Jenareta huru kudzivirira uye kuchengetedza kuchengetedza

Mhando dzakasiyana dzejenareta dzine dziviriro dzakasiyana.Semuyenzaniso, 30MW jenareta dziviriro ine: mutsauko, nguva inogumira kutyora kwazvino, komboni voltage pamusoro pezvino, kurasikirwa kwemagineti, kuwandisa kwekufamba.Kupisa kwakanyanya, kuwandisa, single-phase grounding alarm.

1, kuchengetedzwa kukuru kwejenareta: shandura musiyano weboka (musiyano wakakura), musiyano wejenareta (musiyano), jenareta transverse musiyano.

(1) Longitudinal mutsauko kudzivirira..

(2) kutenderedza pfupi dunhu kudzivirira.

a.Stator winding single-phase grounding protection.

b, rotor winding grounding protection.
c, jenareta magineti kurasikirwa kudzivirira.

2, jenareta kuchengetedza kuchengetedza: kutadza kutanga (svetuka kudzivirira kweiyo yepamusoro level switch).

Zvinoreva: Kana chiito chekudzivirira jenareta, mhedzisiro ndeyekuti kudzivirira kwejenareta kana switch inorambwa, haikwanise kutsika kumira.Saka kuti utange jenareta padyo nechikamu chekudzivirira, svetuka kubva padivi pechikamu switch.Semuenzaniso: jenareta ine mutsara, jenareta haina kusvetuka, kunonoka kusvetuka mutsara wekuchinja.

A. Stator winding overcurrent protection inokonzerwa nekunze short circuit.

b.Stator winding overload protection.

c.Rotor mhepo.

d, rotor pamusoro overload kudzivirira.

e.Stator winding overvoltage protection.

f.Inverse kudzivirira simba.

g.Kunze-kwenhanho kudzivirira.

h.Kunyanya-excitation kudzivirira.
ini, low frequency dziviriro.

3. Jenareta,

yakagadzirwa naFaraday musi waGunyana 23, 1831, imota inoshandura simba remagetsi kuita simba remagetsi.Inowanzo kufambiswa nemhepo inoputika, turbine yemvura kana injini yekupisa mukati.Simba remagetsi nderimwe remasimba anonyanya kukosha munharaunda yemazuva ano.Majenareta anoshandiswa zvakanyanya mukugadzirwa kwemaindasitiri nekurima, kudzivirira kwenyika, sainzi uye tekinoroji uye hupenyu hwezuva nezuva.Majenareta akakamurwa kuita DC jenareta uye AC jenareta.Iyo yekupedzisira inogona kukamurwa kuita synchronous jenareta uye asynchronous jenareta marudzi maviri.Rudzi rwakajairika rwechimanjemanje chiteshi chemagetsi ndiyo synchronous jenareta.
