Bushing: iintlobo kunye neentlobo

Eli nqaku liza kunika ingcaciso malunga bushings, ngeentlobo zazo kunye neendidi. Iinkcukacha ziya idilizwe isakhiwo ezahlukahlukeneyo, iintlobo ngokwabo, imihlaba yabo kunye nenjongo. Oku nazo ziya kuthathelwa ingqalelo izinto zabo xa kuthelekiswa izixhobo ezifanayo. Emva kokufunda eli nqaku, ufunda kuphela ulwazi ngokubanzi malunga bushings, kodwa ube uyakwazi ukuwuqonda iileyibhile kwaye bakwazi ukwahlula uhlobo olunye kolunye.

Kwenkululeko the bushings

Yintoni bushing? Esi sisixhobo okhethekileyo, umsebenzi engundoqo iyileyo kukuqinisekisa Ukuqhela elements conductive eludongeni yangaphakathi okanye yangaphandle esingxobeni bayangena abadlula. Kwakhona zisetyenziswa ukufakelwa kwezixhobo distribution of sezitishana sombane, kwakhona ukudlala indima kwiziphumo Gqibezela amaziko utshintshayo.

insulators Inkxaso ziyilelwe ukulungisa imigca ezihamba kunye busbars live nokucima umbane kunye nezinye nofakelo zombane. Iyafuna oqhube porcelain insulators uhlobo ezibe ethandwayo ngaphambili, isetyenziswe kule mini a lot zokuguqulwa.

Ezi bushings zibe lula kakhulu ukuba ukusebenzisa i sezitishana kwiitheminali uxhulumaniso, ukusuka apho kunikwe amakhaya.

iintlobo insulators

Bushings zahlulwe iindidi ezimbini. Uhlobo lokuqala - i insulators, leyo eyenzelwe ukuba ufakelo endlwini. Zisetyenziswa phezulu-emoyeni okanye uqhagamshelwano lwetshiphu emsebenzi-ombane kwiitheminali ukujikeleza + abaguquli. ifomu lungeniswe Bushing wenziwe imveliso yephondo, kwaye imveliso yomsebenzi ibekwe ngaphakathi ngentonga yentsimbi. It omiswe ngendlela flanges ezenziwe ngentsimbi, ikepusi porcelain eqhotyoshelweyo kunye nokwakheka nesanti ancamathelayo.

Uhlobo lwesibini wabelwa ukuba lwangaphandle kunye fakelo engaphakathi. izixhobo ezinjalo zidalwe iimbambo eliphakathi zicwangciswe kumgama encinane enye kwenye. Ezi zixhobo zenzelwe usambathisa ukusuka kwiindawo eziphilayo zifakwe nokucima. A bushing yale hlobo lisetyenziswa kwi-network ombane yokusebenza 10, 25, 35, 110 kV, kwaye yokusebenza ngoku ukusuka 630 ukuya 11,000 A.

Kukwakho nezinye iintlobo insulators, kodwa zenzelwe ukuba isicelo setekeni ethile. izixhobo uhlobo flow ziyafuneka usambathisa nokucima iindawo conductive yoqhagamshelo abathengi ukuba isondo neentambo zothumelo emoyeni. Ezi iimveliso ezenziwe ngezinto yaphakamisa inqaba kuyilo yabo iyamelana imithwalo ezinamandla yangoku.

buhle insulators

Le bushing kufuneka ube nexesha elide, ngoko ke neneempawu zilandelayo:

• ukumelana eliphezulu kwiimeko banqande yokusebenza;
• ubunzima elincane;
• UV ukumelana;
• amandla eliphezulu;
• ubomi inkonzo ende;
• ineenkalo encinci.

design IP

Bushings SP kufuneka babe namandla kakhulu ngoomatshini kunye umbane, nangona kunjalo izinto ukusuka apho kwenziwe, babe ngolu hlobo lulandelayo:

• Polymer;
• imveliso yephondo;
• glass ukuzibamba.

Le yokwambathisa yenzelwe ukuqhawuka ombane yaba ukudibana ombane aphezulu. isolators bangaphandle ahlala phantsi kweempembelelo iimeko zangaphandle kokusingqongileyo, ngoko ubuso babo zila. Oku kwenziwa ngokukodwa ukuphucula ukusebenza imveliso.

Insulators kwenzelwe nohlulwe bushing, inkxaso okanye ukuxhonywa, zikhona iindlela yofakelo ukuba abe nako ukufakwa izakhiwo kunye nezakhiwo okanye ufakelo ngaphandle.

