Feem ntau cov high-voltage ceramic capacitors muaj ib tug disc-zoo li tus tsos, feem ntau nyob rau hauv xiav xim, txawm hais tias ib co manufacturers siv daj ceramic discs. Nyob rau hauv sib piv, cylindrical high-voltage ceramic capacitors, nrog lawv cov ntsia liaj qhov rooj terminals nyob rau hauv nruab nrab ntawm lub tsev, muaj epoxy sealing txheej uas sib txawv xim ntawm txawv manufacturers, xws li xiav, dub, dawb, xim av, los yog liab. Qhov sib txawv tseem ceeb ntawm ob hom yog raws li hauv qab no:
1) Hais txog kev tsim muaj peev xwm hauv kev ua lag luam, ceramic disc-hom high-voltage ceramic capacitors muaj peev xwm ntau dua. Lawv yog siv nyob rau hauv ntau yam kev siv, xws li electrostatic li, tsis zoo ions, high-voltage fais fab mov, voltage ob chav circuits, CT / X-ray tshuab, thiab lwm yam xwm txheej uas yuav tsum tau high-voltage Cheebtsam. Cylindrical high-voltage ceramic capacitors muaj peev xwm tsim tau qis dua thiab feem ntau yog siv rau hauv cov khoom siv hluav taws xob siab, siab tam sim no, tseem ceeb rau kev cuam tshuam ntawm cov mem tes, tso tawm, thiab lwm yam. Piv txwv li, lawv tau siv hauv cov khoom siv hluav taws xob zoo li cov ntsuas hluav taws xob siab thiab cov keyboards. , high-voltage pulse fais fab mov, high-power CT thiab MRI khoom, thiab ntau yam civil thiab kho mob lasers li them thiab tawm cov ntsiab lus.
2) Txawm hais tias cylindrical bolt davhlau ya nyob twg high-voltage ceramic capacitors tuaj yeem siv ntau yam ntaub ntawv ceramic xws li Y5T, Y5U, Y5P, cov khoom siv tseem ceeb yog N4700. Cov neeg siv khoom xaiv bolt terminals vim tias lawv ua ntej qhov kev ntsuas hluav taws xob ntau dua ntawm hom capacitor. Piv txwv li, qhov siab tshaj plaws ntawm cov hlau lead-hom capacitors yog nyob ib ncig ntawm 60-70 kV, thaum lub siab tshaj plaws voltage ntawm cylindrical ntsia liaj qhov rooj davhlau ya nyob twg capacitors muaj peev xwm tshaj 120 kV. Txawm li cas los xij, tsuas yog cov khoom siv N4700 tuaj yeem muab qhov siab tshaj plaws tiv thaiv qib siab nyob rau hauv tib cheeb tsam. Lwm hom ceramic, txawm tias lawv tsis tshua muaj peev xwm tsim cov capacitors, muaj lub neej luv luv thiab lub neej ntev ntawm lub capacitor tshaj N4700, uas tuaj yeem yooj yim ua rau muaj kev pheej hmoo zais. (Ceeb Toom: Lub neej ntev ntawm N4700 bolt capacitors yog 20 xyoo, nrog lub sijhawm lav ntawm 10 xyoo.)
Cov khoom siv N4700 kuj muaj qhov zoo xws li qhov kub me me coefficient, tsis tshua muaj kev ua haujlwm, cov yam ntxwv zoo zaus, tsis tshua muaj kev poob qis, thiab tsis tshua muaj kev cuam tshuam sab hauv. Qee qhov xiav-voltage ceramic nti capacitors kuj siv cov khoom siv N4700 thiab feem ntau siv hauv cov khoom siv hluav taws xob qis thiab qis tam sim no, xws li Philips / Siemens X-ray tshuab thiab CT scanners. Ib yam li ntawd, lawv lub neej kev pabcuam tuaj yeem ncav cuag 10 txog 20 xyoo.
3) Cov yam ntxwv siab zaus thiab siab tam sim no muaj peev xwm ntawm cylindrical high-voltage ceramic capacitors yog superior rau cov disc-type ceramic capacitors. Qhov ntau zaus ntawm cylindrical capacitors feem ntau yog nruab nrab ntawm 30 kHz thiab 150 kHz, thiab qee cov qauv tuaj yeem tiv taus tam sim no txog li 1000 A thiab txuas ntxiv ua haujlwm tam sim no ntawm ntau kaum ntawm Amperes lossis ntau dua. Ceramic disc capacitors, xws li cov khoom siv N4700, feem ntau yog siv nyob rau hauv high-frequency range ntawm 30 kHz mus rau 100 kHz, nrog rau tam sim no ratings feem ntau yog li ntawm kaum mus rau pua pua milliamperes.
4) Thaum xaiv cov high-voltage capacitors tsim nyog, engineers ntawm lub Hoobkas yuav tsum xav txog tsis tsuas yog tus nqi tab sis kuj cov ntsiab lus hauv qab no:
HVC cov neeg ua haujlwm muag khoom feem ntau nug txog cov neeg siv khoom siv, kev khiav hauj lwm zaus, qhov kub thiab txias, ib puag ncig ntawm qhov chaw, mem tes voltage, overcurrent, thiab seb puas muaj qhov yuav tsum tau muaj rau cov nqi tso tawm ib nrab. Qee cov neeg siv khoom kuj xav tau kev tiv thaiv qis, me me, lossis lwm yam tshwj xeeb. Tsuas yog los ntawm kev nkag siab cov ntsiab lus tshwj xeeb no tuaj yeem HVC cov neeg muag khoom tau pom zoo sai thiab muab cov khoom siv hluav taws xob tsim nyog.
