Lub cev muajeric lub cev rau cov kev paub folding

Hauv kev tiv thaiv hluav taws xob tshiab, lub cev ceramic rau lub fuse cov rooj sib xyaw ua ke ua lub fuse "kev tiv thaiv tseem ceeb uas muab cov kev ua tiav rwb thaiv tsev, thiab lub zog kho tshuab. Los ntawm cov hluav taws xob siab ntawm cov hluav taws xob tsheb mus rau lub DC cov hluav taws xob cia, nws kev ua tau zoo ncaj ncees thiab kev tiv thaiv kev ntseeg tau. Cov tshuaj ntsuam hauv qab no tseem ceeb tshaj plaws hauv qab no thiab cov ntsiab lus tseem ceeb ntawm cov khoom siv, kev ua tau zoo logic, thiab thev naus laus zis sib txawv.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cov khoom xaiv rau lub cev ceramic rau Siemens LV yuav tsum ua kom tau raws li kev "rwb thaiv tsev ua ntej, thiab muaj zog li lub hauv paus." Qhov no txiav txim siab nws tus tseem ceeb tus nqi hauv cov pej xeem hluav taws xob ib puag ncig. The industry mainstream uses 95% alumina ceramics and beryllium oxide ceramics as substrates. Cov no ob cov ntaub ntawv tsim cov kev daws teeb meem zoo. Alumina Ceramics (Al₂o₃), nrog ib lub rwb thaiv tsev tsis kam tshaj 1000mω thiab kev xaiv flexural thiab kev xaiv zoo tshaj plaws rau kev sib npaug thiab cov khoom siv neeg kho tshuab. Nyob rau hauv lub high-voltage roj teeb hluav taws xob ntawm hluav taws xob tsheb, nws rwb thaiv tsev tsis ntseeg siab dua lossis muaj sib npaug ntawm 1000,000 qhov kev nyab xeeb. Beryllium oxide ceramics (boo), nrog lub siab thermal conductivity, kwv yees li ntawm alumina), yog haum rau kev tawm tsam sai sai ntawm lub sij hawm ntawm lub caij nyoog nce nyob rau hauv lub sij hawm ntawm lub sij hawm ntawm lub sij hawm ntawm lub sij hawm nce nyob rau hauv lub sij hawm 50 degree. Cov Khoom Siv Purity thiab Sintering Txheej Txheem Ncaj Ncees Ncaj Ncees Tsis Txaus Siab: EF Ceramic lub cev yuav tsum muaj ntau tshaj 3.85g / cm³, kom meej meej rwb thaiv tsev tsis kam ruaj khov. Beryllium oxide ceramics yuav tsum muaj cov ntsiab lus tsis huv ntawm tsawg dua lossis sib npaug nrog 0.5% los tiv thaiv cov kev ua haujlwm thermal vim yog cov tawv nqaij tawv. Kev kho deg kuj tseem yog qhov tseem ceeb. Precision sib tsoo (roughness ra tsawg dua los yog sib npaug rau cov ntawv thov hluav taws xob kev nyab xeeb (xws li cirolage cov ntawv thov (xws li cirvulits saum 400v).

 

 

Qhov kev ua tau zoo ntsuas kev tsim ntawm lub ceramic lub cev rau cov hluav taws xob ua kom sib haum nrog cov kev siv hluav taws xob ntawm cov kev siv hauv qab, sib sau cov phiaj xwm kho kom meej. Lub rwb thaiv tsev tsis kam yuav tsum muaj ntau dua los yog sib npaug ntawm 1000mω stems los ntawm kev nyab xeeb refundancy yuav tsum muaj ntawm voltage ntau. Hauv cov hluav taws xob cia hluav taws xob cia hluav taws xob cov khoom siv (hauv qab 36V), ib qho rwb thaiv tsev tsis kam ntawm 1000mω khaws cia li no hauv qab 0.036μa. Nyob rau hauv lub high-voltage circuits ntawm hluav taws xob tsheb (800v), ib qho kev tawm dag zog tiv thaiv 1500mω lossis siab dua rau 0.5μa kom tsis txhob muaj kev pheej hmoo ntawm hluav taws xob ntawm hluav taws xob.

 

Tus qauv tsim qauv ntawm voltage withst zog (xws li volts rau ob peb txhiab volts) xav txog kev xav txog ntau yam. Cov kev tswj hwm hnub ci siv 500v withstand voltage ceramics, uas dhau ib lub zog ntawm 1 feeb nrog kev ntsuas voltage yam tsis tau tawg. Lub ntsiab hluav taws xob loj hluav taws xob ntawm lub tsheb hluav taws xob yuav tsum muaj 3000V withstand voltage rating los tuav rwb thaiv tsev rwb thaiv tsev nyob rau hauv 10KV SURGE Voltage. Cov ntsuas kub tsis kam ntau (-qib degree) kuj hais txog cov khoom siv rau sab hnub tuaj Lub cev fuse lub cev rau hluav taws xob tsheb ua ke nyob ze rau ntawm lub cav hluav taws xob muaj zog (thermal expansion tsawg dua lossis sib npaug zos ua haujlwm ntawm kev ua haujlwm ntev ntawm 150 degree.

 

Cov neeg kho tshuab zog tsim cov nqi hnyav thiab kev tiv thaiv me me rau kev siv lub zog loj dua lossis muaj kev sib luag ntawm cov khoom siv hluav taws xob ntau dua lossis muaj 5 hli saum toj no Cov Cheebtsam muaj ntau lub ceramic (20mm diam

 

Cov kev xav tau kev ua tau zoo rau cov ceramic casing rau kev sib txuas hauv cov cim fuse hauv cov khoom sib txawv tshiab, tsav lub tshuab ua kom zoo dua tshiab ntawm cov khoom thev naus laus zis. Nyob rau hauv lub chaw ntim khoom hluav taws xob, cov kev cai tseem ceeb yog "High-voltage rwb thaiv tsev (PDU) yuav tsum dhau 3000 Siv Alumina Ceramic Nrog Hlau Kawg Cap Vuam Txheej Txheem (Vuam Lub Zog Loj dua los yog sib npaug rau 100n) tuaj yeem txo tus nqi tsis ua haujlwm rau 0.01% ib xyoos.

PV lub zog cia cov tshuab ua ntej "huab cua tsis kam + thermal stability": tusCeramic rau Fais thiab hybrid Tsheb FusedNtawm DC-sab fuse hauv Central inverlicers yuav tsum muaj lub rwb thaiv tsev tsis kam lossis sib npaug rau 105℃mus rau 85 degree. Lub siab thermal conductivity ntawm beryllium oxide ceramic luv luv tom qab tau yaj mus tsawg dua 1 Thib ob, tiv thaiv arc reignition. Faib hluav taws xob cia khoom siv Alumina Ceramic nrog nano-txheej, ua kom haum rau cov pej xeem noo noo. Cov ntsiab lus tseem ceeb rau cov khoom siv hluav taws xob tshiab (xws li cov khoom siv hluav taws xob sab nraum zoov) yog "miniaturization + tus nqi qis." Siv 90% Alumina Ceramic (15% Tus nqi qis dua 95% qauv), cov khoom no tau ua tiav me me 5mm X 3mm X 3mm X 3mm hneev taw los ntawm kev txhaj tshuaj txhaj tshuaj molding. Nws tseem tswj hwm cov rwb thaiv tsev tsis kam ntawm ntau dua los yog sib luag rau 1000mω, ntsib kev tiv thaiv kev txwv ntawm cov voj voog qis dua 100V.
