Cov tshuab hluav taws xob yog rated nyob rau hauv kVA vim nws yog qhov loj ntawm winding tam sim no uas heats lub windings thiab yog qhov limiting yam. Cov theem kev sib raug zoo ntawm qhov voltage thiab tam sim no (lub hwj chim factor) tsis muaj feem xyuam rau qhov cua kub no.

Ib yam li ntawd ib tug yuav nug, yog vim li cas generators thiab transformers nyob rau hauv kVA?

Vim li no pom meej zog ntsuas hauv kVA ua suav tias yog cov ntsuas lub zog ntawm lub alternator. Cov tuam txhab tseem ceeb xav txog thaum tsim cov khoom siv hluav taws xob thiab cov khoom siv uas muab hluav taws xob zoo li transformer , UPS, alternators thiab cov tshuab hluav taws xob , thiab lwm yam areload thiab fais fab.

Tsis tas li ntawd, yog vim li cas alternators nyob rau hauv kVA thiab tsis nyob rau hauv kW? yog vim li cas kev ntaus nqi yog nyob rau hauv kva . cu poob ntawm transformer / alternator nyob ntawm tam sim no thiab hlau poob onvoltage. Li no tag nrho cov poob nyob ntawm volt-ampere (VA) thiab tsis yog theem lub kaum sab xis ntawm qhov voltage thiab tam sim no uas txhais tau hais tias nws tsis nyob ntawm qhov khoom siv hluav taws xob. Yog vim li cas kev ntaus nqi ntawm transformer / alternator yog nyob rau hauv KVA and not inKW.

Ntawm no, kVA txhais li cas ntawm lub tshuab hluav taws xob?

Glossary Term: kVA txhais . Lub volt-ampere (VA) yog qhov voltagetimes tam sim no pub rau hluav taws xob load. Ib kilovolt-ampere ( kVA ua ) yog 1000 volt-amperes. Lub zog hluav taws xob yog ntsuas inwatts (W): Lub sijhawm voltage ntsuas tam sim no txhua zaus.

Vim li cas peb thiaj siv kVA hloov kW?

Copper losses (I²R) nyob ntawm qhov tam sim no uas dhau los ntawm transformer winding thaum Hlau losses lossis corelosses lossis rwb thaiv tsev poob nyob ntawm qhov Voltage. Tias yog vim li cas qhov kev ntsuas qhov hloov pauv tuaj yeem qhia hauv VA lossis kVA ua , tsis nyob hauv Wor kW.
