Muzviitiko zvine simba guru remagetsi zvakaita sesimba idzva, hunyanzvi hwemagetsi uye kutonga kwemaindasitiri, kukwesha magetsi ndiyo nzira huru yekuona kuti magetsi akabatana zvakanaka. Nhamba dzinoratidza kuti 35% yemoto wemagetsi inokonzerwa nekubatana kusina kusimba kana kusina kunaka kwemagetsi. Senzira huru yekubatanidza magetsi, chiyero chekukwesha magetsi chinotarisa zvakananga simba remagetsi uye kufambisa magetsi kwemagetsi. Chinyorwa chino chinotsanangura huwandu hwehuwandu hwemagetsi anoshandiswa, fomura yekuverenga, zvinhu zvinopesvedzera uye zvinodiwa pakushanda kwemagetsi anoshandiswa pakugadzira magetsi akasimba, izvo zvinogona kushandiswa nekukasika.
I. Chii chinonzi Compression Ratio? Tanga wanzwisisa tsananguro yayo huru
Chiyero chekudzvanya (chinozivikanwawo sechiyero chekudzvanya kana chiyero chekudzvanya) chinoyera chiyero chekuchinja kwenzvimbo yemuchina usati wapwanya uye mushure mekupwanya, zvichiratidza kusimba kwekubatana pakati pemuchina nematerminal. Kune nzira mbiri dzekuverenga dzakakurumbira muindasitiri iyi.
USCAR-21 (Inowanzoshandiswa mumotokari uye munzvimbo dzemagetsi, mwero wekumanikidzwa)
Chiyero chekudzvanya (%) = 100×(1 - Nzvimbo yemudhudhudhu mushure mekupwanya / Nzvimbo yemudhudhudhu wezita usati wapwanya)
Muenzaniso: Kondakita ye50mm² isati yavharwa ine nzvimbo yayo yekuyambuka ne20% mushure mekuvharwa, ine chiyero chekudzvanywa kwe20%.
VW 60330 (Inoshandiswa zvakanyanya muzviyero zveGerman uye muminda yemaindasitiri, chiyero chekusimbaradza)
Chiyero chekudzvanya (%) = Nzvimbo yemudhudhudhu mushure mekukwenya / Nzvimbo yemudhudhudhu wezita rekuti danda remukati usati wakwenya × 100%
Muenzaniso: Kana nzvimbo yemuchina wekufambisa mushure mekupwanya simbi iine 80% yenzvimbo yekutanga, chiyero chekudzvanywa kwesimbi i80%.
II. Range Yakakodzera Yekudzvanywa Kwenzvimbo Yepamusoro Yekupwanya Chiteshi
Zvinodiwa zvikuru pakushandisa simba remagetsi (conductors dzemhangura, 6–400mm²): simba rekudzivirira kubata, simba rekubvisa simba, simba rekudzivirira kupisa uye simba rekudzivirira kudedera. Mhando dzakakodzera dzinosiyana zvichienderana nezvinhu uye mamiriro ekushanda.
1. Madhaivha emhangura (anonyanya kushandiswa mumaindasitiri matsva esimba, simba uye ekudzora maindasitiri)
Rudzi rwakakodzera rwese: 15%–25% (chiyero chekudzvanywa) / 75%–85% (chiyero chekudzvanywa)
Mamiriro ezvinhu akakamurwa:
Simba remagetsi rakajairika (6–95mm²): 18%–22% yekumanikidzwa, kuenzana kwekudzivirira uye simba.
Simba guru kwazvo (120–400mm²): Chiyero chekudzvanya 22%–25%. Kumanikidzwa kwakanyanya kunodiwa kuti pave nekupwanya oxide layers.
Kudengenyeka kwemhepo kwakanyanya (motokari itsva dzine simba / marobhoti): 15%–20% yekumanikidzwa, inodzivirira tambo yewaya kutyoka kubva mukumanikidzwa kwakanyanya.
2. Kondakita yearuminiyamu (tambo yemagetsi / bhazi)
Aruminiyamu inogona kuoxidation uye haina ductility yakanaka. Chiyero chepamusoro chekumanikidzwa chinodiwa kuti ganda reoxide riputse: 30%–50% compression ratio, 50%–70% compaction ratio
3. Mareferensi eMaitiro eIndasitiri
National Standard GB/T 14315-2008: Chiyero chekudzvanya kwetambo yemagetsi 20%-30%
IEC 60352-2: Chiyero chekumanikidzwa kwe crimping isina solder 15%–25%
USCAR-21 (Motokari Yakajairwa): Chiyero chekudzvanywa kwesimba 15%–20%, chiyero chekusavapo＜10%
III. Migumisiro yeCompression Ratio Yakanyanya Kukwirira kana Yakaderera
✅ Chiyero chekudzvanywa kwakaderera (<15%)
Kubatana kwakasununguka pakati pemuchina wemagetsi nechombo, kukwira kwakanyanya kwekudzivirira kubata. Kupisa kwakanyanya pasi pesimba remagetsi rakawanda nekupisa kunopfuura 50℃.
