Description
Anordning ved fjernmeldingsanlegg omfattende en releanordning for alternerende tilkobling av to eller flere bilinjer til en likespenningsførende hovedlinje. Device at a remote signaling system comprising a relay device for the alternating connection of two or more secondary lines to a DC-carrying main line.
Det foreligger ofte behov for å veksle There is often a need to switch
en telefonlinje fra en sentral mellom to til-knytninger og vekslingen blir gjerne fore-tatt fra den ene tilknytning, f. eks. med en a telephone line from a switchboard between two connections and the exchange is often made from one connection, e.g. with a
vender. I mange tilfelle befinner tilknyt-ningene seg så langt fra hverandre at linjen fra venderen til det ene apparat av turns. In many cases, the connections are so far apart that the line from the inverter to one device is disconnected
praktiske grunner er ført om sentralen. practical reasons have been passed on to the central office.
Det må da gå to linjer fra venderen til sentralen. There must then be two lines from the inverter to the switchboard.
Man kan også foreta omkobling ved You can also make a switch at
hjelp av et rele i sentralen, men da har with the help of a relay in the exchange, but then have
man hittil måttet ha en ekstra linje for until now you had to have an extra line for
styring eller i hvert fall en ekstra tråd som management or at least an additional thread which
kan kobles til jord ved den ene tilknytning, can be connected to ground at one connection,
idet sentralens strømkilde i alminnelighet being the central power source in general
er jordet. Til gjengjeld kan man ved hjelp is grounded. In return, one can with help
av denne tråd eller linje samtidig koble om of this thread or line at the same time reconnect
flere linjer. several lines.
Hvis man ikke har en ekstra linje eller If you don't have an extra line or
tråd til disposisjon eller hvis en sådan faller kostbar, kan problemet løses ifølge fore-liggende oppfinnelse, og denne tar derfor thread available or if such becomes expensive, the problem can be solved according to the present invention, and this therefore takes
sikte på å unngå en slik ekstra tråd (eller aim to avoid such an extra thread (or
— hvis sentralens strømkilde ikke er jordet, — å greie seg med bare en tråd til — if the switchboard's power source is not grounded, — to manage with just one more wire
erstatning for jordforbindelse.) Dette opp-nåes ved å koble om hovedlinjen frem og replacement for earth connection.) This is achieved by switching the main line forward and
tilbake fjernstyrt fra den linje som om-kobles uten at dennes normale funksjon back remotely controlled from the line being switched without its normal function
når den er i drift, forstyrres. when it is in operation, is disturbed.
Det skal i denne forbindelse anføres at In this connection, it must be stated that
det for telefonanlegg er kjent fra tidligere that for telephone systems is known from the past
å anordne et differensialrele innskutt i en to arrange a differential relay in a
linje uten at linjens normale funksjon ve-sentlig påvirkes, men som trekker til når line without the line's normal function being significantly affected, but which draws to when
linjen jordes eller forbindes med en ekstra the line is earthed or connected to an extra
leder ved hjelp av en trykknapp eller lig-nende. Videre er det kjent å anordnet en viss omkobling av linjen foranlediget av differensialreleets operasjon. leads by means of a push button or similar. Furthermore, it is known to arrange a certain switching of the line caused by the operation of the differential relay.
Det anvendte releutstyr er tenkt som et tilleggsutstyr som kobles som et gaffel-punkt mellom sentralens normale utstyr og to eller flere av de fra sentralen utgående linjer. Disse er i den videre beskrivelse kalt bi-linjer og er benevnt BLI og BL2. Den felles linje fra releutstyret til sentralens normale utstyr er kalt hovedlinjen HL. The relay equipment used is intended as an additional equipment which is connected as a fork point between the exchange's normal equipment and two or more of the outgoing lines from the exchange. In the further description, these are called bi-lines and are named BLI and BL2. The common line from the relay equipment to the exchange's normal equipment is called the main line HL.
