Srew davhlau ya nyob twg hom high voltage ceramic capacitor kuj hu ua "Doorknob Capacitor"in English los yog  High Voltage Ntsia Hlau Terminal Ceramic Capacitor. Lub tuam txhab Japanese nto moo TDK (Tokyo Denkikagaku Kogyo) hais txog nws li "Ultra High Voltage Ceramic capacitor." Txij li thaum Japanese electronics loj heev Murata tshaj tawm kev txiav tawm ntawm high voltage ntsia hlau davhlau ya nyob twg capacitors nyob rau hauv lub caij nplooj zeeg 2018, lub siab tshaj plaws kev lag luam qhia nyob rau hauv Tuam Tshoj yog tuav los ntawm Japanese hom TDK. TDK muaj ntau tshaj li 40 xyoo ntawm kev tsim thiab kev lag luam ntawm ultra-high voltage ceramic capacitors, uas yog dav siv nyob rau hauv Suav teb fais fab transformers, Circuit Court breakers, high-end kho mob CT tshuab, muaj NDT tsis-kev soj ntsuam, high-power laser riam phom, high-voltage electrostatic precipitators, thiab lwm yam. TDK kev muag khoom tsom feem ntau yog nyob rau hauv Nyiv, Kaus Lim Qab Teb, Russia, thiab thaj av Asia-Pacific, nrog tsawg dua nyob rau hauv European thiab Asmeskas kev lag luam.

 

Txij li thaum lub sijhawm qub Thawj Tswj Hwm Trump, cov kev txwv tau raug txwv rau Suav tuam txhab uas muag txog cov khoom siv thev naus laus zis xws li cov chips high-end thiab cov khoom siv hluav taws xob. Ntau lub tuam txhab teev npe, cov tuam txhab lag luam hauv xeev, thiab cov khoom lag luam loj hauv Suav teb tau pib xav txog lwm txoj hauv kev rau cov khoom tseem ceeb. Lwm txoj hauv kev thiab hloov ntawm TDK's ultra-high voltage ceramic capacitors kuj tau muab tso rau hauv cov txheej txheem.

 

Nyob rau hauv qhov tseeb, ib co zoo heev Suav high-voltage ceramic capacitor chaw tsim tshuaj paus xws li HVC Capacitor tau ntse hloov high voltage ntsia hlau davhlau ya nyob twg ceramic capacitors los ntawm paub zoo Japanese hom MURATA thiab American hom Vishay. HVC capacitors tau txais kev lees paub ntev ntev los ntawm ntau lub tuam txhab European thiab Asmeskas cov npe thiab Fortune 500 tuam txhab. Vim cov khoom siv thiab cov khoom muaj kev txwv, TDK cov khoom tsis muab tib theem ntawm kev paub rau European thiab Asmeskas cov neeg siv khoom xws li MURATA los ntawm Nyiv thiab Vishay los ntawm Tebchaws Meskas. Tsis ntev los no, muaj kev tawm tswv yim los ntawm European thiab Suav cov koom haum tshawb fawb thiab cov neeg siv khoom kawg qhia tias TDK cov khoom lag luam tsis zoo thiab qee qhov tsis zoo piv rau HVC capacitors. Yog li ntawd, cov neeg siv khoom tau xaiv los siv HVC capacitors es tsis txhob Japanese TDK cov khoom. 

1) Siv tau Voltage thiab Capacitance Range: TDK ultra-high voltage ceramic capacitors: 20KV-50KV (Z5T, Y5P, Y5S cov ntaub ntawv); HVC doorknob hom high-voltage ceramic capacitors: 10KV txog 150KV (cov ntaub ntawv tseem ceeb yog N4700, Y5U, Y5T, thiab lwm yam). Lub siab tshaj plaws voltage capacitance qauv tam sim no muab los ntawm TDK yog FHV-12AN 50KV 2100PF, Y5S khoom. HVC muab cov khoom txheem rau cov neeg siv khoom xws li 50KV 8000PF N4700, 60KV 2000PF N4700, 150KV 1000PF N4700, thiab lwm yam. Thaum cov neeg muas zaub xav tau ib tug ua hauj lwm voltage siab tshaj 50KV, HVC capacitors muaj peev xwm muab ib tug nplua nuj ntau yam ntawm high voltages thiab txawm loj heev capacitances.



2) Cov txheej txheem zoo npaum li cas ntawm TDK's Z5T, Y5P, Y5S dielectric khoom capacitors?

