Opfindelsen angår en fejlstrøms- og ledningsbeskyttelsesafbryder med afbryder for en O-leder, i hvilken de bevægelige afbryderbroer af den i én husdel anbragte lednings-5 beskyttelsesafbryder er sammenkoblet med den bevægelige kontaktarm af den i en anden husdel anbragte afbryder for O-lederen ved hjælp af en i en husmellemvæg ført glider, og tager udgangspunkt i europæisk offentliggørelsesskrift nr. 149.441.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a fault current and wire protection switch having a switch for an O conductor in which the movable switch bridges of the conductor protection switch located in one housing part are coupled to the movable contact arm of the switch for the O conductor arranged in another housing part. of a sliding led into a wall partition, and is based on European Publication No. 149,441.
10 Det er kendt at forbinde flere ledningsbeskyttelsesafbrydere ved overvågning af flerfaseledninger indbyrdes mekanisk ved hjælp af ud af afbryderhusene ragende funktionsknaster, hvor udløsermekanismen også er indbyrdes forbundet. Udløses mindst én af ledningsbeskyttelses-15 afbryderne på grund af påvirkning fra dens magnetudløser eller dens bimetaludløser, åbnes også de andre ledningsbeskyttelsesafbrydere. Idet det kun er yderledningerne, der skal overvåges, er det ikke nødvendigt at udstyre 0-lederen med en komplet ledningsbeskyttelsesafbryder med 20 mekanisk konstruktion, magnetudløser og bimetaludløser.10 It is known to connect multiple wiring protection switches by monitoring multi-phase wires mechanically by means of function keys projecting out of the switch housings, the trigger mechanism being also interconnected. If at least one of the conductor protection switches is triggered due to the influence of its magnetic trigger or its bimetal trigger, the other conductor protection switches are also opened. As only the outer wires need to be monitored, it is not necessary to equip the 0 conductor with a complete wire protection switch with 20 mechanical construction, magnetic release and bimetal release.
Det har allerede været foreslået at sammenkoble kontakt-apparatet i en afbryder for en O-leder mekanisk med kontaktapparatet i ledningsbeskyttelsesafbryderen med mindst én yderledning.It has already been proposed to mechanically couple the switch in an O-conductor switch to the switch in the line protection switch with at least one outer line.
25 En beskyttelsesafbryder med tvangsmæssig afbrydning af alle poler kendes fra det tyske fremlæggelsesskrift nr. 1.563.919. Ved denne kendte beskyttelsesafbryder forbindes et som glider udformet overføringsorgan, der er ført i noter i sidevæggene, med ind til hinanden liggende hus-30 halvdele. En ulempe ved denne kendte beskyttelsesafbryder består i, at aktiveringsdelen (knæledsdelen) i beskyttelsesafbryderen må udføres med en længere aktiveringsglider.25 A protective circuit breaker with forced interruption of all poles is known from German Patent Specification No. 1,563,919. By this known protection switch, a slider-shaped transfer means, which is inserted in notes in the side walls, is connected to adjacent housing halves. A disadvantage of this known protection switch consists in the fact that the actuating part (knee joint part) of the protective switch must be performed with a longer actuator slide.
En ledningsbeskyttelsesafbryder, i hvilken sammenkoblingen 35 af kontrolaggregatet i ledningsbeskyttelsesafbryderen medA wire protection switch in which the coupling 35 of the control assembly of the wire protection switch with

2 afbryderen for O-lederen er mulig uden ændringer i opbygningen af ledningsbeskyttelsesafbryderen, er kendt fra det østrigske patentskrift nr. 378.283. Ved denne kendte 5 beskyttelsesafbryder, der også er kendt fra det europæiske offentliggørelsesskrift nr. 149.441, med afbryder for en O-leder, er de bevægelige afbryderbroer i beskyttelsesafbryderen, ved hjælp af en gennem sidevæggen i huset for beskyttelsesafbryderne ført glider koblet med 10 den bevægelige kontakt for afbryderen for O-lederen. Glideren har mindst én på den bevægelige kontakt for afbryderen for O-lederen angribende knast, og en som stift dannet udkragning, der samtidig er lejebolten for forbindelsen mellem afbryderbroen og aktiveringsorganet.2 The switch for the O-conductor is possible without changes in the structure of the conductor protection switch, is known from the Austrian patent specification 378.283. In this known protection switch, also known from European Publication No. 149,441, with a switch for an O-conductor, the movable switch bridges in the protection switch are slid coupled to the movable switch through the side wall of the housing of the protection switch. switch for the O-conductor switch. The slider has at least one on the movable contact of the switch for the O-conductor engaging cam, and one as a rigidly formed collar, which is simultaneously the bearing bolt for the connection between the switch bridge and the actuator.
