Lub luag hauj lwm ntawm Advanced Ceramics nyob rau hauv daim ntawv thov ntawm lub zog tshiab tsheb

Nrog rau txoj kev loj hlob sai ntawm lub zog tshiab tsheb kev lag luam, hluav taws xob transformation ntawm automakers tau dhau los ua tus qauv tseem ceeb. Cov khoom siv roj tsheb niaj hnub tau maj mam hloov los ntawm siab - cov khoom ua tau zoo yoog raws li lub zog tshiab. Advanced ceramics, vim lawv cov rwb thaiv tsev zoo heev, siab -kub tsis kam, hnav tsis kam, thiab siab- lub zog muaj zog, ua lub luag haujlwm tseem ceeb hauv lub zog tshiab lub tsheb thiab dhau los ua cov khoom siv tseem ceeb rau cov khoom tseem ceeb. Lawv cov ntawv thov muaj feem cuam tshuam nrog kev hloov kho thev naus laus zis ntawm metallized ceramic Cheebtsam.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Kev tswj hluav taws xob thev naus laus zis yog qhov taw qhia tseem ceeb rau kev ntsuas qib kev txhim kho ntawm lub zog tshiab. High-voltage DC ceramic relays, raws li cov ntsiab lus tseem ceeb ntawm kev tswj hluav taws xob, ua lub luag haujlwm tseem ceeb. Ib txwm relays raug txwv los ntawm kev tsim technology thiab tej zaum yuav ntsib teeb meem xws li kev sib cuag adhesion tsis ua hauj lwm los yog arc burnout thaum txuas high-voltage DC los yog qis- fais fab inductive loads. Txawm li cas los xij, lub siab tshiab -voltage DC lub tshuab nqus tsev relays zoo daws qhov teeb meem no.

 

Qhov no relay siv lub tshuab nqus tsev vacuum kaw los ntawm cov hlau thiab ceramic, tso siab rau cov txheej txheem Ceramic rau Hlau kom ua tiav kev sib xyaw ua ke ntawm cov khoom siv ceramic thiab hlau. Ceramic insulator yog slidably txuas ntawm qhov txav mus los ntawm cov khoom sib txuas thiab lub laub pas nrig, kom ntseeg tau tias cov kev txav mus los thiab zoo li qub tuaj yeem tuav cov hluav taws xob zoo hauv ob qho tib si kev coj ua thiab kev sib txuas, yog li ua kom lub zog tua hluav taws xob ntawm lub relay thaum hloov siab -voltage DC loads. Arcs yog lub ntsiab ua rau lub tsheb spontaneous combustion, thiab zoo heev rwb thaiv tsev cov khoom ntawm ceramics yog lub hauv paus kev txhawb nqa rau kev ua tiav "arc-dawb" kev twb kev txuas thiab disconnection. Cov qauv tseem ceeb ntawm lub plhaub ceramic yog ua los ntawm 95% alumina ceramic, uas yog ib qho tseem ceeb ntawm Metallized Ceramic Housing rau Fais Semiconductors.

Lub tshuab hluav taws xob tswj hluav taws xob yog qhov tseem ceeb ntawm cov tsheb tshiab lub zog. Lub IGBT (Insulated Gate Bipolar Transistor) module, raws li "central nervous system", yog lub hauv paus tseem ceeb ntawm lub zog tshiab tsheb thiab them pawg tsav tsheb, suav txog 40% txog 50% ntawm tus nqi tag nrho.

 

Thiab cov ceramic tooj liab- clad board yog cov khoom ntim tseem ceeb rau IGBT module. Ceramic tooj-clad board txais cov tooj liab-ceramic-tooj liab "sandwich" cov qauv sib xyaw, sib txuas cov rwb thaiv tsev siab, muaj zog txhua yam, zoo heev cua sov dissipation, thiab txuam thermal expansion yam ntxwv ntawm ceramics, raws li zoo raws li lub siab tam sim no - nqa muaj peev xwm, thermal conductivity {6} zoo heev thiab welding. tooj liab. Tam sim no, ceramic tooj liab- clad boards tau muab faib ua peb hom raws li cov ntaub ntawv ceramic: alumina, aluminium nitride, thiab silicon nitride.

