Hauv thaj chaw ntawm Cov Tsheb Siv Hluav Taws Xob Tshiab (EV, PHEV, HEV), kev xaiv cov ntaub ntawv rau cov xov hluav taws xob siab yog qhov tseem ceeb rau lub tsheb txoj kev nyab xeeb, kev ruaj khov, thiab kev ua tau zoo. Cov polyethylene txuas (XLPE) thiab roj hmab silicone yog ob qho ntawm cov ntaub ntawv rwb thaiv tsev feem ntau, tab sis lawv muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm kub siab, cov khoom rwb thaiv tsev, lub zog kho tshuab, thiab ntau ntxiv.
Zuag qhia tag nrho, ob qho tib siXLPEthiab cov roj hmab silicone yog siv dav hauv cov xov hluav taws xob sab hauv tsheb. Yog li, cov khoom siv twg zoo dua rau cov xov hluav taws xob siab hauv cov tsheb fais fab tshiab?
Vim li cas cov Cables High Voltage rau cov tsheb fais fab tshiab thiaj xav tau cov khoom siv rwb thaiv tsev zoo?
Cov xov hluav taws xob siab hauv cov tsheb fais fab tshiab feem ntau yog siv rau lub roj teeb, lub cev muaj zog, lub kaw lus tswj hwm hluav taws xob, thiab lub kaw lus them, nrog rau cov hluav taws xob ua haujlwm txij li 600V txog 1500V, lossis siab dua.
Qhov no yuav tsum tau cov cables muaj:
1) Kev ua haujlwm rwb thaiv tsev zoo heev los tiv thaiv kev puas tsuaj hluav taws xob thiab xyuas kom muaj kev nyab xeeb.
2) Kev tiv taus kub siab zoo heev kom tiv taus qhov chaw ua haujlwm hnyav thiab tiv thaiv kev puas tsuaj ntawm cov rwb thaiv tsev.
3) Muaj zog tiv taus kev ntxhov siab ntawm cov khoom siv kho tshuab, khoov, co, thiab hnav.
4) Kev tiv thaiv xeb zoo rau cov tshuaj lom neeg kom hloov kho rau cov chaw nyuaj thiab txuas ntxiv lub neej kev pabcuam.
Tam sim no, cov txheej rwb thaiv tsev ntawm cov xov hluav taws xob siab hauv cov tsheb fais fab tshiab feem ntau siv XLPE lossis roj hmab silicone. Hauv qab no, peb yuav ua qhov kev sib piv ntxaws ntxaws ntawm ob cov ntaub ntawv no.
Los ntawm lub rooj, nws tuaj yeem pom tias XLPE ua tau zoo dua ntawm kev tiv thaiv hluav taws xob, lub zog kho tshuab, kev laus tiv taus, thiab kev tswj tus nqi, thaum roj hmab silicone muaj qhov zoo hauv kev tiv thaiv kub thiab yooj ywm.
Vim li cas XLPE thiaj yog cov khoom siv zoo tshaj plaws rau cov xaim hluav taws xob siab hauv cov tsheb fais fab tshiab?
1) Kev Ua Haujlwm Rwb Thaiv Zoo Dua: Cov khoom siv rwb thaiv tsev XLPE muaj lub zog dielectric siab dua (≥30kV / hli), uas ua rau nws zoo dua ntawm kev tiv taus kev pheej hmoo ntawm hluav taws xob tawg hauv qhov chaw muaj hluav taws xob siab piv rau cov roj hmab silicone. Tsis tas li ntawd, cov khoom siv rwb thaiv tsev XLPE muaj qhov poob dielectric qis, ua kom muaj kev ua haujlwm ruaj khov mus sij hawm ntev, ua rau nws tsim nyog rau cov tshuab fais fab tsheb tshiab.
2) Cov Khoom Siv Kho Tshuab Zoo Dua: Thaum tsav tsheb, kev co ntawm lub cev tsheb tuaj yeem ua rau muaj kev ntxhov siab rau cov xov hlau. XLPE muaj lub zog tensile siab dua, tiv taus kev hnav zoo dua, thiab tiv taus kev txiav zoo dua, ua rau nws tsim nyog dua rau kev siv mus sij hawm ntev thiab txo cov nqi txij nkawm piv rau roj hmab silicone.
