Inkathi entsha yeNew Energy Automobile Imboni ifaka phakathi umsebenzi wezinguquko ezimboni kanye nokuvikelwa kwemvelo yasemkhathini, okutholakale kakhulu izindwangu zamandla ezimboni, okuthuthukiswa kwezinye izimboni ezihlobene nocwaningo kanye nasekuthuthukisweni kwamakhekhe aphezulu ezitolo ezinkulu zezimoto zikagesi. Izintambo eziphakeme ze-voltage zezimoto zikagesi zinezidingo eziphezulu zokusebenza kuzo zonke izici, futhi kufanele zihlangabezane ne-RohSB Standard, Flame Retardant Ibanga le-UL94V-0 nokusebenza okujwayelekile. Leli phepha lingenisa izinto zokwakha nokulungiswa kobuchwepheshe bezinsimbi eziphakeme ze-voltage zezimoto zikagesi.
1.I-matering of high voltage ikhebula
(1) I-Conductor's Material of Cable
Njengamanje, kunezinto ezimbili eziphambili ze-Cable Conductor ungqimba: ithusi ne-aluminium. Izinkampani ezimbalwa zicabanga ukuthi umnyombo we-aluminium zinganciphisa kakhulu izindleko zabo zokukhiqiza, ngokungeza i-Copper, i-Iron, i-Silico, ukumelana nokwelashwa okuningana, ukubhekana nokuvuselelwa kukagesi, ukuze kufezeke ukusebenza komthamo ofanayo, ukufeza umphumela ofanayo nabaqhubayo beCopper noma kangcono. Ngakho-ke, izindleko zokukhiqiza zisindiswa kakhulu. Kodwa-ke, amabhizinisi amaningi asenza ithusi njengezinto eziphambili ze-Conductor ungqimba, okokuqala, ukumelana kwethusi kuphansi, bese kuba khona ukusebenza kwethusi kungcono kunalokho kwe-aluminium ezilinganisweni ezifanayo, ukusetshenziswa okuphansi kwamandla, ukusetshenziswa okuphansi kwamandla kanye nokwethenjwa okuqinile. Njengamanje, ukukhethwa kwabaqhubi ngokuvamile kusetshenziswa abaqhubi abajwayelekile abajwayelekile abangu-6 (ububanzi be-single Copper yethusi kumele bube bukhulu kune-25%, ububanzi be-monofilay bungaphansi kuka-0.30) ukuqinisekisa ukuthamba nokuqina kwe-monofilament yethusi. Ithebula 1 libala amazinga okumele ahlangatshezwe ngezinto ezisetshenziswayo zomqalisi we-Copper.
(2) Izinto zokufaka ezifakwayo zezintambo
Imvelo yangaphakathi yezimoto zikagesi iyinkimbinkimbi, ekukhetheni kwezinto zokwakha ezifakwayo, ngakolunye uhlangothi, ukuqinisekisa ukusetshenziswa okuphephile kokufakwa kongqimba okufakwayo, ngakolunye uhlangothi, ngangokunokwenzeka ukuze ukhethe izinto zokwakha ezilula futhi ezisetshenziswa kabanzi. Njengamanje, izinto ezisetshenziswayo ezisetshenziswayo ziyi-polyvinyl chloride (PVC),I-polyethylene exhumene nesiphambano (i-XLPE), irabha le-silicone, i-thermoplastic elastomer (TPE), njll., Futhi izakhiwo zazo eziyinhloko zikhonjiswa kuThebula 2.
Phakathi kwazo, i-PVC iqukethe ukuhola, kepha umyalo we-rohs wenqabela ukusetshenziswa kwe-lead, i-mercury, i-cadmium, i-hexvalent chromium, i-PVCROMINED BIPHERS (PBBE) kanye nezinye izinto eziyingozi, i-ailpe ruble, i-TPE kanye nezinye izinto ezinobungane zemvelo.
(3) I-Cable Shiepling Layer Material
Isendlalelo sokuvikela sihlukaniswe izingxenye ezimbili: ungqimba oluvikelekile lwe-semi-hightive kanye nongqimba oluvikelekile olunamafutha. Ukumelana nevolumu okuvikelayo kokuvikela okuvuthayo ku-20 ° C no-90 ° C kanye ngemuva kokuguga kuyinkomba ebalulekile yezobuchwepheshe ukukala impahla yokuvikela, enquma ngokungaqondile impilo yesevisi yekhebula eliphakeme le-voltage. Izinto zokuvikela ezijwayelekile ezihamba nge-semi-hightive zifaka i-ethylene-propypene rubber (EPR), i-polyvinyl chloride (PVC), kanyepolyethylene (pe)izinto zokwakha ezisekelwe. Endabeni yokuthi impahla eluhlaza ayinanzuzo futhi izinga lekhwalithi alikwazi ukwenziwa ngcono esikhathini esifushane, izikhungo zokucwaninga zesayensi kanye nabenzi bezinto ezibonakalayo zigxile ocwaningweni lwe-Distring Technology, futhi bafuna ukwenziwa okusha kokuvikelwa kokuvikelwa kwentambo.
