1. Zomwe zimayambitsa corona
Corona imapangidwa chifukwa malo amagetsi osagwirizana amapangidwa ndi kondakitala wosagwirizana.Mphamvu yamagetsi ikakwera kufika pamtengo wina pafupi ndi ma elekitirodi ndi kagawo kakang'ono kopindika mozungulira gawo lamagetsi losafanana, kutulutsa kumachitika chifukwa cha mpweya waulere, ndikupanga korona.Chifukwa gawo lamagetsi lomwe lili m'mphepete mwa corona ndilofooka kwambiri ndipo palibe kugundana komwe kumachitika, tinthu tating'onoting'ono tomwe timakhala m'mphepete mwa corona ndi ma ion amagetsi, ndipo ma ion awa amapanga ma corona discharge pano.Mwachidule, corona amapangidwa pamene kondakitala elekitirodi yokhala ndi utali wozungulira waung'ono wa curvature imatuluka mumlengalenga.
2. Zomwe zimayambitsa corona m'magalimoto othamanga kwambiri
Malo amagetsi a stator winding of high-voltage motor amakhazikika pamipata ya mpweya wabwino, mipata yotulukira mizere, ndi malekezero opindika.Mphamvu yamunda ikafika pamtengo wina pamalo amderalo, mpweya umalowa m'malo a ionization, ndipo fulorosisi ya buluu imawonekera pamalo a ionized.Ichi ndiye chochitika cha corona..
3. Kuopsa kwa corona
Korona imapanga matenthedwe ndi ozone ndi nitrogen oxides, zomwe zimawonjezera kutentha kwanuko mu koyilo, zomwe zimapangitsa kuti zomatira ziwonjezeke ndikuwonongeka, komanso kutchinjiriza kwa chingwe ndi mica kukhala yoyera, zomwe zimapangitsa kuti zingwezo zisakhale zotayirira, zazifupi. kuzunguliridwa, ndi zaka za insulation.
Kuphatikiza apo, chifukwa chosalumikizana bwino kapena kusakhazikika pakati pa thermosetting insulating padenga ndi khoma la thanki, kutulutsa kwamoto mumpata wa thanki kumachitika chifukwa cha kugwedezeka kwamagetsi.Kukwera kwa kutentha komweko komwe kumachitika chifukwa cha kutulutsa kumeneku kudzawononga kwambiri malo otsekemera.Zonsezi zidzawononga kwambiri kutsekemera kwa mota.
4. Njira zopewera corona
(1) Nthawi zambiri, zotchingira za injiniyo zimapangidwa ndi zinthu zosagwira corona, ndipo utoto woviika umapangidwanso ndi utoto wosamva corona.Popanga mota, zovuta zogwirira ntchito ziyenera kuganiziridwa kuti zichepetse kuchuluka kwamagetsi.
(2) Popanga koyilo, kulungani tepi yotsutsa dzuwa kapena kupaka utoto wotsutsa dzuwa.
(3) Mipata ya pachimake imapopedwa ndi utoto woletsa kufalikira, ndipo ma slot amapangidwa ndi ma semiconductor laminates.
(4) Pambuyo pokonza zotchingira zotsekera, choyamba gwiritsani ntchito utoto wocheperako wosakanika wa semiconductor pamalo owongoka.Kutalika kwa utoto kuyenera kukhala 25mm mbali iliyonse kuposa kutalika kwapakati.Utoto wa semiconductor wosakanizidwa pang'ono nthawi zambiri umagwiritsa ntchito utoto wa 5150 epoxy resin semiconductor, womwe kukana kwake ndi 103~105Ω.
(5) Popeza kuti mphamvu zambiri zamagetsi zimayenda kuchokera pagawo la semiconductor kupita kumalo oyambira, kuti mupewe kutentha komweko komwe kumatuluka, kutetezedwa kwapamwamba kuyenera kuchulukira pang'onopang'ono kuchokera polowera mpaka kumapeto.Choncho, pangani utoto wopingasa kwambiri wa semiconductor kamodzi kuchokera kufupi ndi nsonga yotulukira yokhotakhota mpaka kumapeto kwa 200-250mm, ndipo malo ake akuyenera kuphatikizira utoto wa semiconductor wochepera 10-15mm.Utoto wosakanizidwa kwambiri wa semiconductor nthawi zambiri umagwiritsa ntchito utoto wa 5145 alkyd semiconductor, womwe mphamvu yake yapamtunda ndi 109 mpaka 1011.
(6) Pamene utoto wa semiconductor ukadali wonyowa, kulungani theka la riboni yagalasi yokhuthala ya 0.1mm mozungulira.Njira yothira waxing ndikuyika riboni yagalasi yopanda alkali mu uvuni ndikutenthetsa mpaka 180 ~ 220 ℃ kwa maola 3 ~ 4.
(7) Kunja kwa riboni yagalasi, ikani wosanjikiza wina wa penti ya semiconductor yosakanizika ndi utoto wopingasa kwambiri wa semiconductor.Zigawozo ndi zofanana ndi masitepe (1) ndi (2).
(8) Kuphatikiza pa chithandizo cha anti-halation kwa ma windings, pachimake chimafunikanso kupopera utoto wa semiconductor wosakanizidwa kwambiri musanatuluke pamzere wa msonkhano.Ma groove wedges ndi groove pads ayenera kupangidwa ndi matabwa a semiconductor galasi fiber nsalu.
