uneconomic due to the large costs.
Ved hjelp av oppfinnelsen loses nevnte og andre problemer With the help of the invention, the mentioned and other problems are solved
på en enkel og rasjonell måte. En forde! som oppnås ved hjelp av oppfinnelsen, er at standard-akkumulatorkar kan anvendes og at spesielt f reins ti 1 iingsverkt by er overflbdig. En annen fordel er at strbmtapene er forholdsvis små. En ytterligere fordel er en ikke uvesentlig mate-rialbesparelse. in a simple and rational way. A forde! which is achieved with the help of the invention, is that standard accumulator vessels can be used and that, in particular, f reens ti 1 iingwerkt city is redundant. Another advantage is that the power losses are relatively small. A further advantage is a not insignificant material saving.
Oppfinnelsen skal forklares nærmere i det fblgende under henvisning til tegningene, som på fig. 1-6 viser en som eksempel valgt utfbrelsesform av oppfinnelsen, og hvor fig. 1 viser et snitt gjennom overdelen av to ved siden av hverandre liggende celler i en blyakkumulator med ifblge oppfinnelsen utfort forbindelse av to i forskjellige celler foreliggende platesett, fig. 2 viser samme for-bindelse «ett ovenfra og innfbyet i skilleveggen mellom to celler, fig. 3 viser bare forbindelsen og fig. 4 og 5 viser åpningen i nevnte skillevegg, hvori forbindelsen innfbyes tett. The invention will be explained in more detail below with reference to the drawings, which in fig. 1-6 show an embodiment of the invention chosen as an example, and where fig. 1 shows a section through the upper part of two adjacent cells in a lead accumulator with, according to the invention, a connection of two plate sets present in different cells, fig. 2 shows the same connection "one from above and embedded in the partition between two cells, fig. 3 shows only the connection and fig. 4 and 5 show the opening in the aforementioned partition, in which the connection is built tightly.
På fig. 1 betegner l ytterveggen i et akkumulatorkar somIn fig. 1 l denotes the outer wall of an accumulator vessel which
kan være utfort av hardgummi eller plast.can be made of hard rubber or plastic.
På samme figur betegner 2 et lokk som er forsynt med renner 3 som griper over karveggene 1 og 4, idet skilleveggene mellom cellene er betegnet med 4. In the same figure, 2 denotes a lid which is provided with channels 3 which grip over the vessel walls 1 and 4, the dividing walls between the cells being denoted by 4.
Elektroder 5 med mellom disse anordnede separatorer 6 er tilkoblet såkalte polbroer 7 som på sin side er tilkoblet eller i ett stykke med forbindelsen 8. Electrodes 5 with separators 6 arranged between them are connected to so-called pole bridges 7 which in turn are connected or in one piece with the connection 8.
For å kunne anbringe forbindelsen 3 i en mellomvegg 4 opptas i veggen et loddrett bunnhull 9 med tilstrekkelig stor diameter til at veggens 4 sideflater gjennombrytes, hvorved hulldybden er minst to ganger diameteren. Fra det nevnte hulls bunn fortsetter et bunnhull IO med mindre diameter enn det forstnevnte, et stykke lengere nedover i veggen. Hullets 10 diameter er mindre enn veggens 4 tykkelse. In order to be able to place the connection 3 in an intermediate wall 4, a vertical bottom hole 9 with a sufficiently large diameter is taken up in the wall so that the side surfaces of the wall 4 are penetrated, whereby the hole depth is at least twice the diameter. From the bottom of the aforementioned hole, a bottom hole IO with a smaller diameter than the former continues a little further down the wall. The diameter of the hole 10 is smaller than the thickness of the wall 4.
For forbindelsen li fbyes inn i veggen 4, anbringes i det nedre bunnhull 10 en viss mengde tetningsmiddel som er fortrinnsvis i halvflytende tilstand, så som epoxyharpiks eller en gummimasse. Som det fremgår av fig. 1 og 3 er forbindelsen 8 utfort med en slik form at den fyller ut hullet 9-10, idet den stbrre del 12 passer til hullet 9 og delen 13 passer til hullet lo. Delen 12 av forbindelsen 0 er dessuten forsynt med to renner 11 som sammen med hullets 9 sidevegger danner to lukkede kanaler som er i kommuniserende forbindelse med hullet 10 og munner ut ved veggens 4 overside. For the connection li fbyes into the wall 4, a certain amount of sealant is placed in the lower bottom hole 10 which is preferably in a semi-liquid state, such as epoxy resin or a rubber compound. As can be seen from fig. 1 and 3, the connection 8 is designed in such a way that it fills the hole 9-10, with the larger part 12 fitting the hole 9 and the part 13 fitting the hole 1. The part 12 of the connection 0 is also provided with two channels 11 which together with the side walls of the hole 9 form two closed channels which are in communicating connection with the hole 10 and open out at the upper side of the wall 4.
Ved innsetningen av forbindelsen 8 virker dennes del 13 som et stempel i hullet 10 og presser tetningsmidlet opp i rennene 11, hvorved der fåes en sikker tetning mellom forbindelsen og veggen. Det er en ytterligere fordel hvis tetningsmidlet er av den type som utvider seg under herdningen. When the connection 8 is inserted, its part 13 acts as a piston in the hole 10 and pushes the sealant up into the channels 11, whereby a secure seal is obtained between the connection and the wall. It is a further advantage if the sealant is of the type that expands during curing.
En pålitelig tetning fåes også om der anvendes et ikke tbr-kende på basis av latex fremstilt kitt. For oppfinnelsen i seg selv er valget av tetningsmiddel uten betydning. A reliable seal is also obtained if a non-abrasive latex-based putty is used. For the invention itself, the choice of sealant is irrelevant.
