Nov 28, 2025| 
I. Core Parameters: Precisely Matching Welding Equipment Requirements
Thawj kauj ruam hauv kev xaiv yog kom paub meej cov cuab yeej siv cov kev cai rau cov capacitors. Peb qhov kev txwv hauv qab no yog qhov tseem ceeb tshaj plaws:
1. Capacitance: Tsis tas yuav loj dua, zoo dua
Capacitance yog ntsuas hauv Farads (F), feem ntau hais tias μF lossis nF. Kev tshawb fawb qhia tias kev lim dej hauv cov khoom siv vuam feem ntau xav tau cov capacitors xws li 0.1μF txog 100μF. Txawm li cas los xij, kev muaj peev xwm ntau dhau tuaj yeem ua rau muaj qhov tam sim no ntau dhau, cuam tshuam nrog cov khoom pib pib; conversely, tus nqi qis dhau ua tsis tau zoo lim siab - suab nrov zaus. Piv txwv li, lub resonant Circuit Court nyob rau hauv siab - zaus welders yuav tsum tau muab xam capacitance raws li zaus kom tsis txhob dig muag nce.
2. Rated Voltage: Distinguishing DC / AC daim ntawv thov
Cov cuab yeej siv vuam yuav ua haujlwm ntawm qhov tam sim no ncaj qha (DC) lossis hloov pauv tam sim no (AC), yuav tsum tau ua kom nruj nruj nrog lub capacitor qhov ntsuas voltage hom. Cov ntaub ntawv qhia tias tus txheej txheem zaj duab xis capacitors feem ntau muaj DC qhov ntsuas txij li kaum mus rau pua pua volts, thaum lub zog- qib siab- hom hluav taws xob tuaj yeem tiv taus ntau txhiab volts. Yog tias cov cuab yeej ntsib kev pheej hmoo overvoltage, xaiv cov khoom uas muaj peev xwm tiv thaiv hluav taws xob (xws li cov qauv dhau IEC tiv thaiv qhov ntsuas hluav taws xob).
3. Rated Tam sim no: Tiv thaiv kev puas tsuaj overheating
Rated tam sim no qhia txog qhov kev nyab xeeb tshaj plaws ua haujlwm tam sim no rau cov capacitors. Kev tshawb fawb qhia tias kev tshaj qhov nqi no ua rau overheating, kev puas tsuaj hauv cheeb tsam, lossis txawm tias tawg. Cov cuab yeej siv vuam siab - zaus ua haujlwm xav tau ntau dua tam sim no. Xaiv cov khoom lag luam nrog qhov ntsuas tam sim no ** 10% -20% siab dua qhov kev ua haujlwm tam sim no ** txhawm rau txhim kho kev ntseeg tau.
II. Cov Khoom Siv Dielectric: Xaiv qhov kev daws teeb meem zoo raws li daim ntawv thov scenarios
Cov khoom siv dielectric ntawm zaj duab xis capacitors ncaj qha cuam tshuam kev ua haujlwm. Cov ntaub ntawv zoo li polyester (PET) thiab polypropylene (PP) txhua tus muaj lawv qhov zoo thiab qhov tsis zoo:
| Hom Nruab Nrab | Cov yam ntxwv tseem ceeb | Daim ntawv thov rau cov khoom siv vuam |
| Polyester (PET) | Qhov loj me, tus nqi qis, qhov kub thiab txias ntau yam (-55℃rau +120} degree), tab sis kev poob siab | Nruab nrab-rau- cov khoom siv vuam zaus tsawg (piv txwv li, phau ntawv arc vuam), tus nqi- qhov xwm txheej ceev |
| Polypropylene (PP) | Tsis tshua muaj siab siab - zaus poob (tanδ Tsawg dua lossis sib npaug li 0.1%), tus kheej muaj zog- kho muaj peev xwm, muaj kev tiv thaiv siab | High- vuam tshuab zaus (xws li laser vuam, ultrasonic vuam), siab- precision resonant circuits |
Kev tshawb fawb qhia tias tus kheej - kho cov cuab yeej ntawm polypropylene dielectric yog nws qhov txiaj ntsig tseem ceeb -thaum muaj qhov tsis xws luag hauv microscopic tshwm sim hauv dielectric, cov hlau nyob ib puag ncig lub ntsiab lus tawg evaporates kom cais qhov txhaum, rov ua haujlwm capacitive. Qhov no ua rau nws tshwj xeeb tshaj yog haum rau cov khoom siv vuam ua haujlwm nyob rau hauv ntev - lub sij hawm siab loads.
