(1) Isikali sesikhululo sokutshaja esiqhelekileyo
Ngokutsho kwedatha yangoku yokutshaja okuqhelekileyo kwezithuthi zombane, isikhululo sokutshaja silungiselelwe ngokubanzi kunye ne-20 ukuya kwi-40 yezithuthi zombane.Olu lungelelwaniso kukuqwalasela ukusebenzisa ngokupheleleyo umbane wentlambo yangokuhlwa ukutshaja, kodwa into embi kukuba izinga lokusetyenziswa kwezixhobo zokutshaja liphantsi.Ukutshaja kwakhona kuqwalaselwa ngexesha leeyure eziphakamileyo, kwaye isikhululo sokutshaja sinokuqulunqwa kwi-60-80 izithuthi zombane.Ukungalungi kukuba ixabiso lokutshaja liyenyuka kwaye umthwalo ophakamileyo uyanyuswa.
(2) Ulungelelwaniso oluqhelekileyo lonikezelo lombane lwesikhululo sokutshaja (ngaphandle kokuba ikhabhinethi yokutshaja inemisebenzi yokucubungula efana neeharmonics)
ISkimu a: Ukwakha isikhululo sokuhambisa umbane, yila amajelo ama-2 eentambo ezingenayo eziyi-10KV (ezineentambo eziyi-3*70mm), iiseti ezi-2 ze-500KVA yesiguquli, kunye namajelo angama-24 eentambo eziphumayo ezingama-380V.Ezimbini kuzo zinikezelwe ukutshaja okukhawulezayo (nge-4 * 120mm intambo, 50M ubude, iilophu ezi-4), enye yeyokutshaja ngoomatshini okanye i-backup, kwaye ezinye ziyimigca yokutshaja eqhelekileyo (enentambo eyi-4 * 70mm, i-50M ubude, iilophu ezingama-20 )
Scheme b: Yila iitshaneli ezi-2 zeentambo ze-10KV (ezineentambo ze-3 * 70mm), misela iiseti ezi-2 ze-500KVA yebhokisi yomsebenzisi ye-transformer, ibhokisi nganye ye-transformer ixhotyiswe ngeentambo ezi-4 ze-380V zemigca ephumayo (kunye neentambo ze-4 * 240mm, i-20M ubude, i-8 iilophu), ishaneli nganye Ibhokisi yesebe ye-4-circuit cable imiselwe umgca ophumayo ukubonelela umbane kwikhabhinethi yokutshaja (nge-4 * 70mm cable, ubude be-50M, iisekethe ezingama-24).
