Fais fab system resonance overvoltage? Wuhan UHV tshwj xeeb hauv kev tsim khoomseries resonance, nrog ntau yam khoom xaiv thiab kev kuaj hluav taws xob. Nrhiavseries resonance, xaiv Wuhan UHV.
Hauv qhov system fais fab, qee qhov inductance thiab capacitance Cheebtsam tuaj yeem tsim ntau yam oscillation circuits thaum lub kaw lus ua haujlwm lossis ua haujlwm tsis zoo. Hauv qee qhov chaw muaj zog,series resonancephenomenon yuav tshwm sim, ua rau overvoltage loj nyob rau hauv ib co Cheebtsam ntawm lub system. Qhov tshwm sim no yog hu ua fais fab system resonance overvoltage. Overvoltage tshwm sim muaj ntau heev nyob rau hauv daim phiaj fais fab, uas tuaj yeem ua rau muaj kev puas tsuaj rau cov chaw siv hluav taws xob thiab hluav taws xob hauv cheeb tsam txhua lub sijhawm, ua rau muaj kev puas tsuaj loj heev. Resonant overvoltage tshwm sim feem ntau thaum lub sijhawm ua haujlwm ib txwm muaj, thiab nws qhov kev puas tsuaj kuj tseem ceeb.Muaj ntau ntau hom resonant overvoltage:
(1) Linear resonance overvoltage
Lub resonant Circuit Court yog tsim los ntawm inductive yam tsis muaj hlau cores (xws li inductance ntawm kis kab thiab to inductance ntawm transformers) los yog inductive ntsiab nrog hlau cores uas muaj excitation yam ntxwv ze rau linearity (xws li arc suppression coils) thiab capacitive ntsiab nyob rau hauv lub system.
(2) Ferromagnetic resonance overvoltage
Lub resonant Circuit Court yog tsim los ntawm inductive Cheebtsam nrog hlau cores (xws li tsis muaj -load transformers thiab voltage transformers) thiab capacitive Cheebtsam ntawm lub system. Vim lub saturation tshwm sim ntawm hlau core inductance Cheebtsam, cov inductance tsis nyob rau hauv Circuit Court yog nonlinear. Hom kab hluav taws xob no uas muaj cov khoom siv hluav taws xob tsis muaj hluav taws xob yuav ua rau ferromagnetic resonance thaum qee qhov kev cuam tshuam resonance tau ntsib.
(3) Parameter resonance overvoltage
Lub Circuit Court yog tsim los ntawm inductive Cheebtsam nrog lub sij hawm hloov nyob rau hauv inductance tsis (xws li lub synchronous reactance ntawm ib tug salient ncej generator uas txawv raws sij hawm ntawm Kd thiab Kq) thiab system capacitive Cheebtsam (xws li tsis muaj - cov kab). Thaum qhov tsis sib xws, lub zog txuas mus ntxiv mus rau lub zog resonant los ntawm kev hloov pauv hauv inductance, ua rau tsis muaj zog resonance overvoltage.
