Kev xaiv thiab ceev faj ntawm parametric tswj fais fab mov
Lub parametric tswj fais fab mov, uas yog, hom ferromagnetic resonance (los yog magnetic saturation type) tswj fais fab mov, siv cov nonlinearity ntawm cov khoom sib nqus thiab cov capacitance resonance txoj kev kom ua tiav voltage stabilization. Vim yog siv lub hauv paus ntsiab lus ntawm ferromagnetic resonance, nws muaj qee qhov kev ua tau zoo, xws li:
1. Kev ntseeg siab (tsis muaj cov khoom siv hluav taws xob, cov qauv yooj yim).
2. Muaj peev xwm tiv thaiv kev cuam tshuam (tuaj yeem paub cov tswv yim thiab tso tawm ob txoj kev los tiv thaiv kev cuam tshuam).
3. Tsis muaj qhov tso tawm overvoltage tshwm sim.
4. Dav input voltage ntau (qis txwv ntawm input voltage yuav tshaj 50 feem pua ntawm ib nrab load).
5. Lub sijhawm teb luv luv (kwv yees li 40ms).
Nyob rau tib lub sijhawm, nws kuj coj qee qhov tsis xws luag rau cov tswj fais fab:
1. Kev hloov pauv tsis zoo: Cov kev hloov pauv ntawm qhov kev thauj khoom yuav ua rau txo qis ntawm qhov kev tswj hwm qhov hluav taws xob. Cov zis raug txo qis thiab qhov kub thiab txias nce, yog li kev saib xyuas tshwj xeeb yuav tsum tau them thaum hloov mus rau qhov muaj zog inductive, muaj zog capacitive thiab cuam tshuam loads (xws li motors, tshuab cuab yeej, rectifiers, thiab lwm yam).
2. Cov yam ntxwv tsis zoo: Cov khoom siv hluav taws xob ferroresonant yog rhiab heev rau cov zaus zaus. Thaum lub mains zaus hloov los ntawm 1 feem pua, cov zis voltage hloov los ntawm 2 feem pua. Thaum qhov sib txawv ntawm qhov sib txawv loj heev, nws yuav tsis tuaj yeem ua kom ruaj khov ntawm qhov hluav taws xob lossis txawm tias tsim cov oscillations tsawg zaus. Yog li ntawd, Nws tsis tuaj yeem siv rau hauv cov dej me me thiab lub tshuab hluav taws xob hauv cov cheeb tsam roob.
3. Kub kub thiab suab nrov: Txij li ib feem ntawm cov hlau nplaum ntawm lub transformer ua haujlwm nyob rau hauv lub saturated lub xeev, qhov tsim kub ntawm lub ntsiab transformer yog siab dua li ntawm cov transformers zoo tib yam; qhov sib nqus flux leakage tshwm sim los ntawm lub xeev saturated kuj tseem loj, uas ua rau lub suab nrov ntawm lub tshuab tag nrho siab dua li ntawm cov khoom siv hluav taws xob zoo tib yam. Lub hwj huam mov loj dua.
Yog li ntawd, kuv xav ceeb toom rau txhua tus neeg koom tes lossis cov neeg siv ncaj qha kom xyuam xim rau cov hauv qab no:
1. Parameters Cov kev tswj fais fab mov yog rhiab heev rau kev hloov ntawm lub mains zaus vim yog lub hauv paus ntsiab lus. Thaum qhov zaus hloov pauv los ntawm 1 feem pua (0.5HZ), cov zis voltage hloov los ntawm 2 feem pua (4.4V). Yog li ntawd, nws yuav tsum tau siv nrog ceev faj nyob rau hauv cov cheeb tsam nrog loj zaus deviations thiab thaum generators muab hwj chim.
Thib ob, nyob rau hauv kev siv tiag tiag ntawm qhov ntsuas ntsuas hluav taws xob, peb kuj yuav tsum tau them sai sai rau qhov loj thiab qhov xwm txheej ntawm cov khoom thauj. Vim muaj qhov sib txawv ntawm qhov kev thauj khoom, muaj ntau qhov ua tsis tiav uas yuav muaj kev cuam tshuam loj rau nws. Common loads tuaj yeem muab faib ua capacitive, inductive, resistive, cuam tshuam, thiab nonlinear. Lawv cuam tshuam rau parametric tswj fais fab mov yog raws li nram no:
1. Capacitive: Capacitive load yuav ua rau kom lub peev xwm resonance ntawm lub parameter stabilized fais fab mov, nce qhov ruaj khov ntawm cov zis voltage, thiab nthuav cov kev tswj ntawm qhov voltage, tab sis tib lub sij hawm nws kuj yuav ua rau kom cov zis voltage thiab kub. sawv ntawm lub transformer. Kev kub siab dhau lawm yuav ua rau lub rwb thaiv tsev transformer puas.
2. Inductive: Inductive load yuav txo cov resonant peev ntawm lub parameter tswj fais fab mov, uas ua rau poob nyob rau hauv cov zis voltage, deteriorating lub stability ntawm cov zis voltage, thiab txo qhov ntau ntawm voltage tswj.
3. Resistivity: Qhov Performance index ntawm parametric tswj fais fab mov yog ntsuas nyob rau hauv ib tug resistive load, uas muaj me ntsis cuam tshuam.
4. Impulse: Feem ntau ntawm cov loads no yog motors, uas nws pib inrush tam sim no yog 5 mus rau 7 npaug ntawm cov kev khiav hauj lwm tam sim no, uas yuav ua rau ib tug loj poob ntawm cov zis voltage, ua rau lub load tsis txav los yog oscillate.
5. Tsis-linearity: Nws txhais tau hais tias tam sim no thiab voltage ntawm lub load tsis nyob rau hauv ib tug linear kev sib raug zoo. Nws instantaneous mem tes tam sim no loj, qhov nruab nrab lub hwj chim tsis loj, tab sis lub instantaneous hwj chim yog loj, uas yuav ua rau cov zis voltage ntawm parameter stabilized fais fab mov mus oscillate.
Rau cov loads saum toj no, 1, 2, 3, thiab 4 tuaj yeem siv txoj kev nce lub zog ntawm lub zog hluav taws xob kom txo tau qhov cuam tshuam ntawm qhov load. Rau cov khoom tsis muaj kab, nws raug nquahu kom tsis txhob siv cov khoom siv hluav taws xob tswj hwm thiab hloov lawv nrog ZTY tsis siv neeg AC stabilized fais fab mov. Piezoelectric fais fab mov, JJW precision purification tswj fais fab mov, UPS uninterruptible fais fab mov thiab lwm yam khoom siv fais fab. Rau siab zog, thov xaiv SBW fais fab nyiaj them hom voltage stabilizer thiab SJW microcomputer them hom voltage stabilizer series fais fab mov raws li qhov zoo tshaj plaws.
