I-transformer ihambelana njani ne-breaker circuit?

Umzekelo,i-transformer yamandla ibe yi-2000kVA, kunye ne-impedance voltage Uk=6%.I-voltage elinganisiweyo ye-low-voltage side winding yi-400V / 230V (i-voltage yomgca / i-voltage yesigaba).

Inyathelo 1: Bala ireyithi yangoku yesiguquli samandla

Inyathelo lesi-2: Bala i-short-circuit current ye-transformer yamandla

Inyathelo 3: Ukuzikhethela i-breaker circuit

Ireyithi yangoku i-Ie ye-breaker circuit kufuneka ibe mkhulu kune-current rated In ye-transformer yamandla, kunye neyona ndlela yokugqibela i-short-circuit breaking capacity Icu ye-breaker circuit kufuneka ibe mkhulu kunomsinga omfutshane we-transformer yamandla.

Inyathelo 4: Misela inani leepali ze-breaker circuit

Inani leepali zomqhekezi wesiphaluka lihambelana nefom yokumisa inethiwekhi yokusabalalisa i-low-voltage.Ukuba yinkqubo ye-TN-C yokumisa, i-circuit breaker kufuneka isebenzise i-3P;ukuba ifom yokumisa inethiwekhi yokusabalalisa i-low-voltage yi-TN-S okanye i-TT, i-4P ingasetyenziswa.

Yueqing AiSo ngumvelisi oqeqeshiweyo wee-transformers kunye ne-circuit breakers.Iimveliso zikumgangatho olungileyo kunye nexabiso elihle, kwaye zithengiswa kakuhle kumazwe aphesheya kolwandle.
