I-ZN73-12 uchungechunge lwangaphakathi lwenqola yesandla yohlobo lwe-high-voltage vacuum circuit breaker iyisishintshi sasendlini esinezigaba ezintathu ze-AC 50Hz kanye ne-voltage elinganiselwe engu-12kV.Ingasetshenziselwa ukulawula nokuvikela amabhizinisi ezimboni nezimayini, izimboni zikagesi, iziteshi ezincane, kanye nezinsiza zikagesi, futhi ifaneleka ezindaweni ezisetshenziswa njalo.Indlela yokusebenza ihlanganiswe nomzimba we-circuit breaker, futhi idizayini ingasetshenziswa njengeyunithi yokufaka engaguquki, noma ingahlonyiswa ngendlela ekhethekile yokuqhubeza ukuze yakhe iyunithi yenqola yesandla.Ingxenye yesekethe eyinhloko ingasebenzisa isigxobo esiqinile esivalwe ngokuqinile ukuze ibone ubuncane be-miniaturization, ukwethembeka okuphezulu kanye nokungakhathali kwe-breaker circuit.

Imibandela Yokusebenzisa Okuvamile

◆ Izinga lokushisa le-ambient: alikho ngaphezu kuka-40 ℃, hhayi ngaphansi kuka -10 ℃ (isitoreji nokuhamba ku -30 ℃ kuvunyelwe).
◆Ukuphakama: akukho ngaphezu kuka-1000m.(Uma ukuphakama kudinga ukunyuswa, izinga lokufaka elilinganiselwe lizokwenyuswa ngokufanele)
◆ Umswakama ohlobene: isilinganiso sansuku zonke asikho ngaphezu kuka-95%, isilinganiso sansuku zonke sokucindezela komhwamuko ogcwele i-MPa, kanti isilinganiso sanyanga zonke asingaphezu kuka-1.8×10.
◆Ukuqina kokuzamazama komhlaba: akukho ngaphezu kuka-8.
◆Indawo engenamlilo, ukuqhuma, ukungcola okukhulu, ukugqwala kwamakhemikhali nokudlidliza okukhulu.