Inqubo yokulungiselela kagesi ka-2.High Voltage
(1) ubuchwepheshe bomqhubi we-conductor
Inqubo eyisisekelo yekhebula yenzelwe isikhathi eside, ngakho-ke kukhona nokucaciswa kwazo okujwayelekile embonini namabhizinisi. Enqubweni yokudweba nge-wire, ngokuya ngemodi yokungenisa ucingo olulodwa, imishini ethambile ingahlukaniswa ngomshini wokuhlanza okungapheli, umshini wokuhlunga ongapheli kanye nomshini wokuhlanza okungapheli / ongabonakali. Ngenxa yokushisa okuphezulu kwe-crystallization of Copper conductor, izinga lokushisa nesikhathi esiseduze, kufanelekile ukusebenzisa imishini yomshini yokuhlanza okungapheli ukuze uqhubeke nokudonsa okuqhubekayo ukuze uthuthukise i-monjire yokudweba okuqhubekayo. Njengamanje, i-polyethylene exhumene ne-polyethylene cable (XLPE) isuse indawo kawoyela ngokuphelele ikhebula lamafutha aphakathi kwamazinga angu-1 no-500kv Voltage amazinga. Kunezinqubo ezimbili ezijwayelekile zokwakheka zokwakheka kwabaqhubi be-XLPE: Ukuhlanganiswa kwendilinga kanye nokusonteka kocingo. Ngakolunye uhlangothi, umnyombo we-wire ungakugwema izinga lokushisa eliphakeme kanye nengcindezi ephezulu epayipini elixhumeke kakhulu ukuze ucindezele impahla yalo yokuvikela kanye nokufakwa kwegebe lokufakelwa kwi-wire wire futhi kubangele imfucuza; Ngakolunye uhlangothi, kungavimbela nokufakwa kwamanzi eceleni komqhubiyali ukuqinisekisa ukusebenza okuphephile kwekhebula. Umshayeli weCopper uqobo uyisakhiwo esijikelezayo esijikelezayo, esikhiqizwa kakhulu ngomshini ojwayelekile wohlaka, umshini wokuhlanza iFork, njll. Uma uqhathaniswa nenqubo yokusebenzisana eyindilinga, kungaqinisekisa ukusungulwa komjikelezo okujikelezayo.
(2) Inqubo Yokukhiqiza I-XLPE Cable Insulation
Ukuze kukhiqizwe ikhebula le-voltage XLPE eliphakeme, i-Conv eyomile yokuxhumanisa (i-CCV) kanye ne-vertical drest cross-licking (VCV) izinqubo ezimbili zokwakha.
(3) Inqubo yokukhishwa
Phambilini, abakhiqizi bekhebula basebenzise inqubo yokukhishwa kwesibili ukukhiqiza umnyombo wokufaka amakhebula, isinyathelo sokuqala ngasikhathi sinye esidikibazayo ngesihlangu, bese silisebenzisa ngesihlangu sekhebula, sibekwe isikhathi sokufakwa kwekhebula. Ngesikhathi seminyaka yo-1970, inqubo yokukhishwa kwengqimba engu-1 + 2 yavela endaweni efakiwe ye-wire, evumela ukuvikela kwangaphakathi nangaphandle nokufakwa kwenqubo eyodwa. Inqubo yokuqala ikhipha isihlangu somshayeli, ngemuva kwebanga elifushane (2 ~ 5m), bese ikhipha isivikelo kanye nesihlangu sokufakelwa esihlahleni somshayeli ngasikhathi sinye. Kodwa-ke, izindlela ezimbili zokuqala zinezinkinga ezinhle kakhulu, ngakho-ke ngasekupheleni kweminyaka yama-1990s, abahlinzeki bemishini yokukhiqiza amakhebula bethula inqubo yokukhiqiza ekhishwa abathathu, ekhipha ukulangazelela komshayeli, ukufakwa kanye nokuvikelwa kokuvikelwa ngasikhathi sinye. Eminyakeni embalwa edlule, amazwe aphesheya abuye ethule ikhanda elisha le-barrel ekhishini le-mesh Plate, ngokulinganisa i-Screw Head Cavity Flow Presstion yokunciphisa ukuncaciswa kwezinto ezibonakalayo futhi, esikhundleni sokuyeka ukukhiqizwa kokucaciswa komklamo wekhanda nakhonga kakhulu futhi kuthuthukise ukusebenza kahle.
3. Isiphetho
Izimoto ezintsha zamandla zinamathuba amahle okuthuthuka kanye nemakethe enkulu, zidinga uchungechunge lwemikhiqizo ephezulu ye-voltage cable ngamandla aphezulu, ukumelana nokuvikelwa kwe-electromagnetic, impilo yokugoba, ukusebenza kahle kokukhiqizwa kanye nokunye okusebenzayo. I-Electric Vehicle High-Voltage Cable impahla nenqubo yayo yokulungiselela inamathemba abanzi entuthuko. Imoto kagesi ayikwazi ukuthuthukisa ukusebenza kahle kokukhiqiza futhi iqinisekise ukusetshenziswa kokuphepha ngaphandle kwekhebula eliphakeme le-voltage.
