Maitiro ekuita Magnetize jenareta

Kana jenareta isina magineti, inogona kuitwa magineti nebhatiri re12V.Iyo chaiyo nzira ndeye: batanidza waya mbiri kubva ku + - danda rebhatiri.Vhura iyo inodzivirira iron kesi yejenereta control circuit board.Tanga jenareta.Batanidza iyo + - danda kuF + F - (yejenareta control redunhu bhodhi, uye nguva yekubatanidza haingapfuure sekondi imwe chete. Mushure memagnetization, tarisa voltage uye frequency. Ziva kuti jenareta haigone kutakurwa magineti isati yasvika. yapera, uyezve inogona kukwidzwa mushure mekunge yatariswa kuti ndeyemazuva ese.Imwe kesi ndeyekutanga jenareta uye inochaja yega mukati memaminitsi gumi.

Asi kana jenareta kurasikirwa excitation nokuda zvikanganiso matambudziko, tinofanira kurigadzirisa maererano zvikanganiso zvakasiyana.

Chii chinokonzera kurasikirwa kwejenareta kwekunakidzwa?

Panguva yekushanda kwejenereta, kunakidzwa kunongoerekana kwanyangarika zvachose kana kuti chikamu, chinonzi kurasikirwa kwekunakidzwa kwejenereta.Zvikonzero zvekurasikirwa kwejenareta kwekunakidzwa zvinogona kupfupikiswa sedunhu rakavhurika kana dunhu diki redunhu rinokurudzira, kusanganisira kutadza kweiyo exciter, excitation transformer kana excitation circuit, netsaona kubata kweexcitation switch, kuchinjika kusiri iko kwekunakidzwa kwekumirira, kurasikirwa kwesimba rekuwedzera remagetsi. excitation system, mhepo yakavhurika ye rotor winding kana excitation circuit kana yakakomba short circuit ye ​​rotor winding, kukundikana kwe semiconductor excitation system, kupisa kana kupisa rotor slip ring.

1. Excitation transformer kukanganisa rwendo kunokonzera jenareta kurasikirwa kwekunakidzwa

Nekuda kwekuremerwa kwekugadzira insulation ye transformer kana kuderera zvishoma nezvishoma kwechirema chekudzivirira panguva yekushanda, chiitiko chekubuda chinoitika, zvichikonzera kugumburwa kweiyo excitation transformer kuchengetedza chiito uye kudonha kweyuniti nekuda kwekurasikirwa kwechiitiko chekudzivirira.Matanho uye zviyero zvichaitwa zvine hungwaru, uye bvunzo dzenguva dzose, kuita uye kugadzirisa matambudziko kuchaitwa.Zvinoenderana nemirairo yakakodzera uye zviyero, kuitiswa kwe periodic bvunzo yekuisa chirango kuchaitwa nekungwarira.

2. Kunakidzwa kwekurasikirwa kwejenareta kunokonzerwa nekugumburwa kwe de excitation switch

Zvikonzero zverwendo rwe de excitation switch zvinosanganisira: (1) murairo werwendo we de excitation switch inotumirwa zvisizvo paDCS.(2) Tripping command ye deexcitation switch inotumirwa kunze kana paine chikanganiso chekuburitsa relay.(3) Kubata kwebhatani rerwendo reiyo de excitation switch pane yemagetsi vertical panel iri mukamuri yepakati yekudzora inodhonzwa kuti itumire rwendo rwekuraira.(4) Nzvimbo yekutonga yenzvimbo yekamuri yekukurudzira inoparadzanisa nemaoko de excitation switch.(5) Iyo insulation ye control circuit cable ye de excitation switch inodonha.(6) Iyo switch body inokwevera iyo de excitation switch.(7) Iyo yekumisikidza pasi kweiyo DC system inoita kuti de excitation switch ifambe.

3. Kurasikirwa kwekunakidzwa kwejenareta kunokonzerwa nekubatidzwa kwe slip ring yekusimudzira

Chikonzero chetsaona ndechekuti kudzvanywa kwekabhoni bhurashi compression chitubu kwakanga kusina kuenzana, zvichikonzera kusaenzana kwazvino kugoverwa kwemamwe mabhurashi ekabhoni, zvichikonzera kuwanda kwekabhoni mabhurashi uye kukonzera kupisa.Pamusoro pezvo, iyo kabhoni bhurashi yakasviba, ichisvibisa iyo yekubata kumeso kwekabhoni bhurashi uye inotsvedza mhete, zvichiita kuti kupikisa kwemamwe mabhurashi ekabhoni uye rin'i inotsvedza iwedzere uye yobva yapenya.Mukuwedzera, kupfekedzwa kweiyo yakanaka uye yakaipa kabhoni mabhurashi haina kuenzana, uye kupfeka kweiyo negative electrode kunogara kwakakomba kupfuura iyo yakanaka electrode.Iyo yekumusoro roughness ye slip ring inowedzerwa nekuda kwekupfeka kwakakomba, uye inotsvedza mhete yemoto inokonzerwa nekuda kwekutadza kudzora nenguva.

4. Kurasikirwa kwekunakidzwa kwejenereta kunokonzerwa nekugadzika kweDC system

Mushure meiyo yakanaka electrode kugadzika kweiyo DC system, tambo refu yakagovera capacitance, uye voltage pamigumo yese yecapacitance haigone kushanduka kamwe kamwe, izvo zvinoita kuti capacitance ikozvino yetambo refu mumhepo yekunze yekutsika kwejenareta deexcitation switch to. inoyerera nepakati pepakati relay pane yekunze rwendo rwekubuda, uye relay inoita kutsika jenareta deexcitation switch, zvichikonzera kudonha kwejenareta deexcitation kudzivirira chiito.

5. Kurasikirwa kwekunakidzwa kwejenereta kunokonzerwa nekukanganisa kwekugadzirisa hurongwa hwekugadzirisa

Mhosva yebhodhi reEGC rejenareta excitation system regulator yakakonzera iyo over-voltage protection action ye rotor ye generator excitation regulator, zvichikonzera kugumburwa kwekurasikirwa kwechiito chekudzivirira.
