Opfindelsen angår et grundmodul til en flerpolet elektrisk stærkstrøms-motorafbryder af den i krav l's indledning angivne art samt en afbryder opbygget af sådanne grundmoduler.The invention relates to a basic module for a multi-pole electric high-current motor switch of the kind specified in the preamble of claim 1 and a switch constructed of such basic modules.
Der kendes allerede flere modulopbyggede afbrydere, f.eks. fra 5 de danske fremlæggelsesskrifter nr. 147.588, nr. 150.427 og nr. 165.470, EP 327.708, DE OS 3.729.616, EP 232.250, GB 2.185.632, GB 2.227.612, EP 112.232, EP 325.371, EP 228.723, og svensk fremlæggelsesskrift nr. 347.605. Der er dog ingen af de kendte afbrydere, som anvender trepolede moduler af den 10 art, som beskrives i det følgende.Several modular circuit breakers are already known, e.g. from 5 Danish publication no. 147,588, no. 150,427 and no. 165,470, EP 327,708, DE OS 3.729.616, EP 232.250, GB 2.185.632, GB 2.227.612, EP 112.232, EP 325.371, EP 228.723, and Swedish Petition No. 347,605. However, none of the known circuit breakers utilizing tri-pole modules of the kind described below.
Det er formålet med opfindelsen at tilvejebringe et grundmodul af den i indledningen til krav l angivne art, især til en tavleafbryder til montering på DIN-skinne eller direkte på et apparat. Afbryderen skal være af en høj kvalitet, kunne frem-15 stilles billigt og sælges til en konkurrencedygtig pris, idet afbryderen skal have en høj kortslutningsevne, være velegnet som sikkerhedsafbryder med en høj bryde- og isolationsevne, og det er især hensigten at fremstille et grundmodul, som er udformet således, at et og samme modul er egnet til at indgå i 20 afbrydere til flere forskellige strømstyrker og typer, som er lette at opbygge på stedet for tavlebyggeren, hvorved grundmodulet får så talrige anvendelsesmuligheder, at der er basis for at tilrettelægge en stærkt automatiseret produktion af afbryderen, hvilket er nødvendigt for at opnå en tilfredsstil-25 lende økonomi af produktionen. For også at minimere transportog lageromkostninger skal modulet være så kompakt som muligt, og gerne omtrent kasseformet, således at det er let at pakke og levere et stort antal grundmoduler i en kasse.It is an object of the invention to provide a basic module of the kind set forth in the preamble of claim 1, in particular for a switchboard for mounting on a DIN rail or directly on an apparatus. The switch must be of a high quality, can be manufactured cheaply and sold at a competitive price, the switch must have a high short-circuit capability, be suitable as a safety switch with a high breaking and insulation capability, and the purpose is to produce a basic module. which is designed so that one and the same module is suitable to be included in 20 switches for several different currents and types which are easy to build on the site of the board builder, thereby giving the basic module so many applications that there is a basis for planning a highly automated production of the switch, which is necessary to achieve a satisfactory economy of production. In order to also minimize transport and storage costs, the module must be as compact as possible, and preferably approximately box-shaped, so that it is easy to pack and deliver a large number of basic modules in a box.
Ved at indrette et grundmodul af den i indledningen nævnte 30 art, som angivet i krav l's kendetegnende del, opnår man, at den el-kyndige håndværker, tavlebygger eller elektriker, som har fået til opgave at udføre installationen, på stedet kan opbygge en passende afbryder ud fra en forsyning af grunddele, eller moduler.By installing a basic module of the kind mentioned in the preamble, as specified in the characterizing part of claim 1, it is achieved that the electrician skilled craftsman, panel builder or electrician who has been assigned the task of installation can build on the spot an appropriate disconnects from a supply of base parts, or modules.
DK 171005 B1 2DK 171005 B1 2
Grundmodulet ifølge opfindelsen udmærker sig især ved at være en lukket trefaset enhed, således at de vitale elektrisk ledende dele blandt selve de strøm-brydende og strøm-sluttende dele er helt utilgængelige. Det er derfor både let og fuldt 5 forsvarligt at samle en vilkårlig ønsket afbrydertype på stedet, og skulle det vise sig, at man på stedet har brug for en større strømstyrke end først antaget, er det en simpel sag at opbygge en større afbryder, hvori de oprindelig indsatte grundmoduler kan kombineres med yderligere afbrydermoduler.The basic module according to the invention is particularly distinguished by being a closed three-phase unit, so that the vital electrically conductive parts among the current-breaking and current-closing parts are completely inaccessible. It is therefore both easy and fully justifiable to assemble any desired circuit breaker type on site, and should it prove that on site a larger current than is previously assumed, it is a simple matter to build a larger circuit breaker in which the initially inserted base modules can be combined with additional switch modules.
