Kev nyab xeeb kev ua haujlwm ntawm transformers nyob rau hauv parallel yuav tsum ua raws li cov hauv qab no. Yog tias tsis ua raws li cov xwm txheej, kev ua haujlwm sib npaug yuav ua rau muaj kev nyab xeeb. Thaum tsis muaj load yuav tsum tau, yuav tsum tsis muaj kev ncig ntawm lub parallel coils. Thaum loaded, lub load ntawm txhua transformer yuav tsum tau muab faib ua feem rau lub peev xwm, thiaj li hais tias lub peev xwm yuav siv tau tag nrho.
1. Tib pab pawg sib txuas
Yog tias ob lub tshuab hluav taws xob sib txawv ntawm cov kab hluav taws xob sib txuas sib txuas ua ke, yuav muaj qhov sib txawv ntawm qhov hluav taws xob ntau hauv lub voj voog thib ob. Vim hais tias lub internal kuj ntawm lub transformer yog heev me me, nws yuav tsim ob peb lub sij hawm qhov ntsuas tam sim no, uas yuav hlawv lub transformer.
2, qhov voltage piv yog sib npaug.
Yog tias ob lub tshuab hloov pauv nrog qhov sib txawv sib txawv tau txuas nrog rau qhov sib npaug, qhov thib ob sab yuav tsim kev ncig, ua kom poob thiab muaj peev xwm. Nws tuaj yeem khiav hauv parallel yam tsis muaj overloading ib qho. Txhawm rau ua kom lub tshuab hluav taws xob sib xyaw ua haujlwm muaj kev nyab xeeb, Tuam Tshoj tau hais tias qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov hloov pauv yuav tsum tsis pub tshaj ±0.5% (hais txog cov ntaub ntawv uas tus kais hloov pauv tau muab tso rau hauv tib lub iav).
3, impedance voltage feem pua sib npaug
Yog hais tias lub impedance voltage (luv Circuit Court voltage) ntawm ob transformers tsis sib npaug, lub load nqa los ntawm lub transformer yuav tsis muab faib nyob rau hauv feem rau lub transformer muaj peev xwm. Piv txwv li, yog hais tias ib tug transformer nrog ib tug loj feem pua ntawm cov voltage yog tag nrho loaded, ib tug transformer nrog ib tug me me feem pua ntawm voltage yuav overloaded. Tsuas yog thaum twg cov transformer khiav hauv parallel tsis thauj khoom, nws tuaj yeem khiav hauv parallel.
Nws yog feem ntau ntseeg hais tias lub luv luv-circuit impedance txawv ntawm ib tug parallel transformer yuav tsum tsis txhob ntau tshaj ± 10%. Feem ntau, peb yuav tsum sim ua kom qhov voltage ntawm qhov thib ob winding ntawm lub transformer nrog loj luv luv Circuit Court impedance los yog hloov lub kais ntawm lub transformer los kho qhov luv luv Circuit Court impedance ntawm lub transformer, thiaj li hais tias lub peev xwm ntawm transformer khiav nyob rau hauv parallel. siv tag nrho.
4. Muaj peev xwm sib piv yuav tsum tsis pub tshaj 3: 1
Qhov no txwv covtransformerluv Circuit Court voltage txawv yog loj heev. Vim qhov sib txawv loj hauv impedance qhov tseem ceeb ntawm transformers nrog txawv peev xwm, lub load faib yog unbalanced, thiab los ntawm lub lag luam point of view, lub me me-capacity transformer tsis tuaj yeem ua lub luag haujlwm standby, yog li qhov muaj peev xwm sib piv yuav tsum tsis pub tshaj 3: 1. . Txawm li cas los xij, thaum ob qho kev hloov pauv tsis pub dhau qhov kev ntsuas kev ua haujlwm, lub peev xwm piv tau ntau dua 3: 1.
