Likhoeleng tsa motlakase tse mahareng le tse phahameng, metsoako ea tšireletso e tsamaisang motlakase e bapala karolo ea bohlokoa ho netefatseng kabo e ts'oanang ea tšimo ea motlakase le ho ntlafatsa sebopeho pakeng tsa mokhanni, ho kenya mocheso le likarolo tsa tšireletso. Metsoako ena hangata e etsoa ka resin ea motheo, carbon e ntšo e tsamaisang motlakase, le lisebelisoa tse fapaneng tsa ts'ebetso. Har'a likarolo tsena, resin ea motheo e na le tšusumetso e kholo ho ts'ebetsong, botsitso ba motlakase, ho lumellana ha sebopeho, ts'ebetso ea botsofali ba mocheso, le ts'epo ea nako e telele ea cable.
Lilemong tsa morao tjena, Ethylene Butyl Acrylate (EBA) e fetohile e 'ngoe ea li-resin tsa motheo tse ratoang bakeng sa metsoako ea tšireletso e tsamaisang motlakase e sebelisoang ka har'a likhoele tsa motlakase o mahareng le o phahameng, ka lebaka la ts'ebetso ea eona e leka-lekaneng hantle ka kakaretso.
Resin ea EBA ke Eng?
EBA (Ethylene Butyl Acrylate) ke copolymer ea thermoplastic e hlahisoang ho tsoa ho ethylene le butyl acrylate (BA). Ho hlahisoa ha lihlopha tsa butyl acrylate ka har'a ketane ea polymer ho fana ka polarity e itekanetseng, e lumellang EBA ho kopanya litšobotsi tse ntle tsa ts'ebetso ea polyolefin le ho lumellana ho ntlafetseng le thepa ea polar.
Ha e bapisoa le polyethylene e tloaelehileng, EBA e fana ka melemo e 'maloa:
Ho tenyetseha ho babatsehang le ho tiea ha mocheso o tlase
Botsitso bo botle ba mocheso le ho hanyetsa botsofali ba mocheso
Ho hasana ho ntlafetseng ha carbon e ntšo e tsamaisang motlakase
Ho lumellana hantle le polyethylene,XLPE, le thepa e 'ngoe ea ho thibela mocheso
Litšobotsi tsena li etsa hore EBA e be resin e khahlehang ea motheo bakeng sa metsoako e sireletsang e tsamaisang motlakase ka semi-conductive.
Hobaneng EBA e Loketse Hantle bakeng sa Metswako e Sireletsang e Semi-Conductive?
Ho Hasana ha Khabone e Ntlafetseng
Tshebetso ya motlakase ya motsoako o sireletsang o tsamaisang motlakase hanyane e itshetlehile haholo tabeng ya hore na khabone e ntšo e tsamaisang motlakase e ka etsa marangrang a tsamaisang motlakase a tshwanang le a tswelang pele.
Lihlopha tsa polar ho EBA li ntlafatsa tšebelisano lipakeng tsa resin le carbon black e tsamaisang motlakase, e leng se thusang carbon black ho hasana ka ho lekana ho pholletsa le matrix ea polymer. Ho hasana ho betere ho thusa ho fokotsa le ho tsitsisa molumo ha ka nako e ts'oanang ho ntlafatsa boleng ba bokaholimo ba lera la tšireletso, ho fokotsa liphoso tsa sebopeho le ho khothaletsa ho hokahana ho betere le lera la insulation.
Tshebetso e Tsitsitseng ea Motlakase
Nakong ea ts'ebeletso, likhoele tsa motlakase tse mahareng le tse phahameng li ba le liphetoho tse tsoelang pele tsa mocheso ha meroalo ea ts'ebetso e fetoha. Ka hona, lera la tšireletso le tsamaisang motlakase ka semi-conductive le tlameha ho boloka thepa ea motlakase e tsitsitseng ho pholletsa le mocheso o pharaletseng.
Ka mokhoa o ntlafalitsoeng, metsoako ea tšireletso ea semi-conductive e thehiloeng ho EBA e ka fana ka marang-rang a conductive a tsitsitseng haholoanyane le ho fokotsa ho feto-fetoha ha resistivity ho bakoang ke liphetoho tsa mocheso. Sena se thusa ho boloka tšimo ea motlakase e ts'oanang le ho kenya letsoho ho tšepahaleng ha cable ka nako e telele.
Khanyetso e Hlollang ea Botsofali ba Thermal
Likhoele tsa motlakase li etselitsoe ho sebetsa ka ho tsoelang pele mochesong o phahameng ka lilemo tse ngata, e leng se etsang hore ho hanyetsa botsofali ba mocheso e be thepa ea bohlokoa ea thepa ea tšireletso e tsamaisang motlakase hanyane.