10 Alle tre faser behandles i et og samme modul, og en eventuel udvidelse foretages således i alle tre faser på en gang, hvilket letter monteringen og gør det let at foretage ændringer.10 All three phases are processed in one and the same module, and any extension is thus made in all three phases at once, which facilitates mounting and makes changes easy.
Opfindelsen angår endvidere en flerpolet elektrisk motorafbryder af den art, der omfatter bevægelige kontakter, hvis bevæ-15 gelse styres af en trækstang, og hvor de bevægelige kontakter, styret af denne trækstang, er i stand til, for det første: at skubbes hen imod faste kontakter og danne bro mellem de faste kontakter for at slutte en strøm, og for det andet: at trækkes bort fra de faste kontakter for af bryde en strøm, og hvor 20 trækstangens bevægelse styres af en mekanismedel, og hvor afbryderen ifølge opfindelsen omfatter et antal grundmoduler ifølge et eller flere af kravene 1 til 4.The invention further relates to a multi-pole electric motor switch of the kind comprising movable contacts, the movement of which is controlled by a drawbar and in which the movable contacts, controlled by this drawbar, are capable, firstly: of being pushed towards fixed switches and bridges between the fixed contacts to terminate a current; and secondly: to be pulled away from the fixed contacts to interrupt a current, and the movement of the drawbar is controlled by a mechanism member and the switch of the invention comprises a the number of basic modules according to one or more of claims 1 to 4.
Opfindelsen skal i det følgende beskrives nærmere under henvisning til de ledsagende tegninger, hvor 25 fig. 1 viser et sprængbillede af et eksempel på en udførelses-form af en trepolet afbryder ifølge opfindelsen med to grundmoduler, fig. 2 samme med 4 grundmoduler, fig. 3 en skematisk oversigt over forskellige afbrydertyper, 30 fig. 4A et grundmodul, DK 171005 B1 3 fig. 4B et sprængbillede af samme, fig. 5 et sæt bevægelige kontakter, og fig. 6 et sprængbillede af en trækstang.The invention will now be described in more detail with reference to the accompanying drawings, in which: FIG. 1 shows an exploded view of an example of an embodiment of a three-pole switch according to the invention with two basic modules; FIG. 2 the same with 4 basic modules, fig. 3 is a schematic overview of different switch types; FIG. 4A a basic module, DK 171005 B1 3 fig. 4B is an exploded view of the same; FIG. 5 shows a set of movable contacts, and FIG. 6 is an exploded view of a drawbar.
5 Detaljeret beskrivelse af en foretrukken udførelsesform af opfindelsen:Detailed Description of a Preferred Embodiment of the Invention:
Fig. 1 viser et sprængbillede af en trefaset afbryder til 16/25 A med to grundmoduler 30. Nederst i fig. 1 ses en bunddel eller sokkel 12, med en bagside eller underside 13, der er 10 indrettet til at kunne klipses fast på en DIN-skinne. I begge sider af soklen indføres tre faste kontakter 14, der forbindes til hver sin terminal 16, til fastgørelse af de udefra kommende faseledninger, der skal tilsluttes den trepolede afbryder.FIG. 1 shows an exploded view of a three-phase switch for 16/25 A with two basic modules 30. At the bottom of FIG. 1, a bottom portion or base 12 is shown, with a back or underside 13 arranged 10 to be clipped to a DIN rail. On both sides of the socket, three fixed contacts 14, which are connected to each of their terminals 16, are inserted to secure the external phase wires to be connected to the three-pole switch.
En mekanismedel 25 skal indsættes i midten af sokkelen 12, og 15 på hver side af mekanismedelen 25 indsættes et grundmodul 30.A mechanism member 25 must be inserted in the center of the base 12 and 15 on each side of the mechanism member 25 a basic module 30 is inserted.