15 Opfindelsen har til formål at angive en beskyttelsesafbryder af ovennævnte art, hvor den glider, der udgør koblingen mellem den med bimetalmagnetudløsning og lysbuebeskyttelsesaggregat udstyrede beskyttede afbryderstrækning og den enkle og ubeskyttede afbryderstrækning, 20 afbryder for O-lederen, bruges til andre funktioner i fejlstrømsbeskyttelsen.The invention has for its object to provide a protective circuit breaker of the above-mentioned type in which the slide forming the coupling between the bimetallic magnetic release and arc protection circuit equipped with the simple and unprotected circuit breaker, 20 circuit for the O conductor, is used for other protection in fault current.
Dette formål opnås ifølge opfindelsen ved, at permanent-magnetudløseren i fej lstrømsbeskytteren er tilknyttet en i huset svingbart lejret arm, hvor den ene ende af armen 25 ligger an mod udløserstiften på permanentmagnetudløseren, og den anden ende af armen i afbryderens indkoblede stilling hviler på et fjederbelastet aktiveringsorgan, der har en tap hørende til klinkefladen i ledningsbeskyttelsesafbryderen, og at der på glideren er anbragt en tap, 30 der svinger aktiveringsorganet imod kraften fra dets tilhørende fjeder ved drejning af kontaktarmen på afbry- . deren for O-lederen til dens lukkede stilling i den for et fast indgreb med den til permanentmagnetudløseren hørende løftearm rigtige stilling.This object is achieved according to the invention in that the permanent magnet trigger in the fault current protector is connected to an arm swingably housed in the housing, where one end of the arm 25 abuts the trigger pin of the permanent magnet trigger and the other end of the arm in the switched on position of the switch. a spring loaded actuator having a pin belonging to the latching surface of the conductor protection switch, and a pin 30 mounted on the slider which pivots the actuator against the force of its associated spring by turning the contact arm on the switch. the o-conductor to its closed position in that of a fixed engagement with the position of the permanent magnet release lever proper.

Med afbryderen ifølge opfindelsen opnås en ledningsbeskyttelse og en fejlstrømsbeskyttelse uden at fejl-strømsbeskytteren behøver en særlig mekanisk konstruktion 5 til aktivering af et kontaktaggregat. Derudover udløser holdemagnetudløseren for fejlstrømsbeskyttelsen ved udløsetilfælde, ved hjælp af løftearmen og aktiveringsglideren, umiddelbart den mekaniske konstruktion i ledningsbeskytteren. Ved hjælp af den på glideren anbragte 10 tap tilbagestilles aktiveringsglideren igen på en sådan måde efter sket udløsning gennem den i udkoblingsstillingen gående glider, at den kan komme til at hvile på permanentmagnetudløserens tilhørende løftearm. Man kan derefter med en enkelt indkoblingsknap igen indkoble 15 afbryderen uden at der behøves særlige konstruktioner til at få løftearmen i fejlstrømsbeskytterdelen til at hvile på aktiveringsglideren, da dette efter udløsning følger af sig selv.With the circuit breaker according to the invention, a line protection and a fault current protection are obtained without the fault current protector needing a special mechanical construction 5 for activating a contact assembly. In addition, the hold magnet trigger for the fault current protection in the event of a trigger, by means of the lifting arm and the actuator slide, immediately triggers the mechanical construction of the wire protector. With the aid of the 10 tabs placed on the slide, the actuating slide is reset in such a way that after the triggering has occurred through the slide in the switch-off position that it can rest on the associated lift arm of the permanent magnet trigger. Then, with a single switch-on button, the switch can be switched on again without the need for special structures to cause the lifting arm in the fault current protection part to rest on the actuating slide, as this, after release, follows by itself.