HVC's engineers tau ntsuas TDK's 30KV 2700PF thiab 50KV 2100PF ntsia hlau capacitors thiab pom tias txawm tias TDK siv Class 2 ceramics Y5S, Z5T, thiab cov khoom siv lead ua (claimed raws li ROHS qhov kev zam zam ntawm lawv lub vev xaib), DF (dissipation factor) Qhov tseem ceeb mus txog qib 1 ceramic N4700. Qhov no surpasses cov khoom ntawm Suav counterparts nyob rau hauv no nam.
 

 

3) Internal qauv ntawm lub capacitor: TDK's ultra-high voltage ceramic capacitors siv cov qauv ib txwm siv los ntawm ceramic nti, thiab epoxy resin encapsulation pwm muaj tus qauv loj ntawm tsuas yog 60 hli, raws li tau hais los saum no, uas txwv cov qauv tsim kom siab tshaj plaws ntawm 50KV 2100PF Y5S capacitor. HVC ntiav cov qauv tsim kho tshiab nrog dual-chip series lossis kev sib txuas ua ke, ua kom cov khoom siv capacitor specifications deb tshaj cov tuam txhab paub zoo. Capacitors nrog high voltages xws li 80KV, 100KV, thiab 150KV yog muab los ntawm dual-chip series kev twb kev txuas, thaum capacitance qhov tseem ceeb ntawm Class 1 ceramic 5000PF thiab txawm 8000PF yog tiav los ntawm dual-chip parallel kev sib txuas.


4)Disc txheej thiab lwm yam nthuav dav: TDK ceramic nti nto ib txwm txheej txheej capacitance los ntawm "silver plating." Silver ions yog cov conductors zoo heev, tab sis kuj muaj kev tsiv teb tsaws chaw. Nyob rau hauv sib piv, HVC ntsia hlau capacitors nyob rau hauv lub tsho tiv no ceramic nti nrog tooj liab electrodes, muab zoo kuj rau high voltage thiab siab tam sim no muaj peev xwm piv rau cov pa nyiaj plating. (Lub duab saum toj no qhia TDK capacitors yam tsis muaj epoxy resin txheej, tshem tawm los nthuav qhia ceramic chips nrog nyiaj plating thiab hlau terminals, thiab duab hauv qab no tso saib qhov tshwj xeeb tooj liab plating tshuab rau saum npoo ntawm HVC capacitors.)






Hauv kev xaus, TDK thiab HVC's ntsia hlau davhlau ya nyob twg hom ceramic capacitors txhua tus muaj lawv tus kheej zoo tshaj plaws, ua rau lawv sib npaug sib npaug sib tw. Hauv qee qhov, HVC txawm ua tau zoo tshaj lub tuam txhab Japanese TDK. Txawm li cas los xij, xav txog yam xws li kev xa khoom xa tuaj rau lub sijhawm thiab tus nqi uas cov neeg yuav khoom ib txwm xav txog, qhov zoo nkauj ntawm TDK's ultra-high voltage ceramic capacitors ib txwm poob luv luv piv rau HVC.

Lub ntiaj teb no tus naj npawb ib hom rau high-voltage ntsia hlau hom ceramic capacitors yog Japanese Murata. Hauv 2018, tom qab Murata tshaj tawm nws qhov kev txiav tawm, lub tuam txhab Asmeskas VISHAY thiab Nyij Pooj tuam txhab TDK feem nrhiav kom ua tiav lub tshuab nqus tsev sab laug los ntawm Murata los ntawm kev tshaj tawm xov xwm thiab sau cov ntaub ntawv "cross-reference" cov ntaub ntawv ntawm TDK cov vev xaib raug cai.



Thaum muab piv rau Japanese TDK thiab American Vishay, HVC Capacitor tseem yog ib qho kev xaiv zoo dua rau Murata.

1) Nws tuaj yeem pom tias TDK qhov hloov pauv rau Murata tsuas yog hloov pauv tsis zoo. Piv txwv li, Murata's DHS4E4C532KT2B 15KV 5300PF N4700 yog sib npaug los ntawm TDK nrog rau kev hloov pauv ntawm 15KV 7000PF, Y5S. Peb paub tias txawm hais tias TDK's Y5S cov ntaub ntawv pov thawj qhov kev ua haujlwm qis qis, qhov ntsuas qhov tseeb qhia qhov muaj txiaj ntsig zoo ib yam li qib N4700. Txawm li cas los xij, Chav Kawm 2 ceramics zoo li Y5S tsis tuaj yeem ua tau zoo li Class 1 ceramics nyob rau hauv qhov chaw siab. Tsis tas li ntawd, lub peev xwm 7000PF los ntawm TDK tej zaum yuav loj dhau rau cov neeg siv khoom siv Murata capacitors, thiab qhov sib xyaw qhov ntev yuav tsis ua raws li cov khoom qub Murata. Xav tias TDK tseem yog cov chaw tsim khoom loj thoob ntiaj teb, tshwj tsis yog cov neeg siv khoom muaj zog heev, TDK yuav tsis kam rov tsim pwm thiab siv tib theem ntawm cov khoom siv ceramic rau Murata hloov.



