Amsa da yin karamin kwayoyi a jeneratada a lokacin gaji? Idan ana, yana wani sababba?

A cikin lokacin da fitaccen jeneratoci, zan iya tafi kan wani alama ta "karamin ruwa" amma wannan ya kamata yana nufin karamin electromotive force (Back EMF) wanda ke faru a lokacin fitaccen, ba karamin ruwa na gaba. Wannan bayyana hakan da kuma yadda:

Back EMF (electromotive force)

A lokacin da jeneratoci ya faru, rotorocin ya faru zuwa. Daga rike Faraday na electromagnetic induction, idan rotoroci ya kada masu shirya a windings na stator, za a samu electromotive force na biyu a windings. Yadda mai guje na electromotive force na biyu ya faru ya kula da yadda rotoroci ya faru zuwa da kuma yadda masu shirya. Idan yadda rotoroci ya faru zuwa bai yi mafi muhimmanci da yadda ake sanar da shi, zan iya tafi kan back EMF a lokacin fitaccen.

Bayyana sababbin

• Yadda rotoroci ya faru zuwa: A lokacin fitaccen, idan yadda rotoroci ya faru zuwa bai yi mafi muhimmanci da yadda masu shirya a stator winding, za a samu electromotive force na biyu.

• Kudan masu shirya: A lokacin fitaccen, masu shirya a cikin jeneratoci bai kasance suka kadan, don haka yadda electromotive force na biyu ya faru za a iya kasance daidai da yadda ake sanar da shi.

• Excitation system: Don jeneratoci na tsari, yadda excitation system ya faru zuwa za a iya tabbatar da yadda electromotive force na biyu ya faru. Idan excitation system bai ya faru zuwa a lokacin da yake, zan iya samun karamin electromotive force na biyu na lokacin da yake.

Karamin ruwa

Karamin ruwa na gaba yana nufin karamin ruwa a matsayin da ba a gaba da inda jeneratoci ya faru. Wannan ba zai faru a lokacin fitaccen ba, idan ba a nan ne wani abu da ke faru a cikin system ko wani abu da ke faru a cikin design. Wadannan ne abubuwa da za su iya samun karamin ruwa:

• Babu fitaccen: Idan jeneratoci bai faru zuwa a gaba, za a iya ba da electromotive force da ya saurara karamin ruwa, amma za a iya samun karamin ruwa daga load ko wadannan sources na karamin ruwa zuwa jeneratoci.

• Control system failure: Idan control system bai ya faru zuwa da kasa ko bai ya faru zuwa, yadda karamin ruwa ya faru za a iya kasance daidai.

• External effects: A wasu lokaci, kamar lokacin da yanayin grid voltage ya faru zuwa, karamin ruwa za iya faru zuwa a matsayin da ba a gaba da inda.

Yadda ake bukata

• Check the starting procedure: Tambayata cewa yadda ake faru jeneratoci ita ce, musamman don jeneratoci na tsari, zaka iya set up excitation system daidai.

• Check the control system: tambaya cewa control system ya faru zuwa daidai da kuma cewa bai da wani abu da ke faru a cikin settings ko faults.

• Protective measures: Saka protective devices daidai, kamar reverse current protectors, don in ba damar equipment da ya faru a lokacin fitaccen.

• Monitoring and commissioning: Monitoring and commissioning a cikin da gaba a lokacin fitaccen don in ba daidai.

Muhimmiyar

A lokacin da jeneratoci ya faru, zan iya tafi kan back EMF ba karamin ruwa na gaba. Wannan alama ya kamata yana nufin kudan masu shirya a lokacin fitaccen ko yadda rotoroci ya faru zuwa. Karamin ruwa na gaba ba zai faru ba, amma idan ba a nan ne, zan iya samun karamin control system failure ko wadannan external factors. Proper starting procedures, control system settings, and appropriate protection measures can effectively avoid these problems.
