Mar 31, 2026| I. Cov Lus Qhia Tshwj Xeeb rau Zaj Duab Xis Capacitor hauv Kev Siv Hluav Taws Xob Hluav Taws Xob
Hluav taws xob cov dej rhaub dej ua haujlwm nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias, cov av noo siab, thiab kev hloov pauv tsis tu ncua. Piv nrog rau cov neeg siv khoom siv hluav taws xob siv hluav taws xob, lawv tso cov kev xav tau siab dua ntawm ib puag ncig kev kam rau siab thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob:
Kub Adaptability: Sab hauv kev khiav hauj lwm kub nyob rau hauv hluav taws xob lub rhaub dej feem ntau yog li ntawm 60℃mus rau 85 degree, nrog rau cov tub ntxhais Circuit Court cheeb tsam nyob rau hauv ib co high - fais fab qauv mus txog 100℃. Qhov no yuav tsum tau capacitors kom ruaj khov kev ua haujlwm thoob plaws qhov kub thiab txias;
Voltage Fluctuation Resistance: Voltage fluctuations nyob rau hauv cov vaj huam sib luag fais fab vaj huam sib luag feem ntau yog li ntawm ± 15%, nrog rau cov neeg laus hauv cheeb tsam muaj kev hloov pauv ntau dua. Capacitors yuav tsum muaj qhov hluav taws xob txaus kom tiv thaiv kev tawg;
Lub neej ua haujlwm ntev: Lub neej ua haujlwm ntawm lub tshuab hluav taws xob hluav taws xob yog 8-10 xyoo. Capacitors yuav tsum tsis pub dawb los ntawm kev pheej hmoo ntawm electrolyte ziab tawm, nrog rau lub sijhawm ntev - kev ua haujlwm degradation tsawg dua 5%.
II. Cov npe ntawm Cov Txheej Txheem Xaiv Cov Txheej Txheem (raws li Cov Qauv Kev Lag Luam Hauv Tsev)
Raws li cov lus qhia tshwj xeeb uas muaj nyob rau hauv cov khoom siv hluav taws xob hauv kev lag luam, xya yam hauv qab no yog qhov tseem ceeb rau nyias - zaj duab xis capacitors siv hauv hluav taws xob rhaub dej. Tag nrho cov kev ntsuas yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm kev tsim hluav taws xob:
| Lub npe Parameter | Kev xaiv yuav tsum | Daim Ntawv Thov Kev Siv Hluav Taws Xob rau Kev Siv Hluav Taws Xob Hluav Taws Xob |
| Rated Voltage | Yuav tsum yog 20% -50% siab tshaj qhov hluav taws xob ua haujlwm siab tshaj plaws; qhov tseeb ua haujlwm voltage yuav tsum tsis pub tshaj 80% ntawm tus nqi ntsuas | Rau cov qauv 220V hauv tsev, xaiv cov capacitors ntsuas ntawm 400V lossis siab dua |
| Muaj peev xwm | Yuav tsum ua raws li E24 series tus qauv tus nqi; Ua ntej cov qhab nias siab ntawm ± 5% | Rau cov ntawv thov lim, feem ntau xaiv cov capacitors hauv 0.1μF-10μF ntau yam; Cov nqi tshwj xeeb yuav tsum tau txiav txim siab raws li kev suav hauv Circuit Court |
| Rated Ripple Tam sim no | Yuav tsum yog 1.2-1.5 npaug ntau dua li qhov tseeb ripple tam sim no | Qhov tso cai kub nce rau polypropylene capacitors yog tsis ntau tshaj 5 degree, thiab tsis ntau tshaj 10℃rau polyester capacitors |
| Tangent ntawm Loss Angle | Rau siab - cov ntawv thov zaus, cov ripple tam sim no yuav tsum tsawg dua 0.1% kom txo tau tus kheej - cua sov | Ua ntej tshaj plaws polypropylene capacitors, raws li lawv cov txiaj ntsig poob qis dua li cov polyester capacitors |
| Kub yam ntxwv | Qhov kub coefficient ntawm capacitance yuav tsum tsis pub tshaj ± 200 ppm / degree, kom ntseeg tau tias qhov kev ruaj ntseg nyob rau hauv dav - qhov kub thiab txias | Hauv qhov siab - qhov kub thiab txias, ua qhov tseem ceeb ntawm cov capacitors ua los ntawm PPS lossis PP |
| Rwb thaiv tsev Resistance | Qhov kev tiv thaiv yuav tsum siab dua 10 ^ 9 Ω kom txo qhov kev pheej hmoo ntawm cov xau tam sim no | Xyuas kom meej tias tsis muaj kev pheej hmoo ntawm kev xau thaum lub sijhawm ua haujlwm ntev - |
