Dab tsi yog hom AC voltage stabilized fais fab mov?
Hais txog cov qauv thiab hom kev tswj fais fab, feem ntau lawv tuaj yeem muab faib ua plaub pawg. DC, AC, inverter thiab hloov cov khoom siv fais fab. Rau cov plaub pawg ntawm ntau hom kev tswj fais fab. Txawm hais tias lawv txoj kev ua haujlwm thiab cov ntsiab lus zoo ib yam, tab sis tib yam kuj muaj ntau qhov sib txawv. Peb ntu nram qab no rau plaub yam sib txawv thiab hom kev tswj fais fab rau kev qhia ntxaws.
Thawj qeb yog AC tswj fais fab mov, AC muab faib ua ib-theem thiab peb-theem tswj fais fab mov, kuj tuaj yeem muab faib ua kev sib cuag thiab tsis sib cuag tswj fais fab. Hauv kev siv tswv yim, nws tuaj yeem raug sau tseg raws li cov kev faib tawm hauv qab no ntawm cov khoom siv hluav taws xob AC uas nquag siv:
① ferromagnetic resonant AC voltage regulator. Tsim los ntawm saturated choke thiab cov khoom siv capacitor, nrog cov yam ntxwv tsis tu ncua volt-ampere.
② magnetic amplifier hom AC voltage regulator. Sib nqus amplifier thiab autotransformer nyob rau hauv series, kev siv hluav taws xob circuits los hloov lub impedance ntawm magnetic amplifier kom stabilize cov zis voltage.
③Sliding hom AC voltage regulator. Stabilize cov zis voltage los ntawm kev hloov txoj hauj lwm ntawm zawv zawg sib cuag ntawm lub transformer.
Induction AC voltage regulator. Los ntawm kev hloov cov theem sib txawv ntawm theem nrab thiab thawj qhov hluav taws xob ntawm lub transformer, cov zis AC voltage yog stabilized.
⑤ Thyristor AC voltage regulator. Lub thyristor yog siv los ua lub zog hloov pauv. High stability, ceev teb thiab tsis muaj suab nrov. Txawm li cas los xij, nws ua rau muaj kev cuam tshuam rau cov khoom siv sib txuas lus thiab cov khoom siv hluav taws xob.Tom qab xyoo 1980, muaj peb hom tshiab ntawm AC voltage regulators: compensated AC voltage regulator. Tus lej tswj hom thiab stepping hom AC voltage regulator. Purification hom AC voltage regulator. Nws muaj kev sib cais zoo, tuaj yeem tshem tawm qhov cuam tshuam loj heev ntawm daim phiaj hluav taws xob.
Qhov thib ob loj qeb yog DC voltage regulator:
Kuj tseem hu ua DC voltage regulator. Feem ntau ntawm nws cov khoom siv hluav taws xob yog AC voltage, thaum AC muab hluav taws xob hluav taws xob lossis cov khoom siv hluav taws xob hloov pauv, qhov tso tawm ncaj qha hluav taws xob ntawm tus tswj hwm tuaj yeem nyob ruaj khov. Cov yam ntxwv ntawm tus regulator yog voltage stability, ripple yam thiab teb ceev.
Qhov thib peb qeb yog inverter voltage regulator fais fab mov
Lub npe hu ua inverter tswj fais fab mov tseem hu ua inverter fais fab mov, lub inverter fais fab mov siv 16- ntsis Motorola processor tswj, high-frequency PWM tsim, tus thawj imported Mitsubishi 1GBT tsav. Kev ua tau zoo ntawm ntau dua 85%. Teb ceev ceev, rau 100% de-loading / loading, lub sij hawm teb ntawm voltage stabilization yog nyob rau hauv 2ms. Lub zog hloov hluav taws xob ntau dhau lub peev xwm, tam sim no tuaj yeem tiv taus 300% ntawm cov ntsuas tam sim no. Ntshiab waveform, siab thiab ruaj khov zaus, tsis cuam tshuam magnetic yoj (EMI, EMC). Kev hloov hluav taws xob ntau zaus tsis yog tsuas yog lub zog zoo tshaj plaws rau R & D thiab kev sim, chav ntsuas, tab sis kuj yog tus qauv siv hluav taws xob rau EM / EMC / kev kuaj kev nyab xeeb.
Qhov thib plaub yog hloov pauv tswj fais fab mov
Daim duab schematic thiab sib npaug sib npaug ntawm cov khoom siv hluav taws xob hloov hluav taws xob, uas yog tsim los ntawm tag nrho-yoj rectifier, switching tube V, excitation signal, tam sim no-continuing diode Vp, lub zog-storage inductor, thiab filtering capacitor C. Qhov tseeb, Lub hauv paus tseem ceeb ntawm kev hloov hluav taws xob tswj hluav taws xob yog DC transformer.
Muaj lwm hom CNC tswj fais fab mov:
CNC tswj fais fab mov: nws yog los ntawm qhov chaw soj ntsuam nyob rau hauv qhov tso zis ntawm cov khoom siv sampling, tam sim no voltage nrog cov rated voltage los ua ib qho kev sib piv, xyuas, xws li cov kev sib piv yog tsis zoo, ces xa cov ntaub ntawv mus rau lub hauv paus chaw ua hauj lwm (CPU. ), lub hauv paus processor los ua qhov voltage ntxiv rau cov lus txib. Nyob rau tib lub sijhawm, qhov chaw kuaj xyuas seb puas muaj cov khoom siv hluav taws xob tau qhib thiab tawm. Tom qab lees paub tias tsis muaj qhov yuam kev, lub hauv paus processor ua rau cov lus txib ntawm voltage ntxiv los tswj cov khoom siv hluav taws xob ua haujlwm kom ncav cuag tus qauv ntawm cov ntsuas hluav taws xob. Yog hais tias tus nqi yog qhov zoo, lub hauv paus processor yuav ua rau cov lus txib ntawm voltage txo, thiab tag nrho cov txheej txheem yuav digitized nyob rau hauv tsuas yog 0.048 vib nas this.
