Aug 06, 2026
Lub metallized ceramic Cheebtsam rau lub zog tshiab HVDC contactors siv 95% – 99% alumina ceramic li cov insulating substrate, ua tau ib tug txhim khu kev qha kev twb kev txuas ntawm cov ceramic thiab hlau terminals los ntawm Mo-Mn metallization, siab-kub sintering, thiab brazing txheej txheem. Cov khoom no muaj lub zog dielectric ntau tshaj 15 kV / mm, rwb thaiv tsev tiv thaiv ntau dua 1000 MΩ, thiab txhua yam muaj zog ntawm 200 txog 500 MPa; Nws yog feem ntau siv hauv HVDC contactors rau lub zog tshiab tsheb, lub zog cia tshuab, photovoltaic inverters, thiab siab -voltage fais fab khoom, kom ntseeg tau hluav taws xob cais thiab ruaj khov Circuit Court cuam tshuam nyob rau hauv siab -voltage, high{11}} ib puag ncig tam sim no.
Vim li cas HVDC contactors siv metallized ceramic lub cev rau siab -voltage rwb thaiv tsev?
Lub tshuab hluav taws xob roj teeb rau cov tsheb tshiab lub zog tau hloov pauv ntawm 400V mus rau 800V siab- lub tshuab hluav taws xob, thaum lub zog hluav taws xob hauv lub zog khaws cia thiab DC sab ntawm cov tshuab hluav taws xob photovoltaic kuj tseem nce ntxiv. HVDC contactors yuav tsum muaj kev ruaj ntseg rwb thaiv tsev nyob rau hauv tej yam kev mob ntawm high voltage, siab tam sim no, thiab nquag hloov, nyob rau tib lub sij hawm withstanding mechanical shock los ntawm kev sib cuag actuation thiab thermal shock los ntawm hluav taws xob arcs.
Raws li qhov tseem ceeb ntawm cov txheej txheem insulating ntawm HVDC contactors, metallized ceramic lub cev muaj feem ntau ntawm ceramic substrate thiab localized metallized txheej. Cov seem ceramic muab kev ua haujlwm siab rwb thaiv tsev thiab kev txhawb nqa txhua yam, thaum lub metallized cheeb tsam pab txhawb kev sib txuas ntawm tooj liab terminals, electrodes, lossis kev sib cuag sib txuas, yog li ua kom muaj kev sib txuas hluav taws xob zoo rau cov khoom siv ceramic.
Hauv kev tsim qauv tsim, cov khoom siv ceramic feem ntau tau teeb tsa raws li cov blocks, lub tog raj kheej, lossis cov duab nyuaj, kho kom haum rau tus contactor lub sab hauv arc -extinguishing chamber, terminal layout, thiab mounting method. Qee cov qauv tsim suav nrog qhov chaw qhov chaw, qhov grooves, thiab cov khoom siv ntxiv los txhim kho kev sib dhos precision thiab kev ntseeg tau ntawm txhua yam.
Lawv lub luag haujlwm tseem ceeb suav nrog:
- Muab cov rwb thaiv tsev ruaj khov thiab kev sib cais ntawm kev txav mus los thiab nyob ruaj khov tiv thaiv kom tsis txhob muaj hluav taws xob siab - tawg.
- Muab kev txhawb nqa tshuab rau kev sib txuas lus sab hauv kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov.
- Ua kom muaj kev sib txuas txhim khu kev qha ntawm cov khoom siv ceramic thiab hlau- xws li tooj liab lossis stainless hlau - ntawm cov txheej metallized.
- Ua kom muaj kev ruaj ntseg nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias, hluav taws xob arcs, thiab kev co.
95% Alumina Ceramic Cov Khoom Siv Ua Tau Raws Li Siab -Voltage Insulation Requirements for New Energy Applications
Cov khoom siv ceramic ntawm HVDC contactors xav tau cov khoom siv siab, xav tau qhov sib npaug ntawm rwb thaiv tsev, hluav taws xob, khoom siv, thiab thermal stability. Tam sim no, 95% alumina (95% Al₂O₃) yog cov khoom siv dav tshaj plaws hauv lub tsheb tshiab thiab lub zog cia khoom.