3) Kev Tiv Thaiv Kev Laus Zoo Dua: Cov khoom siv rwb thaiv tsev XLPE muaj kev tiv thaiv zoo heev rau kev laus ntawm cov ntoo dej, ua kom ntseeg tau tias cov xov hlau tseem ruaj khov hauv cov av noo siab thiab cov chaw muaj hluav taws xob siab. Qhov no yog qhov tseem ceeb rau cov tsheb siv hluav taws xob tshiab, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov siab xws li cov roj teeb hluav taws xob siab thiab cov tshuab them ceev.
4) Kev Ywj Pheej Nruab Nrab Kom Ua Tau Raws Li Cov Kev Xav Tau ntawm Cov Xov Hlau: Piv rau cov roj hmab silicone, XLPE muaj kev ywj pheej nruab nrab, sib npaug kev ywj pheej ntawm cov xov hlau thiab lub zog kho tshuab. Nws ua tau zoo heev hauv cov ntawv thov xws li cov hlua hluav taws xob siab hauv tsheb, cov kab tswj lub cev muaj zog, thiab kev sib txuas ntawm cov roj teeb.
5) Siv Nyiaj Ntau Dua: XLPE siv nyiaj ntau dua li roj hmab silicone, txhawb kev tsim khoom loj. Nws tau dhau los ua cov khoom siv tseem ceeb rau cov xov hluav taws xob siab hauv cov tsheb fais fab tshiab.
Kev Tshawb Fawb Txog Daim Ntawv Thov: XLPE vs Silicone Rubber
XLPE, nrog nws qhov kev tiv thaiv hluav taws xob zoo heev, lub zog kho tshuab, thiab qhov zoo ntawm tus nqi, muaj kev sib tw ntau dua hauv kev siv cov xov hluav taws xob siab rau cov tsheb fais fab tshiab.
Raws li kev siv tshuab tsheb fais fab tshiab txuas ntxiv mus, cov ntaub ntawv XLPE kuj tseem raug hloov kho dua tshiab kom tau raws li qhov xav tau ntau dua hauv cov xwm txheej thov:
1) XLPE Uas Tiv Thaiv Tau Kub Siab (150 ℃ -200 ℃): Haum rau cov tshuab tsav hluav taws xob ua haujlwm tau zoo tiam tom ntej.
2) Cov Polyethylene Uas Muaj Pa Luam Yeeb Tsawg (LSZH): Ua raws li cov qauv ib puag ncig rau cov tsheb siv hluav taws xob tshiab.
3) Txheej Tiv Thaiv Zoo Tshaj Plaws: Txhim kho kev tiv thaiv rau kev cuam tshuam hluav taws xob (EMI) thiab txhim kho qhov sib xws hluav taws xob tag nrho (EMC) ntawm lub tsheb.
Zuag qhia tag nrho, XLPE nyob hauv txoj haujlwm tseem ceeb hauv kev lag luam cable siab rau cov tsheb fais fab tshiab vim nws qhov kev ua tau zoo heev ntawm kev rwb thaiv tsev, kev tiv thaiv hluav taws xob, lub zog kho tshuab, thiab qhov zoo ntawm tus nqi. Txawm hais tias roj hmab silicone haum rau qhov chaw kub heev, nws tus nqi siab dua ua rau nws haum rau cov kev xav tau tshwj xeeb. Rau cov cable siab hauv cov tsheb fais fab tshiab, XLPE yog qhov kev xaiv zoo tshaj plaws thiab tuaj yeem siv dav hauv cov chaw tseem ceeb xws li cov roj teeb harnesses, cov cables siab voltage, thiab cov cables them ceev.
Nyob rau hauv cov ntsiab lus ntawm kev txhim kho sai ntawm kev lag luam tsheb fais fab tshiab, cov tuam txhab yuav tsum xav txog cov yam ntxwv xws li cov xwm txheej ntawm daim ntawv thov, qhov yuav tsum tau ua kom tsis txhob kub, thiab cov peev nyiaj thaum xaiv cov ntaub ntawv cable hluav taws xob siab kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm cov cables.
