Ngokutshintshela kwethu rhoqo kwiinkqubo zombane ezingaphantsi komhlaba, imfuneko yokusasazwa okuthembekileyo, okukhuselekileyo nokuguquguqukayo iyanda imihla ngemihla. Oku kufuna ukuseta okucwangcisiweyo kwezihlanganisi ze-loadbreak elbow ukuze ziqhagamshele kwaye zikhuphe iisekethe ezisebenza ngamandla ngokukhuselekileyo.
Ezi zixhumi zidibanisa iintambo ezingaphantsi komhlaba kwiibhushi ezifileyo zangaphambili kwiitransformer ezifakelwe kwi-padmount, ziqinisekisa unxibelelwano olukhuselekileyo noluthembekileyo phakathi kweentambo zombane kunye neetransformer.
Ngoko ke, yintoni kanye kanyeIsixhumi sengqiniba yeLoabreak? Ingaba isebenza kanjani?
Masiphendule le mibuzo, phakathi kweminye emininzi, kweli nqaku.
I-Load brake elbow sisixhumi esinokwahlulwa, esigqunyiweyo, esisetyenziswa kwiinkqubo ezininzi ze-voltage ephantsi ukuya kwephakathi yokutshintsha umthwalo ngamandla. Izixhumi ze-Load break elbow zisetyenziselwa ukuqhagamshela iintambo ezingaphantsi komhlaba, ii-voltage eziphakathi kwi-transformers, i-switchgear kunye nezinye izixhobo.
Ezi ziqhagamshelo zibonelela ngoqhagamshelo olukhuselekileyo nolungena emanzini, kwaye zenzelwe ukwenza okanye ukuqhekeza uqhagamshelo phantsi komthwalo. Zikalwe kakhulu kwiinkqubo ze-15 kV, 25 kV kunye ne-35 kV.
Ukuqinisekisa ukuba ziyatshintshana kwaye zisebenza ngokukhuselekileyo phantsi komthwalo nakwiinkqubo ezahlukeneyo zombane, uninzi lweengqiniba zokwaphuka komthwalo ziyahlangabezana nemigangatho yoshishino efanaIEEE 386.
Iingqiniba zesonka somthwalo zivumela ukuqhawuka kunye nokunxibelelana kwakhona ngoncedo lwezixhobo ezinamathelayo. Nazi ezinye zeempawu zayo eziphambili:
Lo ngumsebenzi wabo ophambili, njengoko banokuphazamisa baze badibanise uqhagamshelo olufikelela kwi-200 A, ngelixa behlukanisa okanye behlukanisa izixhobo ezahlukeneyo ngaphandle kokunciphisa amandla enkqubo yonke.
Incam ye-electrode yeseramikhi idlula umzimba wengqiniba kwaye inceda ukucima i-arc eyenziwe xa yahlula uqhagamshelo phantsi komthwalo.
Abaqhubi banokusebenzisa izixhobo zombane ezigqunyiweyo (ii-hot sticks) ukuze bakhuphe baze bafake ingqiniba. Apha, indlela yokusika isetyenziswa ukunciphisa uxinzelelo lombane kunye nokuguguleka, ngelixa belawula ukuqaliswa kwe-arc.
Iindawo zokuvavanya amandla zifakwe kwiingqiniba zokwaphuka komthwalo ukuqinisekisa ukuba uqhagamshelo luyasebenza ngaphambi nasemva kokuqhawuka. Ezi ndawo zokuthwala amandla azidibani ne-conductor ephambili.
Zonke ezi zinto zisebenza ngokuvumelana ukuvumela izihlanganisi zokwaphula umthwalo ukuba ziqhagamshelane kwaye zikhuphe uqhagamshelo oluphilayo ngelixa zigcina ukhuseleko lomqhubi kunye nenkqubo.
Izixhumi zokwaphuka komthwalo ziza ngeentlobo ezahlukeneyo ngokusekelwe kudidi lwevolthi, indawo yesicelo kunye noqwalaselo. Makhe sithethe ngezinye zezona ntlobo zisetyenziswa kakhulu:
Iingqiniba zokwaphuka komthwalo ziza kwiindidi ezahlukeneyo zevolthi, ezinye zazo zezi:
15kV:Zenzelwe iisekethe ezifikelela kwi-15 kV, ezine-current eqhubekayo ye-200 Amperes. Ezi zixhumi ze-elbow ze-15 kV zikhuselekile ngokupheleleyo, zintywiliselwa emanzini kwaye ngamanye amaxesha zine-bimetal contacts.
25kV:Ezi Iingqiniba zokwaphula umthwalo ze-25 kVZilinganiswa kwiinkqubo ukuya kuthi ga kwi-24 kV, zihlala zikwi-250 A continuous current enomthamo wokugqithisa we-300 A iiyure ezi-8. Zixhasa iintambo ezigqunyiweyo ze-XLPE okanye ze-EPR ezinee-cross-sections ze-conductor ukusuka kwi-~25–120 mm². Zisetyenziswa rhoqo kwiinkqubo zombane zanamhlanje kwaye zibonelela ngendlela ekhuselekileyo nekhuselekileyo yokudibanisa/ukunqumla iisekethe ezingaphezulu.
35kV:Nangona 25Iingqiniba zokwaphuka komthwalo we-KvZisetyenziswa rhoqo, i-35 kV ikwasetyenziswa kwezinye izicelo ezithile. Zinokumelana nombane oqhubekayo ofikelela kwi-200 Amperes kunye nomlinganiselo we-voltage okanye ukuya kuthi ga kwi-35 kV. Ukulawula le voltage inkulu, zine-insulation ye-EPDM ephiliswe nge-peroxide kunye ne-semiconducting shield, i-coppertop compression connector, i-tin-plated copper probe ene-arc-follower tip, kunye neendawo zovavanyo ze-capacitive ozikhethelayo.