Oppfinnelsen angår således en anordning ved fjernmeldingsanlegg, fortrinnsvis telefonanlegg med to-trådede linjer omfattende en releanordning for alternerende tilkobling av to eller flere bilinjer til en likespenningsførende hovedlinje, hvilken releanordning består av et differensialrele The invention thus relates to a device for remote communication systems, preferably telephone systems with two-wire lines, comprising a relay device for the alternating connection of two or more secondary lines to a DC-carrying main line, which relay device consists of a differential relay
(D) innkoblet i en eller begge bilinjer og som påvirkes ved at den ene og/eller den (D) connected in one or both bus lines and which is affected by the fact that one and/or the
andre av vedkommende bilinjes linjegrener tilkobles eller frakobles jord eller en hjelpeleder. Det nye og karakteristiske er at kontakter på nevnte differensialrele eller et hjelperele kobler hovedlinjen fra den ene bilinje og til den andre bilinje og dessuten kobler likespenning til, henholdsvis fra, den bilinje som blir koblet fra, henholdsvis til, hovedlinjen på en slik måte at den bilinje som tilkobles eller frakobles jord eller en hjelpeleder alltid er tilkoblet en spenningskilde gjennom differensialreleet eller et annet rele. other of the bus line's line branches are connected or disconnected to earth or an auxiliary conductor. The new and characteristic thing is that contacts on said differential relay or an auxiliary relay connect the main line from one car line to the other car line and also connect direct voltage to, respectively from, the car line that is disconnected from, respectively to, the main line in such a way that the car line that is connected or disconnected to earth or an auxiliary conductor is always connected to a voltage source through the differential relay or another relay.
I fig. 1 og 2 er vist eksempler på utfør-elsen. I serie med linjen er innskutt de to viklinger på differensialreleet D. Disse viklinger er fortrinnsvis like og er koblet slik at den resulterende virkning av dem er til-nærmet 0 når den samme linjestrøm går gjennom begge viklinger. Når viklingene har nøyaktig samme impedans virker de som bekjent som rent ohmske motstander, når linjesløyfen er sluttet og bare gjennom releviklingene står i forbindelse med strøm-kilden. In fig. 1 and 2 show examples of the design. Interspersed in series with the line are the two windings of the differential relay D. These windings are preferably equal and are connected so that the resulting effect of them is approximately 0 when the same line current passes through both windings. When the windings have exactly the same impedance, they act as known purely ohmic resistors, when the line loop is closed and only connected to the current source through the relay windings.
Når linjesløyfen er sluttet, får man normal strømtilførsel enten gjennom viklingen på linjens anropsrele LR i sentralen og over kontakter på linjens bryterele BR (før søkeren S har oppsøkt linjen) elter gjennom mikrof<p>nmatereleet A (når søke-ren er innstillet på linjen og kontaktene BR er brutt). I begge tilfeller er differensialreleet D upåvirket, da viklingene fører samme strøm. When the line loop is closed, you get a normal power supply either through the winding of the line's call relay LR in the exchange and via contacts on the line's switch relay BR (before the searcher S has sought out the line) or through the microphone relay A (when the searcher is set on the line and the contacts BR are broken). In both cases, the differential relay D is unaffected, as the windings carry the same current.
I fig. 1 er det ved enden av bilinjen BLI vist en vender V med to faste stillinger. I den ene stilling forbindes linjegren Llb med jord. Releet D får da strøm i den ene viklingen (1—2). Hvis linjesløyfen på for-hånd var sluttet, øker strømmen noe i vikling (1—2), mens den i vikling (3—4) blir 0 eller sterkt redusert (avhengig av jord-ingsmotstanden). I begge tilfeller trekker releet D til og legger om sine kontakter. In fig. 1, a turning V with two fixed positions is shown at the end of the bus line BLI. In one position, line branch Llb is connected to earth. Relay D then receives current in one winding (1-2). If the line loop was previously closed, the current increases somewhat in winding (1—2), while in winding (3—4) it becomes 0 or greatly reduced (depending on the earthing resistance). In both cases, the relay D closes and resets its contacts.
