Kodi pali ubale wotani pakati pa kulumikizana kwa katatu ndi nyenyezi komanso ubwino ndi kuipa kwake?

Momwemonsomota ya magawo atatuikhoza kulumikizidwa ndi kulumikizana kwa makona atatu, kogwirizana ndi mphamvu yamagetsi yochepa; Ikhozanso kulumikizidwa malinga ndi njira yolumikizira nyenyezi, yogwirizana ndi mphamvu yamagetsi yapamwamba; Mphamvu yamagetsi yapamwamba ndi yowirikiza katatu kuposa muzu wa mphamvu yamagetsi yochepa. Mwachitsanzo, mota ya 380V yokhala ndi mphamvu yamagetsi atatu, ngati yolumikizidwa ndi mphamvu yamagetsi, mphamvu yamagetsi yofanana ndi 660V. Kulumikizana kwina kuyenera kufanana ndi mphamvu yamagetsi.

Mota yolumikizidwa ndi nyenyezi siimatulutsa kayendedwe ka magazi mkati, zomwe mwachionekere ndizabwino kuposa kulumikizana kwa triangular.
Chifukwa chakuti kuzunguliza kwa magawo atatu sikungakhale koyenera, nthawi zonse pamakhala kusiyana pang'ono muInjini ya magawo atatuVoltage, yomwe imapanga kayendedwe ka madzi mkati mwa katatu, zomwe zimapangitsa kuti kutentha kwa injini kuchepe komanso kuti mphamvu yake ichepe. Kulumikizana kwa katatuku kumapangidwanso pazifukwa zakale, ndiko kuti, komwe kumatchedwa Star-Triangle Start, Star-Triangle Start kumatha kuchepetsa bwino mphamvu yoyambira, koma kumachepetsa torque yoyambira, kotero ingagwiritsidwe ntchito pokhapokha ngati pali katundu wochepa kapena palibe katundu woyambira.

Tikuwona kuti mota ya fan pump imatha kuyatsidwa ndi nyenyezi-triangle, koma palibe chiyambi cha nyenyezi-triangle pa crane, kukweza kumayambitsidwa kwambiri ndi kukana kwa rotor series, chifukwa chiyani kumabweretsa mavuto ambiri, pali chifukwa. Zachidziwikire, momwe zinthu zilili pano poyambira kusintha ma frequency zathetseratu mavuto otere.

Kaya makina a mawaya atatu kapena anayi (opanda nthaka), ngodya yamagetsi pakati pa ma voltage a magawo atatu ndi kusiyana kwa magawo 120 pansi pa mikhalidwe yabwino. Akuganiza kuti chifukwa cha kusokoneza nthawi ndi nthawi, ma harmonics a 3N amapangidwa mu gawo lozungulira la load terminal, 3N*120=360N, zomwe zikusonyeza kuti gawo la ma voltage a ma harmonics a magawo atatu ndi lofanana, ngati amplitude ndi yofanana, ma harmonics a 3N a magulu atatu a ma voltage a mzere adzathetsedwa kwathunthu, ndiko kuti, palibe ma harmonics ambiri a 3 mu voltage pakati pa mizere.

Pa kulumikizana kwa katatu, mafunde a 3N harmonic omwe ali pamwambapa omwe ali mu gawo lomwelo amafupikitsidwa mu katatu iyi ndipo amasungidwa mu katatu iyi kuti apange kuzungulira kosatha. Chifukwa chake, kuti pakhale ma harmonics, kulumikizana kwa katatu kapena nyenyezi kumatha kusankhidwa malinga ndi ngati ma harmonics a 3N ndi otheka mu voltage kapena current.
