Nyob rau hauv siab -voltage systems xws li hluav taws xob tsheb roj teeb pob, lub zog cia converters, thiab DC ceev them chaw nres tsheb, siab -voltage DC relays ua lub luag haujlwm tseem ceeb hauv kev sib txuas thiab txiav tawm DC circuits ntawm ntau pua lossis ntau txhiab volts. Txhawm rau kom ntseeg tau tias lub arc tsim thaum cov neeg sib cuag raug tua tau zoo thiab ua kom lub rwb thaiv tsev tiv thaiv qhov hluav taws xob ntawm cov neeg sib cuag nyob rau lub sijhawm ntev, cov relays feem ntau siv cov qauv kaw cov kab noj hniav uas muaj qhov siab - siab hydrogen lossis nitrogen sib tov. Lub airtightness ntawm High Temperature Metallized Ceramic Relay Case yeej tseem ceeb txiav txim siab ntev -lub sij hawm ruaj khov ntawm relay lub rwb thaiv tsev kev ua tau zoo. Thaum ib qho xau me ntsis tshwm sim hauv cov kab noj hniav, qhov chaw nyob ib puag ncig nruj nreem kaw yuav maj mam deteriorate, ua rau muaj kev hem thawj rau cov khoom siv thiab kev nyab xeeb.
Alumina Relay Ceramic Envelope rau Lub Tsheb Hluav Taws Xob feem ntau yog tsim los ntawm metallizing thiab vuam lub nplhaib alumina ceramic rau lub hau kawg hlau thiab phaj phaj, tsim ib qho chaw kaw tag nrho los ntawm cov cua sab nraud. Sab hauv inert lossis txo cov roj ib puag ncig tsis tsuas yog tua cov arc zoo xwb, tab sis qhov tseem ceeb tshaj, muab qhov ruaj khov thiab siab -dielectric- lub zog insulating nruab nrab. Nyob rau hauv - ntsuas kev khiav hauj lwm voltage, qhov sib chwv qhov sib txawv, thiab qhov kev ncua deb ntawm cov neeg sib cuag thiab cov vaj tse nyob ntawm qhov deb ntawm qhov nruab nrab ntawm cov roj nruab nrab thiab cov phab ntsa ceramic kom tiv taus qhov hluav taws xob. Cov qauv kaw no tiv thaiv kev xeb ncaj qha ntawm cov rwb thaiv tsev los ntawm kev ya raws sab nraud, tshuaj tsuag ntsev, thiab cov plua plav tawm, tso cai rau cov khoom siv hluav taws xob kom muaj kev tiv thaiv hluav taws xob siab thiab tiv taus cov qib hluav taws xob txawm tias nyob rau hauv tsheb- qib kub hloov pauv thiab cov khoom siv vibration.
Cov pa tawm hauv cov kab noj hniav feem ntau yog los ntawm cov kab nrib pleb me me ntawm cov khoom siv ceramic -hlau sealing interface los yog nthuav dav ntawm cov qhov hws nyob rau hauv thermal cycling stress. Thaum pib qhov xau yog qhov tsawg heev, thiab kev sib pauv roj tsuas yog tshwm sim thaum muaj kev hloov pauv loj hauv huab cua sab nraud lossis qhov kub thiab txias. Thaum lub foob tsis ua haujlwm tshwm sim hauv EV Alumina Ceramic Housing, huab cua sab nraud yuav nkag mus, ua rau muaj qhov tsis zoo nyob rau hauv cov muaj pes tsawg leeg thiab purity ntawm cov roj sab hauv. Kev nkag mus ntawm cov pa oxygen thiab noo noo yog qhov ua rau txo qis kev ua haujlwm ntawm rwb thaiv tsev. Cov dej molecules adsorb rau ntawm phab ntsa ceramic sab hauv thiab qhov chaw ntawm cov rwb thaiv tsev tiv thaiv, tsim cov yeeb yaj kiab dej tsis muaj zog. Qhov no ho txo cov nplaim hluav taws xob tiv thaiv. Moisture infiltration tseem tuaj yeem ua rau cov rwb thaiv tsev sib cais ntawm cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob kom nqus tau cov dej noo, ntxiv rau qhov txo qis hauv kev tawm tsam.
