Yintoni ebangela iGenereyitha phantsi kweVoltage

Ijenereyitha sisixhobo somatshini esiguqula ezinye iintlobo zamandla zibe ngamandla ombane.Iqhutywa yiijini yamanzi, i-injini yomphunga, i-injini ye-diesel okanye abanye oomatshini bamandla, kwaye iguqula amandla aveliswa kukuhamba kwamanzi, ukuhamba komoya, ukutsha kwamafutha okanye i-nuclear fission ibe ngamandla oomatshini kwaye iwagqithisele kwijenereyitha.Iguqulelwe kumbane ngejenereyitha.Iijenereyitha zisetyenziswa ngokubanzi kwimveliso yezoshishino kunye nezolimo, ukukhusela isizwe, isayensi kunye neteknoloji kunye nobomi bemihla ngemihla.

Kukho iindlela ezininzi zoku iijenereyitha , kodwa imigaqo yabo yokusebenza isekelwe kumthetho we-electromagnetic induction kunye nomthetho wamandla ombane.Ke ngoko, umgaqo jikelele wolwakhiwo lwayo kukuba: sebenzisa izixhobo ezifanelekileyo zemagneti kunye neziqhubayo ukwenza iisekethe zemagnethi kunye neesekethe ezenza i-electromagnetic induction kunye nomnye ukuvelisa amandla ombane kunye nokufezekisa injongo yokuguqula amandla.

Yintoni ebangela ukuba ijenereyitha iphantsi kombane?

(1) Isantya se-prime mover siphantsi kakhulu.

(2) Ukuxhatshazwa kwesiphaluka sokuvuselela kukhulu kakhulu

(3) Ibrashi ye-exciter ayikho kwindawo engathathi hlangothi, okanye uxinzelelo lwentwasahlobo luncinci kakhulu.

(4) Ezinye iidiode zokulungisa ziyaqhekeka.

(5) Kukho isiphaluka esifutshane okanye impazamo yomhlaba kwi-stator winding okanye i-excitation winding.

(6) Umphezulu wokudibanisa webrashi uncinci kakhulu, uxinzelelo alwanelanga, kwaye uqhagamshelwano lubi.Ukuba ibangelwa ngumphezulu we-commutator, unokupholisa umphezulu we-commutator nge-emery cloth ngesantya esiphantsi, okanye ulungise uxinzelelo lwasentwasahlobo.

Ngenxa yezi zizathu zingasentla, indlela yokunyusa amandla ombane wejeneretha?

1. Lungisa isantya se-prime mover kwixabiso elilinganisiweyo.

2. Ukunciphisa ukuchasana kwe-rheostat yamagnetic field ukunyusa i-excitation current.Kwiijenereyitha zokuvuselela i-semiconductor, khangela ukuba ii-joints ezongezelelweyo zomoya zivaliwe okanye zixhunyiwe ngokungalunganga.

3. Lungisa ibrashi kwindawo echanekileyo, buyisela ibrashi, ulungise uxinzelelo lwentwasahlobo.

4. Jonga kwaye ubuyisele i-diode yokuphazamiseka.

5. Khangela impazamo kwaye uyisuse.

Ezinye iindlela zokunyusa amandla ombane wejeneretha:

Ukwandisa ubunzima bokuvuselela ijenereyitha;

ukwandisa isantya sejeneretha;

Ukunciphisa ukuchasana kwesiphaluka kwi-generator;

Ukukhanya komthwalo okanye ubuninzi bokuvuselela ukwanda njengoko umthwalo ukhula.

Uyigcina njani i-terminal voltage ye-generator ingatshintshwanga

Xa umthamo wangoku wejeneretha utshintsha, ngokwendlela yeempawu zangaphandle, i-terminal voltage ye-generator iya kutshintsha nayo.

Ukuze ugcine i-terminal voltage ye-generator rhoqo, i-excitation current ye-generator kufuneka ilungiswe ngokufanelekileyo.

Ngaphantsi kwemeko yokugcina isantya, amandla omthwalo kunye ne-voltage ye-terminal ingatshintshwanga, ubudlelwane phakathi kwe-IL yangoku yokuvuselela kunye nomthwalo we-ls ubizwa ngokuba luphawu lolawulo lwejeneretha.

Kwimithwalo enqabileyo kunye ne-inductive, njengoko umthwalo wangoku usanda, i-voltage ye-terminal yejeneretha iya kuncipha ngokuthe ngcembe.Ukugcina i-terminal voltage ingatshintshwanga, umsinga wovuselelo kufuneka wonyuswe ngokufanelekileyo ukubuyisela ukukhutshwa kweemagnethi kunye nokuvuza kokusabela kwe-armature.ukwehla koxinzelelo.

Kwimithwalo ye-capacitive, ekubeni i-terminal voltage ye-generator iya kunyuka ngokunyuka komthwalo wangoku, umsinga wokuvuselela kufuneka uncitshiswe ukuze unciphise umphumo wokuvuselela i-armature reaction kunye nesiphumo sokunyusa ukusabela kokuvuza, ukuze kugcinwe i-terminal voltage.rhoqo.

Iingxaki ezimele ziqwalaselwe xa zihambelana nejeneretha engenamthwalo kunye negridi yamandla: ngexesha lokutshintsha kunye nokuvala, i-generator akufanele ibe ne-inrush current eyingozi, kwaye i-shaft ejikelezayo ayifanele ifakwe ngokukhawuleza.

Emva kokuvala, i-rotor kufuneka ikwazi ukutsalwa kwi-synchronization ngokukhawuleza (oko kukuthi, isantya se-rotor silingana nesantya esilinganisiweyo).Ngenxa yesi sizathu, ijeneretha ehambelanayo kufuneka ihlangabezane nale miqathango ilandelayo:

1. Ixabiso elisebenzayo le amandla ombane wejeneretha kufuneka ilingane nexabiso elisebenzayo legridi yombane.

2. Isigaba sombane wejeneretha kunye nesigaba sombane wegridi kufuneka sibe yinto enye.

3. I-frequency ye-generator ilingana ne-frequency yegridi.

4. Ukulandelelana kwesigaba sombane wejeneretha kuhambelana nokulandelelana kwesigaba sombane wegridi.

5. Akuvumelekanga ngokungqongqo ukuthumela umbane kwigridi yamandla.
