I-FZN21FZNR21-12 Ukutshintsha komthwalo

Umfanekiso

I-FZN21FZNR21-12 Ukutshintsha komthwalo

I-FZ (R) N21-12d Indoor ye-MV ye-Indoor ye-MV, isetyenziselwa i-50hz yesekethe, esetyenzisiweyo ye-12hz, i-Intern Linter I-12kv, idlala isibonelelo sombane. Inokutshintsha umphuli wesekethe obizayo kuluhlu oluthile, ngaloo ndlela ukonga iindleko zotyalo mali lwamandla. Ukudityaniswa kwezixhobo zombane kunokusetyenziswa ngokubanzi kwinkqubo yeNethiwekhi yeNethiwekhi nakwiindawo ezisemaphandleni. Under normal operation condition, it can close, bear and break rated current, also can break the specified short-circuit current under abnormal conditions, especially suitable for the control and distribution and protection of transformer.

Ukhetho

Iimeko zokusebenza

I-1. I-Aldat: Akukho ngaphezulu kwe-1000m;

2. Iqondo lokusingqongileyo yendalo: umda ophezulu + 40 ℃, umda ongezantsi -30 ℃;

3. I-thedivity ye-theidity: Ixabiso lemihla ngemihla alikho ngaphezulu kwe-95%, umndilili wenyanga akaphezulu kwe-90%;

4. I-Steam Steam Steam: Ixabiso lemihla ngemihla lingaphezulu kwe-2,2 × 10 -3 Mpa, i-avareji yenyanga ayiphezulu kwe-1.8 × 10 -3 MPA;

5. Akukho ntshukumo inzima, akukho gesi ebonakalayo, akukho mlilo, akukho ndawo yengozi yokuqhushumba.
