Parizvino,motokari itsva dzine simbavari kusimukira munzira yekukwira voltage uye yakakwira ikozvino.Mamwe ma-high-voltage masisitimu anogona kushingirira mavoltages akakwira se800V uye macurrents akakwira se660A.Mafungu akakura akadai uye magetsi anoburitsa magetsi emagetsi, ayo anozokanganisa kushanda kwakajairika kwezvimwe zvinhu zvemagetsi.
Kune dzimwe dzinowanzoshandiswa kudzivirira electromagnetic kupindira nzira dzepamusoro-voltage wiring harness:
(1) Kondakita ane yake yekudzivirira layer
Below is schematic diagraph yechimiro cheimwe-core high-voltage wire ine yayo inodzivirira layer, iyo inowanzo umbwa nezvikamu zviviri zvesimbi conductive material uye maviri akaturikidzana e insulating material, kubva mukati kuenda kunze ndiyo musimboti. , insulation layer, shielding layer, insulation layer.Iyo waya yepakati inowanzogadzirwa nemhangura kana aluminium, inova inotakura yezvino.Kana iyo yazvino ichipfuura nepakati waya musimboti, kupindira kwemagetsi kuchagadzirwa, uye basa rechivharo chekudzivirira ndere kudzivirira kupindira kwemagetsi, kuitira kuti kupindira kwemagetsi kunotanga kubva kune waya musimboti uye kunomira pachivharo chekudzivirira, uye kusazoburitswa. kukanganisa zvimwe zvigadzirwa zvemagetsi.
Iyo yakajairika shielding layer chimiro inogona kukamurwa kuita matatu kesi,
① Yakarukwa nhovo ine simbi foil
Kazhinji inoumbwa nezvikamu zviviri: simbi foil uye yakarukwa shielding layer.Iyo simbi foil inowanzova aruminiyamu foil, uye yakarukwa shielding layer inowanzorukwa netambo waya yemhangura, uye mwero wekuvhara i ≥85%.Iyo metal foil inonyanya kushandiswa kudzivirira kupindira kwepamusoro-frequency, uye shield yakarukwa ndeyekudzivirira kupindira kwakaderera-frequency.Kuita kwekudzivirira kwetambo ye-high-voltage ine zvikamu zviviri, kutamisa impedance uye kudzivirira attenuation, uye kudzivirirwa kweiyo tambo harness inowanzoda kusvika ≥60dB.
Iyo conductor ine shielding layer inongoda kupepeta dhizaini kana uchibvisa waya, uye wobva wadzvanya iyo terminal, zviri nyore kuona otomatiki kugadzirwa.Waya ine dhizaini yayo yekudzivirira kazhinji inotora coaxial chimiro dhizaini, kana iwe uchida kuwana iyo peeling kurapwa kwematanho maviri ekudzivirira pane mudziyo, waya pachayo inodiwa kuve neyakanyanya kunaka coaxial degree, asi izvi zvakaoma kuita. kubudirira mune chaiyo yekugadzira nzira yewaya, saka kuitira kuti irege kukuvadza tambo yetambo paunenge uchibvisa waya, zvinodikanwa kubata maviri akaturikidzana ekudzivirira zvakasiyana.Mukuwedzera, iyo shielding layer inodawo kumwe kurapwa kwakakosha.Kune waya ine shielding layer yayo, iyo wiring harness process uye yekugadzira nzira inosanganisira mamwe matanho akadai sekupepura, kucheka aluminium foil, kucheka shielding mesh, flipping mesh, uye crimping shielding mhete, sezvakaratidzwa Mufananidzo 3. Nhanho imwe neimwe inoda kuwedzera michina. uye kuiswa kwemaoko.Mukuwedzera, kana pane zvakasiiwa paunenge uchibata nhovo yekudzivirira, zvichiita kuti pave nekubatana pakati penhovo yekudzivirira uye nheyo, inokonzera matambudziko makuru ehutano.
② Single braid shield
Iyi high-voltage cable chimiro chakafanana neyakarukwa nhovo uye simbi foil chimiro chataurwa pamusoro apa, asi shield layer inoshandisa chete nhovo yakarukwa uye isina foil yesimbi, sezvakaratidzwa mumufananidzo unotevera.Sezvo simbi foil ichinyanya kushandiswa kudzivirira kukanganiswa kwepamusoro-frequency, kudzivirira kwechimiro ichi chepamusoro-frequency electromagnetic kukanganiswa kwakaipa kupfuura iyo yakarukwa nhovo uye nesimbi foil, uye mashandisirwo emhando haana kuwanda seyakarukwa nhovo nesimbi foil. kudzivirira, uye kune iyo wiring harness yekugadzira maitiro, angori mashoma matanho ekucheka aluminium foil, uye iyo yese yekugadzira maitiro haina kunyatsogadziriswa.
