1.Indima yokudipha upende

1. Thuthukisa umsebenzi wokuvikela umswakama wama-motor windings.

Ekujikeni, kunezimbotshana eziningi ku-slot insulation, i-interlayer insulation, ukufakwa kwesigaba, izintambo ezibophayo, njll.Kulula ukumunca umswakama emoyeni futhi kunciphise ukusebenza kwawo kokufakelwa. Ngemva kokucwiliswa nokomiswa, i-motor igcwaliswa ngopende ovikelayo bese yenza ifilimu kapende elibushelelezi, okwenza kube nzima ukuthi umswakama namagesi agqwalayo ahlasele, ngaleyo ndlela kuthuthukiswe izakhiwo zokuzungeza umswakama nezimelana nokugqwala.

2.Thuthukisa amandla okufaka ugesi okusonga.

Ngemuva kokuthi ama-winding acwiliswe ngopende futhi omisiwe, ukuphenduka kwawo, amakhoyili, izigaba kanye nezinto ezihlukahlukene zokuvikela zigcwele upende ovikelayo onezici ezinhle ze-dielectric, okwenza amandla okugxilisa ama-winding aphezulu kakhulu kunangaphambi kokucwiliswa ngopende.

3.Izimo ezithuthukisiwe zokulahla ukushisa kanye nokuqhutshwa kwe-thermal okuthuthukisiwe.

Ukukhuphuka kwezinga lokushisa kwemoto ngesikhathi sokusebenza isikhathi eside kuthinta ngqo impilo yayo yenkonzo. Ukushisa kwe-winding kudluliselwa kusinki yokushisa ngokusebenzisa i-slot insulation. Izikhala ezinkulu phakathi kwephepha le-insulation wire ngaphambi kwe-varnish azihambisani nokuqhutshwa kokushisa ekujikeni. Ngemuva kokugcoba nokumisa, lezi zikhala zigcwaliswa nge-varnish evikelayo. I-conductivity eshisayo ye-varnish e-insulating ingcono kakhulu kunomoya, ngaleyo ndlela ithuthukise kakhulu izimo zokushisa ukushisa kwe-winding.

2.Izinhlobo ze-varnish evikelayo

Kunezinhlobo eziningi zopende ovikelayo,Ofana ne-epoxy polyester, i-polyurethane, ne-polyimide.Ngokujwayelekile, upende wokuvikela ohambelanayo ukhethwa ngokwezinga lokumelana nokushisa, njenge-162 epoxy ester koqweqwe lwawo olubomvu ebangeni B (130 degrees) 9129 epoxy-free topcoat-free topcoat F (155 degrees 0, polyesterified U197 degrees high), polyesterified U197 degrees high, polyesterified U197 degrees isimo sokuthi upende we-insulating uhlangabezana nemfuneko yokumelana nokushisa, kufanele kukhethwe ngokuvumelana nendawo lapho injini ikhona khona, njenge-thermal conductivity, ukumelana nomswakama, njll.

3.Izinhlobo ezinhlanu zezinqubo zokuvanisha

1.Ukuthulula

Lapho ulungisa i-motor eyodwa, i-varnishing evunguzayo ingenziwa ngenqubo yokuthulula.Lapho uthela, beka i-stator ngokuqondile phezu kwe-tray yokudonsa upende enomkhawulo owodwa wokugoqa ubheke phezulu, futhi usebenzise ibhodwe lokupenda noma ibhulashi lokupenda ukuze uthele upende engxenyeni engenhla ye-winding. ithululiwe ngokugcwele.

2.I-drip leaching

Le ndlela ifaneleka ukuvenisha kwamamotho kagesi amancane naphakathi nendawo.

①Ifomula. I-6101 epoxy resin (isilinganiso sobuningi), i-50% ye-tung oil maleic anhydride, isilungele ukusetshenziswa.

②Ukushisa ngaphambi kwesikhathi: Shisisa ukusonga cishe imizuzu emi-4, bese ulawula izinga lokushisa eliphakathi kuka-100 no-115°C (okukalwa ngethemometha yendawo), noma ubeke okokusonga esithandweni esomisayo bese usishisa cishe amahora angu-0.5.

③Ukuconsa. Beka i-motor stator mpo ethreyini kapende, bese uqala ukuconsa upende ngesandla lapho izinga lokushisa lemoto lehla liye ku-60-70℃. Ngemuva kwemizuzu eyi-10, vula i-stator bese uconsa upende ngakolunye uhlangothi lwesiphetho kuze kube yilapho usucwiliswe kahle.

④Ukwelapha. Ngemuva kokudonsa, ukuvuthwa kunikezwa amandla okuphulukisa, futhi izinga lokushisa elijikayo ligcinwa ku-100-150 ° C; inani lokumelana nokufakwa kukalwa lize lifaneleke (20MΩ), noma ukusonga kufakwe esithandweni sokumisa ukuze kushiswe ezingeni lokushisa elifanayo cishe amahora ama-2 (kuye ngokuthi ubukhulu bemoto), futhi ikhishwa kuhhavini lapho ukumelana nokushisa kudlula i-1.5MΩ.

3.Roller upende

Le ndlela ifanele ukuvarnishing kwamamotho aphakathi nendawo. Uma ugoqa upende, uthele upende ovikelayo ethangini likapende, beka i-rotor ethangini lopende, futhi indawo yopende kufanele icwilise i-rotor winding ngaphezu kuka-200mm. Uma ithangi likapende lingashoni kakhulu futhi indawo ye-rotor winding ecwiliswe kupende incane, i-rotor kufanele igoqwe izikhathi eziningana, noma upende kufanele usetshenziswe ngebhulashi ngenkathi i-rotor igoqwe. Ngokuvamile ukugoqa izikhathi ezi-3 kuya kwezi-5 kungenza upende ovikelayo ungene endaweni yokufakwa ngaphakathi.

4.Ukucwiliswa emanzini

Lapho ulungisa ama-motor amancane naphakathi ngamaqoqo, ama-windings angacwiliswa ngopende. Uma ucwilisa, qala ngokufaka inani elifanele likapende wokuvikela upende ekanini likapende, bese ulengisa i-motor stator, ukuze uketshezi lukapende lucwilise i-stator ngaphezu kuka-200mm. Lapho uketshezi lwepende lungena kuzo zonke izikhala phakathi kwama-windings kanye nephepha le-insulating, i-stator iphakanyiswe phezulu futhi upende uphonswa. Uma ingcindezi engu-0.3 ~ 0.5MPa yengezwa ngesikhathi sokucwiliswa, umphumela uzoba ngcono.

5.Ukucwiliswa kwengcindezi ye-vacuum

Ama-windinging ama-high-voltage motors kanye nama-motor amancane naphakathi anezidingo zekhwalithi ephezulu yokufakelwa angafakwa ngaphansi kwe-vacuum pressure dipping. Ngesikhathi sokucwiliswa, i-stator ye-motor ifakwa esitsheni sopende esivaliwe futhi umswakama uyasuswa kusetshenziswa ubuchwepheshe be-vacuum. Ngemuva kokuthi ama-winding acwiliswe ngopende, ingcindezi ye-200 kuya ku-700 kPa isetshenziswa endaweni kapende ukuvumela uketshezi lwepende ukuthi lungene kuzo zonke izikhala kuma-windings futhi lujule ezimbotsheni zephepha lokuvikela ukuze kuqinisekiswe ikhwalithi yokucwiliswa.
