Iyo coil insulation yehigh voltage motorine simba rakakura pahupenyu hwesevhisi uye hupfumi hwekuita kwemota, rinova dambudziko iro mugadziri wese uye tekinoroji anofanira kunyatso funga. Iyo yakakwira-voltage coil inogona kunzi moyo wemota kune imwe nhanho, iyo inosarudza zvakananga hupenyu hwesevhisi yemota, uye kuita kweiyo insulating zvinhu, iyo yakakosha chikamu checoil, yakakosha.
Iyo yekumisikidza chimiro uye kurapwa maitiro eakakwira-voltage motors munyika dzakasiyana anogona kupfupikiswa sezvinotevera:
(1) Multi-adhesive mica tape inoramba yakaputirwa, vacuum yakaomeswa, uye ipapo inopisa yakadzvanywa (yakaumbwa kana hydraulic).
(2) Multi-adhesive mica tape inoramba yakaputirwa, isina vacuum kuomeswa, uye yakananga kuumbwa nekuumbwa kunopisa.
(3) Ishoma inonamira mica tepi inoramba yakaputirwa, vacuum yakanyudzwa musolventless resin, uyezve inopisa inogadzirwa.
(4) Iyo mica tape (kana chena embryo tepi) inoramba yakaputirwa, ndiko kuti, mutsara unopararira, uye ipapo iyo inonyungudutsa-isina resin inoiswa mukati mese.
Mukuwedzera, kune silicone rubber insulation, pamwe nesilicone rubber uye mica tape yakasanganiswa insulation. Kudzivira kupisa, kutonhora kupikisa, kusimba kwehunyoro uye kushorwa kwesilicone rabha zvakanakisa, asi kushanda kwemagetsi uye simba rekubvarura hazvina kunaka, uye inongoshandiswa kune akakwira-voltage mota anoshanda munzvimbo dzakakosha dziri pasi pe6 kV.
Basic zvinodiwa pakakwirira voltagecoil insulation:
Simba remagetsi rakakwana
Kune rumwe rutivi, zvinodikanwa kuti kuvharwa kwemotor kuve kwakaonda sezvinobvira, asi kune rumwe rutivi, kunodiwa kuve nechero margin maererano nesimba remagetsi. Nekuti mota iri kushanda, ichave iri pasi pemhepo yakawandisa uye yekushanda overvoltage kukanganisa: kamwe kamwe kapfupi dunhu, tembiricha uye voltage yebasa renguva refu, iyo insulation inozochembera zvishoma nezvishoma, vibration uye kushushikana kwemagetsi kuchakuvadzawo kuvharidzira, mukuwedzera, mukugadzira maitiro kuita nhamba yekumira bvunzo yevoltage, nguva dzese, inoburitsa imwe yakavanzika yekushatisa maitiro, iyo inodonhedza mhedzisiro yeinodonhedza maitiro. Zvese izvi zvinoita kuti simba remagetsi rekuisa insulation riderere. Naizvozvo, kana uchigadzira iyo coil chimiro, panofanira kunge paine imwe chengetedzo chinhu.
Kurasikirwa kwe dielectric
Dielectric kurasikirwa kunoitika kana insulating dhizaini inoiswa kune inochinjana yemagetsi munda. Dielectric kurasikirwa kweavhareji yekupisa, kunyangwe isiri yakakura, asi mune imwe neimwe isina simba mapoinzi pakupisa inonyanya kudzika, kana iyo isina simba mapoinzi pakupisa kunokonzerwa nekurasikirwa kwedielectric kupfuura kupisa kunoburitswa, tembiricha yemuno yekuvharisa icharamba ichikwira, tembiricha inokwira uye inosimudzira kuwedzera kwekurasikirwa kwedielectric, kuvharwa kweiyo electromechanical kuita kuchave kuderera kwakanyanya mukuomarara kwenzvimbo dzisina kusimba dzenzvimbo. Naizvozvo, mune yakakwira-voltage mota dielectric kurasikirwa haifanire kudarika kukosha kwakatarwa.
Kuramba kwakanaka kwekorona
Kana ma-high-voltage motors ari kushanda, corona phenomenon inogona kuitika mukati uye pamusoro peiyo insulation, ichimhanyisa kuchembera uye kukora kweiyo insulation. Naizvozvo, kune majenareta e6.3kV uye pamusoro uye mota dze6kV uye pamusoro, makoiri avo anofanirwa kutora matanho ekurwisa corona. Iyo coil ye6kV mota haigone kuve anti-corona kurapwa kazhinji, asi inofanirwa kunge iri anti-corona kurapwa kwemamotors ayo anoshandiswa munzvimbo isina kunaka kana nehukuru hukuru.
Good thermal kuchembera kuita
Kupisa kwekupisa kwechimiro chekudzivirira kwekushisa kunofanira kusangana negiredhi rekudzivirira kupisa rinodiwa nechigadzirwa. Pasi pechiito chenguva refu chekushisa kwekushanda, hupenyu hwese hwebasa hwekudzivirira hunogona kuvimbiswa.
Mota insulation inowanzo kupatsanurwa kuita A, E, B, F, H mashanu ekupisa magiredhi. Panguva yekushanda, tembiricha yenzvimbo inopisa kwazvo mumhepo inotenderedza mhepo haipfuure tembiricha yakanyanya inotsanangurwa mukirasi yekudzivirira. Kazhinji, zvinodikanwa kusiya muganho we5 ~ 10 ℃. Kana iyo insulation dhizaini yakaumbwa nezvinhu zvekudzivirira zvemagiredhi akasiyana ekupisa kupisa, giredhi rayo rekudzivirira kupisa rinogona kuedzerwa uye kuongororwa zvizere kuburikidza nemhando yechimiro.
Inogona kumira basa rekushushikana kwemagetsi
Iko kusungirirwa kwekoiri kunofanirwa kukwanisa kumira nehumwe huwandu hwekushushikana kwemagetsi pasina kutyora kana kukonzera deformation inokuvadza. Coil iri kushanda nekuda kwekuwedzera coefficient yewaya uye insulation haina kufanana, tembiricha shanduko, insulation ichave pasi pekunetsekana, iyo yakareba mota, iyo yakakura kukanganisa; Nekuda kwesimba remagetsi, kupera kwekoiri kunoburitsawo kuzununguka, kunyanya kana mota ichibatwa nepfupi, kutanga uye braking ikozvino, iyo electromagnetic simba rinowanzo konzera kuti coil iparare; Naizvozvo, iyo insulation inodiwa kuti ive neimwe elasticity uye mechanical simba.
