1. Zvikonzero zvekorona
Corona inogadzirwa nekuti isina kuenzana munda wemagetsi unogadzirwa neasina kuenzana conductor. Kana iyo voltage ichikwira kune imwe kukosha padyo ne electrode ine diki curvature radius yakatenderedza isina kuenzana munda wemagetsi, kubuda kuchaitika nekuda kwemhepo yakasununguka, kuumba korona.Nekuti nzvimbo yemagetsi iri padyo nekorona haina kusimba uye hapana kudhumhana kunoitika, zvikamu zvinochajiswa panharaunda yekorona zvinonyanya maion emagetsi, uye maion aya anoumba corona discharge current.Zvichitaurwa zviri nyore, corona inogadzirwa kana conductor electrode ine diki radius ye curvature inobuda mumhepo.
2. Zvikonzero zvekorona mune yakakwira-voltage motors
Munda wemagetsi we stator winding ye high-voltage motor inonamirwa pamhepo inotsvedza, linear exit slots, uye mhepo inopera. Kana simba remunda richisvika kune imwe kukosha panzvimbo yenzvimbo, gasi rinopinda ionization yemunharaunda, uye blue fluorescence inoonekwa panzvimbo yeionized. Ichi ndicho chiitiko chekorona. .
3. Ngozi dzekorona
Iyo corona inogadzira zvinopisa zvinokonzeresa uye ozone uye nitrogen oxides, izvo zvinowedzera tembiricha yemuno mucoil, zvichiita kuti kunamira kwacho kushatise uye kuve necarbonize, uye iyo strand insulation uye mica iite chena, izvo zvinozoita kuti tambo dzive dzakasununguka, pfupi- kutenderera, uye mazera ekudzivirira.
Uye zvakare, nekuda kwekusagadzikana kana kusagadzikana kusangana pakati peiyo thermosetting insulating pamusoro uye tangi madziro, spark discharge mugomba mutangi inokonzereswa pasi pechiito che electromagnetic vibration.Kukwira kwetembiricha yemuno kunokonzerwa neiyi spark discharge inoshatisa zvakanyanya iyo insulation surface.Zvese izvi zvinokonzeresa kukuvadza kukuru kune iyo mota insulation.
4. Matanho ekudzivirira corona
(1) Kazhinji, iyo insulation material yemota inogadzirwa necorona-resistant material, uye pendi yekunyudza inogadzirwawo necorona-resistant pendi. Paunenge uchigadzira mota, mamiriro ekushanda akaomarara anofanirwa kutariswa kudzikisa mutoro wemagetsi.
(2) Paunenge uchigadzira coil, putira anti-zuva tepi kana shandisa anti-zuva pendi.
(3) Iyo inotsvedza yepakati yakapfapfaidzwa nependi-inodzivirira-inotumbuka pendi, uye iyo slot pads inogadzirwa semiconductor laminates.
(4) Mushure mekugadzirisa kwekudzivirira kwekudzivirira, tanga waisa pendi yepasi-resistant semiconductor pane yakatwasuka yemhepo. Kureba kwepende kunofanirwa kureba 25mm kune rumwe rutivi kupfuura kureba kwepakati.Pendi yakaderera-resistance semiconductor inowanzo shandisa 5150 epoxy resin semiconductor pendi, iyo inopikisa pamusoro i103~105Ω.
(5) Sezvo mazhinji eiyo capacitive ikozvino inoyerera ichibva kune semiconductor layer ichipinda mupakati pekubuda, kuitira kuti udzivise kupisa kwenzvimbo pakubuda, iyo yekudzivirira yepasi inofanira kuwedzera zvishoma nezvishoma kubva pamhepo yekubuda kusvika kumagumo.Nokudaro, shandisa pendi yepamusoro-resistant semiconductor kamwe chete kubva pedyo nemhepo inoputika inobuda kusvika kumagumo e200-250mm, uye nzvimbo yayo inofanira kupindirana nependi yepasi-resistant semiconductor ne 10-15mm.High-resistance semiconductor pendi inowanzoshandisa 5145 alkyd semiconductor pendi, iyo yepamusoro resistivity iri 109 kusvika 1011.
(6) Nepo pendi yesemiconductor ichiri kunyorova, putira hafu yeribhoni gobvu regirazi regirazi rakaipoteredza.Nzira yekubvisa waxing ndeyekuisa alkali-isina girazi ribhoni muovheni uye kupisa kusvika 180 ~ 220 ℃ kwe3 ~ 4 maawa.
(7) Kunze kweribhoni regirazi, shandisa imwe pende yepasi-resistance semiconductor pendi uye yakakwirira-resistance semiconductor pendi. Zvikamu zvakafanana nematanho (1) uye (2).
(8) Kuwedzera kune anti-halation kurapwa kwema windings, musimboti zvakare unofanirwa kupfapfaidzwa nepasi-resistant semiconductor pendi isati yabva pamutsetse wegungano.Iyo groove wedges uye groove pads inofanira kugadzirwa semiconductor girazi fiber jira mabhodhi.
