1. 1. Ubume bocingo lombane
Iingcingo ngabathwali bokuhambisa imiqondiso yombane kunye nemisinga. Ubukhulu becala zenziwe nge-insulation kunye neengcingo. Iingcingo zeenkcukacha ezahlukeneyo zihambelana nezixhobo ezahlukeneyo zokugquma kunye nezakhiwo zocingo zethusi. Iiparamitha zokuvavanya zocingo ziquka ubukhulu becala locingo lobhedu, inani, ubukhulu be-insulation kunye nedayamitha yangaphandle yecandelo lomqhubi. Ukuze kuncitshiswe izinga lokuphazamiseka kwemiqondiso eyahlukeneyo ngexesha lothumelo, iingcingo eziphothiweyo kunye neengcingo ezikhuselweyo nazo zisetyenziswa kwiimoto. Ngenxa yobuninzi beengcingo ezisetyenziswa kwisithuthi, ukwenzela ukuba kube lula ukuveliswa kweentambo zokubopha kunye nokugcinwa kokuthengiswa emva kokuthengiswa kwesithuthi sonke, imibala eyahlukeneyo ibekwe ngokubanzi kwi-insulation skin ukubahlula.
1. 2. Iinkcukacha zeengcingo
Iingcingo ezisetyenziswa ezimotweni ubukhulu becala ziingcingo ezine-voltage ephantsi. Ngophuhliso lwezithuthi zombane ezixutyiweyo kunye nezithuthi zombane ezisulungekileyo, ngakumbi nangakumbi iintambo zombane ezinombane ophezulu zisetyenziswa kwiimoto. Nangona kunjalo, umbhali weli nqaku uxubusha kakhulu ngeengcingo eziphantsi kwe-voltage, kunye neshishini langoku eliqhelekileyo Iinkcazo zengcingo ziingcingo eziqhelekileyo zaseJapan kunye neengcingo eziqhelekileyo zaseJamani.
2. Uyilo kunye nokukhethwa kweengcingo zemoto
2. 1. I-ampacity yocingo
I-ampacity yeingcingo yinto ekufuneka iqwalaselwe kwinkqubo yoyilo, kwaye umthwalo wexabiso langoku leengcingo lichazwe kwi-GB 4706. 1-2005. Umthamo wangoku wokuthwala ucingo unxulumene necandelo lomnqamlezo wocingo, kwaye linxulumene nezinto eziphathekayo, uhlobo, indlela yokusonga kunye nobushushu be-ambient yocingo. Kukho izinto ezininzi ezinempembelelo kwaye ukubala kunzima kakhulu. I-ampacity yeengcingo ezahlukeneyo zidla ngokufumaneka kwi-manual.
Izinto ezichaphazela i-ampacity zingahlulwa zibe yimiba yangaphakathi kunye nezinto zangaphandle. Iipropati zocingo ngokwazo zizinto zangaphakathi ezichaphazela amandla akhoyo okuphatha ucingo. Ukwandisa indawo engundoqo, usebenzisa izinto eziphezulu ze-conductivity, usebenzisa izinto zokugquma ezinokumelana nokushisa okuphezulu kunye nokufudumala kwe-thermal conductivity, kunye nokunciphisa ukuxhathisa ukudibanisa kunokunyusa ukuthwala kwangoku umthamo wocingo. Izinto zangaphandle zinokwandisa i-ampacity ngokunyusa i-gap yokubeka ucingo kunye nokukhetha indawo yokwakheka kunye nobushushu obufanelekileyo.
2. 2. Ukuhambelana kweengcingo, izihlanganisi kunye neetheminali
Ukutshatiswa kweengcingo kunye neetheminali zokudibanisa zihlulwe ikakhulu ngokuhambelana nomthamo wangoku wokuthwala kunye nokuhambelana nokwakhiwa komatshini wokukrazula.
2. 2. 1. Ukuthelekisa umthamo wangoku wokuthwala iitheminali kunye neengcingo
Umthamo wokuthwala wangoku weetheminali kunye neengcingo kufuneka zihambelane ukuqinisekisa ukuba zombini iitheminali kunye neengcingo zinokuhlangabezana neemfuno zomthwalo ngexesha lokusetyenziswa. Kwezinye iimeko, ixabiso langoku elivumelekileyo le-terminal liyaneliswa, kodwa ixabiso langoku elivumelekileyo locingo ligqithisiwe, ngoko kufuneka kuhlawulwe ingqalelo ekhethekileyo. Umthamo wangoku wokuthwala iingcingo kunye neetheminali unokufunyanwa ngokujonga iitafile kunye nolwazi olunxulumeneyo.
Ixabiso langoku elivumelekileyo locingo: i-terminal material lubhedu, ixabiso langoku xa i-terminal yeqondo lokushisa liyi-120 ℃ (iqondo lokushisa elichasene nobushushu be-terminal) xa linamandla; i-alloy yobhedu ekwazi ukumelana nobushushu, ixabiso langoku xa ubushushu besiphelo buyi-140 ℃ (iqondo lobushushu elimelana nobushushu letheminali) ixabiso.
2. 2. 2. Ukuthelekisa i-terminal kunye ne-wire ampacity mechanical crimping inxalenye
Ukuze kuqinisekiswe ukuhambelana kwesakhiwo se-crimping yomatshini, oko kukuthi, ii-terminals kufuneka zihlangabezane nemigangatho ethile emva kokuqhawula iingcingo. Izinto ezinempembelelo ikakhulu ziquka ezi ndawo zilandelayo:
(1) Xa iingcingo zivulwa, kuyimfuneko ukuqinisekisa ukuba i-insulation kunye ne-core of the wire harness ayichanekanga kwaye ayibonakali. Isakhiwo esiqhelekileyo emva kokuvulwa siboniswe kuMzobo.