III. Zoo thiab kev ntseeg tau: Kev ua tau zoo tshaj tawm hauv cov ntsiab lus
High -cov yeeb yaj kiab zoo yuav tsum ua raws li cov qauv hauv qab no:
1. Kev ruaj ntseg hluav taws xob
Capacitance qhov tseem ceeb yuav tsum muaj qhov sib txawv me me los ntawm cov nqi ntsuas nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias (piv txwv li, polypropylene capacitors nrog kub coefficient tsawg dua lossis sib npaug rau ± 100 ppm /℃).
2. Tsawg Dissipation Factor
Qhov qis dua qhov cuam tshuam (DF) txo qis zog poob. Kev tshawb fawb qhia tias cov khoom siv soldering yuav tsum siv cov khoom siv nrog DF Tsawg dua lossis sib npaug li 0.5%, thaum siab - cov ntawv thov zaus yuav tsum tau qis dua (xws li, PP capacitors nrog DF Tsawg dua lossis sib npaug li 0.1%).
3. Ua raws li cov txheej txheem tsim khoom
Ua ntej cov tuam txhab tau ntawv pov thawj rau cov qauv thoob ntiaj teb xws li ISO 9001 thiab IEC, uas cov khoom lag luam tau dhau los ua qhov kev sim siab tiv thaiv hluav taws xob thiab kev sim siab (feem ntau ntau dua lossis sib npaug li 5000 teev).
4. Kev tiv thaiv ib puag ncig
Qhov chaw vuam tej zaum yuav muaj qhov kub thiab txias. Xaiv cov khoom nrog nruj encapsulation thiab muaj zog noo noo tsis kam (xws li epoxy resin potted qauv).
IV. Branding thiab Procurement: Xaiv cov neeg koom tes uas ntseeg siab
Kev tshawb fawb pom zoo kom ua qhov tseem ceeb ntawm qhov zoo -cov npe lag luam paub thaum lub sijhawm yuav khoom:
Cov Hom Tshuaj Hauv Tsev: ZZEC (Tshwj xeeb hauv zaj duab xis capacitors rau 18 xyoo, muab cov khoom siv vuam customized) - cov chaw tsim khoom ua yeeb yaj kiab capacitor;
Cov Hom Tshuaj Thoob Ntiaj Teb: Panasonic, Murata (Zoo heev - kev ua haujlwm zaus, tab sis tus nqi siab dua).
Tsis tas li ntawd, ib txwm tshuaj xyuas cov ntaub ntawv cov khoom lag luam kom paub meej cov kev qhia tshwj xeeb nrog cov khoom siv. Yog muaj lus nug, hu rau lub chaw tsim khoom pab neeg pab txhawb rau kev qhia.
Xaus
Kev xaiv cov yeeb yaj kiab capacitors ncaj qha cuam tshuam rau kev ua haujlwm, kev ua neej ntev, thiab kev nyab xeeb ntawm cov khoom siv vuam. Los ntawm kev sib piv cov ntsiab lus tseem ceeb, xaiv cov khoom siv hluav taws xob tsim nyog, ua tib zoo saib xyuas cov ntsiab lus zoo, thiab tso siab rau cov npe nrov, cov tuam txhab tuaj yeem txhim kho cov cuab yeej ua haujlwm tau zoo thiab txo cov nqi kho. Saib tom ntej, raws li kev siv tshuab vuam hloov mus rau cov kev daws teeb meem ntse, kev xaiv capacitor yuav ua rau muaj kev sib koom ua ke zoo nrog cov khoom siv. Cov neeg siv tau qhia kom nyob twj ywm paub txog kev lag luam thev naus laus zis nce qib.
