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.
Izigaba
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.
