Iyo stator windings yeanoputika-proof motors ane mapfupi-edunhu matambudziko, kunyanya anosanganisira interphase pfupi-circuit (nhatu-chikamu kana maviri-chikamu mapfupi-dunhu) uye inter-turn pfupi-circuit, izvo zvinowanzo konzerwa nekukuvara kwekudzivirira.Mukutarisana nemamiriro ezvinhu aya, matanho akakodzera anofanirwa kutorwa kuti agadzirise kukuvara kwemotokari kana njodzi dzekuchengetedza.
Interphase short circuit treatment: Kana iyo interphase short circuit ikaitika, nekuda kwekuderera kwenhamba yekutendeuka uye shanduko yekutsvedza, iyo impedance yemota inoderedzwa, uye iko zvino kupinza kubva kune magetsi kuchawedzera nekukurumidza.Kuti udzivise kuwandisa kwemota uye kukuvadzwa kwemhepo, yakajairika kugadzirisa kushanda ndeye kukurumidza kudzima magetsi, sekuvhara redunhu breaker kana fuse.Kana kurapwa kwakanonoka, ma windings anogona kukuvara.Panyaya yezvikamu zviviri kana zvitatu-chikamu chipfupi chedunhu, kana chinzvimbo chechikamu chimwe nechimwe chipfupi chedunhu chinopesana, chinogona kutungamira kune asymmetrical kushanda kwemota, kutevedzana kwakashata ikozvino uye mamwe mamiriro asina kujairika, izvo zvinokanganisa mashandiro uye hupenyu hwemota.
Interturn short circuit treatment: interturn short circuit zvinoreva kuitika kweshort circuit pakati pemakoiri mumhepo imwe chete.Izvi zvinogona kukonzera ruzha rwemota isina kujairika uye kudedera.Iyo nzira yekurapa inonyanya kugadzirisa mota nekugadzirisa kana kutsiva yakakuvadzwa inomonereka chikamu.Panguva imwecheteyo, mamwe ma windings anodawo kutariswa kuti ave nechokwadi chekuti hapana mamwe matambudziko anogona kuitika.
Izvo zvinofanirwa kucherechedzwa kuti iyo interphase pfupi dunhu rekuputika-proof mota ndiyo yakanyanya kuoma, kunyanya iyo kesi inoitika pakupera kwe stator mhepo.Kana mhepo ipfupi-yakatenderedzwa pakati pekutendeuka, iwo akakuvadzwa anotendeuka anopisa nekukasira, izvo zvinogona kutungamira mukukuvadzwa kwekudzivirira kana kutopisa.Uye zvakare, mota inogona kuburitsa ruzha rusina kujairika, inova chiratidzo chiri pachena.
Kazhinji, kana stator mhepo yemotokari inoputika-inoputika ipfupi-inotenderera, danho rekutanga nderekucheka magetsi nekukasira kudzivirira kukuvara kwemota kana matambudziko ekuchengetedza.Zvadaro, kunyatsoongorora uye kugadzirisa kunodiwa kugadzirisa chikamu chakakanganisika chemhepo uye kuona kuti mota inodzokera kune yakajairika kushanda.Kana mamiriro acho akanyanya kuoma, zvingangoda kudzika kwakadzika kuchengetedzwa uye kuongororwa nenyanzvi kuti ive nechokwadi chekuita uye kuchengetedzwa kwemota.Panguva imwecheteyo, kugara uchiyedza kuvharidzira uye kugadzirisa kwakakosha kudzivirira kupemha matambudziko edunhu mapfupi.
