Ndeapi anowanzo shandiswa insulating zvinhu zvemotor

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.

Imwe: Firimu uye zvinhu zvinosanganiswa zveinjiniya yemagetsi

Mapolymer akati wandei anogona kugadzirwa kuita mafirimu ane hunhu hwakasiyana uye mashandisiro. Hunhu hwemafirimu emagetsi hutete hwakakora, hunyoro, hunyoro hunodzivirira, uye simba rakanaka remagetsi nemakanika. Mafirimu emagetsi anowanzo shandiswa ipolyester film (level E), polynaphthyl ester film (level F), anonhuwirira polyamide film (level H), polyimide film (level C), polytetrafluoroethylene film (level H) ). Inonyanya kushandiswa semotor coil yekuputira insulation uye winding liner insulation.

2: Insulating mica uye zvigadzirwa zvayo

Kune akawanda marudzi echisikigo mica. Iyo mica inowanzoshandiswa mukudzivirira kwemagetsi inonyanya kushandiswa muscovite uye phlogopite. Muscovite haina ruvara uye yakajeka. Phlogopite iri padyo nesimbi kana semi-metallic kupenya, uye zvakajairika igoridhe, shava kana girinhi rakareruka. Muscovite uye phlogopite vane yakanakisa magetsi uye kupisa kudzivirira zvivakwa, kugadzikana kwemakemikari, uye yakanaka corona kuramba. Inogona kupepetwa kuita zvidimbu zvitete zvinochinjika zvine ukobvu hwe 0.01 ~ 0.03 mm. Icho chinhu chakakosha mbishi yekugadzira yakakwirira-voltage insulation zvinhu.

3: Laminated zvigadzirwa

Motokari dzinowanzo shandiswa laminate zvigadzirwa zvinogadzirwa nejira regirazi (kana mesh) rakanyikwa muglue (senge epoxy resin, silicone resin kana phenolic resin) yobva yapisa yakadzvanywa. Pakati pazvo, phenolic girazi rejira bhodhi rine mamwe emagetsi simba uye zvemagetsi zvivakwa: asi ine kushomeka kwe cleavage resistance uye general mildew resistance, iyo inokodzera kugadzira general insulating parts. Epoxy phenolic resin girazi jira bhodhi rine yakakwirira mechanical simba, mwando kuramba, magetsi kuita uye mildew kuramba. Inokodzera ma-high-voltage motors sezvikamu zvinokatyamadza, uye inokodzera kushandiswa munzvimbo dzine hunyoro dzinopisa. Iyo organic silicon girazi jira bhodhi ine yakanyanya kupisa kupisa (H giredhi) uye yakanaka kushanda kwemagetsi, asi simba rayo remuchina rakaderera pane iro epoxy phenolic girazi rejira bhodhi. Yakakodzera kune yakakwira tembiricha inodzivirira kudzivirira zvikamu uye zvakare yakakodzera kune dzakasanganiswa nzvimbo dzinopisa. Laminates anowanzo shandiswa se slot wedges, slot gaskets, insulating pads uye wiring board mumadiki uye epakati-saizi mota.