Watyhutyha SP-10 Amaxesha amaninzi owenziwe imveliso yephondo. Ukuphunyezwa eyakhayo i yokwambathisa loo limiselwa ukusuka ombane rated kunye nezihlandlo yezorhwebo. Icebo yakhiwe yequmrhu porcelain isimo zezindlu, ekhwele phezu asi leyo elintlangothi angenziwa yesondo kusetyenziswa isamente-isanti udaka.

bushings Ukubekwa

Eyona njongo ephambili yale bushings kukuba ekwahluleni izinikezeli ephilayo, uwele iindonga kunye isigubungelo izakhiwo okanye izakhiwo. insulators ezinjalo sakhiwa porcelain Heating. Iqumrhu yenziwe ngohlobo itankana, phezu apho kukho ngentonga yangoku-ethwele. Kwi-avareji, inqanaba izindlu metal enyusiweyo flanges leyo, njengoko kuchaziwe ngaphambili, ekujongwe ukuba zigxunyekwe kumphezulu yokwambathisa.

Bushing SP endaweni ombane yokusebenza ukuya kwi-10 kV wenziwe imveliso yephondo, kwaye kwi ombane yokusebenza kunene 35 kV izindlu yenziwe njenge nesakhiwo yokugquma entsonkothileyo leyo, nayo, iquka porcelain umzimba, iipleyiti ikhadibhodi, iphepha zokwambathisa ezikhoyo kunye namafutha sombane.

bushings Ayanda

Xa bushings obandayo yangaphandle kuhlolwa iintanda kunye nezinye iziphene, njengoko ise nokuba yonakele ngexesha zothutho ubuso insulators. Kwakhona ihlole ingaba njengeceba kumphezulu ityekile off, esetyenziswa iimveliso ngokhuseleko usambathisa longeziwe.

Insulators kufuneka zifakwe kwi naziphi na izakhiwo metal kukhuselwe imveliso, kwakunye phakade amavili okanye iingcingo zombane ezihamba.

Ifaka bushings iqala ngokubeka isitya yokungena, encamathele isakhiwo okanye naliphi na lwemidlalo. Ngaphezu koko, le insulators uvaliwe kwi macala ngo CAPS kunye izahlulelo isinyithi metal ukuba imingxunyana buxande efana kaloliwe kaloliwe. isayizi yazo kuxhomekeke kubukhulu ivili kunye kuqiniswe. Ngomhla izigqibo inqaku phakathi ivili esisigxina ezikhaphukhaphu imvelaphi inyuselwa khona amavili.

Gcoba bushings

Yokukorekisha isabelo ukuze izakuphawula zonke iimpawu kwimveliso. Umzekelo, i-SP-10 yokwambathisa sicatshulwa 630 7.5 UHL1, apho:

• Kwaye - i yokwambathisa;
• P - Kwathi;
• 10 - the normal yokusebenza ombane imveliso (kV);
• 630 - eziqhelekileyo yokusebenza imveliso yangoku (A);
• 7.5 - umthwalo ngokwaphula (KN);
• UHL - iimeko zemozulu lokubulawa;
• 1 - kuhlobo yokuhlala.

Ulwahlulo zinamandla PI

Ulwahlulo ombane porcelain SP inokuba nomahluko ngokuxhomekeke Ebubanzini esibekwa imveliso yephondo. Ngaphandle koku, ubume yokwambathisa umiselwa ngamandla efunekayo mechanical, rated ombane kwamanyathelo sifana kakhulu kwaye ezongezelelweyo ukususwa isithsaba.

Xa kV bushing 10 musa ukuthatha amanyathelo ukususa corona. Kunye yombane ngegama ngasentla 35 kV zisetyenziswa ufakelo amanyathelo kufuphi isithsaba yentonga malunga esisangqa, kanye kwindawo apho abantu imimoya ubuninzi emoyeni.

Ukuthintela corona, insulators ziveliswe ngaphandle kwisisu umoya ehlabathini intonga yesinyithi elahliweyo ngaphakathi yokwambathisa. Ngeli SP umphezulu metallized ngentonga. Ukuze kupheliswe isenzeko alahlwayo kwi SP ezantsi, nayo ngaphantsi komhlaba metallized kunye olunye lusekelwe.

isiphelo

Mhlawumbi wonke umntu owakha wambona imigca kwentloko sombane leyo iqhotyoshelwe SP. Ezi zixhobo nabo badinga ukuba udibaniso lwe kwiingcingo ukuya ufakelo amisiweyo, ngenxa yokuba kungekho insulators uxhulumaniso akunakwenzeka of kwiingcingo zombane ombane.
