Izinto ezibangela i-corona kwi-motor-high-voltage windings

1. oonobangela becorona

I-Corona iveliswa ngenxa yokuba indawo yombane engalinganiyo yenziwa ngumqhubi ongalinganiyo. Xa i-voltage iphakama kwixabiso elithile kufuphi ne-electrode kunye ne-radius encinci ye-curvature ejikeleze intsimi yombane engalinganiyo, ukukhutshwa kuya kwenzeka ngenxa yomoya okhululekile, okwenza i-corona.Ngenxa yokuba intsimi yombane kwi-periphery ye-corona ibuthathaka kakhulu kwaye akukho ukuhlukana kwe-collision kwenzeka, iinqununu ezihlawulisiweyo kwi-periphery ye-corona ziyi-ion zombane, kwaye ezi ionni zenza i-corona yokukhupha okwangoku.Ukubeka ngokulula, i-corona iveliswa xa i-electrode ye-conductor ene-radius encinci ye-curvature ikhuphela emoyeni.

2. Izinto ezibangela i-corona kwiimotor ezine-voltage ephezulu

Intsimi yombane ye-stator winding ye-high-voltage motor igxininiswe kwiindawo zokubeka umoya, iindawo zokuphuma ezinqamlekileyo, kunye neziphelo ezijikelezayo. Xa amandla entsimi afikelela kwixabiso elithile kwindawo yendawo, igesi ifumana i-ionization yendawo, kunye ne-blue fluorescence ibonakala kwindawo ye-ionized. Le yimeko yecorona. .

3. Iingozi zecorona

I-corona ivelisa iziphumo ze-thermal kunye ne-ozone kunye ne-nitrogen oxides, eyandisa ubushushu bendawo kwikhoyili, ibangela ukuba i-adhesive ibe mbi kwaye i-carbonize, kunye ne-strand insulation kunye ne-mica ibe mhlophe, nto leyo ibangela ukuba imisonto ikhululeke, ibe mfutshane- ukujikeleza, kunye neminyaka yokugquma.
Ukongeza, ngenxa yonxibelelwano olulambathayo okanye olungazinzanga phakathi kwendawo yokugquma i-thermosetting kunye nodonga lwetanki, ukukhutshwa kwentlantsi kwisithuba esisetankini kuya kubangwa phantsi kwesenzo sokungcangcazela kwe-electromagnetic vibration.Ukunyuka kobushushu bendawo okubangelwa koku kukhutshwa kwentlantsi kuya kuwukhukulisa ngokunzulu umphezulu wokugquma.Konke oku kuya kubangela umonakalo omkhulu kwi-motor insulation.

4. Amanyathelo okuthintela i-corona

(1) Ngokubanzi, izinto zokugquma zenjini zenziwe ngezinto ezikwaziyo ukumelana ne-corona, kwaye ipeyinti yokudipha yenziwe ngepeyinti ekwaziyo ukumelana ne-corona. Xa uyila i-motor, iimeko zokusebenza ezinzima kufuneka zithathelwe ingqalelo ukunciphisa umthwalo we-electromagnetic.

(2) Xa usenza ikhoyili, bhinqa iteyiphu echasene nelanga okanye usebenzise ipeyinti echasene nelanga.

(4) Emva konyango lokugquma, qala usebenzise ipeyinti ye-semiconductor enganyangekiyo kwindawo ethe tye ekujikeni. Ubude bepeyinti kufuneka bube ngama-25mm ubude kwicala ngalinye kunobude obuphambili.Ipeyinti ye-semiconductor engaxhathisiyo ngokubanzi isebenzisa ipeyinti ye-5150 epoxy resin semiconductor yepeyinti, exhathisa umphezulu yi-103~105Ω.

(5) Ekubeni ininzi ye-capacitive yangoku ihamba ukusuka kuluhlu lwe-semiconductor ukuya kwi-outlet engundoqo, ukuze ugweme ukufudumeza kwendawo kwindawo yokuphuma, ukuxhathisa umphezulu kufuneka kwandiswe ngokuthe ngcembe ukusuka kwindawo yokuphuma ukuya ekupheleni.Ke ngoko, sebenzisa ipeyinti ye-semiconductor yokumelana okuphezulu kube kanye ukusuka kwindawo yenotshi yokuphuma ejikajikayo ukuya ekupheleni kwe-200-250mm, kwaye indawo yayo kufuneka idibane nepeyinti ye-semiconductor yokumelana ne-10-15mm.Ipeyinti yokumelana okuphezulu kwe-semiconductor ngokuqhelekileyo isebenzisa ipeyinti ye-alkyd semiconductor eyi-5145, enokumelana nomphezulu we-109 ukuya ku-1011.

(6) Ngelixa ipeyinti ye-semiconductor isemanzi, yisonge umaleko wesiqingatha se-0.1mm eshinyeneyo yeribhoni yeglasi eyenziwe ngeweksi ukuyijikeleza.Indlela ye-dewaxing kukubeka iribhoni yeglasi engena-alkali kwi-oveni kwaye uyifudumeze ukuya kwi-180 ~ 220℃ ngeeyure ezi-3 ~ 4.

7 Amalungu ayafana namanyathelo (1) kunye no-(2).

(8) Ukongeza kwi-anti-halation unyango kwii-windings, i-core nayo idinga ukutshizwa ngepeyinti ye-semiconductor ephantsi yokumelana ngaphambi kokuphuma kumgca wokuhlanganisa.I-groove wedges kunye ne-groove pads kufuneka zenziwe nge-semiconductor glass fiber cloth sheets.
