Description

Fremgangsmåte for isolering av staver eller spoler for høyspennings-statorviklinger.
Den foreliggende oppfinnelse vedrorer en fremgangsmåte for isolering av staver eller spoler i hoyspenningsstatorviklinger som såvel i spordelen som i viklingshodedelen er forsynt med båndisolasjon.
Av hoyspennings-statorviklinger forlanges en korrekt dimen-sjonert, tett isolasjon med stor elektrisk fasthet i spordelen. Til boyleforbindelsene for hodedelene på begge sider stilles vanligvis mindre strenge krav i så henseende. Det er kjent to fremgangsmåter for fremstilling av slike isolasjoner.
Ifolge den ene anbringes den i tallrike lag overlappende påviklede isolasjon gjennomgående og på samme måte i spordelen som i hodedelen. Om onsket, kan lagantallet og dermed isola-sjonens tykkelse gjores forskjellig for viklehodet og spordelen. Denne isolasjonstype kalles en likeformet, gjennomgående viklet isolasjon.
I det annet tilfelle anbringes spordelens og boylens isolasjoner hver for seg, og det kan benyttes forskjellige isolasjonsmateri-aler eller anbringelsesmetoder for de to deler. Det er således meget alminnelig å vikle en passende folie i en bred bane på spordelens lederbunt og presse den således dannede hylse fast under trykk- og eventuelt varmepåvirkning. For hodedelene kan det på grunn av boylens krumning bare benyttes båndisolasjon.
En således fremstilt isolasjon betegnes som ikke likeformet (diskontinuerlig) isolasjon. For ikke å forringe den elektriske sikkerhet på grunn av skjotene mellom spor- og boyleisolasjon, er det vanlig å gjore spordelens isolasjon lengre og påforé
den et godt stykke over statorens jerndel. På den koniske avslutning av spordelens isolasjon vikles så hodets båndisolasjon.
Et formål med den foreliggende oppfinnelse er å tilveiebringe
en hoy elektrisk fasthet i overgangen mellom spordelens og hodedelens isolasjon.
Dette oppnås ifolge oppfinnelsen ved at vekselvis er lederbuntens spordel henholdsvis hodedel omviklet med et sjikt av en adskilt båndisolasjon for innbyrdes forskyvning av overgangsstedet mellom de to isolasjoner fra sjikt til sjikt.
På denne måte vil det ved anbringelsen av isolasjonen på staven hhv. spolen overhodet ikke oppstå noe egentlig skjotested mellom de to isolasjoner, men hele isolasjonen forloper praktisk talt likeformet og kontinuerlig. Begge isolasjoner anbringes med en viss overdekking av sjiktene.
Oppfinnelsen skal beskrives nærmere under henvisning til tegningen, hvorpå figuren viser en del av en stav for en statorvikling i lengdesnitt. Stavens isolasjon utfores ifolge oppfinnelsen som folger:
Statorplatenes ende er antydet med b, for at den viklede
stavens stilling i forhold til statoren skal fremgå klart. På lederbunten a vikles forst et lag av et isolasjonsbånd av en eller annen isolasjon frem til det omtrentlige sted hvor overgangen fra den ene isolasjon til den annen skal opprettes, forst f.eks. laget n^ for sporisolasjonen. For bedre oversiktlighets skyld er båndets vindinger her vist kant i kant og ikke overlappende slik det er vanlig å legge dem. Til laget n^ slutter seg det nederste lag c, for boyleisolasjonen. Over dette anbringes lag c ? for bbyleisolasjonen og i tilslutning lag for spordelens isolasjon. På lignende måte anbringes derefter ytterligere lag n^, n^ m.v. for sporisolasjonen og tilsvarende lag c^/ c. m.v. for boyleisolasjonen vekselvis på staven inntil den onskede isolasjonstykkelse er oppnådd. Det må bare påaktes at skjotestedene mellom sporisolasjonens lag og de tilsvarende lag for boyleisolasjonen blir beliggende innenfor området for overgangen. Selvsagt er det også mulig å begynne med samme del av isolasjonen ved hvert nytt båndlag, dvs. å begynne enten med sporisolasjonen eller boyleisolasjonen, i stedet for å skifte som omtalt.
Som det vil fremgå av figuren, kan lagskjotene for de to isolasjoner forskyves i lengderetning fra lag til lag ved anbringelsen av isolasjonsbåndet. På denne måte oppnås enda storre elektrisk fasthet på overgangsstedet mellom de to isolasjoner, og ved bruk av bånd med forskjellig tykkelse for de to isolasjoner fås en jevnere overgang, dvs. man unngår praktisk talt utbukt-ning av isolasjonen på overgangsstedet. Ved bruk av forskjelligartede båndisolasjoner med forskjellig tykkelse for spor- og boyledelen kan det også tilveiebringes en utjevning uten ulemper for den elektriske fasthet på overgangen ved anbringelse av et storre antall lag på den side hvor båndet er tynnere og ved å
la to eller flere lag av samme bånd folge umiddelbart efter hverandre også på overgangsstedet.
Ved den beskrevne fremgangsmåte oppnås en intim overlapping av spordelens og boylens isolasjoner på overgangsstedet mellom de to isolasjoner. Det kan således opprettes en gjennomgående isolasjon for spordelen og viklehodet av statorviklingers staver eller spoler selv om det benyttes forskjelligartede båndisolasjoner for de to deler.

Claims (3)

  1. Fremgangsmåte for isolering av staver eller spoler i hoyspenningsstatorviklinger som såvel i spordelen som i viklingshodedelen er forsynt med båndisolasjon, karakterisert ved at vekselvis er lederbuntens spordel henholdsvis hodedel omviklet med et sjikt av en adskilt båndisolasjon for innbyrdes forskyvning av overgangsstedet mellom de to isolasjoner fra sjikt til sjikt.
  2. 2. Fremgangsmåte som angitt i krav 1, karakterisert ved at det for de to isoleringer anvendes bånd med forskjellige tykkelser.
  3. 3. Fremgangsmåte som angitt i krav 1, karakterisert ved at det for de to isoleringer anvendes bånd med samme tykkelse.
