1. Kutheni kufuneka intsimbi engundoqo yetransformer isekelwe?
Ukufakwa kwesiseko setransformer kuxhomekeke kukhuseleko kunye nokuhambelana kwe-electromagnetic.
Kwelinye icala, ukumisa umhlaba kwi-transformer core kuthintela ii-contact voltages ezibangelwa ziimpazamo zomhlaba, ezinokubangela ingozi ebantwini. Kuba xa umhlaba uphazamile kwelinye icala le-transformer, i-iron core kwelinye icala inokuba ne-voltage edibana nomhlaba. Ukuba ayimiswanga, le voltage ayinakukhululwa.
Kwelinye icala, ukumisa umhlaba kwi-transformer core kunokunciphisa ukuphazamiseka kwemitha ye-electromagnetic, ingakumbi kwizixhobo zerediyo kunye neenkqubo zonxibelelwano. Oku kungenxa yokuba umbane uya kuvelisa i-magnetic field kwi-iron core. Ukuba i-iron core ayimi, le magnetic field inokuvuza kwindawo engqongileyo kwaye iphazamise ukusebenza okuqhelekileyo kwezinye izixhobo.
Ukuqukumbela, ukumisa isiseko se-transformer yindlela yokukhusela kwiingozi zokutshatyalaliswa kunye nokuphazamiseka kwe-electromagnetic.
