Description

DK 151618 BDK 151618 B

Opfindelsen vedrører en fremgangsmåde til frembringelse af et beskyttet miljø omkring et arbejdsområde, som f.eks. skal holdes fri for urenheder. Fra f.eks. tysk offentliggørelsesskrift 2 624 091, engelsk offentlig-5 gørelsesskrift 2 044 160 og engelsk patentskrift 1 109 365 kendes der beskyttelseskamre dels til brug i forbindelse med et stationært arbejdsområde og dels til anvendelse som transportbeskyttelse f.eks. til giftige filtre.The invention relates to a method of creating a protected environment around a work area, such as should be kept free of impurities. From e.g. German Patent Specification 2 624 091, English Patent Specification 2 044 160 and English Patent 1 109 365 protect chambers partly for use in connection with a stationary work area and partly for use as transport protection e.g. for toxic filters.

Den kendte teknik har den ulempe, at de nævnte sluser 10 har en fast position i beskyttelseskammerets væg, og arbejdsområdets udstrækning er derfor meget begrænset.The prior art has the disadvantage that said locks 10 have a fixed position in the wall of the protective chamber, and therefore the extent of the working area is very limited.

Der eksisterer imidlertid anvendelsesområder, hvor det ville være ønskeligt at have et væsentligt større arbejdsområde, f.eks. ved sammensplejsning af kabler.However, areas of application exist where it would be desirable to have a substantially larger work area, e.g. when connecting cables.

15 Formålet med opfindelsen er at angive en fremgangsmåde til frembringelse af et beskyttet miljø omkring et arbejdsområde, hvis længdeudstrækning er væsentlig større, end det hidtil har kunnet opnås.The object of the invention is to provide a method for creating a protected environment around a working area whose length elongation is substantially greater than has hitherto been achieved.

Dette formål opnås ved, at fremgangsmåden udøves som 20 angivet i krav l's kendetegnende del, som indebærer, at i det mindste den del af beskyttelseskammeret, hvor sluserne eller åbningerne for operatørens arme er anbragt, er forskydelig langs arbejdsområdet. Dette beror således på anvendelsen af et beskyttelseskammer, hvor 25 kammerets endeområder, som fastgøres omkring det aflange emne, anbringes med en indbyrdes afstand, som er mindre end afstanden mellem nævnte endeområder, når beskyttelseskammeret er helt udstrakt.This object is achieved by the method being carried out as defined in the characterizing part of claim 1, which means that at least the part of the protective chamber where the locks or openings for the operator's arms are arranged is slidable along the working area. This is thus due to the use of a protective chamber in which the end regions of the chamber, which are fixed around the elongate blank, are placed at a mutual distance which is less than the distance between said end regions when the protective chamber is fully extended.

Ved at anvende en sammenfoldelig folie, således som 30 det er anført i krav 2, opnås der en meget billig ud førelsesform, så billig at beskyttelseskammeret med fordel kan være beregnet til éngangsanvendelse. SomBy using a collapsible foil, as stated in claim 2, a very inexpensive embodiment is obtained, so inexpensive that the protective chamber can be advantageously intended for single use. As

2 anført i krav 3 kan der på i og for sig kendt måde ledes kontrolleret gas ind i beskyttelseskammeret, hvilket fortrinsvis tilvejebringes på den i krav 4 angivne måde, hvorved overtrykket i kammeret holder folien ud-5 spændt omkring arbejdsområdet.2, as claimed in claim 3, controlled gas can be introduced into the protective chamber in a manner known per se, which is preferably provided in the manner specified in claim 4, whereby the overpressure in the chamber keeps the film 5 stretched around the working area.

