Al2O3 Alumina Ceramic Housing rau High Voltage DC Contactors tsim cov thawj insulating barrier nyob rau hauv high-voltage DC contactors rau hluav taws xob tsheb powertrain thiab tauj dua-lub zog cia systems. Cov khoom siv alumina yuav tsum tiv taus DC voltage, arc thermal shock, thiab cyclic mechanical vibration yam tsis muaj dielectric tawg. Cov khoom seem stability ncaj qha txiav txim siab tag nrho cov kev pab cuam lub neej ntawm high-voltage DC switching assemblies.
Ua hauj lwm-Txheej xwm Loads ntawm High -Tub kub Metallized Ceramic Relay Case
High-voltage DC contactors ua rov ua dua thiab ua haujlwm rau cov hluav taws xob ncaj qha tam sim no hla EV roj teeb pob, cov khoom siv hluav taws xob photovoltaic thiab cov khoom siv hluav taws xob cua. Internal hluav taws xob arcs generated thaum lub sij hawm sib cais tso tawm instantaneous high-kub kub flux uas muaj peev xwm ncav cuag ntau txhiab degrees Celsius. Raws li cov ntaub ntawv polymer-raws li cov ntaub ntawv raug kev txom nyem carbonization, thermal deformation thiab rwb thaiv tsev tsis ua hauj lwm nyob rau hauv lub sij hawm ntev arc hluav taws xob.
EV Alumina Ceramic Housing dais feem ntau ntawm hnyav thermal thiab hluav taws xob loads nyob rau hauv lub kaw arc-extinguishing chamber. Lub tsheb tsis tu ncua kev co, nquag hloov hluav taws xob thiab qhov dav ntawm qhov ntsuas kub hloov pauv ntawm −40℃mus rau +125℃ntxiv cov kev ntxhov siab ntxiv rau cov qauv vaj tsev. Txhua qhov tawg, qhov sib txawv ntawm huab cua lossis qhov chaw tsis zoo ntawm cov khoom siv ceramic yuav txo qis dielectric tsis kam thiab ua rau muaj kev pheej hmoo ntawm kev sib tsoo luv luv. Cov ntaub ntawv tsis ua hauj lwm hauv teb qhia tau hais tias kev puas tsuaj ntawm cov vaj tsev nyob rau feem ntau ntawm tag nrho cov high-voltage DC contactor breakdown kis nyob rau hauv lub ntiaj teb no kev khiav hauj lwm mus.
Vim li cas 95% -96% Alumina Metallized Ceramics Outperforms Yas thiab Epoxy Insulators
Kev xaiv cov khoom siv rwb thaiv tsev ncaj qha teeb tsa qhov kev ua haujlwm siab tshaj ntawm high-voltage DC contactor hardware. Hloov kho engineering yas muaj cov khoom siv raw khoom qis, tab sis nws cov thermal conductivity nyob qis dua 0.3 W / (m·K), thiab deformation mus tas li yuav tshwm sim nyob rau hauv cov cua sov hauv zos. Epoxy potting cov kev daws teeb meem txhim kho ib feem ntawm kev tawm tsam, tab sis tsis tuaj yeem tiv taus rov qab thermal cycling qaug zog nyob rau hauv lub tsheb ib puag ncig.
95 mus rau 96 feem pua alumina ceramic muab lub zog dielectric siab tshaj 15 kV / mm thiab thermal conductivity ntawm 18-22 W / (m·K). Cov khoom no tiv thaiv arc ablation thiab tswj cov khoom tiv thaiv ruaj khov tom qab ntau txhiab ntawm kev tawm mus. EV Alumina Ceramic Relay Housing ua kom ruaj khov geometric qhov ntev nyob rau hauv qhov kub thiab txias, uas yuav pab tswj kom muaj kev sib haum xeeb hauv nruab nrab ntawm kev txav mus los thiab kev sib cuag ruaj khov hauv lub arc chamber. Qhov qis thermal expansion coefficient kuj txo cov kev ntxhov siab ntawm kev sib dhos ntawm lub plhaub ceramic thiab cov hlau nyob ib puag ncig.
Dimensional and Surface Quality Specifications for Alumina Ceramic Housing
Precision machining thiab kev kho saum npoo yog cov kauj ruam tseem ceeb rau kev ua tiav Relay Alumina Ceramic Cheebtsam. Machining kam rau ua rau mounting qhov thiab sealing mating nto ib txwm xav tau ± 0.05 hli los yog nruj dua. Qhov sib txawv ntawm qhov sib txawv uas tsis muaj kev tswj hwm yuav ua rau kev sib dhos tsis zoo, tsim kev sib khi tsis sib xws, thiab rhuav tshem cov huab cua nruj ntawm qhov arc-extinguishing kab noj hniav.
Nto tiav ncaj qha cuam tshuam kev ua haujlwm ib nrab-tso tawm. Pom pom khawb, micro-qhov thiab seem burrs ntawm cov phab ntsa ceramic sab hauv mloog cov hluav taws xob hauv zos, thiab ua rau cov rwb thaiv tsev tawg ntawm kev ua haujlwm ntsuas hluav taws xob. Cov neeg tsim khoom nqa tawm kev sib tsoo, polishing thiab ntug chamfering rau txhua qhov DC Relay Metallized Welded Ceramic Housing. Tom qab-sintering dimensional soj ntsuam, high-voltage withstand test thiab thermal shock cycling test yog siv los tshuaj xyuas cov khoom puas ua ntej xa khoom.
Kev lag luam xav tau rau high-voltage DC contactors tseem loj hlob raws li EV thiab daim phiaj-txheej txuas ntxiv-zog cov phiaj xwm nthuav dav. OEM engineers tam sim no tso cov kev cai nruj dua ntawm cov khoom siv rwb thaiv tsev nyob ruaj khov thiab ib feem sib xws. Cov khoom lag luam yuav tsum sib npaug ntawm cov khoom siv raw, sintering nkhaus, thiab cov txheej txheem machining kom tsim nyog los tsim cov khoom tsim nyog Metallized Welded Ceramic Housing rau cov khoom siv ntau lawm.