 

Ntawm lawv, silicon nitride tooj liab- clad board muaj qhov ua tau zoo tshaj plaws, muaj lub zog siab thiab siab thermal conductivity. Ua ke nrog cov cuab yeej siv hlau ua haujlwm, nws txoj kev ntseeg tau zoo dua qub, ua rau nws cov khoom siv rau kev ntim khoom ntawm high-voltage thiab high-power IGBT modules, tshwj xeeb tshaj yog tsim nyog rau cov kev xav tau siab ntawm lub zog tshiab rau kev cia siab thiab miniaturization. Lub alumina ceramic tooj liab- clad board yog tsim los ntawm Alumina Metallized Ceramics thiab muaj cov txheej txheem rwb thaiv tsev thiab cov khoom cua sov.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Ceramic siab-voltage contactors tau dav siv hauv kev tswj fais fab, kev tiv thaiv hluav taws xob ntawm lub tsheb tshiab, nrog rau kev them cov pawg, roj teeb fais fab, hloov pauv zaus, capacitor ua ntej - them, thiab lwm yam kev tswj hluav taws xob. Cov txheej txheem tseem ceeb nyob hauv kev siv lub tshuab nqus tsev vacuum los txuas cov ceramic thiab carbide alloy los tsim cov kab noj hniav. Cov kab noj hniav sab hauv tau ntim nrog cov cua txias kom nrawm nrawm kom ua tiav qhov luv luv - lub sij hawm arc extinguishing.

 

Txij li thaum lub arc burning ua rau lub internal encapsulated gas kom nthuav vim cua sov, nws exerts nro ntawm lub vuam sib koom lub taub hau. Yog li ntawd, lub zog ntawm vuam sib txuas lub taub hau yog qhov tseem ceeb heev. Cov qauv encapsulation ntawm ceramics thiab Kovar alloy yog qhov tseem ceeb cuam tshuam rau kev sib koom ua ke. Tam sim no, ob daim ntawv encapsulation, uas yog lub tiaj sealing thiab ntsug sealing, tau dav siv. Cov tub ntxhais HVDC contactor ceramic enclosure cia siab rau cov yam ntxwv ntawm High-Strength Metallized Ceramic Cheebtsam los xyuas kom meej cov qauv lub zog thiab sealing kev ua tau zoo ntawm qhov chaw encapsulated.

Cov tsheb tshiab lub zog muaj kev ua tau zoo dua rau cov kabmob lub cev muaj zog dua li cov tsheb ib txwm muaj. Lub cev muaj zog bearings yuav tsum tau hloov mus rau siab -ceev, muaj zog sib nqus teb, thiab tsis tshua muaj hnav. Cov kev cai tshwj xeeb muaj xws li qhov qis qis, muaj zog hnav tsis kam, zoo rwb thaiv tsev kom txo tau hluav taws xob corrosion los ntawm kev coj tus kheej tawm, thiab smoother bearing pob nto kom txo tau hnav.

 

Ceramic npas, nrog lawv qhov tsawg ntom ntom, siab hardness, tsis kam mus rau kev sib txhuam, thiab cov khoom siv rwb thaiv tsev zoo heev, tau dhau los ua cov khoom siv zoo tshaj plaws rau kev ua haujlwm no. Lawv muaj lub luag haujlwm tsis tuaj yeem hloov pauv hauv siab - kub, muaj zog sib nqus, thiab siab - lub tshuab nqus tsev thiab tau dhau los ua cov ntawv thov sib txawv rau lub cev muaj zog hauv tsheb tshiab. Cov khoom tseem ceeb ntawm cov pob bearings ceramic yog ua tiav siv Precision Metallized Ceramics, ua tau raws li qhov siab -kev ua tau zoo ntawm cov tsheb tshiab lub zog. Lawv zoo heev hnav tsis kam thiab rwb thaiv tsev cov khoom zoo txhim khu kev ruaj ntseg thiab kev pab lub neej ntawm lub cev muaj zog.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Zuag qhia tag nrho, daim ntawv thov ntawm cov ceramics siab heev nyob rau hauv lub tshav pob ntawm lub zog tshiab tsheb feem ntau yog tsom rau cov tub ntxhais cov ntu xws li kev tswj hluav taws xob thiab kev tsav tsheb. Cia siab rau nws cov yam ntxwv ntawm cov khoom siv tshwj xeeb, nws tau daws qhov ua tsis tau zoo ntawm cov khoom siv hlau ib txwm muaj nyob rau hauv siab - siab, siab - kub, thiab muaj zog magnetic teb tej yam kev mob. Raws li lub zog tshiab tsheb hloov mus rau qhov siab voltage, lub teeb yuag, thiab kev ntseeg siab,ceramic metallizationthev naus laus zis txuas ntxiv ua kom zoo dua qub, thiab cov ceramics siab heev yuav nthuav dav lawv daim ntawv thov scenarios, txhawb kev txhim kho kev ua tau zoo ntawm cov khoom muaj feem cuam tshuam, thiab muab cov khoom tseem ceeb txhawb nqa rau siab - kev txhim kho zoo ntawm kev lag luam tsheb tshiab.
