Bushing: Noocyada iyo noocyada kala duwan

Maqaalkani waxa uu ku siin doonaa macluumaad ku saabsan bushings, cayn iyo noocyada. Details aan la dumin doonin qaab-dhismeedka noocyo kala duwan ah, naftooda nooc, iyagoo baaxadda iyo ujeedada. Waxa kale oo la tixgelin doonaa faa'iidooyinka ay la barbardhigo qalabka la mid ah. Ka dib markii reading article ah, ma aha oo kaliya in aad bartaan macluumaad guud oo ku saabsan bushings ah, laakiin sidoo kale ay awoodaan in ay rayi ku dheggan oo ay awoodaan in la kala saaro mid ka mid ah noocyada kale oo ka soo.

Baaxadda bushings ah

Waa maxay bushing? Tani waa qalab gaar ah, shaqada ugu weyn ee kaas oo ah si loo hubiyo in go'doomin xubno tabinta derbiga gudaha ama dibadda galkii ka kaas oo ay Marayaan. Waxay sidoo kale waxaa loo isticmaalaa in la rakibo qalabka qaybinta ee rugood transformer, sidoo kale door weyn natiijooyinka xarumaha Beddelashada Buuxi.

insulators Taageerada waxaa loogu talagalay si qamaar khadadka dusha la busbars live switchgear iyo Goobaha kale ee korontada. Waxaa xusid mudan ku daray in nooca insulators galaas jiray oo caan ka hor, loo isticmaalaa in maanta la badan oo hab doorinta.

bushings waa mid aad u habboon in la isticmaalo ee rugood boosteejada la xidhiidha, kaas oo guryahooda ku shaqeeya.

noocyada kala duwan ee insulators

Bushings kala qaybsan yihiin laba nooc. Nooca ugu horeeya - waa insulators, kuwaas oo loogu talagalay rakibaadda indoor. Waxay waxaa loo isticmaalaa sida-vacuum sare ama a high-voltage boosteejada circuit ee gudbiyeyaasha ku. Bushing foomka gudbiyey laga sameeyey oo galaas, iyo wax soo saarka ku yaal gudaha ul bir ah. Waxaa go'an oo macneheedu yahay flanges bir, cap galaas ku lifaaqan iyo Halabuurka ciid dheg sameeyey.

Nooca labaad ayaa ugu hawlan for dibadda iyo rakibo gudaha. aaladaha noocan oo kale ah waxaa la abuuray feeraha dhexe ee loo qoondeeyey meel fog ka yar midba midka kale ka. Qalabka Kuwan waxaa loogu talagalay ningax oo ka socda qaybaha live lifaaqan switchgear. bushing A noocan ah waxaa loo isticmaalaa at shabakad danab hawlgalka 10, 25, 35, 110 kV, oo hadda hawlgalka ee ka 630 in 11,000 A. ah

Waxa kale oo jira noocyo kale oo insulators, laakiin ay waxaa loogu talagalay codsiga ah diirada u gaar ah. Qalabka nooca socodka waxaa loo baahan yahay switchgear ningax qaybo tabinta for xidhiidha macaamiisha si khadadka gudbinta hawada daalaan. Waxyaabahani waxaa laga sameeyay agabka kiciyey qalcadda in ay design waa adkaysi u xamuulka hadda firfircoon.

Faa'iidooyinka insulators

bushing waa in uu lahaado nolosha dheer, sidaa darteed waxa ay leedahay sifooyinka soo socda:

• caabiga sare xaaladaha hawlgalka dagaal;
• miisaanka yar;
• caabin UV;
• xoog sare;
• Nolosha adeeg dheer,
• cabbir yar.

design IP

Bushings SP waa hantidaan xoog farsamo iyo korontada xad-dhaaf ah, si kastaba ha ahaatee wax ka taas oo ay ka samaysan yihiin, waxaa laga yaabaa in sida soo socota:

• polymer;
• galaas;
• galaas hagaajiyey.

insulator waxaa loogu talagalay in danab burburka ahaa xirmi danab sare. isolators Dibadda joogto ah waa sarkhaansan arrimood deegaanka dibadda, si ay dusha sare waxaa dilaaca. Tani waxaa si gaar ah u sameeyey si loo wanaajiyo hawlgalka ee alaabta.

Insulators loogu talagalay qaybsanyihiin bushing, taageero ama ka joojinta, waxaa kale oo jira habab ka mid ah loo xirxiro meelaynta dhismayaasha iyo dhismaha ama loogu rakibo dibadda.

