Yuav Ua Li Cas Xaiv HV Connectors thiab Harnesses rau Lub Tsheb Hluav Taws Xob
Automotive high-voltage wiring harness (high-voltage cables and high-voltage interfaces) yog ib qho tseem ceeb ntawm cov hluav taws xob hluav taws xob, muab kev lag luam txhim khu kev qha thiab kev nyab xeeb ntawm cov tsheb hluav taws xob. Lub ntsiab kev txhim kho thiab tsim kev daws teeb meem rau tag nrho lub tsheb high-voltage harness koom nrog cable layout, cable inch xaiv, high-voltage connector xaiv, them cable thiab interface hom thiab daim ntaub ntawv, cable kho thiab tiv thaiv, thiab lwm yam.
Tag nrho lub tsheb Layout ntawm High Voltage Harness
Qhov kev sib txuas hluav taws xob siab sib txuas ntawm txhua qhov hluav taws xob siab, xws li lub roj teeb rau PDU, lub cev muaj zog rau lub cev muaj zog, AC / DC them, thiab lwm yam, yog qhov tsim nyog los ntawm qhov chaw teeb tsa ntawm cov khoom siv hluav taws xob siab ntawm lub tsheb hluav taws xob.
Yog hais tias lub high-voltage hlau harness yuav tsum dhau los ntawm lub ntse ntug ntawm lub qhov, yuav tsum tsim tus coj kev tiv thaiv qauv. Hauv kev txhim kho lub tsheb thaum ntxov, kev teeb tsa yuav tsum tau sim kom tsis txhob muaj qhov kub ntawm qhov chaw vibration; txwv tsis pub, nws yuav tsum tau khaws cia ntawm qhov deb txaus. High-voltage wire harnesses muaj qhov loj sab nraud thiab qhov hnyav. Txhawm rau kom tsis txhob muaj kev ntxhov siab, qhov tsawg tshaj plaws khoov lub vojvoog ntawm cov kab hluav taws xob feem ntau yog ntau dua li txoj kab uas hla ntawm txoj kab uas hla ntawm 5 npaug.
Yuav kom faib cov load kom tsim nyog, qhov yuav tsum tau ua kom muaj kev txhawb nqa ntawm kev txhim kho ruaj khov. Hlau hlua txoj kab ncaj nraim ntawm cov ntsiab lus ruaj khov ≤ 300mm; dhau qhov khoov khoov, cov ntsiab lus ruaj khov yog tsau ntawm ob qhov kawg ntawm qhov arc. Tsau taw tes thiab qhov sib txuas sib txuas ≤ 150mm kom tiv taus qhov hnyav ntawm lub sam xauv nees thiab kev vibration load.
Cov cuab yeej kho yuav tsum siv cov tsheb-qib ties thiab insulated brackets, thiab lwm yam. Lub tshuab tsav tsheb yuav tsum xav txog qhov cuam tshuam ntawm kev tiv thaiv kev txav thiab kev co. Lub sam xauv nees loj yuav tsum tsim nyog tsim los ua kom tau raws li cov kev ntxhov siab uas tau muab faib rau hauv qhov ntev thiab tsis txhob siv hlua khi vim ntev ntev. Rau cov hlau hlua txav, ua kom cov roj hmab nplhaib cushion thiab qhia qhov ruaj khov qauv kom tsis txhob txiav cov hlua hlau thiab lwm yam khoom, ua rau muaj kev puas tsuaj rau cov hlua hlau.
Cov ntsiab lus hauv qab no yuav tsum tau txiav txim siab thaum lub sij hawm xaim hlua teeb
Xav txog EMC electromagnetic cuam tshuam yam, shielded high-voltage cables yog siv kom tsis txhob muaj suab nrov nrov emission. Cov kab hluav taws xob siab thiab qis hluav taws xob yuav tsum tau teem caij sib cais kom tsis txhob muaj kev cuam tshuam los ntawm kev sib tshooj sib tshooj.
