Description
Lysbue-slukkekammer for brytere. Arc extinguishing chamber for switches.
Det er tidligere kjent plater av mag-netisk material for av-ioniserings-platesett i lysbue-slukkekammere hvor hver plate utgjøres av et kvadratisk blikk av et slikt material brettet sammen til en dyp U. There are previously known plates of magnetic material for de-ionization plate sets in arc extinguishing chambers where each plate consists of a square sheet of such material folded into a deep U.
Et av-ioniseringssett er bygget opp av en samling av slike plater anordnet lodd-rett på hovedretningen for lysbuen med nedsatt avstand mellom to parallelle nabo-plater. A de-ionization set is made up of a collection of such plates arranged perpendicular to the main direction of the arc with a reduced distance between two parallel neighboring plates.
Ved hjelp av denne anordning oppnås to fordelaktige resultater: With the help of this device, two advantageous results are achieved:
Lysbue-delene blir korte. The arc sections will be short.
Det anordnes rom som ikke passeres av lysbuen for bortføring av varmgass som frembringes ved dannelsen og utviklingen av lysbuen. Rooms are arranged that are not passed by the arc for the removal of hot gas produced by the formation and development of the arc.
Foreliggende oppfinnelse går dels ut på andre enkle konstruktive utformninger av platene som gjør det mulig å oppnå de samme resultater, og dels å forsterke kjø-lingen av de varme gasser som føres bort. The present invention is partly based on other simple constructive designs of the plates which make it possible to achieve the same results, and partly to enhance the cooling of the hot gases which are carried away.
Oppfinnelsen angår således lysbue-slukkekammere av den art hvor lysbuen beveges elektrodynamisk og elektromagnetisk i en forut bestemt retning, med et sett magnetiske av-ioniseringsplater som er anordnet i bevegelsesretningen for lysbuen, parallelt med hverandre eller i vifteform og som strekker seg fra den ene sidevegg til den annen i kammeret, og det særegne består i at platene parvis er forbundet elektrisk i det langsgående område langs veggene i kammeret utenfor det område hvor lysbuen dannes, slik at det fremkommer platepar som ligger nær hverandre og er isolert fra hverandre, idet rom mellom platene i hvert platepar danner gass-avtrekkanaler og rom mellom to naboplatepar danner lysbuekanaler, hvor de lysbuedeler kan bevege seg som fremkommer ved oppdelingen av den lysbue som frembringes ved at bryterkontaktene skilles fra hverandre. The invention thus relates to arc extinguishing chambers of the kind where the arc is moved electrodynamically and electromagnetically in a predetermined direction, with a set of magnetic de-ionization plates which are arranged in the direction of movement of the arc, parallel to each other or in the form of a fan and which extend from one side wall to the other in the chamber, and the peculiarity is that the plates are electrically connected in pairs in the longitudinal area along the walls of the chamber outside the area where the arc is formed, so that pairs of plates appear that lie close to each other and are isolated from each other, as spaces between the plates in each pair of plates form gas extraction channels and spaces between two pairs of neighboring plates form arc channels, where the arc parts can move which arise from the division of the arc produced by separating the switch contacts from each other.
Oppfinnelsen går videre ut på at hvert platepar består av to par plater som er bøyet mot hverandre langs minst en av sine sidekanter i lysbueplanet, slik at de forbindes mekanisk og elektrisk langs denne kant. The invention further involves that each pair of plates consists of two pairs of plates which are bent towards each other along at least one of their side edges in the plane of the arc, so that they are connected mechanically and electrically along this edge.
Videre går oppfinnelsen ut på at hvert platepar består av to plater som er forbundet med hverandre ved hjelp av ett eller flere elektrisk ledende mellomstykker som er anordnet nær kantene av platene. Furthermore, the invention is based on each pair of plates consisting of two plates which are connected to each other by means of one or more electrically conductive spacers which are arranged near the edges of the plates.
Endelig går oppfinnelsen ut på at det mellom platene i plateparet og parallelt med disse er anordnet en tredje plate som virker som gasskjøler. Finally, the invention involves a third plate being arranged between the plates in the pair of plates and parallel to them, which acts as a gas cooler.
Andre trekk ved oppfinnelsen vil bli beskrevet nedenfor under henvisning til vedføyde tegninger som viser noen utførel-seseksempler på gjenstanden for oppfinnelsen. Fig. 1, 3, 5 og 6 viser i grunnriss et parti av lysbue-slukkekammeret for brytere, med fire utførelser av platen i hen-hold til oppfinnelsen. For enkelthets skyld er det i hver figur bare vist to plater i av-ioniseringssettet. Fig. 2 og 4 viser perspektivriss av en Other features of the invention will be described below with reference to the attached drawings which show some exemplary embodiments of the object of the invention. Figs 1, 3, 5 and 6 show in plan a part of the arc extinguishing chamber for switches, with four designs of the plate according to the invention. For simplicity, only two plates in the deionization set are shown in each figure. Fig. 2 and 4 show a perspective view of one
plate tilsvarende fig. 1, henhv. fig. 3. plate corresponding to fig. 1, respectively fig. 3.
