20W Waterproof Ib Leeg Tso Tawm Hloov Fais Fab LPV-20 series
Nyob rau hauv tus txheej txheem ntawm kev siv lub waterproof switching fais fab mov, thawj yam uas engineers yuav tsum tau them sai sai rau yog tus kheej-kub ntawm lub switching fais fab mov.Feem ntau, qhov kub ntawm cov khoom siv hluav taws xob zoo dua uas tau piav qhia los ntawm cov khoom siv hluav taws xob yuav raug khaws cia ntawm li 25-30 ° C, thaum qhov kub nce siab ntawm cov duab tsis zoo yuav ntau dua 35 ° C.Lub tshuab hluav taws xob hloov hluav taws xob siv nyob rau hauv cov teeb pom kev zoo rau pej xeem thiab qhov chaw teeb pom kev zoo sab nraum zoov yuav tsum tsis muaj dej tsis muaj dej, thiab yuav tsum muaj lub kaw lus kaw.Txhawm rau txhim kho qib kev tiv thaiv, cov chaw tsim khoom yuav tsum tau sau cov kua nplaum.Tus nqi ntawm cov khoom sib txawv colloidal sib txawv, thiab cov khoom siv hluav taws xob ua kom sov kuj sib txawv, uas yog pheej yig.Kev muag cov kua nplaum muaj cov thermal conductivity tsis zoo thiab yuav tsum tau ua kom kub kub, uas feem ntau ua rau pom kev puas tsuaj thiab nruj ntawm cov khoom sib txawv ntawm cov khoom sib txawv, ua rau muaj kev phom sij.
Qhov kub ntawm tus kheej ntawm cov teeb thiab cov teeb ci tseem yog ib qho teeb meem loj uas yuav tsum tau them sai sai rau thaum cov dej hloov hluav taws xob hloov hluav taws xob siv rau hauv cov teeb pom kev zoo rau pej xeem, vim tias cov cua kub ntau yog nyob ntawm lub plhaub kom dissipate cua sov.Nws yog tsim nyog los piav txog lub teeb.Qhov kub ntawm lub plhaub nws tus kheej yog li ntawm 20 ℃ -25 ℃.Qhov ntawd yog hais tias, nws yog ib txwm zoo rau lub teeb vaj tsev kub txog li 45 ° C-50 ° C nyob rau hauv kev khiav hauj lwm ntawm chav tsev kub 25 ° C.Yog tias nws tshaj qhov ntsuas ntawm qhov ntsuas no, nws txhais tau tias cov khoom muaj qhov tsis xws luag hauv qhov kub thiab txias.
Ib qho teeb meem uas yuav tsum tau muab sau tseg ntawm no yog tias thaum ua haujlwm, txhua zaus qhov kub ntawm electrolytic capacitor ntawm lub zog hloov hluav taws xob nce 10 ° C, lub neej ntev yuav raug txo qis, uas yuav cuam tshuam ncaj qha rau nws lub neej kev pab cuam.Tam sim no, cov neeg ua haujlwm muaj feem cuam tshuam hauv Suav teb tau thov seb puas muaj cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob tuaj yeem siv rau hauv thaj chaw teeb pom kev zoo.Txawm li cas los xij, nrog cov cuab yeej siv hluav taws xob tam sim no, ob qho ntawm ob hom capacitors tsis tuaj yeem ua rau hauv high-voltage thiab loj-muaj peev xwm, uas yog qhov tu siab heev.Txawm li cas los xij, kev siv cov capacitor ntev ntev yuav tsis ua kom lub zog lub neej.Txhawm rau txhim kho lub zog lub neej, kev txhim kho yuav tsum tau ua ntau txoj hauv kev, xws li siv cov capacitors nrog lub neej ntev dua, ua kom lub zog siv hluav taws xob ntau dua, ua kom lub zog hluav taws xob zoo dua, los yog teeb pom kev zoo, thiab lwm yam.
