Hona joale, e sebelisoang hangatathepa ea ho itšireletsabakeng sa likhoele tsa DC ke polyethylene. Leha ho le joalo, bafuputsi ba ntse ba batla lisebelisoa tse ling tse ka bang teng tsa ho kenya letsoho, joalo ka polypropylene (PP). Leha ho le joalo, ho sebelisa PP joalo ka thepa ea ho kenya mohala ho hlahisa mathata a 'maloa.
1. Thepa ea Mechini
Ho fihlela litlhoko tsa mantlha tsa lipalangoang, ho kenya le ts'ebetso ea likhoele tsa DC, thepa ea ho kenya letsoho e tlameha ho ba le matla a itseng a mochini, ho kenyelletsa le ho feto-fetoha ha maemo, ho lelefatsa nakong ea khefu, le ho hanyetsa mocheso o tlase. Leha ho le joalo, PP, joalo ka polymer e khanyang haholo, e bonts'a ho tiea kahare ho mocheso oa eona o sebetsang. Ho feta moo, e bonts'a bofokoli le ho ba le monyetla oa ho phatloha maemong a mocheso o tlase, ho hloleha ho fihlela maemo ana. Ka hona, lipatlisiso li tlameha ho shebana le ho tiisa le ho fetola PP ho rarolla mathata ana.
2. Ho Hanyetsa botsofali
Nakong ea ts'ebeliso ea nako e telele, ts'ebeliso ea cable ea DC butle-butle e tsofala ka lebaka la litlamorao tse kopaneng tsa matla a matla a tšimo ea motlakase le libaesekele tse futhumetseng. Botsofali bona bo lebisa ho fokotseha ha thepa ea mechine le ea ho kenya letsoho, hammoho le ho fokotseha ha matla a ho senya, qetellong ho ama ho tšepahala le bophelo ba tšebeletso ea mohala. Botsofali ba lisebelisoa tsa cable bo kenyelletsa likarolo tsa mochini, tsa motlakase, tsa mocheso le tsa lik'hemik'hale, 'me botsofali ba motlakase le mocheso ke bona bo amehang haholo. Leha ho eketsa li-antioxidants ho ka ntlafatsa khanyetso ea PP ho botsofali ba oxidative ho isa bohōleng bo itseng, tšebelisano e mpe lipakeng tsa li-antioxidants le PP, ho falla, le ho se hloeke ha tsona joalo ka litlatsetso li ama ts'ebetso ea PP. Ka hona, ho itšetleha feela ka li-antioxidants ho ntlafatsa ho hanyetsa botsofali ba PP ho ke ke ha fihlela litlhoko tsa nako ea bophelo le ts'epahalo ea ho kenya cable ea DC, ho hlokang lipatlisiso tse ling mabapi le ho fetola PP.
3. Ts'ebetso ea Insulation
Tefiso ea sebaka, e le e 'ngoe ea lintlha tse susumetsang boleng le bophelo balithapo tsa DC tse matla haholo, e ama haholo kabo ea tšimo ea motlakase ea lehae, matla a dielectric, le botsofali ba thepa ea ho kenya letsoho. Lisebelisoa tsa insulation bakeng sa likhoele tsa DC li hloka ho hatella ho bokellana ha tefiso ea sebaka, ho fokotsa ente ea litefello tsa sebaka se kang polarity, le ho sitisa tlhahiso ea litefello tsa sebaka se sa tšoaneng le polarity ho thibela ho sotheha ha lebala la motlakase ka har'a sepakapaka le li-interfaces, ho netefatsa matla a senyehileng a sa ameheng. nako ea bophelo ba cable.
Ha likhoele tsa DC li lula sebakeng sa motlakase sa unipolar ka nako e telele, lielektrone, li-ion, le ionization e sa hloekang e hlahisoang ke lisebelisoa tsa elektrode ka har'a sepakapaka e fetoha litefiso tsa sebaka. Litefiso tsena lia falla ka potlako ebe li bokellana ka har'a lipakete tsa tefiso, tse tsejoang ka hore ke pokello ea tefiso ea sebaka. Ka hona, ha u sebelisa PP ho lithapo tsa DC, ho hlokahala liphetoho ho hatella tlhahiso ea tefiso le ho bokella.
4. Thermal Conductivity
Ka lebaka la mocheso o fokolang oa mocheso, mocheso o hlahisoang nakong ea ts'ebetso ea lithapo tsa DC tse thehiloeng ho PP ha li khone ho senyeha hang-hang, e leng se bakang phapang ea mocheso pakeng tsa mahlakoreng a ka hare le a ka ntle a lera la ho kenya letsoho, ho theha sebaka se sa lekaneng sa mocheso. Motlakase oa motlakase oa thepa ea polymer o eketseha ka mocheso o ntseng o phahama. Ka hona, lehlakoreng le ka ntle la lera la ho kenya letsoho le nang le conductivity e tlaase le atisa ho bokella chelete, e leng se lebisang ho fokotseng matla a tšimo ea motlakase. Ho feta moo, li-gradients tsa mocheso li baka ente le ho falla ha palo e kholo ea litefiso tsa sebaka, ho senya le ho feta sebaka sa motlakase. Ha mocheso o ntse o eketseha, ho na le ho bokellana ha tefiso ea sebaka, ho matlafatsa ho sotha ha tšimo ea motlakase. Joalokaha ho boletsoe pejana, mocheso o phahameng, ho bokella tefiso ea sebaka, le ho sotha ha masimo a motlakase ho ama ts'ebetso e tloaelehileng le bophelo ba ts'ebeletso ea likhoele tsa DC. Kahoo, hoa hlokahala ho ntlafatsa conductivity ea mocheso oa PP ho netefatsa ts'ebetso e bolokehileng le bophelo bo bolelele ba ts'ebeletso ea likhoele tsa DC.
