Isishwankathelo

I-ZN73-12 series indoor handcart-type high-voltage vacuum circuit breaker yi-switchgear yangaphakathi enezigaba ezintathu ze-AC 50Hz kunye nombane olinganisiweyo we-12kV.Ingasetyenziselwa ukulawula kunye nokukhuselwa kwamashishini kunye nemigodi, amashishini ombane, izitishi ezincinci, kunye nezibonelelo zombane, kwaye ifanelekile kwiindawo eziqhutywa rhoqo.Indlela yokusebenza idityaniswe kunye nomzimba we-circuit breaker, kwaye uyilo lunokusetyenziswa njengeyunithi yokufakela esisigxina, okanye inokuxhotyiswa ngesixhobo esikhethekileyo sokuqhubela phambili ukwenza iyunithi yenqwelo yesandla.Inxalenye yesekethe ephambili inokusebenzisa isibonda esiqinileyo esitywiniweyo ukuze siqonde i-miniaturization, ukuthembeka okuphezulu kunye nokugcinwa ngaphandle kwe-breaker circuit.

Imiqathango yokusetyenziswa eqhelekileyo

◆ Ubushushu be-Ambient: abukho ngaphezu kwe-40 ℃, hayi ngaphantsi kwe -10 ℃ (ukugcinwa kunye nokuthutha kwi -30 ℃ kuvunyelwe).
◆Ukuphakama: akukho ngaphezu kwe-1000m.(Ukuba i-altitude ifuna ukwandiswa, inqanaba lokugquma elilinganisiweyo liya kongezwa ngokufanelekileyo)
◆ Ukufuma okuhambelanayo: umyinge wemihla ngemihla awukho ngaphezu kwe-95%, umyinge wemihla ngemihla woxinzelelo lomphunga ogcweleyo yi-MPa, kwaye umyinge wenyanga awukho ngaphezu kwe-1.8 × 10.
◆ Ubunzulu benyikima: hayi ngaphezulu kwe-8.
◆Indawo engenamlilo, ugqabhuko-dubulo, ungcoliseko olukhulu, umhlwa weekhemikhali kunye nokungcangcazela okukhulu.
