Kab lus no piav qhia txog yuav ua li cas UL -94 qhov ntsuas hluav taws xob cuam tshuam txog kev nyab xeeb hluav taws xob hauv siab -voltage hluav taws xob sib dhos, thiab vim li cas cov nplaim hluav taws xob yuav tsum tau ntsuas ua ke nrog dielectric rwb thaiv tsev, kev ruaj ntseg txhua yam, thiab kev ntseeg tau ntev.
Daim duab 1.Cov txheej txheem - theem kev piav qhia ntawm thaj chaw rwb thaiv tsev thiab kev nyab xeeb- qhov cuam tshuam tseem ceeb hauv qhov siab -voltage hluav taws xob sib dhos, qhia txog thaj chaw uas hluav taws xob, tshuab, thiab thermal stresses cuam tshuam dhau UL-94 nplaim taws ntsuas qhov ntsuas.
UL-94 V0 thiab Kev Nyab Xeeb Hluav Taws Xob hauv Cov Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob
Hauv high -voltage electronic systems, hluav taws xob kev nyab xeeb tsis yog txiav txim los ntawm ib qho khoom vaj khoom tsev.
Thaum nplaim hluav taws kub hnyiab yog qhov tseem ceeb, nws yuav tsum tau soj ntsuam ua ke nrog dielectric kev ncaj ncees, txhua yam ruaj khov, thiab ib puag ncig kev ntxhov siab.
Kev faib tawm UL-94 feem ntau hais txog thaum xaiv cov khoom, tab siskev txhais lus tsis raug lawv qhov peev xwm tuaj yeem ua rau muaj kev xav tsis tseeb txog qhov ntev - hluav taws xob kev nyab xeeb.
Dab tsi UL-94 Nplaim ntsuas ntsuas ntsuas
UL-94 yog tus qauv plastics flammability uas ntsuas seb cov ntaub ntawv teb li cas rau qhov qhib nplaim taws nyob rau hauv cov chaw kuaj mob.
Cov ntsiab lus tseem ceeb suav nrog:
- UL-94 ntsuas cov nplaim hluav taws thiab kev tua tus kheej
- Nws uatsis yogntsuas:
- Dielectric zog
- Ib nrab tso tawm tsis kam
- Cov neeg kho tshuab qaug zog hauv qab vibration
Ntawm UL-94 kev faib tawm,V-0feem ntau tau teev tseg rau siab -voltage hluav taws xob sib dhos vim nws cov txheej txheem tua hluav taws nruj heev.
Vim li cas UL-94 V0 Ib Leeg Tsis Muaj Kev Nyab Xeeb Hluav Taws Xob
Nyob rau hauv siab -voltage ib puag ncig, hluav taws xob tsis ua hauj lwm tsis tshua muaj pib nrog combustion.
Hloov chaw, kev ua tsis tiav feem ntau pib los ntawmlocalized dielectric degradation, uas tom qab ntawd yuav nce mus rau hauv thermal lossis nplaim taws-txog cov xwm txheej.
Cov feem pheej pheej hmoo feem ntau suav nrog:
- Concentrated hluav taws xob teb ntawm rwb thaiv tsev interfaces
- Kev vibration-induced mechanical stress
- Thermal cycling ua rau micro- tawg
Cov mechanisms no yogsab nraum qhov kev ntsuam xyuas ntawm UL-94 kuaj, tsis tau lawv ncaj qha cuam tshuam hluav taws xob kev nyab xeeb nyob rau lub sijhawm ntev - ua haujlwm.
Kev sib cuam tshuam ntawm nplaim hluav taws retardancy thiab Dielectric Performance
Cov khoom tsim los ua kom tau raws li cov nplaim taws- cov kev cai retardant tuaj yeem qhia txog kev lag luam tawm - tawm uas cuam tshuam rau kev coj tus cwj pwm.
Piv txwv li:
- Qee cov nplaim taws- cov khoom siv retardant tuaj yeem hloov cov dielectric tsis tu ncua
- Cov ntsiab lus muab tub lim ntxiv tuaj yeem txo cov neeg kho tshuab ua raws
- Cov ntaub ntawv tawv tawv yuav ua rau muaj kev cuam tshuam ntau dua hauv kev vibration
Raws li tau piav qhia hauvDaim duab 2, rwb thaiv tsev tawg feem ntau yog tsav los ntawm kev sib cuam tshuam ntawm hluav taws xob kev ntxhov siab thiab cov neeg kho tshuab deformation es tsis yog hluav taws kub ib leeg.
Daim duab 2.Cov lus piav qhia qhia tau hais tias yuav ua li cas hauv cheeb tsam dielectric kev ntxhov siab thiab cov tshuab deformation cuam tshuam ntawm rwb thaiv tsev cuam tshuam hauv high-voltage electronic assemblies.
Kev Pom Zoo Engineering: Kev nyab xeeb raws li qhov System-Level Outcome
Los ntawm qhov kev xav ntawm engineering, kev nyab xeeb hluav taws xob yuav tsum raug kho raws li ib qhoqhov system- theem cov txiaj ntsig, tsis yog ib qho kev ua raws cai checkbox.
Kev nyab xeeb muaj txiaj ntsig- xaiv cov khoom siv taw qhia suav nrog:
- Nplaim hluav taws kub (UL-94)
- Dielectric rwb thaiv tsev stability
- Kev tiv thaiv kev vibration- ua rau muaj kev ntxhov siab
- Ntev -lub sij hawm ib puag ncig durability
Cov kab ke no-raws li txoj hauv kev sib haum nrog tib lub tswv yim engineering uas tau tham hauvkev vibration{0}}induced dielectric tsis ua hauj lwm mechanisms🔗
Kev xaiv cov khoom siv rau siab -Voltage Safety
Thaum ntsuas cov rwb thaiv tsev thiab cov ntaub ntawv tiv thaiv rau siab -voltage assemblies, engineers yuav tsum xyuas kom meej tias:
- nplaim retardancy tsis cuam tshuam lub zog dielectric
- Mechanical ua raws li kev txhawb nqa kev vibration mitigation
- Tus cwj pwm ntawm cov khoom tseem nyob ruaj khov nyob rau lub sijhawm ua haujlwm ntev
Hauv cov ntsiab lus no,RTV silicone cov ntaub ntawv feem ntau raug soj ntsuam vim lawv qhov yooj yooj yim thiab cov yam ntxwv insulating🔗
