Description
Avslutning og tilkoblingsklemme for oljekabler. Termination and connection clamp for oil cables.
I forbindelse med oljekabler foreligger det problem å skaffe en oljetett avslutning In connection with oil cables, there is a problem of obtaining an oil-tight termination
i forbindelse med en tilkobling til ytre kretser, f. eks. et innendørs ledningsnett, og oppfinnelsen tar sikte på å løse pro-blemet på en enkel og billig måte som samtidig gir full sikkerhet mot lekkasje og muliggjør etterfylling av olje som er gått tapt under montasjen. in connection with a connection to external circuits, e.g. an indoor wiring network, and the invention aims to solve the problem in a simple and cheap way which at the same time provides full security against leakage and enables the refilling of oil that has been lost during assembly.
Avslutningen og tilkobliingsklemmen The termination and connection terminal
ifølge oppfinnelsen er av den art som består av en isolerende hylse, i hvis ene ende kablen er ført inn og fastklemt rundt sin blymantel ved hjelp av en tettende ringpakning som er fastpresset mellom et sete i boringen i hylsens ene ende og endepartiet av en i samme ende av hylsen innskrudd, gjenget nippel som omgir blymantelen, og hvor kablens ende omsluttes av et kammer som i hylsens annen ende er lukket ved en kabelsko som er oljetett innskrudd i hylsen og opptar enden av den avisolerte kabelkjerne; oppfinnelsen ut-merker seg ved at den indre ende av kabelskoen.s utvendig gjengede hylse er konisk og trykker tettende mot et tilsvarende formet sete i boringen, og at der mellom en ytre krave på kabelskoen og/eller nippelen på den ene slide og hylsens ene eller begge endeflater på den annen side, er anordnet en tetning i form av en ringvulst. according to the invention is of the type that consists of an insulating sleeve, at one end of which the cable is inserted and clamped around its lead sheath by means of a sealing ring gasket that is pressed between a seat in the bore at one end of the sleeve and the end part of a in the same end of the sleeve screwed in, threaded nipple that surrounds the lead sheath, and where the end of the cable is enclosed by a chamber that is closed at the other end of the sleeve by a cable shoe that is oil-tight screwed into the sleeve and occupies the end of the stripped cable core; the invention is distinguished by the fact that the inner end of the cable lug's externally threaded sleeve is conical and presses tightly against a correspondingly shaped seat in the bore, and that between an outer collar on the cable lug and/or the nipple on one slide and the sleeve's one or both end surfaces on the other hand, a seal in the form of an annular bead is arranged.
Oppfinnelsen skal forklares under henvisning til tegningen, hvor fig. 1 viser et lengdesnitt av en avslutning med til-sluttet kabelsko og fig. 2 samme avslutning forsynt med en annen videre forbindelses-innretning. The invention will be explained with reference to the drawing, where fig. 1 shows a longitudinal section of a termination with a connected cable lug and fig. 2 same termination provided with another further connection device.
Avslutningen og tilkoblinksklemmen ifølge oppfinnelsen består av en ytre hylse The termination and connection clamp according to the invention consists of an outer sleeve
8 av isolerende materiale, hensiktsmessig 8 of insulating material, appropriate
et hvilketsomhelst egnet materiale som ikke angripes av oljen og som samtidig har en betydelig mekanisk styrke, f. eks. slag-fast plast. Begge hylsens ender er forsynt med innvendige gjenger, idet det nedre parti har en utboring som er større enn det øvre. Inn i den nedre ende er skrudd en nippel 15 som omslutter kabelens blymantel 1 og hvis indre ende 16 er konisk for sammentrykning av en ringpakning 14 som hviler mot et konisk formet sete 16' i hylsen. Niplen har et hode 17 som kan være sekskantet for bruk av skrunøkkel og som likeledes er utført av et isolerende materiale, f. eks. nylon. Pakningen 14 er hensiktsmessig av en myk polyvinylklorid. any suitable material which is not attacked by the oil and which at the same time has considerable mechanical strength, e.g. impact-resistant plastic. Both ends of the sleeve are provided with internal threads, the lower part having a bore that is larger than the upper part. A nipple 15 is screwed into the lower end, which encloses the cable's lead sheath 1 and whose inner end 16 is conical for compressing a ring gasket 14 which rests against a conically shaped seat 16' in the sleeve. The nipple has a head 17 which can be hexagonal for the use of a wrench and which is also made of an insulating material, e.g. nylon. The gasket 14 is suitably made of a soft polyvinyl chloride.
Like innenfor pakningen 14 er blymantelen 1 fjernet for å avdekke et stykke av papirisolasjonen 2 som vil stikke inn i et kammer 11 i hylsen. På den ytre ende av kabelen er også papirisolasjonen fjernet for å avdekke kjernen 3 som er ført inn i en boring 10 som utgjør en direkte fort-settelse av kammeret 11. Just inside the gasket 14, the lead jacket 1 has been removed to reveal a piece of the paper insulation 2 which will stick into a chamber 11 in the sleeve. At the outer end of the cable, the paper insulation has also been removed to reveal the core 3 which is led into a bore 10 which is a direct continuation of the chamber 11.
