Waa maxay sababta uu Generator-ku u dejiyo curiyaha usha hadda

Xaaladaha caadiga ah, caabbinta dahaarka ee qaybta wareega ee koronto-dhaliyaha dhulka loo dhigay ayaa looga baahan yahay inay ka weyn tahay 0.5m Ω.Haddii labada daraf ee usheeda dhexe ay isku mar dhulka dhigaan, hadda shaft-ga ayaa la dhalin karaa.Isha hadda socota waxay dhaawac weyn u geysataa koronto-dhaliyaha oo leh wareeg hawleed dheer.Haddii aan la helin wakhti dheer, waxay keeni doontaa dhaawac halis ah qaybaha farsamada ee qalabka koronto-dhaliyaha.Waa maxay sababta dab-dhaliye ma dhalisaa usheeda dhexe?

Sababtu waa sida soo socota:

Marka qalabka matoorku uu yahay rotor-ka mootada, sababta inta badan waxaa keena qaybinta asymmetric ee xadadka magnetic xoogga iyo saamaynta magnetization ee shafka wareega.Qaybinta asymmetric ee xadadka birlabeedka xoogga badanaa waxaa sababa asymmetry ee farqiga lamination.

Waxa kale oo jirta ifafaale ah in shaft current uu ka dhashay isticmaalka awooda dibadeed.Sababta ayaa ah in goobta magnetic wareega ee unugga mootooyinka guurguura ay gooyaan kaariyaha ama rotor-ka aan dheelitirnayn, taas oo keenta magnetization ee shafka wareega.Qallafsanaanta, fiyuuska, isku dhaca iyo aaladaha hadda jira ee qallafsan ayaa sababi kara birlabnimada qalabka oo ay abuuraan goob birlab ah.

Marka goobta birlababka ah ee wareegtadu ay gooyso kaariyaha, qaybahan ayaa keeni doona awood gaar ah.Marka awooddu kor u kacdo oo ku filan inay jebiso filimka saliidda, wareegga hadda ayaa la samayn doonaa.Wareeggan hadda socda waxa laga yaabaa inuu dhex maro rotor-ka oo dhan, ama waxa laga yaabaa inuu sameeyo haddal-wareeg-gaaban oo maxalli ah oo ku jira xidhmada ama shaabadda sabaynaysa.Dabeecadahani waxay iyaguna dhaliyaan dhul birlabeedyo cusub oo birlabeeya shafka ama qaybo kale.Sidaa darteed, is-beddelkan wadajirka ah ee magnetoelectricity wuxuu sameyn doonaa dhul birlab ah oo xooggan iyo hadda sare ee qalabka koronto-dhaliyaha.Danab ka keenaya usheeda dhexe hadda ee set koronto waa in ka badan 20V, iyo danab burburay waa inta u dhaxaysa 30 ~ 100V.Sidaa darteed, hubinta shaqada caadiga ah ee qalabka koronto-dhaliyaha waxay si wax ku ool ah u xaddidi kartaa tamarta qalabka koronto-dhaliyaha.Marka danabku uu ka hooseeyo 1V, shaft current lama dhalin doono.

Marka la isticmaalayo qalabka koronto-dhaliyaha, waa in aan had iyo jeer fiiro gaar ah u yeelano in hadda uu jiro shafka.Haddii la soo saaro, waa in aan waqti ku habboon falanqaynno oo ogaanno sababaha, si looga fogaado abuurista qulqulka qulqulka.

Maxaa dhacaya haddii shafka koronto dhaliyaha uu kor u kaco?

Tallaabooyinka soo socda ayaa badanaa la sameeyaa:

(1) Inta lagu jiro naqshadeynta iyo rakibidda, suufka dahaadhka ah ayaa sida caadiga ah lagu rakibaa inta u dhaxaysa taageerada xajinta iyo saldhigga dhammaadka kicinta ee koronto-dhaliyaha, iyo tallaabooyinka xakamaynta ayaa loo qaadayaa dhammaan tuubooyinka saliidda, boolal iyo boolal.

(2) Si looga hortago danab usheeda dhexe uu keeno hal dhibic grounding wareegga gaaban ee dabaylaha rotor, gelin qalabka ilaalinta grounding laba-dhibcood ee wareegga excitation galay.

(3) Si loo gooyo qulqulka qulqulka, dhinaca exciter waxaa ka mid ah koronto-dhaliyaha, shaabadda saliidda ee koronto-dhaliyaha, taageeridda marin-biyoodka iyo ka-soo-baxa biyaha iyo qulqulka biyaha ee tubooyinka dhaliye biyo qaboojiye rotor, iyo suufka dahaadhka ah ayaa lagu rakibay inta u dhaxaysa xajinta exciter iyo kaaliyaha iyo saxanka saldhiga ee saldhiga.Xidhiidhiyayaasha tubbada xadhkaha iyo tuubada saliidda ee ku xidhan barxadda xajinta waa in sidoo kale laga dahaadhay xajinta, waxaana la qaadan karaa tillaabooyinka ilaalinta laba-lakabka ah.

(4) Ka fogow asymmetry wareegga magnetic ee naqshadeynta mootada.

(5) Qulqulka magnetic axial waa in laga fogaadaa inta lagu jiro naqshadeynta, soo saarista iyo hawlgalka matoorka.

(6) Ka dahaadh dhulka korkiisa.

(7) Ku rakib buraashka dhulka hoostiisa ku yaal shafka.

(8) Qabo baabuurka xadhkaha bini'aadamka ama gariiradda dheeraadka ah.

(9) Ku dar capacitor-ka-dhaafka dhulka ee meesha cudud ee ka baxa mashiinka DC-ga.
