Qhov tseem ceeb ntawm High-voltage cov ntaub ntawv hlau hauv cov tsheb hluav taws xob

1. Pib

Cov tsheb hluav taws xob (EVS) tau hloov txoj kev uas peb taug kev, muab cov tsheb sib xyaw ua ke rau cov roj tsoos ua ke. Tab sis tom qab tus nrawm nrawm thiab kev ua haujlwm ntsiag to ntawm cov lus dag uas tseem ceeb heev uas feem ntau mus tsis pom-High-voltage cov xov hlauCov. Cov xov hlau no yog lub luag haujlwm rau kev xa cov hluav taws xob ntawm lub roj teeb, lub cev muaj zog, thiab ntau yam hluav taws xob, ua yeeb yam raws li covtxoj kevntawm lub tsheb lub zog.

Raws li Evs tau ua ntau dua, qhov xav tau ntawm cov tshuab hluav taws xob siab yog nce. Kev Nyab Xeeb, Ua Haujlwm, thiab Durability yog kev txiav txim siab tseem ceeb, ua cov khoom lag luam xaiv ib qho tseem ceeb. Yog li, cov ntaub ntawv twg yog qhov zoo tshaj plaws rau high-voltage ev hlau? Cia peb tawg nws.

2. Hom High-Voltage Hlau Rwb Thaiv Tsev Cov Ntaub Ntawv

Txhawm rau kom muaj kev nyab xeeb thiab kev ua haujlwm tau zoo, cov xov hlau siab yuav tsum yogInsulatedNrog cov khoom siv zoo uas tuaj yeem tiv thaiv kom sov, kev ntxhov siab, thiab cov kev sib tw ib puag ncig. Nov yog cov ntaub ntawv rwb thaiv tsev tshaj plaws siv hauv cov xov hlau siab:

2.1. Polyvinyl chloride (PVC)

PVC yog ib zaug siv dav vim nwsTus nqi qis thiab cov khoom siv zooCov. Nws yooj yim rau cov txheej txheem thiab muaj cov kev ua haujlwm ruaj khov. Txawm li cas los xij, pvc muaj qee qhov kev txiav txim siab tseem ceeb:

• Nws muaj cov chlorine, uas ua rau muaj kev phom sij rau ib puag ncig thiab tib neeg kev noj qab haus huv.
• Nws muaj cov cua sov tsis zoo, uas tuaj yeem ua rau muaj kev mob siab nyob rau hauv qhov kub.
• Nws yog qhov nyuaj rau cov tawv thiab tawg tag nrho, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej huab.

Vim tias cov teeb meem no, muaj ntau cov tuam ntxhab txav deb ntawm PVC hauv kev nyiam cov ntaub ntawv siab dua.

2.2. Hla-Txuas Polyolefin (XLAPO)

XLO yog ib qho ntawm cov kev xaiv sab saum toj rau high-voltage ev hlau. Ntawm no yog vim li cas:

• Zoo tshaj cua kub tiv:Nws tuaj yeem tiv taus ntau qhov kub thiab txias yam tsis muaj kev nyab xeeb.
• Zoo heev Txhua Yam Muaj Zog:Tiv taus khoov, ncab, thiab kev cuam tshuam.
• Qhov ruaj khov:Ntev lifespan ntev vim nws tsis kam mus rau kev laus thiab hnav.
• Tshuaj lom neeg ruaj khov:Resistant rau corrosion thiab harsh ib puag ncig.

Ib lub drawback yog nwsCov nplaim taws tsis muaj zog, tab sis Halogen-dawb nplaim-retardant XLPO feem ntau siv los daws qhov teeb meem no. Vim tias nws cov kev ua tau zoo, XLO tam sim no yog qhov kev xaiv thawj rau cov xov hlau siab.

2.3. Thermoplastic elastomer (TPE)

TPE yog qhov hloov tau yooj yim thiab yooj yim-ua ke uas ua ke cov khoom ntawm roj hmab thiab yas. Nws muaj:

• Elasticity zoontawm qhov chaw kub qub.
• Lam txawj pobzeb, ua rau nws yooj yim kom haum rau hauv cov qauv xov hlau sib txawv.

Txawm li cas los xij, nws muaj qee qhov tsis muaj zog:

• Qis dua coj tsis kampiv rau XLO.
• Kev ua hauj lwm qis dua-kub ua tau, ua rau nws tsim nyog dua rau kev xav tau cov chaw EV.

Vim tias cov kev txwv no, TPE tsis yog qhov kev xaiv zoo tshaj plaws rau cov xov hlau high-volting tab sis tseem siv nyob rau qee cov kev siv.