Ha e bapisoa le litsamaiso tse ling tsa polymer tse tloaelehileng, EBA e fana ka botsitso bo botle ba mocheso. Kamora ho tsofala ha mocheso nako e telele, metsoako e thehiloeng ho EBA e ka boloka thepa ea eona ea mechini le botsitso ba sebopeho hamolemo, e thusang ho atolosa bophelo ba ts'ebeletso ea lera la tšireletso le sistimi ea cable ka kakaretso.
Tekanyo e Ntle ea Matla le ho Tenyetseha
Nakong eohle ea ho ntša cable, ho e kenya ka har'a thapo, ho e tsamaisa, ho e kenya le ho e sebelisa nako e telele, lera la tšireletso le tsamaisang motlakase le tlas'a khatello e fapaneng ea mechine, ho kenyeletsoa khatello, ho kobeha le potoloho ea mocheso.
Metswako ya tshireletso e thehilweng ho EBA e fana ka motswako o leka-lekaneng wa matla a mechini le ho lelefala, e fanang ka ho tenyetseha ho hoholo ha e ntse e boloka kganyetso e ntle kgahlanong le ho petsoha. Dibopeho tsena di thusa ho fihlela ditlhoko tsa tshebetso le tsa nako e telele tsa dithapo tsa motlakase tse mahareng le tse phahameng.
Bokhoni ba Nakong e Tlang Litšebelisong tsa Cable tsa HVDC
Ha theknoloji ea phetisetso ea High-Voltage Direct Current (HVDC) e ntse e tsoela pele ho ntlafala, ts'ebetso e phahameng ea hlokahala ho tsoa thepa ea tšireletso e tsamaisang motlakase ka semi-conductive.
Ntle le ho fana ka motlakase o tsitsitseng, lera la tšireletso le tsamaisang motlakase ka semi-conductive le lona le bapala karolo ea bohlokoa ho fokotseng ho kenngoa ha tjhaja ea sebaka tsamaisong ea ho kenya mocheso. Lilemong tsa morao tjena, thepa e tsamaisang motlakase ka semi-conductive e thehiloeng ho EBA e hohetse tlhokomelo e ntseng e eketseha bakeng sa lits'ebetso tsa thapo ea HVDC. Ka ntlafatso ea litsamaiso tsa resin le mekhoa ea ho tlatsa e sebetsang, metsoako e thehiloeng ho EBA e na le bokhoni ba ho ntlafatsa boits'oaro ba tjhaja ea sebaka le ho kenya letsoho litsamaisong tsa ho kenya mocheso tse tšepahalang haholoanyane bakeng sa likhoele tsa HVDC.
Lintlha tsa bohlokoa ha u sebelisa EBA
Leha EBA e fana ka melemo e mengata, thepa ea eona e lokela ho nahanoa nakong ea nts'etsopele le ts'ebetso ea tlhahiso.
Mohlala, khabone e ntšo e tsamaisang motlakase e ka monya mongobo habonolo, kahoo taolo e nepahetseng ea mongobo nakong ea polokelo, ts'ebetso le tlhahiso ea hlokahala. Ho phaella moo, EBA e bonts'a litšobotsi tse fapaneng tsa phallo ea ho qhibiliha ho tsoa ho thepa ea ho futhumatsa e thehiloeng ho polyethylene, e hlokang ntlafatso e loketseng ea maemo a ts'ebetso ea co-extrusion. Bokahare ba butyl acrylate (BA) bo boetse bo susumetsa ho tenyetseha, ho sebetsa hantle, le ho lumellana ha sebopeho, kahoo ho khetha sehlopha se loketseng sa EBA ho bohlokoa bakeng sa meaho e fapaneng ea cable le litlhoko tsa ts'ebeliso.
Qetello
Ha dikheibole tsa motlakase tse mahareng le tse phahameng, dikheibole tsa motlakase o ntjhafatswang, le ditsamaiso tsa phetiso ya HVDC di ntse di tswela pele ho fetoha, metswako ya tshireletso e tsamaisang motlakase ka semi-conductive e lebelletswe ho fana ka maemo a hodimo a botsitso ba motlakase, ho tsamaellana ha sebopeho, ho hanyetsa botsofadi ba mocheso, le tshebetso ya tshebetso.
Ka ho hasana ha eona ho hoholo ha khabone e ntšo, ts'ebetso e tsitsitseng ea motlakase, khanyetso e matla ea botsofali ba mocheso, le litšobotsi tse ikhethang tsa ts'ebetso, resin ea EBA e fetohile e 'ngoe ea li-resin tsa motheo tsa bohlokoa bakeng sa metsoako ea tšireletso e sebetsang hantle ea semi-conductive 'me ho lebelletsoe hore e tla bapala karolo ea bohlokoa haholoanyane nts'etsopele ea thepa ea cable ea moloko o latelang.