Ved at udøve fremgangsmåden ifølge krav 5 kan det opnås, at både beskyttelseskammeret og dets tilhørende emballage kan føres ind over en kabelende ved at afrive de nævnte afrivningsområder af emballagen og føre beskyttel-10 seskammeret og emballagen ind over kablet. Ved at udøve fremgangsmåden som anført i krav 6 kan der foruden de i forbindelse med krav 5 forklarede fordele opnås den særlige fordel, at beskyttelseskammeret er fuldstændig beskyttet af emballagen, selv om nævnte dele er trukket 15 ind over en kabelende. Under selve kabelsplejsningen er der derfor overhovedet ikke behov for at tage hensyn til beskyttelseskammeret, da dette er fuldstændig indesluttet i dets emballage.By practicing the method of claim 5, it can be achieved that both the protective chamber and its associated packaging can be inserted over a cable end by tearing off said tear areas of the packaging and passing the protective chamber and packaging over the cable. By practicing the method as claimed in claim 6, in addition to the advantages explained in connection with claim 5, the special advantage can be obtained that the protective chamber is completely protected by the packaging, even though said parts are retracted over a cable end. Therefore, during the cable splicing itself, there is no need at all to take the protection chamber into account, as this is completely enclosed in its packaging.

Opfindelsen angår endvidere et beskyttelseskammer til 20 udøvelse af fremgangsmåden, hvilket beskyttelseskammer er ejendommeligt ved den i krav 7's kendetegnende del angivne udformning. Dette beskyttelseskammer er specielt beregnet på éngangsbrug og medfører ved udøvelse af fremgangsmåden ifølge krav 1 et beskyttet miljø om-25 kring et langstrakt arbejdsområde. Folien er fortrinsvis gennemsigtig, men kunne også være uigennemsigtig. I sidstnævnte tilfælde vil beskyttelseskammeret være forsynet med en rude eller lignende, således at operatøren kan se arbejdsområdet, jævnfør krav 8. 1The invention further relates to a protective chamber for carrying out the method, said protective chamber being characterized by the design according to the characterizing part of claim 7. This protective chamber is specially intended for single use and, when practicing the method of claim 1, provides a protected environment around an elongated working area. The foil is preferably transparent but could also be opaque. In the latter case, the protective chamber will be provided with a pane or similar, so that the operator can see the working area according to claim 8. 1

Som tidligere nævnt kan beskyttelseskammeret holdes i udspændt stilling som følge af et luftovertryk, men alternativt, eller i kombination hermed, kan der forefindes de i krav 9 nævnte elastiske afstivningsorganer.As previously mentioned, the protective chamber can be held in the tensioned position due to an air overpressure, but alternatively, or in combination therewith, the elastic stiffening means mentioned in claim 9 may be provided.

De i krav 10 nævnte midler til at ventilere beskyttelseskammeret kan f.eks. blot være et indblæsningsrør og et udblæsningsrør, som er beliggende tæt op ad en respektiv af de sammensplejsede kabelender, således 5 at beskyttelseskammerets endeområder omslutter både en kabelende og et af nævnte rør.The means for ventilating the protective chamber as claimed in claim 10 can e.g. merely be a blow-in pipe and a blow-out pipe located close to one of the interlaced cable ends, respectively, such that the end regions of the protective chamber enclose both a cable end and one of said tubes.

Opfindelsen bliver nærmere forklaret i den følgende beskrivelse af nogle udførelsesformer, idet der henvises til tegningen, hvor 10 fig. 1 og 2 viser en første udførelsesform for beskyttelseskammeret ifølge opfindelsen, fig. 3 og 4 viser en anden udførelsesform for beskyttelseskammeret ifølge opfindelsen, medens fig. 5 tjener til at illustrere, hvorledes beskyttelses-15 kammeret kan være pakket sammen i en emballage, i hvilken der på figuren er foretaget et indsnit, medens fig. 6 viser en foretrukken ud førelses form for anbringelse af beskyttelseskammeret omkring arbejdsområdet.The invention will be explained in greater detail in the following description of some embodiments, with reference to the drawing, in which: FIG. 1 and 2 show a first embodiment of the protective chamber according to the invention; 3 and 4 show another embodiment of the protective chamber according to the invention, while FIG. 5 serves to illustrate how the protective chamber may be packed in a package in which a cut is made in the figure, while FIG. 6 shows a preferred embodiment of the positioning of the protective chamber around the working area.

Opfindelsen vil i det følgende blive forklaret i for-20 bindelse med arbejdet ved splejsning af to kabelender.The invention will be explained in the following in connection with the work of splicing two cable ends.