Lub xub ntiag ntawm cov pa oxygen ua rau cov nyiaj alloy lossis tooj liab-raws li cov ntaub ntawv ntawm cov neeg sib cuag ntau dua rau oxidation nyob rau hauv qhov kub ntawm qhov tawg arc. Lub resulting hlau oxide hais sputter thiab ua raws li cov ceramic sab hauv phab ntsa. Kev sib sau ua ke ntawm cov khoom siv hluav taws xob tuaj yeem tsim txoj hauv kev tawm hauv cov kab noj hniav, uas ua rau muaj kev cuam tshuam los yog tawg thaum lub sij hawm rwb thaiv tsev tiv thaiv qhov ntsuas hluav taws xob. Thaum lub foob kev ncaj ncees ntawm EV Alumina Ceramic Relay Housing raug cuam tshuam, kev ua haujlwm rwb thaiv tsev tau qis zuj zus thiab rov qab tsis zoo, tsis tu ncua cuam tshuam rau kev ua haujlwm ntawm relay kev ntseeg siab thiab kev ua neej.
Vim hais tias sab hauv ntawm cov kab noj hniav tsis pom, thawj qhov xau yog qhov nyuaj rau kev kuaj pom nrog lub ntsej muag macroscopic. Yog li ntawd, siab - rhiab heev helium huab hwm coj spectrometry leak detection feem ntau yog siv nyob rau hauv ntau lawm thiab zoo tswj kom paub meej tias lub foob kev ua tau zoo thiab kuaj xyuas cov pa paug tawm. Rau cov relays twb tau ua haujlwm lawm, kev ntsuas kev tiv thaiv kev tiv thaiv tsis tu ncua yog ib txoj hauv kev tseem ceeb rau kev txheeb xyuas cov teeb meem kev sib khi. Nyob rau hauv tib lub kub thiab av noo tej yam kev mob, yog hais tias lub rwb thaiv tsev tiv thaiv ntawm kev sib cuag los yog nyob rau hauv cov kev sib cuag thiab lub hauv paus qhia ib tug tsis tu ncua kev tshwm sim, thiab lwm yam tseem ceeb tau txiav txim, nws yuav txiav txim siab hais tias lub Metallized Alumina Ceramics rau hluav taws xob Cheebtsam muaj ib tug internal foob tsis ua hauj lwm.
Hauv kev ua haujlwm tiag tiag, yog tias qhov relay lub casing kub yog siab dua li ntawm cov khoom zoo sib xws thaum disconnecting tib lub load, cov roj nruab nrab hauv nruab nrab yuav ua rau tsis zoo, ua rau txo qis arc extinguishing efficiency thiab hloov dua siab tshiab ntawm lub zog arc mus rau hauv tshav kub. Hauv qhov no, kev tiv thaiv kev hloov pauv yuav tsum tau npaj kom sai kom tsis txhob muaj kev puas tsuaj ntawm cov rwb thaiv tsev, ua rau siab -voltage grounding lossis luv - Circuit Court raug mob. Cov Metalized Ceramic Insulating Tubes Metalizating Ceramic Part yog cov kab tseem ceeb ntawm kev tiv thaiv kom ntseeg tau lub sijhawm ntev - rwb thaiv tsev muaj peev xwm ntawm siab -voltage DC relays. Thaum xaiv cov khoom, kev ntseeg siab ntawm cov txheej txheem sealing yuav tsum tau muab qhov tseem ceeb. Thaum lub sijhawm ua haujlwm thiab kev saib xyuas, ib qho kev tiv thaiv kev tiv thaiv kev tiv thaiv yuav tsum tau tsim los tswj cov kev pheej hmoo ntawm rwb thaiv tsev los ntawm kev foob tsis ua haujlwm thaum ntxov, ua kom muaj kev nyab xeeb thiab ruaj khov ua haujlwm ntawm lub zog tshiab siab -voltage systems.
Peb tus kheej- tsim thiab tsimKub Kub Metallized Ceramic Relay Case, vam khom rau mature metallization welding tshuab, boasts zoo heev sealing kev ua tau zoo thiab muaj peev xwm tiv taus qhov kub thiab txias hloov thiab mechanical vibrations.
