CLASS INTERNATIONAL SWEDISH H 02 f21 c: 21/01 PATENT AND REGISTRATION AGENCY Ans. 11 504/1957 was received on 18/12 1957 issued on 25111 1963 J EISERT, ESSEN, THE FEDERAL REPUBLIC OF GERMANY Series clamp for switchgear Priority begtird Pan on 27 December 1956 (Federal Republic of Germany) direction of movement movable connecting piece breakable current path Between the connecting piece by means of two clamping screws In the prescribed closing layer, where they had clamping pieces, the connection of which can be broken, Aro connected to each other. The change of the connecting piece Iran closing law to breaking law or vice versa requires application and relocation of the tool several times, whereby the handling becomes time-consuming and permanent. The relatively large number of operating operations required for multi-phase test couplings, each of which must be carried out with care, meant the carriage, which could jeopardize the operational safety of the coupling system as well as the power supply. Inadvertently, an involuntary loosening of the clamping screws is observed during operation at the known series clamps for coupling systems.
Serieklammor for kopplingsanlaggningar Aro aven kanda, dar fOrbindningsstycket i slutningslage medelst en enda klamskruv. Vid dessa serieklammor Mlles klamskruven i en isolerkropp, och forbindningsstycket ar utbildat som en efter klamskruvens lossnande ornkring denna fiirstallbar brygga. I detta fall Lag& det forhallandet, att brytstallet icke ãr omedelbart synligt, en sarsIdld fara. Series clamps for coupling systems Aro aven kanda, where the connecting piece is in the closing position by means of a single clamping screw. At these series clamps, the clamping screw is milled in an insulating body, and the connecting piece is formed as a bridge which can be detached after the clamping screw comes loose. In this case, the law that the breaker is not immediately visible is a very dangerous danger.
Uppfinningen har stallt sig den uppgiften att utbilda en serieklamma pa sadant satt, att en flerfaldig omflyttning av verktyget icke skall erfordras for att forandra forbindningsstyckets kopplingslage. I princip skall darvid paverkan av forbindningsstycket kumm ske raedelst en vanlig skruvmejsel, och darjamte skall f6rbindningsstycket i slutningslaget eller ett liknande kopplingslage vara sakrat mot oavsiktligt lossnande av forbindningsstyckets klamskruv. The invention has set itself the task of forming a series clamp in such a way that a multiple relocation of the tool is not required to change the coupling position of the connecting piece. In principle, the connection of the connecting piece kumm shall be effected by means of an ordinary screwdriver, and in addition the connecting piece in the closing layer or a similar coupling layer shall be secured against unintentional loosening of the clamping screw of the connecting piece.
Uppfinningen avser en serieklamma for kopplingsanlaggningar, vars genom anslut- ningsklanistycken bildade brutna strombana är brytbar genom ett i langdriktningen forskjutbart forbindningsstycke, och den bestar dari, att klarakroppens anslutningsklamstycken vid brytstallet skjuta fram med utlopare och att forbindningsstycket bestar av en pa utloparna liggande overdel liksom av en i resp. pa en glidbana ford underdel och att for paverkan fOrbindningsstyckets hada delar aro forbundna genom en enda klamskruv. Klamskruven är i enlighet med uppfinningen ytterligare utbildad till en installnings-, forflyttnings- och fasthallningsanordning for forbindningsstyeket. Klamskruvens vanliga funktion att fasthalla fOrbindningsstycket i slutningslage eller ett liknande kopplin.gslage f Orverkligas vid serieklamman enligt uppfinningen darigenona, att klamskruven, pa vilken forbindningsstyeket iir fOrt sakrat mot vridrorelse men losbart eller fastsattningsbart genom skruvrorelse hos klamskruven, stOder sig mot ett glidunderlag pa isolerkroppen och spanner in de hada klamstycken, som skola forbindas, mellan metallbryggor. En. foretradesvis anvand utforingsform, som visat sig uppfylla stallda krav, uppnar ett fasthallande av forbindningsstycket genom tva skruvstadsaktiga delar has anslutningsklamstyckena, vilka skola fOrbindas, verkande klambackar, vilka genom forbindningsstyckets klamskruv kunna bringas i spannlage. Fransett den vanliga funktionea att