I en udførelsesform ifølge opfindelsen er udløserstiften i 20 permanentmagnetudløseren forsynet med en drejeligt lejret tilbagestiller, der er dannet som en toarmet løftearm, hvor armen på tilbagestilleren, der hører til permanentmagnetudløseren står under påvirkning fra en fortrinsvis hårnåleformet dannet fjeder, der belaster tilbagestilleren 25 på udløserstiften af permanentmagnetudløseren, og hvor den anden arm på tilbagestilleren ved hjælp af en på glideren anbragt tap ved indkoblet stilling er løftet op af udløserstiften på permanentmagnetudløseren. Med denne udførelsesform opnås en yderligere funktion af gliderne, 30 idet tilbagestilleren ved indkobling af beskyttelsesafbryderen ved hjælp af gliderne løftes på en sådan måde, at udløserstifterne på permanentmagnetudløserne kan aktivere klinkeindgrebet. Derved opnås efter sket udløsning og tilbageføring af glideren i den udkoblede stilling en 35 nedtrykning af udløserstiften på permanentmagnetudløseren ved hjælp af den af tilbagestillingsfjederen påvirkede tilbagestiller.In one embodiment of the invention, the trigger pin in the permanent magnet trigger is provided with a pivotally mounted retractor formed as a two-arm lift lever, the arm of the reset associated with the permanent magnet trigger being actuated by a preferably hairpin-shaped spring protector 25 of the permanent magnet trigger, and wherein the second arm of the reset by means of a pin placed on the slide at the engaged position is lifted up by the trigger pin of the permanent magnet trigger. With this embodiment, a further function of the slides is achieved, in that the reset is switched on by means of the slides when the protective switch is switched on in such a way that the trigger pins on the permanent magnet triggers can activate the latch engagement. Thereby, after the release and return of the slider in the disengaged position, a depressing of the trigger pin on the permanent magnet trigger is achieved by means of the reset actuated by the reset spring.

I en praktisk udførelsesform ifølge opfindelsen er en og samme tap anbragt på glideren til på den ene side at dreje aktiveringsorganet og på den anden side at dreje tilbage-5 stilleren, og tappen er anbragt mellem en forlængelse på aktiveringsorganet og en arm af tilbagestilleren. Derved opnås en rumbesparende placering og en enkel konstruktion, idet én bygningsdel opfyldet to opgaver.In a practical embodiment of the invention, one and the same pin is arranged on the slide to rotate the actuator on one side and to turn the reset on the other hand, and the pin is located between an extension on the actuator and an arm of the reset. This provides a space-saving location and a simple construction, with one building part fulfilling two tasks.
Aktiveringsorganet kan også i den udkoblede stilling ligge 10 an mod et anslag, fastgjort i huset, under påvirkning af den tilhørende fjeder. Derved aflastes aksen af aktiveringsorganet, og udsvinget begrænses således, at tilbagebevægelsen for aktiveringsorganet til den med løftearmen hvilende stilling forenkles.The actuator may also, in the disengaged position, abut a stop, secured in the housing, under the influence of the associated spring. Thereby, the axis of the actuator is relieved and the oscillation is limited so that the actuation of the actuator to the position resting with the lift arm is simplified.
15 Opfindelsen angår derudover en fejlstrøms- og ledningsbeskyttelsesafbryder med afbryder for en O-leder, hvor den bevægelige afbryderbro af den i én husdel anbragte ledningsbeskytter er koblet med den bevægelige kontaktarm af den i en anden husdel værende afbryder for O-ledningen ved 20 hjælp af en gennem husmellemvæggen ført glider.The invention further relates to a fault current and wire protection switch with switch for an O-conductor, in which the movable switching bridge of the conductor located in one housing part is coupled to the movable contact arm of the switch for the O-wire in another housing part. a slider passed through the housing intermediate wall.
