Yuav ua li cas xam Transformer Efficiency

Transformer efficiency yog hais txog qhov piv ntawm cov zis hluav taws xob ntawm lub transformer mus rau lub zog input, uas yog, lub zog conversion efficiency ntawm lub transformer. Feem ntau nws tuaj yeem muab faib ua ob hom: theoretical efficiency thiab kev ua haujlwm zoo.

1. Theoretical efficiency
Theoretical efficiency, tseem hu ua 100% efficiency, yog hais txog tus piv ntawm transformer tso zis hwj chim rau input zog yam tsis poob, uas yuav xam tau los ntawm cov nram qab no mis:
Theoretical efficiency=tso zis zog ÷ input zog × 100%
qhov twg cov zis hluav taws xob thiab lub zog input yog cov khoom ntawm cov zis voltage thiab tam sim no ntawm transformer thiab input voltage thiab tam sim no, feem.

2. Kev ua tau zoo tiag tiag
Kev ua tau zoo tiag tiag yog hais txog kev ua haujlwm ntawm lub tshuab hluav taws xob tom qab suav nrog lub zog poob hauv kev ua haujlwm tiag tiag. Muaj ntau ntau hom hluav taws xob poob hauv transformers, xws li hlau poob, tooj liab poob, thiab lwm yam., yog li cov qauv rau kev xam qhov tseeb efficiency yog complex, thiab feem ntau yog xam los ntawm cov qauv hauv qab no:
Kev ua tau zoo tiag tiag=tso zis hluav taws xob ÷ (lub zog nkag + tag nrho poob) × 100%
Qhov poob tag nrho yog qhov hluav taws xob poob ntawm lub transformer thaum lub sijhawm ua haujlwm, uas tuaj yeem tau txais los ntawm kev sim lossis cov ntaub ntawv muab los ntawm cov chaw tsim khoom.
