Ib qho tshwm sim nthuav pom tau hais tias nyob rau hauv ntau yam ntawm cov thawj txiv kab ntxwv high-voltage connectors, siv nyob rau hauv lub tsheb rau tej lub sij hawm, lub plhaub yas tshwm dawb tshwm sim, thiab qhov tshwm sim no tsis yog ib qho kev zam, tsis yog tsev neeg ntawm qhov tshwm sim, lub tsheb lag luam tshwj xeeb.
Qee cov neeg siv khoom nug kuv seb qhov no puas cuam tshuam rau lawv txoj kev siv. Puas muaj kev pheej hmoo? Nws puas cuam tshuam rau lub neej kev pabcuam?
Ua ntej teb lo lus nug no, sau ob peb nqe lus nug kom pom cov lus teb:
1. Vim li cas thiaj yuav tsum siv cov xim txiv kab ntxwv rau cov khoom siv hluav taws xob siab? Nws puas tuaj yeem siv tsis tau?
2. Cov khoom siv dab tsi yog qhov txuas feem ntau yog lub plhaub yas? Cov xim txiv kab ntxwv tuaj qhov twg?
3. Vim yog siv cov xwm txheej tshwj xeeb,? Puas muaj teeb meem nrog kev thov mus sij hawm ntev?
4. Qhov no ua rau peb xav txog dab tsi thiab peb yuav tsum xyuam xim rau dab tsi?
Vim li cas cov hluav taws xob txuas hluav taws xob siab yuav tsum siv cov xim txiv kab ntxwv? Peb puas tuaj yeem siv tsis tau?
Kev siv cov txiv kab ntxwv ua cov xim ceeb toom rau cov hluav taws xob siab yog suav tias yog "kev coj ua thoob ntiaj teb", piv txwv li, US National Electrical Code (NEC) tau txais cov txiv kab ntxwv raws li cov xim uas yuav tsum tau muaj rau cov cables siab; Txij li thaum lig 90′s thaum HEVs tau maj mam nrov rau EVs, txiv kab ntxwv tau siv los ua lub zog hluav taws xob ceeb toom xim rau xEVs, uas yog siv los qhia cov xov hlau hluav taws xob thiab cov khoom sib txuas.high-voltage cables thiab connectors; qhov muag-catching xim-coding system txheeb xyuas cov khoom siv high-voltage unit yuav tsum tsis txhob kov yam tsis muaj kev cob qhia kev nyab xeeb thiab cov khoom siv tiv thaiv tus kheej.
Automotive-qib high voltage yog dab tsi? Cov "automotive qib" "high voltage concept" feem ntau yog "voltage class "B" raws li lub ntsiab lus ntawm ISO 6469-3, feem ntau nrog kev khiav hauj lwm voltage ntawm> 60 V thiab ≤ 1500 V DC los yog 30 V thiab ≤ 1000 V AC . > 30 V thiab ≤ 1000 V AC, raws li tus qauv "High-voltage bus cables uas tsis nyob rau hauv lub tsev yuav tsum raug txheeb xyuas los ntawm ib tug cover nrog cov xim "txiv kab ntxwv" lub tsheb npav, nyob rau hauv cov ntaub ntawv no, hais txog lub rooj sib txoos, uas kuj muaj cov connectors;
Nyob rau hauv cov nqe lus ntawm connector qauv, seb nws yog cov loj OEM cov qauv, los yog cov teb chaws Europe tau yaj "LV series qauv" los yog zoo xws li USCAR cov qauv, (LV215 216 USCAR20 SAE1742, thiab lwm yam.) tau teev tias cov high-voltage connector xim coding txiv kab ntxwv thiab daim npav xim tus lej teev cov cai ntawm RAL 2003, 2008 thiab 2011; ntawm uas RAL 2003 yog qhov ci tshaj, RAL 2011 yog xim liab thiab tsaus dua, thiab RAL 2008 yog nyob nruab nrab. Cov kev xav tau feem ntau txhais tau tias yog RAL 2003, 2008, thiab 2011; ntawm uas RAL 2003 yog qhov ci tshaj plaws, RAL 2011 yog xim liab thiab tsaus dua, thiab RAL 2008 ntawm ob, thaum txiv kab ntxwv yuav tsum tau ua kom tau raws li cov xim ntawm ntau tshaj 10 xyoo tsis muaj metamorphosis.
Yog li cov xim ntawm txiv kab ntxwv yog txoj cai yooj yim ntawm txoj kev, yog tias nws yog ua los ntawm cov hlau, feem ntau kuj yuav tsum tau muab cim rau hauv qhov pom tseeb ntawm daim ntawv ceeb toom high-voltage, yog li tsis tuaj yeem ua txiv kab ntxwv? Feem ntau tsis yog, vim hais tias cov cai tswj kev nyab xeeb cuam tshuam yuav raug tsis lees paub.
Cov ntaub ntawv dab tsi yog siv rau kev sib txuas nrog cov plhaub yas? Cov xim txiv kab ntxwv tuaj qhov twg?
