Zomwe Zimayambitsa Jenereta Pansi pa Voltage

Jenereta ndi chipangizo chomwe chimasintha mphamvu zamtundu wina kukhala mphamvu yamagetsi.Imayendetsedwa ndi turbine yamadzi, turbine ya nthunzi, injini ya dizilo kapena makina ena amphamvu, ndipo imatembenuza mphamvu yopangidwa ndi madzi oyenda, mpweya, kuyaka kwamafuta kapena nyukiliya kukhala mphamvu yamakina ndikuyitumiza ku jenereta.Kusinthidwa kukhala magetsi ndi jenereta.Ma jenereta amagwiritsidwa ntchito kwambiri pakupanga mafakitale ndi zaulimi, chitetezo cha dziko, sayansi ndi ukadaulo komanso moyo watsiku ndi tsiku.

Pali mitundu yambiri ya jenereta , koma mfundo zawo zogwirira ntchito zimachokera ku lamulo la electromagnetic induction ndi lamulo la electromagnetic force.Chifukwa chake, mfundo yayikulu pakumanga kwake ndi: gwiritsani ntchito zida zoyenera za maginito ndi ma conductive kupanga ma circuit maginito ndi mabwalo omwe amayendetsa ma electromagnetic induction wina ndi mnzake kuti apange mphamvu yamagetsi ndikukwaniritsa cholinga chosinthira mphamvu.

Nchiyani chimayambitsa jenereta pansi pa voteji?

(1) Kuthamanga kwa prime mover ndikotsika kwambiri.

(2) Kukaniza kwa dera losangalatsa ndi lalikulu kwambiri

(3) Burashi ya exciter siimalowerera, kapena kuthamanga kwa masika ndikochepa kwambiri.

(4) Ma diode ena owongolera amawonongeka.

(5) Pali chozungulira chachifupi kapena cholakwika chapansi pamayendedwe a stator kapena mafunde osangalatsa.

(6) Malo okhudzana ndi burashi ndi ochepa kwambiri, kupanikizika sikukwanira, ndipo kukhudzana ndi koyipa.Ngati zimayambitsidwa ndi pamwamba pa commutator, mukhoza kupukuta pamwamba pa commutator ndi nsalu ya emery pa liwiro lotsika, kapena kusintha kuthamanga kwa masika.

Pazifukwa zomwe zili pamwambazi, mungawonjezere bwanji magetsi a jenereta?

1. Sinthani liwiro la prime mover kukhala mtengo wovotera.

2. Chepetsani kukana kwa maginito a rheostat kuti muwonjezere chisangalalo.Kwa majenereta osangalatsa a semiconductor, fufuzani ngati zolumikizira zowonjezerazo zalumikizidwa kapena kulumikizidwa molakwika.

3. Sinthani burashi pamalo oyenera, sinthani burashi, sinthani kuthamanga kwa masika.

4. Yang'anani ndikusintha diode yosweka.

5. Yang'anani cholakwika ndikuchichotsa.

Njira zina zowonjezera magetsi a jenereta:

Wonjezerani kulemera kwachisangalalo kwa jenereta;

kuwonjezera liwiro la jenereta;

Kuchepetsa kukana kwa dera mu jenereta;

Kupepuka kwa katundu kapena kuchuluka kwa chisangalalo kumawonjezeka pamene katundu akuwonjezeka.

Momwe mungasungire voteji ya jenereta yosasinthika

Pamene katundu panopa wa jenereta kusintha, malinga ndi khalidwe pamapindikira kunja, voteji otsiriza a jenereta kusintha ndi izo.

Kuti mphamvu yamagetsi ya jenereta ikhale yosasinthasintha, mphamvu yamagetsi ya jenereta iyenera kusinthidwa moyenera.

Pansi pa kusunga liwiro, mphamvu yamagetsi ndi magetsi osasinthika osasinthika, mgwirizano pakati pa IL yosangalatsa ya IL ndi katundu ls umatchedwa chikhalidwe cha jenereta.

Kwa katundu wotsutsa komanso wochititsa chidwi, pamene katundu akuwonjezeka, mphamvu yamagetsi ya jenereta imachepa pang'onopang'ono.Kuti mphamvu yamagetsi isasinthe, mphamvu yamagetsi iyenera kukulitsidwa molingana ndi zomwe zili ndi demagnetization ndi kutayikira kwamphamvu kwa zida.kutsika kwamphamvu.

Kwa katundu wa capacitive, popeza mphamvu yamagetsi ya jenereta idzawonjezeka ndi kuwonjezeka kwa katundu wamakono, mphamvu yamagetsi iyenera kuchepetsedwa kuti ithetse mphamvu ya mphamvu ya armature reaction ndi kulimbikitsa mphamvu ya kutayikira, kuti apitirize ma terminal voltage.mosalekeza.

Mavuto omwe amayenera kutsatiridwa pamene akufanana ndi jenereta yopanda katundu ndi gululi yamagetsi: panthawi yotsegula ndi kutseka, jenereta sayenera kukhala ndi zowonongeka zowonongeka, ndipo shaft yozungulira sayenera kugwedezeka mwadzidzidzi.

Pambuyo potseka, rotor iyenera kukokedwa mu kulunzanitsa mwamsanga (ndiko kuti, liwiro la rotor ndilofanana ndi liwiro lovotera).Pachifukwa ichi, jenereta ya synchronous iyenera kukwaniritsa zotsatirazi:

1. Mtengo wothandiza wa magetsi a jenereta iyenera kukhala yofanana ndi mtengo wamagetsi wamagetsi.

2. Gawo la magetsi a jenereta ndi gawo la magetsi a grid ayenera kukhala ofanana.

3. Mafupipafupi a jenereta ndi ofanana ndi mafupipafupi a gridi.

4. Gawo la gawo la magetsi a jenereta limagwirizana ndi ndondomeko ya gawo la grid voltage.

5. Ndizoletsedwa kutumiza magetsi ku gridi yamagetsi.
