Khoom Taw Qhia
Hnub ci transformer yog cov khoom siv hluav taws xob tseem ceeb tsim tshwj xeeb rau lub hnub ci hluav taws xob tsim hluav taws xob. Nws hloov qhov qis -voltage AC fais fab tso zis los ntawm inverter mus rau hauv nruab nrab thiab siab -voltage AC fais fab mov haum rau kab sib txuas lossis ntev - kis tau tus mob, txhawm rau txo cov kab poob, txhim kho kev sib kis tau zoo, thiab ua tiav hluav taws xob cais tawm ntawm daim phiaj hluav taws xob, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm lub kaw lus.
Core Functions thiab Txoj Cai Ua Haujlwm
Lub luag haujlwm tseem ceeb ntawm lub hnub ci transformer yog voltage boosting. Hnub ci vaj huam sib luag tsim qis-voltage direct tam sim no (DC), uas yog hloov mus rau alternating tam sim no (AC) los ntawm ib tug inverter.
- Voltage Boosting: Qhov hluav taws xob tsis tshua muaj hluav taws xob ncaj qha tam sim no (DC) tsim los ntawm cov hnub ci vaj huam sib luag, feem ntau ntawm 400V thiab 1000V, tsis haum rau kev xa mus ntev -. Nws yog hloov mus rau hauv alternating tam sim no (AC) ntawm 11kV, 33kV, los yog ntau dua los ntawm ib tug inverter kom tau raws li daim phiaj siv cov qauv thiab ua tau ntev -nyob deb, tsis tshua muaj kis tau tus mob thiab muaj kev ruaj ntseg kab sib txuas ntawm hluav taws xob hluav taws xob.
- Kev sib cais hluav taws xob: ua kom muaj kev sib cais ntawm lub cev ntawm lub photovoltaic system sab (thawj sab) thiab daim phiaj sab (thib ob), tiv thaiv qhov hluav taws xob rov qab los yog txhaum tam sim no rov qab rau hauv daim phiaj, thiab tiv thaiv kev nyab xeeb ntawm cov khoom siv tseem ceeb xws li inverters thiab roj teeb.
- Kev ua kom zoo ntawm lub zog zoo: Tshem tawm 3rd, 5th, thiab 7th harmonics generated los ntawm inverters (tag nrho cov harmonic distortion tuaj yeem ncav cuag 8% -15%), txo cov pa phem rau hauv daim phiaj fais fab, thiab xyuas kom cov kab sib txuas hluav taws xob ua tau raws li lub teb chaws tus qauv.
- Kev hloov kho thiab kev txhawb nqa ruaj khov: sib piv cov yam ntxwv hloov pauv ntawm cov khoom siv hluav taws xob photovoltaic, muaj peev xwm ua tau zoo (muaj peev xwm tiv taus luv luv - lub sij hawm thauj khoom ntawm 110% -120%), yoog mus rau qhov tsis tshua muaj hluav taws xob hloov pauv los ntawm kev hloov hauv teeb pom kev zoo, thiab ua kom muaj kev ruaj ntseg ntawm lub kaw lus.
- Lub hauv paus ntsiab lus ua haujlwm: Lub tshuab hloov hluav taws xob muaj cov tub ntxhais hlau kaw thiab ob lub qhov hluav taws xob insulated: thawj winding yog txuas nrog qis -voltage fais fab mov, thiab qhov thib ob winding outputs siab -voltage hluav taws xob lub zog.
- Raws li Faraday txoj cai ntawm electromagnetic induction, qhov voltage tuaj yeem ua kom muaj zog los ntawm kev kho qhov sib piv ntawm thawj thiab theem nrab windings.
- Lub zog yog kis los ntawm kev sib nqus teb sib txuas yam tsis muaj kev sib txuas hluav taws xob ncaj qha, ua tiav ob txoj haujlwm ntawm kev hloov pauv hluav taws xob thiab kev sib cais hluav taws xob.