På figurerne er kabelenderne 1, 2 allerede elektrisk sammenkoblede, således at det arbejde, som er relevant for opfindelsen, vedrører retableringen af isolationen omkring splejsningen. 1In the figures, the cable ends 1, 2 are already electrically interconnected, so that the work relevant to the invention relates to the restoration of the insulation around the splice. 1

En velkendt og meget effektiv måde til retablering af kablets isolation går ud på at vikle et tyndt bånd, fortrinsvis af tværbindingsdygtigt polyethylen, mange gange rundt om splejsningen til opbygning af isolationen, som derefter vulkaniseres, således at nævnte bånd smelterA well-known and very effective way of restoring the cable's insulation is to wrap a thin band, preferably of cross-linkable polyethylene, many times around the splice to build the insulation, which is then vulcanized so that said band melts

4 sammen med kablets isolation til en homogen isolation.4 together with the cable insulation for a homogeneous insulation.

Ued højspændingskabler hersker der et meget kraftigt spændingsfelt gennem isolationens og selv de mindste urenheder i isolationen kan give anledning til elek-5 triske feltforstyrrelser, som kan medføre gennemslag i isolationen. Det er derfor uhyre vigtigt, at der ikke kommer fremmedlegemer ind mellem det relativt store antal viklinger af polyethylenbåndet. Specielt de sidstnævnte problemer løses elegant og billigt ved opfindelsen, 10 som derfor vil blive forklaret i forbindelse med en kabelsplejsning.Without high voltage cables, a very strong voltage field prevails through the insulation and even the smallest impurities in the insulation can give rise to electrical field disturbances, which can cause breakthrough in the insulation. It is therefore extremely important that no foreign bodies enter between the relatively large number of coils of the polyethylene tape. In particular, the latter problems are solved elegantly and inexpensively by the invention, 10 which will therefore be explained in connection with a cable splice.

Som tidligere forklaret er kabelenderne 1 og 2 allerede indbyrdes elektrisk sammenkoblede ved en splejsning 3. På fig. 2 er det skematisk vist, hvorledes det nævnte 15 polyethylenbånd 4 vikles omkring splejsningen, og det er i forbindelse med denne opvikling meget vigtigt, at der ikke kommer fremmedlegemer ind mellem polyethylen-lagene. Dette opnås ved at frembringe et i og for sig kendt, beskyttet miljø omkring arbejdsområdet, hvilket 20 i forhold til den kendte teknik imidlertid har den vanskelighed, at arbejdsområdet er langstrakt. På fig.As previously explained, the cable ends 1 and 2 are already electrically interconnected by a splice 3. In FIG. 2, it is shown schematically how the said polyethylene band 4 is wound around the splice, and in connection with this winding it is very important that no foreign bodies enter between the polyethylene layers. This is achieved by creating a known, protected environment around the work area, which, however, has the difficulty of elongating the work area in relation to the prior art. In FIG.

1 er beskyttelseskammeret ifølge opfindelsen vist som en aflang, gennemsigtig folie 5, på hvilker. der er fast-svejset et par adgangssluser 6, 7, gennem hvilke en 25 operatør 8- kan indføre armene. Normalt vil der derved kun opnås et relativt lille arbejdsområde, men ved at hele beskyttelseskammeret ifølge opfindelsen kan forskydes i kablets længderetning, kan det opnås, at operatøren har rigelig bevægelsesfrihed til at lægge poly-30 ethylenbåndet omhyggeligt rundt om splejsningen. Sidstnævnte bevægelighed skyldes ved den viste udførelses-form, at foliekammerets ender 9, 10 er fastgjort på hver sin side af splejsningen med en indbyrdes afstand, som er noget mindre end afstanden mellem nævnte ender 35 i kammerets 5 udstrakte stilliny. Da kammeret 5 er frem-1, the protective chamber according to the invention is shown as an elongated, transparent film 5, on which. a pair of access locks 6, 7 are welded through which an operator 8- can insert the arms. Normally, only a relatively small working area will thereby be obtained, but by allowing the entire protective chamber of the invention to be displaced in the longitudinal direction of the cable, it can be achieved that the operator has ample freedom of movement to carefully place the polyethylene tape around the splice. The latter movement is due to the illustrated embodiment because the ends 9, 10 of the foil chamber are fixed on each side of the splice with a spacing which is somewhat less than the distance between said ends 35 in the extended stillness of the chamber 5. Since the chamber 5 is

DK 151618 BDK 151618 B

5 stillet af tyndt foliemateriale, kan hele kammeret længdeforskydes, således som det fremgår ved sammenligning mellem fig. 1 og 2.5, made of thin foil material, the entire chamber can be longitudinally displaced, as can be seen by comparing FIG. 1 and 2.

