Ndi zinthu ziti zomwe zimagwiritsidwa ntchito kwambiri pakuteteza ma mota

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.

Choyamba: Mafilimu ndi zida zophatikizika zamakina amagetsi

Ma polima angapo apamwamba amatha kupangidwa kukhala makanema okhala ndi mawonekedwe osiyanasiyana ndikugwiritsa ntchito. Makhalidwe a mafilimu amagetsi ndi makulidwe owonda, kufewa, kukana chinyezi, ndi mphamvu zabwino zamagetsi ndi makina. Mafilimu amagetsi omwe amagwiritsidwa ntchito kawirikawiri ndi filimu ya polyester (level E), filimu ya polynaphthyl ester (level F), filimu yonunkhira ya polyamide (level H), filimu ya polyimide (level C), filimu ya polytetrafluoroethylene (level H) ). Amagwiritsidwa ntchito kwambiri ngati kukulunga kwa ma coil kukulunga kwamagalimoto komanso kutsekereza kwa liner.

2: Kuteteza mica ndi zinthu zake

Pali mitundu yambiri ya mica yachilengedwe. Mica yomwe imagwiritsidwa ntchito kwambiri pakutchinjiriza magetsi ndi muscovite ndi phlogopite. Muscovite ndi yopanda mtundu komanso yowonekera. Phlogopite ili pafupi ndi zitsulo kapena semi-metal luster, ndipo zodziwika bwino ndi golide, zofiirira kapena zobiriwira. Muscovite ndi phlogopite ali ndi mphamvu zabwino kwambiri zamagetsi ndi kutentha, kukhazikika kwamankhwala, komanso kukana kwa corona. Itha kusenda mu magawo oonda osinthika okhala ndi makulidwe a 0.01 ~ 0.03 mm. Ndikofunikira kwambiri pakupangira zida zopangira ma voltage apamwamba.

3: Zopangidwa ndi laminated

Zopangidwa ndi mota zomwe zimagwiritsidwa ntchito nthawi zambiri zimapangidwa ndi nsalu zamagalasi (kapena mauna) zoviikidwa mu guluu (monga epoxy resin, silikoni utomoni kapena phenolic utomoni) ndiyeno kutentha mbanikiza. Pakati pawo, phenolic galasi nsalu bolodi ali ndi mphamvu mawotchi ndi katundu magetsi: koma ali osauka cleavage kukana ndi kukana mildew, amene ali oyenera kupanga ambiri insulating mbali. Epoxy phenolic utomoni galasi nsalu bolodi ali mkulu makina mphamvu, kukana chinyezi, ntchito magetsi ndi mildew kukana. Ndi yoyenera kwa ma motors okwera kwambiri ngati magawo odabwitsa, ndipo ndiyoyenera kugwiritsidwa ntchito kumadera otentha otentha. The organic silicon galasi nsalu bolodi ali ndi kutentha kwambiri kukana (H kalasi) ndi ntchito yabwino magetsi, koma makina mphamvu yake ndi otsika kuposa epoxy phenolic galasi nsalu bolodi. Ndi yoyenera kutenthetsa kugonjetsedwa ndi kutentha kwambiri komanso koyenera kumadera otentha osakanikirana. Ma laminates nthawi zambiri amagwiritsidwa ntchito ngati ma slot wedges, slot gaskets, ma insulating pads ndi ma wiring board muma motors ang’onoang’ono ndi apakatikati.