fasthalla forbindningsstycket fyller darvid den i forbindningsstycket skruvade klamskruven i enlighet med uppfinningen en ny och vasentlig funktion, eftersom forbindningsstycket med hjalp av verktyget I Or klamskruvens lossnande genom inverkan pa klamskruven samtidigt an omstallbart for brytande av strombanan eller f6r astadkommande av slutning av denna eller for install-fling av andra kopplingslagen utan borttagande av verktyget och utan att ytterligare verktyg behova tagas i bruk. The invention relates to a series clamp for coupling systems, the broken current path formed by connecting clan pieces is breakable by a longitudinally displaceable connecting piece, and it consists in that the connecting body pieces of the clear body at the breaking point project with outlets and that the connecting piece consists of an upper part. one in resp. on a slide for the lower part and that for the effect the connecting parts of the connecting piece are connected by a single clamping screw. In accordance with the invention, the clamping screw is further formed into an installation, transfer and holding device for the connecting piece. The usual function of the clamping screw is to hold the connecting piece in the closing position or a similar coupling type. spans the hada clamp pieces, which are to be connected, between metal bridges. One. preferably used embodiment, which has been found to meet the set requirements, achieves a holding of the connecting piece through two screw-like parts has the connecting clamping pieces, which are to be connected, acting clamping jaws, which can be brought into tension by the clamping screw of the connecting piece. In addition to the usual function of holding the connecting piece, the clamping screw screwed into the connecting piece in accordance with the invention fulfills a new and essential function, since the connecting piece with the aid of the tool I or the clamping screw loosening by acting on the clamping screw can be switched to break the current path or end. of this or for installation of other coupling layers without removal of the tool and without the need for additional tools to be used.
Vid den utforingsform, vars forbindnings- 2— — stycke bestar av tvâ skruystadsaktigt verkande delar, fores det ph ena sidan mot anslutningsklamstyckenas ledytor anliggande undre styeket ph en pa isolerkroppen utbildad och hven mom det omrade, dar anslutningsstycket har avbrott, slat genomgaende glidbana, varigenom forhindras att hamning intruder vid forskjutning av forbindningsstycket. 1/id mindre hoga ansprdk kan det senare ftirhallandet aven uppnas darigenom, att det undre delstycket med nagot glapp kan rora sig i ett mellanrum melIan anslutningsklamstyckenas anliggningsoch forskjutningsytor och isolerkroppen. In the embodiment whose connecting piece consists of two helically acting parts, the lower side abuts the connecting piece of the connecting clamping pieces on one side and is formed on the insulating body and in the area where the connecting piece is interrupted, through a continuous slide, through which prevention of intrusion occurs when the connecting piece is displaced. In the case of less high demands, the latter holding can also be achieved in that the lower part can with some play move in a space between the abutment and displacement surfaces of the connecting clamp pieces and the insulating body.
For att underlatta avbrott eller slutning genom forskjutning av forbindningsstycket med hjalp av det for klamskruvens omstallning erforderliga verktyget, är det att rekommendera att i enlighet med uppfinningen anvanda en klamskruv med ett med skruvskara for-sett huvud, varvid skruvskaran, exempelvis genom en huvudet omgivande krage eller genom utsprdng, som stanga till skaran vid kanterna, är sh anordnad, att skruvmejseln joke vid nagon stallning av skruven kan glida ut ur skaran. In order to facilitate interruption or closure by displacing the connecting piece by means of the tool required for the adjustment of the clamping screw, it is recommended to use in accordance with the invention a clamping screw with a head provided with a screw hole, the screw hole, for example through a head surrounding the collar. or by spreading, as a rod to the crowd at the edges, it is arranged that the screwdriver joke can slide out of the crowd at any positioning of the screw.