Opfindelsen har derudover til formål i en beskyttelsesafbryder af den ovennævnte art at udnytte den som glider udformede kobling mellem den med bimetalmagnetudløsning og lysbueudløsningsaggregat udrustede beskyttede afbryder-25 strækning og den enkle ubeskyttede afbryderstrækning (afbryder for O-lederen) til en yderligere funktion i fejlstrømsbeskytteren.The invention furthermore aims to utilize in a protective circuit breaker of the aforementioned kind that the slider formed coupling between the bimetallic magnetic release and arc trigger assembly protected circuit breaker stretch and the simple unprotected circuit breaker (circuit breaker circuit breaker circuit) for further operation.
Dette formål opnås ved at en i og for sig kendt prøvekreds er forsynet med en prøveknap, to prøvekontakter og en 30 prøvekontaktfjeder, hvor én del af prøvekontaktfj ederen ved trykning på prøveknappen ligger an i anlæg mod den til den hørende prøvekontakt, og ved at en anden del af prøvekontaktf j ederen ligger an mod en anden prøvekontakt og ved åbne kontakter løftes væk fra kontakten ved hjælp af glideren.This object is achieved by providing a test circuit per se known with a test button, two test contacts and a test contact spring, where one part of the test contact spring, when pressed on the test button, abuts against the corresponding test contact, and a the second part of the sample contact spring abuts another sample contact and, with open contacts, is lifted away from the contact by the slider.

DK 163616BDK 163616B
Ved hjælp af gliderens funktion ifølge opfindelsen sluttes 5 den i sig selv kendte prøvekreds ved hjælp af en prøve-kontaktfjeder, der berører to prøvekontakter. Samtidig opnås, at kontakten på trods af trykning på prøveknappen kun er sluttet, når beskyttelsesafbryderen og dermed glideren befinder sig i den til indkoblingen svarende 10 stilling. Derved er en beskadigelse af afbryderen udelukket også ved et længere tids tryk på prøveknappen.By means of the function of the slider according to the invention, the test circuit known per se is closed by means of a test contact spring which touches two test contacts. At the same time, despite the push of the test button, the switch is only closed when the protective switch and thus the slider is in the position corresponding to the switch-on. Thus, damage to the circuit breaker is also excluded by prolonged pressing of the test button.
Fra det europæiske offentliggørelsesskrift nr. 0.144.691 kendes en selvafbryder med indikator for kontaktstilling.From European Publication No. 0144,691, a self-timer with contact position indicator is known.
Den kendte kontaktindstillingsindikator er forbundet med 15 den bevægelige kontakt i selvafbryderen.The known switch setting indicator is connected to the movable switch in the self-switch.
Opfindelsen har derudover til formål, ved en fejlstrøms-og ledningsbeskyttelsesafbryder med afbryder for en 0-leder, i hvilken den bevægelige afbryderbro af den i en husdel anbragte ledningsbeskytter, der er koblet med den 20 bevægelige kontaktarm af den i en anden husdel anbragte afbryder for O-lederen ved hjælp af en glider, der går igennem en husmellemvæg, at benytte den som glider udformede kobling mellem den med bimetalmagnetudløsning og lysbueudløsningsaggregat udrustede afskærmede afbryder-25 strækning og den enkle ubeskyttede afbryderstrækning (afbryder for O-lederen) til andre funktioner.The invention further has the object of a fault current and wire protection switch with switch for a 0 conductor, in which the movable switching bridge of the conductor placed in a housing part coupled with the 20 movable contact arm of the switch placed in another housing part for The O-conductor, by means of a slider passing through a housing partition, utilizes the slider-designed coupling between the bimetallic magnet release and the arc-release assembly equipped with shielded switching stretch and the simple unprotected switching stretch (switch for the O-conductor) for other functions.
Ved en yderligere variant ifølge opfindelsen opnås dette . formål ved i den del af huset, der indeholder fejlstrømsbeskytteren, at anbringe en i og for sig kendt afbryder-30 indikator, der drejeligt er lejret i huset, og hvis ene ende er anbragt ved et vindue i huset og hvis anden ende er koblet med glideren til aktivering af afbryderindikatoren .This is achieved by a further variant according to the invention. purpose of placing in the part of the housing containing the fault current protector a switch indicator known per se which is pivotally mounted in the housing, one end of which is arranged at a window in the housing and the other end of which is coupled with the slider for activating the switch indicator.