Alumina ceramics muaj lub zog dielectric siab, siab txhua yam muaj zog, thiab ua haujlwm kub zoo heev. Ua kom cov ntsiab lus alumina ntxiv ntxiv txhim kho cov khoom siv qhov ntom ntom, kev ua haujlwm rwb thaiv tsev, thiab tiv thaiv kev puas tsuaj.
Silicon nitride (Si₃N₄) ceramics kuj tseem siv rau hauv qee qhov kev ua haujlwm siab -kev ua haujlwm vim lawv cov thermal shock tsis kam thiab hnav tsis kam; Txawm li cas los xij, lawv txoj kev saws me nyuam hauv HVDC contactors tseem muaj qhov txwv vim yog cov nqi tsim khoom ntau dua thiab cov kev cai nruj rau kev sib xyaw ua ke ntawm metallization.
| Performance Parameter | 95% Alumina Ceramic | Silicon Nitride Ceramic | Engineering Application Sib txawv |
|---|---|---|---|
| Lub ntsiab lus | Al₂O₃ Ntau dua lossis sib npaug li 95% | Si₃N₄ | Alumina yog dav siv rau HVDC rwb thaiv tsev Cheebtsam; silicon nitride raug xaiv rau siab -kub thiab siab - ib puag ncig cuam tshuam |
| Dielectric zog | >15 kV / hli | 15-20kV / hli | Ob leeg muab kev ua haujlwm siab rwb thaiv tsev, thaum alumina muab cov nqi zoo dua -kev ua tau zoo rau HVDC contactor daim ntawv thov |
| Flexural zog | 300-500MPa | 600-900MPa | Silicon nitride muab ntau dua txhua yam lub zog, thaum alumina ua tau raws li feem ntau cov hluav taws xob rwb thaiv tsev |
| Thermal Expansion Coefficient | 6-8×10⁻⁶/K | 3-4×10⁻⁶/K | Alumina muaj qhov zoo sib xws nrog cov khoom siv hlau sib xws xws li tooj liab thiab npib tsib xee alloys |
| Tej kev siv | HVDC contactors, high voltage fuse raj, ceramic rwb thaiv tsev lub cev | Siab -cov khoom kub, cuam tshuam-cov khoom siv ceramic | Cov khoom xaiv nyob ntawm qib voltage, thermal load thiab mechanical xav tau |
Rau siab -voltage systems nyob rau hauv lub zog tshiab tsheb, ceramic lub cev feem ntau yuav tsum tau raws li nram no engineering specifications:
| qhov project | Yam tsis muaj |
| Rwb thaiv tsev tsis kam | >1000 MΩ; some products >10,000 MΩ |
| Kev khiav hauj lwm nrog voltage | 1000V-3000V DC |
| Flexural zog | 200-500MPa |
| Compressive zog | >1000MPa |
Cov kev ntsuas no xyuas kom meej tias lub cev ceramic tswj kev ua haujlwm ruaj khov nyob rau hauv cov xwm txheej ntawm qhov hloov pauv ntawm qhov hluav taws xob, qhov kub thiab txias, thiab kev co txhua yam.
Txheej txheem tswj rau Mo-Mn Metallization thiab Ceramic-rau- Hlau Brazing
Cov ntaub ntawv ceramic tsis tuaj yeem tsim cov ntawv cog lus ncaj qha nrog cov hlau xws li tooj liab, npib tsib xee, lossis hlau; Yog li ntawd, cov txheej txheem metallization yuav tsum tau tsim kom muaj cov txheej txheem kev sib txuas ntawm cov khoom siv ceramic.
Cov txheej txheem Mo-Mn metallization feem ntau yog siv rau lub cev ceramic ntawm HVDC contactors. Cov txheej txheem no suav nrog kev luam ntawv molybdenum-manganese (Mo-Mn) muab tshuaj txhuam rau hauv alumina ceramic nto thiab tua nws ntawm qhov kub thiab txias los ua cov txheej metallized, ua raws li cov npib tsib xee plating txhawm rau txhim kho kev ua haujlwm brazing tom ntej.