De genom uppfinningen ernadda fordelarna besta framfor alit dari, att genom anbringande av ett handverktyg, foretradesvis en vanlig skruvmejsel, en. enda gang, och darmed praktiskt taget med en enda manover, är en andring av det forskjutbara forbindningsstyckets kopplingslage mojlig. Denna forenkling i handhavandet medfor samtidigt en hojning av sakerheten hos hela kraftverksdriften och stromforsorjningen, eftersom pa samma gang sannolikheten for liksoiu mojligheten till manskliga felgrepp vid kopplingsarbeten pd serieklammorna ar vasentligt minskad. En minskning av sannolikheten for mansIdiga felgrepp uppnas framfor alit genom det i forhallande till de kanda serieklammorna mangfaldigt minskade antalet handgrepp, och en minskning av mojligheten till manskliga felgrepp intrader sarskilt darigenom, att vid den oftast vanliga och darfOr av uppfinningen sarskilt berorda vertikala anordningen av forbindningsstyckets forskjutningsstracka vid i enlighet med uppfinningen utforda serieklammor forbindningsstycket yid bristande tilldragning av klamskruven genom tyngdkraften Iran slutningslaget faller ned till brytlage. Ett bortglommande av att draga at klamskruven, vilket medfor storningar, liksom den darigenom vid vanliga kanda kopplingsanlaggningar mojliga daliga elektriska f8rbindningen mellan anslutningsklamstyckena, iir darfor praktiskt taget uteslutet. The advantages obtained by the invention exist above all in that, by applying a hand tool, preferably an ordinary screwdriver, a. once, and thus practically with a single maneuver, a change of the coupling position of the displaceable connecting piece is possible. At the same time, this simplification of operation increases the safety of the entire power plant operation and the power supply, since at the same time the probability of the likelihood of human error in coupling work on the series clamps is significantly reduced. A reduction in the probability of human error is achieved above all by the manifold decrease in the number of hand grips manifolds in relation to the known series clamps, and a reduction in the possibility of human error occurs in particular by the fact that in the most common and therefore of the invention special connection of the vertical device. displacement distance at in accordance with the invention challenge series clamps connecting piece yid lack of tightening of the clamping screw by gravity Iran the closing layer falls down to the breaking layer. A failure to tighten the clamping screw, which entails disturbances, as well as the possible electrical connection between the connection clamping pieces which is thereby possible in ordinary connector systems, is therefore practically excluded.
Till att ytterligare hoja driftsakerheten hos kopplingsanlaggningen och stromforsorjningen tjana atgarder i enlighet riled uppfinningen, vilka ha sjalvstandig betydelse och besta. dari, att forbindningsstyckets klamskruv är forsedd med en sakring mot oavsiktligt lossnande, vilket vid enligt uppfinningen utforda serieklammor kan ernas pa sardeles enkelt Ott. I enlighet med uppfinningen foreslas att sakra klamskruvarna for anslutningsklamstyckena liksom forbindningsstyckets klamskruv och eventuellt forefintliga klamskruvar for hjalpanslutningar mot oavsiktligt lossnande enligt ett och samma sakringssystem, sã. att vid alla klam- och forbindningsstallen mekaniskt ekvivalenta forhallanden rada. Sakring av klamskruvarna mot oavsiktligt lossnande kan ske darigenom, att de med gangor forsedda delar, i vilka klamskruvarna skruvas in, aro forsedda med ytterligare bromsbackar, vilka hro forsedda med gangor och tjana som gangstyrning fOr klamskruvarna och vid tilldragning av klamskruvarna trada i verksamhet sasom bromsar. Enligt en. foretradesvis anvand utforingsform aro harvid bromsbackarna anordnade pa avstand fran de vanliga, med gangor forsedda delarna (huvuddelen), men den vanliga och med gangor forsedda delen kan aven overga i en bromsback. In order to further increase the operational reliability of the switching system and the power supply, measures in accordance with the invention serve, which have independent significance and existence. in that the clamping screw of the connecting piece is provided with a locking ring against unintentional loosening, which in the case of series clamps which can be challenged can be obtained in a very simple manner. In accordance with the invention, it is proposed to secure the clamping screws for the connecting clamping pieces as well as the clamping screw of the connecting piece and any existing clamping screws for auxiliary connections against unintentional loosening according to one and the same securing system, so. that at all clamp and connection stalls mechanically equivalent conditions prevail. Securing the clamping screws against unintentional loosening can be done by the parts provided with passages, in which the clamping screws are screwed, being provided with additional brake jaws, which are provided with passages and serve as a guide for the clamping screws and when tightening the clamping screws. . According to a. Preferably, the embodiment used is in which the brake shoes are arranged at a distance from the usual parts provided with passages (the main part), but the usual and provided parts with passages can also merge into a brake shoe.
