Yog tias koj txuas ob lub xaim ntawm peb-theem hluav taws xob, koj yuav tsis tau txais ib qho txiaj ntsig dab tsi ntxiv dua li ntawm hum. Nyob rau qhov zoo tshaj plaws, lub tshuab muaj zog yuav sib tw me ntsis. Txhawm rau kom nws pib tig, koj yuav tsum suav nrog lub zog hluav taws xob hauv ib-theem network los ntawm kev hloov chaw ntawm cov capacitors. Ntxiv mus, nws yog qhov yuav tsum tau siv ob lub capacitors (lossis lawv cov block) - pib ib ntus, uas ua haujlwm rau tsuas yog pib, thiab ua haujlwm ruaj khov.

Cov Lus Qhia
Kauj ruam 1
Xam xyuas qhov muaj peev xwm xav tau ntawm tus ua haujlwm capacitor. Nws tus nqi yog nyob ntawm hom kev sib txuas ntawm lub cev winding. Rau qhov "hnub qub" kev sib txuas, lub capacitance yog Cp = 2800 * I / U, rau kev sib txuas "peb tog" - Cp = 4800 * I / U, qhov twg Cp yog lub zog ntawm tus capacitor hauv inF, Kuv yog qhov kev noj nyob rau tam sim no A, U yog qhov tseem ceeb voltage hauv V.

Txheeb xyuas qhov tam sim no los ntawm cov qauv Hauv = P / (1.73 * Un * η * COSφ), qhov twg P yog lub zog ntawm lub cev muaj zog hauv W, η yog qhov ua tau zoo (0.8-0.9), cosφ yog lub zog ntsuas sib npaug rau 0.85, U - qhov hluav taws xob loj, 1.73 - coefficient ua cim qhov sib piv ntawm theem thiab kab tam sim no. Lub peev xwm ntawm tus pib capacitor Cn yuav tsum yog 2-3 zaug (nyob ntawm tus neeg kho tshuab tsis kam thaum lub cav pib) kom dhau lub peev xwm Cp.
Kauj ruam 3
Yog tias koj tsis xav koom nrog kev suav, koj tuaj yeem coj kwv yees kwv yees qhov muaj nqis raws li hauv qab no: ntawm P = 0.4 kW Cp = 40 μF, Cn = 80 μF; nrog P = 0.8 kW Cp = 80 μF, Cn = 160 μF; nrog P = 1.1 kW Cp = 100 μF, Cp = 200 μF; ntawm P = 1.5 kW Cp = 150 μF, Cp = 250 μF; ntawm P = 2.2 kW Cp = 230 μF, Cp = 300 μF.
Kauj ruam 4
Yuav cov pib ua haujlwm ntawm lub zog uas xav tau. Lawv cov ntsuas hluav taws xob yuav tsum muaj tsawg kawg 1.5 zaug ntawm qhov hluav taws xob loj. Txog 220 V, nws yuav tsum yog tsawg kawg 500 V. Ua ib rooj plaub (thawv) rau lub peev xwm yas lossis ntoo - kom lawv haum snugly rau hauv nws. Lub rooj sib hais yog qhov xav tau kom cov capacitors yog qhov sib cais uas tuaj yeem nyob hauv qhov chaw yooj yim ntawm qhov chaw deb ntawm lub cav kom lawv tsis txhob raug kev co thiab kev ntxhov siab hauv tshuab thaum lub sijhawm ua haujlwm.
Kauj ruam 5
Nyob rau hauv qhov kev tshwm sim uas koj yuav tsum sau qhov tsim nyog xav tau los ntawm ntau lub capacitors, txuas rau hauv parallel, i.e. muab sib dhos rau hauv tib lub thaiv uas siv ob lub xov hlau hla dhau ntawm tus capacitors thiab soldered rau lawv cov terminals.
Kauj Ruam 6
Txuas lub capacitors rau lub cev muaj zog raws li cov duab kos qhia hauv daim duab (ntawm sab xis rau lub cev muaj zog uas muaj cov cua txuas nrog los ntawm "delta", nyob sab laug - los ntawm "lub hnub qub"). Cn thiab Cp txhais tau hais tias qhov pib thiab ua haujlwm ntawm lub zog pib, ntsig txog, P yog kev hloov pauv uas suav nrog tus pib hloov hluav taws xob hauv Circuit Court, P yog kev hloov pauv uas hloov cov kev taw qhia kev sib hloov ntawm lub cav. Thaum pib lub cav, lub tog raj txuas P yuav tsum muab tua, tom qab teeb tsa kev hloov kho nws yuav tsum muab tua.
