Xa iinjineli zibuza, “Sisiphi esona sixhobo sithembekileyo se-200-amp busbar kwiipaneli zemizi-mveliso eshukumayo?”— tbhk200 iza ngokukhawuleza. Akunjalo njengegama lentengiso, kodwa njengenxalenye esiyibonileyo iphila iminyaka emithathu yokuthunyelwa kwiikhabhathi zokulawula ukutya okuziinkozo, iibhokisi zokudibanisa ilanga ezivezwe kwimijikelo ye-UV yasentlango, kunye nejenereyitha eshukumayo eshukumayo ijikeleza kwiindlela zemigodi ezingagangathwanga.
Sivavanye abanini beebhasi abahlanu abalinganiswe kwi-200 A ngaphezu kweenyanga ezintandathu-ukulinganisa i-thermal drift kwi-150% yomthwalo, ukukhupha amandla emva kwee-2,000 ze-vibration cycles (nge-ISO 16750-3), kunye nokugcinwa kwexesha elide le-clamping phantsi kwebhayisikili ye-thermal (-40 ° C ukuya + 85 ° C). I tbhk200 yayikuphela koyilo olubambe i-torque ngaphakathi kwe-± 3% kuzo zonke iimvavanyo-kwaye ayizange ifune ukuqiniswa kwakhona emva kweeyure zokuqala ze-72 zokusebenza.
Kutheni i-tbhk200 ime ngaphandle kwiPaneli yokwenyani eyakhayo
Uninzi lwabaphathi beebhasi abaphumeleli kwireyithingi yangoku-kodwa kwi-interface: uxinzelelo olungalinganiyo, ukunyuka kwezinto eziphathekayo, okanye ukungahambi kakuhle ngexesha lofakelo lwentsimi. I tbhk200 isombulula oku ngeenyaniso ezintathu ezakhelwe ngaphakathi:
I-asymmetric ye-dual-spring clamping: Intlakohlaza enye icinezela ngokuthe nkqo ngokuchasene nebhasi; eyesibini ibandakanyeka ecaleni, itshixa ibha kwindawo phambi kokuba itorque isetyenziswe ngokupheleleyo. Sabukela amagcisa eyifaka ivalwe amehlo kwipaneli ethambekileyo-isafikelela kwindawo epheleleyo yoqhagamshelwano. Izindlu ezibandayo ezenziwe ngentsimbi engenasici (AISI 301, 0.8 mm ubukhulu): Ayinasitampu-kwaye-gotywa, kodwa izotywe nzulu kwipasi enye. Oko kuphelisa amanqaku oxinzelelo lomthungo apho ukudinwa kuqalwa khona. Sahlulahlula iiyunithi emva kweenyanga ezili-18 kwigumbi leMCC elifumileyo lesityalo sobisi-ziro microcracks kwiiflange ezinyukayo. Imikhono ye-insulator yokuzimela eyenziwe kwi-UL94 V-0 i-fiberglass-yokuqiniswa kwe-PBT: Bacinezela i-radially phantsi kwe-torque ye-bolt, babambe i-busbar ngaphandle kwe-slippage-kwaye babuyiselwe ngokupheleleyo emva kokuphindaphinda ukukhulula / ukuqinisa. Akukho mnye umnini kule klasi unikeza>500 imijikelo ye-torque kwakhona ngaphandle kokuguqulwa kwe-insulation. Nantsi into abasebenzisi abangayiqondiyo de baxazulule iingxaki: I tbhk200's 12.5 mm isithuba somngxunya wokufakela asinto yanto. Ihambelana ne-DIN 43671 ye-busbar centerlines-kwaye igwema ukuphazamiseka kunye nezibiyeli eziqhelekileyo ze-DIN zokukhwela umzila. Sithathe indawo yabagcini abasilelayo ukusuka kwezinye iibhrendi ezintathu ukuze sifumane loo 0.3 mm yokukhutshwa komda kufutshane neebhloko zetheminali.
Apho iwela khona ngokufutshane (kwaye xa uhamba nini)
Ezinye iinjineli zicinga ukuba "200 A" kuthetha ukuhambelana jikelele. Akunjalo. I tbhk200 yamkela kuphela iibhasi ze-rectangular copper okanye i-aluminium ubukhulu be-15 × 3 mm ukuya kwi-25 × 10 mm. Ayiyi kubamba imivalo engqukuva, imfumba elayitiweyo, okanye iibhasi zebhasi ezityebileyo kune-10 mm-nokuba ireyithingi yangoku iyalingana.
Sibone iintsilelo ezimbini zentsimi ezibotshelelwe ngokuthe ngqo kwii-specs ezingahambelaniyo:
Umthengi uyisebenzise ngebhasi ye-aluminium eyi-30 × 8 mm. Umphezulu wokubamba ugobe ngokubonakalayo ku-130 A. Iqondo lobushushu kwindawo edibeneyo linyuke nge-22°C ngaphezu kwe-ambient—yanele ukuthomalalisa ukugquma ucingo olukufutshane. Elinye iqela layifakela kwiibhasi zentsimbi. Ukufuduka kweZinc kubangele ukugoba kwizindlu ezingenasici phakathi kweentsuku ezingama-90. Ukulungiswa? Cacisa ubhedu olungenanto okanye iibhasi ze-tin-plated-okanye uqinisekise ukuhambelana nomvelisi kuqala. Kwakhona: Akukho lug yokumisa edibeneyo. Ukuba uyilo lwephaneli yakho ifuna ukunyuswa okudityanisiweyo, uya kufuna isitudi sokumisa sangaphandle se-M6 kunye newasha yeenkwenkwezi. Musa ukuthembela kwindlu ngokwayo-ihlukaniswe ngokuyila.
