Kutheni le nto abavelisi beJenereyitha beFakela iibhrashi zokuGqiba kwi-Shafts

I-shaft ixhotyiswe nge-brush yokumisa, ukwenzela ukuba i-shaft yangoku inokuthi isekelwe kwi-brush, ukwenzela ukunciphisa umonakalo kwi-bearing, eyona nto ingcono kunokukhethwa kwesihlalo sokuthwala i-insulating.

Ngenxa yokuba i-gap yomoya ayisoloko ifana ngokufanayo kufakelo lwejeneretha, kwaye i-impedance ekufakeni ezinye iikhoyili azifani, i-generator iya kubangela ukuba i-shaft voltage isebenze kwi-rotor ye-generator.Ngenxa yobukho bombane we-shaft, i-voltage inokwaphula ifilimu yeoli ngokusebenzisa iibheringi ze-rotor kuzo zombini iziphelo ukwenza i-shaft current kwaye itshise i-bearing bush esebenzayo.Ukuze kuthintelwe le nto, i-insulation yongezwa kwi-generator excitation end bushing seat (yonke i-bearing is insulated ukusuka emhlabeni), kunye ne-grounding carbon brush isetyenziswe kwi-steam end shaft enkulu.Olunye ugcino lwe-generator ye-excitation kunye nomlinganiselo we-rotor wokugquma komhlaba ngokwenene yi-shaft enkulu ye-carbon brush.

Uthini umgaqo we-grounding carbon brush of umenzi wejenereyitha ?

Umbane we-shaft owenziwe kukufana kwe-gap yomoya okanye umahluko we-coil impedance obangelwa yimpazamo yofakelo lwemoto yenza i-loop ngebrashi yekhabhoni kunye neqokobhe, idlula ukuthwala.I-short-circuit i-cross-voltage yefilimu yeoli yokuphuka kwimiphetho yomibini yokuthintela ukuthintela ukubunjwa kwe-axial current ye-ablative bearing okanye i-bush.Ibrashi yekhabhoni yomhlaba kusetyenziswa umzekelo kwiijenereyitha ezinkulu, isiphelo esinesiphelo esinesitulo esinesigqubuthelo (i-insulation), icala lomphunga elikhulu elibeka ibrashi yekhabhoni, ngenxa yolondolozo olwahlukeneyo kunye nerotha yomlinganiselo wochulumanco wejenereyitha womhlaba wokugquma uyafunyanwa ngokwenene. icala lomphunga we-carbon brush shaft, xa i-rotor ijika kwi-rotor iron core leakge, i-excitation ye-positive okanye i-negative yomhlaba iya kuba ne-voltage yokumisa, Ibonisa ukuba i-rotor iphosakele kwaye kufuneka ivalwe ukugcinwa.Ibrashi yokugawula ixhunywe ngokubanzi kwi-rotor insulation loop yokubeka iliso, ixesha lokuhamba langoku ukubhengeza uphawu lwe-alarm.

I-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. esekwe ngo-2006, ngumvelisi wejenereyitha ye-diesel e-China, edibanisa ukuyila, ukubonelela, ukuthunyelwa kunye nokugcinwa kweseti yejeneretha ye-diesel.Imveliso igubungela iCummins, iPerkins, iVolvo, iYuchai, iShangchai, iDeutz, iRicardo, iMTU, Weichai njl kunye noluhlu lwamandla 20kw-3000kw, kwaye ube ngumzi-mveliso wabo we-OEM kunye neziko lobuchwepheshe.
