Iibhrashi zekhabhoni zokumisa iMorteng zizinto eziphambili kwiimotor ezijikelezayo (ezifana neejenereyitha kunye neenjini zombane), ezisetyenziselwa ukuphelisa imisinga ye-shaft, ukukhusela ukhuseleko lwezixhobo, kunye nokuncedisa iinkqubo zokubeka iliso. Iimeko zokusetyenziswa kwazo kunye nemisebenzi imi ngolu hlobo lulandelayo:
I.IMisebenzi engundoqo kunye neziphumo
- Xa i-generator okanye i-motor isebenza, i-asymmetry kwintsimi yamagnetic (efana nezikhala zomoya ezingalinganiyo okanye umahluko kwi-impedance ye-coil) inokubangela i-shaft voltage kwi-shaft ejikelezayo. Ukuba i-voltage ye-shaft igqabhuka kwifilimu eneoyile, inokwenza i-shaft yangoku, ekhokelela kwi-shaft ethwele i-electrolysis, ukuthotywa kwe-lubricant, kunye nokungaphumeleli kokuthwala.
- Iibhrashi zekhabhoni ze-Morteng zokumisa i-short-circuit i-rotor shaft ukuya kwindlu yomatshini, ukuphambukisa imisinga ye-shaft emhlabeni kwaye ibathintele ukuba bahambe ngeebheringi. Umzekelo, iijenereyitha ezinkulu zihlala zifakela iibhrashi zekhabhoni ezisezantsi ekupheleni kweinjini yomoya, ngelixa iibheringi zesiphelo sovuselelo zifakelwe iipads zokugquma, zenza uqwalaselo lwakudala 'lokuxhokonxa isiphelo sokugquma + i-iturbine end grounding'.
II. Iimeko zosetyenziso oluqhelekileyo
-Iijeneretha ze-Thermal / hydropower: Iibhrashi zekhabhoni ze-Morteng zifakwe kwisiphelo se-turbine, ngokubambisana neebheringi ezifakwe kwi-insulated ekupheleni kwe-excitation, ukuphelisa ukuvuza kwe-voltage ye-shaft ye-magnetic induction. Umzekelo, kwiijenereyitha zombane wamanzi, iibearings zethrust zixhomekeke kuphela kwifilimu yeoli ebhityileyo yokugquma, kwaye ukumisa iibhrashi zekhabhoni kunokuthintela i-electrolysis yamaqokobhe okuthwala.
-Ii-injini zomoya: Isetyenziselwa i-rotors ye-generator okanye iinkqubo zokukhusela i-surge, izixhobo zihlala zikhethwa kwi-graphite yensimbi (i-copper / i-silver-based), enika i-conductivity ephezulu, ukuxhatshazwa kokugqoka, kunye nokuchasana kwangoku.
-I-high-voltage / i-variable-frequency motors: Ezi zinomngcipheko ophezulu we-shaft current. Umzekelo, iTonghua Power Generation Company ifakele iibhrashi zekhabhoni ezisezantsi kwisiphelo somqhubi wemoto ephambili, isebenzisa imithombo yoxinzelelo rhoqo ukugcina u-zero onokubakho, ngaloo ndlela isombulula umba wokuba iibheringi zantlandlolo ezigqunyiweyo azikwazanga ukuvimba ngokupheleleyo ishaft yangoku.
-Ukuthuthwa komzila kaloliwe: Kwii-motor traction of locomotives zombane okanye ii-diesel locomotives, iibrashi ze-carbon grounding zisusa ukuqokelelwa kombane osisigxina ngexesha lokusebenza, ukukhusela iibheringi kunye nokugcina uzinzo lwenkqubo yombane.