En stang 32 er indrettet til at passere gennem åbninger 33 i begge grundmoduler og tværs gennem mekanismedelen 25.A rod 32 is arranged to pass through openings 33 in both basic modules and across through the mechanism portion 25.
Mekanismedelen 25 består af en slæde 18, et sæt skinner 20, som bærer og styrer slæden, og to delvis cylindriske dele 22, 20 24. De nævnte dele er omgivet af et hus eller en kappe 26. Delen 24 er i den ene ende på kendt måde indrettet til at optage en ikke vist, firkantet håndtagsaksel, og er i den anden ende indrettet til at optage og gå i indgreb med delen 22, således at en drejning af håndtaget medfører en drejning 25 af delene 24 og - eksempelvis via en medbringer 23 på delen 22 - en forskydning af slæden 18.The mechanism member 25 consists of a carriage 18, a set of rails 20 which carry and guide the carriage, and two partially cylindrical portions 22, 20 24. Said parts are surrounded by a housing or sheath 26. The portion 24 is at one end of the carriage. known means adapted to receive a square handle not shown, and is at the other end adapted to receive and engage the part 22, so that a rotation of the handle causes a rotation 25 of the parts 24 and - for example via a carrier 23 on the part 22 - a displacement of the carriage 18.
I den viste udførelsesform er stangen 32 monteret i udskæringer 132 i slæden 18. Dermed vil en forskydning af slæden 18 langs skinnerne 20 bevirke en forskydning af stangen 32 og af 30 trækstængerne 103 i de monterede moduler 30, og dermed af bevægelige kontakter 123, 124, 125 inde i grundmodulerne 30.In the illustrated embodiment, the rod 32 is mounted in carvings 132 in the carriage 18. Thus, a displacement of the carriage 18 along the rails 20 causes a displacement of the rod 32 and of the 30 pull rods 103 in the mounted modules 30, and thus of movable contacts 123, 124. , 125 inside the base modules 30.

Disse kontakter er vist på fig. 4 og 5, der viser opbygningen af et grundmodul 30.These contacts are shown in FIG. 4 and 5 showing the structure of a basic module 30.
I fig. 1 ses over grundmodulerne 30 tre faste kontaktskinner 34 - 38, indrettet til at forbinde de to grundmoduler. Den 5 midterste kontaktskinne 36 er vist med en cirkelbueformet midterdel, der skal give plads til mekanismedelens cylinderformede dele 22, 24, der skaber forbindelse til et håndtag.In FIG. 1, three fixed contact rails 34 - 38 are arranged over the base modules 30, arranged to connect the two basic modules. The middle contact rail 36 is shown with a circular arcuate center portion to allow for the cylindrical portions 22, 24 of the mechanism member to connect to a handle.
De tre skinner trykkes ned i de dertil indrettede slidser 40 -44 i grundmodulerne. Det hele dækkes til slut af med en over-10 part 46, som spændes fast med skruer 48, vist nederst på tegningen. Derefter kan afbryderen klipses fast på en DIN-skinne.The three rails are pressed into the slots 40 -44 in the basic modules. The whole is finally covered with an upper part 46 which is fastened with screws 48, shown at the bottom of the drawing. Then the switch can be clipped onto a DIN rail.
Fig. 2 viser en tilsvarende afbryder til 40/63 A med fire grundmoduler. Alle de indgående dele er identiske med undtagelse af sokkelen 212, der kan rumme 4 moduler, og den tilsva-15 rende overpart 246, samt de strømskinner, 214 og 234-238, der danner de faste kontakter.FIG. 2 shows a corresponding switch for 40/63 A with four basic modules. All the incoming parts are identical except for the socket 212 which can accommodate 4 modules and the corresponding upper part 246, as well as the current rails, 214 and 234-238 which form the fixed contacts.
Fig. 3 skitserer forskellige afbrydertyper, som kan opbygges af det samme grundmodul 30.FIG. 3 outlines different switch types which can be constructed by the same basic module 30.
En "QA 16", dvs. en afbryder til 16 Amp, eventuelt med eller 20 uden nul-pol kan opbygges af et håndtag 320, et frontmodul eller overpart 346, et grundmodul 330 og en sokkeldel 312 med mekanismedel 325.A "QA 16", ie a 16 Amp circuit breaker, optionally with or 20 without a zero pole, may be constructed by a handle 320, a front module or upper portion 346, a base module 330, and a socket portion 312 with mechanism means 325.