Ved en foretrukken udførelsesform holdes foliekammeret 5 i udspændt tilstand som følge af et luftovertryk, som kan tilvejebringes ved, at der ledes luft ind gennem en slange 11, hvor luften ledes ud via en anden slange 12 med et så stort tryktab, at beskyttelseskammeret 5 holdes udspilet. Luften, som ledes ind gennem slangen 10 11, kan være forbehandlet på i og for sig kendt måde, dvs. være filtreret, opvarmet, tørret, helt eller delvist bestå af specielle gasarter, m.v.In a preferred embodiment, the foil chamber 5 is held in a stressed state due to an air overpressure which can be provided by passing air through a hose 11, the air being discharged via another hose 12 with such a large loss of pressure that the protective chamber 5 is kept distended. The air which is passed in through the hose 10 11 can be pretreated in a manner known per se, ie. be filtered, heated, dried, wholly or partly composed of special gases, etc.

Ved en foretrukken udførelsesform er beskyttelseskammerets ender 9, 10 fastgjort til kabelenderne henholdsvis 15 1, 2 f.eks. ved hjælp af en omsnøring 13, 14, som om slutter både en kabelende og en tilhørende luftslange.In a preferred embodiment, the ends 9, 10 of the protective chamber are attached to the cable ends 15, 1, 2, e.g. by means of a strap 13, 14, as if terminating both a cable end and an associated air hose.

Eventuelle utætheder ved de nævnte omsnøringer har ingen betydning, da der er etableret overtryk i beskyttelseskammeret. I denne forbindelse kan det også bemærkes, 20 at beskyttelseskammerets indre volumen er i det væsentlige konstant, uafhængigt af kammerets længdeforskydning således at kammeret på ingen måde komprimeres eller expanderes, men snarere ruller langs kablet.Any leaks from the aforementioned straps do not matter, as overpressure is established in the protective chamber. In this connection, it may also be noted that the internal volume of the protective chamber is substantially constant, independent of the longitudinal displacement of the chamber so that the chamber is in no way compressed or expanded, but rather rolls along the cable.

Som ovenfor nævnt kan beskyttelseskammeret holdes ud-25 spilet ved hjælp af et luftovertryk. Alternativt, eller i kombination hermed, kan der forefindes andre midler til at holde kammeret udspilet, hvilket vil blive forklaret i forbindelse med den på fig. 3 og 4 viste udførelsesform. Ved sidstnævnte udførelsesform er der 30 fortsat tale om en gennemsigtig (alternativt en med rude forsynet) folie, som udgør beskyttelseskammeret.As mentioned above, the protective chamber can be held out by an air overpressure. Alternatively, or in combination therewith, other means for holding the chamber may be provided, which will be explained in connection with the one shown in FIG. 3 and 4. In the latter embodiment, there is still a transparent (alternatively a windowed) film which forms the protective chamber.

Som det fremgår af figurerne omfatter beskyttelseskammeret en tynd elastisk spiral 16, fortrinsvis af plast, således 6As can be seen from the figures, the protective chamber comprises a thin elastic coil 16, preferably of plastic, thus 6

at den let kan klippes over, når beskyttelseskappen fjernes fra den færdige kabelsplejsning. Efter den til fig. 1 og 2 hørende forklaring skulle fig. 3 og 4 herefter tale for sig selv. Det vil endvidere kunne forstås, 5 at beskyttelseskappen ikke behøver at være et ensartet hylster, men at det er tilstrækkeligt, at blot en vis del af beskyttelseskappens ender er eftergivelige på en sådan måde, at kappens ender kan fastgøres omkring arbejdsområdet med en indbyrdes afstand, som er mindre 10 end afstanden mellem nævnte områder i kappens udstrakte tilstand.that it can be easily cut when removing the protective cap from the finished cable splice. According to FIG. 1 and 2, FIG. 3 and 4 then speak for themselves. It will further be appreciated that the protective cap need not be a uniform casing, but that it is sufficient that only a certain portion of the ends of the protective cap be resilient in such a way that the ends of the cap can be secured around the working area at a distance from one another. which is less than the distance between said areas in the extended state of the jacket.

