Uyilo lwe-bushing kwiziguquli zesikhululo esingaphantsi alululanga njengeehlahla kwi-padmount transformers. I-bushings kwi-padmount ihlala ikwikhabhinethi phambi kweyunithi ene-low-voltage bushings ngasekunene kunye ne-high-voltage bushings ngakwesobunxele. Iziguquli zesitishi esincinci zinokuba nezihlahla ezibekwe phantse naphi na kwiyunithi. Ngaphezu koko, kuxhomekeke kwisicelo esichanekileyo, umyalelo we-substation bushings unokwahluka.
Konke oku kuthetha ukuba xa ufuna i-substation transformer, qiniseka ukuba uyayazi i-bushing layout ngqo phambi kokuba ubeke iodolo yakho. Gcina ukhumbule inqanaba phakathi kwe-transformer kunye nesixhobo oxhuma kuso (i-breaker, njl.) Ubume be-bushing kufuneka bube ngumfanekiso wesibuko, kungekhona okufanayo.
Indlela yokukhetha ukwakheka kwee-bushings
Kukho izinto ezintathu:
- Iindawo Zokutyholwa
- Izigaba
- Iindawo ezibiyelweyo zetheminali
Iindawo Zokutyholwa
I-American National Standards Institute (ANSI) inikezela ngokutyunjwa kwendawo yonke yokubhala iileyibhile kumacala okuguqula: I-ANSI Icala le-1 "lingaphambili" le-transformer-icala leyunithi elibamba i-valve yokudonsa kunye ne-nameplate. Amanye amacala atyunjwe ahamba ngokwewotshi ejikeleze iyunithi: Ukujongana nomphambili we-transformer (Icala loku-1), Icala lesi-2 licala lasekhohlo, icala lesi-3 licala elingasemva, kwaye icala lesi-4 licala lasekunene.
Ngamanye amaxesha i-substation bushings ingaba phezulu kwiyunithi, kodwa kwimeko enjalo, iya kufakwa kumgca wecala elinye (kungekhona phakathi). I-nameplate ye-transformer iya kuba nenkcazo epheleleyo ye-bushing layout yayo.
Isigaba soNxibelelwano
Njengoko unokubona kwisikhululo esiboniswe ngasentla, i-low-voltage bushings ihamba ukusuka ekhohlo ukuya ekunene: X0 (i-neutral bushing), X1, X2, kunye ne-X3.
Nangona kunjalo, ukuba izigaba bezichasene nomzekelo wangaphambili, uyilo luya kuguqulwa: X0, X3, X2, kunye X1, ukusuka ekhohlo ukuya ekunene.
I-bushing engathathi hlangothi, echazwe apha kwicala lasekhohlo, inokufumaneka kwakhona kwicala lasekunene. I-bushing engathathi hlangothi inokuthi ibekwe phantsi kweminye i-bushings okanye kwi-lid ye-transformer, kodwa le ndawo ayiqhelekanga.
Tiindawo ezivaliweyo zeerminal
Ukhuseleko lwakhe nabani na onokudibana ne-transformer, imimiselo ifuna ukuba zonke iitheminali zibekwe kwindawo ekungafikelelekiyo kuyo. Ukongezelela, ngaphandle kokuba i-bushings ilinganiswe ukusetyenziswa kwangaphandle-njengeebhubhu eziphezulu eziphakamileyo-kufuneka zivalwe. Ukugqunywa kwamatyholo esikhululo kugcina amanzi kunye nobutyobo kude nezinto eziphilayo. Ezona ntlobo zintathu zixhaphakileyo zokuvaleka kwesikhululo esincinci yiflange, umqala, kunye negumbi letheminali yomoya.
I-Flange
Iiflange zidla ngokusetyenziswa njengecandelo lokukhwelana nje kwibholiti kwigumbi letheminali yomoya okanye kwelinye icandelo lenguqu. Njengoko kuboniswe ngezantsi, i-transformer inokuxhotyiswa nge-flange yobude obupheleleyo (ngasekhohlo) okanye i-flange yobude obuyinxenye (ekunene), ebonelela nge-interface onokuthi uyibophe kuyo nayiphi na icandelo lenguqu okanye i-duct yebhasi.
Umqala
Umqala ngokusisiseko yiflange eyandisiweyo, kwaye njengoko ubona kulo mfanekiso ungezantsi, unokuqhagamshela ngokuthe ngqo kumjelo webhasi okanye isiqwenga sokutshintsha, njengeflange. Imiqala ihlala ibekwe kwicala le-low-voltage ye-transformer. Ezi zisetyenziswa xa ufuna ukudibanisa ibhasi enzima ngqo kwi-spades.
