Chiitiko chinonakidza chakawana kuti mune akawanda ekutanga eorange-high-voltage connectors, anoshandiswa mumotokari kwenguva yakati, ganda repurasitiki rakaonekwa sechinhu chichena, uye chiitiko ichi hachisi chimwe chete, kwete mhuri yechiitiko, kunyanya motokari yekutengesa.
Vamwe vatengi vakandibvunza kana izvi zvichikanganisa kushandiswa kwavo. Pane ngozi here? Inokanganisa hupenyu hwebasa here?
Usati wapindura mubvunzo uyu, nyora mibvunzo mishoma kuti uwane mhinduro:
1. Sei zvakakosha kushandisa ruvara rweorenji kune yakakwira voltage connectors? Zvinoita here kusaishandisa?
2. Ndeupi rudzi rwezvinhu iyo connector kazhinji ipurasitiki shell? Ruvara rweorenji rwunobva kupi?
3. Nekuda kwekushandiswa kwezviitiko zvakakosha,? Pane dambudziko here nekushandiswa kwenguva refu?
4. Izvi zvinoita kuti tifunge nezvei uye chii chatinofanira kufunga nezvacho?
Nei high voltage connectors ichida kushandisa orenji ruvara? Hatingazvishandise here?
Kushandiswa kweorenji seruvara rwenyevero rwemagetsi akakwira kunoonekwa se "tsika yepasirese", semuenzaniso, iyo US National Electrical Code (NEC) yakagamuchira orenji seruvara rwunodiwa rwetambo dzemagetsi akakwira; kubva mukupera kwema90's apo maHEV akave akakurumbira zvishoma nezvishoma kuEVs, orenji yakashandiswa seyevhavha yeyambiro yemavara emhando yepamusoro ye xEVs, iyo inoshandiswa kuratidza waya dzemagetsi akakwira uye zvinobatanidza.high-voltage cables uye connectors; iyi ziso-inobata mavara-coding system inoratidza izvo zvakakwirira-voltage unit zvikamu hazvifanirwe kubatwa pasina kudzidziswa kwekuchengetedza kwakakodzera uye midziyo yekuzvidzivirira.
Chii chinonzi mota-giredhi yakakwira voltage? Iyo "giredhi remotokari" "high voltage concept" inowanzonzi "voltage class"B" zvinoenderana netsanangudzo yeISO 6469-3, kazhinji ine magetsi anoshanda e> 60 V uye ≤ 1500 V DC kana 30 V uye ≤ 1000 V AC. . > 30 V uye ≤ 1000 V AC, zvinoenderana neyakajairwa "High-voltage tambo dzebhazi dzisiri mudzimba dzinozivikanwa nekavha ine ruvara rwe "orange" Bhazi, mune iyi kesi, inoreva gungano, iyo inewo zvibatanidza;
Panyaya yezviyero zvekubatanidza, ingave iyo miyero mikuru yeOEM, kana Europe yakanyungudika “LV nhevedzano mwero” kana zvakafanana USCAR mwero, (LV215 216 USCAR20 SAE1742, nezvimwewo) yakataura kuti iyo yepamusoro-voltage yekubatanidza ruvara coding orenji uye nhamba yekadhi yemavara inotaura zvinodiwa zveRAL 2003, 2008 uye 2011; iyo RAL 2003 ndiyo inonyanya kupenya, RAL 2011 yakawanda yakatsvuka uye yakasviba, uye RAL 2008 iri pakati. Zvinodiwa zvinowanzotsanangurwa se RAL 2003, 2008, uye 2011; iyo RAL 2003 ndiyo yakanyanya kupenya, RAL 2011 yakanyanya kutsvuka uye yakasviba, uye RAL 2008 pakati pezviviri, nepo orenji inoda kusangana nemuvara wemakore anopfuura gumi pasina metamorphosis.
Saka ruvara rweorenji ndiwo mutemo wekutanga wemugwagwa, kana wakagadzirwa nesimbi, kazhinji unodawo kuiswa mucherechedzo munzvimbo iri pachena ye-high-voltage yambiro label, saka haigone kuve orenji? Kazhinji kwete, nekuti iyo yakakodzera mitemo yekuchengetedza inogona kurambwa.
Ndeupi rudzi rwezvinhu zvinoshandiswa pazvibatanidza nehombodo dzepurasitiki? Ruvara rweorenji rwunobva kupi?