Kontaktene 11, 12 og 15, 16 bryter linjen med releviklingene bort fra hovedlinjen HL og dermed fra den normale strøm-tilførsel, kontaktene 12, 13 og 17, 18 kobler hovedlinjen sammen med den andre bilinjen BL2 og kontakten 14, 15 kobler minus gjennom en beskyttelsesmotstand r og rele D's vikling (1—2), slik at releet holder seg tiltrukket så lenge venderen V er om-lagt. Contacts 11, 12 and 15, 16 break the line with the relay windings away from the main line HL and thus from the normal power supply, contacts 12, 13 and 17, 18 connect the main line together with the second bus line BL2 and contact 14, 15 connects minus through a protective resistance r and relay D's winding (1—2), so that the relay remains attracted as long as the inverter V is switched.
Når venderen V legges tilbake i åpen stilling blir releet D strømløst og legger sine kontakter om til den opprinnelige stilling. Releet D kan også ha andre kontakter (ikke- vist) som kan ha oppgaver utenom de ovenfor nevnte. Det er selvfølgelig heller ikke noe i veien for at noen eller alle kontaktene kan tilhøre et hjelper ele som styres av en kontakt på releet D. Hvis kontaktene 14, 15, 16 tilhører rele D, må vekslingen være såkalt kontinuerlig. When the reverser V is returned to the open position, the relay D becomes de-energized and resets its contacts to the original position. The relay D may also have other contacts (not shown) which may have tasks other than those mentioned above. Of course, there is also nothing to prevent some or all of the contacts from belonging to an auxiliary relay which is controlled by a contact on relay D. If contacts 14, 15, 16 belong to relay D, the switching must be so-called continuous.
I fig. 2 er det anordnet en ikke selv-sperrende trykknapp T, som, når den trykkes ned legger jord på den ene linjegren, 1 dette tilfelle på L la for at ikke linjereleet LR skal påvirkes, hvis ikke også linjesløy-fen samtidig er sluttet. Valget av linjegren som jordes er ikke avgjørende, men i dette tilfelle er valgt den linjegren som normalt ligger til jord på sentralen, for at den som foretar omkoblingen skal være nødt til å løfte av mikrotelefonen og kontrollere kob-lingens tilstand før knappen trykkes ned. In fig. 2, a non-self-locking push button T is arranged, which, when pressed, places earth on one line branch, 1 in this case on L so that the line relay LR is not affected, if the line loop is not closed at the same time. The choice of line branch to be grounded is not decisive, but in this case the line branch which is normally grounded on the switchboard has been chosen, so that the person making the switch will have to lift the handset and check the condition of the connection before pressing the button.
De kontakter som omkobler linjene og eventuelle kontakter for andre formål, er her anbragt på ett eller flere hjelpereteer i en kjent relekobling av den art som veksler mellom to eller flere forskjellige tilstander hver gang den påvirkes av en eller flere kontakter, i eksempelet av kontaktene 21, 22 på rele D. The contacts that switch the lines and any contacts for other purposes are here placed on one or more auxiliary tracks in a known relay connection of the kind that alternates between two or more different states each time it is affected by one or more contacts, in the example of the contacts 21 , 22 on relay D.