Iziqhagamsheli zokuvala umthwalo ziza ngeendlela ezahlukeneyo ukuze zilungele usetyenziso olwahlukeneyo
Ingqiniba yokuvala umthwalo eqhelekileyo:Ezi zisetyenziselwa ukuqhagamshela intambo enye kwisixhobo esinye (umz. i-transformer, i-switchgear). Zisebenzisa iincam ze-ceramic probe eziphumayo ukuxhasa imisebenzi enamandla.
Ingqiniba yohlobo lwe-junction:Zikwabizwa ngokuba zii-multi-way okanye ii-tee configuration elbows. Zivumela ukudibana ngokuqhagamshela iintambo ezininzi ngaphakathi kwendlu enye egqunyiweyo. Uqwalaselo oluqhelekileyo luquka ii-2-point, 3-point, kunye ne-4-point junction elbows ezisetyenziswa kwi-complex distribution layouts.
Ngenqaku lovavanyo olunamandla:Ezi ngqiniba zokwaphuka komthwalo ziquka i-sensor ebunjiweyo, ekwaziyo ukuthwala umthwalo ukubonisa i-voltage yesekethe (ngesiqhelo malunga ne-10–12% ye-voltage yesigaba ukuya emhlabeni). Olu phawu lwenza ukuba kuqinisekiswe i-voltage ekhuselekileyo ngaphandle kokunika amandla isixhumi ngokuthe ngqo.
Ngaphandle kwendawo yovavanyo:Ezi zifanelekile kwiindawo apho uvavanyo lwe-voltage lwenziwa khona kwenye indawo, ezi ngqiniba azinakubonelela ngempendulo ye-voltage yesigaba ukuya emhlabeni ngoko nangoko.
Nangona uninzi lweengqiniba eziqhawula umthwalo ziza noyilo olukwaziyo ukuntywiliselwa emanzini, ezinye ziza noyilo olukwaziyo ukumelana nokugqwala.
Uyilo olungena emanzini
Ezi zakhiwo zingaphantsi kwamanzi zinokusebenza ngokuthembekileyo phantsi kwamanzi okanye kumhlaba ogcweleyo xa zidibene kakuhle nezikhonkwane okanye iiplagi ezifanelekileyo. Umzekelo, i-Anhuang'sIingqiniba zokwaphula umthwalo ze-25 kVinikezela ngonxibelelwano olungena manzi ngokupheleleyo nolwahlulwe.
Uyilo Olungagqwaliyo
Ezinye iingqiniba zokwaphuka komthwalo zisetyenziswa kwiindawo ezirhabaxa, ezifana neendawo ezikunxweme okanye izityalo zeekhemikhali. Zibonelela ngoqhagamshelo olugciniweyo nolunokuhlanjwa emanzini olunezixhobo zentsimbi engagqwaliyo kunye nezixhobo zerabha ze-EPDM ezenzelwe ukumelana nokonakaliswa kwendalo kwiimeko ezinzima.
Nazi ezinye zeendlela zokusebenzisa iingqiniba zokuvula umthwalo:
Ukusasazwa kwamandla angaphantsi komhlaba
Iingqiniba zokwaphula umthwalo zisetyenziswa kakhulu ukuqhagamshela iintambo ezingaphantsi komhlaba ze-voltage ephakathi kwiitransformer, iswitchgear, kunye nezinye izixhobo ngaphandle kokuphazamisa inkonzo.
Iitransformer kunye neeswitchgear ezifakwe kwi-pad
Zivumela ukusebenza okukhuselekileyo nokunamathelayo xa kuqhagamshelwa okanye kunqunyulwa izixhobo kwiinkqubo ezisebenzayo ezifana neetransformers ezifakwe kwi-pad kunye neswitchgear.
Ufakelo lwemizi-mveliso, izixhobo zokusebenza kunye norhwebo
Iingqiniba zokunciphisa umthwalo zisetyenziswa kuzo zonke izitishi zombane, iinkqubo zamandla zoshishino, kunye nezakhiwo zorhwebo apho kufuneka khona ukuhlukaniswa kweendawo kunye nokutshintshwa komthwalo ophilayo.
Iifama zamandla omoya, elanga kunye namandla avuselelekayo
Ezi zilungele ukufakelwa okuhlaziyekayo (ezifana neefama zomoya kunye nelanga) apho imisebenzi eguquguqukayo nesebenzayo inceda ukunciphisa ixesha lokungasebenzi ngexesha lokulungiswa.
Iinkqubo zeMigodi kunye noololiwe
Isetyenziswa kwiindawo ezinzima ezifana nemisebenzi yemigodi kunye neenkqubo zombane zesitimela okanye zemetro ukugcina umbane oqhubekayo ngelixa kubekwa iindawo ezithile ukuze zisebenze.
Izixhumi ze-elbow zokwaphuka komthwalo ziyimfuneko xa ufuna ukwahlula ezinye iindawo zenkqubo yombane engaphantsi komhlaba enevolthi ephakathi. Zibonelela ngendlela ethembekileyo nekhuselekileyo yokulungisa ezinye iindawo zeesekethe ngaphandle kokuphazamisa umbane ngokubanzi.
Ukuba ujonge ukuthengaIzihlanganisi ze-elbow ze-25 kV loadbreakkwisicelo sakho, kufuneka ujonge uluhlu lwe-Anhuangiingqiniba zokwaphuka komthwalo.
