Indlela yokukhetha ubungakanani obufanelekileyo be-SC Cable Lug kwiintambo ezisetyenziswa kakhulu

Ubhedu lwe-SC olugqunywe ngetin Iintambo zeCable ngobukhulu obupheleleyo, zilungele uqhagamshelo lwebhetri enamandla aphezulu kunye nokusasazwa kwamandla.

Khetha intambo engalunganga kwaye iimpawu zibonakala ngokukhawuleza: uqhagamshelo olushushu, ibholiti engahlaliyo, okanye i-crimp ekhululekayo emva kweenyanga ezimbalwa zokungcangcazela. Kuye nabani na ofaka iibhetri, ii-inverters, iiswitchgear, okanye iisekethe zeemoto, ukufumana ubungakanani be-SC lug ngokuchanekileyo okokuqala kusindisa ukuthunyelwa okuninzi kunye neentloko zewaranti. Nantsi indlela abathengi kunye nabafaki abathatha ngayo eso sigqibo.

Ithetha ukuthini ireyithingi ethi "SC" kwi-copper lug?

Intambo ye-SC lug yi-terminal ye-tubular copper enolwimi oluyindandatho, ebotshelelwe kwintambo ebotshelelweyo ukuze yenze uqhagamshelo lwe-bolt-down. Igama lilandela ingqiqo elula: inombolo emva kwe-"SC" yi-conductor cross-section kwiimilimitha zesikwere, kwaye inombolo emva kwe-dash yi-stud hole diameter kwiimilimitha. I-SC25-8 lug, umzekelo, ingena kwi-25 mm2 conductor kunye ne-M8 bolt. Nje ukuba ufunde ikhowudi ngale ndlela, uninzi lwemisebenzi yokuqikelela iyanyamalala.

Amanani amabini abalulekile ngezizathu ezahlukeneyo. Ubungakanani bomqhubi bulawula indlela ibhereli ebamba ngayo ucingo kunye nokuba ingakanani i-current enokuyithwala ngaphandle kokufudumeza. Umngxuma we-stud kufuneka ulingane ne-bolt ekwi-busbar yakho, i-breaker, okanye isiphelo sebhetriKuqhelekile ukuba abathengi babethelele ubungakanani bentambo baze bafumanise ukuba iringi ayifanelani ne-stud ye-M10, ngoko ke soloko uqinisekisa amanani omabini phambi kokuba u-odole.

Ukulinganisa ubungakanani belugi negeyiji yocingo

Ibhereli kufuneka ihambelane nomqhubi ogoba kuyo. Ukuba ibhereli inkulu kakhulu, ibhereli ayinakuyicinezela imicu ngokuqinileyo, ishiye ijoyinti enokumelana okuphezulu eshushu phantsi komthwalo. Incinci kakhulu, kwaye awukwazi ukufaka umqhubi opheleleyo, ngoko imicu iyanqunyulwa okanye igoqwe kwaye i-ampacity elinganisiweyo iyehla.

Sebenzisa icandelo eliprintiweyo kwijakethi yekhebula njenge-ankile yakho. I-conductor ye-16 mm2 (malunga ne-6 AWG) idibene ne-SC16 lug; intambo ye-50 mm2 (malunga ne-1/0 AWG) ifuna i-SC50. Xa intambo yakho ichazwe kwi-AWG kuphela, yiguqulele kwi-mm2 ngaphambi kokukhetha, kuba ii-SC lugs zakhiwe kwiibhareli ze-metric. Isalathiso esifutshane: I-10 AWG imalunga ne-6 mm2, i-4 AWG imalunga ne-25 mm2, kunye ne-2/0 AWG imalunga ne-70 mm2. Ukuba intambo iphakathi kobukhulu obubini, khetha i-lug ehambelana ne-conductor yokwenyani elinganisiweyo endaweni yokuyisondeza.

Indlela umthwalo wangoku ochaphazela ngayo ukhetho lwakho

I-lug ayinayo i-amp rating enye yodwa; amandla ayo okwenyani axhomekeke kwi-conductor, umgangatho we-crimp, kunye nobushushu bokusebenza obuyijikelezileyo. Oko kuthethiweyo, ubungakanani bebharele oyikhethayo kwi-wire buhlala buphethe umbane ofanayo nowe-wire olinganiswe ngawo, ukuba i-crimp yenziwe ngokuchanekileyo. Iingxaki ziyavela xa abafaki besebenzisa i-lug encinci "ukuze nje bayifake kwi-bolt." Kwi-100 A nangaphezulu, nokwanda okuncinci kokumelana nokuqhagamshelana kujika kube bubushushu obulinganiswayo, kwaye ubushushu bukhawulezisa i-oxidation, ephakamisa ukumelana ngakumbi. Yi-loop ephela kwi-joint engasebenziyo.

