Raws li cov ntaub ntawv txheeb cais ntawm kev lag luam thoob ntiaj teb txuas hauv xyoo 2021, lub tsheb sib txuas hauv lub ntiaj teb txuas kev lag luam yuav dhau kev sib txuas lus hauv kev lag luam txuas, suav txog 22.60 feem pua ntawm kev lag luam thoob ntiaj teb txuas. Cov khoom sib txuas hauv tsheb tau siv dav hauv cov tshuab hluav taws xob thiab lub cev. Tshwj xeeb tshaj yog nyob rau hauv txoj kev loj hlob ntawm kev txawj ntse thiab electrification, kom muaj nuj nqis thiab kev siv ntawmhigh-voltage connectorsntawm tag nrho lub tsheb yog nce.
1. Kev sib txuas hluav taws xob siab hauv tsheb hluav taws xob
Cov tsheb hluav taws xob xav tau ib qho ua tiav ntawm high-voltage kev twb kev txuas system, thiab ib tug ua tiav txheej ntawm high-voltage kev twb kev txuas system yuav tsum tau siv ib tug loj tus naj npawb ntawm high-voltage connectors. Tsis zoo li cov tsheb ib txwm muaj, cov xaim hluav taws xob tsawg tsom rau cov roj teeb, hluav taws xob tsav, thiab kev tswj hluav taws xob. Nyob rau hauv high-voltage system ntawm lub zog tshiab tsheb, hluav taws xob kev ua tau zoo ntawm high-voltage connectors los ntawm lub tshav kub tsis kam thiab voltage kuj ntawm connectors mus rau lub tam sim no-nqa peev xwm, EMC thiab lwm yam lub cev yam ntxwv tseem ceeb dua, qhov no yog pom tseeb txawv ntawm hluav taws xob tsheb nrog high-voltage connectors thiab tsoos tsheb nrog tsawg-voltage connectors.
High-voltage connector yeej ib txwm yog ib tug connector teb nrog high technical threshold. Thaum lub kaw lus high-voltage ua haujlwm, qhov tso tawm tam sim no mus txog ntau kaum ntawm amperes, txawm ntau pua amperes. Thaum lub high-voltage connector muaj teeb meem, nws yuav overheated, los yog kub kub los yog combustion kev huam yuaj tshwm sim. Ua cov tam sim no loj yuav tsum tau hais tias lub connector nws tus kheej muaj zoo heev tshav kub dissipation thiab shielding muaj peev xwm. Lub sijhawm ntsaws, lub peev xwm nqa tam sim no, tus nqi CTI, nplaim hluav taws xob thiab kev vibration tsis kam thiab lwm yam kev ntsuas kuj yuav tsum tau ua nruj me ntsis raws li cov qauv kom muaj kev nyab xeeb ntawm high-voltage circuit. Qhov kev sib khi dav dav ntawm cov khoom siv hluav taws xob siab yog qhov tsawg kawg nkaus IP67, thiab qee zaum IP6K9K tseem xav tau rau cov xwm txheej tshwj xeeb. Nyob rau hauv cov nqe lus ntawm tus nqi thiab kev xav tau, nws yuav ntau dua li peb cov khoom sib txuas.
Lwm yam ntxwv ntawm high-voltage connector yog high-voltage interlock. Txhua qhov kev txhim kho ntawm high-voltage connector yog ua los ntawm high-voltage interlock muaj nuj nqi. Lub thiaj li hu ua high voltage interlocking txhais tau hais tias lub high voltage Circuit Court yog tswj los ntawm cov teeb liab voltage tsawg. Los ntawm cov txheej txheem kev sib txuas ntawm high voltage interlocking, lub connector system nrog high voltage interlocking yuav raug txiav tawm thaum nws yog electrified. Lub hwj chim davhlau ya nyob twg thiab lub interlocking davhlau ya nyob twg yuav tsum tau txuas / disconnected successively kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm lub high voltage kev twb kev txuas system. Los ntawm kev ua kom lub cev muaj zog sib cuam tshuam zoo tib yam mus rau high-voltage interlock ntxiv rau electromagnetic shielding, mus rau qhov sib ntxiv ntawm qhov kev xauv xauv thib ob, qhov kev cuam tshuam ntawm high-voltage yog lub luag haujlwm tseem ceeb nyob ib ncig ntawm txhua qhov kev txhim kho ntawm high-voltage connector. hluav taws xob tsheb.
2. Kev lag luam nplai ntawm high-voltage connectors rau hluav taws xob tsheb
Lub ntiaj teb connector kev lag luam loj nyob rau hauv 2021 yuav yog hais txog 77.99 billion US dollars, nrog rau ib lub xyoo nce ntawm 24.3 feem pua. Ntawm lawv, qhov loj ntawm Tuam Tshoj txoj kev lag luam txuas yog US $ 24.978 billion, nce 23.8 feem pua ntawm xyoo. Lub ntiaj teb pib txuas kev lag luam loj yog kwv yees li 17.626 billion US las, suav txog 22.6 feem pua.
Subdivided rau hauv high-voltage connectors, nws yog kwv yees hais tias lub lag luam loj ntawm Tuam Tshoj lub domestic tsheb high-voltage connectors yuav yog hais txog 2.9 billion yuan los ntawm 2020. Nws yog kwv yees hais tias nyob rau hauv 2025, lub lag luam loj ntawm domestic automotive high-voltage connectors yuav nce. los ntawm 63 feem pua CAGR rau 33.4 billion yuan. Raws li kev lag luam kwv yees, los ntawm qhov kawg ntawm 2022, kev ua lag luam loj ntawm cov khoom siv hluav taws xob hluav taws xob hauv tsev yuav yog li 11.5 billion yuan.
Lub concentration ntawm tag nrho cov connector kev lag luam yog siab. Cov tsoos thoob ntiaj teb connector manufacturers muaj technical thiab ua lag luam zoo, uas yog tib yam nyob rau hauv lub teb ntawm high-voltage connectors. Nyob rau hauv xyoo tas los no, ib tug loj tus naj npawb ntawm zoo heev Suav high-voltage connector manufacturers tau tshwm sim nyob rau hauv lub lag luam tsheb lag luam. Lawv tau nkag mus rau hauv kev sib txuas ntawm high-voltage connectors los ntawm cov tsheb ua lag luam, cov khoom tsim thiab cov thev naus laus zis, thiab tsim cov txiaj ntsig zoo ua ntej nthuav dav cov neeg caij tsheb lag luam.
