Into ethokozisayo yathola ukuthi kuzixhumi eziningi ezisawolintshi eziphezulu ze-high-voltage, ezisetshenziswe ezimotweni isikhathi esithile, igobolondo lepulasitiki libonakala liyinto emhlophe, futhi lesi simo asiyona into ehlukile, hhayi umndeni walesi simo, ikakhulukazi imoto yokuhweba.
Amanye amakhasimende angibuze ukuthi ingabe lokhu kuthinta ukusetshenziswa kwawo. Ingabe bukhona ubungozi? Ingabe ithinta impilo yesevisi?
Ngaphambi kokuba uphendule lo mbuzo, bhala imibuzo embalwa ukuze uthole impendulo:
1. Kungani kudingekile ukusebenzisa umbala osawolintshi kuzixhumi zamandla kagesi aphezulu? Kungenzeka yini ukungayisebenzisi?
2. Hlobo luni lwempahla isixhumi ngokuvamile igobolondo plastic? Uvelaphi umbala osawolintshi?
3. Ngenxa yokusetshenziswa kwezimo ezikhethekile,? Ingabe ikhona inkinga ngokufaka isicelo sesikhathi eside?
4. Lokhu kusenza sicabangeni futhi yini okufanele siyinake?
Kungani izixhumi zamandla kagesi aphezulu zidinga ukusebenzisa umbala osawolintshi? Ngeke yini sikusebenzise?
Ukusetshenziswa kwewolintshi njengombala oyisixwayiso wamandla kagesi aphezulu kuthathwa ngokuthi “umkhuba wamazwe ngamazwe”, isibonelo, Ikhodi Kagesi Kazwelonke Yase-US (NEC) yamukele owolintshi njengombala odingekayo wezintambo zikagesi eziphezulu; kusukela ngasekupheleni kwawo-90's lapho ama-HEV ethandwa kancane kancane kuma-EVs, iwolintshi uye wasetshenziswa njengekhodi yombala eyisixwayiso yamandla kagesi aphezulu kuma-xEV, asetshenziselwa ukuchaza izintambo zikagesi ophezulu nezixhumi.izintambo ezinamandla kagesi nezixhumi; lolu hlelo lombala oludonsa amehlo lukhomba ukuthi yiziphi izingxenye zeyunithi ye-voltage ephezulu akufanele zithintwe ngaphandle kokuqeqeshwa okufanele kokuphepha kanye nemishini yokuzivikela yomuntu siqu.
Iyini i-automotive-grade high voltage? “Ibanga lezimoto” “umqondo wamandla kagesi aphezulu” ngokuvamile “isigaba samandla kagesi “B” ngokwencazelo ye-ISO 6469-3, ngokuvamile ene-voltage yokusebenza engu> 60 V kanye ≤ 1500 V DC noma 30 V kanye ≤ 1000 V AC . > 30 V kanye no-≤ 1000 V AC, ngokwezinga elithi “Amakhebula ebhasi anamandla kagesi aphezulu angekho endlini azokhonjwa ngekhava enombala “owolintshi” Ibhasi, kulokhu, lisho umhlangano, equkethe nezixhumi;
Ngokwamazinga okuxhunywa, kungakhathaliseki ukuthi izindinganiso ezinkulu ze-OEM, noma i-Europe isihlakaziwe “izindinganiso zochungechunge lwe-LV” noma amazinga afanayo e-USCAR, (LV215 216 USCAR20 SAE1742, njll.) abeke ukuthi isixhumi esinamandla amakhulu okubhala ikhodi umbala owolintshi kanye inombolo yekhadi lombala ibeka izidingo ze-RAL 2003, 2008 kanye no-2011; lapho i-RAL 2003 ikhanya kakhulu, i-RAL 2011 ibomvu futhi imnyama kakhulu, kanti i-RAL 2008 iphakathi. Izidingo ngokuvamile zichazwa ngokuthi yi-RAL 2003, 2008, kanye no-2011; lapho i-RAL 2003 ikhanya kakhulu, i-RAL 2011 ibomvu futhi imnyama kakhulu, futhi i-RAL 2008 phakathi kwakho kokubili, kuyilapho okuwolintshi kudinga ukuhlangabezana nombala weminyaka engaphezu kweyi-10 ngaphandle kokushintshashintsha.
Ngakho umbala wewolintshi umthetho oyisisekelo womgwaqo, uma wenziwe ngensimbi, ngokuvamile nawo udinga ukumakwa endaweni esobala yelebula lesexwayiso se-voltage ephezulu, ngakho-ke ayikwazi ukuba yiwolintshi? Ngokuvamile akunjalo, ngoba izimiso zokuphepha ezifanele zinganqatshwa.
Hlobo luni lwezinto ezisetshenziselwa izixhumi ezinamagobolondo epulasitiki? Uvelaphi umbala osawolintshi?