Cov plhaub txuas feem ntau yog ua los ntawm cov ntaub ntawv polyurethane, feem ntau siv PA66 PBT, thiab lwm yam, cov plhaub yas dav dav yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua ntawm cov txheej txheem rwb thaiv tsev, thiab tib lub sijhawm yuav tsum muaj qee yam ntawm lub cev, xws li lub zog txaus, tsim kua muag. , toughness, thiab lwm yam, tab sis kuj yuav tsum muaj cov yam ntxwv ntawm cov nplaim retardant, yog li qhov dav dav CTI tus nqi muaj cov kev cai tshwj xeeb, feem ntau, cov tuam ntxhab yuav siv cov ntaub ntawv nylon kom tsim nyog, feem ntau, manufacturers yuav siv cov khoom nylon nrog cov iav fiber ntau raws li nws cov khoom siv, xws li PA66 + 30% GF_V0 lossis PBT.
Cov xim txiv kab ntxwv feem ntau yog tsim nyob rau hauv 2 txoj kev, ib qho yog dawb yas hais ntxiv rau qee feem pua ntawm cov xim hmoov sib xyaw, feem ntau yog xim xim, cov xim tom kawg yog ruaj khov dua, thiab cov nqi sib xws kuj siab dua, cov khoom lag luam dav dav yuav tsum ua tau raws li cov qauv kev cai ntawm cov xim kev cai, xws li BASF, Celanese thiab lwm yam.
Vim yog siv cov xwm txheej tshwj xeeb,? Puas muaj teeb meem nrog daim ntawv thov mus sij hawm ntev?
Qhov teeb meem thaum pib ntawm tsab xov xwm yog nyob rau hauv lub roj teeb lub thawv sab nraud, raug, qhov chaw raug tshav ntuj txhua xyoo puag ncig, thiab nyob ze rau lub log, lub log inertia ntawm corrosive pollutants pov tseg ib feem ntawm cov khoom, raws li ntawm qhov no, ua ntej ntawm tag nrho cov, qhov tshwm sim ntawm whitening yog ntau dua vim hais tias ntawm nws lub sij hawm raug rau kub kub thiab tshav ntuj, accelerating tus ceev ntawm nws aging, uas ua rau kom whitening, thiab nyob rau tib lub sij hawm, UV thiab lwm yam rays yuav tshwm sim. tshuaj lom neeg cov tshuaj tiv thaiv thiab cov khoom nto, uas ua rau kom ceev cov ntaub ntawv whitening. Nyob rau tib lub sijhawm, cov kab hluav taws xob ultraviolet thiab lwm cov kab hluav taws xob kuj tseem yuav ua rau muaj tshuaj lom neeg nrog cov khoom siv saum npoo, yog li ua rau cov ntaub ntawv nrawm nrawm thiab ua kom dawb huv, ntxiv rau kev nthuav tawm thiab nyob ze rau lub tsheb yuav ua rau nws muaj peev xwm corroded los ntawm cov kua qaub. -muaj kuab paug, uas yuav ua rau kom ceev decomposition ntawm cov khoom molecules nyob rau hauv cov kua qaub nyob rau hauv kev txhawb nqa ntawm cov tshuaj tiv thaiv dawb.
Zuag qhia tag nrho, whitening ntawm cov khoom txhais tau hais tias muaj kev pheej hmoo ntawm "embrittlement" thiab "degradation ntawm cov khoom hluav taws xob", uas yuav cuam tshuam rau nws txoj kev pab cuam lub neej thiab ua rau muaj kev pheej hmoo ntawm cov khoom tsis ua haujlwm piv rau cov khoom sib txuas, xws li tawg tom qab cuam tshuam nrog. cov khoom txawv teb chaws, xws li pob zeb. Piv nrog rau cov khoom sib txuas ib txwm muaj, muaj feem ntau ntawm cov khoom lag luam tsis ua haujlwm, xws li ua rau muaj kev cuam tshuam ntau dua tom qab kev cuam tshuam ntawm pob zeb thiab lwm yam khoom txawv teb chaws, muaj impedance tsis zoo thaum ntub dej, thiab ua rau muaj kev cuam tshuam ntau dua.
Yuav ua rau peb xav txog dab tsi yuav tsum tau them nyiaj mloog?
Los ntawm qhov kev xav ntawm txoj kev loj hlob ntawm high-voltage connectors, connectors mus rau ntau miniaturization, kev koom ua ke (cov ntaub ntawv yooj yim dua rau suav nrog ntau hluav taws xob tiv tauj) ntau lub teeb (ntau dua compact qauv, me me, thinner thickness, thiab lwm yam) qauv, qhov no rau cov khoom hauv qab. kev tshawb fawb thev naus laus zis thiab kev ua tiav tau muab cov kev xav tau siab dua; Piv txwv li, ntau dua abrasion-resistant contact terminals (plating cov ntaub ntawv, xaiv substrate, thiab lwm yam kev tshawb fawb) thiab hais txog.
Nyob rau tib lub sijhawm, cov ntaub ntawv yas kuj muab cov kev xav tau siab dua, qhov chaw ua haujlwm dav dav thoob plaws hauv lub neej kev xav tau, siab dua CTI cov cai, thiab 0.4mmV0 raws li cov kev cai ntawm cov khoom siv hluav taws xob, tag nrho lub neej voj voog ntawm kev ruaj ntseg ntawm cov xim, cov ntaub ntawv. , siab kub tsis kam, siab thermal conductivity ntawm cov khoom, yuav tsum tau tsom rau cov khoom additives ntawm cov hluav taws xob corrosion ntawm cov neeg sib cuag, lub cev stability ntawm cov khoom nyob rau hauv lub sij hawm ntev kev siv ntawm lub zog qauv stability ntawm cov ntaub ntawv thov nyob rau hauv hnyav ib puag ncig, thiab lwm yam ...
