Duk da na gina shirya karamin aiki ba tare da zahiri mai kyauwa Ga haka yadda aikin tsirrai masu layi na gina shirya karamin aiki ba?

A nan da gaba masu taimakawa na kusa, zai iya samun tsarin kasa a cikin haka:

I. Amfani da tsafta ta kasance

Kawo zabe-zaben kasa zuwa zabe-zaben mekaniki

Dalilai na tsafta na turbin ta kasa suna yawan kayan ainihi. Idan kasa ya shiga dalilai, saboda kayan ainihin dalilai da kuma tarihin aerodinamika, zabe-zaben kasa an zama zabe-zaben mekaniki na tsafta.

Misali, dalilai na turbin mai yawa suna yawan mita duka, kuma suna kayan ainihi na mafi yawa wanda take so kuɗi da kayan ainihin jirgin ruwa. Idan kasa ya shiga sana'ar da yawa, zabe-zaben kasa a dukkukan da karamin dalilai suka zama na musamman, wanda yake kawo tsafta zuwa harkar mutum.

Bayyana zabe-zaben mekaniki da tushen bayyanai

Harkar tsafta an bayyana zuwa rotor na generator tare da tushen bayyanai. Tushen bayyanai yana da muhimmiyar abubuwa kamar gear box da tushen bayyanai. Fungarmu shine kawo harkar tsafta da ke yawa da ma'adara zuwa harkar takwas da ke yawa da ma'adara na generator.

Misali, a cikin wasu turbin kasa, gear box na iya zama harkar tsafta da ke yawa da ma'adara zuwa harkar takwas da ke yawa da ma'adara na generator.

II. Tsarin amfani da generator

Samun tsarin kasa da tsafta ta electromagnetic induction

Turbin kasa suna amfani da generator asynchronous ko synchronous. A nan da gaba masu taimakawa na kusa, rotor na generator ya haifi da tsafta, kuma ya zama harkar magnetic field a winding na stator, wanda yake kawo wuce electromotive force.

Idan mutum ya yi harkar a magnetic field, wuce electromotive force ya faru a farkon mutum. A cikin turbin kasa, rotor na generator yana da kyau da mutum, kuma magnetic field a winding na stator ya faru da permanent magnets ko excitation windings.

Misali, rotor na generator asynchronous yana da kayan ainihi na squirrel-cage. Idan rotor ya haifi, conductors a rotor an zama harkar magnetic field, wanda yake kawo wuce current. Wuce current na iya kawo magnetic field a rotor, wanda yake kawo interaction da magnetic field a winding na stator, kuma yake kawo rotor zuwa harkar takwas.

Self-excitation da voltage building

A cikin wasu generator synchronous, voltage building da self-excitation ya buƙata don kawo magnetic field na farko. Self-excitation da voltage building shine kawo output voltage na generator da gaba masu taimakawa na kusa, tare da residual magnetism da armature reaction.

Idan rotor na generator ya haifi, saboda residual magnetism, wuce electromotive force mai yawa ya faru a winding na stator. Wuce electromotive force na iya shiga rectifier da regulator a tushen excitation, kuma yake kawo excitation winding, wanda yake kawo magnetic field a winding na stator zuwa yawa. Idan magnetic field ya zama, wuce electromotive force na iya zama har zuwa rated output voltage na generator.

III. Output da control

Output

Tsarin kasa na generator an bayyana zuwa grid na kasa ko local loads tare da cables. A cikin tushen bayyanai, yana buƙata transformer don kawo voltage zuwa yadda ake buƙata.

Misali, tsarin kasa na turbin mai yawa suna buƙata step-up transformer idan ba za a bayyana zuwa high-voltage power grid don tushen bayyanai mai yawa.

Control da protection

Don haka da safe da stable operation na turbin kasa, yana buƙata control da protection. Tushen control zai iya kawo angle na tsafta, harkar generator, kifas wind speed, wind direction, da output power na generator, don kawo best power generation efficiency da kuma protection na equipment.

Misali, idan wind speed ya zama, tushen control zai iya kawo angle na tsafta zuwa yadda ake buƙata don kawo force-bearing area na tsafta zuwa yawa, don haka da turbin kasa ba zama damaged by overload. Kuma tushen control zai iya monitor output voltage, current, da frequency na generator. Idan abnormal conditions ya faru, tushen control zai iya cut off power supply a baya don kawo safety na equipment da personnel.
