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 ukuba isetyenziswe ngaphandle-njengamahlahla aphezulu-kufuneka ifakwe. Ukugqunywa kwamatyholo esikhululo kugcina amanzi kunye nobutyobo kude nezinto eziphilayo. Ezona ntlobo zintathu zixhaphakileyo zeendawo ezivaliweyo zesikhululo esincinci yiflange, umqala, kunye negumbi letheminali yomoya.
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 kumbhobho webhasi okanye isiqwenga sokutshintsha, njengeflange. Imiqala ihlala ibekwe kwicala le-low-voltage ye-transformer. Ezi zisetyenziswa xa ufuna ukudibanisa ibhasi enzima ngqo kwi-spades.
Umqala
Umqala ngokusisiseko yiflange eyandisiweyo, kwaye njengoko ubona kulo mfanekiso ungezantsi, unokuqhagamshela ngokuthe ngqo kumbhobho webhasi okanye isiqwenga sokutshintsha, njengeflange. Imiqala ihlala ibekwe kwicala le-low-voltage ye-transformer. Ezi zisetyenziswa xa ufuna ukudibanisa ibhasi enzima ngqo kwi-spades.