Connector shells anowanzo gadzirwa ne polyurethane zvinhu, anowanzo shandiswa PA66 PBT, nezvimwewo, iwo akajairwa mapurasitiki mabhomba anofanirwa kuzadzisa zvinodiwa zve system insulation, uye panguva imwe chete inoda kuve nehumwe hunhu hwemuviri, senge simba rakakwana, kubvarura kuramba. , kuomarara, nezvimwewo, asi zvakare inofanirwa kuve nehunhu hwekudzoreredza moto, saka iyo CTI yakakosha ine zvakakosha zvinodiwa, kazhinji, vagadziri vachashandisa naironi zvinhu kuwedzera zvakakodzera Kazhinji, vagadziri vachashandisa naironi zvinhu zvine girazi fibre yakakodzera seyayo. zvinhu, zvakaita sePA66+30%GF_V0 kana PBT.
Rudzi rweorenji rinowanzo kuumbwa nenzira mbiri, imwe chena epurasitiki zvimedu uye imwe muzana yeruvara rwehupfu yakasanganiswa, kazhinji irwo ruvara rwetsika, rwekupedzisira ruvara rwakagadzikana, uye mutengo unoenderana wakakwirawo, vagadziri vezvinhu zvese vanofanirwa zadzisa zvinoenderana nezvinodiwa zverudzi rwetsika, senge BASF, Celanese zvichingodaro.
Nekuda kwekushandiswa kwezviitiko zvakakosha,? Pane matambudziko here nekushandiswa kwenguva refu?
Dambudziko riri pakutanga kwechinyorwa riri mubhokisi rebhatiri kunze, rakafumurwa, nzvimbo inovhenekerwa nechiedza chezuva gore rose, uye padyo nevhiri, iyo vhiri inertia yezvinosvibisa zvinosvibisa zvinokandwa kumusoro imwe muzana yakasungirirwa pane izvo zvinhu, zvichibva. pane izvi, kutanga kune zvese, mukana wekuchena wakakura nekuda kwekugara kwenguva refu kune tembiricha yakanyanya uye kupenya kwezuva, kukurumidza kukurumidza kwekuchembera kwayo, izvo zvinotungamira mukuchena, uye panguva imwecheteyo, UV nemamwe miranzi ichakonzerwa kemikari kuita uye zvinhu zvepasi, zvichikonzera kukurumidza kuchena kwezvinhu. Panguva imwecheteyo, ultraviolet rays uye mamwe miranzi inozokonzeresa kuita kwemakemikari nepamusoro pezvinhu, zvichizotungamira mukukwidziridzwa kwezvinhu uye kuchena, kuwedzera pakufumurwa uye padyo nemotokari kuchaita kuti iwedzere kusvibiswa neasidhi. -ine zvinosvibisa, izvo zvinozoita kuti kukurumidza kuparara kwemamorekuru zvinhu muasidhi pasi pekutsigirwa kwemakemikari reaction whitening.
Pakazere, kuchena kwechinyorwa kunoreva kuti kune njodzi inogona kuitika ye "embrittlement" uye "kushatiswa kwezvinhu zvemagetsi", izvo zvinokanganisa hupenyu hwayo hwesevhisi uye kuwedzera mukana wekutadza kwechigadzirwa kana uchienzaniswa neakajairwa zvibatanidza, sekupaza mushure mekukanganisa ne. zvinhu zvekunze, sematombo. Zvichienzaniswa neakajairika zvinobatanidza, kune mikana yakawanda yekukundikana kwechigadzirwa, senge kuve nyore kuputika mushure mekukanganisa kwematombo uye zvimwe zvinhu zvekunze, kuve neurombo impedance kana yakanyorova, uye kuve nyore kuparara.
Kutiita kuti tifunge nezvezvinofanira kutariswa?
Kubva pamaonero ekugadzirwa kweakakwira-voltage majoini, majoini akananga kune imwe miniaturization, kusanganisa (zvishandiso zviri nyore kubatanidza mamwe magetsi anobatika) akawedzera kureruka (yakawanda compact chimiro, diki saizi, kutetepa ukobvu, nezvimwewo) maitiro, izvi zvechigadzirwa chiri pasi. kutsvagisa tekinoroji uye kubudirira kunoisa mberi kwepamusoro zvinodiwa; semuenzaniso, mamwe abrasion-resistant contact terminals (plating zvinhu, substrate kusarudzwa, uye kumwe kutsvagisa) zvichingodaro.
