Ukufakwa kwekhoyili yeamandla ombane aphezuluinempembelelo enkulu kubomi benkonzo kunye nefuthe loqoqosho lwemoto, okuyingxaki ukuba wonke umyili kunye nochwephesha kufuneka baqwalasele ngokucophelela. I-coil ye-high-voltage ingabizwa ngokuba yintliziyo ye-motor ukuya kwinqanaba elithile, elichaza ngokuthe ngqo ubomi benkonzo yemoto, kunye nokusebenza kwezinto ezikhuselayo, eyona nxalenye ebalulekileyo yekhoyili, ibalulekile.
Ubume be-insulation kunye nenkqubo yonyango yee-motor high-voltage kumazwe ahlukeneyo inokushwankathelwa ngolu hlobo lulandelayo:
(1) I-Multi-adhesive mica tape igqunywe ngokuqhubekayo, i-vacuum yomisiwe, kwaye emva koko icinezele ishushu (i-moulded okanye i-hydraulic).
(2) I-multi-adhesive mica tape ihlanganiswe ngokuqhubekayo, ngaphandle kokumisa i-vacuum, kwaye yenziwe ngokuthe ngqo ngokubumba okutshisayo.
(3) I-tape ye-mica encamathelayo encinci isongiwe ngokuqhubekayo, i-vacuum intywiliselwe kwi-solventless resin, kwaye emva koko i-hot press yenza.
(4) I-mica tape (okanye i-embryo tape emhlophe) ihlanganiswe ngokuqhubekayo, oko kukuthi, umgca uhlakazekile, kwaye ke i-resin-free resin ifakwe ngokupheleleyo.
Ukongeza, kukho ukugqunywa kwerubha ye-silicone, kunye nerubha ye-silicone kunye ne-mica tape exutywe ukugquma. Ukumelana nobushushu, ukumelana nokubanda, ukuxhathisa ukufuma kunye nokumelana nokugqwala kwerabha ye-silicone kugqwesileyo, kodwa ukusebenza kombane kunye namandla okukrazula akulunganga, kwaye isetyenziselwa kuphela ii-motor-high-voltage ezisebenza kwindawo ezizodwa ezingaphantsi kwe-6 kV.
Iimfuno ezisisiseko zombane ophezuluukugquma ikhoyili:
Amandla awoneleyo ombane
Ngakolunye uhlangothi, kuyinqweneleka ukuba i-insulation of motors ibe yincinci ngokusemandleni, kodwa ngakolunye uhlangothi, kufuneka ibe nomda othile ngokubhekiselele kumandla ombane. Ngenxa yokuba i-motor esebenzayo, iya kuba phantsi kwe-atmospheric overvoltage kunye nokusebenza ngokugqithisileyo kwe-overvoltage: isekethe emfutshane ngequbuliso, ubushushu kunye nombane wendima yexesha elide, ukugquma kuya kuguga ngokuthe ngcembe, ukungcangcazela kunye noxinzelelo lomatshini kuya konakalisa ukugquma, ukongeza, kwinkqubo yokuvelisa ukwenza inani lokumelana novavanyo lwe-voltage, ngalo lonke ixesha, kuya kuvelisa into ethile echuliweyo, ukuwohloka komkhondo, ukuwohloka kwe-cumula. Konke oku kuya kwenza ukuba amandla ombane e-insulation ehle. Ngoko ke, xa uyila isakhiwo sekhoyili, kufuneka kubekho ukhuseleko oluthile.
Ilahleko ye-dielectric ephantsi
Ukulahleka kwe-Dielectric kwenzeka xa isakhiwo sokukhusela siphantsi kwendawo yombane eguqukayo. Ilahleko ye-dielectric yobushushu obuphakathi, nangona ingekho nkulu, kodwa kwiindawo ezibuthathaka zomntu ngamnye kubushushu zigxininiswe ngakumbi, ukuba iindawo ezibuthathaka kubushushu obubangelwa yilahleko ye-dielectric ngaphezu kobushushu obukhutshwayo, ubushushu bendawo yobushushu buya kuqhubeka nokunyuka, ukunyuka kwamaqondo obushushu kunye nokukhuthaza ukwanda okuthe kratya kwilahleko ye-dielectric, ukufakwa kwe-electromechanical ukusebenza kuya kuba kukwehla okubukhali kubukhali beendawo ezibuthathaka ezibangelwa kukuqhekeka kwendawo. Ngoko ke, kwi-high-voltage motor dielectric loss akufanele idlule ixabiso elichaziweyo.
Ukumelana kakuhle ne-corona
Xa ii-motor high-voltage zisebenza, i-corrona phenomenon inokuthi yenzeke ngaphakathi nangaphezulu kwendawo yokugquma, ukukhawuleza ukuguga kunye nokubola kwe-insulation. Ke ngoko, kwiijenereyitha ze-6.3kV nangaphezulu kunye neemotor ze-6kV nangaphezulu, iikhoyili zazo kufuneka zithathe amanyathelo okulwa ne-corona. I-coil ye-6kV motor ayinakuba lunyango oluchasene ne-corona ngokubanzi, kodwa kufuneka ibe lunyango oluchasene ne-corona kwiinjini ezisetyenziswa kwindawo ehluphekileyo okanye enomthamo omkhulu.
Ukusebenza kakuhle kokuguga kwe-thermal
Ukumelana nokushisa kwesakhiwo sokufakelwa kwe-thermal kufuneka kuhlangabezane nenqanaba lokumelana nokushisa elifunwa yimveliso. Ngaphantsi kwesenzo sexesha elide lokushisa okusebenzayo, ubomi obuqhelekileyo benkonzo ye-insulation bunokuqinisekiswa.
Ukugquma kweemoto ngokuqhelekileyo kwahlulwa ku-A, E, B, F, H, amabakala amahlanu okumelana nobushushu. Ngethuba lokusebenza, ubushushu beyona ndawo ishushu kakhulu kwi-motor winding insulation ayiyi kudlula ubushushu obuphezulu obuchazwe kwiklasi yokufakelwa. Ngokubanzi, kuyimfuneko ukushiya umda we-5 ~ 10℃. Ukuba i-insulation structure yenziwe ngezinto zokugquma zamabanga ahlukeneyo okumelana nobushushu, ibakala layo lokumelana nobushushu linokulinganiswa kwaye livavanywe ngokubanzi ngemodeli yalo yesakhiwo.
Inokumelana nendima yoxinzelelo lomatshini
I-insulation ye-coil kufuneka ikwazi ukumelana nomlinganiselo othile woxinzelelo lomatshini ngaphandle kokuphuka okanye ukubangela ukuguqulwa okuyingozi. Ikhoyili esebenzayo ngenxa yokwandiswa kwe-coefficient yocingo kunye ne-insulation ayifani, utshintsho lobushushu, ukugquma kuya kuba phantsi koxinzelelo, ixesha elide i-motor, impembelelo enkulu; Ngenxa yamandla e-electromagnetic, isiphelo sekhoyili siya kuvelisa ukungcangcazela, ngakumbi xa i-motor ichaphazeleka kumjikelezo omfutshane, ukuqala kunye nokunyathela okwangoku, amandla ombane we-electromagnetic ahlala ebangela ukuba ikhoyili ikhubazeke; Ngoko ke, i-insulation iyadingeka ukuba ibe ne-elasticity ethile kunye namandla omatshini.
