Incazelo Yomkhiqizo

Izintambo ezivikelwe ngamaminerali ziyizintambo ezenziwe ngezinto ezingaphili.Ungqimba olungaphandle lwekhebula luwumgodla wethusi ongenamthungo, futhi kukhona ungqimba oluhlanganiswe ngokuqinile lwe-magnesium oxide insulating phakathi komgodla kanye nomgogodla wensimbi.
Ikhebula lamaminerali liwumugqa oyinhloko wobunjiniyela besimanje bokwakha, futhi iyikhebula elingenakushiswa ukuze kuqinisekiswe ukudluliswa kwamandla.Ifanele izintambo zikagesi ezifana nokunikezwa kwamandla omlilo, ukunikezwa kwamandla okunganqamuki, kanye nogesi wezibani eziphuthumayo.
I-bttz yekhebula leminerali ngemuva kwalokho iye yandisa amamodeli amasha ahlukahlukene njengekhebula le-BBTRZ, ikhebula le-YTTW, intambo ye-BTLY, njll., wonke athuthukiswayo futhi athuthukiswa ngesisekelo sezintambo zamaminerali ze-bttz.Izintambo ezingashi zingabizi zingasetshenziswa kumaphrojekthi amaningi.
Kuhlelo lwamanje lokusabalalisa amandla okwakha, izintambo ezifakwe amaminerali zisetshenziswa kabanzi futhi kabanzi, futhi ukumelana nomlilo, ukuqina, ukuphepha, ukwethembeka kanye nomnotho akukwazi ukushintshwa yizintambo zamandla zendabuko.
Ngaphansi kwezimo zomlilo, izintambo ze-mineral insulated azikwazi kuphela ukuqinisekisa ukunikezwa kwamandla okucisha umlilo phakathi nesikhathi somlilo (ngaphezu kwemizuzu engu-180), kodwa futhi ngeke kubambezeleke ukusha, ukukhiqiza umusi, noma ukukhiqiza izinhlekelele zesibili, ngaleyo ndlela zithole isikhathi esibalulekile somlilo. hlenga.Kuyabonakala ukuthi izintambo ze-mineral insulated ziyadingeka ekwakheni ukuvikela umlilo.
Uma kuqhathaniswa nezintambo eziphilayo, izintambo zamaminerali ziyakwazi ukumelana nezinga lokushisa eliphezulu, zingashi, zingaqhumi, futhi azishi (zingasebenza ngokuqhubekayo isikhathi eside ku-250 ° C, futhi zingasebenza isikhathi esifushane esingu-30min endaweni yomkhawulo. ye-1000°C), futhi inomthamo omkhulu wokuthwala, ububanzi obuncane bangaphandle, Inezinzuzo zamandla aphezulu emishini, impilo ende yesevisi, futhi ngokuvamile asikho isidingo sezintambo ezizimele eziphansi.Izintambo ezivikelwe ngamaminerali zisetshenziswa kakhulu ezimbonini zamandla enuzi, i-metallurgy, imboni yamakhemikhali, izimayini, i-aerospace, izakhiwo eziphakeme kakhulu, izikhumulo zezindiza, amadokodo, izitimela ezingaphansi komhlaba nezinye izindawo lapho ukugeleza kwabagibeli kugxilwe khona, ukuvikela amaphampu omlilo, amakheshi omlilo, imithwalo ebalulekile. , imiyalelo yokuphuma ezimweni eziphuthumayo, Kanye nogesi wezinto ezibalulekile zokucisha umlilo njengokuvimbela umlilo kanye nezinhlelo zokukhipha intuthu.

Imingcele yezobuchwepheshe yomkhiqizo

Izici zomkhiqizo

(1) Ukumelana nomlilo:
I-Copper ne-magnesium oxide yizinto ezingaphili ezisetshenziswa kumakhebula afakwe kumaminerali.Lolu hlobo lwekhebula ngeke lushise noma lusekele ukusha, futhi lisengaqhubeka nokusebenza uma luseduze nelangabi.I-copper sheath incibilika ku-1083 ℃, kuyilapho i-magnesium oxide insulating material iqiniswa ku-2800 ℃.
(2) Izinga lokushisa eliphezulu lokusebenza
Izintambo ezifakwe amaminerali zingamelana namazinga okushisa aqhubekayo afinyelela ku-250 ℃.Kodwa-ke, esimweni esiphuthumayo, ikhebula lingaqhubeka nokusebenza isikhathi esifushane ekushiseni okuseduze nendawo yokuncibilika ye-sheath yethusi.
(3) Impilo ende
Izinto ze-Inorganic ezisetshenziswa ezintamboni ezifakwe amaminerali zingaqinisekisa ukuzinza, impilo ende yenkonzo kanye nokumelana nomlilo kwezintambo.
(4) Ubufakazi bokuqhuma
Izinto zokuvikela ezihlangene kakhulu ezintanjeni ezifakwe amaminerali zingavimbela ukudlula kwesitimu, igesi nelangabi phakathi kwezingxenye zemishini exhunywe ezintanjeni.
(5) Ububanzi obuncane obungaphandle
Ububanzi bekhebula le-mineral insulated lincane kunalelo lamanye amakhebuli anesilinganiso esifanayo samanje.
(6) Ingangeni manzi
Uma ikhebula le-mineral insulated licwiliswa ngokuphelele emanzini, ikhebula le-mineral insulated lingaqhubeka nokusebenza ngomgodla walo wensimbi ongenamthungo.
(7) Amandla aphezulu emishini
Amakhebuli afakwe amaminerali aqinile futhi angamelana nokulimala okukhulu kwemishini ngaphandle kokulimaza ukusebenza kwawo kagesi.
(8) Umthamo omkhulu wamanje wokuthwala
Emakhebulini anesigaba esifanayo, izintambo ezivalwe ngamaminerali zidlulisa amandla aphezulu kunezinye izinhlobo zezintambo.Ngesikhathi esifanayo, ikhebula le-mineral insulated lingamelana nokugcwala okukhulu.
(9) Isilinganiso sephutha lesifunda esifushane
Emazingeni okushisa afanayo, isilinganiso sephutha lesekethe emfishane yezintambo ezivalwe ngamaminerali ngokusobala siphakeme kunezinye izinhlobo zezintambo.
(10) Ukugawula
Kumakhebula e-mineral insulated, i-conductor yokuzimela yokuzimela ayidingeki, ngoba i-copper sheath esetshenziswe kule ntambo iye yadlala indima yomqhubi we-grounding futhi inganikeza ukumelana okuhle kakhulu kokuphansi komhlaba.Ukuze kufakwe izintambo ze-grounding sheath loop (ESR), umgodla wethusi wangaphandle ungasetshenziswa njengekhondatha ephansi futhi engathathi hlangothi ohlelweni lwe-MEN (multiple grounded neutraled neutral).
(11) Ukumelana nokugqwala okuphezulu
I-copper sheath ye-mineral insulated cable inokumelana nokugqwala okuphezulu.Emadivaysi amaningi, akudingi ukuthatha izinyathelo zokuzivikela ezengeziwe.Ezindaweni lapho umgodla wethusi wekhebula usengozini yokugqwala kwamakhemikhali noma ukungcoliswa okukhulu kwezimboni, ikhebula elivikelwe ngamaminerali kufanele livikelwe ngepulasitiki yangaphandle.
