Description
Oppfinnelsen angår en overvåkningskobling som mates med likestrøm og er utført i samsvar med hovedkravets innledning. The invention relates to a monitoring link which is supplied with direct current and is made in accordance with the introduction of the main claim.
Ved slike overvakningskoblinger slik de særlig anvendes ved innføring av meldinger fra fjernstyringsapparater, blir der f.eks. In the case of such monitoring links, as they are particularly used when introducing messages from remote control devices, there will e.g.
for lastbryteres hjelpebryterkontakter som skal testes, som omsetningselementer benyttet releer hvis vikling danner en til-strekkelig belastning for hjelpebryterkontaktene for ved åpning å bevirke lysbuer og dermed befri kontaktdelene for asbest- for the auxiliary switch contacts of load switches to be tested, as switching elements used relays whose winding forms a sufficient load for the auxiliary switch contacts to cause electric arcs when opened and thus free the contact parts from asbestos
og oksydsikt. Selve relékontaktene kan med liten belastning be-tjene meldekretser. Ved fjernstyringsapparater er et stort antall hjelpebryterkontakter som skal testes^, tillike med et til-svarende antall omsetningselementer anbragt på trang plass (som stikkbare koblingsplater eller lignende) i koblingsskap. Da reléviklinger så vel som motstander som benyttes som omsetningselementer, omsetter den via hjelpebryterkontaktene overførte effekt til varme, behøves kostbare kjøleanordninger for å unngå skadelige temperaturer. For å unngå dette har man forsøkt å ned-sette den elektriske belastning av hjelpebryterkontaktene, noe som i høy grad truer påliteligheten av overvåkningen, eller man har plassert omsetningselementene lenger fra hverandre i rommet, noe som fører til meldeanlegg med større utstrekning (større koblingsskap, større avstand mellom koblingselementene). and oxide visibility. The relay contacts themselves can serve signaling circuits with little load. In the case of remote control devices, a large number of auxiliary switch contacts to be tested^, together with a corresponding number of switching elements, are placed in a tight space (such as pluggable connection plates or the like) in a switch cabinet. Since relay windings as well as resistors used as conversion elements convert the power transferred via the auxiliary switch contacts into heat, expensive cooling devices are needed to avoid harmful temperatures. To avoid this, attempts have been made to reduce the electrical load on the auxiliary switch contacts, which greatly threatens the reliability of the monitoring, or the switching elements have been placed further apart in the room, which leads to reporting systems with a larger extent (larger switch cabinets, greater distance between the connecting elements).
Til grunn for oppfinnelsen ligger den oppgave å skaffe en kompakt overvåkningskobling av den innledningsvis nevnte art, The invention is based on the task of providing a compact monitoring link of the type mentioned at the outset,
hvor varmeutviklingen i omsetningselementene til tross for til-strekkelig stor belastning på koblingskontaktene som skal over-våkes, blir holdt vesentlig lavere og der skjer en tilbakeleve-ring av strøm til den ytre strømkrets. where the heat development in the turnover elements, despite the sufficiently large load on the switching contacts to be monitored, is kept significantly lower and there is a return of current to the external circuit.
Løsningen av den angitte oppgave lykkes med de trekk som er angitt i hovedkravets karakteristikk. The solution of the specified task is successful with the features specified in the main requirement's characteristics.
Et utførelseseksempel på oppfinnelsen vil i det følgende An embodiment of the invention will follow
bli belyst nærmere ved en sterkt forenklet kobling. be elucidated in more detail by a greatly simplified connection.
* Til en ledning L (strømskinne) forbundet med plusspolen på * To a wire L (power rail) connected with the positive coil on
en likestrømkilde i form av et batteri Q er der koblet et stort antall koblingskontakter som skal testes, og hvorav bare to, K, a direct current source in the form of a battery Q is connected there a large number of switch contacts to be tested, and of which only two, K,
og K^ i er vist tilkoblet med sin ene kontakt. Den respektive an-nen kontakt er forbundet med inngangen til en såkalt koblingsregulator (dvs . en strømregulator som arbeider etter prinsippet koblinas- and K^ i is shown connected with its one contact. The respective other contact is connected to the input of a so-called switching regulator (i.e. a current regulator that works according to the principle of coupling
styrt strømforsyning) SE^ resp. SE2, hvis utgang B er forbundet med ledningen L. I strømregulatoren SE.^ resp. SE,,, er inngangen A satt i forbindelse med utgangen B via en serie-kobling av en drossel Dr med en diode Di. Klemmene C, D på hver strøm-regulator SE^, SE2# etc. er koblet til minuspolen på batteriet B og via en halvlederbryter U til forbindelsen mellom drosselen Dr og dioden Di. Halvlederbryteren U taktes intermitterende av en regulator R med innført ønskeverdi og med en måleverdi for strøm-men tilført fra utgangen B. controlled power supply) SE^ resp. SE2, whose output B is connected to wire L. In the current regulator SE.^ resp. SE,,, the input A is connected to the output B via a series connection of a choke Dr with a diode Di. The terminals C, D of each current regulator SE^, SE2# etc. are connected to the minus pole of the battery B and via a semiconductor switch U to the connection between the choke Dr and the diode Di. The semi-conductor switch U is clocked intermittently by a regulator R with an entered desired value and with a measured value for current supplied from the output B.
Istedenfor den beskrevne form for strømregulator kan der også anvendes andre i og for seg kjente strømregulatorer, for-trinnsvis slike som endrer sin utgangsspenning i forhold til sin inngangsspenning. Instead of the described form of current regulator, other current regulators known in and of themselves can also be used, preferably those which change their output voltage in relation to their input voltage.
Da bare en brøkdel av den effekt som føres over koblingskontaktene, kan omsettes til varme i strømregulatorene, og den overveiende andel av effekten blir levert tilbake til ledningen L, kan strømregulatorene plasseres etter hverandre i stort antall og da drives betryggende uten særskilte kostbare kjøle-anordninger. Since only a fraction of the power carried over the switching contacts can be converted into heat in the current regulators, and the predominant part of the power is delivered back to the line L, the current regulators can be placed one after the other in large numbers and then operated reliably without special, expensive cooling devices .
Således kan strømmen ved utgangen fra koblingsregulatoren også føres til en særskilt strømkrets, f.eks. matestrømkretsen for ikke viste styreelementer, måleinstrumenter el.l., hvis ledningen L er avbrutt mellom utgangen og inngangen til koblingskontakten . Thus, the current at the output of the switching regulator can also be fed to a separate circuit, e.g. the supply current circuit for control elements not shown, measuring instruments etc., if the line L is interrupted between the output and the input of the coupling contact.