Amagobolondo okuxhuma ngokuvamile enziwe ngezinto ze-polyurethane, ezivame ukusetshenziswa i-PA66 PBT, njll., amagobolondo epulasitiki ajwayelekile adinga ukuhlangabezana nezidingo zokufakwa kwesistimu, futhi ngesikhathi esifanayo adinga ukuba nezici ezithile zomzimba, njengamandla anele, ukumelana nezinyembezi. , ukuqina, njll., kodwa futhi kudingeka ube nezici zokunqanda ilangabi, ngakho-ke inani elijwayelekile le-CTI linezidingo ezikhethekile, ngokuvamile, abakhiqizi bazosebenzisa izinto zenayiloni ukwandisa ezifanele Ngokuvamile, abakhiqizi bazosebenzisa impahla enayiloni enomucu wengilazi ofanele njengezinto zayo, njenge-PA66+30%GF_V0 noma i-PBT.
Umbala osawolintshi uvame ukwakhiwa ngezindlela ezi-2, eyodwa iyizinhlayiya zepulasitiki ezimhlophe kanye nephesenti elithile lokuxutshwa kwempushana yombala, ngokuvamile umbala ongokwezifiso, umbala wakamuva uzinze kakhulu, futhi izindleko ezihambisanayo nazo ziphakeme, abakhiqizi bezinto ezibonakalayo kufanele ukuhlangabezana nezidingo ezijwayelekile ezihambisanayo zombala wangokwezifiso, njenge-BASF, isiCelanese nokunye.
Ngenxa yokusetshenziswa kwezimo ezikhethekile,? Ingabe zikhona izinkinga ngezicelo zesikhathi eside?
Inkinga ekuqaleni kwe-athikili itholakala ebhokisini lebhethri ngaphandle, lidaluliwe, indawo ichayeka ekukhanyeni kwelanga unyaka wonke, futhi eduze nesondo, inertia yesondo yezinto ezingcolisa umzimba zijikijelwa phezulu iphesenti elithile elinamathiselwe kokubalulekile, ngokusekelwe kulokhu, okokuqala, amathuba okuba mhlophe makhulu ngenxa yokuchayeka isikhathi eside emazingeni okushisa aphezulu kanye nokukhanya kwelanga, okusheshisa ijubane lokuguga kwawo, okuholela ekubeni mhlophe, futhi ngesikhathi esifanayo, i-UV kanye neminye imisebe izobangelwa ukusabela kwamakhemikhali nobuso bezinto ezibonakalayo, okuholela ekushesheni kokumhlophe kwempahla. Ngasikhathi sinye, imisebe ye-ultraviolet neminye imisebe izophinde ibangele ukusabela kwamakhemikhali ngendawo ebonakalayo, ngaleyo ndlela iholele ekusheshisweni kwezinto ezibonakalayo kanye nokuba mhlophe, ngaphezu kokuvezwa nokusondela kwemoto kuzokwenza ukuthi ibe maningi amathuba okuba idliwe yi-asidi. -eziqukethe ukungcola, okuzoholela ekuwohlokeni okusheshayo kwama-molecule ezinto ezibonakalayo ku-asidi ngaphansi kokusekelwa kwe-chemical reaction whitening.
Sekukonke, ukwenziwa mhlophe kwempahla kusho ukuthi kunengozi engaba khona "yokufiphala" kanye "nokonakaliswa kwezakhiwo zikagesi", okuzothinta impilo yayo yesevisi futhi kwandise ithuba lokwehluleka komkhiqizo uma kuqhathaniswa nezixhumi ezijwayelekile, njengokuqhekeka ngemuva komthelela izinto zangaphandle, njengamatshe. Uma kuqhathaniswa nezixhumi ezivamile, maningi amathuba okuthi umkhiqizo uhluleke, njengokungenwa kalula ukuqhekeka ngemva komthelela wamatshe nezinye izinto zangaphandle, ukuba ne-impedance empofu uma imanzi, kanye nokuba sengozini yokuqhekeka.
Ukusenza sicabange ngalokho okudingeka sinakwe?
Ngokombono wokuthuthukiswa kwezixhumi zamandla kagesi aphezulu, izixhumi eziya ekwenziweni okuncane kakhulu, ukuhlanganiswa (izinto ezisetshenziswa kalula ukufaka okuxhunywana nogesi okwengeziwe) okungasindi kakhulu (isakhiwo esihlangene kakhudlwana, usayizi omncane, ukujiya okuzacile, njll.) ithrendi, lokhu komkhiqizo ongaphansi ucwaningo lwezobuchwepheshe kanye nempumelelo kubeka phambili izidingo eziphakeme; isibonelo, amatheminali okuxhumana amelana nemihuzuko (izinto zokucwenga, ukukhetha kwe-substrate, nolunye ucwaningo) nokunye.
Ngasikhathi sinye, izinto zepulasitiki nazo zibeka phambili izidingo eziphakeme, indawo yokusebenza ebanzi phakathi nezidingo zomjikelezo wokuphila, izidingo eziphakeme ze-CTI, kanye no-0.4mmV0 ngaphansi kwezidingo zezakhiwo zikagesi, wonke umjikelezo wokuphila wokuzinza kombala, izinto zokwakha. , ukumelana nokushisa okuphezulu, ukushisa okuphezulu kwezinto ezibonakalayo, isidingo sokugxila ezithasiselweni ezibonakalayo ekugqweni kukagesi koxhumana nabo, ukuzinza komzimba wezinto ezibonakalayo ekusetshenzisweni kwesikhathi eside kwesakhiwo samandla Ukuzinza kwe ukusetshenziswa kwezinto ezibonakalayo ezindaweni ezinokhahlo, njll...
