Opfindelsen angår et kontaktsystem med en faststående og en bevægelig, hver med et permanent kontaktområde udstyret kontaktdel, hvoraf den ene er knivformet med en lysbueafrivningskant, og hvor den anden har et med lysbueafrivningskanten samvirkende lysbueområde, som i kon-5 taktsystemets lukkede tilstand ligger over en i den knivformede del anbragt åbning, hvor bevægelsesretningen for den bevægelige kontaktdel forløber på tværs af åbningen og af strømtilførselsretningen for den faststående kontaktdel.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a contact system having a fixed and movable contact member each equipped with a permanent contact area, one of which is knife-shaped with an arc tear-off edge, and the other has an arc region interacting with the arc tear edge, which is in a closed state of the contact system. arranged in the knife-shaped portion, wherein the direction of movement of the movable contact portion extends across the opening and of the direction of supply of the fixed contact portion.
Ved et kendt system af den ovennævnte art (DE-Offentliggørelses-10 skrift 32.23.654) er der ganske vist allerede opnået en relativ god adskillelse af lysbuestedet og det kontaktgivende sted i kontaktsystemet. Det er ved trykkontakter kendt, at anvende slidser til forbedring af lysbueforløbet på den faststående kontaktdel (GB-patentskrift 11 21 012).Admittedly, in a known system of the above-mentioned type (DE-Publication 10, 32.23.654), a relatively good separation of the arc point and the contact point in the contact system has already been achieved. Pressure contacts are known to use slots to improve the arc flow on the fixed contact member (GB patent 11 21 012).
15 Til grund for den foreliggende opfindelse ligger den opgave også at forbedre driften af lysbuen efter dennes opståen. Dette opnås på enkel måde ved, at åbningen i åbningsretningen for kontaktsystemet uden for kontaktområdet løber ud i en slidse, som deler den knivformede kontaktdel. Herved fremkommer der en strømsløjfe, som bevirker en forrin-20 gelse af lysbuestandtiden som følge af en forlængelse af lysbuesøjlen.The object of the present invention is also to improve the operation of the arc after its occurrence. This is accomplished in a simple way by the opening in the opening direction of the contact system outside the contact area extending into a slot dividing the knife-shaped contact part. This results in a current loop which causes a reduction of the arc state time as a result of an extension of the arc column.
Desuden aflastes det permanente kontaktsted fuldstændigt fra lysbuevirkningerne. Hvis slidsen forløber i en mod åbningsretningen hældende og mod afbryderkammervæggen pegende retning, forkortes lysbuestandtiden yderligere som følge af berøring af lysbuen med afbryderkammervæggen.In addition, the permanent contact point is completely relieved from the arc effects. If the slot proceeds in a direction inclined towards the opening direction and towards the switch chamber wall, the arc state time is further shortened as a result of contact of the arc with the switch chamber wall.
25 Det er fordelagtigt, hvis slidsen er anbragt i den faststående kontaktdel, for at sikre en bestemt tilknytning til afbryderkammervæggen. Som følge af slidsens hældning danner der sig ved slidsens udtrædningssted fra fladdelen et lysbuehorn, som er rettet mod afbryderkammervæggen.It is advantageous if the slot is disposed in the fixed contact portion to ensure a certain connection to the switch chamber wall. Due to the inclination of the slit, at the point of exit of the slit, an arc horn is formed which is directed towards the switch chamber wall.
Et udførelseseksempel ifølge opfindelsen beskrives ved hjælp af 30 tegningen.An embodiment of the invention is described by means of the drawing.
På tegningen er den faststående kontaktdel 1 forbundet på ikke nærmere vist måde til afbryderkammervæggen 2. Den faststående kontaktdel er udformet som en kontaktkniv af et stykke fladblik, og samarbejder med den bevægelige kontaktdel 3. Den bevægelige kontaktdel kan være 35 udformet i form af en kontaktrulle - således som dette er vist i DE-In the drawing, the fixed contact part 1 is connected in a not shown manner to the switch chamber wall 2. The fixed contact part is formed as a contact knife of a piece of flat plate and cooperates with the movable contact part 3. The movable contact part can be formed in the form of a contact roller - as shown in DE-

Offentliggørelsesskrift 32.23.654 - og udgør en del af en sikringsafbryder. Den faststående kontaktdel har en lysbueafrivningskant 4, som står frem i forhold til kanten 5 i åbningsretningen. Den egentlige kontaktgivende del i den faststående kontaktdel 1 er betegnet med 6. Den .5 ligger stødende op til åbningen 7, i hvilken den til lysbueafrivningskanten 4 hørende lysbuedel 8 på den bevægelige kontaktdel -3 i lukket tilstand for kontaktsystemet rager ind. Herunder kommer den for den permanente kontakt ansvarlige del 9 på den bevægelige kontaktdel 3 i berøring med den kontaktgivende del 6 på den faststående kontaktdel 1.Disclosure letter 32.23.654 - and forms part of a circuit breaker. The fixed contact member has an arc tear-off edge 4, which projects relative to the edge 5 in the opening direction. The actual contacting part of the fixed contact part 1 is denoted by 6. The .5 is adjacent to the opening 7, in which the arc part 8 of the movable contact part 3 of the movable contact part -3 in the closed state of the contact system protrudes. Below, the part 9 responsible for the permanent contact on the movable contact part 3 comes into contact with the contacting part 6 on the fixed contact part 1.
10 Åbningen 7 går i åbningsretningen for kontaktsystemet over i en slidse.10 The opening 7 goes into a slot in the opening direction of the contact system.
Den hælder i forhold til åbningsretningen i retning mod afbryderkammer-væggen 2, således at den danner et lysbuehorn 11. Lysbuehornet 11 er forskudt i forhold til enden på den bevægelige kontaktdel 3 i retning mod afbryderkammervæggen 2, dvs. lysbuen 12 kan forlænges efter dens 15 opståen. For dette er især den med pilen 13 antydede strømsløjfe ansvarlig, der omkring lysbuen har modsat rettede strømninger, således at lysbuen drives i retning mod afbryderkammervæggen 2 og forlænges. Ved dette lysbueforløb er der intet, som ændrer sig, når der på begge sider af den faststående kontaktdel, fx. i form af ruller, anbringes bevæge-20 lige kontaktdele 3. Der kan således praktisk taget uden yderligere omkostninger opnås en sikker adskillelse mellem permanent- og afbrændingskontaktstedet ved hurtig lysbueslukning.It inclines relative to the opening direction toward the switch chamber wall 2 to form an arc 11. The arc horn 11 is offset relative to the end of the movable contact portion 3 toward the switch chamber wall 2, i. the arc 12 may be extended after its occurrence 15. For this, in particular, the current loop indicated by the arrow 13 is responsible, which has opposite currents around the arc, so that the arc is driven in the direction towards the switching chamber wall 2 and extended. In this arc, there is nothing that changes when on both sides of the fixed contact part, e.g. in the form of rollers, movable contact portions 3 are placed. Thus, at virtually no additional cost, a secure separation between the permanent and firing contact site can be achieved by rapid arc closure.
