Description
Den foreliggende oppfinnelse vedrører en ny type overslagsvern. The present invention relates to a new type of rollover protection.
Det settes stadig høyere krav til påliteligheten ved over-føring og levering av strøm. Et system med middels høy spenning er kanskje mest utsatt i våre dager, særlig som følge av veltende trær, last av snø og is såvel som klimatiske overspenninger. Increasingly high demands are placed on the reliability of the transmission and delivery of electricity. A system with medium-high voltage is perhaps the most exposed these days, particularly as a result of falling trees, loads of snow and ice as well as climatic overvoltages.
For å forbedre driftspåliteligheten er det utviklet delvis isolerte høyspenningslinjer (OESI-linjer) for middels høye spen-ninger (f.ks. 20 KV). Disse linjer muliggjør kortere faseinter-valler mellom sammenliknet med uisolerte åpne ledninger, og således høyere energitetthet. Isolerte ledninger tillater kan des-suten oppsettes i kortere avstand til bygninger, trær og likn-ende. Dette fører igjen til at linjegatene kan gjøres smalere og derved billigere. To improve operational reliability, partially insulated high-voltage lines (OESI lines) have been developed for medium-high voltages (e.g. 20 KV). These lines enable shorter phase intervals between compared to uninsulated open lines, and thus higher energy density. Insulated cables allow, moreover, to be set up at a shorter distance to buildings, trees and the like. This in turn means that the line streets can be made narrower and thereby cheaper.
Klimatiske overspenninger fører til skader på isolerte åpne ledninger. Til og med kortvarige elektriske buer (på noen få KA) er nok til å gjøre linjeskade på isolerte ledninger. Dette kan imidlertid ikke avverges ved å bestemme utløsningstider for rele-er, og det må derfor frembringes oveslagsbeskyttelse på annen måte. Climatic overvoltages lead to damage to insulated open wires. Even brief electric arcs (of a few KA) are enough to cause line damage to insulated wires. However, this cannot be averted by determining tripping times for relays, and protection must therefore be provided in another way.
Det må anordnes overslagsbeskyttelse på slike steder (be-folkede områder, kryssingssteder osv.) hvor ledningsbrudd kan være farlig for omgivelser og mennesker. Det må også anordnes overslagsvern på steder hvor det sansynligvis vil inntreffe overspenninger. Flashover protection must be provided in such places (populated areas, crossing points, etc.) where cable breaks can be dangerous for the environment and people. Surge protection must also be provided in places where overvoltages are likely to occur.
For tiden monteres det overslagsvern på den ene eller begge ender av en avisolert leningsdel ved et ledningsfestepunkt på hver leder. At present, surge protectors are mounted on one or both ends of a stripped rail part at a cable attachment point on each conductor.
Overslagsvernet øker ledningens masse ved det kritiske ende-punkt for en elektrisk bue, og skaden forårsaket av en elektrisk bue vil bli styrt mot et overslagsvern istedenfor til den aktuelle ledning eller leder. Hver gang isoleringen fjernes fra en ledning (for feste, en kontaktterminal, midlertidig jording, en bar kopling osv.) må overganspunktet mellom en bar ledning og isoleringen beskyttes med et overslagsvern. Overslagsvernets dimen-sjon må velges utifrå kortslutningstrømmen i et nettverk (en del av hovedledningen). The surge protector increases the mass of the wire at the critical end point for an electric arc, and the damage caused by an electric arc will be directed towards a surge protector instead of the relevant wire or conductor. Whenever the insulation is removed from a wire (for fastening, a contact terminal, temporary grounding, a bare connector, etc.) the transition point between a bare wire and the insulation must be protected with a surge protector. The dimension of the surge arrester must be chosen based on the short-circuit current in a network (part of the main line).
Ved installasjonstidspunktet krever de tilgjengelige overslagsvern at den harde og tykke PEX-isolasjon må fjernes. Isoleringen må fjernes over en lang distanse når en ledning festes til f.eks. støtteisolatorer. Det samme må gjøres ved alle for-greninger. Spesielt i kaldt vær er dette en vanskelig og kostbar prosedyre. I områder med åpenbar fare for klimatisk korrosjon, såsom i kystområder, i industrielle klimaer osv, fører fjerning av trådisolasjonen alltid til at linjen lettere utsettes for korrosjon. At the time of installation, the available surge protectors require that the hard and thick PEX insulation be removed. The insulation must be removed over a long distance when a wire is attached to e.g. support insulators. The same must be done for all branches. Especially in cold weather, this is a difficult and expensive procedure. In areas with an obvious risk of climatic corrosion, such as in coastal areas, in industrial climates, etc., removing the wire insulation always makes the line more susceptible to corrosion.
Det er et formål med den foreliggende oppfinnelse å frem-bringe en ny type overslagsvern hvis anvendelse muliggjør og sikrer en betryggende strømforsyning med fritthengende isolerte ledninger. It is an aim of the present invention to produce a new type of surge protector, the use of which enables and ensures a reliable power supply with free-hanging insulated wires.
