Hlau poob thiab tooj liab poob tshwm sim nyob rau hauv lub transformer tseem muaj kev ywj pheej ntawm lub hwj chim. Hloov pauv yog rated nyob rau hauv kVA vim txoj kev lossesoccurring nyob rau hauv transformers yog ywj siab ntawm powerfactor. KVA yog lub zog uas pom tseeb. Nws yog acombination ntawm lub hwj chim tiag tiag thiab reactive zog.

Ib yam li ntawd, tib neeg nug, yog vim li cas transformers nyob rau hauv kVA thiab tsis nyob rau hauv kW?

Kev poob tooj liab (I²R) nyob ntawm qhov tam sim no uas dhau mus transformer winding thaum Iron losses orcore poob los yog rwb thaiv tsev poob nyob ntawm qhov Voltage. Yog vim li cas tus transformer ntsuas tej zaum yuav qhia nyob rau hauv VA los yog kVA ua , tsis yog hauv W lub kW.

Vim li cas transformers nyob hauv MVA? Cov tooj liab poob hauv lub transformer yog variable losses thiab yog nyob ntawm qhov tam sim no kev ntaus nqi ntawm transformer thiab cov hlau poob yog nyob ntawm qhov voltage. Yog li ntawd, tag nrho cov poob hauv a transformer nyob ntawm qhov voltage thiab tam sim no kev ntaus nqi ntawm transformer.

Tsis tas li ntawd, vim li cas qhov ntsuas qhov ntsuas hluav taws xob hauv kVA?

Nws nce vim kev poob. Losses uas tshwm sim hauv transformer nce lawv qhov kub thiab txias. Yog li, peb tuaj yeem hais tias lub kev ntaus nqi ntawm transformer yog nyob rau hauv KVA.

Vim li cas transformers ntsuas VA?

Cov VA rating yog siv los xaiv lub fuse kom raug rau qhov Circuit Court. Lub fuse yuav tsum me dua li qhov VA rating ntawm transformer . Qhov no yuav txiav txim siab qhov siab tshaj plaws load uas tuaj yeem txuas nrog transformer . Cias muab, lub VA rating yog lub mathformula siv los txiav txim qhov amperage ntawm ib qho voltage.
