Cov voltage nruab nrab ob kab (piv txwv li 'L1' thiab 'L2') yog hu ua kab rau kab (los yog theem mus rau theem) hluav taws xob . Cov hluav taws xob hla txhua qhov cua (piv txwv nruab nrab 'L1' thiab 'N' yog hu ua kab rau nruab nrab (los yog theem hluav taws xob ).
Yog li ntawd, yuav ua li cas koj hloov kab mus rau kab voltage mus rau nruab nrab?
Piv txwv li ib qho kev sib npaug zoo kawg nkaus, txhua theem yog sib cais los ntawm 120 degrees thiab cov kab-rau-nruab nrab voltage ntawm txhua theem yog tib yam. Tsuav yog ob qhov kev xav no muaj tseeb, ces qhov loj ntawm qhov kab rau kab voltage yog 1.732 * Vp, qhov twg Vp yog tus kab-rau-nruab nrab voltage.
Tom qab, lo lus nug yog, kab kab hluav taws xob yog dab tsi? Kab-rau-Line Voltage . Kab-rau-kab voltage yog qhov txawv ntawm ob tug ncej voltages (e.g., vab=van−vbn) Los ntawm: Hluav Taws Xob Hluav Taws Xob, 2017.
Tom qab ntawd, lo lus nug yog, qhov txawv ntawm kab thiab theem voltage yog dab tsi?
Kab hluav taws xob yog cov hluav taws xob ntsuas nruab nrab ib ob kab in a peb- theem Circuit Court. Phase voltage yog cov hluav taws xob ntsuas hla ib feem hauv a peb- theem qhov chaw los yog load. Kab tam sim no yog tam sim no los ntawm ib qho twg kab nruab nrab ib tri- theem qhov chaw thiab load.
Yuav ua li cas koj nrhiav tau kab rau kab voltage?
Cov kab rau kab voltage yog cov hluav taws xob los yog muaj peev xwm ntawm ob lub xov hlau. Rau ob hluav taws xob qhov tseem ceeb uas sib koom ib qho hlau, koj tuaj yeem sib piv lawv li vac = vab -vcb ua los yog, ntxiv ob voltages as vac = vab + vbc ua. Cov ntawv sau rau qhov sib txawv no hauv hluav taws xob tuaj yeem cia koj xam theem rau lub ntiaj teb hluav taws xob.