Dette formål oppnås på grunnlag av de kjennetegnende trekk som fremgår av den kjennetegnende del av det vedlagte krav 1 for et overslagsvern ifølge oppfinnelsen. De uselvstendige krav 2-5 omhandler foretrukne løsninger i forbindelse med en praktisk ut-førelse av oppfinnelsen og øker anvendbarheten av overslagsvernet ifølge oppfinnelsen. This purpose is achieved on the basis of the characteristic features that appear in the characteristic part of the attached claim 1 for a rollover protection according to the invention. The independent claims 2-5 deal with preferred solutions in connection with a practical embodiment of the invention and increase the applicability of the rollover protection according to the invention.
En utførelse av oppfinnelsen skal nå beskrives mer detaljert under henvisning til de medfølgende tegninger, hvori: An embodiment of the invention will now be described in more detail with reference to the accompanying drawings, in which:
Fig. 1 viser anvendelse av et overslagsvern. Fig. 1 shows the use of a rollover guard.
Fig. 2 viser i perspektiv et overslagsvern ifølge oppfinnelsen. Fig. 3 viser et endesnitt (aksialt) av overslagsvernet ifølge fig. 2. Fig. 2 shows in perspective a rollover guard according to the invention. Fig. 3 shows an end section (axial) of the rollover guard according to fig. 2.
Fig. 4 viser et sidesnitt av det samme overslagsvern. Fig. 4 shows a side section of the same splash guard.
Fig. 5 viser et plansnitt av overslagsvernet. Fig. 5 shows a plan section of the rollover guard.
Fig. 1 viser to overslagsvern 1 som er festet til en isola-sjonsbelagt åpen linje som skal beskyttes, og linjen er med en bindingstråd festet til en støtteisolator som igjen bæres av et tverrstag 4 av metall. I dette tilfelle, hvor strømforsyningen antas å skulle skje i begge retninger, er overslagsvernene 1 forbundet med hverandre med en ledning 3 av aluminium. Overslags-vernenes horn 3 rager på skrå nedad fra linjen som skal beskyttes. For eksempel vil en elektrisk bue, som dannes av en lynindu-sert puls, utlades ved spissen av hornet 2 til tverrstaget 4, eller mellom ulike faser fra hornspiss til hornspiss. Dersom lin-jens strømsforsyning kun skjer den ene vei, er overslagsvernet 1 kun nødvendig på den side av støtteisolatoren som er nedstrøms for støtteisolatoren i retning av strømforsyningen. Fig. 1 shows two surge protectors 1 which are attached to an insulation-coated open line to be protected, and the line is attached with a binding wire to a supporting insulator which is in turn supported by a metal transverse brace 4. In this case, where the power supply is supposed to take place in both directions, the surge protectors 1 are connected to each other with a wire 3 made of aluminium. The horn 3 of the surge protectors projects obliquely downwards from the line to be protected. For example, an electric arc, which is formed by a lightning-induced pulse, will be discharged at the tip of the horn 2 to the crossbar 4, or between different phases from horn tip to horn tip. If the line's power supply only takes place one way, the surge protector 1 is only necessary on the side of the support insulator which is downstream of the support insulator in the direction of the power supply.
I det etterfølgende skal konstruksjonen til et overslagsvern beskrives mere detaljert. En hoveddel 5 og en pressdel 6 er sam-menmontert ved hjelp av to spennskruer 15 som kan skrues til for å tvinge pressdelen 6 mot hoveddelen 5. Hoveddelen 5 er utstyrt med en kjeve 7 mens pressdelen 6 er utstyrt med en motsvarende kjeve 8. En tråd eller ledning som skal beskyttes kan klemmes sammen mellom kjevene 7 og 8. For å sikre metallkontakt gjennom isolasjonen på en isolert tråd uten at isolasjonen fjernes, er de nevnte kjever 7 og 8 forsynt med tenner 9 og 10 som har en lengde som minst motsvarer isolasjonstykkelsen på den tråd som skal beskyttes. Det er klart at det samme resultat kan oppnås ved å for-syne kun den ene av kjevene 7,8 med tenner. In what follows, the construction of a rollover guard will be described in more detail. A main part 5 and a pressing part 6 are assembled together by means of two clamping screws 15 which can be screwed to force the pressing part 6 against the main part 5. The main part 5 is equipped with a jaw 7 while the pressing part 6 is equipped with a corresponding jaw 8. wire or wire to be protected can be clamped together between the jaws 7 and 8. In order to ensure metal contact through the insulation on an insulated wire without removing the insulation, the said jaws 7 and 8 are provided with teeth 9 and 10 which have a length that at least corresponds to the insulation thickness of the wire to be protected. It is clear that the same result can be achieved by providing only one of the jaws 7,8 with teeth.