Ukufakela kuyakhawuleza-kodwa kuphela xa uhlonipha ulandelelwano
I tbhk200 iinqanawa ezine-M6 × 16 mm Iibholiti zeKlasi ye-12.9, i-EPDM washers, kunye ne-torque specs eprintwe ngqo kwi-package. Kodwa "ukukhawuleza" kuxhomekeke ngokupheleleyo kulandelelwano:
Slayida i-busbar ngokupheleleyo kumhlathi ongezantsi-ide iphume ngaphandle kwindawo yokumisa. Qinisa ibholithi yokubambelela ephezulu ukuya kwi-5.5 N · m kuqala. Oku kucwangcisa iqhaga elisecaleni. Emva koko qinisa iibholithi ezisecaleni ukuya kwi-7.0 N · m ngokulandelelana kwediagonal. Ukutsiba oku kubangele i-37% yemiba yolungelelwaniso kwibhetshi yethu yovavanyo. Sibeke ixesha 12 techs field ukuyifaka kubanda. Ixesha eliphakathi: 42 imizuzwana kwiyunithi nganye. Olona lucothayo luthathe imizuzu eyi-2.1-kuba baqinise iibholiti zecala phambi kokuba ibambe phezulu. Loo nto yayonakalisa indlu kancinane, ifuna ukuchithwa kunye nokutshintshwa.
Ngubani ofanele ayithenge—yaye ngubani omele ayitsibe
Ufuna i tbhk200 ukuba:
Isicelo sakho sifuna uqhagamshelo oluphinda-phindayo lwe-200 A kwimo ephathwayo, kwindawo ezothuka kakhulu (umzekelo, izilawuli zezolimo, ii-inverters ezingaphandle kwegridi, iijensethi ezifakwe kwinqwelwana). Wakha kwi-IEC 61439-1 kwaye ufuna idatha ebhaliweyo yokusebenza kwe-thermal-hayi nje "ilinganiselwe i-200 A." I-Botou Haijun ibonelela ngeengxelo ezipheleleyo zovavanyo: ukunyuka kweqondo lobushushu ngokuchasene namagophe angoku, iinkuni zokusinda ze-vibration, iziphumo zokutshiza ngetyuwa (iiyure eziyi-1,000, akukho mhlwa obomvu). Uqhuba umthamo ophantsi, umxube ophezulu wemveliso kwaye awukwazi ukuhlawula ukulibaziseka kwezixhobo. Akukho MOQ. Sa-odola iiyunithi ezili-17 zokuqhuba kweprototype-kwaye sazifumana kwiintsuku ezili-11, kunye neengxelo ezipheleleyo zeCMM ezibandakanyiweyo. Kufuneka uyitsibe ukuba:
Uyila iiphaneli zabathengi eziveliswe ngobuninzi apho ixabiso-kwiyunithi nganye liqhuba izigqibo. Kwi-$ 8.40 / iyunithi (i-FOB Botou), i-2.3 × i-pricier kunezinye iindlela ezisisiseko ezinesitampu-zilungelelaniswa kuphela ngokuphila ixesha elide kunye nokuphepha ukungaphumeleli. Iibhasi zebhasi zakho zidlula ubukhulu be-10 mm okanye sebenzisa i-alloys ezingekho mgangathweni njenge-nickel yobhedu okanye i-beryllium-copper. Udinga i-RoHS-ehambelanayo neplating ngaphaya komgangatho oqhelekileyo-kwaye awukaziqinisekisi iinketho zokugquma ngaphambili. I tbhk200 ayingoyena mnini webhasi yexabiso eliphantsi kwimarike. Yiyo eyeka ukubiza imali emva kwenyanga yesithandathu-xa iiyunithi zabakhuphisana ziqala ukubonisa iindawo ezishushu, ukukhulula, okanye ukunxitywa kwe-insulation. Amandla ayo alele kwindlela eliphatha ngayo ilizwe lokwenyani: ukungcangcazela, ukujingiwa kwe-thermal, ukuphuculwa kwebala, kunye nokuvezwa kweminyaka emininzi. Kungenxa yoko le nto ibonakala kwi-schematics evela kwi-automation integrators yaseJamani, ii-EPC zelanga zaseSaudi, kunye ne-OEMs yefama yefama ye-OEMs-zonke ziyichaza ngenxalenye yenombolo, kungekhona inkcazo.
Ukuba indawo yolawulo yakho elandelayo idinga uqhagamshelo oluhlala luqinile, hlala upholile, kwaye uhlale ubhalwe—qala nge tbhk200. Emva koko qinisekisa imilinganiselo yakho yebhasi, khankanya imathiriyeli yakho, kwaye ucele impendulo yeDFM ngaphambi kokusika isinyithi. Ukuchaneka kuqala apho.
