Qhov sib txawv ntawm cov khoom siv ntau zaus thiab lub tshuab fais fab zaus
Qhov txawv ntawm cov khoom siv ntau zaus thiab fais fab zaus tshuab
Cov cuab yeej siv high-frequency siv high-frequency switching technology los hloov UPS ntawm lub hwj chim zaus transformers nyob rau hauv rectifiers thiab inverters nrog high-frequency switching ntsiab, feem ntau hu ua high-frequency machines. Cov tshuab ua haujlwm siab yog qhov me me thiab ua haujlwm siab. Lub tshuab fais fab zaus: UPS uas siv fais fab zaus transformer li rectifier thiab inverter Cheebtsam feem ntau hu ua fais fab zaus tshuab. , Lub tshuab high-frequency tsis muaj ib qho kev sib cais transformer, thiab nws cov zis xoom kab muaj cov high-frequency tam sim no, feem ntau yog los ntawm kev sib cuam tshuam ntawm lub mains grid, lub pulsating tam sim no ntawm UPS rectifier thiab high-frequency inverter, thiab harmonic cuam tshuam ntawm lub load, thiab lwm yam. Qhov cuam tshuam voltage tsis tsuas yog cov nqi siab thiab nyuaj rau kev tshem tawm. Txawm li cas los xij, qhov tso zis xoom-hauv av voltage ntawm lub tshuab fais fab zaus qis dua, thiab tsis muaj cov khoom siv ntau zaus, uas yog qhov tseem ceeb dua rau kev sib txuas lus kev ruaj ntseg ntawm lub computer network. Cov zis ntawm lub tshuab high-frequency tsis cais los ntawm lub transformer. Yog tias lub tshuab hluav taws xob inverter yog luv luv, qhov siab DC voltage ntawm lub tsheb npav DC (DC BUS) ncaj qha mus rau lub load, uas yog ib qho kev nyab xeeb, tab sis lub tshuab fais fab zaus tsis muaj qhov teeb meem no. Lub tshuab fais fab zaus muaj zog tiv thaiv kev cuam tshuam muaj peev xwm.
Cov cuab yeej siv hluav taws xob ntau yog hais txog lub tshuab X-ray nrog lub tshuab hluav taws xob siab ua haujlwm ntau dua 20kHz, thiab lub tshuab fais fab zaus hais txog lub tshuab X-ray nrog lub tshuab hluav taws xob siab ua haujlwm zaus tsawg dua 400Hz. Lub tshuab fais fab zaus muaj 100Hz sine ripple tom qab 50Hz fais fab zaus fais fab mov tau tsa thiab kho. Tom qab lim, tseem muaj ntau tshaj 10% ntawm cov ripple. Lub tshuab ua haujlwm siab muaj qhov ua haujlwm siab, thiab qhov hluav taws xob tom qab kev hloov kho hluav taws xob siab yog qhov tseem ceeb DC, qhov ripple tuaj yeem tsawg dua 0.1%. Qhov sib txawv high-voltage voltages sib haum mus rau cov kab hluav taws xob ntawm cov hluav taws xob sib txawv, yog li tsim X-rays ntawm qhov sib txawv wavelengths. Qhov ntau dua qhov X-ray spectrum yog, qhov tawg qis dua, thiab qhov pom tseeb dua. Cov zis kab spectrum ntawm lub hwj chim zaus tshuab yog complex, tus nqi ntawm X-rays ntawm tus yam ntxwv zaus nyob rau tib lub sij hawm yog me me, cov stray tawg kab yog ntau, thiab cov duab yog qhov muag plooj. Lub tshuab ua haujlwm siab muaj qhov yooj yim tawm spectrum, tsis tshua muaj kab sib txawv, pom meej meej, thiab txo cov kab tawm tag nrho ntau dua 50% piv nrog lub tshuab fais fab zaus.