Den i den viste 25 husdel anbragte afbryderbane 3 udgøres af O-lederen (N-lederen) og indeholder et kontaktaggregat med en bevægelig afbryderbro 6.In a housing 1 is arranged a permanent magnetic trigger 2 which, in the event of a fault current, receives the necessary energy for release from the differential transformer 5, which is passed through both switching paths 3 and 4. The switching path 3 located in the 25 housing part is constituted by the O-conductor (N conductor) and includes a contact assembly with a movable switch bridge 6.
Den bevægelige afbryderbro 6 er ved hjælp af en kobling, udformet som en glider 7, direkte eller indirekte sammen-30 koblet med den ikke viste bevægelige afbryderbro i ledningsbeskyttelsesafbryderen, således at den bevægelige afbryderbro 6 følger bevægelsen i afbryderbroen i ledningsbeskyttelses afbryderen.The movable switch bridge 6 is connected directly or indirectly to the movable switch bridge in the conductor protection switch by means of a coupling 7 formed as a slider 7, so that the movable switch bridge 6 follows the movement of the switch bridge in the conductor protection switch.

8 I huset 1 er anbragt en løftearm 8, der kan svinge om en lejetap 36, hvis ene ende 11 er beregnet til udløserstiften 9 på permanentmagnetudløseren 2. Den anden ende 12 5 af løftearmen har en næseagtig udformning 13, på hvilken der i den indkoblede stilling (fig. 2) hviler en knast 15 på et aktiveringsorgan 14, der i afbryderen er svingbart lejret om en aksel 16. Ved hjælp af påvirkningen mellem næsen 13 og knasten 15 forhindres en svingning af aktive-10 ringsorganet 14 under indvirkning af den dertil hørende udløsefjeder 17. Aktiveringsorganet 14 har en tap 18, der går igennem mellemvæggen mellem de to husdele, og som i udløsningstilfælde påvirker klinkeudløsningen (ikke vist) i ledningsbeskyttelsesafbryderen, således at dennes udlø-15 sermekanisme starter.8 In the housing 1 is arranged a lifting arm 8 which can pivot about a bearing pin 36, one end 11 of which is intended for the trigger pin 9 on the permanent magnet trigger 2. The other end 12 5 of the lifting arm has a nose-like configuration 13, in which position (Fig. 2), a cam 15 rests on an actuator 14 pivotally mounted in the switch about a shaft 16. By means of the actuation between the nose 13 and the cam 15, a pivot of the actuator 14 is prevented by the action thereof. associated actuating spring 17. The actuator 14 has a pin 18 which passes through the intermediate wall between the two housing parts and, in the case of triggering, influences the latch release (not shown) in the conduit protection switch so that its triggering mechanism starts.
Som det fremgår af fig. 1, er aktiveringsorganet 14 ved hjælp af en tap 19 på en glider 7, der griber ind i en forlængelse 20 af aktiveringsorganet 14 i udkoblet stilling, drejet imod virkningen fra udløsefjederen 17 til den 20 for indgreb med løftearmen 8 rigtige stilling.As shown in FIG. 1, by means of a pin 19 on a slider 7 engaging in an extension 20 of the actuator 14 in the disengaged position, the actuator 14 is rotated against the action of the trigger spring 17 to the right position for engagement with the lifting arm 8.