Xav txog qhov zoo nkauj ntawm txoj hlua khi, kev taw qhia yuav tsum ua raws li cov kev taw qhia ntawm qhov chaw nyob kom tsis txhob oblique kev taw qhia. Rau cov plaub hau cab hlua hlua hlua, kom deb li deb tau nyob rau hauv cov txheej txheem los yog cov khoom hauv qab no los yog nyob rau hauv kev sib raug zoo, lub hauv qab ntawm tag nrho cov tsheb raug high-voltage thaiv hlua siv cov yeeb nkab tiv thaiv thiab ib tug shielding phaj rau shielding tiv thaiv.
Xav txog kev txhim kho thiab tswj xyuas tib yam ntawm cov khoom sib txuas kom tsis txhob muaj kev cuam tshuam tsis zoo los ntawm kev xaiv qhov sib txawv ntawm qhov sib txawv thiab txoj hauv kev tso rau qhov txuas. Qhov kawg ntawm lub connector yuav tsum tau tawm ib qho nyiaj ntawm cov npoo rau ntsaws.
Xav txog kev nyab xeeb ntawm high-voltage. Qhov hluav taws xob high-voltage no tau dhau ntawm tib neeg lub cev kev nyab xeeb voltage. Lub cev tsis tuaj yeem ua tau zoo ib yam li qhov qis-voltage system ntawm hitch. Nws yuav tsum tau siv ib tug dual-track system.
High Voltage Cable Xaiv
Txoj kab uas hla yog raws li qhov teeb tsa ntawm txhua qhov hluav taws xob hluav taws xob siab ntawm lub tsheb kom paub qhov txawv ntawm lub ntsiab Circuit Court thiab ceg Circuit Court. Thiab txhawm rau txiav txim siab cov yam ntxwv ntawm cov khoom siv hluav taws xob hluav taws xob txuas nrog cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob.
Cov yam ntxwv muaj xws li kev khiav hauj lwm voltage, ntsuas lub zog, lub zog siab tshaj plaws, ntsuas tam sim no, ncov tam sim no, lub sijhawm, thiab lwm yam. Kev khiav hauj lwm kub thiab qhov kub thiab txias kuj cuam tshuam rau txoj kab uas hla. Txij li kev sib kis tau zoo tam sim no tuaj yeem ua rau muaj kev siv hluav taws xob ntau thiab cov khoom sib txuas kom nce qhov kub thiab txias, yog li qhov kev tsim hluav taws xob high-voltage cable yuav tsum tiv taus qhov kub thiab txias. Yog hais tias lub cable yog teem nyob rau hauv ib puag ncig uas siab tshaj qhov tso cai rau kev khiav hauj lwm kub ntawm lub cable, ib tug cable nrog ib tug loj cross-sectional cheeb tsam yuav tsum tau xaiv.
Rau Tmax mus txog 180 ℃, tus neeg xyuas pib hla ntu yuav siv rau hauv ib qho thaiv. 250 ℃ Tmax yog tus neeg xyuas pib hla ntu ntu siv hauv ob qhov thaiv. Cable qauv High-voltage cables muab faib ua ib leeg-core cables thiab multi-core cables. High-voltage cables yog puag ncig hauv ntu ntu thiab muaj xim txiv kab ntxwv xim. Multi-core cables yog tsim los ntawm ntau cov tub ntxhais ib leeg. Single-core cables yuav tsum tau ua raws li cov txheej txheem kev tsis sib xws ntawm ib leeg-core cables. Thiab yog tias cov tub ntxhais ntau lub cable siv rau cov teeb liab kis tau tus mob, thov siv cov ntaub thaiv npog cais kom ntseeg tau tias lub teeb liab tsis ploj.
Tus neeg xyuas pib feem ntau yog siv ntau cov tub ntxhais mos tooj liab-stranded hlau kom tau raws li cov kev cai ntawm cov hlau sab hauv tsis kam thiab muag muag degree. Cov txheej rwb thaiv tsev yuav tsum tiv taus qhov kub thiab txias thiab nplaim hluav taws, feem ntau cov qauv sib xyaw. Rau EMC kev tiv thaiv, lub high-voltage cable nrog ib tug shielding txheej siv liab qab tooj liab los yog tooj liab-plated hlau braided nyob rau hauv lub puab sheath txheej nrog ib tug braiding ceev ntawm ≥ 90%.
