Qhov sib txawv ntawm hluav taws xob ib theem, hluav taws xob ob theem, thiab hluav taws xob peb theem

Hluav taws xob ib theem thiab hluav taws xob ob theem yog ob txoj kev muab hluav taws xob sib txawv, thiab muaj qhov sib txawv pom tseeb ntawm lawv hauv daim ntawv thiab voltage ntawm kev xa hluav taws xob.

Hluav taws xob ib theem yog hais txog hom kev xa hluav taws xob uas muaj ib txoj kab theem thiab ib txoj kab nruab nrab. Txoj kab theem, tseem hu ua xov hlau nyob, muab hluav taws xob rau lub nra, thaum txoj kab nruab nrab ua haujlwm ua txoj hauv kev rau tam sim no rov qab los. Lub zog ntawm hluav taws xob ib theem yog 220 volts, uas yog lub zog ntawm txoj kab theem thiab txoj kab nruab nrab.

Hauv tsev thiab chaw ua haujlwm, hluav taws xob ib theem yog hom hluav taws xob uas siv ntau tshaj plaws. Ntawm qhov tod tes, hluav taws xob ob theem yog lub voj voog hluav taws xob uas muaj ob txoj kab theem, hu ua hluav taws xob ob theem. Hauv hluav taws xob ob theem, qhov hluav taws xob ntawm cov kab theem hu ua hluav taws xob kab, uas feem ntau yog 380 volts.

Qhov sib piv, qhov hluav taws xob ntawm hluav taws xob ib theem yog qhov hluav taws xob ntawm kab theem thiab kab nruab nrab, uas hu ua qhov hluav taws xob theem. Hauv kev lag luam thiab qee yam khoom siv hauv tsev, xws li tshuab vuam, hluav taws xob ob theem siv dav.

Hauv kev xaus, qhov sib txawv tseem ceeb ntawm hluav taws xob ib theem thiab hluav taws xob ob theem yog daim ntawv thiab qhov hluav taws xob ntawm kev xa hluav taws xob. Hluav taws xob ib theem muaj ib txoj kab theem thiab ib txoj kab nruab nrab, uas haum rau hauv tsev thiab chaw ua haujlwm, thiab qhov hluav taws xob yog 220 volts. Lub zog fais fab ob theem muaj ob txoj kab theem, uas haum rau kev lag luam thiab qee yam khoom siv hauv tsev, nrog qhov hluav taws xob ntawm 380 volts.

Lub hwj chim ib theem: feem ntau yog hais txog txhua txoj kab theem (feem ntau hu ua hlau nyob) + txoj kab nruab nrab hauv 380V peb theem plaub-xaim AC fais fab mov, qhov hluav taws xob yog 220V, txoj kab theem yuav ci thaum ntsuas nrog lub cwj mem hluav taws xob qis qis, thiab txoj kab nruab nrab yuav tsis ci. Nws yog qhov chaw siv hluav taws xob feem ntau hauv lub neej txhua hnub. Ib theem yog txhua txoj kab theem hauv peb theem mus rau txoj kab nruab nrab. Nws feem ntau hu ua "hlau nyob" thiab "hlau nruab nrab". Feem ntau hais txog 220V, 50Hz AC. Lub zog ib theem kuj hu ua "hlau theem" ​​hauv kev tsim hluav taws xob.
Lub zog fais fab peb theem: Lub zog fais fab uas muaj peb lub zog AC nrog tib lub zaus, sib npaug zos, thiab qhov sib txawv ntawm 120 degrees hu ua lub zog fais fab peb theem. Nws yog tsim los ntawm lub tshuab hluav taws xob AC peb theem. Lub zog AC ib theem siv hauv lub neej txhua hnub yog muab los ntawm ib theem ntawm lub zog AC peb theem. Lub zog AC ib theem uas tsim los ntawm lub tshuab hluav taws xob ib theem tsis tshua muaj neeg siv.

Qhov txawv ntawm lub zog fais fab ib theem thiab lub zog fais fab peb theem yog tias lub zog uas lub tshuab hluav taws xob tsim tawm yog peb theem, thiab txhua theem ntawm lub zog fais fab peb theem thiab nws qhov chaw nruab nrab tuaj yeem tsim ib lub voj voog ib theem los muab lub zog rau cov neeg siv. Hauv lwm lo lus, hluav taws xob peb theem muaj peb theem xov hlau (cov xov hlau nyob) thiab ib txoj xov hlau nruab nrab (lossis cov xov hlau nruab nrab), thiab qee zaum tsuas yog siv peb theem xov hlau xwb. Raws li tus qauv Suav teb, qhov hluav taws xob ntawm cov xov hlau theem yog 380 volts AC, thiab qhov hluav taws xob ntawm cov xov hlau theem thiab cov xov hlau nruab nrab yog 220 volts AC. Hluav taws xob ib theem tsuas muaj ib txoj xov hlau nyob thiab ib txoj xov hlau nruab nrab, thiab qhov hluav taws xob ntawm lawv yog 220 volts AC. Peb theem hloov pauv tam sim no yog kev sib xyaw ntawm peb pawg ntawm cov hluav taws xob ib theem hloov pauv nrog qhov sib npaug, zaus sib npaug, thiab qhov sib txawv theem 120 °. Hluav taws xob ib theem yog kev sib xyaw ntawm txhua txoj xov hlau theem thiab cov xov hlau nruab nrab hauv hluav taws xob peb theem.

Qhov zoo ntawm kev sib piv ob qho no yog dab tsi? AC peb theem muaj ntau qhov zoo dua li AC ib theem. Nws muaj qhov zoo pom tseeb hauv kev tsim hluav taws xob, kev xa mus thiab kev faib tawm, thiab kev hloov pauv lub zog hluav taws xob mus rau hauv lub zog kho tshuab. Piv txwv li, kev tsim cov tshuab hluav taws xob peb theem thiab cov transformers txuag cov khoom siv piv rau kev tsim cov tshuab hluav taws xob ib theem thiab cov transformers ntawm tib lub peev xwm, thiab cov qauv yooj yim thiab kev ua tau zoo heev. Piv txwv li, lub peev xwm ntawm lub cev muaj zog peb theem ua los ntawm tib cov khoom siv yog 50% loj dua li ntawm lub cev muaj zog ib theem. Nyob rau hauv qhov xwm txheej ntawm kev xa tib lub zog, kab xa hluav taws xob peb theem tuaj yeem txuag tau 25% ntawm cov hlau tsis yog ferrous piv rau kab xa hluav taws xob ib theem, thiab lub zog poob tsawg dua li ntawm kab xa hluav taws xob ib theem.