Tappen 19 på glideren 7 er derudover tilsluttet en ende af en tilbagefører 21 for permantmagnetudløseren 2, der kan drejes om en lejetap 10. Denne tilbagefører 21 påvirkes af en tilbageførefjeder 22, der trykker på den ende 23 af 25 tilbageføreren 21, der vender mod udløserstiften 9 på permanentmagnetudløseren 2 og får denne til at trykke mod udløserstiften 9, når afbryderen er i udkoblet stilling. I indkoblet stilling svinges tilbagestilleren 21 ved hjælp af tappen 19 på glideren 7 på en sådan måde mod kraften 30 fra tilbageførefjederen 22, at enden 23 på tilbagestilleren 21 ikke ligger an mod udløserstiften 9 på permament-magnetudløseren 2. I den i fig. 2 viste indstilling fastholdes dog armen 8's anlæg mod udløserstiften 9 på permanentmagnetudløseren 2 ved hjælp af den tilhørende, i 35 fig. 3 viste holdefjeder 24.In addition, the pin 19 of the slider 7 is connected to one end of a recess 21 for the permanent magnet trigger 2 which can be rotated by a bearing pin 10. This return 21 is actuated by a return spring 22 which presses on the end 23 of 25 the return 21 facing the trigger pin. 9 on the permanent magnet trigger 2 and causes it to press the trigger pin 9 when the switch is in the off position. In the switched-on position, the reset 21 is pivoted by the pin 19 of the slide 7 in such a way against the force 30 of the return spring 22 that the end 23 of the reset 21 does not abut the trigger pin 9 of the permanent magnet trigger 2. In the embodiment shown in FIG. 2, however, the abutment of the arm 8 against the trigger pin 9 of the permanent magnet trigger 2 is retained by means of the associated, in FIG. 3 holding springs 24.

I afbryderen ifølge opfindelsen findes derudover en afbryderindikator 26, der kan dreje om en lejetap 25.In addition, in the switch according to the invention there is a switch indicator 26 which can turn a bearing pin 25.
Denne afbryderindikator 26 er udefra synlig gennem et 5 vindue 27, således at der udefra gennem vinduet i den i fig. 1 viste udkoblede stilling ses et grønt farvet felt og ved den i fig. 2 viste indkoblede stilling vises et rødt farvet felt på afbryderindikatoren 26. Afbryderindikatoren 26 flyttes af glideren 7 ved hjælp af en tap 10 28, der griber ind i en i den ene ende åben udsparing 28' på afbryderindikatoren 26 som en tap/udsparings-kobling.This switch indicator 26 is visible from the outside through a window 27, so that from outside through the window of the embodiment shown in FIG. 1 shows a green colored field and at the position shown in FIG. 2, a red colored field is shown on the switch indicator 26. The switch indicator 26 is moved by the slider 7 by means of a pin 10 28 which engages a recess 28 'open at one end of the switch indicator 26 as a tap / cutout switch. .
Det ses, at på grund af denne konstruktion med frem- og tilbagebevægelse af glideren 7 får afbryderindikatoren 26 en frem- og tilbagegående drejning.It will be seen that, due to this reciprocating movement of the slide 7, the switch indicator 26 receives a reciprocating rotation.
15 I den på tegningen viste husdel af FI/LS-afbryderen ifølge opfindelsen, hvori fejlstrømsbeskytteren er anbragt, er også anbragt en prøvekreds. Denne prøvekreds har to prøvekontakter 29 og 39 og en i huset fastholdt, i det væsentlige U-formet bøjet, prøvekontaktfjeder 30. Det ene ben 31 20 af prøvekontaktf jederen 30 kan ved hjælp af en prøveknap 32 bringes i kontakt med prøvekontakten 29. Det andet ben 33 på prøvekontaktf jederen 30 ligger i indkoblingsstillingen (fig. 2), dvs. når begge de bevægelige afbryderbroer på begge afbryderstrækninger er lukket, an mod 25 prøvekontakten 39. Som det ses i fig. 3, er benet 33 på prøvekontaktf jederen 30 anbragt mellem to fastholdningstappe 34 og 35 på glideren 7. Derved løftes benet 33 ved hjælp af fastholdningstappen 35 væk fra prøvekontakten 39, når afbryderen er i udkoblet stilling (fig. 2). Derved 30 udnyttes glideren 7's bevægelse også til at afbryde prøvekredsen, så snart en udløsning sker på en eller anden måde, f.eks. ved tryk på prøveknappen 32. Det udelukkes på denne måde, at afbryderen ved for lang tids lukning af prøvekredsen beskadiges.In the housing portion of the FI / LS circuit breaker according to the invention, in which the fault current protector is arranged, a test circuit is also arranged. This test circuit has two sample contacts 29 and 39 and one, substantially U-shaped, bent contact spring 30. One leg 31 20 of the sample contact spring 30 can be brought into contact with the sample contact 29 by means of a test button 32. pin 33 of the sample contact spring 30 is in the switch-on position (Fig. 2), ie. when both the movable switch bridges on both switch sections are closed, against the test switch 39. As seen in FIG. 3, the leg 33 of the sample contact spring 30 is disposed between two retaining pins 34 and 35 on the slide 7. By this, the leg 33 is lifted by the retaining pin 35 away from the sample contact 39 when the switch is in the disengaged position (Fig. 2). Thereby, the movement of the slide 7 is also utilized to interrupt the test circuit as soon as a triggering occurs in some way, e.g. by pressing the test button 32. In this way, it is excluded that the switch will be damaged by too long a closing of the test circuit.
