Cov Ntsiab Cai Ua Haujlwm Ntawm Txhuam Txhuam Thiab Txhuam Txhuam Txhuam Txhuam Hniav

Nyob zoo txhua tus, tsis yog peb feem ntau hnov ​​​​cov neeg muag khoom siv hluav taws xob diesel pom zoo ob hom: brushed generators thiab brushless generators? Yog li, qhov txawv ntawm ob qho tib si yog dab tsi? Lawv txoj haujlwm ua haujlwm yog dab tsi? Niaj hnub no, cov ntsiab lus no yuav piav qhia rau koj kom meej, kom txawm tias cov uas tsis muaj kev paub dhau los tuaj yeem nkag siab.

 

 

Ⅰ. Brushed Generator (Brushed Excitation)

Core: Carbon txhuam thiab npliag rings, mechanical contact rau muab excitation tam sim no.

 

1. Excitation fais fab mov:Lub AVR (Tsis Siv Neeg Voltage Regulator) xa DC tam sim no los ntawm cov pa roj carbon txhuam → plam rings rau hauv lub rotor excitation winding, tsim ib qho chaw sib nqus hauv lub rotor.

 

2. Mechanical zog→ Sib nqus zog: Lub zog tseem ceeb (lub cav diesel / roj av cav) tsav lub rotor kom tig, tsim ib qho chaw sib nqus sib nqus.

 

 

3. Sib nqus zog→ Hluav taws xob hluav taws xob: Lub teb sib nqus rotating txiav los ntawm stator peb -theem windings, thiab electromagnetic induction generates peb -theem alternating tam sim no, uas yog tso zis rau lub load.

 

4. Voltage stabilization:AVR kho qhov excitation tam sim no raws li cov zis voltage, stabilizing lub magnetic teb lub zog thiab tuav ib tug tas li tso zis voltage.

 

 

Cov ntsiab lus tseem ceeb:Lub excitation winding yog nyob rau ntawm lub rotor thiab yog ua los ntawm cov pa roj carbon txhuam thiab nplawm rings; tus qauv yog qhov yooj yim thiab tsis tshua muaj nqi -, tab sis cov txhuam hniav yog qhov yooj yim rau hnav, tsim cov nplaim taws, thiab xav tau kev saib xyuas tsis tu ncua.

 

Ⅱ. Brushless Generator (Brushless Excitation)

 

Core: Carbon brushless plam nplhaib, siv ib qho exciter thiab tig rectifier rau excitation.

Lub tshuab hluav taws xob tseem ceeb thiab exciter yog cov tshuab cais, co-axially rotating yam tsis muaj kev sib cuag.

 

1. Thaum pib excitation:Lub rotor qhov seem hlau nplaum induces ib tug me me residual voltage nyob rau hauv lub ntsiab generator stator, thiab AVR pib ua hauj lwm.

 

2. Exciter generates hwj chim:AVR xa DC mus rau exciter lub stator windings los tsim ib qho chaw sib nqus tas li; lub exciter rotor (co-}axial) txiav los ntawm magnetic teb, ua nruab nrab- zaus AC.

 

3. Rotating rectification:Lub alternating tam sim no los ntawm lub excitation generator rotor yog hloov mus rau hauv ncaj qha tam sim no los ntawm ib tug coaxial rotating rectifier (diode) thiab ncaj qha nkag mus rau lub ntsiab generator rotor excitation winding (brushless).

 

4. Main generator hluav taws xob tsim:Lub ntsiab generator rotor tsim muaj zog rotating magnetic teb, uas txiav los ntawm lub ntsiab generator stator winding thiab induces ib tug ruaj khov peb -theem alternating tam sim no tso zis.

 

5. Kaw- txoj cai vojvoog voltage:AVR saib xyuas qhov tso zis hluav taws xob hauv lub sijhawm tiag tiag thiab hloov kho lub zog ntawm stator tam sim no ntawm exciter kom ruaj khov rau lub tshuab hluav taws xob tseem ceeb.

 

Cov ntsiab lus tseem ceeb:Tshem tawm cov pa roj carbon txhuam cov nplhaib, ua rau tsis muaj hnav, tsis muaj qhov ci, cuam tshuam tsawg, thiab kev saib xyuas- ua haujlwm dawb; cov qauv yog me ntsis nyuaj thiab tus nqi yog me ntsis siab dua, ua rau nws haum rau ntev - lub sij hawm ua hauj lwm tas mus li (xws li nyob rau hauv fais fab nroj tsuag thiab nkoj).

 

Cia peb qhia cov ntsiab lus tseem ceeb ntawm no rau txhua tus:

✅ Brushed generator:ua hluav taws xob los ntawm kev sib txhuam ntawm cov pa roj carbon txhuam thiab lub nplhaib ntiv nplhaib. Cov qauv yooj yim, tab sis cov txhuam hniav txhuam tau yooj yim thiab xav tau hloov tsis tu ncua.

✅ Brushless generator:ua hluav taws xob tsis muaj kev sib cuag los ntawm electromagnetic induction. Tsis muaj qhov hnav tau yooj yim, qis dua tus nqi, thiab lub neej ntev dua.

 

Tam sim no koj tuaj yeem qhia cov qauv kev ua haujlwm ntawm ob hom tshuab hluav taws xob sib nrug! Yog tias koj pom qhov no muaj txiaj ntsig, muab nws nyiam, txuag nws, thiab qhia tawm hauv cov lus pom lub tshuab hluav taws xob uas koj tau siv!
