Lefapheng la boenjiniere ba motlakase, khetho ea likhoele tse nang le matla a phahameng le a tlase ke ea bohlokoa ho netefatsa phetisetso ea matla e bolokehileng, e sebetsang hantle le e tšepahalang. Ho utloisisa phapang ea bohlokoa lipakeng tsa mefuta ena e 'meli ea likhoele ho ka thusa baenjiniere, litsebi tsa motlakase le batsamaisi ba merero ho etsa liqeto tse nepahetseng bakeng sa lits'ebetso tsa bona tse ikhethileng.
Tlhaloso le mefuta ea motlakase
Lithapo tse phahameng tsa motlakaseli etselitsoe hore li tsamaise li-voltage hangata ka holimo ho 1,000 volts (1 kV). Lithapo tsena li bohlokoa bakeng sa ho fetisa motlakase libakeng tse telele, joalo ka ho tloha lifemeng tsa motlakase ho ea liteisheneng tse nyane kapa lipakeng tsa liteishene tse nyane le marang-rang a kabo. Lisebelisoa tse tloaelehileng li kenyelletsa lithapo tsa motlakase tse holimo le litsamaiso tsa phetiso ea ka tlas'a lefatše.
Ka lehlakoreng le leng, likhoele tse nang le matla a tlase li sebetsa ka matla a tlase ho 1,000 volts. Li sebelisoa ka tloaelo ho mabone, kabo ea matla le tsamaiso ea taolo libakeng tsa bolulo, tsa khoebo le tsa indasteri. Ka mohlala, lithapo tse sebelisoang ka lithapo tsa ntlo, lipotoloho tsa mabone le mechini e nyane.
Kaho le thepa
Sebopeho sa lithapo tse nang le matla a phahameng a matla a rarahane ho feta lithapo tse nang le matla a tlase. Lithapo tse nang le matla a phahameng hangata li na le likarolo tse ngata, tse kenyelletsang li-conductors, li-insulators, lithebe le li-sheath tse ka ntle. Lisebelisoa tse sireletsang li bohlokoa ho thibela ho lutla le ho netefatsa polokeho. Lisebelisoa tse sebelisoang ka tloaelo ho lithapo tsa motlakase tse phahameng li kenyelletsa polyethylene (XLPE) e kopantsoeng le sefapano le rabara ea ethylene-propylene (EPR).
Lithapo tsa motlakase tse tlase hangata li bonolo ka moralo, leha li ntse li hloka lisebelisoa tsa boleng. Hangata li insulated ka ho sebelisa PVC (polyvinyl chloride) kapa rabara, e lekaneng bakeng sa litekanyetso tse tlaase tsa motlakase. Lisebelisoa tsa li-conductor li ka fapana, empa koporo le aluminium ke likhetho tse tloaelehileng haholo bakeng sa lisebelisoa tse phahameng le tse tlaase.
Tshebetso le tshireletso
Lithapo tse matla hahololi etselitsoe ho mamella maemo a feteletseng, ho kenyelletsa mocheso o phahameng, khatello ea mochini le maemo a tikoloho. Hangata li lekoa bakeng sa matla a dielectric, a lekanyang bokhoni ba cable ho hanela ho senyeha ha motlakase. Sena se bohlokoa ho netefatsa polokeho le ts'epahalo ea sistimi ea phetiso ea matla.
Ka lehlakoreng le leng, lithapo tsa motlakase o tlase li etselitsoe libaka tse sa hlokeng letho. Le hoja li ntse li hloka ho finyella litekanyetso tsa tšireletso, litlhoko tsa ts'ebetso ha li thata joaloka likhoele tse nang le matla a phahameng. Leha ho le joalo, lithapo tsa motlakase tse tlase li tlameha ho latela melao le melaoana ea lehae ho netefatsa ts'ebetso e bolokehileng.
Kopo
Lisebelisoa tsa lik'hebole tse nang le matla a phahameng le lithapo tsa motlakase o tlase li fapane haholo. Lithapo tse phahameng tsa motlakase li sebelisoa haholo ho fehlang matla, phetisong le lits'ebetsong tsa kabo. Li bohlokoa bakeng sa ho hokahanya mehloli ea matla a ka nchafatsoang joalo ka mapolasi a moea le a letsatsi le marang-rang.
Leha ho le joalo, lithapo tsa motlakase o tlase li fumaneha hohle bophelong ba letsatsi le letsatsi. Li sebelisoa ka lithapo tsa bolulo, mehaho ea khoebo le mehaho ea indasteri ho khantša, ho futhumatsa le ho matlafatsa lisebelisoa tse sa tšoaneng. Ho feto-fetoha ha bona ho etsa hore ba tšoanelehe bakeng sa mefuta e mengata ea likopo, ho tloha ho lipotoloho tse bonolo tsa malapa ho ea ho mekhoa e rarahaneng ea ho laola limela tsa tlhahiso.
ha re phethela
Ka kakaretso, khetho ea lithapo tse phahameng le tse tlaase li itšetlehile ka litlhoko tse khethehileng tsa tsamaiso ea motlakase e amanang le eona. Lithapo tse nang le matla a phahameng li bohlokoa bakeng sa phetiso e nepahetseng ea motlakase libakeng tse telele, athe likhoele tse nang le matla a tlase li bohlokoa bakeng sa tšebeliso ea letsatsi le letsatsi ea motlakase. Ho utloisisa liphapang tse ka sehloohong tsa kaho, ts'ebetso le ts'ebeliso ho ka thusa litsebi ho etsa liqeto tse nepahetseng ho netefatsa polokeho le ts'epahalo ea lits'ebetso tsa bona tsa motlakase. Hore na o ntse o rala marang-rang a macha a motlakase kapa likhoele tsa lapeng, ho tseba nako ea ho sebelisa likhoele tse matla haholo le tse nang le matla a tlase ho bohlokoa molemong oa katleho.