For det fall att vid serieklammor enligt uppfinningen hjalpanslutningar aro anordnade, ãr det lampligt att anordna de sistnamnda pa hada sidor om forbindningsstyckets fOrskjutningsyta och begransa fOrbindningsstyckets forskjutningsbana genom dessa hjalpanslutningar, liksom att som hjalpanslutningar anordna ph anslutningsklamstyckena medelst exempelvis de pa motsvarande satt genomga.- ende klamskruvarna fOr en hjalpanslutning fastskruvade hjalpanslutningsblock., vilka 118- ja sig Over forbindningsstyckets klamskruv, sh att hjalpanslutningsledarna kunna WU& ras ovanThr klumskruvarna. Hjalpanslutningsklammorna kunna harigenom latt ersattas av propphylsor och liknande, nar sá erfordras f8r bestamda provnings-, matnings- eller driftsandamal. Det âr aven mojligt att kombinera hjalpanslutningsklammorna med fasta eller omkopplingsbara tvarbryggor. Foretra.- desvis valjes uppbyggnaden darvid pa &Want suit, att hjalpanslutningarna anbringas omedelbart intill forbindningsstyckets forskjutningsytor ph anslutningsklamstyckena, medan klainskruvarna for driftanslutningarna aro inskruvade i anslutningsldamstyckena in-till och utanfOr hjalpanslutningarna. In the case that in the case of series clamps according to the invention auxiliary connections are arranged, it is appropriate to arrange the latter on either side of the displacement surface of the connecting piece and to define the displacement path of the connecting piece through these auxiliary connections, as well as to arrange the corresponding terminal clamps as auxiliary connections. the clamping screws for an auxiliary connection screwed on the auxiliary connection blocks, which 118- yes themselves Above the connecting piece clamping screw, sh that the auxiliary connection conductors can WU & ras aboveThr the clamping screws. The auxiliary connection clamps can thus be easily replaced by plug sleeves and the like, when required for specific test, feed or operating purposes. It is also possible to combine the auxiliary connection clamps with fixed or switchable cross bridges. Preferably, the construction is chosen by & auxiliary suit, that the auxiliary connections are arranged immediately next to the displacement surfaces of the connecting piece ph the connection clamp pieces, while the small screws for the operating connections are screwed into the connection damper pieces in and out of the auxiliary connections.
Markanordningar aro vid enligt uppfinningen utforda serieklammor anordnade under provledaranslutningarna. Ground devices are according to the invention challenging series clamps arranged under the test conductor connections.
Brytklamman enligt uppfinningen kannetecknas a-yen sarskilt darav, att forbindningsstycket och kontaktstallena ha areor, som aro lika stora som eller stone an arean hos den groysta ledare, vilken kan anslutas till klamman. The breaking clamp according to the invention can be characterized a-yen in particular by the fact that the connecting piece and the contact stalls have areas which are equal to or stone the area of the grooved conductor, which can be connected to the clamp.
Uppbyggnaden av en enligt uppfinningen utford serieklamma jamte infastningen och anordnandet av klamstyckena i isolerkroppen är i och for sig godtycklig. Foretradesvis anvandes dock en principiell uppbyggnad, som — —3 kannetecknas darav, att saval driftanslutningarnas klamskruyar som fOrbindningsstyckets klamslumv och fOretradesvis aven de stallen, dar markbararna anordnas, aro forlagda djupare an hjalpanslutningarnas klamskruvar. Klamman blir harigenom synnerligen latt all handskas med, driftanslutningarna kunna lätt anbringas, och utan hinder haray, och omvant utan att hindra, kunna hjalpledningar, sisom provtradar och Sven kortslutningsstycken, fastas pa hjalpklamskruvarna. Eftersom enligt uppfinningen genom en brytspalt atskilda anslutningsklamstycken bilda en glidoeh upplagsyta for det forskjutbara forbindningsstycket, är det fordelaktigt om klamstyckena aro oforskjutbart fixerade ifraga om sina lagen i isolerkroppen. Detta ernas enlist uppfinningen darigenom, att fjadrande utsprang aro anbragta p anslutningsklamstyckena och att dessa aro fixerade med hj alp av fjadrande utsprang, samt i ovrigt genom anliggningsytor i isolerkroppen. The construction of a series clamp according to the invention challenges the fastening and the arrangement of the clamping pieces in the insulating body is per se arbitrary. Preferably, however, a basic structure is used, which can be characterized by the fact that both the clamping screws of the operating connections as the clamping sludge of the connecting piece and preferably also the stalls where the ground bars are arranged are located deeper than the clamping screws of the auxiliary connections. The clamp is thus extremely easy to handle, the operating connections can be easily attached, and without hindrance haray, and vice versa without hindrance, auxiliary lines, such as test wires and Sven short-circuit pieces, can be fastened to the auxiliary clamp screws. Since, according to the invention, the connecting clamping pieces separated by a breaking gap form a sliding support surface for the displaceable connecting piece, it is advantageous if the clamping pieces are fixedly fixed in accordance with their layers in the insulating body. This is in accordance with the invention in that resilient projections are arranged on the connecting clamp pieces and that these are fixed by means of resilient projections, and otherwise through abutment surfaces in the insulating body.