En "QA 25/32", dvs. en afbryder til 32 Amp kan opbygges af et håndtag 320, et frontmodul eller overpart 346 med indlagte 25 strømskinner 334, der anes på undersiden af en plade 345, to grundmoduler 330 og en sokkeldel 312 med mekanismedel.A "QA 25/32", ie a 32 Amp circuit breaker may be constructed by a handle 320, a front module or upper portion 346 with inlaid 25 bus rails 334, which is seen on the underside of a plate 345, two basic modules 330 and a socket member 312 with mechanism means.
En "QA 63", dvs. en afbryder til 63 Amp kan opbygges af et håndtag 320, et frontmodul eller overpart 346 med indlagte strømskinner 334, fire grundmoduler 330 og en sokkeldel 312 30 med mekanismedel.A "QA 63", i.e. a 63 Amp circuit breaker can be constructed by a handle 320, a front module or upper portion 346 with inset power rails 334, four basic modules 330 and a socket portion 312 30 with mechanism means.

En "QSA 25/32", dvs. en afbryder til 32 Amp og med sikringer, som monteres på oversiden i en alternativ overpart eller frontmodul 355 eller 356, kan opbygges af et håndtag 320, det alternative sikringsbærende frontmodul 355, 356, fire grundmo-5 duler 330, og en sokkeldel 312 med en mekanismedel.A "QSA 25/32", ie a 32 Amp circuit breaker and with fuses mounted on the upper side of an alternate upper or front module 355 or 356 may be constructed by a handle 320, the alternative fuse carrying front module 355, 356, four basic modules 330, and a socket portion 312 with a mechanism agent.
En QP 80/100 med parallel-koblede brydemoduler kan opbygges, hvor man har brug for at slutte og bryde strømstyrke på op til 80/100 Amp. Frontmodulet er i denne udgave, på samme måde som sokkelen 312, indrettet med terminaler til montering af de 10 ledninger, der skal tilsluttes afbryderen.A QP 80/100 with parallel-coupled switching modules can be built where you need to connect and break current of up to 80/100 Amp. In this version, the front module, in the same way as the socket 312, is equipped with terminals for mounting the 10 wires to be connected to the switch.
Af fig. 3 ses endvidere, at sokkeldelen 12 eller 212 med fordel kan være indrettet således, at den kan monteres på DIN-skinne i to på hinanden vinkelrette retninger. Afbryderen vil kunne udvides med en fjerde og eventuelt femte pol med eller 15 uden brydefunktion.In FIG. 3, it is further seen that the base part 12 or 212 can advantageously be arranged so that it can be mounted on DIN rail in two mutually perpendicular directions. The switch can be extended by a fourth and possibly fifth pole with or 15 without switching function.
Som det fremgår af ovenstående, opnår man med et grundmodul ifølge opfindelsen en mulighed for med nogle få grunddele at opbygge flere forskellige afbrydertyper, til forskellige strømstyrker.As can be seen from the above, a basic module according to the invention provides an opportunity to build with a few basic parts several different switch types, for different currents.
20 Fig. 4 viser selve grundmodulet 30, der består af en overdel 101 og en underdel 102 og en trækstang 103. Fortrinsvis er overdelen 101 og underdelen 102 identiske. Indskæringer 134 danner åbningerne 33, som tillader stangen 32 at passere gennem grundmodulet og især gennem åbningen 84 i trækstangen 103, 25 som inde i grundmodulet af stangen 32 kan forskydes i sin længderetning. Når grundmodulet er samlet, danner de tre dele på det nærmeste et næsten lukket retvinklet parallel-epipedum. Fortrinsvis er overpart og underpart forsynet med klipseorga-ner 108, 109 til at holde de to dele tæt sammen.FIG. 4 shows the basic module 30 itself, which consists of a top part 101 and a lower part 102 and a drawbar 103. Preferably, the upper part 101 and the lower part 102 are identical. The notches 134 form the openings 33 which allow the rod 32 to pass through the base module and especially through the opening 84 in the pull rod 103, 25 which can be displaced in its longitudinal direction within the base module of the rod 32. When the basic module is assembled, the three parts form an almost closed right-angled parallel epipedum. Preferably, the upper and lower parts are provided with clip means 108, 109 for holding the two parts tightly together.
