Izintambo ezinama-voltage aphansi zisetshenziselwa imigqa engenayo nephumayo yebhokisi lokusabalalisa, futhi ukukhethwa kwezintambo kufanele kuhlangabezane nezidingo zobuchwepheshe.Isibonelo, ama-30kVA kanye nama-50kVA ama-transformer asebenzisa izintambo ze-VV22-35×4 kumugqa ongenayo webhokisi lokusabalalisa, futhi izintambo ze-VLV22-35×4 zokucaciswa okufanayo zisetshenziselwa ukuphuma kwegatsha;i-VK22-50 isetshenziselwa izintambo ezingenayo zamabhokisi okusabalalisa ama-transformer angu-80kVA no-100kVA ×4, VV22-70×4 izintambo, i-VLV22-50×4 ne-VLV22-70×4 izintambo zisetshenziselwa izitolo ze-shunt ngokulandelana, futhi izintambo ziboshwe ekhaleni lezintambo zethusi ne-aluminium, bese zixhunywa kumakhanda enqwaba yezintambo ebhokisini lokusabalalisa elinamabhawudi.
Ukukhethwa kwamafuse (RT, uhlobo lwe-NT).Isilinganiso samanje sengqikithi yokuvikela i-overcurrent fuse yohlangothi lwe-voltage ephansi ye-transformer yokusabalalisa kufanele ibe nkulu kunesilinganiso samanje sehlangothini le-low-voltage ye-transformer yokusabalalisa, ngokuvamile izikhathi ezingu-1.5 zamanje ezilinganiselwe.Isilinganiso samanje sokuncibilika kufanele sihambisane nokulayishwa okuvunyelwe okuningi kanye ne-fuse ye-transformer Izici zedivayisi zinqunywa.Isilinganiso samanje sokuncibilika kwefuse yokuvikela i-overcurrent yesiyingi esiphumayo akufanele sibe sikhulu kunomthamo wamanje olinganiselwe wengqikithi yefuse yokuvikela i-overcurrent.Isilinganiso samanje sokuncibilika sikhethwa ngokuya ngobukhulu obujwayelekile bomthwalo wamanje wesekethe futhi kufanele sigweme umthamo ovamile wamanje.
Ukuze uhlaziye amandla asebenzayo egridi yamandla e-low-voltage yasemaphandleni, faka uchungechunge lwe-DTS (X) lwemitha yamandla esebenzayo neyodwa esebenzayo kabili kweyodwa (efakwe eceleni kwebhodi lemitha) yemitha ezoshintsha. amamitha wamandla kagesi wesigaba esisodwa Ezintathu (amamitha ochungechunge lwe-DD862) ukuze kube lula ukuqapha ukusebenza kwe-inthanethi komthwalo.