35 I det følgende beskrives funktionen af FI/LS-afbryderen ifølge opfindelsen.35 The following describes the function of the FI / LS switch according to the invention.

10 Gående ud fra den i fig. 2 viste indkoblede stilling, hvor knasten 15 griber ind under næsen 13 på løftearmen 8, og tilbagestilleren 21 ved hjælp af tappen 19 på glideren 7 5 er løftet fra udløserstiften 9 på permanentmagnetudløseren 2, i hvilken stilling det røde felt på afbryderindikatoren 26 ses gennem vinduet 27, og hvor derudover benet 33 på prøvekontaktfjederen understøttet af fastholdelsestappen 34 ligger an på prøvekontakten 39, udløses afbryderen 10 f.eks. ved betjening af prøveknappen 32. Ved tryk på prøveknappen 32 svinges benet 31 på prøvekontaktf jederen 30 til kontakt med prøvekontakten 29 (fig. 3), således at prøvekredsen lukkes. Derved udløses permanentmagnetudløseren 2, og armen 8 svinges mod kraften af dens holde-15 fjeder 24 omkring lejetappen 36, hvorved knasten 15 på aktiveringsorganet 14 kommer fri af armen 8, og aktiveringsorganet ved påvirkning fra udløsefjederen 17 drejes i den i fig. 3 viste stilling, hvor den ligger an mod et anslag 37 indbygget i huset. Ved hjælp af denne drejning 20 af aktiveringsorganet 14 bringes, ved hjælp af tappen 18 på aktiveringsorganet 14 klinkeforbindelsen i ledningsbeskyttelsesafbryderen til udløsning af afbryderkonstruktionen. Når afbryderkonstruktionen har udløst, ender afbryderen i den i fig. 1 viste udkoblede stilling.10 Starting from the one shown in FIG. 2, the cam 15 engages under the nose 13 of the lifting arm 8 and the reset 21 by means of the pin 19 of the slide 7 5 is lifted from the trigger pin 9 of the permanent magnet trigger 2, in which position the red field of the switch indicator 26 is seen through the window. 27, and in addition where the pin 33 of the sample contact spring supported by the retaining pin 34 abuts on the sample contact 39, the switch 10 is triggered e.g. by operating the sample button 32. By pressing the sample button 32, the leg 31 of the sample contact spring 30 is pivoted to contact the sample contact 29 (Fig. 3) so that the sample circuit is closed. Thereby, the permanent magnet trigger 2 is released and the arm 8 is pivoted against the force of its holding spring 24 around the bearing pin 36, whereby the cam 15 on the actuator 14 is released from the arm 8, and the actuator is actuated by the actuating spring 17 in the FIG. 3 where it abuts against a stop 37 built into the housing. By means of this pivot 20 of the actuator 14, by means of the pin 18 of the actuator 14, the latch is made in the conduit protection switch to release the switch construction. When the switch assembly has tripped, the switch ends in the one shown in FIG. 1.
25 Idet glideren 7 på grund af koblingen med ledningsbeskyttelsesafbryderen bevæger sig opefter, frigøres først tilbagestilleren 21 og kan under påvirkning fra tilbageførefjederen 22 igen tilbagestille permanentmagnetudløseren 2 ved at trykke udløserstiften 9 ned.As the slide 7 moves upwards due to the coupling with the conduit protection switch, the reset 21 is first released and, under the influence of the return spring 22, can again reset the permanent magnet trigger 2 by pressing the trigger pin 9 down.
