Generator lub ntsiab tiv thaiv thiab kev tiv thaiv thaub qab

Ntau hom tshuab hluav taws xob muaj kev tiv thaiv sib txawv.Piv txwv li, 30MW generator tiv thaiv muaj: sib txawv, lub sij hawm txwv tam sim no tawg, compound voltage tshaj tam sim no, poob ntawm hlau nplaum, overvoltage mus txawv tebchaws.Kub kub, overload, ib-theem grounding tswb.

1, lub tshuab hluav taws xob tiv thaiv tseem ceeb: hloov pab pawg sib txawv (qhov sib txawv loj), lub tshuab hluav taws xob sib txawv (differential), generator transverse sib txawv.

(1) Longitudinal sib txawv tiv thaiv ..

(2) cuam tshuam kev tiv thaiv luv luv.

a.Stator winding ib-theem grounding tiv thaiv.

b, rotor winding grounding tiv thaiv.
c, lub tshuab hluav taws xob sib nqus tiv thaiv.

2, generator thaub qab tiv thaiv: tsis ua hauj lwm pib (dhia kev tiv thaiv ntawm qib siab hloov).

Lub ntsiab lus: Thaum lub tshuab hluav taws xob tiv thaiv kev ua haujlwm, qhov tshwm sim yog tias lub tshuab hluav taws xob tiv thaiv lossis hloov hluav taws xob raug tso tseg, tsis tuaj yeem nres.Yog li txhawm rau pib lub tshuab hluav taws xob uas nyob ib sab tiv thaiv, dhia tawm ntawm qhov sib txuas sib txuas.Piv txwv li: lub tshuab hluav taws xob nrog ib txoj kab, lub tshuab hluav taws xob tsis dhia, ncua mus dhia kab hloov.

A. Stator winding overcurrent tiv thaiv los ntawm sab nraud luv luv Circuit Court.

b.Stator winding overload tiv thaiv.

c.Rotor winding.

d, rotor nto tiv thaiv overload.

e.Stator winding overvoltage tiv thaiv.

f.Inverse zog tiv thaiv.

g.Kev tiv thaiv tawm ntawm cov kauj ruam.

h.Kev tiv thaiv over-excitation.
i, kev tiv thaiv tsawg zaus.

3. Generator,

tsim los ntawm Faraday thaum lub Cuaj Hlis 23, 1831, yog lub cev muaj zog uas hloov cov tshuab hluav taws xob rau hauv hluav taws xob.Nws feem ntau yog tsav los ntawm chav turbine, dej turbine lossis lub cav combustion sab hauv.Lub zog hluav taws xob yog ib qho tseem ceeb tshaj plaws ntawm lub zog hauv lub neej niaj hnub.Cov tshuab hluav taws xob tau siv dav hauv kev lag luam thiab kev ua liaj ua teb, kev tiv thaiv hauv tebchaws, kev tshawb fawb thiab thev naus laus zis thiab lub neej niaj hnub.Generators muab faib ua DC generators thiab AC generators.Cov tom kawg tuaj yeem muab faib ua synchronous generator thiab asynchronous generator ob yam.Hom kev siv hluav taws xob niaj hnub no feem ntau yog lub tshuab hluav taws xob synchronous.
