Tsohon kwaikwayo a motar Synchronous

Synchronous Motor da Hunting

Abubuwan da ake Sani:

• Hunting ta Baka: Hunting a cikin motori mai tsari shine matsalolin da rotorin yake kawo da wuya don halayen inganci a kan tafkin lafiya.

• Sabonin Hunting: Hunting zai iya shafi da halayen inganci a kan tafki, halayen rarrabe jeriyar lafiya, tafki na jihohin lafiya, ko kuma abun uban a kan tafki.

• Tattalin Hunting: Wannan matsaloli zai iya haɗa da motorin ya gama tsarin, haɗa da zafi mai girma, karɓe lafiya, da kuma sakiyar harshen tafki.

• Yadda a Kiyaye Hunting: Don kiyaye hunting, ake amfani da damper windings don kawo da slip na rotor da kuma fadada flywheels don haɗa da kalmomin rotor.

• Tsarin Synchronous Motor: Fahimtar tsarin da dama na synchronous motors yana taimakawa a zaba tsarin motor da za a yi don kiyaye tattalin hunting.

A nan ne nuna sunan "HUNTING" a cikin hanyoyin da ake yi game da motori mai tsari. Yana bayyana yadda rotorin yake ci gaba don wani matsalolin da ke faruwa saboda halayen inganci a kan tafki. Wannan matsaloli shine hunting a cikin motori mai tsari. A bincika kungiyar motori mai tsari.

Kungiyar motori mai tsari shine kungiya da ake faruwa inda lafiyar electromagnetic ita ce da kuma lafiyar tafki. A kungiyar, rotorin yake tafiya da kalmomi mai tsari don haɗa da kalmomin torque angle (δ). Idan an samu halayen inganci a kan tafki, kungiyar zai faruwa da kuma lafiyar da yake kawo da kalmomin motori.

Me Ta Ci Gaba Hunting?

Motori mai tsari da ba ake tafki ba yake faruwa da load angle na zero. Idan tafki na shaft yake faruwa, load angle na yake faruwa. Idan an samu tafki, P1, zuwa motori da ba ake tafki ba, motorin yake faruwa da waɗanda ba ake tafki ba.

Kuma, load angle (δ) yake faruwa daga zero zuwa δ1. A farkon, lafiyar electrical power da aka faruwa take daidaita da tafki na mechanical, P1. Saboda kungiyar ba a faruwa ba, rotorin yake ci gaba zuwa δ2, tare da lafiya masu electrical power da yake faruwa da miliyan.

Rotorin yake faruwa zuwa kalmomin tsari amma ba a haɗa da shi ba, tafiya da kalmomin tsari. Wannan tafiya yake faruwa load angle, ta kawo kungiyar ba a faruwa ba.

Duk da haka, rotorin yake ci gaba ko kawo da matsalolin da ke faruwa, wannan matsaloli shine hunting ko phase swinging. Hunting yana faruwa a cikin motori mai tsari da kuma generators idan an samu halayen inganci a kan tafki.

Sabonin Hunting a Cikin Motori Mai Tsari 

1.  Halayen inganci a kan tafki.

2.  Halayen rarrabe jeriyar lafiya.

3.  Tafki na jihohin lafiya.

4.  Abun uban a kan tafki.

Tattalin Hunting a Cikin Motori Mai Tsari

1.  Zai iya haɗa da gama tsarin.

2.  Yana haɗa da zafi mai girma a kan rotor shaft.

3.  Yana faruwa karɓe lafiya da kuma sakiyar harshen tafki.

4.  Yana haɗa da surges masu current da kuma power flow.

5.  Yana faruwa amsa resonance.

Yadda a Kiyaye Hunting a Cikin Motori Mai Tsari

Dubu yadda ake amfani don kiyaye hunting. Wadannan shine –

•    Amfani da Damper Winding: Wannan shine low electrical resistance copper / aluminum brush da ake kara a slots of pole faces a cikin salient pole machine. Damper winding yana kiyaye hunting tare da lafiya mai kawo da slip na rotor. Masu damping torque yana faruwa da kalmomin slip speed.

•    Amfani da Flywheels: Prime mover yana da large and heavy flywheel. Wannan yana faruwa inertia na prime mover da kuma taimakawa a haɗa da kalmomin rotor.

•    Designing synchronous machine da synchronizing power coefficients da ma'ana.