30 Tappen 9 på glideren 7 får ved sin opadgående bevægelse anslag mod forlængelsen 20 på aktiveringsorganet 14, således at dette under sammentrykning af udløsefjederen 17 svinger til en forberedt stilling for et nyt samarbejde med armen 8, som i mellemtiden under indvirkning fra 35 holdefjederen 24 igen er drejet tilbage.30 The pin 9 of the slider 7, in its upward movement, is struck against the extension 20 of the actuator 14, so that this, during compression of the release spring 17, swings to a prepared position for a new cooperation with the arm 8, which in the meantime, under the influence of the holding spring 24 is turned back.

Derefter løftes benet 33 på prøvekontaktfjederen 30 ved hjælp af fastholdningstappen 35 på glideren 7 bort fra dens tilhørende prøvekontakt 39, således at prøvekredsen 5 på trods af nedtrykning af prøveknappen 32 og anlæg af benet 31 på prøvekontaktf j ederen 30 mod prøvekontakten 29 ikke kan lukkes.Then, by means of the retaining pin 35 of the slide 7, the leg 33 of the sample contact spring 30 is lifted away from its associated sample contact 39, so that, despite depressing the sample button 32 and abutment of the leg 31 on the sample contact spring 30 against the sample contact 29, the sample circuit 5 cannot be closed.
Derefter svinges afbryderindikatoren 26 under påvirkning fra fastholdningstappen 28, således at der gennem vinduet 10 27 nu ses et grønt felt.Then, the switch indicator 26 is pivoted under the influence of the retaining pin 28, so that through the window 10 27 a green field is now visible.
Ved hjælp af betjening af indkoblingsknappen 38 kan afbryderen igen flyttes til den i fig. 2 viste indkoblede stilling.By means of operation of the switch-on button 38, the switch can again be moved to the one shown in FIG. 2.
Med FI/LS-afbryderen ifølge opfindelsen findes også mulig-15 hed for en "friudløsning". Dette er vist i fig. 4. Indkoblingsknappen 38 er endnu ikke helt i sin til den indkoblede stilling svarende placering, og dog er de bevægelige afbryderbroer 6 allerede lukket. Denne stilling indtræder f.eks. ved sammensvejste kontakter. Skønt glideren 7 endnu 20 ikke fuldstændig befinder sig i den til den indkoblede stilling svarende placering, er knasten 15 på aktiveringsorganet 14 i en sådan placering, at den kan udkoble yderlednings af bryder s trækningen. Ligeledes er tilbagestil leren 21 ved hjælp af tappen 19 allerede løftet så meget, 25 at udløserstiften 9 på permanentmagnetudløseren 2 kan svinge armen 8 til et sammenstød mellem armen 8 og aktiveringsglideren 14, dvs. løsning af fastholdelsen mellem næsen 13 og knasten 15.With the FI / LS switch according to the invention there is also the possibility of a "free release". This is shown in FIG. 4. The switch-on button 38 is not yet fully positioned corresponding to the switch-on position, and yet the movable switch bridges 6 are already closed. This position occurs, for example. by welded contacts. Although the slider 7 is not yet fully in the position corresponding to the engaged position, the cam 15 on the actuator 14 is in such a position that it can disengage the outer conduit of the switch pull. Also, by means of the pin 19, the reset 21 has already been lifted so much that the trigger pin 9 of the permanent magnet trigger 2 can pivot the arm 8 into a collision between the arm 8 and the actuating slide 14, ie. loosening the retention between the nose 13 and the cam 15.
I denne stilling kan det røde område på afbryderindikato-30 ren 26 ses udefra gennem vinduet 27 (af hensyn til overskueligheden er afbryderindikatoren 26 ikke vist i fig. 3 og 4).In this position, the red area of the switch indicator 26 can be seen from outside through the window 27 (for reasons of clarity, the switch indicator 26 is not shown in Figures 3 and 4).
