Sei Vagadziri veJenareta vachiisa Grounding Brushes paShafts

Iyo shaft yakashongedzerwa nebhurashi repasi, kuitira kuti shaft ikozvino igadziriswe kuburikidza nebhurashi, kuitira kuderedza kukuvadza kune kutakura, izvo zviri nani pane kusarudzwa kwekuisa insulating chigaro chekutakura.

Nemhaka yokuti gaka remhepo harisi nguva dzose rakafanana pakugadzwa kwejenareta, uye iyo impedance mukuiswa kwemamwe makoiri haina kupotsa yakafanana, jenareta ichaita kuti shaft voltage pajenareta rotor ishande.Nekuda kwekuvapo kweshaft voltage, iyo voltage inogona kuputsa firimu remafuta kuburikidza nemabhengi e rotor kumativi ese maviri kuita shaft ikozvino uye kupisa gwenzi rinotakura riri kushanda.Kuti udzivise chiitiko ichi, insulation inowedzerwa kune jenareta excitation end bushing seat (iyo yese fani yakavharidzirwa kubva pasi), uye grounding kabhoni brashi inoshandiswa mumhepo inopera shaft hombe.Imwe jenareta yekukurudzira kugadzirisa uye kuyerwa kwerotor yekudzivirira kwevhu ndiyo shaft hombe yekabhoni brashi.

Ndeipi musimboti wekugadzika kabhoni brashi ye mugadziri jenareta ?

Iyo shaft voltage inokonzereswa nemhepo gap kufanana kana coil impedance musiyano unokonzerwa nekukanganisa kwekumisikidzwa kwemota inoumba loop kuburikidza nekabhoni bhurashi uye goko, ichipfuura kutakura.Short-circuit the cross-voltage of the breakdown oil film at both end of the bearing kudzivirira kuumbwa kweaxial current yeablative bearing or bearing bush.Pasi kabhoni bhurashi uchishandisa muenzaniso mumajenareta mahombe, chigaro chinokonzeresa chinoguma chine insulation (iyo inotakura insulation), padivi remhepo shaft hombe inogadzika kabhoni bhurashi, nekuda kwekugadziriswa kwakasiyana-siyana uye rotor yejenareta excitation kuyerwa kwevhu rekudzivirira kuri kugamuchira. the steam side of carbon brush shaft, kana rotor ichitenderera pane rotor iron core leakage, excitation the positive or negative ground pachava ne grounding voltage, Zvinoratidza kuti rotor yakanganisa uye inofanira kuvharwa kuitira kugadzirisa.Grounding bhurashi inowanzobatanidzwa kune rotor insulation yekutarisa loop, yazvino kuyerera nguva yekuzivisa chiratidzo chealarm.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. yakavambwa muna 2006, inogadzira dhiziri jenareta muChina, iyo inobatanidza dhizaini, kugovera, kutumira uye kugadzirisa dhiziri jenareta.Chigadzirwa chinofukidza Cummins, Perkins, Volvo, Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai etc. nesimba siyana 20kw-3000kw, uye vave yavo OEM fekitari uye michina centre.
