I-transformer ifaniswa kanjani ne-circuit breaker?

I-transformer ifaniswa kanjani ne-circuit breaker?

Ngokwesibonelo,i-transformer yamandla ibe ngu-2000kVA, kanye ne-impedance voltage Uk=6%.I-voltage elinganiselwe ye-low-voltage side winding ngu-400V/230V (i-voltage yomugqa/i-voltage yesigaba).

Isinyathelo 1: Bala isilinganiso samanje se-transformer yamandla

Isinyathelo sesi-2: Bala i-short-circuit current yesiguquli samandla

Isinyathelo sesi-3: I-breaker circuit ozikhethela yona

Isilinganiso samanje se-Ie se-circuit breaker kumele sibe sikhulu kune-current elinganisiwe ye-In ye-transformer yamandla, futhi umthamo wokugcina we-Icu we-short-circuit breaker we-circuit breaker kumele ube mkhulu kune-short-circuit current ye-transformer yamandla.

Isinyathelo sesi-4: Thola inani lezigxobo ze-breaker circuit

Inombolo yezigxobo ze-circuit breaker ihlobene nefomu eliphansi lenethiwekhi yokusabalalisa i-voltage ephansi.Uma kuwuhlelo lwe-TN-C lokumisa phansi, i-circuit breaker kufanele isebenzise i-3P;uma ifomu eliyisisekelo lenethiwekhi yokusabalalisa i-low-voltage kuyi-TN-S noma i-TT, i-4P ingasetshenziswa.

Yueqing AiSo ungumkhiqizi ochwepheshe wama-transformer nama-circuit breaker.Imikhiqizo ingeyekhwalithi enhle nenani elihle, futhi idayiswa kahle emazweni amaningi aphesheya kwezilwandle.

Siyakwamukela ukuxhumana nathi!
