Description
Foreliggende oppfinnelse angår en koblingsanorei-The present invention relates to a coupling anorei-
ning til aktivisering av et bistabilt relé som kobler en vekselstrbmkrets, ved hvilket relé energiseringsstrbmmen på-virker reléspolen ved korttidig lukking av et koblingselement. ning for activating a bistable relay which connects an alternating current circuit, in which relay the energizing current acts on the relay coil upon short-term closing of a switching element.
Bistabile reléer blir vanligvis betjent ved en kort tilkobling til nettvekselspenning. Herved blir ankeret Bistable relays are usually operated by a short connection to mains AC voltage. This becomes the anchor
til et magnetsystem beveget som bringer en kontaktbro i en annen stilling (se f.eks. DE-OS 20 50 134). to a magnetic system moved which brings a contact bridge into a different position (see e.g. DE-OS 20 50 134).
Koblingstidspunktet, henfort til sinuskurven tilThe switching time, referred to the sine curve of
den spenningen som skal kobles, er herved ikke definert. Den ligger et eller annet sted på spenningskurven. the voltage to be connected is not defined here. It lies somewhere on the voltage curve.
Det fins også bistabile relé, som for den respek-There are also bistable relays, which for the respective
tive koblingstilstand har et elektronisk lager. Med det er rett nok en forespbrring av spenningskurven og derved også tive switching state has an electronic stock. With that, there is quite a request for the voltage curve and thereby also
et definert koblingstidspunkt mulig. Imidlertid blir bygg-elementet svært komplisert. For en minimal kontaktbelast- a defined connection time possible. However, the building element becomes very complicated. For a minimal contact load-
ning skulle koblingstidspunktet ligge nær nullgjennomgangen. ning, the switching time should be close to the zero crossing.
Oppgaven til foreliggende oppfinnelse er med sværtThe task of the present invention is very difficult
få byggelementer å muliggjbre en lukking og åpning av veksel-strbmkretsen i. nærheten av området til nullgjennomgangen til spenningen.. get building elements to enable a closing and opening of the alternating current circuit in the vicinity of the area of the zero crossing of the voltage..
Oppgaven blir ifblge oppfinnelsen derved lost atAccording to the invention, the task is thereby lost
i en seriekobling med reléspolen og koblingselementet er anordnet en formotstand hvorved energiseringsverdiene til reléspolen på bevegelsesmekanismen til det bistabile reléet er således avstemmbart at åpningen til relékontaktene folger 20° til 10° elektrisk for nullgjennomgangen til vekselspenningen og lukker relékontaktene inntil. 20° elektrisk etter nullgjennomgangen til vekselspenningen. in a series connection with the relay coil and the connecting element, a pre-resistor is arranged whereby the energization values of the relay coil on the movement mechanism of the bistable relay can be tuned in such a way that the opening of the relay contacts follows 20° to 10° electrically for the zero crossing of the alternating voltage and closes the relay contacts. 20° electrical after the zero crossing of the alternating voltage.
I en ytterligere utfdrelse av oppfinnelsen er f or-motstanden oppdelt i en motstand og en kaldleder. In a further development of the invention, the front resistor is divided into a resistor and a cold conductor.
Videre sorger oppfinnelsen for at det er anordnetFurthermore, the invention ensures that it is arranged
en frilbpsdiode parallelt til reléspolen.a frilbps diode in parallel with the relay coil.
I en annen utfbrelse av oppfinnelsen blir<:>en tyristor benyttet som koblingselement for energiseringsstrbm-kretsen. In another embodiment of the invention, a thyristor is used as a switching element for the energizing power circuit.
Anordningen ifblge oppfinnelsen skal bli nærmere forklart ved hjelp av tegningene på to utfbrelseseksempler. Fig. 1 viser en aktiveringskrets for et bistabilt relé med formotstand, frilbpdiode og med mekanisk taste. Fig. 2.viser en aktiveringskobling for et bistabilt relé med en elektronisk bryter. Fig. 3 viser et grafisk forlop til forlbpene ifblge The device according to the invention will be explained in more detail with the help of the drawings of two examples. Fig. 1 shows an activation circuit for a bistable relay with resistor, free-flow diode and mechanical key. Fig. 2 shows an activation circuit for a bistable relay with an electronic switch. Fig. 3 shows a graphical sequence of the processes according to
koblingsanordningene på fig. log 2.the coupling devices in fig. log 2.
