Indlela YokuchongaIleli yeCableIinkcukacha？
Ukukhetha imithetho efanelekileyo yokukhethaileli yentambolinyathelo elibalulekileyo kwiiprojekthi zocingo lombane, elichaphazela ngokuthe ngqo ukhuseleko lwesekethe, ukuchithwa kobushushu, kunye nokukhula kwenkqubo. Ubungakanani obufanelekileyo bufuna ukuqwalaselwa ngokubanzi kwemilinganiselo eyahlukeneyo, kubandakanya amandla oomatshini, ukusetyenziswa kwendawo, indawo yokusebenza, kunye neemfuno zolondolozo lwexesha elide.
1. Uvavanyo loMthamo othwala imithwalo
Amandla olwakhiwo lweleli yentambo kufuneka anele ukuxhasa ubunzima obupheleleyo obungashukumiyo bazo zonke iintambo (kubandakanya ii-conductors kunye ne-insulation) kunye nayo nayiphi na imithwalo yexeshana ephilayo enokwenzeka ngexesha lokufakelwa okanye ukulungiswa (umz., ukuhamba kweenyawo zabasebenzi okanye ubunzima besixhobo). Ukukhetha kufuneka kusekelwe kumanqanaba omthwalo anikezelwe ngumvelisi, kwahlulwe phakathi kweempawu zokuthwala umthwalo wezinto ezifana nentsimbi kunye ne-aluminium alloy, ukuqinisekisa ukuba ileli ihlala izinzile ngokwesakhiwo phantsi komthwalo opheleleyo.
2. Ulawulo lweSilinganiselo sokuzaliswa kweCable
Ukuthintela umonakalo wokufakelwa kweentambo okanye ukuchithwa kakubi kobushushu okubangelwa kukuxinana kwabantu, indawo enqamlezileyo ehlala iintambo ezikwileli kufuneka ilawulwe ngokungqongqo. Iikhowudi zombane zamazwe ngamazwe (ezifana nemigangatho ye-NEC, i-IEC) zihlala zichaza ukuba indawo iyonke yeentambo ezinqamlezileyo akufuneki idlule ipesenti ethile (ngokuvamile i-40%-50%) yendawo ecacileyo yangaphakathi yeleli. Ngokubala umlinganiselo wesamba seedayamitha zentambo ukuya kwicandelo elisebenzayo leleli, ububanzi obufunekayo kunye nokuphakama kwereli esecaleni kunokufunyanwa.
3. Ukuziqhelanisa neNdawo yokuSebenza
- Iziphumo zoBushushu kunye nokuFudumala: Iindawo ezishushu kakhulu zifuna isithuba esandisiweyo seentambo okanye amacandelo eeleri ezinzulu ukuphucula ukusasazwa kobushushu; iindawo ezimanzi kufuneka zisebenzise izinto ezimelana nokugqwala ezifana nentsimbi eshushu ediphiweyo, intsimbi engagqwaliyo, okanye izinto zokugquma ezidityanisiweyo.
- Iimfuneko zoKhuseleko loMlilo: Iisekethe zokukhusela umlilo okanye kwiindawo zokuhlanganisana zikawonke-wonke zifuna iileri zekhebula ezithintela umlilo okanye ezingatshiyo, ezakhiwe ngazo kufuneka zihambelane neziqinisekiso ezifanelekileyo zokhuseleko lomlilo.
- Ukuphazamiseka kwe-Electromagnetic: Xa iintambo zamandla kunye nesignali zabelana ngeleli enye, izahlulo okanye iileli ezinamanqanaba amaninzi kufuneka zisetyenziswe ukuhlangabezana neemfuno zokuhambelana kwe-electromagnetic.
4. Ukulungiswa kweParameter yoLwakhiwo
- Umgama weerung: Umgama osondeleyo weerung (ngaphantsi kwe-150mm) ufanelekile ukuxhasa iintambo ezincinci ezinobubanzi, ngelixa umgama obanzi (ngaphezulu kwe-300mm) ungcono kwiintambo ezinzima nezinkulu. Umgama othile kufuneka ulingane nomgama omncinci wokugoba kwentambo.
- Indlela Yokuhambisa Ieledi: Khetha izinto ezifana neegoba ezithe tye, izinyusi ezithe nkqo, kunye nezinciphisi ngokusekelwe kwindlela yokufakela. Izixhobo ezingezizo ezisemgangathweni ezilungiselelwe wena zingasetyenziselwa uyilo oluntsonkothileyo.
5. Uqwalaselo lweNkqubo eNcedisayo
- Iinkqubo zoNcedo: Isithuba see-hangers kunye nee-trapeze supports kufuneka sibalwe ngokubhekiselele kwimida yokuphambuka kweleli (ngesiqhelo ≤ 1/200 yespan).
- Ukukhusela iintambo: Amanyathelo okulwa nokungcangcazela kufuneka aquke izikrufu zentambo, iziseko zokubopha, kunye nezinye izixhobo zokuthintela ukushenxa kweentambo.
- Ukugungqa: Qinisekisa ukuba umbane uyaqhubeka kulo lonke ixesha lokuqhuba, usebenzisa imitya yokubopha yobhedu okanye ii-grounding clamps ezinikezelweyo kwiindawo zokudibanisa.
6. Ilungiselelo Lokwandiswa Kwexesha Elizayo
Kucetyiswa ukuba kufakwe umda woyilo we-20%-30% ngexesha lesigaba sokucwangcisa ukuze kulungiselelwe ukwandiswa kwesekethe kwixesha elizayo. Kwiisekethe ezinokwandiswa komthamo, iileli ezinzima okanye izakhiwo ezisetyenziswa kwiimodyuli, ezinokwandiswa zinokufakelwa kwangaphambili.
Inkqubo Ecetyiswayo Yenkcazo
- Chonga iintlobo zekhebula, ububanzi bangaphandle, kunye nobunzima beeyunithi.
- Bala umthwalo uwonke uze ukhethe kuqala izinto zeleli kunye nohlobo lwesakhiwo.
- Jonga umlinganiselo wokuzalisa ukuze ubone ubungakanani obunqamlezileyo.
- Khetha inqanaba elifanelekileyo lokhuseleko ngokusekelwe kwiimpawu zokusingqongileyo.
- Yila inkqubo yenkxaso kunye nezinto ezikhethekileyo.
- Qinisekisa ukuba inkqubo iyahambelana kwaye ifikeleleka kulondolozo.
Ngokusebenzisa le ndlela yokucwangcisa ecwangcisiweyo, iimfuno zokufakela zangoku zinokufezekiswa ngelixa zihlengahlengiswa nophuhliso lwetekhnoloji yexesha elizayo, zifezekisa iindleko ezifanelekileyo zomjikelo wobomi. Kwiiprojekthi zokwenyani, kuyacetyiswa ukusebenzisa isoftware yoyilo yobungcali yokulinganisa umthwalo kunye nokufumana isiqinisekiso sobugcisa kubaboneleli.