Den i og for seg kjente relekobling for releene X og Y som er vist på fig. 2, virker på følgende måte: Når D slutter kontakt 21, 22, får både X og Y strøm i sine viklinger 1—2. Releet X trekker til, men releet Y får dessuten strøm i den motvirkende vikling, Y (3—4), og trekker ikke til. Når D The per se known relay connection for the relays X and Y shown in fig. 2, works in the following way: When D closes contact 21, 22, both X and Y receive current in their windings 1—2. Relay X energizes, but relay Y also receives current in the counteracting winding, Y (3-4), and does not energize. When D
åpner kontakten igjen fortsetter strømmen i vikling 1—2 på både X og Y, og da strøm-men i Y (3—4) nå er brutt av D 21, 22, trekker Y til. Både X og Y står nå tiltrukket. Y's kontakter Yll, 12 og Y 31, 32 har opens the contact again, the current continues in winding 1—2 on both X and Y, and as the current in Y (3—4) is now broken by D 21, 22, Y draws. Both X and Y are now attracted. Y's contacts Yll, 12 and Y 31, 32 have
nå koblet viklingene på releet D bort fra den normale strømtilførsel over hovedlinjen HL, og denne er koblet sammen med den annen bilinje BL2 over kontaktene Y 14, 15 now the windings of the relay D are disconnected from the normal power supply over the main line HL, and this is connected to the other car line BL2 over the contacts Y 14, 15
og Y 34, 35. Kontakten Y 32, 33 har koblet minus via motstanden r og viklingen 3—4 på rele D til den ene gren av bilinje BLI (L lb), slik at dette rele fremdeles kan trekke til, når det ønskes. and Y 34, 35. The contact Y 32, 33 has connected minus via the resistor r and the winding 3-4 on relay D to one branch of bus line BLI (L lb), so that this relay can still energize when desired.
Så lenge denne koblingstilstand opp-rettholdes (releene X og Y er tiltrukket) er et hørbart signal (opt.) via en konden-sator tilkoblet linje BLI. As long as this switching state is maintained (relays X and Y are energized) an audible signal (opt.) via a capacitor connected to line BLI.
Når hovedlinjen HL igjen ønskes tilkoblet bilinje BLI, sluttes linjesløyfen igjen (ved at mikrotelefonen løftes av) og der-etter trykkes knappen T. Releet D får da strøm fra minus via motstand r, kontakt Y 33, 32, vikling D (3—4), linjesløyfen, trykknappen T til jord. Releet trekkes til og kontakt D 21, 22 sluttes. Releet X får da strøm i den motvirkende vikling 3—4, og faller. Kontakt X 21, 22, 23, legges om til normal-stilling, men viklingene 1—2 på releene X og Y får fremdeles strøm over D 21, 22. Når knappen T slippes, faller D igjen og da faller også Y. When the main line HL is again desired to be connected to the car line BLI, the line loop is closed again (by lifting the microphone) and then the button T is pressed. The relay D then receives current from minus via resistance r, contact Y 33, 32, winding D (3—4 ), the line loop, push button T to ground. The relay is pulled in and contact D 21, 22 is closed. The relay X then receives current in the counteracting winding 3-4, and drops. Contact X 21, 22, 23 is switched to the normal position, but windings 1—2 on relays X and Y still receive current via D 21, 22. When button T is released, D drops again and then Y also drops.
Situasjonen er nå den opprinnelige, og den som trykket på knappen kontrolle-rer dette. Det hørbare signalet (opt.) er nemlig nå borte og isteden fåes på normal måte f. eks. summetone fra sentralen som tegn på at linjen er tilkoblet. The situation is now the original, and whoever pressed the button controls this. The audible signal (opt.) is now gone and instead is obtained in the normal way, e.g. dial tone from the exchange as a sign that the line is connected.
De kontakter som legger om linjen kan naturligvis fordeles på releene X og Y, men den kontakt 31, 32, |33 som veksler mellom linjens normale minuspol og minus gjennom motstand r bør tilhøre rele Y, da dette rele trekker til eller faller bare hver gang rele D er falt. Av balansehensyn bør også kontakt 11, 12, 13 tilhøre Y. I alminnelighet vil man foretrekke at også kontaktene 14, 15 og 34, 35 tilhører Y. The contacts that reset the line can of course be distributed among the relays X and Y, but the contact 31, 32, |33 that alternates between the line's normal minus pole and minus through resistance r should belong to relay Y, as this relay only pulls or drops each time relay D is dropped. For reasons of balance, contacts 11, 12, 13 should also belong to Y. In general, one would prefer that contacts 14, 15 and 34, 35 also belong to Y.
