Zeziphi izinto eziqhelekileyo ezisetyenziselwa ukugquma iinjini

Insulating materials are materials that are non-conducting under allowable voltage, but not absolutely non-conducting materials. Under the action of a certain external electric field strength, conduction, polarization, loss, breakdown and other processes will also occur, and long-term use will also occur Ageing. The resistivity of this product is very high, usually in the range of 1010～1022Ω·m. For example, in a motor, the insulating material around the conductor isolates the turns and the grounded stator core to ensure the safe operation of the motor.

Enye: Ifilimu kunye nezixhobo ezidibeneyo zobunjineli bombane

Iipolymers ezininzi eziphezulu zemolekyuli zinokwenziwa kwiifilimu ezineempawu ezahlukeneyo kunye nokusetyenziswa. Iimpawu zeefilimu zombane zibubunzima obuncinci, ukuthamba, ukuxhathisa ukufuma, kunye namandla alungileyo ombane kunye noomatshini. Iifilimu zombane ezisetyenziswa ngokuqhelekileyo ziyifilimu ye-polyester (inqanaba E), ifilimu ye-polynaphthyl ester (inqanaba F), ifilimu ye-polyamide enuka kamnandi (inqanaba H), ifilimu ye-polyimide (inqanaba C), ifilimu ye-polytetrafluoroethylene (inqanaba H) ). Isetyenziswa kakhulu njenge-motor coil ukugquma ukugquma kunye nokugquma kwilinen ejikozayo.

2: Insulating mica kunye neemveliso zayo

Kukho iintlobo ezininzi zemica yendalo. I-mica edla ngokusetyenziswa kwi-insulation yombane ikakhulu yi-muscovite kunye ne-phlogopite. I-Muscovite ayinambala kwaye iyabonakala. I-Phlogopite isondele kwi-metallic okanye i-semi-metallic luster, kwaye eziqhelekileyo ziyigolide, zimdaka okanye ziluhlaza. I-Muscovite kunye ne-phlogopite zineempawu ezibalaseleyo zombane kunye nobushushu, ukuzinza kweekhemikhali, kunye nokuxhathisa okulungileyo kwe-corona. Iyakwazi ukuxotyulwa kwiziqwenga ezithambileyo ezinobunzima obuyi-0.01 ~ 0.03 mm. Yimathiriyeli ekrwada ebalulekileyo yokwenziwa kwezixhobo zokugquma ii-voltage eziphezulu.

I-3: Iimveliso ze-laminated

Iimveliso zemotor ezisetyenziswa ngokuqhelekileyo zenziwe ngelaphu leglasi (okanye i-mesh) efakwe kwiglue (efana ne-epoxy resin, i-silicone resin okanye i-phenolic resin) kwaye icinezelwe shushu. Phakathi kwazo, ibhodi yelaphu yeglasi ye-phenolic inamandla athile omatshini kunye neempawu zombane: kodwa inokumelana okungahambi kakuhle kwe-cleavage kunye nokumelana nokungunda ngokubanzi, okufanelekileyo ukwenza iindawo zokukhusela ngokubanzi. Ibhodi yelaphu yeglasi ye-Epoxy phenolic resin inamandla amakhulu omatshini, ukuxhathisa ukufuma, ukusebenza kombane kunye nokunganyangeki kokungunda. Ilungele iimotor ezine-voltage ephezulu njengamacandelo amangalisayo, kwaye ilungele ukusetyenziswa kwimimandla efumileyo yetropiki. Ibhodi yelaphu yeglasi ye-organic ye-silicon inokumelana nobushushu obuphezulu (ibakala le-H) kunye nokusebenza kakuhle kombane, kodwa amandla ayo omatshini angaphantsi kunalawo ebhodi yelaphu yeglasi ye-epoxy phenolic. Ilungele iindawo zokugquma ubushushu obuphezulu kwaye ifanelekile nakwiindawo ezixubeneyo ezitshisayo. Iilaminates zidla ngokusetyenziswa njengeeweji zokubeka, iigaskets zokubeka, iipads zokugquma kunye neebhodi zocingo kwiinjini ezincinci neziphakathi.
