Ke lisebelisoa life tse sebelisoang hangata bakeng sa li-motor

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.

E ‘ngoe: Filimi le lisebelisoa tse kopaneng tsa boenjiniere ba motlakase

Li-polymers tse ngata tse phahameng tsa limolek’hule li ka etsoa lifilimi tse nang le litšobotsi le ts’ebeliso e fapaneng. Litšobotsi tsa lifilimi tsa motlakase ke botenya bo tšesaane, bonolo, ho hanyetsa mongobo, le matla a matle a motlakase le a mechine. Lifilimi tsa motlakase tse sebelisoang ka tloaelo ke filimi ea polyester (boemo ba E), filimi ea polynaphthyl ester (boemo ba F), filimi e nkhang hamonate ea polyamide (boemo ba H), filimi ea polyimide (boemo ba C), filimi ea polytetrafluoroethylene (boemo ba H) ). Haholo-holo e sebelisoa e le sekoaelo sa ho phuthela ha li-motor coil le sekontiri sa liner.

2: Insulating mica le lihlahisoa tsa eona

Ho na le mefuta e mengata ea mica ea tlhaho. Mica e atisang ho sebelisoa ha ho kenngoa motlakase ke haholo-holo muscovite le phlogopite. Muscovite ha e na ‘mala ebile e pepenene. Phlogopite e haufi le metallic kapa semi-metallic luster, ‘me tse tloaelehileng ke khauta, sootho kapa botala bo khanyang. Muscovite le phlogopite li na le thepa e ntle ea ho hanyetsa motlakase le mocheso, botsitso ba lik’hemik’hale, le ho hanyetsa corona hantle. E ka ebolloa ka lilae tse tšesaane tse tenyetsehang tse nang le botenya ba 0.01 ~ 0.03 mm. Ke thepa e tala ea bohlokoa bakeng sa ho etsoa ha lisebelisoa tse phahameng tsa motlakase.

3: Lihlahisoa tsa laminated

Lihlahisoa tsa laminated tse sebelisoang hangata li entsoe ka lesela la khalase (kapa letlooeng) le kenngoeng ka sekhomaretsing (joalo ka epoxy resin, silicone resin kapa phenolic resin) ebe e hatelloa ka ho chesa. Har’a bona, boto ea lesela la khalase ea phenolic e na le matla a itseng a mochine le thepa ea motlakase: empa e na le khanyetso e fokolang ea cleavage le ho hanyetsa hlobo ka kakaretso, e loketseng ho etsa likarolo tse tloaelehileng tsa insulating. Epoxy phenolic resin glass cloth board e na le matla a phahameng a mochine, ho hanyetsa mongobo, ts’ebetso ea motlakase le ho hanyetsa hlobo. E loketse li-motor tse nang le matla a phahameng joalo ka likarolo tse makatsang, ‘me e loketse ho sebelisoa libakeng tse mongobo tsa tropike. Boto ea lesela la khalase ea silicon e na le mocheso o phahameng oa mocheso (H grade) le ts’ebetso e ntle ea motlakase, empa matla a eona a mochine a tlase ho feta a epoxy phenolic glass cloth board. E loketse likarolo tse phahameng tsa mocheso tse thibelang mocheso hape e loketse libaka tse tsoakiloeng tsa tropike. Hangata li-laminate li sebelisoa e le li-slot wedges, slot gaskets, li-pads tse sireletsang le liboto tsa likhoele ka li-motor tse nyane le tse mahareng.