Som vist i fig. 1 består kammeret av to skall 10 som er lagt sammen langs to forbindelseslinjer 11. De langvegger som står mot hverandre i dette kammer har spor 12 for anbringelse av plater. As shown in fig. 1, the chamber consists of two shells 10 which are joined together along two connecting lines 11. The long walls facing each other in this chamber have grooves 12 for placing plates.
Hver av-ioniseringsplate består av to plane blikk 1 som er bøyet sammen ved 2 langs kantene slik at de berører hverandre langs hele lengden av kantene 3 slik at det dannes elektrisk kontakt. Hvert blikk har form av en bred grunn renne. Each de-ionization plate consists of two flat sheets 1 which are bent together at 2 along the edges so that they touch each other along the entire length of the edges 3 so that electrical contact is formed. Each look has the shape of a wide shallow gutter.
Det kan benyttes mange varianter av denne anordning: sammenbøyningsvin-kelen kan være mere eller mindre lik 90°, ett av blikkene 1 kan være plant uten bøy-ning fra kant til kant, ett eller begge blikk kan være bøyet slik at hver plate får om-trent U-form med en festehale i sporet i kammeret. Many variants of this device can be used: the bending angle can be more or less equal to 90°, one of the sheets 1 can be flat without bending from edge to edge, one or both sheets can be bent so that each plate gets about -trained U-shape with an attachment tail in the slot in the chamber.
Som vist i fig. 3, er sporene 12 utvidet slik at det kan anbringes avioniserings-plater som hver består av to plane og parallelle blikk 4 som holdes i avstand fra hverandre ved hjelp av ledende mellomstykker 5. Disse mellomstykker er anbragt i avstand fra det midtre langsgående plan for kammeret. As shown in fig. 3, the grooves 12 are widened so that deionization plates can be placed, each of which consists of two flat and parallel sheets 4 that are kept at a distance from each other by means of conducting spacers 5. These spacers are placed at a distance from the central longitudinal plane of the chamber .
Disse mellomstykker kan strekke seg over hele høyden av platene eller bare over en del av denne eller utgjøres av en rekke små staver som ligger i avstand fra hverandre langs hele høyden av platene. Mel-lomstykkene kan også alle være anbragt på samme side av det langsgående midt-plan for kammeret, eller de kan ligge på hver sin side av dette plan fra en plate til neste. Hva platene angår, kan de være festet i et eneste spor, idet alle sporene ligger i samme kammer-vegg, eller av-vekslende på den ene eller den annen vegg fra plate til plate. These intermediate pieces can extend over the entire height of the plates or only over a part thereof or consist of a number of small rods which are spaced apart along the entire height of the plates. The intermediate pieces can also all be placed on the same side of the longitudinal middle plane of the chamber, or they can lie on separate sides of this plane from one plate to the next. As far as the plates are concerned, they can be fixed in a single groove, as all the grooves lie in the same chamber wall, or alternately on one or the other wall from plate to plate.
I det tilfelle hvor dybden av kammeret er så stor at rommene for bortføring av gass blir for brede, kan det anbringes ekstra kjølere inne i rommene for derved å opprettholde en tilstrekkelig kjølevirk-ning på gassen. In the case where the depth of the chamber is so great that the spaces for the removal of gas become too wide, extra coolers can be placed inside the spaces to thereby maintain a sufficient cooling effect on the gas.
Som vist i fig. 5, kan det således anbringes en kjøleplate 6 mellom de to blikk 1 som er bøyet sammen og vist i fig. 1. Som vist i fig. 6 er det også mulig å gå ut fra ett eneste blikk som ombrettes to ganger parallelt med seg selv slik at det fremkommer både en avioniseringsplate og inne i denne et kjøleblikk 7. As shown in fig. 5, a cooling plate 6 can thus be placed between the two sheets 1 which are bent together and shown in fig. 1. As shown in fig. 6, it is also possible to proceed from a single sheet which is ombrétted twice parallel to itself so that both an ionization plate and inside this a cooling sheet 7 appear.
Det kan uten vanskelighet istand-bringes andre varianter for utførelse av denne grunntanke, alt etter utførelsen og anbringelsen av av-ioniseringsplatene, slik som det er beskrevet ovenfor. Other variants for carrying out this basic idea can be devised without difficulty, depending on the design and placement of the de-ionization plates, as described above.
Det skal bemerkes at andre kjente forholdsregler, f. eks. V-kanter, innsnitt, isolerende innlegg o.s.v. kan tilpasses de av-ioniseringsplater som er beskrevet eller også gasskjøleplatene. It should be noted that other known precautions, e.g. V-edges, incisions, insulating inserts, etc. can be adapted to the de-ionization plates described or also to the gas cooling plates.