Fra den annen ende er der i hylsen 8 innskrudd en kabelsko 4, 6, 7, hvis gjengede parti er betegnet med 4 og har et aksi-alt hulrom for innlodding av kjernen 3. Det gjengede parti går over i en sirkulær endeplate 6 som er i ett med kabelskoens tilkoblingsøre 7. For å tilveiebringe tetning mellom den gjengede del 4 og kammeret 11 ender delen 4 i et konisk parti som sam-virker med et tilsvarende formet sete 5 i boringen i hylsen 8. From the other end, a cable lug 4, 6, 7 is screwed into the sleeve 8, whose threaded part is designated 4 and has an axial cavity for soldering the core 3. The threaded part passes into a circular end plate 6 which is in one with the cable shoe's connection ears 7. To provide a seal between the threaded part 4 and the chamber 11, the part 4 ends in a conical part which cooperates with a correspondingly shaped seat 5 in the bore in the sleeve 8.
I tillegg til de to tetninger 14 og 5 er der mellom de ytre kraver 17 og 6 på niplen 15 hhv. kabelskoen 4, 6, 7 på den ene side og hylsens endeflate på den annen i side anordnet tetninger i form av ring-vulster 18 hhv. 9 som vil bli noe deformert under tilskruingen. For å kunne etterfylle olje som måtte være gått tapt under montasjen og for å holde kammeret 11 fylt med olje er der i hylsens sidevegg innskrudd : en tetningsskrue 12 med pakning 13. In addition to the two seals 14 and 5, there are between the outer collars 17 and 6 on the nipple 15 respectively. the cable shoe 4, 6, 7 on one side and the end surface of the sleeve on the other side arranged seals in the form of ring-beads 18 respectively. 9 which will be somewhat deformed during screwing. In order to be able to top up oil that may have been lost during assembly and to keep the chamber 11 filled with oil, a sealing screw 12 with gasket 13 is screwed into the side wall of the sleeve.
Fig. 1 viser det tilfelle at kabelskoens tilkoblingsøre 7 f. eks. skal forbindes med et samleskinnesystem som befinner seg i det rom hvor kabelen er ført frem. Hvis fordelingsrommet eller fordelingstavlen befinner seg på et annet sted i bygningen og man ikke ønsker å føre den kostbare oljekabel gjennom innvendige rom, kan avslutningen foregå på det sted hvor kabelen kommer frem på samme måte som an-gitt ovenfor og forbindes videre med en vanlig innendørs kabel som fører frem til fordeMngsanlegget. I dette tilfelle anvendes den tilkoblingsmåte som fremgår av fig. 2, hvor den eneste forskjell består i at tilkoblingsøret 7 er erstattet med en aksial tapp T som stikker opp fra kraven eller skiven 6. På denne tapp er skrudd en hylse 19 som tilhører en konisk klemhylse, hvis mutter er betegnet med 20. Inn i hylsen er den avisolerte ende av kabelen 21 stuk-ket og fastklemt. For å isolere de strøm-førende deler 6, 19 og 20 er der utenpå disse skjøvet en hylse 22 av isolerende materiale. Dennes øvre ende passer rundt kabelen 21, og dens nedre ende 23 passer utenpå skiven eller kraven 6 og den øvre ende av hylsen 8. Den hviler med en av-sats 24 på oversiden av kraven 6 som vist. Fig. 1 shows the case that the cable shoe's connection ear 7 e.g. must be connected to a busbar system located in the room where the cable is brought forward. If the distribution room or the distribution board is located elsewhere in the building and you do not want to run the expensive oil cable through internal rooms, the termination can take place at the place where the cable comes out in the same way as indicated above and is then connected to a normal indoor cable leading to the processing plant. In this case, the connection method shown in fig. 2, where the only difference is that the connecting ear 7 is replaced by an axial pin T which protrudes from the collar or disk 6. On this pin is screwed a sleeve 19 belonging to a conical clamping sleeve, the nut of which is denoted by 20. Into the sleeve is the stripped end of the cable 21 stuck and clamped. In order to insulate the current-carrying parts 6, 19 and 20, a sleeve 22 of insulating material is pushed over them. Its upper end fits around the cable 21, and its lower end 23 fits outside the disc or collar 6 and the upper end of the sleeve 8. It rests with a recess 24 on the upper side of the collar 6 as shown.
Ovenfor er det forutsatt at det er en én-lederkabels 1 blymantel som skal forbindes oljetett med avslutningen, men det er innlysende at den samme avslutning også kan forbindes oljetett med hver gren av et blykrltt for en to^ eller tre-ledders kabel. Above, it is assumed that it is a one-conductor cable's 1 lead jacket which is to be oil-tightly connected to the termination, but it is obvious that the same termination can also be oil-tightly connected to each branch of a lead cable for a two- or three-conductor cable.
Avslutningen ifølge oppfinnelsen kan The closure according to the invention can
med fordel anvendes ved spenninger på 1 kV eller høyere. advantageously used at voltages of 1 kV or higher.
