Cov Lus Qhia Tshwj Xeeb

Cov yam ntxwv kev ua tau zoo ntawm cov zaj duab xis capacitors sib txawv feem ntau nyob ntawm cov khoom siv dielectric siv nrog rau cov thev naus laus zis siv. Qee cov yas zaj duab xis dielectrics feem ntau siv suav nrog polyethylene naphthalate (PEN), polyethylene terephthalate (PET), thiab polypropylene (PP).

Cov yas zaj duab xis capacitors muaj peev xwm muab faib ua zaj duab xis/ntawv ci thiab cov hlau zaj duab xis capacitors. Lub hauv paus ntawm cov zaj duab xis/ntawv ci capacitor muaj ob lub hlau ntawv ci electrodes thiab ib lub yas zaj duab xis dielectric ntawm lawv. Zaj duab xis/ntawv ci capacitors muaj kev tiv thaiv rwb thaiv tsev siab, muaj peev xwm tswj tau lub zog siab, muaj peev xwm nqa tam sim no zoo heev, thiab muaj peev xwm ruaj khov zoo. Tsis zoo li zaj duab xis/ntawv ci capacitors, cov hlau zaj duab xis capacitors siv cov hlau-coated yas zaj duab xis ua electrodes. Metallized zaj duab xis capacitors muaj qhov loj me me, thiab muaj kev ua haujlwm siab volumetric, muaj peev xwm ruaj khov zoo, tsis tshua muaj dielectric poob, thiab zoo heev kho tus kheej. Qee cov capacitors yog cov sib xyaw ntawm zaj duab xis/ntawv ci capacitors thiab metallized zaj duab xis capacitors thiab cov yam ntxwv ntawm ob hom. Cov khoom kho tus kheej ntawm cov hlau zaj duab xis capacitors ua rau lawv zoo tagnrho rau ntau yam kev siv, suav nrog lub neej ntev thiab cov voj voog tsis ua haujlwm zoo.

Kev kho tus kheej ntawm cov capacitors metallized film

Cov yas zaj duab xis dielectrics uas feem ntau siv rau hauv kev tsim cov metallized film capacitors suav nrog polypropylene (PP), polyphenylene sulfide (PPS), polyester, thiab metalized paper (MP). Cov ntaub ntawv dielectric no muaj peev xwm kho tus kheej sib txawv.

Thaum lub capacitor zaj duab xis metallized tawg, arcing ua rau cov hlau nyias nyias nyob ib puag ncig thaj chaw ua txhaum kom vaporize. Cov txheej txheem vaporization no tshem tawm cov hlau conductive hauv thaj chaw nyob ib puag ncig qhov tsis zoo. Txij li thaum cov khoom siv conductive raug tshem tawm, lub voj voog luv luv yuav tsis tshwm sim ntawm cov phaj. Qhov no tiv thaiv kev ua tsis tiav ntawm cov khoom.

Lub peev xwm kho tus kheej ntawm lub capacitor zaj duab xis metallized nyob ntawm ntau yam xws li cov khoom ntawm cov khoom siv dielectric thiab qhov tuab ntawm cov hlau txheej. Cov txheej txheem vaporization xav tau cov pa oxygen txaus thiab cov ntaub ntawv dielectric nrog cov pa oxygen siab muaj cov khoom kho tus kheej zoo. Qee cov yas zaj duab xis dielectrics uas muaj cov yam ntxwv kho tus kheej zoo suav nrog polypropylene, polyester thiab polycarbonate. Ntawm qhov tod tes, yas zaj duab xis dielectrics nrog cov pa oxygen qis muaj cov yam ntxwv kho tus kheej tsis zoo. Polyphenylene sulfide (PPS) yog ib qho khoom siv dielectric zoo li no.

Sib nrug ntawm kev txhim kho kev ntseeg siab, lub peev xwm kho tus kheej ntawm cov metallized zaj duab xis capacitors pab txhim kho lawv lub neej ua haujlwm. Txawm li cas los xij, kev kho tus kheej ua rau txo qis ntawm thaj chaw metallized electrode dhau sijhawm.

Hauv cov ntawv thov, qee qhov xwm txheej uas tuaj yeem ua rau qhov ua tsis tiav ntawm ib qho khoom suav nrog qhov kub siab, qhov hluav taws xob siab, xob laim, av noo siab, thiab kev cuam tshuam hluav taws xob (EMI).

Sib nrug ntawm cov khoom zoo kho tus kheej, cov metallized polyester zaj duab xis capacitors kuj muaj qhov siab dielectric tas mus li, qhov kub zoo ruaj khov, dielectric zog siab, thiab volumetric efficiency zoo heev. Cov yam ntxwv no ua rau cov capacitors no zoo tagnrho rau cov ntawv thov dav dav. Metallized polyester capacitors yog dav siv rau DC daim ntawv thov xws li thaiv, bypassing, decoupling, thiab suab nrov suppression.

Cov capacitors polypropylene metallized muaj kev tiv thaiv rwb thaiv tsev siab, kev nqus dielectric tsawg, kev poob dielectric tsawg, lub zog dielectric siab, thiab kev ruaj khov mus sij hawm ntev. Cov khoom siv txuag chaw no siv dav hauv cov ntawv thov txuas nrog lub ntsiab xws li cov voj voog lim dej, cov teeb pom kev zoo ballasts, thiab cov voj voog snubber. Ob chav metallized polypropylene zaj duab xis capacitors tuaj yeem tiv taus qhov hluav taws xob siab thiab cov khoom siv siab, thiab lawv tsim nyog rau cov ntawv thov uas muaj feem yuav muaj cov pulses siab. Cov capacitors no feem ntau siv rau hauv cov tswj lub cev muaj zog, snubbers, cov khoom siv fais fab hloov hom, thiab cov saib xyuas.

Qhov kev ntseeg tau thiab lub neej ua haujlwm ntawm cov capacitors nyob ntawm seb lawv tus kheej kho tau zoo li cas. Cov khoom passive nrog cov yam ntxwv zoo kho tau zoo dua thiab muaj lub neej ua haujlwm ntev dua. Cov yam ntxwv zoo kho tau zoo ntawm cov metallized film capacitors ua rau lawv muaj zog thiab ua rau lawv haum rau ntau daim ntawv thov. Tsis tas li ntawd, cov khoom ruaj khov no tsis ua haujlwm qhib-circuit, thiab qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau cov khoom nrog hom kev ua haujlwm tsis zoo.

Ntawm qhov tod tes, cov khoom siv kho tus kheej ntawm cov metallized film capacitors ua rau qhov poob qis nce thiab tag nrho cov capacitance poob qis. Sib nrug los ntawm cov khoom siv kho tus kheej zoo, feem ntau cov metallized film capacitors kuj muaj lub zog tawg siab thiab kev ua haujlwm volumetric siab.