På den andre side av aksialplanet gjennom fastspennings-skruene 15 er hoveddelen 5 og pressdelen 6 utstyrt med kjever 11 henholdsvis 12. Mellom kjevene 11,12 er det anordnet en mellomliggende kjeve 13 som ved hjelp av en fjær 14 holdes anspent mot hoveddelens 5 kjeve 11. Overslagsvernets horn 2 er anordnet mellom hovedelens kjeve 11 og den mellomliggende kjeve hvor den kan innstilles og fastholdes i posisjon uten å falle ut selv når spennskruene 15 ikke er tiltrukket, og pressdelen 6 er øverste stilling. On the other side of the axial plane through the clamping screws 15, the main part 5 and the pressing part 6 are equipped with jaws 11 and 12, respectively. Between the jaws 11,12 there is an intermediate jaw 13 which is held in tension against the jaw 11 of the main part 5 by means of a spring 14 The rollover guard's horn 2 is arranged between the jaw 11 of the main element and the intermediate jaw where it can be adjusted and held in position without falling out even when the clamping screws 15 are not tightened, and the pressing part 6 is in the uppermost position.
Mellom den mellomliggene kjeve 13 og pressdelens kjeve 12 er det dannet et tredje kjevepar, og mellom disse kjever kan det fastgjøres en bue-ledende tråd 3. Between the intermediate jaw 13 and the jaw 12 of the pressing part, a third pair of jaws is formed, and between these jaws an arc-conducting wire 3 can be attached.
Overslagshornet 2 er anordnet med en bend 16 med en vinkel The overflow horn 2 is arranged with a bend 16 with an angle
på f.eks. 45°. Vinkelen kan variere innen området 30-90°. Lengden på hornet 2 nedstrøms for benden 16 er dimensjonert tilstrekkelig til å motstå elektrisk bue-overslag som følge av overspenninger i ledningens levetid, og lengden er fortrinnsvis over 180 mm. Overslagshornet 2 kan anordnes med en rekke bender. Det essentielle on e.g. 45°. The angle can vary within the range 30-90°. The length of the horn 2 downstream of the bend 16 is dimensioned sufficiently to withstand electric arcing as a result of overvoltages during the lifetime of the line, and the length is preferably over 180 mm. The overflow horn 2 can be arranged with a number of benders. The essentials
er at det opprinnelige utladningspunkt kan styres slik at det inntreffer ved spissen av overslagshornet 2 som er i en tilstrekkelig avstand fra selve overslagsvernet og fra tråden som skal beskyttes, for at tråden ikke skal påføres skader av den resulterende bue. is that the initial discharge point can be controlled so that it occurs at the tip of the flashover horn 2 which is at a sufficient distance from the flashover guard itself and from the wire to be protected, so that the wire is not damaged by the resulting arc.
Konstruksjonen av et overslagsvern og tilhørende overslags-horn dimensjoneres slik at det kan motstå forekomsten av en elektrisk bue (som skyldes et lynnedslag) i ledningens levetid. The construction of a surge protector and associated surge horn is dimensioned so that it can withstand the occurrence of an electric arc (caused by a lightning strike) during the life of the line.
Overslagsvernet ifølge oppfinnelsen kan benyttes og anvendes når en tråd skal jordes midlertidig, idet overslagshornet 2 tjener som kontaktpunkt for en jordingselektrode. Heller ikke i et slikt tilfelle er det nødvendig å foreta en brysom fjerning av trådisolasjonen for å etablere et jordingspunkt. Således er det ikke i noe tilfelle fare for at tråden vil bli utsatt for øket korrosjon siden isolasjonen ikke fjernes. Sporene 9 og 10 mellom tennene 7 og 8 kan også smøres ved å benytte et beskyttende smøremiddel slik at fuktigheten ikke kan komme i kontakt med tråden. Overslagsvernet kan også anbringes i et eget beskyttel-seskammer. The flashover guard according to the invention can be used and is used when a wire is to be earthed temporarily, the flashover horn 2 serving as a contact point for an earthing electrode. Even in such a case, it is not necessary to carry out a hasty removal of the wire insulation to establish an earthing point. Thus, there is in no case a danger that the wire will be exposed to increased corrosion since the insulation is not removed. The grooves 9 and 10 between the teeth 7 and 8 can also be lubricated by using a protective lubricant so that moisture cannot come into contact with the thread. The splash guard can also be placed in a separate protection chamber.
Ved overslagsvernet ifølge oppfinnelsen lettes installa-sjonsarbeidet, og det kan spares både tid og kostnader. Overslagsvernet fungerer tilfredstillende også gjennom en hard PEX-isolator, og monteringen kan gjennomføres med vanlig verktøy. With the rollover guard according to the invention, the installation work is made easier, and both time and costs can be saved. The splash protection also works satisfactorily through a hard PEX insulator, and assembly can be carried out with ordinary tools.
