Thaum tsim tawm tom ntej- tiam tshiab lub zog tsheb roj teeb pob, photovoltaic zog cia system PCS, los yog nrhiav kev siab - zoo sealing kev daws teeb meem rau siab - qhov kub thiab txias, koj yuav tsum tau nrhiav ib qho kev daws teeb meem uas tuaj yeem ua tau raws li cov cai nruj hauv qab no:
Nws qhov kev ua tau zoo nyob ruaj khov nyob rau hauv qhov kub thiab txias hloov pauv ntawm-50℃txog 200 degree.
Nws muab kev ruaj ntseg rwb thaiv tsev tiv thaiv txawm tias thaum raug kev co, cuam tshuam, thiab ntev compression. Nyob rau hauv cov xwm txheej ntawm thermal runaway los yog hluav taws xob faults, nws zoo tiv thaiv hluav taws los tiv thaiv kev puas tsuaj escalation. Ntxiv mus, cov khoom siv nws tus kheej yog ib puag ncig tus phooj ywg thiab ruaj khov, ua kom cov khoom muaj kev nyab xeeb thoob plaws hauv nws lub neej tag nrho.
Thaum ntsib cov teeb meem no, cov khoom siv insulating zoo li yas, roj hmab, lossis ceramics feem ntau poob qis. Niaj hnub no, peb zoo siab los qhia txog cov khoom siv engineering uas nyiam tshaj plaws -silicone foam- thiab hais txog nws lub zog tseem ceeb: tshwj xeeb thiab txhua yam - nyob ib puag ncig kev ua haujlwm rwb thaiv tsev.
Hluav taws xob rwb thaiv tsev:Ib tug robust dielectric barrier. Silica gel ua npuas ncauj yog ib qho khoom siv hluav taws xob zoo heev.
Siab ntim resistivity: Nws qhov ntim resistivity feem ntau yog li ntawm 10^12 txog 10^15 Ω·cm, qhia tias muaj kev tiv thaiv siab heev rau tam sim no ntws. Qhov no zoo cais cov khoom nyob, tiv thaiv ob qho tib si to thiab luv circuits.
Daim duab qhia qhov ntsuas tus nqi ntawm Volume resistivity rau Sanpu Silicone
High Dielectric zog: Txawm tias nyob rau hauv daim duab zaj duab xis, silica gel ua npuas ncauj board tuaj yeem tiv taus qhov hluav taws xob tawg siab (feem ntau tshaj 10 kV / mm), ua rau nws zoo tagnrho rau cov ntawv thov tseem ceeb xws li insulating gaskets thiab separators hauv high -voltage ib puag ncig. Kev ruaj ntseg yog qhov tseem ceeb: Tsis zoo li ntau cov khoom siv organic uas muaj kev ua haujlwm tsis zoo ntawm dielectric degradation nyob rau hauv siab - qhov kub thiab txias, cov Si-O cov qauv ntawm silica gel molecules tseem ruaj khov heev. Nws cov khoom hluav taws xob rwb thaiv tsev qhia tias tsis muaj kev puas tsuaj nyob rau hauv qhov kub thiab txias, cov av noo siab, los yog siv ntev, ua kom ntev -lub sij hawm, txhim khu kev qha rwb thaiv tsev.
Thermal rwb thaiv tsev thiab cua sov tswj: Ib txoj hauv kev Dual Thaum tham txog kev rwb thaiv tsev, nws yog ib qho tseem ceeb rau kev sib txawv ntawm cov hluav taws xob rwb thaiv tsev thiab thermal rwb thaiv tsev. Cov khoom siv silicone ua npuas ncauj ua tau zoo hauv ob qho tib si.
Exceptional thermal rwb thaiv tsev (tsawg thermal conductivity):Cov qauv foamed tau ntim nrog suav tsis txheeb me me kaw lossis qhib cua npuas, uas ua raws li cov thermal insulators zoo heev. Yog li ntawd, cov khoom siv silicone ua npuas dej feem ntau pom cov thermal conductivity tsawg (0.04-0.08 W / (m·K)), ua rau nws zoo tagnrho thermal rwb thaiv tsev ncoo thiab txheej. Piv txwv li, nyob rau hauv lub hwj chim roj teeb modules, nws ua hauj lwm raws li ob qho tib si insulating txheej ntawm lub hlwb thiab ib tug zoo barrier los tiv thaiv tshav kub hloov ntawm lawv, yog li ncua thermal diffusion.
Thermal Resistance thiab Stability: Cov no yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv silica gel. Lawv tuaj yeem ua haujlwm dhau qhov kub ntawm qhov dav ntawm -60℃txog 200 degree, nrog luv luv -lub sij hawm raug rau qhov kub siab dua. Nyob rau hauv ntau qhov no, cov khoom tseem nkig-dawb, melts-dawb, thiab ntws-dawb, thaum tuav ruaj khov rwb thaiv tsev thiab txhua yam khoom. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev siv rwb thaiv tsev nyob ze qhov chaw kub xws li IGBTs thiab lub zog hluav taws xob.
"Insulation" ntawm Ib puag ncig thiab Chemistry: Tsim Txhua Yam -Kev Tiv Thaiv ib puag ncig.
Hluav taws kub rwb thaiv tsev: Silicone ua npuas ncauj cov ntaub ntawv inherently muaj nplaim taws-cov khoom tiv thaiv, feem ntau ua tau raws li UL94 V-0 tus qauv yam tsis tas yuav muaj cov khoom siv phom sij halogen. Qhov no ua rau muaj kev nyab xeeb tseem ceeb hauv cov khoom siv roj teeb thiab cov khoom siv hluav taws xob, muab lub sijhawm tseem ceeb rau cov lus teb thaum muaj xwm txheej ceev.
Huab cua thiab tshuaj tiv thaiv:Cov silica gel muaj zog tiv thaiv ozone thiab ultraviolet hluav taws xob, thiab tsis yooj yim rau hnub nyoog. Nyob rau tib lub sijhawm, nws muaj kev ua siab ntev rau dej, tshuaj tsuag ntsev thiab ntau yam tshuaj. Qhov tsis pom qhov "insulating" barrier tiv thaiv cov cuab yeej ua haujlwm ruaj khov hauv ib puag ncig hnyav.
Thaum siv silicone ua npuas ncauj ua ib qho kev daws teeb meem, koj tau txais tsis yog ib qho kev tiv thaiv nkaus xwb, tab sis muaj ntau yam kev sib xyaw ua ke.