3. Cov Qauv rau EV High-Voltage Cov Xov

Txhawm rau kom muaj kev nyab xeeb thiab kev ntseeg tau, cov xov hlau siab hauv EVS yuav tsum ua kom tiav cov qauv kev lag luam nruj. Nov yog qee qhov ntawm cov qauv tseem ceeb tau siv thoob ntiaj teb:

Cov Qauv Thoob Ntiaj Teb:

• IC tus qauv: Npog hluav taws xob, mechanical, thiab thermal khoom.
• ISO Cov Qauv:
  • ISO 19642: Tsom rau ntawm txoj kev tsheb cable.
  • ISO 6722: Npog cov roj voltage tsawg tab sis qee zaum tau hais txog hauv EV daim ntawv thov.

Suav Teb Qauv:

• QC / T 1037: Tswj cov tshuab hluav taws xob high-voltage cables rau lub zog tshiab.
• CQC 1122: Tsom mus rau ev phev cables.

Lwm cov ntawv pov thawj:

• LV216: German Automotive txheem.
• Dekra K179: Cov ntaub ntawv sim hluav taws kub tsis kam thiab kev nyab xeeb hluav taws.

4. Cov kev ua tau tseem ceeb yuav tsum muaj

High-voltage cables yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua kom ntseeg tau tias muaj kev nyab xeeb thiab txhim khu kev qha ua haujlwm hauv evs. Cia peb saib ntawm qhov tseem ceeb ua tau zoo:

4.1. Kev Ua Hluav Taws Xob Hluav Taws Xob

• Cov Kev Ntsuas Cov Ntev Hluav Taws Xob thiab Loj Tam Sim No: Ev high-volultage Systems feem ntau ua haujlwm ntawm400v rau 800v, xav tau cables nrogCov rwb thaiv tsev zoo heev.
• Tiv thaiv cov hluav taws xob xau: Cov rwb thaiv tsev txom nyem tuaj yeem ua rauLub zog poob lossis txawm tias muaj kev phom sij luv luv.
• Withstands Kev Nyuaj Siab Loj Siab: Raws li lub roj teeb Ev voltage nce, cables yuav tsum tau tiv thaiv hluav taws xob tawg.

4.2. Kev ua yeeb yam ntawm lub cev

• Thaum Tshav Kub Kub Ua: Thaumceev them los yog kev tsav tsheb siab, cov xov xwm yuav tsum witand kom muaj qhov kub thiab tsis muaj melting lossis kev poob qis.
• Txias tsis taus: Nyob rau hauvCia mob, cov rwb thaiv tsev yuav tsum nyob twj ywm thiab tsis tau nkig.
• Yooj yooj: Cables yuav tsum khoov thiab txoj hauv kev yooj yim thaum lub sijhawm teeb tsa thiab kev ua haujlwm.
• Neeg Kho Tshuab Muaj Zog: Xov xwm yuav muaj nyiaj kom thev dhauKev co, cuam tshuam, thiab ncabtsis muaj kev sib tsoo lossis poob.

4.3. Tshuaj lom neeg

• Roj thiab kua dej tsis kam: Yuav tsum muaj kev tiv thaiv kom pom tseebLubricants, Roj Roj Roj Electrolytes, thiab lwm cov kua roj tsheb.
• Corrosion Kuj: Tiv thaiv kev puas tsuaj los ntawmTshuaj lom neeg thiab khoom siv hluav taws xob ib puag ncig.

5. Yav Tom Ntej Tiam thiab Kev Tsim Kho

Kev txhim kho ntawmTom ntej-tiamHigh-voltage cov ntaub ntawv yog ib txheej txheem txuas ntxiv. Ntawm no yog lub neej tom ntej zoo li cas:

• Ntau dua tam sim no-nqa muaj peev xwm: Raws liRoj teeb voltages nce, cables yuav tsum txhawb nqaTxawm cov qib siab dua.
• Zoo dua kub tiv: Cov Khoom Siv Tshiab YuavKev kov cov kubTxawm tias zoo dua li hnub no XLO.
• Muaj zog: Kev lag luam yog hloov mus rauCov Khoom Siv Hauv Ib Pausuas txo cov pa phem thiab txhim kho rov ua dua tshiab.
• Txhim Kho Hluav Taws Kub Kev Nyab Xeeb: Cov rwb thaiv tsev tshiab yuav muajzoo dua nplaim tawstsis muaj tshuaj lom neeg.
• Ua Ntej Raug: Nrhav hauvExtrusion thiab ua cov txheej txheemYuav txhim khu cable kev ua tau zoo thaum txo tus nqi ntau lawm.