Kwimisebenzi eqhubekayo yamandla aphezulu njengeebhokisi zokudibanisa amandla elanga, iikhabhathi zokutshaja ze-EV, okanye izitishi ze-transformer, iinkcukacha ezimbini ziyaphumelela. Okokuqala, khetha ii-lugs ze-copper ezifakwe kwi-tin endaweni ye-copper engenanto; umaleko we-tin uyamelana nokugqwala kwaye ugcine ukumelana nokudibana kuzinzile kwiminyaka emininzi yenkonzo. Okwesibini, qinisekisa ubukhulu bodonga lwe-copper. Ii-lugs ezibhityileyo, ezigxinyiweyo ziyaguquguquka ngokungalinganiyo phantsi kwe-crimp efanelekileyo, ngelixa ii-lugs zetyhubhu ezenziweyo okanye ezingenamthungo zibamba imo yazo kwaye zigcina ukumelana kuphantsi.

Uluhlu lokuhlola ukhetho olusebenzayo

Ngaphambi kokuba ufake iodolo, hamba ngala manqaku:

• Qinisekisa icandelo elinqamlezileyo lomqhubi kwi-mm2, uguqule ukusuka kwi-AWG ukuba kuyimfuneko.
• Qinisekisa ububanzi be-stud okanye i-bolt kwisixhobo esiza kusetyenziswa zii-lug bolts.
• Khetha ukuba zeziphi ezingenanto okanye ezifakwe i-tin ngokusekelwe kwindalo esingqongileyo; iindawo zangaphandle, zaselwandle, nezifumileyo mazibe zezifakwe i-tin.
• Jonga ubude bebharele ukuze isixhobo sokugoba sikwazi ukufaka i-crimp enye okanye ezimbini ngokupheleleyo.
• Qinisekisa ukuba i-lug iyahlangabezana nomgangatho ofunwa ngumthengi wakho, njenge-RoHS yezinto zomqhubi.

I-odolo emfutshane yesampulu ixabisa ixabiso elincinci. Faka intambo enye kwintambo yakho yokwenyani, uze wenze uvavanyo olulula lokutsala kunye nokujonga ngokukhawuleza ukumelana. Ukuba ijoyinti iyabamba kwaye ihlala ipholile xa ithwalwa, unobungakanani obufanelekileyo.

Kutheni umgangatho we-crimp ubaluleke njengobungakanani

Nokuba ilug enkulu ngokwaneleyo iyasilela ukuba ikrwitshiwe ngedayi engalunganga okanye isixhobo esigugileyo. I-crimp kufuneka icinezele ibhere ibe yintambo eqinileyo, eqinileyo nengenagesi kunye neentambo, kungabikho zikhewu zibonakalayo kwaye kungabikho zintambo ziphumayo. I-hex okanye i-indent crimp evela kwisixhobo se-hydraulic iqhelekile kwii-SC lugs ezingaphezulu kwe-16 mm2. Ubukhulu obuncinci bunokwenziwa nge-ratchet crimper esemgangathweni. Emva kokukrwitshiwe, ibhere kufuneka ibonise ukuguquguquka okucocekileyo, okulinganayo, kwaye ucingo alufanele lujikeleze okanye lutyibilike.

Kubathengi abafumana umthamo, cela umenzi ukuba akunike umgangatho wezinto ezisetyenziswa ngumqhubi, ubukhulu beplati ukuba zifakwe ebhotileni, kunye netafile enobukhulu bemodeli nganye. Umthengisi othembekileyo uya kwabelana ngetshathi epheleleyo enoluhlu lwe-conductor, umngxuma westud, ubungakanani bebharele, kunye nobude obupheleleyo, ukuze iqela lakho lobunjineli likwazi ukucacisa inxalenye echanekileyo ngaphambi kokuthunyelwa kokuqala.

Ukwenza izinto zilunge, ngalo lonke ixesha

Ukukhetha iintambo zentambo ze-SC kuxhomekeke kumanani amathathu owalawulayo: icandelo elinqamlezileyo le-conductor, ububanzi be-stud, kunye nombane oza kuthwala i-joint. Funda ikhowudi yenxalenye ngokuchanekileyo, uyifanise nentambo yokwenyani endaweni yoqikelelo olujikelezileyo, kwaye ugxininise ubhedu olufakwe kwi-tin olunobukhulu obaneleyo bodonga kuyo nayiphi na isekethe edinga amandla. Yenza loo nto, kwaye uqhagamshelo lwakho luhlala lupholile, luqinile, kwaye luthembekile ubomi bonke bofakelo. Ukuba awuqinisekanga ukuba zeziphi iimodeli ezifanela uluhlu lweentambo zakho, thumela ubungakanani be-conductor yakho kunye nobukhulu be-stud kwiqela lethu kwaye siya kucebisa ii-SC lugs ezichanekileyo kunye noseto lwe-crimp kwisicelo sakho.