Kuti vagadzirise matambudziko ekugadzirisa anokonzerwa nemaitiro ekudzivirira echinyakare, dzimwe nyanzvi dziri kudzidza high-voltage cable shielding yakagadzirwa nemhangura foil ine hupamhi hwe13 ~ 17mm uye ukobvu hwe0.1 ~ 0.15mm pane imwe nzvimbo.nAngle ye30 ~ 50, uye 1.5 ~ 2.5mm inotenderera pakati peumwe neumwe.Nhoo iyi inongoshandisa simbi foil, kubvisa nhanho dzekucheka mambure, kutenderedza mambure, kudzvanya mhete yenhovo, nezvimwewo, iyo inorerutsa nzira yekugadzira waya, inoderedza mutengo wewaya, uye inochengetedza mari yemidziyo yekudzvanya nhovo. ring.
③ Single simbi foil nhoo
Nzira dziri pamusoro apa dzakati wandei ndiwo magadzirirwo echivharo chekudzivirira chewaya yakakwira voltage.Kana iwe uchifunga kubva pamaonero ekudzikisa mutengo uye optimization yekubatanidza dhizaini uye wiring harness kugadzirwa kwemaitiro, unogona kubvisa zvakananga shielding layer yewaya pachayo, asi kune iyo yose yakakwirira-voltage system, EMC inofanirwa kufunga, saka zvinodikanwa wedzera zvikamu zvine mabasa ekudzivirira mune dzimwe nzvimbo.Parizvino, mhinduro yakajairika kune yakakwirira voltage wiring harnesses ndeyekuwedzera shielding sleeve kunze kwewaya kana kuwedzera sefa kune mudziyo.
(2) Wedzera sleeve yekudzivirira kunze kwewaya;
Iyi nzira yekudzivirira inowanikwa kuburikidza newaya yekunze shielding sleeve.Chimiro cheyakakwira-voltage waya panguva ino ingori iyo insulation layer uye conductor.Ichi chimiro chewaya chinoderedza mari kune vatengesi vewaya;Kune vanogadzira waya tambo, inogona kurerutsa maitiro ekugadzira uye kuderedza kupinza kwemidziyo;Nokuda kwekugadzirwa kwe-high-voltage connectors, chimiro chese-high-voltage connector chave chiri nyore nekuda kwechido chekufunga nezvekugadzirwa kwezvindori zvekudzivirira.
Iyo 2024 Beijing Automotive Wiring Harness uye Connector Exhibition ichabatawo iyo Yemotokari wiring harness uye Connector Summit Forum panguva imwe chete, ichikoka masangano emaindasitiri nevakuru vemakambani kuti vagovane misoro inopisa senge yekumhara kushandiswa kwemotokari wiring harness mukusimudzira vakangwara. yakabatana indasitiri yemotokari uye ramangwana rekusimudzira maitiro.Kuburikidza nekutora chikamu, vanhu vanogona kukurumidza kunzwisisa mamiriro ekusimudzira uye ekucheka-kumucheto maitiro eindastiri.
Mota dzemagetsi nyowani dzinoisa pamberi zvakasiyana uye zvakatokwirira zvinodiwa zvemotokari wiring harnesses uye zvinobatanidza.Sechikamu chakakosha chezvikamu zvemotokari, mawiring harnesses uye majoini anofanirwa kushandisa yakawanda waya yekudzora tekinoroji kuti iwane yakakwira dhigirii rehungwaru kutyaira.Iyo yekudzora harness inotakura masaini edhijitari inotsiva iyo yechinyakare hydraulic kana waya yekudzora zvikamu kuti iwane nekukurumidza uye kwakaringana kutonga kwemotokari senge braking uye chidhiraivho.Sezvo sisitimu ichiwedzera kuomarara, tambo yemotokari iri panjodzi yekudhumhana, kukweshana, zvakasiyana-siyana zvinonyungudutsa uye kumwe kukukurwa kwenzvimbo yekunze uye kupfupi-dunhu uye kumwe kutadza, saka kuchengetedzwa uye kusimba kweiyo harness zvakare chimwe chezvinhu zvakakosha izvo inoda kusangana.
