Oiri yekudzivirira kupisa yeVarnish, inozivikanwawo sependi yekudzivirira kupisa kana varnish, ine basa guru mukudzivirira kupisa, kudzivirira hunyoro, kudzima kupisa, uye kupora mumatransformer ane frequency yakakwira.
Zvichienderana nemakemikari avo akasiyana, mafuta ekudzivirira kupisa anogona kukamurwa kuita mapoka matatu: akavakirwa papolyester; Resin class; Siliceous materials. Mafuta ekudzivirira kupisa epolyester anonyanya kugadzirwa ne condensation reaction ye polyols ne polyacids, uye kazhinji imvura isina ruvara kana yero yakajeka. Ine high breakdown voltage uye volume resistivity, iyo inogona kudzivirira current kuti isapfuure nepakati uye inopa insulation yakanaka. Ine mutengo wakanyanya pakati pemhando nhatu dzemafuta ekudzivirira kupisa uye ndiyo inonyanya kushandiswa insulation oil muma high-frequency transformers.
Zvisinei, oiri yepolyester insulating ine viscosity yakakura, uye viscosity yayo inokanganiswa zvakanyanya nekupisa. Viscosity inowedzera zvakanyanya pakupisa kwakaderera, izvo zvinokanganisa zvikuru kuyerera kwayo uye kupisa kwayo. Saka, kana ikashandiswa, inowanzo dikanwa kuwedzera diluents kuderedza viscosity yeoiri yeinsulating, kuchengetedza kuyerera kwakanaka, uye kuve nechokwadi chekuti transformer ine frequency yakakwira inogona kunyudzwa zvizere panguva yekunyudzwa. Huremu chaihwo hweoiri yepolyester insulating uye diluent inowanzo kuve inenge 0.9, iyo inogona kuyedzwa ne specific gravity meter.
Chechipiri, oiri inochengetedza polyester inogona kuoxidation uye kuora kana tembiricha yakakwira, zvichiburitsa zvinhu zvine acidic uye matope, izvo zvinokanganisa mashandiro echigadzirwa uye zvinoderedza kushandiswa kwacho munzvimbo dzinopisa zvakanyanya. Pamusoro pezvo, zvichienzaniswa nemafuta anochengetedza resin ne siliceous, mafuta anochengetedza polyester ane dielectric loss tangent values yakakwira, zvinoreva kuti kurasikirwa nesimba kwakanyanya pasi pemagetsi anochinjana uye kusvika pamwero wakati kuchakanganisa kushanda zvakanaka kwechigadzirwa.
Parizvino, mafuta ekudzivirira kupisa epolyester anoshandiswa zvakanyanya pakuisa mawindings, akadai sema transformer ane frequency high, mota, tambo, nezvimwewo, izvo zvinogona kuvandudza insulation, thermal conductivity, uye hunyoro hwezvigadzirwa uye kuwedzera hupenyu hwazvo hwekushanda. Mafuta ekudzivirira kupisa akavakirwa pa resin anonyanya kuumbwa nema organic polymer compounds, anowanzova mumvura kana kuti akaomarara, uye anodzivirira kupfeka zvakanaka.
Mafuta ekudzivirira anogadzirwa ne resin anogona kugadzirwa nekugadzirisa huwandu hwezvinhu zvakagadziriswa uye mamiriro ekuita kuti agadzire resin liquids ine viscosity yakaderera. Izvi zvinodhaka zvine fluidity yakanaka uye hunhu hwekufukidza, uye kazhinji hazvidi zvimwe zvinonyungudutsa. Kana zvichipisa, resin based insulation oil inogonawo kupfava kana kunyunguduka. Kana ichienzaniswa ne polyester insulation oil, resin insulation oil ine kugadzikana kwakanyanya, kushanda zvakanaka kwemagetsi, uye mutengo wakakwira. Inowanzoshandiswa pakudzivirira ma transformer akasiyana-siyana, ma terminal emagetsi, uye ma joints. Siliceous insulation oil inonyanya kuumbwa ne organic silicon compounds dzakadai se polydimethylsiloxane. Kazhinji imvura isina ruvara kana yero yakajeka ine viscosity yakaderera uye fluidity yakanaka.
Kana tichienzanisa nemafuta ekudzivirira kupisa epolyester neresin, mafuta ekudzivirira kupisa esilicone ane mutengo wakaderera wekurasikirwa kwe dielectric, kurasikirwa nesimba kudiki pasi pemagetsi anochinjana, uye kushanda zvakanaka kwechigadzirwa. Anewo arc resistance yakanaka uye resistance yekubuda kwemvura, uye anogona kuchengetedza kushanda kwakasimba munzvimbo dzakanyanya. Mafuta ekudzivirira kupisa esilicone anogona kushandiswa pakudzivirira kupisa munzvimbo dzakanyanya dzakadai se high voltage, high tembiricha, high humidity, uye kutonhora kwakanyanya, zvichivandudza insulation level uye kushanda kwezvigadzirwa. Nzvimbo yayo yekupisa yakanyanya uye hunhu hwekudzima moto zvinopa mafuta ekudzivirira kupisa esilicone mabhenefiti akakosha mukuchengetedza moto. Zvisinei, mafuta ekudzivirira kupisa esilicone ane mutengo wakakwira uye haawanzo shandiswa muma high-frequency transformers.
