Wani Phase Sequence Indicator?

Mai yadda ake sani Phase Sequence Indicator?

Takardun Phase Sequence Indicator

Phase Sequence Indicator shine taurari na iya bayyana takarda masu jiki uku na bincike.

Abubuwa da Indicators

Akawo biyu ne—na turanci da na kusa, kowane ta na tsohon addinin da ya yi aiki.

Tsohon Addin da Turanci Ya Yi Aiki

Ya yi aiki da tsohon addinin motoci. A nan, mafashin ya fi kan darajar star, kuma abokin bincike ya ba shi daga kamar RYB da aka nuna a cikin rasa. Idan an ba shi bincike, za su fa karamin magana mai tsirra, kuma wannan karamin magana mai tsirra za su fa eddy EMF a cikin discin aluminium mai karfi da aka nuna a cikin rasa.

Eddy EMF ya fa eddy current a cikin discin aluminium, wanda suka gudanar da karamin magana mai tsirra don haɗa torque, wanda ya ci discin. Idan discin ya ci zuwa hagu, takarda ta zai RYB; idan ya ci zuwa hagu na musamman, takarda ta zai karkashin.

Tsohon Addin da Kusa Ya Yi Aiki

A nan ne abubuwan da ake sa static type indicator:

Idan takarda ta zai RYB, lamp B zai ci girma daga lamp A, kuma idan takarda ta karkashin, lamp A zai ci girma daga lamp B. Tana da neman cewa wannan ya faru.

A nan ne ne tunan yi amfani da takarda RYB. Ba ni suna marka voltages Vry, Vyb da Vbr kamar da cikin rasa. Muna yi amfani da balance operation haka cewa Vry=Vbr=Vyb=V.

Saboda sumar phase currents ta zai kasance, domin da muna iya rubuta I r da Iy equals to 0.27.

Wannan na nufin cewa voltage across lamp A zai kasance 27 percent daga voltage da ke cikin lamp B. Saboda haka, muna iya ƙara cewa lamp A zai ci dimmer a cikin takarda RYB, kuma a cikin takarda karkashin, lamp B zai ci dimmer daga lamp A.

Wata Phase Inductor na iya yi aiki sabon hakan, amma ya yi amfani da capacitor instead of inductor, kamar da aka nuna a cikin rasa.

Biyo neon lamps ne da amfani, tare da series resistor biyu don haɗa current da kuma da inganta neon lamp daga breakdown voltage. A nan, idan supply phase sequence ta zai RYB, lamp A zai ci, kuma lamp B ba zai ci, kuma idan takarda ta karkashin, lamp A ba zai ci, kuma lamp B zai ci.

Bayyana Takarda Masu Jiki Uku

Wadannan indicators sun taimakawa wajen samun cewa takarda ta zai RYB ko karkashin, wanda yake muhimmanci don aiki daidai na three-phase systems.
