Ukufakwa kwe-coil kwe-insulationimoto enamandla aphezuluinempembelelo enkulu kubomi benkonzo kunye nefuthe lezoqoqosho lemoto, nto leyo emele iqwalaselwe ngononophelo ngumyili kunye nochwephesha. Ikhoyili ye-high-voltage ingabizwa ngokuba yintliziyo yemoto ukuya kuthi ga kwinqanaba elithile, nto leyo emisela ngokuthe ngqo ubomi benkonzo yemoto, kwaye ukusebenza kwezinto zokukhusela, eziyinxalenye ebalulekileyo yekhoyili, kubalulekile.
Ulwakhiwo lwe-insulation kunye nenkqubo yonyango lwee-motors ezine-voltage ephezulu kumazwe ahlukeneyo zinokushwankathelwa ngolu hlobo lulandelayo:
(1) Iteyiphu ye-mica enamathelayo emininzi isoloko isongwa, yomiswe nge-vacuum, ize emva koko icinezelwe ngobushushu (ibunjwe okanye yenziwe nge-hydraulic).
(2) Iteyiphu ye-mica enamathelayo emininzi isoloko isongwa, ngaphandle kokomiswa nge-vacuum, kwaye yenziwe ngokuthe ngqo ngokubumba okushushu.
(3) Iteyiphu ye-mica enamathelayo encinci isoloko isongwa, ifakwa kwi-vacuum kwi-resin engenasombululo, ize emva koko icinezelwe ngobushushu.
(4) Iteyiphu ye-mica (okanye iteyiphu emhlophe ye-embryo) isoloko isongwa, oko kukuthi, umgca uyasasazeka, ize emva koko i-resin engenasombululo ifunxwe iyonke.
Ukongeza, kukho i-silicone rubber insulation, kunye ne-silicone rubber kunye ne-mica tape mixed insulation. Ukumelana nobushushu, ukumelana nokubanda, ukumelana nokufuma kunye nokumelana nokugqwala kwe-silicone rubber zilungile kakhulu, kodwa ukusebenza kombane kunye namandla okukrazula aphantsi, kwaye isetyenziselwa kuphela iimoto ezine-high-voltage ezisebenza kwiindawo ezikhethekileyo ezingaphantsi kwe-6 kV.
Iimfuno ezisisiseko zombane ophezuluubushushu bekhoyili:
Umbane owaneleyo
Kwelinye icala, kuyanqweneleka ukuba ubushushu beemoto bube buncinci kangangoko kunokwenzeka, kodwa kwelinye icala, kufuneka ukuba kubekho umda othile ngokwamandla ombane. Ngenxa yokuba imoto esebenza, iya kuba phantsi koxinzelelo oluphezulu lomoya kunye nempembelelo yoxinzelelo oluphezulu lokusebenza: umjikelo omfutshane ngequbuliso, ubushushu kunye nobushushu bendima yexesha elide, ubushushu buya kuguga kancinci kancinci, ukungcangcazela kunye noxinzelelo loomatshini kuya konakalisa ubushushu, ukongeza, kwinkqubo yokuvelisa ukwenza uvavanyo oluninzi lokumelana nobushushu, ngalo lonke ixesha, kuya kuvelisa imikhondo ethile yokuwohloka okuncinci kwesakhiwo sobushushu, oko kukuthi, isiphumo esibizwa ngokuba yi-cumulative effect. Zonke ezi zinto ziya kwenza amandla ombane obushushu ehle. Ke ngoko, xa kuyilwa isakhiwo se-coil, kufuneka kubekho into ethile yokhuseleko.
Ukulahleka okuphantsi kwe-dielectric
Ukulahleka kweDielectric kwenzeka xa isakhiwo sokukhusela siphantsi komhlaba wombane otshintshisanayo. Ukulahleka kweDielectric kobushushu obuqhelekileyo, nangona bungabukhulu, kodwa kwiindawo ezibuthathaka ngabanye kubushushu kugxininiswe ngakumbi, ukuba iindawo ezibuthathaka kubushushu obubangelwa kukulahleka kweDielectric zingaphezulu kunobushushu obukhutshiweyo, ubushushu bendawo bokukhusela buya kuqhubeka bunyuka, ubushushu obukhulayo bukhuthaze ukunyuka ngakumbi kokulahleka kweDielectric, ukufudumala kokusebenza kwe-electromechanical kuya kuba kukwehla okukhulu kobunzima bamanqaku abuthathaka okuphazamiseka kobushushu bendawo kuya kubangelwa. Ke ngoko, kwi-high-voltage motor ilahleko ye-dielectric akufuneki idlule ixabiso elichaziweyo.
Ukumelana kakuhle ne-corona
Xa iimoto ezine-voltage ephezulu zisebenza, isiganeko se-corona sinokwenzeka ngaphakathi nakumphezulu we-insulation, nto leyo ekhawulezisa ukuguga nokugqwala kwe-insulation. Ke ngoko, kwiijenereyitha ze-6.3kV nangaphezulu kunye neemoto ze-6kV nangaphezulu, iikhoyili zazo kufuneka zithathe amanyathelo okulwa ne-corona. Ikhoyili yemoto ye-6kV ayinakuba yinyango lokulwa ne-corona ngokubanzi, kodwa kufuneka ibe yinyango lokulwa ne-corona kwiimoto ezisetyenziswa kwindawo embi okanye ezinomthamo omkhulu.
Ukusebenza kakuhle kokuguga kobushushu
Ukumelana nobushushu kwesakhiwo sokukhusela ubushushu kufuneka kuhlangabezane nomgangatho wokumelana nobushushu ofunekayo yimveliso. Phantsi kwesenzo sexesha elide sobushushu bokusebenza, ubomi benkonzo eqhelekileyo yokukhusela bunokuqinisekiswa.
Ubushushu bemoto buhlala buhlulwe bube zii-A, E, B, F, H ezintlanu. Ngexesha lokusebenza, ubushushu bendawo eshushu kakhulu kwi-insulation ye-motor winding akumele budlule ubushushu obuphezulu obuchazwe kwi-insulation class. Ngokubanzi, kuyimfuneko ukushiya umda we-5 ~ 10℃. Ukuba isakhiwo se-insulation senziwe ngezinto zobushushu zamanqanaba ahlukeneyo okumelana nobushushu, umgangatho waso wokumelana nobushushu unokulinganiswa kwaye uvavanywe ngokupheleleyo ngemodeli yaso yokwakha.
Iyakwazi ukumelana nendima yoxinzelelo loomatshini
Ukufakwa kwe-insulation ye-coil kufuneka ikwazi ukumelana noxinzelelo oluthile loomatshini ngaphandle kokuphuka okanye ukubangela ukuguquka okuyingozi. I-coil esebenzayo ngenxa yokwanda kwe-coefficient ye-wire kunye ne-insulation ayifani, utshintsho lobushushu, ukufakelwa kwe-insulation kuya kuba phantsi koxinzelelo, okukhona imoto ide, kokukhona impembelelo inkulu; Ngenxa yamandla e-electromagnetic, isiphelo se-coil siya kuvelisa ukungcangcazela, ngakumbi xa imoto ichatshazelwa yi-short circuit, ukuqala kunye nombane we-braking, amandla e-electromagnetic adla ngokubangela ukuba i-coil iguqulwe; Ke ngoko, ukufakelwa kwe-insulation kuyadingeka ukuze ibe nokuqina okuthile kunye namandla e-mechanical.
