Morteng yekugadzika kabhoni mabhurashi zvinhu zvakakosha mumamota anotenderera (senge majenareta uye mota dzemagetsi), anonyanya kushandiswa kubvisa shaft currents, kuchengetedza kuchengetedzwa kwemidziyo, uye kubatsira masystem ekutarisa. Maitiro avo ekushandisa uye mabasa ndeaya anotevera:
I.Core Mabasa uye Migumisiro
- Kana jenareta kana mota ichimhanya, asymmetry mundima yemagineti (senge isina kuenzana mhepo migero kana misiyano mucoil impedance) inogona kupinza shaft voltage mune inotenderera shaft. Kana iyo shaft voltage ikapaza neinotakura mafuta firimu, inogona kuumba shaft ikozvino, inotungamira kune shaft ine electrolysis, mafuta ekuzora, uye kunyangwe kutadza kubereka.
- Morteng inogadzika kabhoni mabhurashi ipfupi-inotenderera rotor shaft kune muchina imba, inotsausa shaft mafungu pasi uye nekudzivirira kuti isayerera nemumabheya. Semuyenzaniso, majenareta mahombe anowanzo gadza mabhurashi ekabhoni anogadzika kumagumo eturbine, ukuwo mabheji ekunakisa akaiswa mapedhi anodzivirira, achigadzira dhizaini 'excitation end insulation + turbine end grounding' kugadzirisa.
II. Mamiriro Ekushandisa Akajairika
-Thermal / hydropower jenareta: Morteng inogadzika kabhoni mabhurashi akaiswa kumagumo eturbine, pamwe chete neakavharirwa mabheji pakupera kwekunakidzwa, kubvisa kuvuza kwemagineti induction shaft voltage. Semuyenzaniso, mumajenareta emagetsi ehydropower, ma thrust bearings anovimba chete neoiri firimu rakatetepa kuti rivhare, uye kugadzika mabhurashi ekabhoni kunogona kudzivirira electrolysis yemakanda anotakura.
-Wind turbines: Inoshandiswa kune generator rotors kana surge protection systems, zvinhu zvinowanzosarudzwa kubva kune metallic graphite (copper / silver-based), iyo inopa high conductivity, kupfeka kusagadzikana, uye kupera kwemazuva ano.
-High-voltage / variable-frequency motors: Aya ane ngozi yakawanda ye shaft ikozvino. Semuyenzaniso, Tonghua Power Generation Company yakaisa mabhurashi ekugadzika kabhoni pamagumo emota yekutanga fan mota, ichishandisa zvitubu zvinogara zvichitsikirira kuchengetedza zero, zvichigadzirisa nyaya yekuti mabearings ekutanga akavharirwa haakwanise kuvharisa shaft ikozvino.
-Kutakurwa kwenjanji: Mukufambisa mota dzemagetsi emagetsi kana dizeli locomotives, kugadzika kabhoni mabhurashi anobvisa static kuunganidzwa kwemagetsi panguva yekushanda, kuchengetedza mabheji, uye kuchengetedza magetsi system kugadzikana.
