Kana chikanganiso chipfupi chedunhu chikaitika pakati pekutendeuka kwemota stator winding, inowanzotongwa nekuyera iyo DC.

Nekudaro, iyo DC kuramba kweiyo stator mhepo yemota ine hukuru hukuru idiki kwazvo, uye inozokanganiswa nehukama pakati pechiridzwa chechokwadi uye kuyerwa kukanganisa. Hazvisi nyore kuwana mutongo chaiwo. Nzira inotevera inogona kushandiswa kutonga.

Fault diagnosis method:

Panzvimbo pekubvisa mota, shandisa imwe-phase auto-voltage regulator ine hunyanzvi hwakakodzera kuwedzera zvishoma nezvishoma voltage kubva pakatanga uye kuunza yakaderera-voltage alternating ikozvino kune chimwe chezvikamu.Panguva imwecheteyo, shandisa clamp ammeter kuyera ikozvino, kuitira kuti ikozvino inokwira kusvika kune 1/3 yehuwandu hwehuwandu hwemotokari.

Zvadaro, mira kuwedzera uye shandisa multimeter kuyera iyo induced voltages yezvimwe zvikamu zviviri. Kana chimwe chikamu chine inter-turn short circuit kukanganisa, iyo induced voltage ichave yakaderera pane imwe nhanho.Chinja chikamu chimwe chemagetsi uye kuyera iyo induced voltage yemamwe maviri matanho nenzira imwecheteyo.

Zvichienderana nekuti iyo induced voltages yakafanana here, inogona kutongwa kana paine inter-turn short circuit kukanganisa.Dambudziko rekukanganisa kwedunhu pfupi pakati pekutendeuka kwemota stator rinowanzogadziriswa nekutsiva mhepo inotenderera panguva yekugadzirisa mota.

Chii chekuita kana iyo insulation ikaputsika pakati pekutendeuka kwemota?

Dambudziko rekupokana kwekudzivirira pakati pekutendeuka kwemota kunosanganisira kushomeka kwezvinhu pakati pekutendeuka kwemota, kukuvadzwa kweiyo insulation pakati pekutenderera panguva yekutenderera uye inlaying, kusakwana kwehutete hwekuvharira pakati pekutendeuka kana kusanzwisisika chimiro, nezvimwe, izvo zvese zvinokonzeresa insulation. kuparara kwekuparara pakati pekutendeuka kwemota. kuitika kwezviitiko.

Nzira yekuyedza sei insulation pakati pekutendeuka kwemota stator winding?

Kuti uve nechokwadi chekushanda kwakajairika kwemota, iyo inter-turn insulation test yemota stator winding inodiwa. Kunyangwe iri ichangobva kuiswa mukushanda kana mota inomhanya, zvinodikanwa kuita iyo inter-turn insulation test.
