Ungawenza Kanjani Ijeneretha

Uma ijeneretha ingenawo uzibuthe, ingenziwa uzibuthe ngebhethri engu-12V.Indlela ethize yilena: xhuma izintambo ezimbili ku-+ - pole yebhethri.Vula ikesi lensimbi elivikelayo lebhodi lesifunda sokulawula i-generator.Qala ijeneretha.Xhuma i-+ - pole ku-F + F - (yebhodi lesekethe yokulawula ijeneretha, futhi isikhathi sokuxhuma ngeke sidlule umzuzwana owodwa. Ngemva kokusebenza uzibuthe, hlola i-voltage nefrikhwensi. Qaphela ukuthi ijeneretha ayikwazi ukulayishwa ngaphambi kokuthi kufakwe uzibuthe. iqediwe, bese ingalayishwa ngemva kokuhlolwa ukuthi ijwayelekile.Elinye ikesi ukuqala ijeneretha futhi izoshaja ngokuzenzakalelayo emizuzwini eyishumi.

Kodwa uma i-generator ilahlekelwa injabulo ngenxa yezinkinga zamaphutha, kufanele sikuxazulule ngokusho kwamaphutha ahlukene.

Iyini imbangela yokulahleka kwejeneretha ye-excitation?

Ngesikhathi sokusebenza okuvamile kwe-generator, ukuvuswa kuyanyamalala ngokuzumayo ngokuphelele noma ingxenye, okubizwa ngokuthi ukulahlekelwa kwe-excitation ye-generator.Izimbangela zokulahleka kwejeneretha ye-excitation ngokuvamile zingafingqwa njengesekhethi evulekile noma isifunda esifushane sesekhethi ye-excitation, okuhlanganisa ukwehluleka kwe-exciter, i-excitation transformer noma i-excitation circuit, ukuthinta ngephutha switch ye-excitation, ukushintsha okungalungile kwe-excitation ebekwe eceleni, ukulahlekelwa amandla asizayo isistimu yokuthakasela, isifunda esivulekile se-rotor winding noma i-excitation circuit noma isifunda esifushane esingathí sina sokujika kwe-rotor, ukwehluleka kwesistimu ye-semiconductor excitation, ukuvutha noma ukushiswa kwe-rotor slip ring.

1. Uhambo lwephutha lwe-excitation transformer lubangela ukulahleka kwejeneretha kwesasasa

Ngenxa yesici sokukhiqiza i-insulation ye-transformer noma ukuwohloka kancane kancane kwe-insulation defect ngesikhathi sokusebenza, okwenzekayo okuphumayo kwenzeka, okuholela ekukhubekeni kwesenzo sokuvikela i-excitation transformer kanye nokukhubeka kweyunithi ngenxa yokulahlekelwa isenzo sokuvikela ukuvusa.Izinqubo namazinga azosetshenziswa ngokuqinile, futhi ukuhlolwa okujwayelekile, ukuqaliswa kanye nokuxazulula izinkinga kuzokwenziwa.Ngokwemithethonqubo kanye namazinga afanele, ukuqaliswa kokuhlolwa kwezikhathi ezithile kokuqondisa kwe-insulation kuzokwenziwa ngokucophelela.

2. Ukulahlekelwa okujabulisayo kwejeneretha okubangelwa ukukhubeka kweswishi ye-de excitation

Izizathu zohambo lweswishi ye-de excitation zihlanganisa: (1) umyalo wohambo weswishi ye-de excitation uthunyelwe ngephutha ku-DCS.(2) Umyalo wokuhamba weswishi ye-deexcitation uthunyelwa uma kunephutha lokudluliswa kwe-outlet.(3) Ukuthintana kwenkinobho yohambo yeswishi ye-de excitation kuphaneli kagesi emile egunjini lokulawula elimaphakathi kukhishwa ukuze kuthunyelwe umyalo wohambo.(4) Iphaneli yokulawula yendawo yegumbi lokuvusa ihlukanisa ngesandla iswishi ye-de excitation.(5) I-insulation yekhebula yesekethe yokulawula yeswishi ye-de excitation iyehla.(6) Umzimba weswishi ukhuba iswishi ye-de excitation.(7) Ukuzinza ngokushesha kwesistimu ye-DC kubangela ukushintshwa kwe-de excitation kuhambe.

3. Ukulahlekelwa yi-excitation ye-generator okubangelwa ukushiswa kwe-excitation slip ring

Imbangela yengozi ukuthi ingcindezi ye-carbon brush compression spring ibingalingani, okuholele ekusabalaliseni okungalingani kwamanje kwamanye amabhulashi ekhabhoni, okuholele ekutheni kube namandla amabhulashi ekhabhoni ngamanye futhi kubangele ukushisa.Ngaphezu kwalokho, ibhulashi lekhabhoni lingcolile, lingcolisa indawo yokuxhumana yebhulashi lekhabhoni kanye nendandatho eshelelayo, okubangela ukumelana nokuxhumana kwamanye amabhulashi ekhabhoni kanye nendandatho yokushelela kukhule bese izinhlansi.Ukwengeza, ukugqokwa kwamabhulashi ekhabhoni e-positive kanye ne-negative akulingani, futhi ukugqokwa kwe-electrode engalungile kuhlala kubi kakhulu kunaleyo ye-electrode eqondile.Ubulukhuni bendandatho yokushelela buyanda ngenxa yokuguga okungathi sína, futhi umlilo wendandatho yokushelela ubangelwa ukwehluleka ukulawula ngesikhathi.

4. Ukulahlekelwa yi-excitation ye-generator okubangelwa ukumiswa kwesistimu ye-DC

Ngemuva kokumiswa kwe-electrode enhle yesistimu ye-DC, ikhebula ende lisabalalise amandla, futhi i-voltage emikhawulweni yomibili ye-capacitance ayikwazi ukushintsha ngokuzumayo, okubangela amandla wamanje wekhebula ende kumjikelezo wangaphandle wokukhubeka we-generator deexcitation switch to igeleza endaweni edluliselweyo emaphakathi endaweni yokukhubeka yangaphandle, futhi i-relay isebenza ukukhuba inkinobho yokuqeda amandla ejeneretha, okuholela ekukhubekeni kwesenzo sokuvikela ukukhishwa kwejeneretha.

5. Ukulahlekelwa yi-excitation ye-generator okubangelwa iphutha lesistimu yokulawula i-excitation

Iphutha lebhodi ye-EGC yesilawuli sesistimu yokuvusa ijeneretha libangele isenzo sokuvikela i-over-voltage yerotha yesilawuli sokuvusa ijeneretha, okuholele ekukhubekeni kokulahlekelwa yisenzo sokuvikela ukuvusa inkanuko.
