I-coil insulation yehigh voltage motorkunomthelela omkhulu empilweni yesevisi kanye nomthelela wezomnotho we-motor, okuyinkinga ukuthi wonke umklami kanye nochwepheshe kufanele bayicabangele ngokucophelela. Ikhoyili ene-voltage ephezulu ingabizwa ngokuthi inhliziyo yenjini ngezinga elithile, okunquma ngokuqondile impilo yesevisi yemoto, kanye nokusebenza kwezinto ezivikelayo, okuyingxenye ebalulekile yekhoyili, kubalulekile.
Isakhiwo sokufakelwa kanye nenqubo yokwelapha yama-motor-voltage aphezulu emazweni ahlukahlukene ingafingqwa ngale ndlela elandelayo:
(1) I-multi-adhesive mica tape igoqwa ngokuqhubekayo, i-vacuum yomiswa, bese icindezelwa ngokushisa (ibunjiwe noma i-hydraulic).
(2) I-multi-adhesive mica tape igoqwa ngokuqhubekayo, ngaphandle kokumisa i-vacuum, futhi yakhiwe ngokuqondile ngokubunjwa okushisayo.
(3) I-mica tape enamathelayo encane igoqwa ngokuqhubekayo, i-vacuum icwiliswe kunhlaka engancibilikiyo, bese kwakhiwa ukucindezela okushisayo.
(4) I-mica tape (noma i-embryo tape emhlophe) isongwe ngokuqhubekayo, okungukuthi, umugqa uhlakazekile, bese i-resin-free resin ifakwe yonke.
Ngaphezu kwalokho, kukhona ukufakwa kwerabha ye-silicone, kanye nerabha ye-silicone kanye ne-mica tape exutshwe ukuxutshwa. Ukumelana nokushisa, ukumelana nokubanda, ukumelana nomswakama kanye nokumelana nokugqwala kwerabha ye-silicone kuhle kakhulu, kodwa ukusebenza kukagesi namandla okudabula kuncane, futhi kusetshenziselwa kuphela amamotho ane-voltage ephezulu asebenza ezindaweni ezikhethekile ezingaphansi kuka-6 kV.
Izidingo eziyisisekelo zamandla kagesi aphezului-coil insulation:
Amandla kagesi anele
Ngakolunye uhlangothi, kuyinto efiselekayo ukuthi ukufakwa kwama-motor kube mncane ngangokunokwenzeka, kodwa ngakolunye uhlangothi, kuyadingeka ukuthi kube nomkhawulo othile ngokwemibandela yamandla kagesi. Ngenxa yokuthi i-motor esebenzayo izoba ngaphansi kwe-overvoltage yomoya kanye nomthelela we-overvoltage yokusebenza: isifunda esifushane esisheshayo, izinga lokushisa kanye ne-voltage yendima yesikhathi eside, ukufakwa kwe-insulation kuzoguga kancane kancane, ukudlidliza kanye nokucindezeleka komshini kuzolimaza ukufakwa, ngaphezu kwalokho, ohlelweni lokukhiqiza ukwenza inani lokumelana nokuhlolwa kwe-voltage, ngaso sonke isikhathi, kuzokhiqiza okuthile okucashile ekuwohlokeni komphumela, ukuwohloka komphumela we-cumula. Konke lokhu kuzokwenza ukuthi amandla kagesi okufakwayo anciphe. Ngakho-ke, lapho uklama isakhiwo sekhoyili, kufanele kube nesici esithile sokuphepha.
Ukulahleka kwe-dielectric okuphansi
Ukulahlekelwa kwe-Dielectric kwenzeka lapho isakhiwo se-insulating singaphansi kwenkambu kagesi eshintshanayo. Ukulahlekelwa kwe-Dielectric ukushisa okuphakathi, nakuba kungekukhulu, kodwa kumaphuzu abuthakathaka ngamanye ekushiseni kugxilwe ikakhulukazi, uma amaphuzu abuthakathaka ekushiseni okubangelwa ukulahlekelwa kwe-dielectric ngaphezu kokushisa okukhishiwe, izinga lokushisa lendawo le-insulation lizoqhubeka nokukhuphuka, izinga lokushisa elikhulayo futhi likhuthaze ukwanda okuqhubekayo kokulahlekelwa kwe-dielectric, ukufakwa kokusebenza kwe-electromechanical kuzoba ukwehla okukhulu kobunzima bamaphuzu abuthakathaka okubangelwa ukuwohloka kwendawo kuyoba ukwehla okubukhali kobunzima bezindawo ezibuthakathaka ezibangelwa ukuphuka kwendawo. Ngakho-ke, ekulahlekeni kwe-dielectric motor ephezulu-voltage akufanele kudlule inani elishiwo.
Ukumelana kahle ne-corona
Lapho amamotho ane-voltage ephezulu esebenza, i-corona phenomenon ingenzeka ngaphakathi nangaphezulu kwendawo efakwa ngaphakathi, isheshise ukuguga nokugqwala kwe-insulation. Ngakho-ke, kumajeneretha angu-6.3kV nangaphezulu kanye namamotho angu-6kV nangaphezulu, amakhoyili awo kufanele athathe izinyathelo zokulwa ne-corona. Ikhoyili yenjini engu-6kV ayikwazi ukwelapha i-corona ngokujwayelekile, kodwa kufanele kube ukwelashwa okulwa ne-corona kumamotho asetshenziswa endaweni engeyinhle noma anamandla amakhulu.
Ukusebenza okuhle kokuguga okushisayo
Ukumelana nokushisa kwesakhiwo sokushisa okushisayo kufanele kuhlangabezane nebanga lokumelana nokushisa elidingwa umkhiqizo. Ngaphansi kwesenzo sesikhathi eside sokushisa okusebenzayo, impilo evamile yesevisi ye-insulation ingaqinisekiswa.
Ukufakwa kwezimoto kuvame ukuhlukaniswa ngo-A, E, B, F, H amamaki amahlanu okumelana nokushisa. Ngesikhathi sokusebenza, izinga lokushisa lendawo eshisa kakhulu ku-insulation ye-motor winding akumele lidlule izinga lokushisa eliphakeme elishiwo ekilasini lokufakelwa. Ngokuvamile, kuyadingeka ukushiya imajini engu-5 ~ 10 ℃. Uma isakhiwo se-insulation sakhiwe ngezinto zokuvikela zamabanga ahlukene okumelana nokushisa, izinga laso lokumelana nokushisa lingenziwa futhi lihlolwe kabanzi ngemodeli yalo yesakhiwo.
Ingakwazi ukumelana nendima yokucindezeleka kwemishini
I-insulation yekhoyili kufanele ikwazi ukumelana nenani elithile lokucindezeleka komshini ngaphandle kokuphuka noma ukubangela ukuguquguquka okuyingozi. Ikhoyili esebenzayo ngenxa yokunwetshwa kocingo kanye nokufakwa kwe-insulation akufani, ukushintsha kwezinga lokushisa, ukwahlukanisa kuzoba ngaphansi kokushuba, uma i-motor ende, kuba nomthelela omkhulu; Ngenxa yamandla kazibuthe kagesi, isiphetho sekhoyili sizophinde sikhiqize ukudlidliza, ikakhulukazi lapho injini ithintwa ukujikeleza okufushane, ukuqala kanye nokubhuleka okwamanje, amandla kazibuthe kagesi ngokuvamile abangela ukuba ikhoyili igxumeke; Ngakho-ke, i-insulation iyadingeka ukuze ibe nokunwebeka okuthile namandla emishini.
