Muaj pes tsawg leeg thiab cov yam ntxwv ua haujlwm ntawm tam sim no transformer
Sep 13, 2023| 1. Tus naj npawb ntawm thawj lem yog me me thiab tus naj npawb ntawm qhov thib ob tig yog loj.
Rau tam sim no transformers siv nyob rau hauv lub tshuab fais fab, thawj winding feem ntau yog cov khoom nkag thiab tawm ntawm cov khoom siv thawj zaug, tsuas yog 1 lossis 2 lem; tus lej thib ob yog qhov loj.
2. Kev ua haujlwm sib nqus hauv cov tub ntxhais hlau yog qhov tsawg heev, thiab qhov sib nqus sib nqus yog siab thaum lub kaw lus tsis ua haujlwm.
Thaum lub sijhawm ua haujlwm ib txwm muaj, kev khiav hauj lwm sib nqus qhov sib nqus nyob rau hauv cov tub ntxhais ntawm tam sim no transformer yog tsawg heev, thiab nws cov theem pib thiab theem nrab tswj ampere-tig tshuav nyiaj li cas. Thaum lub kaw lus tsis ua haujlwm, vim yog qhov txhaum loj tam sim no thiab siab theem nrab voltage, qhov excitation tam sim no nce thiab qhov sib nqus ntom ntom hauv cov tub ntxhais hlau nce siab, txawm tias saturating cov tub ntxhais hlau.
3. Siab sab hauv tsis kam, tam sim no qhov chaw
Nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, lub sib nqus ceev nyob rau hauv lub hlau core yog tsawg heev, lub excitation impedance yog loj, thiab cov thib ob lem yog loj. Saib los ntawm ob sab, nws impedance loj heev. Piv nrog rau cov kev tiv thaiv sab hauv ntawm tam sim no transformer, lub load impedance yog negligible, yog li qhov kev hloov ntawm load impedance muaj me ntsis cuam tshuam rau theem nrab tam sim no, yog li nws tuaj yeem hu ua qhov tam sim no.
4. Me me theem nrab load yuav tsum
Yog hais tias qhov thib ob load ntawm tam sim no transformer loj, nws theem nrab voltage yuav siab heev thaum lub sij hawm ua hauj lwm, thiab lub excitation tam sim no yuav inevitably nce, yog li ua rau tam sim no hloov dua siab tshiab yuam kev.
5. Lub voj voog thib ob yuav tsum tsis txhob qhib
Yog tias lub voj voog thib ob qhib thaum lub sijhawm ua haujlwm, qhov thib ob tam sim no ploj mus, thiab cov nyhuv demagnetization kuj ploj mus, thiab qhov sib nqus ntawm cov hlau tseem ceeb heev; thiab vim tias muaj ntau qhov kev hloov pauv thib ob, qhov hluav taws xob theem nrab yuav siab heev, qee zaum mus txog Ntau txhiab volts, cuam tshuam cov khoom siv thib ob thiab kev nyab xeeb ntawm tus kheej.
