Imininingwane Yocingo Nekhebula

Imininingwane yocingo nekhebula ibalulekile ekuqinisekiseni ukukhetha okulungile kanye nokusetshenziswa kwezintambo ezinhlelweni ezahlukene zikagesi. Nazi ezinye izici ezibalulekile zokucaciswa kwentambo nekhebula.

1. Usayizi Womqhubi
   1. Indawo ye-Cross-Sectional: Indawo ye-cross-sectional ye-conductor iyipharamitha ebalulekile, evamise ukuvezwa ngamamilimitha ayisikwele (mm²) noma ama-mil ayindilinga. Indawo enkulu ye-cross-sectional, iyancipha ukumelana kwe-conductor kanye nomthamo wokuthwala wamanje. Isibonelo, intambo kagesi yasendlini evamile ingaba nendawo ephambanayo engu-1.5 mm², 2.5 mm², noma 4 mm², kuyilapho ikhebuli yokudlulisela amandla aphezulu ingaba nendawo enkulu kakhulu ephambanayo.
   2. Ububanzi: Ububanzi bekhondakta nakho kuwukucaciswa okubalulekile, ikakhulukazi kwezinye izinhlelo zokusebenza ezikhethekile njengezintambo zamakhoaxial noma izintambo zocingo oluhle. Ububanzi be-conductor buthinta ukuguquguquka nokufaka isikhala sekhebula.
2. I-Insulation Material kanye Nokuqina
   1. I-Insulation Material: Izinto ezihlukene zokufaka ugesi zinezimo ezihlukene zokufaka ugesi, ukumelana nezinga lokushisa, nokumelana namakhemikhali. Isibonelo, ukufakwa kwe-PVC kusetshenziswa kakhulu ezintambo ezine-voltage ephansi ngenxa yezindleko eziphansi kanye nezakhiwo ezinhle zokuvala ugesi. Ukufakwa kwe-XLPE kunokumelana nezinga lokushisa okungcono kanye nezakhiwo zokuvikela ugesi, ngakho-ke kuvame ukusetshenziswa ezintanjeni zamandla kagesi aphezulu.
   2. Ukuqina kwe-Insulation: Ubukhulu besendlalelo sokufakwa kunqunywa i-voltage yokusebenza yekhebula. Uma iphezulu i-voltage yokusebenza, kudingeka ungqimba olubambayo lube lujiyile ukuze kuqinisekiswe ukuphepha kokufakwa kukagesi kwekhebula. Ngaphezu kwalokho, ukushuba kwe-insulation nakho kuthinta ukuguquguquka nobubanzi bangaphandle bekhebula.
3. I-Sheathing Material kanye Nokuqina
   1. I-Sheathing Material: Njengoba kushiwo ngaphambili, i-sheathing material isetshenziselwa ukuvikela ikhebula emonakalweni wangaphandle. Ukukhethwa kwempahla ye-sheathing kuncike endaweni yokufaka kanye nezidingo zekhebula. Isibonelo, ekufakweni kwangaphandle, i-sheathing material enokumelana okuhle kwe-UV nokusebenza okungangeni kwamanzi kuyadingeka. Ezindaweni ezinokucindezeleka okuphezulu kwemishini, i-sheathing material enamandla aqinile kanye nokumelana nomthelela kuyadingeka.
   2. Ukuqina Kwe-Sheathing: Ugqinsi longqimba lwe-sheathing nalo luyipharamitha ebalulekile, ethinta ukusebenza kokuvikela komshini kanye nempilo yesevisi yekhebula. Isendlalelo esijiyile esijiyile singanikeza ukuvikeleka okungcono kwekhebula, kodwa futhi sizokwandisa ububanzi bangaphandle nesisindo sekhebula, okungase kuthinte ukufakwa nokusetshenziswa kwentambo.
4. Isilinganiso samandla kagesi
   1. I-Voltage elinganiselwe: I-voltage elinganiselwe yekhebula yi-voltage ephezulu ikhebula engakwazi ukumelana nayo ngokuqhubekayo ngesikhathi sokusebenza okuvamile. Kuyipharamitha ebalulekile yokukhetha ikhebula. Uma i-voltage yokusebenza idlula i-voltage elinganiselwe yekhebula, ingabangela ukuphuka kwe-insulation kanye nezingozi zikagesi.
   2. I-Voltage Classification: Ngokwamazinga kagesi ahlukene, izintambo zingahlukaniswa zibe izintambo zamandla kagesi aphansi (ngaphansi kuka-1 kV), izintambo zamandla kagesi aphakathi nendawo (1 kV ukuya ku-35 kV), izintambo zamandla kagesi aphezulu (35 kV kuya ku-220 kV), kanye ne-ultra- izintambo ezinamandla kagesi (ngaphezu kuka-220 kV).
5. Ubude bekhebula
   1. Ubude obujwayelekile: Izintambo eziningi zikhiqizwa ngobude obujwayelekile, njengamamitha ayi-100, amamitha angama-500, noma amamitha ayi-1000. Ubude obujwayelekile bulungele ukukhiqizwa, ukuthutha, kanye nokufakwa. Nokho, kwamanye amaphrojekthi akhethekile, kungase kudingeke izintambo zobude obungokwezifiso.
   2. Ukubekezelela Ubude: Kukhona ukubekezelelwa kobude okuthile kwezintambo, okuvamise ukuba phakathi kwephesenti elithile lobude begama. Ukubekezelela ubude kudinga ukucatshangelwa lapho kuthengwa futhi kusetshenziswa izintambo ukuze kuqinisekiswe ukuthi ubude bangempela bekhebula buhlangabezana nezidingo zephrojekthi.