Uppfinningen beskrives i det fOljande närmare i anslutning till ett ph ritningen visat utforingsexempel. Fig. 1 ãr en sidovy av en enligt uppfinningen utford serieklamma for kopplingsanlaggningar. Fig. 2 är en frontvy av den i fig. 1 visade klb.mman. Fig. 3 är ett snitt enligt linj en A—A i fig. 1. Fig. 4 är ett snitt enligt linjen B—B i fig. 1, och fig. 5 ett mot fig. 4 svarande snitt genom ett annat utforande av klhmskruvens bromssystem. The invention is described in more detail below in connection with an embodiment shown in the drawing. Fig. 1 is a side view of a series clamp for coupling systems according to the invention. Fig. 2 is a front view of the clutch shown in Fig. 1. Fig. 3 is a section along line one A — A in Fig. 1. Fig. 4 is a section along the line B — B in Fig. 1, and Fig. 5 is a section corresponding to Fig. 4 through another embodiment of the clamping screw. braking system.
Den pa ritningen visade serieklamman for kopplingsanlaggningar har anslutningsklamstycken 1 och 2, vilka aro fastsatta i en isolerkropp 3 och genom ett med en enda klamskruv 4 klambart omstallbart forbindningsstycke 5 kunna skiljas frau varandra. FOr detta andamal finnes mellan anslutningsklammorna 1 och 2 ett motsvarande mellanrum 6. Forbindningsstycket 5 bestar av tva skruvstadaktigt pa de delar av anslutningsklamstyckena 1 och 2, som skola forbindas med varandra, verkande delstycken 5a och 5b, av vilka det undre 5b är forsett med en ganga 7, i ett pa skruven medfort bryggstycke. Det med ganga fOrsedda undre delstycket 5b fores a ena sidan mot ledytor 8 pa klamstyckena och pa andra sidan mot en pa isolerkroppen 3 utbildad ledbana 9. Forbindningsstyckets 5 klamskruv 4 har ett med skara forsett huvud 10, vars skara 11 Sr utbildad med tillslutna andar genom en huvudet omgivande krage 12. Sasom visas pa ritningen är anordningen sadan, att forbindningsstyckets 5 forskjutningsstracka vid inbyggda klammor gar i vertikal riktning och pa sadant satt, att vid lossad klamskruv 4 forbindningsstycket 5 fal- ler ned i brytlage. Farbindningsstycket 5 har erhallit en sa.dan profil, att dess stromforande area är lika med eller stOrre fin den stromfOrande arean hos ovriga delar hos klamman, dvs. anslutningsklamstyckena 1, 2, resp. hos strombanan. The series clamp for coupling systems shown in the drawing has connecting clamp pieces 1 and 2, which are fixed in an insulating body 3 and can be separated from each other by a connectable piece 5 which can be clamped with a single clamping screw 4. For this purpose, there is a corresponding space 6 between the connection clamps 1 and 2. The connecting piece 5 consists of two screw-fixed parts of the connecting clamp pieces 1 and 2, which are to be connected to each other, acting sub-pieces 5a and 5b, of which the lower 5b is provided thread 7, in one on the screw carried bridge piece. The threaded lower part 5b is lined on one side against joint surfaces 8 on the clamp pieces and on the other hand against a guide track 9 formed on the insulating body 3. The clamping screw 4 of the connecting piece 5 has a notched head 10, whose groove 11 is formed with closed spirits by a collar 12 surrounding the head 12. As shown in the drawing, the device is such that the displacement distance of the connecting piece 5 at built-in clamps goes in the vertical direction and in such a way that when the clamping screw 4 is loosened the connecting piece 5 falls into the breaking layer. The connecting piece 5 has obtained such a profile that its current-carrying area is equal to or greater than the current-carrying area of other parts of the clamp, i.e. the connection clamp pieces 1, 2, resp. at the power line.