Yog tias HVC tau muab kev hloov pauv rau tus qauv Murata no, thawj zaug HVC tus qauv doorknob capacitor cov khoom lag luam npe yog cov khoom lag luam zoo tshaj plaws hauv kev ua lag luam rau cov khoom siv hluav taws xob high-voltage ntsia hlau davhlau ya nyob twg, suav nrog tag nrho cov qauv catalog los ntawm cov khoom lag luam sab saum toj thiab qib thib ob hauv tsev thiab thoob ntiaj teb, xws li Murata, TDK, Vishay, HVCA, thiab lwm yam. Qhov tseem ceeb, txhua tus qauv Murata uas tau tshaj tawm rau pej xeem hauv Is Taws Nem muaj cov tshuaj npaj tau los ntawm HVC. Txawm hais tias Murata capacitors nrog customized qhov ntev thiab cov hlau terminals rau qee cov neeg siv khoom loj uas yuav tsis pom hauv online (piv txwv li, 40KV 3000PF N4700 capacitor los ntawm lub tuam txhab hluav taws xob hauv Nyiv Sumitomo Electric), HVC yuav muab 1: 1 kev cai daws teeb meem ntawm heev. tus nqi pwm qis. Tsis tas li ntawd, qhov muaj peev xwm, kev ua siab ntev, cov khoom siv, thiab lwm yam, yog qhov tseem ceeb zoo ib yam rau thawj Murata specifications, thiab qee zaum, HVC txawm siv Class 1 "N4700" ceramics khoom los hloov Murata Class 2 "Z5U" ceramics khoom, zoo ib yam li Suav keeb kwm yav dhau los ntawm "Kev Sib Tw ntawm Swift Nees."

2) Tsis tas li ntawd, txawm hais tias TDK yog lub ntiaj teb nto moo Japanese cov khoom siv hluav taws xob, kev sib txuas lus thiab kev pabcuam ntawm TDK cov ceg thiab cov neeg sawv cev sab nraud ntawm Nyij Pooj tsis muaj zog li cov neeg ua haujlwm ntawm HVC. Muaj qee qhov xwm txheej uas tus neeg siv khoom los ntawm lub tuam txhab hluav taws xob German tau tshaj tawm tias thaum kuaj nrog ob qho tib si TDK thiab HVC capacitors, TDK tus neeg sawv cev tsis tau muab kev txhawb nqa txaus. Hauv qhov sib piv, HVC tus neeg sawv cev German, AMEC, tau mus xyuas cov neeg siv khoom tseem ceeb, ua kom cov neeg siv khoom txaus siab los ntawm kev sib txuas lus zoo, thiab ua kom pom kev hloov pauv hauv kev ua haujlwm, ua rau muaj kev xav zoo rau cov neeg siv khoom. Hauv kev lag luam xws li cov cuab yeej tseem ceeb xws li fais fab transformers, kev txhawb nqa muaj txiaj ntsig zoo los ntawm cov neeg siv khoom kawg.

3) Tom qab ntau xyoo ntawm kev siv zog, HVC Capacitor tau txais kev lees paub thiab ua tiav cov khoom xa tuaj los ntawm cov neeg siv khoom siab-voltage screw capacitor xws li Nikon, Konica Minolta, GE Healthcare, Johnson & Johnson, Baker Hughes, thiab lwm yam. Kev ua lag luam nrog cov neeg siv khoom Nyij Pooj thiab Fortune 500 cov tuam txhab qhia tias HVC Capacitor ua tau raws li cov kev cai nruj ntawm cov neeg siv khoom xav tau tshaj plaws hauv kev lag luam.




Hauv cov ntsiab lus, HVC Capacitor yog qhov tsim nyog hloov pauv rau lub siab-voltage ntsia hlau capacitors los ntawm Japanese hom Murata piv rau TDK. Rau qee qhov, HVC cov khoom tuaj yeem muab cov neeg siv khoom uas twb muaj lawm ntawm TDK ultra-high voltage capacitors ib qho kev sib txawv ntawm kev siv tshuab.

Hauv qab no yog cov qauv kev sib piv ntawm tag nrho cov ntau yam ntawm high-voltage ntsia hlau capacitors los ntawm TDK thiab HVC:
