Kev lag luam khaws cia hluav taws xob yog ib feem tseem ceeb ntawm lub zog niaj hnub no. Lub inverter ua ntau lub luag haujlwm hauv lub zog niaj hnub no, suav nrog kev hloov pauv hluav taws xob, kev tswj hwm thiab kev sib txuas lus, kev tiv thaiv kev cais tawm, kev tswj hwm hluav taws xob, kev them thiab tso tawm ob txoj kev, kev tswj hwm ntse, kev tiv thaiv ntau yam thiab kev sib raug zoo, uas ua rau lub inverter yog ib qho ntawm cov khoom tseem ceeb ntawm lub zog khaws cia.
Cov inverters khaws cia zog feem ntau yog tsim los ntawm cov input, output thiab control systems. Cov capacitors ua lub luag haujlwm hauv inverter, suav nrog kev ruaj khov voltage thiab filtering, khaws cia zog thiab tso tawm, txhim kho lub zog fais fab, kev tiv thaiv thiab smoothing DC pulsation. Cov haujlwm no ua ke ua kom ntseeg tau tias inverter ua haujlwm ruaj khov thiab ua haujlwm tau zoo. Rau cov system khaws cia zog, nws tuaj yeem txhim kho tag nrho cov kev ua haujlwm zoo thiab ruaj khov ntawm lub system.
Cov txiaj ntsig ntawm YMIN capacitors hauv inverters
Muaj peev xwm ceev ceev:
Lub inverter txais hluav taws xob uas tsim los ntawm cov khoom siv hluav taws xob rov ua dua tshiab xws li cov vaj huam sib luag hnub ci lossis cov cua turbines thiab hloov nws mus ua ib hom hluav taws xob uas ua tau raws li qhov xav tau. Hauv cov txheej txheem no, vim tias tam sim no load tuaj yeem nce tam sim ntawd, lub inverter yuav tsum muaj peev xwm tswj hwm lub zog kom ntseeg tau tias cov hluav taws xob tso tawm tau zoo.
YMIN txhuas electrolytic capacitorsmuaj qhov zoo ntawm qhov muaj peev xwm loj, uas tuaj yeem khaws cia ntau dua hauv tib lub ntim, ua tau raws li qhov xav tau ntawm cov khoom thauj tam sim no uas yuav nce ntxiv tam sim ntawd. Hauv kev ua haujlwm ntawm lub inverter, qhov no ua kom ntseeg tau tias cov zis hluav taws xob du.
Kev tiv thaiv tam sim no siab heev:
Thaum lub sijhawm ua haujlwm ntawm lub inverter, yog tias tsis kho qhov fais fab, qhov tam sim no ntawm nws cov zis yuav muaj ntau yam khoom sib xws. YMIN txhuas electrolytic capacitors, nrog lawv cov kev tsis sib xws sib npaug (ESR) qis thiab cov yam ntxwv zoo heev, tuaj yeem txo cov ntsiab lus sib xws, tsis yog tsuas yog ua tau raws li qhov xav tau ntawm lub nra hnyav rau lub zog AC zoo, tab sis kuj ua kom ntseeg tau tias lub inverter ua raws li cov qauv tsim nyog rau kev nkag mus rau hauv grid, txo kev cuam tshuam thiab kev cuam tshuam tsis zoo rau lub grid.
Ntxiv mus, ntawm sab DC input ntawm lub inverter, YMIN capacitors, nrog lawv cov capacitance siab thiab kev ua haujlwm zoo heev, tuaj yeem lim cov suab nrov thiab kev cuam tshuam hauv lub zog DC input, kom ntseeg tau tias cov input tam sim no huv dua, yog li txo qhov cuam tshuam ntawm cov teeb liab cuam tshuam rau cov ntu tom ntej ntawm lub inverter circuit thiab txhim kho kev ruaj khov thiab kev ua haujlwm zoo ntawm lub system.
Qhov zoo ntawm kev tiv thaiv hluav taws xob siab:
Vim muaj kev hloov pauv ntawm lub teeb ci, qhov hluav taws xob tso zis ntawm lub photovoltaic system yuav tsis ruaj khov, thiab cov khoom siv hluav taws xob semiconductor hauv lub inverter kuj tseem yuav tsim hluav taws xob thiab tam sim no nce siab thaum lub sijhawm hloov pauv. Cov kev nce siab no yuav ua rau cov khoom siv hluav taws xob puas tsuaj. Yog li ntawd, lub buffer capacitor ua lub luag haujlwm tseem ceeb hauv kev nqus hluav taws xob thiab tam sim no nce siab thiab tiv thaiv cov khoom siv hluav taws xob los ntawm hluav taws xob ntau dhau lossis kev poob siab tam sim no. Tib lub sijhawm, lub capacitor tuaj yeem ua kom cov kev hloov pauv ntawm hluav taws xob thiab tam sim no du, txo qhov poob zog thaum lub sijhawm hloov pauv, thiab yog li txhim kho kev hloov pauv zoo thiab kev ruaj khov ntawm lub inverter.
YMINCov lus qhia xaiv capacitor hauv inverter:
Sau luv luv:
Cov capacitors YMINtau txhim kho kev ua tau zoo ntawm cov inverters hauv cov tshuab khaws cia hluav taws xob nrog lawv cov yam ntxwv zoo xws li kev tiv thaiv hluav taws xob siab, lub peev xwm loj, ESR qis, thiab muaj zog ripple tam sim no tsis kam. Nws tsis tsuas yog txo qhov poob hauv cov txheej txheem hloov pauv hluav taws xob los ntawm kev lim dej zoo heev thiab cov yam ntxwv tswj hluav taws xob, tab sis kuj tuaj yeem kho qhov hluav taws xob, tam sim no thiab zaus kom ntseeg tau tias cov zis ntawm lub kaw lus txhim khu kev qha dua. Tib lub sijhawm, cov capacitors sai sai nqus cov kev co transient thiab cov suab nrov du, txhim kho lub kaw lus tiv thaiv kev cuam tshuam thiab kev ruaj khov. Tsis tas li ntawd, YMIN capacitors txhawb nqa kev khaws cia hluav taws xob thiab tso tawm thaum lub sijhawm them thiab tso tawm, ua kom muaj kev siv hluav taws xob zoo tshaj plaws ntawm lub kaw lus khaws cia hluav taws xob thiab pab tag nrho lub kaw lus ua tiav kev hloov pauv siab dua, kev ruaj khov muaj zog dua, thiab kev poob hluav taws xob qis dua.
