In the field of electrical engineering, the selection of high-voltage and low-voltage cables is crucial to ensure safe, efficient and reliable power transmission. Ho utloisisa phapang ea bohlokoa lipakeng tsa mefuta ena e 'meli ea lienjineri ho ka thusa lienjiniere, li-electric le batsamaisi ba merero ba etsa liqeto tse hlokofalitsoeng bakeng sa lits'ebetso tse khethehileng.
Tlhaloso le bophahamo ba voltage
Likhoele tse phahameng tsa voltageli etselitsoe ho jara lintlafatso tsa hona joale ka har'a volts tse 1 000 (1 kv). Likhoele tsena li bohlokoa bakeng sa ho fetisa motlakase ka lebaka la maeto a se malelele, joalo ka limela tsa matla ho ea linthong kapa lipakeng tsa li-curtations tsa matla. Litlhophiso tse tloaelehileng li kenyelletsa makhasi a motlakase a holimo le lits'ebeletso tsa phetisetsoang ka tlasa lefatše.
Ka lehlakoreng le leng likhoele tse tlase tsa voltage tse tlase li sebetsa ka linōpo tse ka tlase ho Volts tse 1 000. Hangata li sebelisoa ka mabone, litšusumetso tsa motlakase le lits'ebetso tsa taolo sebakeng sa bolulo, khoebong le indasteri. Mohlala, likhoele tse sebelisoang ka tlung, lipotoloho tse mabone le mochini o monyane.
Kaho le lisebelisoa
Sebopeho sa likhoele tse phahameng tsa voltage li rarahane ho feta tsa likhoele tse tlase tsa voltage. Likhoele tse phahameng tsa voltage hangata li na le likarolo tse ngata, ho kenyelletsa bapalamisi, lihlahla le liqhobosheane tsa ka ntle. Lisebelisoa tsa ho hlahloba li bohlokoa ho thibela ho tsoa le ho netefatsa polokeho. Lisebelisoa tse tloaelehileng tsa Insulation ka lichineng tse phahameng li kenyelletsa polyethylene le amanang le polyethylene le Ethylene-profinse ea ething.
Likotlo tse tlase tsa voltage ka kakaretso li bonolo li entsoe ka moralo, leha li ntse li hloka lisebelisoa tsa boleng. Hangata li angoa ka ho sebelisa PVC (Polyvinyl chloride) kapa rabara, e lekaneng liphetho tse tlase tsa voltage. Lisebelisoa tsa mokhanni oa mokhanni li ka fapana, empa koporo le aluminium ke liqeto tse atileng haholo bakeng sa lits'ebetso tse phahameng haholo le tse tlaase.
Ts'ebetso le polokeho
Likopo tse phahameng tsa voltageba enjene ho mamella maemo a feteletseng, ho kenyelletsa le lithemparetjha tse phahameng, khatello ea maikutlo le mabaka a tikoloho. Hangata ba lekoa ba matla a Diabolose, a lekanyang bokhoni ba cable ba ho hanela tlhekefetso ea elektrori. Sena se bohlokoa ho netefatsa polokeho le ho ts'epahala ha phetisetso ea motlakase oa matla.
Ho fapana le hoo, likhoele tse tlase tsa voltage tse tlase li etselitsoe libaka tse sa hlokahaleng tse batlang. Ha ba ntse ba hloka ho kopana le litekanyetso tsa polokeho, litlhokahalo tsa ts'ebetso ha li loanele likhoele tse ngata tsa voltage. Leha ho le joalo, likhoele tse tlaase tsa voltage li ntse li tlameha ho latela likhoutu tsa mantlha tsa lehae le melaoana ea lehae ho netefatsa ts'ebetso e bolokehileng.
Kopo
Likopo tsa likhoele tse phahameng tsa voltage tse phahameng le likhopo tse tlase tsa voltage li fapane haholo. Likhomo tse phahameng tsa voltage li sebelisoa haholo molokong oa matla, phetiso le tsamaiso ea kabo. Ba bohlokoa bakeng sa ho tlosa mehloli ea matla e nchafalitsoeng e kang moea le mapolasi a letsatsi ho grid.
Leha ho le joalo, likhoele tsa voltage tse tlase li se li le boima bophelong ba letsatsi le letsatsi. Li sebelisoa meahong ea bolulo, meaho ea khoebo le meaho le matla le matla a lisebelisoa tse fapaneng. Ho fokola ha bona ho etsa hore ba tšoane le likopo tse fapaneng tsa likopo, ho tloha ho lipotoloho tse bonolo tsa malapa ho ea ho litsamaiso tse thata tsa taolo limela tsa tlhahiso.
ha re phethela
Ka kakaretso, khetho ea lintlha tse phahameng le lichineng tsa voltage tse tlase li itšetlehile ka litlhoko tse ikhethileng tsa sistimi e amanang le motlakase. Likhoele tse phahameng tsa voltage li bohlokoa bakeng sa phetisetso e sebetsang ea motlakase ka nako e telele, ha likhoele tse tlase tsa voltage li bohlokoa bakeng sa lits'ebeliso tsa motlakase oa letsatsi le letsatsi. Ho utloisisa liphapang tsa bohlokoa ka ho haha, ho etsa tšebetso le kopo ho ka thusa litsebo ho etsa liqeto tse babiselitsoeng ho netefatsa polokeho le ts'ehetso ea tsamaiso ea bona ea makala. Hore na u rala grid ea motlakase kapa ea hau ea ho tseba hore na o tla sebelisa lithaele tse phahameng le tse tlase ho bohlokoa ho atleha.