Ifblge fig. 1 flyter i den positive halvbblgenAccording to fig. 1 flows in the positive half-circle
fra fase pH iiber den mekaniske taste 1 og over formotstanden 2 en strbm ifblge den drivende sinusformede nettspenning gjennom reléspolen til nullederen. from phase pH through the mechanical key 1 and across the resistor 2 a current according to the driving sinusoidal mains voltage through the relay coil to the neutral conductor.
Under hensyntagen til det mekaniske bevegelsesfor-lbpet blir tiltrekningsstrbmmen nådd ved en utvalgt dimen-sjonering av formotstanden til et tidspunkt da lukkingen til relékontakten 4 skjer inntil 20° elektrisk etter nullgjennomgangen og åpningen til relékontakten 4 20° til 10° elektrisk for nullgjennomgangen. Taking into account the mechanical movement process, the attraction current is reached by a selected dimensioning of the resistance to a time when the closing of the relay contact 4 takes place up to 20° electrically after the zero crossing and the opening of the relay contact 4 20° to 10° electrically before the zero crossing.
Til termisk beskyttelse av reléspolen 3 som formotstanden 2, spesielt ved forekomst av forstyrrelse i tasten, er det hensiktsmessig å oppdele formotstanden 2 i en motstand 2a og en kaldleder 2b. Derved blir strbmmen begrenset etter et bestemt tidspunkt til en svært liten verdi hvorved varmeutviklingen blir svært liten. For thermal protection of the relay coil 3 as the pre-resistor 2, especially in the event of disturbance in the key, it is appropriate to divide the pre-resistor 2 into a resistor 2a and a cold conductor 2b. Thereby, the current is limited after a certain point in time to a very small value, whereby the heat generation becomes very small.
Under den negative halvbblgen overtar en til reléet parallellkoblet diode 5 strbmmen likeså frilbpsstrbmmen, hvorved reléankeret blir sikkert holdt og således oppstår ingen brumstby. Ved denne forholdsregelen kan kompliserte kort-slutningsringer bortfalle. During the negative half-wave, a diode 5 connected in parallel to the relay takes over the current as well as the free-flow current, whereby the relay armature is securely held and thus no hum occurs. With this precaution, complicated short-circuit rings can be dispensed with.
I utfbrelseseksemplet ifblge fig. 2 hersker de samme betingelsene som i fig. 1, imidlertid er den mekaniske tasten 1 In the embodiment according to fig. 2 the same conditions as in fig. 1, however, the mechanical key is 1
erstattet av en tyristor 6. Denne utformingen tillater en replaced by a thyristor 6. This design allows a
bryter med ekstremt små styrestrbmmer i porten 6a.switches with extremely small control currents in port 6a.
Av den grafiske fremstillingen på fig. 3 fremgår det at reléspolestrommen stiger i avhengighet av formot- " From the graphic presentation on fig. 3, it appears that the relay coil current rises in dependence on the expected
standen.' Når tilslagsenergiseringen til reléet er nådd, be<-gynner det mekaniske bevegelsesforlopet. Dette er for om-, koblingsforholdet alltid likt, dvs. at tiden fra nådd til-slagsenergisering til åpning av kontakten hhv. lukking av kontakten er likeledesialltid lik. the stand.' When the trigger energization of the relay is reached, the mechanical movement sequence begins. This is for the switching ratio always the same, i.e. that the time from reaching impact energization to opening of the contact or closing the contact is also always the same.
Ved hjelp av denne koblingsanordningen er det altså mulig av kombinasjonen mekanisk bevegelsesforlbp, energi-seringsverdi til reléspolen og formotstanden å oppnå defi-nerte koblingspunkt. Derved blir oppnådd svært liten til-sveising av kontaktene, liten kontaktslitasje og få for-styrrelser. With the help of this switching device, it is thus possible to achieve defined switching points from the combination of mechanical movement progress, energizing value of the relay coil and the resistance. This results in very little welding of the contacts, little contact wear and few disturbances.