Simba rekudhonza harina kukwana, riri pasi pe80% yemutengo wakajairika, rinogona kusunungura nekudonha kana richidedera.
Maburi makuru anobvumira hunyoro neguruva kupinda, zvichiita kuti oxidation uye ngura zvikurumidze.
✅ Kumanikidzwa kwakanyanya (>30%)
Kuchinja-chinja kwakanyanya kana kutotyoka kwetambo dzewaya dzemhangura, kuderedza kugona kwekutakura magetsi.
Kutsemuka kwemadziro ekupedzisira uye kuchinja kwesimba remuchina zvichikonzera kurasikirwa nesimba remuchina.
Kuwanda kwezvinonetsa munharaunda kunokonzera kutsemuka kana kupisa kwacho kwawedzera uye kwadzikira kwenguva refu.
IV. Zvinhu Zvitatu Zvakakosha Pakusarudza Chiyero Chakakodzera Chekudzvanywa
1. Zvinhu zvemutyairi
Mhangura: Ductility yakanaka, chiyero chekudzvanya 15%-25%
Aruminiyamu: Rutivi rwakaoma rwe oxide, chiyero chekudzvanywa kwe 30% -50%
Aruminiyamu yakaputirwa nemhangura: Yepakati nepakati, chiyero chekumanikidzwa 20%-30%
2. Rudzi rwechiteshi
Chiteshi chechubhu (OT/UT): 18%–22% compression ratio, hexagonal die inonyanya kufarirwa
Chiteshi chakavhurika (SC): 20%–25% compression ratio, mupendero wakavhurika wakaoma unodiwa
Chiteshi chitsva chemagetsi ane simba guru (LV): 15%–20% compression ratio, dhizaini yekudzivirira tambo kupwanyika
3. Zvishandiso zvekupwanya uye madhiri
Pliers dze hydraulic crimping (16–24t): Dzakakodzera 6–400mm², chiyero chekudzvanywa chakasimba che20%–25%
Hexagonal die: Kushushikana kwakafanana, kukanganisa kwekumanikidza＜± 2%, sarudzo inosarudzwa
Dheya rakatenderera: Kushandiswa kuri nyore chete, kukanganisa kukuru ±5%, hazvikurudzirwi kune magetsi akakura zvakanyanya
V. Kushanda Kunoshanda: Kudzora Kuyera Kwekumanikidzwa & Kuongorora Hunhu
1. Maitiro Ekugadzirisa Nekunyatsojeka
Kufananidza Specification: Match terminals, madhiri uye cable cross-section one-to-one
Kurapa kwekubvisa: Kureba kwekubvisa kwakaenzana nekudzika kweferrule pamwe ne1-2mm, chengeta tambo dzacho dzisina oxidation kana burrs.
Kuisa girisi rinofambisa mhepo: Isa girisi rakagadzirwa pamagetsi emhangura uye grisi chaiyo pamagetsi ealuminium kubvisa firimu reoxide
Kushanda kwe crimping: Isa conductor zvizere, dzvanya kusvika pamutengo wakatarwa, bata kumanikidzwa kwemasekondi 3-5, crimp nzvimbo 2-3
Kusimbiswa kwekumanikidzwa: Yera dhayamita yekunze mushure mekukombama, chikanganiso chechiyero chekutonga mukati me ± 2%
2. Zvinodiwa zveKuongorora Hunhu
Chitarisiko: Hapana mitswe, mapundu kana mafambiro akazaruka, kuvharika kwakafanana
Saizi: Kutsauka kwedhayamita yekunze ≤±5%, chiyero chekumanikidzwa mukati mechikamu chakatarwa
Zvemagetsi: Kudzivirira kubata ≤1.1 kakapetwa kupfuura kondakita wehurefu hwakaenzana, kukwira kwetembiricha ≤30℃ mushure mekuyedzwa kweawa imwe chete kwemagetsi ane simba rakawanda
Michina: Simba rekudhonza rinosvika padanho rakajairwa (kondakita ane tambo ≥80N), hapana kusunda kana tambo dzakatyoka
VI. Pfupiso: Nhamba Dzakakosha dzeKupwanya Kwemagetsi Akawanda
Kondakita wemhangura (6–400mm²): Chiyero chekudzvanya chakakodzera 18%–22%, chiyero chekudzvanya 78%–82%
Kondakita wearuminiyamu: Chiyero chekudzvanya 30%–50%
Nheyo huru: Dzivisai kupwanya machira asina kukwana kana akawandisa. Match dies, kutonga kwakarurama uye kuongorora kwakasimba kubvisa njodzi dzekubatana kwakasununguka.
Chinobatanidza magetsi cheAMASS chinoshandisa terminal iyo inogona kukubatsira kuchengetedza kubatana kwakasimba mumamiriro ezvinhu ekushandisa akadai sekuzunguzika kwakasimba, kudzokororwa kwekupisa kwakakwira nekwakaderera, vhoriyamu diki, uye simba rakawanda.