Under henvisning til fig. 5 og 6 vil det nu bliv^ forklaret, hvorledes beskyttelseskappen ifølge opfindelsen med fordel emballeres, således at beskyttelsen mod uren-15 heder sikres, selv om den øvrige del af arbejdet, såsom den mekaniske sammensplejsning af de elektriske ledere, foregår i et urent miljø.Referring to FIG. 5 and 6, it will now be explained how the protective cap according to the invention is advantageously packaged so that the protection against impurities is ensured even though the other part of the work, such as the mechanical splice of the electrical conductors, takes place in an unclean environment. .

Fig. 5 viser en emballage 17, fortrinsvis af plast, der er indrettet til at omslutte beskyttelseskappen 20 hermetisk i en opbevaringstilstand. For bedre at kunne forklare princippet er der foretaget et udsnit i emballagen 17, hvorved det kan ses, at beskyttelseskappen 15 er sammenfoldet som en bælg med en gennemgående aksial passage. I flugt med den aksiale passage har to af em-25 ballagens modstående sider en svækkelseslinie 18, 19, som omkranser hvert sit afrivningsområde. Det vil således kunne forstås, at hvis afrivningsområderne fjernes, kan beskyttelseskappen 15 og den tilhørende emballage 17 føres ind over en kabelende. 1 På fig. 5 og 6 er emballagen fortegnet af hensyn til forklaringen af princippet, hvor fig. 6 skal illustrere en foretrukken fremgangsmåde, hvorefter en første emballageside 20 trækkes igennem beskyttelseskammerets 7FIG. 5 shows a packaging 17, preferably of plastic, which is arranged to enclose the protective cap 20 hermetically in a storage state. In order to better explain the principle, a section has been made in the packaging 17, whereby it can be seen that the protective cap 15 is folded like a bellows with a through axial passage. In flight with the axial passage, two of the opposite sides of the packaging layer have a weakening line 18, 19 which encircles each of its tear area. Thus, it will be appreciated that if the tear areas are removed, the protective cap 15 and the associated packaging 17 can be inserted over a cable end. 1 In FIG. 5 and 6, the packaging is illustrated for the sake of explanation of the principle in which fig. 6 is to illustrate a preferred method, after which a first packaging side 20 is drawn through the protective chamber 7

DK 151618BDK 151618B

aksiale passage og gennem hullet i den modstående emballageside 21, hvorved beskyttelseskammeret 15 helt er indesluttet i en emballage, som nu lader sig skyde ind over en kabelende 22. Derefter kan kabelenden 22 5 sammenkobles elektrisk med en anden kabelende 23, hvorefter retableringen af isolationen skal foretages. Retableringen påbegyndes med, at splejsningsområdet rengøres, og at der ved hjælp af tape eller lignende fastgøres det nødvendige værktøj og materialer for arbejdet om-10 kring splejsningen. Derefter trækkes beskyttelseskammeret og emballagen hen til et rengjort sted i afstand fra splejsningen, hvor emballagen klippes op, hvorefter beskyttelseskammeret kan trækkes hen over splejsningen og fastgøres i enderne, f.eks. som vist ved 13, 14 på 15 fig. 1. Når arbejdet, som kræver det beskyttede miljø, er tilendebragt, klippes foliekammeret op og fjernes fra splejsningen.axial passage and through the hole in the opposite packaging side 21, whereby the protective chamber 15 is completely enclosed in a package which is now slidable over a cable end 22. Thereafter, the cable end 22 5 can be electrically coupled to another cable end 23, after which the restoration of the insulation must be made. The restoration is started by cleaning the splicing area and by using tape or the like to attach the necessary tools and materials for the work around the splicing. Then, the protective chamber and the packaging are pulled to a clean place away from the splice, where the packaging is cut up, after which the protective chamber can be pulled over the splice and secured to the ends, e.g. as shown at 13, 14 in FIG. 1. When the work requiring the protected environment is completed, the foil chamber is cut open and removed from the splice.
