Efficiency ntawm Distribution Transformer

1, Txhais ntawm Transformer Efficiency

Transformer efficiency yog hais txog qhov sib piv ntawm cov zis hluav taws xob rau cov khoom siv hluav taws xob ntawm lub tshuab hluav taws xob, thiab tuaj yeem raug xa mus rau qhov ua tau zoo ntawm kev hloov hluav taws xob hloov hluav taws xob. Cias muab, nws yog hais txog qhov kev faib ua feem ntawm lub zog poob los ntawm ib tug transformer thaum lub zog xa mus rau lub tswv yim. Feem ntau qhia raws li feem pua, cov qauv yog raws li nram no:

Transformer efficiency=(tso zis zog ÷ input zog) × 100%

Ntawm lawv, cov zis hluav taws xob yog hais txog qhov thib ob tam sim no ntawm transformer multiplied los ntawm theem nrab voltage, uas yog cov zis hluav taws xob; Input zog yog hais txog lub ntsiab tam sim no ntawm lub transformer multiplied los ntawm lub ntsiab voltage, uas yog lub input hluav taws xob hwj chim.

2, Yuav ua li cas xam Transformer Efficiency

Yuav kom xam qhov ua tau zoo ntawm lub transformer, nws yog ib qho tsim nyog yuav tsum paub lub zog tawm tswv yim thiab cov zis hluav taws xob ntawm lub transformer. Lub zog input ntawm lub transformer tuaj yeem tau txais los ntawm kev ntsuas qhov input voltage thiab tam sim no, thaum lub zog tso zis yuav tsum ntsuas cov zis voltage thiab tam sim no. Cov txheej txheem suav tshwj xeeb yog raws li hauv qab no:

1. Ntsuas lub ntsiab tam sim no thiab qhov hluav taws xob kom tau txais lub zog hluav taws xob input

Main theem tam sim no (input tam sim no) =Main theem voltage ÷ Main theem impedance

Lub zog hluav taws xob =piv txwv tam sim no × Main voltage

2. Ntsuas qhov nruab nrab tam sim no thiab qhov hluav taws xob kom tau txais cov hluav taws xob tso zis hluav taws xob

Secondary tam sim no (tso tawm tam sim no) =secondary voltage ÷ Secondary impedance

Tso zis fais fab =secondary tam sim no × Secondary voltage

3. Xam qhov ua tau zoo ntawm lub transformer

Transformer efficiency=tso zis zog ÷ input zog × 100%

3, Cov yam ntxwv cuam tshuam rau transformer efficiency

Qhov kev ua tau zoo ntawm lub transformer nyob ntawm nws tus qauv tsim thiab kev ua haujlwm tiag tiag. Cov hauv qab no yog qhov tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm transformer:

1. Tsim ntawm Transformer

Cov qauv thiab qhov ntsuas qhov ntsuas ntawm lub tshuab hloov pauv tuaj yeem cuam tshuam nws cov txiaj ntsig, xws li cov khoom siv hlau, kev tsim winding, thiab cov khoom siv rwb thaiv tsev ntawm lub tshuab hluav taws xob.

2. Load tus nqi ntawm transformer

Qhov siab dua qhov load tus nqi ntawm lub transformer, lub zog ntau dua yuav poob thiab qhov ua tau zoo yuav qis dua; Thaum qis load tus nqi, qhov ua tau zoo ntawm lub transformer yuav kuj siab.

3. Kub nce ntawm transformer

Thaum lub tshuab hluav taws xob tsim hluav taws xob ntau dua, nws yuav tsum tau dissipate cua sov, haus ntau zog, thiab qhov ua tau zoo kuj yuav txo.

4. Kab tsis kam thiab kis tau tus mob nrug

Ntev hlau thiab cable kis tau tus mob nyob deb kuj tuaj yeem ua rau txo qis kev ua haujlwm.

Nyob rau hauv luv luv, los txhim kho cov efficiency ntawm transformers, nws yog tsim nyog los pib nrog tsim, kev khiav hauj lwm, thiab txij nkawm, tsim nyog xaiv transformer tsis, txhim kho load npaum li cas, tswj kub nce thiab kuj yam tseem ceeb, thiab txhim khu lub zog kis tau tus mob efficiency.
