Nts’etsopele ea Haufinyane ea Lisebelisoa tsa Insulating

Lisebelisoa tsa khale ka ho fetisisa tse neng li sebelisoa e ne e le lihlahisoa tsa tlhaho tse kang k’hothone, silika, mica le rabara. Mathoasong a lekholo la bo20 la lilemo, the indasteri ea maiketsetso polasetiki ea phenolic resin e qalile ho tsoa, ​​​​e nang le thepa e ntle ea motlakase le ho hanyetsa mocheso o phahameng. Hamorao, li-resin tsa urea-formaldehyde le li-alkyd resin tse nang le ts’ebetso e ntle li ile tsa hlaha ka ho latellana. Ho hlaha ha oli ea trichlorobiphenyl synthetic insulating e entse hore e tlole litšobotsing tse ikhethang tsa li-capacitor tsa matla (empa e emisitsoe kaha e kotsi bophelong ba batho). Sulfur hexafluoride le eona e ile ea etsoa ka nako eona eo.

Ho tloha lilemong tsa bo-1930, lisebelisoa tsa maiketsetso tsa insulating li tsoetse pele ka potlako, haholo-holo tse kenyelletsang resin ea acetal, neoprene, polyvinyl chloride, rabara ea styrene-butadiene, polyamide, melamine, polyethylene le polytetrafluoroethylene, e bitsoang morena oa polasetiki ka ts’ebetso e babatsehang. Ema. Ho hlaha ha lisebelisoa tsena tsa maiketsetso ho phethile karolo e kholo ho nts’etsopele ea theknoloji ea motlakase. Ka mohlala, terata ea acetal enameled e sebelisoa koloing ho ntlafatsa mocheso oa eona oa ho sebetsa le ho tšepahala, ha molumo le boima ba motlakase li fokotseha haholo. Tsoelo-pele e atlehileng ea fiber ea khalase le lebanta la eona le lohiloeng le motsoako oa resin ea silicone li ekelitse boemo ba ho hanyetsa mocheso oa sehlopha sa H ho ho kenya motlakase.

Ka mor’a lilemo tsa bo-1940, polyester e sa tsitsang le epoxy resin e ile ea tsoa. Ponahalo ea pampiri ea mica ea phofo e etsa hore batho ba tlose tlokotsi ea khaello ea lisebelisoa tsa sheet mica.

Ho tloha lilemong tsa bo-1950, lisebelisoa tse ncha tse thehiloeng holim’a li-resin tsa maiketsetso li ‘nile tsa sebelisoa haholo, tse kang polyester e sa tsitsang le li-adhesive tsa epoxy insulating bakeng sa ho kenngoa ha li-coil tsa motlakase tse phahameng. Lihlahisoa tsa letoto la polyester li sebelisoa ho kenya li-motor slot linening, terata e kentsoeng le li-varnish tse kenngoeng, ‘me ho se ho entsoe insulation ea E-class le B-low-voltage motor, e leng ho fokotsang molumo le boima ba koloi. Sulfur hexafluoride e ile ea qala ho sebelisoa lisebelisoa tsa motlakase tse nang le matla a phahameng, ‘me ea etsa hore e hole e lebisang ho miniaturization ea matla a maholo. Mohatsela oa moea oa li-circuit breakers le oli le pampiri ea li-transformer li nkeloa sebaka ke sulfur hexafluoride.

Lilemong tsa bo-1960, li-resin tse thibelang mocheso tse nang le mehele ea heterocyclic le monko o monate li ‘nile tsa ntlafatsoa haholo, tse kang polyimide, polyaramide, polyarylsulfone, polyphenylene sulfide le lisebelisoa tse ling tsa H-level le limaraka tse phahameng tse thibelang mocheso. Ho qaptjoa ha lisebelisoa tsena tse thibelang mocheso ho thehile maemo a matle bakeng sa nts’etsopele ea likoloi tsa F-class le H-class nakong e tlang. Lifilimi tsa polypropylene le tsona li ile tsa sebelisoa ka katleho ho li-capacitor tsa matla nakong ena.

Ho tloha lilemong tsa bo-1970, ho bile le liphuputso tse fokolang mabapi le nts’etsopele ea lisebelisoa tse ncha. Nakong ena, liphetoho tse fapa-fapaneng li ne li etsoa haholo-holo ho lisebelisoa tse seng li ntse li le teng ‘me sebaka sa kopo se ile sa atolosoa. Lioli tse sireletsang liminerale li hloekisoa ka mekhoa e mecha ea ho fokotsa tahlehelo ea tsona; epoxy mica insulation e entse lintlafatso tse ngata ho ntlafatseng thepa ea eona ea mochini le ho se fihlele likheo tsa moea ho ntlafatsa thepa ea eona ea motlakase. Phetoho ea li-capacitor tsa matla ho tloha mohahong o entsoeng ka pampiri-filimi ho ea ho sebopeho sa filimi e feletseng. Lithapo tsa motlakase tsa 1000 kV UHV li ile tsa qala ho ithuta ho nkela pampiri ea setso ea faeba ea tlhaho sebaka ka ho kenya pampiri ea maiketsetso. Lisebelisoa tse se nang tšilafalo tse se nang tšilafalo le tsona li ntlafalitse ka potlako ho tloha lilemong tsa bo-1970, joalo ka tšebeliso ea li-isopropyl biphenyl tse mahareng tse se nang chefo le oli ea ester ho nkela sebaka se chefo sa chlorinated biphenyl, le katoloso ea pente e senang solvent. Ka ho tsebahala ha lisebelisoa tsa ntlo, likotsi tse kholo tsa mollo li atisa ho etsahala ka lebaka la mollo oa thepa ea bona ea ho itšireletsa, kahoo lipatlisiso tsa lisebelisoa tse thibelang lelakabe li khahlile tlhokomelo.
