Qhov kev hloov pauv ntawm lub tshuab hloov pauv yog hais txog qhov sib piv ntawm qhov siab voltage sab winding thiab qis voltage sab winding ntawm transformer. Tshwj xeeb, nws sawv cev rau qhov piv ntawm qhov ntsuas hluav taws xob nyob rau sab xub ntiag mus rau qhov ntsuas hluav taws xob nyob rau sab thib ob.
Kev ua lej, qhov hloov pauv hloov pauv (K) tuaj yeem qhia tau tias: K=ntsuas qhov hluav taws xob ntawm qhov hluav taws xob siab sab / ntsuas qhov hluav taws xob ntawm qhov hluav taws xob tsawg.
Yuav ua li cas xam transformer transformation ratio? Muaj ntau txoj hauv kev:
1.ratio=tus naj npawb ntawm cov lem nyob rau hauv thawj windings / tus naj npawb ntawm lem nyob rau hauv lub thib ob windings;
2.ratio=input voltage / output voltage
3.ratio=√(rated peev xwm ntawm lub transformer × input voltage) / tso zis voltage
Thiab hauv qab no yog qhov cuam tshuam ntawm kev hloov pauv hloov pauv ntawm lub zog hluav taws xob:
1.Voltage stability Hloov pauv hloov pauv hloov pauv yuav cuam tshuam ncaj qha rau qhov kev ruaj ntseg ntawm lub zog hluav taws xob. Tshwj xeeb, qhov nce ntawm qhov sib piv ua rau qhov nce ntawm qhov voltage, thaum qhov kev txo qis hauv qhov piv ua rau txo qis hauv qhov voltage. Hauv kev xyaum, qhov sib txawv ntawm qhov sib piv yuav tsum tau ua tib zoo tswj kom ntseeg tau tias qhov hluav taws xob ruaj khov ntawm qhov system yog nyob rau hauv qhov kev siv tau.
2. Kev hloov pauv ntawm transformer piv kuj tseem yuav cuam tshuam rau kev sib kis ntawm lub cev. Thaum qhov kev hloov pauv hloov pauv, qhov ntsuas tam sim no ntawm lub converter kuj raug txo, uas tuaj yeem ua rau txo qis hauv kev thauj khoom. Nyob rau tib lub sijhawm, lub zog reactive ntawm lub kaw lus tseem yuav cuam tshuam los ntawm kev hloov pauv hloov pauv. Yog li ntawd, thaum kho qhov kev hloov pauv, qhov cuam tshuam ntawm kev sib kis muaj peev xwm yuav tsum tau txiav txim siab tag nrho.
3.Transformers feem ntau raug mob siv hlau cores hauv lub tshuab fais fab. Kev hloov pauv hloov pauv yuav tsum tau hloov kho tag nrho cov flux ntawm cov tub ntxhais. Yog tias cov cuab yeej siv tsis tau zoo, nws yuav ua rau cov tub ntxhais hlau hlau nplaum, yog li ua rau muaj kev nyab xeeb. 4. Hauv qee qhov xwm txheej tshwj xeeb, xws li kev tshuaj xyuas thiab kev saib xyuas cov tshuab hluav taws xob thaum lub sij hawm tsim kho, tej zaum yuav tsim nyog los hloov qhov sib piv ntawm transformer kom ntseeg tau tias kev ua haujlwm zoo ntawm lub cev. Txawm li cas los xij, qhov no tseem yuav tsum tau ua tib zoo xav txog qhov cuam tshuam ntawm kev hloov pauv ntawm kev ruaj ntseg thiab kev nyab xeeb ntawm lub zog tag nrho.
