Ib qhov sib npaug peb-theem voltage lossis tam sim no yog ib qho uas qhov loj ntawm txhua theem yog tib yam, thiab theem kaum ntawm peb theem txawv ntawm ib leeg los ntawm 120 qib. Qhov sib npaug peb-theem network yog ib qho uas cov impedances hauv peb theem yog tib yam.

Dab tsi yog qhov sib npaug thiab tsis sib npaug hauv 3 theem system?

Ib qho tsis sib npaug 3 theem thauj khoom yog ib qho uas lub thauj khoom tsis sib npaug ntawm tag nrho peb theem. Txhawm rau kom tau txais qhov sib npaug 3 theem kev ntsuas qhov siab tshaj plaws ib theem thauj khoom yuav tsum tau muab sib npaug los ntawm 3. Ib qho kev sib npaug tsis sib npaug muab qhov tsis sib xws rau theem thiab theem rau nruab nrab voltages. FORMULA.

Vim li cas peb sib npaug 3 theem system?

In a balanced system the neutral current is zero. Li no yog tias cov khoom sib npaug, qhov tam sim no thiab qhov hluav taws xob yuav zoo ib yam txawm hais tias cov xaim nruab nrab txuas lossis tsis tau. Li no rau qhov sib npaug 3-theem hnub qub txuas nrog load, txawm tias cov khoom siv yog 3-theem 3 xaim lossis 3-theem 4 xaim, nws tsis yog khoom siv.

Yuav ua li cas tshwm sim hauv peb-theem tsis sib npaug?

Ib qho tsis sib npaug ntawm peb theem tuaj yeem ua raupeb-theem motors thiab lwm yam peb-theem loadskom muaj kev ua haujlwm tsis zoo lossis ua tsis tiav ntxov vim yog cov hauv qab no: Kev ntxhov siab hauv lub cev muaj zog vim kom qis dua li qub torque tso zis. Siab tshaj li niaj zaus tam sim no hauv motors thiab peb-theem rectifiers.

Yuav ua li cas yog cov theem tsis sib npaug?

Yog tusreactance ntawm peb theem tsis zoo ib yam, nws yuav ua rau qhov sib txawv tam sim no ntws hauv peb theem thiab muab qhov system tsis sib npaug. Tam sim no los ntawm txhua theem los ntawm cov kabmob lossis lub cev muaj zog muab lub ntiaj teb ntab rau lub sijhawm, ua rau muaj qhov hloov pauv tam sim no.