På releene X og Y kan man naturligvis også ha kontakter for andre formål enn de nevnte. Kontakt 12, 13 til jord er ikke nødvendig av koblingsmessige grunner, men er bare returvei for signalet (opt.). Signalet er heller ikke strengt tatt nødven-dig. Relays X and Y can of course also have contacts for purposes other than those mentioned. Contact 12, 13 to earth is not necessary for connection-related reasons, but is only a return path for the signal (opt.). Nor is the signal strictly necessary.
I fig. 3 er vist et eksempel hvor koblingen kan styres fra begge bilinjer BLI og BL2. Disse får da hver sitt differensialrele Dl og D2, men felles hjelpereleer X og Y. Kontaktene 21, 22 på begge releer D er pa-rallellkoblet og virker hver for seg akkurat som i foregående eksempel. I begge kob-lingstilstander (releene X og Y ute eller inne) kan man med hvilken som helst av trykknappene Tl og T2 bringe koblingen i motsatt tilstand. Den bilinje som ikke er tilkoblet hovedlinjen er tilkoblet det hør-bare signal. In fig. 3 shows an example where the connection can be controlled from both bus lines BLI and BL2. These then each get their own differential relays D1 and D2, but common auxiliary relays X and Y. The contacts 21, 22 on both relays D are connected in parallel and work separately just as in the previous example. In both switching states (relays X and Y out or in), you can use any of the push buttons T1 and T2 to bring the switching to the opposite state. The car line that is not connected to the main line is connected to the audible signal.
I fig. 4 er vist et eksempel, hvor den styrende funksjon er fordelt på begge bi-linjer på en slik måte at man på hver av bilinjene bare kan koble egen linje fra og koble den annen bilinje til hovedlinjen. Den styrende bilinje er da den som i øyeblikket er tilikoblet hovedlinjen gjennom differensialreleet D. Det er selvfølgelig ikke noe i veien for at differensialreleet kan settes ut av funksjon, når bilinje 2 er opptatt i forbindelse med hovedlinjen. Dette kan gjøres på flere i og for seg kjente måter, f. eks. ved hjelp av et i serie med linjen BL2 innkoblet ekstra rele som arbeider når denne linje er strømførende. I eksemplet ifølge fig. 1 kan f. eks. en sluttekontakt på et ekstrarele (ikke vist) opprettholde jord-potensialet på linjen, Slik at rele D fortsetter å være tiltrukket når venderkontak-ten V åpnes, men faller idet ekstrareleet faller, når linje BL2 og dermed hovedlinjen blir ledig. I eksemplet ifølge fig. 2 kan en brytekontakt på et ekstrarele (ikke vist) innkobles i serie med kontakt D 21, 22 og derved oppheve virkningen av releet. Trykknappen T får derfor heller ingen virkning uten at bilinje BL2 og dermed hovedlinjen er ledig. In fig. 4 shows an example, where the controlling function is distributed over both bi-lines in such a way that on each of the car lines you can only disconnect your own line and connect the other car line to the main line. The controlling car line is then the one that is currently connected to the main line through the differential relay D. There is, of course, nothing to prevent the differential relay being put out of action, when car line 2 is busy in connection with the main line. This can be done in several known ways, e.g. by means of an additional relay connected in series with line BL2 which works when this line is live. In the example according to fig. 1 can e.g. a closing contact on an extra relay (not shown) maintains the earth potential on the line, so that relay D continues to be attracted when the reversing contact V is opened, but drops as the extra relay drops, when line BL2 and thus the main line becomes vacant. In the example according to fig. 2, a breaking contact on an additional relay (not shown) can be connected in series with contact D 21, 22 and thereby cancel the effect of the relay. The pushbutton T therefore also has no effect unless car line BL2 and thus the main line is free.