30 Fig. 5 viser et eksempel på en udførelsesform for et sæt bevægelige kontakter 123 - 125 til montering i trækstangen 103, som vist i fig. 4.FIG. 5 shows an example of an embodiment of a set of movable contacts 123 - 125 for mounting in the drawbar 103, as shown in FIG. 4th
DK 171005 B1 6DK 171005 B1 6
Kontakterne 401 og 402 er på kendt måde indrettet til at danne bro mellem to knive, dvs. faste kontakter, f.eks. 14 og 34. Kontakterne 401 og 402 trykkes imod hinanden af fjedre 406 og 407, som fastholdes af fjedersko 405. 411 og 412 er hvælvede 5 kontaktflader, som skal i berøring med de faste knivkontakter 14, 34.The contacts 401 and 402 are in a known manner arranged to bridge between two knives, i.e. fixed contacts, e.g. 14 and 34. The contacts 401 and 402 are pressed against each other by springs 406 and 407 which are held by spring shoes 405. 411 and 412 are vaulted 5 contact surfaces which are to contact the fixed knife contacts 14, 34.
Fig. 6 viser, hvorledes trækstangen 103 er opbygget af to fortrinsvis ens halvparter 121 og 122, der er indrettet til at optage tre sæt bevægelige kontakter 123, 124, 125. Fire tappe 10 90 (to i hver halvpart) er udformet således, at de kan fastholdes i fire tilsvarende huller 91. 127 og 128 er skillevægge, der skaber en adskillelse mellem de tre kontaktsæt, således at der dannes et i det væsentlige lukket brydekammer omkring hvert kontaktsæt 123 - 125, når delene er monteret i 15 grundmodulets overdel 101 og underdel 102. Hertil medvirker dog også i høj grad skillevægge 117, 118 i grundmodulets halvparter 101 og 102.FIG. 6 shows how the drawbar 103 is made up of two preferably identical half-parts 121 and 122 arranged to receive three sets of movable contacts 123, 124, 125. Four pins 10 90 (two in each half) are designed so that they can are retained in four corresponding holes 91. 127 and 128 are partitions which create a separation between the three contact sets, so that a substantially closed break chamber is formed around each contact set 123 - 125 when the parts are mounted in the upper part 101 and lower part of the basic module. 102. However, partitions 117, 118 in the basic modules half-parts 101 and 102 also largely contribute to this.
Afbryderen virker på følgende måde. Drejes afbryderens håndtag (320 i fig. 3) over i indkoblingsstillingen, medfører denne 20 drejning en tilsvarende drejning af de cylindriske dele 24 og 22. Medbringeren 23 forskyder slæden 18 og stangen 32. Åbningerne 33 er så lange, at stangen kan forskydes uden at skubbe til grundmodulernes skaller 101, 102. Åbningerne 84 i grundmodulernes trækstænger 103 er derimod så snævre, at tværstangens 25 32 bevægelse overføres til trækstængerne 103 og dermed til de bevægelige kontakter 123 - 125. På de i fig. 1 og 2 viste afbrydere vil en drejning af håndtagsakslen med uret medføre, at samtlige bevægelige kontakter 123 - 125 forskydes således, at kontakterne 401 og 402 kommer til at ligge på hver sin side af 30 et sæt knivkontakter 14, 34, som de således danner bro mellem. Tilsvarende vil en drejning af håndtagsakslen mod uret medføre, at samtlige bevægelige kontakter forskydes bort fra knivkontakterne 14, 34, således at strømmen brydes.The switch operates as follows. If the handle of the switch (320 in Fig. 3) is turned into the switch-on position, this 20 causes a corresponding rotation of the cylindrical parts 24 and 22. The carrier 23 displaces the carriage 18 and the rod 32. The openings 33 are so long that the rod can be displaced without on the other hand, the apertures 84 in the draw rods 103 of the basic modules are so narrow that the movement of the transverse rods 25 is transferred to the pull rods 103 and thus to the movable contacts 123 - 125. 1 and 2, a rotation of the handle shaft clockwise will cause all of the movable contacts 123 - 125 to be displaced such that contacts 401 and 402 will lie on each side of a set of knife contacts 14, 34, thus forming bridge between. Similarly, turning the handle shaft counterclockwise will cause all of the moving contacts to be displaced away from the knife contacts 14, 34, thus breaking the current.