Gudbinta SP-10 waxaa inta badan laga sameeyey galaas. Hirgelinta wax dhisid ah ee sida insulator ah waxaa lagu go'aamiyaa ka danab ku qiimeeyo iyo inta jeer ee awooda ganacsi. qalab laftiisa ka kooban tahay jirka galaas of qaab cylindrical ah, dhajinta on ulo oo geesaha xidh addoonsi la isticmaalayo hoobiye cement-ciid.

bushings ballanta

Ujeedada ugu weyn ee bushings waa in la go'doomiyo ku kirishbooyada nool, taas oo dhex mari darbiyada iyo ded ah dhismayaasha ama dhismayaasha. insulators noocan oo kale ah ka kooban yihiin galaas a dielectric. Jirku wuxuu la sameeyo qaab dhululubo ah, on top of taas oo ay jirto ul hadda-waday. Celcelis ahaan, heerka guryaha biraha Jaha flanges oo, sida hore u soo sheegnay, loogu talo galay in lagu go'an in ay dusha insulator ah.

SP Bushing at danab qalliin 10 kV laga sameeyey oo galaas, iyo danab hawlgalka aad 35 kV guryaha la sameeyo sidii dhisme kakan ningax oo, ee jeedo, wuxuu ka kooban yahay galaas jirka, taarikada baakadaha, waraaqaha qalabada iyo saliid transformer.

bushings sii kordhaya

Marka bushings kordhaya dibadda kormeero waayo, dildilaaca iyo cillado kale, sida dhaawac laga yaabaa in inta lagu guda jiro dusha gaadiidka ee insulators. Sidoo kale baaro haddii glaze dusha sare ayaa xirto off, kaasoo loo isticmaalo ilaalinta iyo ningax waxyaabaha ku daray.

Insulators waa in lagu rakibaa on dhismayaasha birta kasta si uu u helo wax soo saarka, iyo sidoo kale cimri dherer ah ee taayirada ama khadadka korontada dusha.

Ku xiridda bushings bilaabmaa gelinayn saxan galo, kaas oo ku lifaaqan qaab-dhismeedka ama kulamada. Dheeraad ah, insulators xiran yahay labada dhinac ay u saftay la maqaal qoruhu biraha bir ah isagoo furan qaab eg xadiidka tareenka. Waxa ay size ku xiran tahay xajmiga oo ka mid ah taayirrada iyo xaqiijisatay. On the gunaanad ah article u dhexeeya taayirrada go'an ah taayirada struts dhajinta.

calaamadaynta bushings

Sixitaanka ugu hawlan si ay u muujiyo oo dhan Tilmaamo ee alaabta. Tusaale ahaan, SP-10 marinka insulator ah 630 7.5 UHL1, kuna waari dhexdeeda,

• Iyo - insulator ah;
• P - noqotay;
• 10 - danab hawlgalka caadiga ah ee wax soo saarka ee (kV);
• 630 - ka hawlgala soo saarka caadiga ah ee hadda (A);
• 7.5 - jebinta load (Kn);
• UHL - cimiladii toogasho;
• 1 - category ee hoyga.

danab burburka of PI

Burburka danab SP galaas kala duwanaan karaan ku xiran tahay dhumucda lakabka galaas ah. Iyadoo ay taasi jirto, qaab-dhismeedka insulator ah waxaa lagu go'aamiyaa xoog loo baahan yahay si farsamaysan, lagu qiimeeyo danab tallaabooyin noqnoqashada iyo dheeraad ah ka saarida ee taajka.

Marka bushing 10 kV ma qaadaan tallaabooyin si loo soo saaro Corona ah. Iyada oo voltages magacaaban kor ku xusan 35 kV waxaa loo isticmaalaa tallaabooyinka rakibaadda dhow taajkii ushii ka soo horjeeda flange ah, kaliya ee meesha xiisadda ugu badan ee hawada.

Si looga hortago Corona, insulators macmalay oo aan saabka hawada agagaarka ul bir ah ku amro gudahood insulator ah. Inta lagu guda jiro this SP dusha metallized ul. Si aad u baabi'iyo dhacdo ee dheecaan at SP hoose, sidoo kale ay Dareeri Dhexdeeda metallized dusha iyo dheeraad ah ku xeeldheer.

gunaanad

Malaha qof kasta abid arko khadadka dusha transformer kuwaas oo ku lifaaqan SP ah. Qalabka Kuwan waxaa sidoo kale loo baahan yahay xidhiidhka ka mid ah fiilooyin u rakiban go'an, sababtoo ah iyada oo aan insulators xidhiidh wax aan macquul aheyn ee silig a high-voltage.