Av ritningen framgar vidare, att forbindningsstycket 5 kan sattas fast resp. forskju- tas med hjalp av en skruvmejsel, varfor med ett enda verktyg och i ett enda arbetstempo forbindningsstycket 5 Sr forskjutbart nedat och strombanan harigenom brytbar. The drawing further shows that the connecting piece 5 can be fastened resp. is displaced by means of a screwdriver, wherefore with a single tool and at a single working speed the connecting piece 5 is slidably downwards and the current path is thereby breakable.
For att undvika oavsiktligt lossnande av forbindningsstyckets 5 klamskruv 4 forefinnes en sakring, vilken bestar av de i fig. 3, 4- och 5 visade bromsbackarna 13. Bromsbackar 13 aro anbringade pa avstand fran en med. gangor forsedd del 11 icke blott pa forbind- ningsstycket 5 utan Sven ph alla de klam- delar, i vilka klamskruvar 4, 15, 16 aro inskruvade.

In order to avoid unintentional loosening of the clamping screw 4 of the connecting piece 5, there is a locking ring, which consists of the brake shoes 13 shown in Figs. 3, 4- and 5. Brake shoes 13 are arranged at a distance from one another. gangways provided part 11 not only on the connecting piece 5 but Sven ph all the clamping parts, in which clamping screws 4, 15, 16 are screwed. In the embodiment shown, the clamping screws 15 and the connecting pieces 1, 2 as well as the clamping screws 16 for the auxiliary connections 17 are shown. The brake shoes 13 are shown particularly clearly in Fig. 4 and Fig. 5. The brake shoes 13 are arranged at a distance from the usual passages. the parts 14 and preferably, as indicated in Fig. 5, arranged separately from them.
As ritningsfigurerna framgar, att hjalpanslutningarna aro anordnade pa bada sidor om forbindningsstyckets 5 forskjutningsbana, sa att forbindningsstyckets 5 forskjutningsbana Sr begransad genom dessa hjalpanslutningar 17. Hjalpanslutningarna 17 aro sjalva bildade av hjalpanslutningsblock 17a, som aro styrda pa klamskruvarna 16 for dessa hjalpanslut- ningar, vilka klamskruvar S sin sida aro in- skruvade i anslutningsklamstyckena 1, 2 och fOrsedda med sakringar av forut angiven typ for forhindrande av oavsiktligt lossnande. Det Sr mOjligt att utbyta dessa hjalpanslutningsblock 17a mat a. ritningen icke visade hjalpan- slutningshylsor. Klamskruvarna 15 for drift- anslutningarna befinna sig omedelbart intill hjalpanslutningarna 17. De aro sakrade ph samma salt som de tidigare beskrivna klam- skruvarna 4, 16. Bredvid de sistnamnda klamskruvarna 15 befinna sig snedstallda mark- skyltar 18, vilka pa detta stalle aro val synliga och kunna vara utforda med olika far-gem. As the drawing figures show, the auxiliary connections are arranged on both sides of the displacement path of the connecting piece 5, so that the displacement path S of the connecting piece 5 is delimited by these auxiliary connections 17. The auxiliary connections 17 are themselves formed by auxiliary connection blocks 17a, which are guided on clamps 16 clamping screws S its side are screwed into the connecting clamp pieces 1, 2 and fitted with retaining rings of the previously specified type to prevent accidental loosening. It is possible to replace these auxiliary connection blocks 17a with food a. The drawing does not show auxiliary connection sleeves. The clamping screws 15 for the operating connections are located immediately next to the auxiliary connections 17. They are secured with the same salt as the previously described clamping screws 4, 16. Next to the latter clamping screws 15 there are inclined ground plates 18, which in this case are selectively visible. and be able to be challenged with different colors.