| Hom pob | Ua ntej cov pob khoom ua ntej uas ua raws li cov qauv kev teeb tsa hauv tsev, nrog tus pin sib nrug sib piv PCB tsim cov cai | Moulded txhuas qhov sib txawv tuaj yeem kho raws li cov chaw tsim khoom xav tau |
III. Phau Ntawv Qhia Txog Kev Xaiv thiab Sib Piv Cov Khoom Siv Dielectric
Kev ua tau zoo ntawm zaj duab xis capacitors sib txawv heev nyob ntawm seb cov khoom siv dielectric siv. Kev xaiv yuav tsum yog raws li cov kev xav tau thiab kev ua haujlwm ntawm lub tshuab rhaub dej fais fab:
Polypropylene (PP/CBB) capacitors: Muab kev ua tau zoo tshaj plaws, cov capacitors no muaj qhov poob qis, zoo heev - tus yam ntxwv zaus, thiab kub kub stability. Lawv yog cov khoom ntawm kev xaiv rau lim thiab resonant circuits nyob rau hauv inverter-tsav hluav taws xob dej rhaub, yog haum rau nruab nrab- mus rau siab- qauv kawg, thiab ua kom pom qhov zoo tshaj plaws ntev - lub sij hawm cia siab rau;
Polyester (PET / CL) Capacitors: Featuring high dielectric tas li, compact loj, thiab tus nqi qis, cov no yog tsim rau kev sib txuas dav dav thiab hla Circuit Court nyob rau hauv tus qauv ruaj- zaus dej rhaub, muab cov nqi zoo tshaj -effectiveness;
Polyphenylene Sulfide (PPS) Capacitors: Nrog rau qhov kub thiab txias thiab qhov muaj peev xwm ua tau zoo, cov no tsim nyog rau kev tswj Circuit Court nyob rau hauv ntse thermostatic dej rhaub uas yuav tsum tau tsis tshua muaj siab parameter sib xws;
Polyethylene naphthalate (PEN) capacitors: Nrog rau qhov kub zoo dua li PET, lawv tsim nyog rau circuits nyob rau hauv siab - qhov kub thiab txias nyob ze ntawm cov cua sov modules.
IV. Cov kev xav tsis zoo hauv kev xaiv Capacitor thiab qhov tseem ceeb pitfalls kom zam
Raws li kev txheeb cais tsis ua haujlwm los ntawm kev lag luam kho khoom siv hauv tsev, kev xaiv tsis raug ntawm cov yeeb yaj kiab capacitors yog ib qho ntawm peb qhov ua rau kev ua haujlwm tsis zoo hauv lub tshuab hluav taws xob hluav taws xob. Peb qhov teeb meem hauv qab no yuav tsum tau ua ntej rau kev zam:
Tsis txaus voltage margin: Qee lub tuam txhab xaiv cov kev qhia tshwj xeeb nrog cov ntsuas hluav taws xob nyob ze rau qhov kev khiav hauj lwm voltage kom txo cov nqi. Qhov no ua rau kev puas tsuaj tsis zoo yuav tshwm sim thaum lub zog hluav taws xob hluav taws xob hloov pauv. Nws raug nquahu kom tswj hwm qhov voltage ntawm tsawg kawg 20%;
Tsis sib haum ripple tam sim no: Yog hais tias qhov tseeb ripple tam sim no tshaj lub capacitor tus nqi ntsuas, nws yuav ua rau nws tus kheej hnyav - cua sov. Ntev- lub sijhawm ua haujlwm ntawm qhov kub thiab txias tuaj yeem ua rau lub neej luv dua li 70%. Thaum xaiv cov capacitors, lub Circuit Court ripple tam sim no tsis yuav tsum tau txheeb xyuas los ntawm kev sim tiag tiag;
Tsim qhov tsis zoo hauv kev sib koom ua ke tam sim no: Thaum siv ntau lub capacitors nyob rau hauv parallel, kev sib txuas tsis sib xws tuaj yeem ua rau tsis sib xws tam sim no, ua rau kub kub nce hauv ib tus neeg capacitors thiab tom qab burnout. Kev xaim yuav tsum tau kho kom zoo kom ntseeg tau tias muaj kev sib koom tam sim no.
Cov kws tshuaj ntsuam xyuas hauv kev lag luam khoom siv hauv tsev tau taw qhia tias raws li kev sib tw mus rau ntse dua thiab inverter-tsav hluav taws xob lub rhaub dej ua kom nrawm, kev xaiv thiab qhov zoo ntawm zaj duab xis capacitors yuav dhau los ua ib qho tseem ceeb hauv kev ua kom ntseeg tau ntawm cov khoom tiav. Lawv pom zoo kom cov tuam txhab tsim cov khoom siv sib xyaw ua ke thiab cov txheej txheem kev siv tau thiab ua tiav - kev kuaj kev laus ua ntej kev yuav khoom ntau kom ntseeg tau ntev - cov khoom lag luam ruaj khov.
