Yiziphi izinto ezivame ukusetshenziswa zokuvikela ama-motors
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.
Okokuqala: Ifilimu nezinto eziyinhlanganisela zobunjiniyela bukagesi
Ama-polymers amaningi aphezulu angenziwa abe amafilimu anezici ezihlukene kanye nokusetshenziswa. Izici zamafilimu kagesi ukuqina okuncane, ukuthambile, ukumelana nomswakama, namandla amahle kagesi kanye nemishini. Amafilimu kagesi asetshenziswa kakhulu ifilimu ye-polyester (izinga E), ifilimu ye-polynaphthyl ester (izinga F), ifilimu ye-polyamide enuka kamnandi (izinga H), ifilimu ye-polyimide (izinga C), ifilimu ye-polytetrafluoroethylene (izinga H) ). Isetshenziswa kakhulu njenge-motor coil wrapping insulation kanye nokufakwa kwama-winding liner.
2: I-insulating mica nemikhiqizo yayo
Kunezinhlobo eziningi zemica yemvelo. I-mica evame ukusetshenziswa ekufakeni ugesi ikakhulukazi i-muscovite ne-phlogopite. I-Muscovite ayinambala futhi isobala. I-phlogopite iseduze nokucwebezela kwe-metallic noma i-semi-metallic, kanti ezivamile ziyigolide, insundu noma eluhlaza ngokukhanyayo. I-Muscovite ne-phlogopite inezindawo ezinhle kakhulu zokumelana nogesi nokushisa, ukuqina kwamakhemikhali, nokumelana okuhle kwe-corona. Ingahlutshwa ibe yizicucu ezizacile eziguquguqukayo ezinogqinsi luka-0.01~0.03 mm. Kuyimpahla ebalulekile yokwenziwa kwezinto ezifakwa ku-voltage ephezulu.
3: Imikhiqizo eyenziwe nge-laminated
Imikhiqizo evame ukusetshenziswa ezimotweni yenziwe ngendwangu yengilazi (noma inezikhala) efakwe kuglue (njenge-epoxy resin, i-silicone resin noma i-phenolic resin) bese icindezelwe ngokushisa. Phakathi kwazo, ibhodi lendwangu yengilazi ye-phenolic inamandla athile omshini kanye nezakhiwo zikagesi: kodwa inokumelana okubuthakathaka kwe-cleavage kanye nokumelana nokukhunta okujwayelekile, okulungele ukwenza izingxenye ezijwayelekile zokuvikela. Ibhodi lendwangu yengilazi ye-epoxy phenolic resin inamandla aphezulu emishini, ukumelana nomswakama, ukusebenza kukagesi kanye nokumelana nesikhutha. Ilungele ama-motor-voltage aphezulu njengezingxenye ezimangalisayo, futhi ifanele ukusetshenziswa ezindaweni ezinomswakama oshisayo. Ibhodi lendwangu yengilazi ye-silicon yengilazi inokumelana nokushisa okuphezulu (ibanga H) kanye nokusebenza kahle kukagesi, kodwa amandla ayo okusebenza aphansi kunalawo ebhodi lendwangu yengilazi ye-epoxy phenolic. Ilungele izingxenye zokuvikela ukumelana nokushisa okuphezulu futhi ifanele izindawo ezixubile ezishisayo. Ama-laminates avame ukusetshenziswa njengama-slot wedge, ama-slot gaskets, ama-insulating pads namabhodi okufaka izintambo kumamotho amancane naphakathi.
