Qhov nce ntawm tus nqi hluav taws xob tas li ua rau ntau tus neeg xav txog qhov xav tau los txhim kho kev ywj pheej ntawm lawv tus kheej lub zog. Tsis tas li ntawd, qee zaum qhov no yog tib txoj hauv kev los muab cov hluav taws xob zoo txaus. Kev tshawb nrhiav kev daws teeb meem ntawm kev muab tus kheej nrog qhov hluav taws xob ua rau qhov xav tau kom nkag siab tias lub tshuab hluav taws xob ua li cas.
Txawm hais tias tam sim no muaj ob peb lub tswv yim daws teeb meem uas tso cai rau koj kom tau txais hluav taws xob los ntawm yuav luag tsis muaj dab tsi, lawv tsis pom qhov siv tau, ua tsis tau zoo, muab txoj hauv kev rau lub sijhawm sim kev xaiv nrog lub tshuab hluav taws xob.
Yam yuavtsum tau kawm uantej los tsim lub tshuab tsim khoom
Kawm yuav ua li cas thiaj tsim tau lub tshuab hluav taws xob ua raws li kev nco qab txog cov hauv paus ntawm kev tshawb fawb hluav taws xob. Nyob rau hauv seem ntawm cov motors, nws tau hais meej meej tias ib qho ntawm lawv tuaj yeem ua haujlwm tsis yog raws li cov neeg siv khoom, hloov cov haujlwm ntawm cov nqi mus rau hauv lub zog ntawm lub zog ntawm cov ncej sib hloov, tab sis kuj nyob rau hauv hom kev sib hloov, hloov lub sijhawm ntawm lub tshuab mus rau hauv lub tshuab hluav taws xob. muaj peev xwm ntawm cov terminals. Cov yam ntxwv no hu ua txoj caireversibility ntawm cov tshuab hluav taws xob. Qhov tseeb, qhov no yog lub hauv paus ntawm yuav ua li cas lub tshuab hluav taws xob tsim.
Engines
Thaum xaiv lub tshuab hluav taws xob, koj yuav tsum paub tias lawv tuaj yeem ncaj qha lossis hloov tam sim no. Txij li thaum xav txog yuav ua li cas lub tshuab hluav taws xob tsim, feem ntau lawv txhais tau hais tias "hloov", ces peb yuav tsis tham txog "mus tas li". AC tshuab muaj nyob rau hauv variations nrog ib theem thiab squirrel-cage rotor. Nyob rau hauv thawj rooj plaub, qhov kawg ntawm windings yog coj mus rau ib tug tshwj xeeb ntaus ntawv nrog ib tug txheej ntawm kev sib cuag pads, uas yog powered los ntawm graphite "brushes". Siv cov kev daws teeb meem xws li lub tshuab hluav taws xob yog qhov nyuaj dua.
Txoj Cai Ua Haujlwm
Yuav kom nkag siab tias lub tshuab hluav taws xob ua haujlwm li cas, koj yuav tsum xav txog cov txheej txheem uas tshwm sim hauv lub cav thaum ua haujlwm. Xav txog tus qauv peb-theem. Thaum lub hwj chim siv rau lub terminals ntawm stator winding (taw ib feem), ib tug sib nqus teb tshwm sim nyob rau hauv nws, cov kab ntawm kev siv ntawm uas hla lub kaw rotor winding (ib tug rotating "nruas"). Vim qhov no, ib tug tam sim no yog induced nyob rau hauv lub tom kawg, uas generates nws tus kheej magnetic teb. Kev sib cuam tshuam ntawm ob lub teb no tsim ib lub zog. Nws yog qhov yooj yim.
Yog li ntawd, raws li txoj cai ntawm kev thim rov qab, nws yog qhov yuav tsum tau tig lub rotor los ntawm kev cuam tshuam sab nraud, thiab tshem tawm qhov hluav taws xob los ntawm stator windings. Nyob rau hauv cov generators muag nyob rau hauv khw muag khoom chains, lub torque yog tsim los ntawm ib tug roj av cav. Txawm hais tias qhov ua tau zoo ntawm cov kab ke no tsawg, nws ua haujlwm.
Ntaunuances
Cov neeg uas twb tau kawm yuav ua li cas lub tshuab hluav taws xob ua kom paub tias muaj ntau yam ntawm cov khoom sib txuas. Los ntawm unwinding tus ncej thiab txuas lub load rau lub terminals, nws yuav tsis muaj peev xwm mus qhib tag nrho lub peev xwm ntawm lub cuab yeej. Yog vim li cas rau qhov no nyob rau hauv lub fact tias tsis muaj tam sim no tshwm sim nyob rau hauv lub lem ntawm lub rotor winding (lub magnetization yog me me thiab ploj mus). Txhawm rau daws qhov teeb meem no, kev daws teeb meem zoo yog siv: ib qho thaiv ntawm cov capacitors txuas nrog hauv daim duab peb sab yog muab tso rau ntawm peb lub terminals ntawm peb-theem lub cev muaj zog raws li kev xav. Ntawd yog, ib lub xaim txuas mus rau txhua lub ces kaum los ntawm lub davhlau ya nyob twg ntawm stator winding, thiab peb qhov kev tawm mus rau lub nra kuj tawm ntawm no. Cov capacitors ntawm hom tsis-electrolytic, xws li MBGT, MBGO, thiab lwm yam, yuav tsum tau siv, lawv qhov voltage yuav tsum yog tsawg kawg yog 600 V. Lub peev xwm nyob ntawm qhov load (qhov muaj zog ntau dua, cov chav kawm ntawm capacitors siab dua) thiab engine yam ntxwv. Piv txwv li, rau lub tshuab hluav taws xob 2 kVA, lub roj teeb muaj peev xwm tsawg kawg yog 28 microfarads.
Nws tsis pom zoo kom siv lub tshuab hluav taws xob yam tsis muaj kev thauj khoom vim qhov tshwm sim cua sov. Koj kuj yuav tsum tau coj mus rau hauv tus account tias rau peb-theem hluav taws xob lub cev muaj zog, los ntawm qhov uas 220 V raug tshem tawm hauv lub tshuab hluav taws xob, lub zog yuav yog ib feem peb ntawm lub npe.
Ncej kev sib hloov ceev yuav tsum yog tsawg kawg synchronous. Txwv tsis pub, yuav pom qhov txo qhov zaus thiab/lossis voltage.
Feem ntau cov neeg muaj lus nug: "Yuav ua li cas thiaj ua tau lub tshuab hluav taws xob cua?" Txhua yam yog qhov tseeb: cua yog qhov chaw pub dawb uas ib txwm muaj. Cov tshuaj no suav nrog: cav; cov hniav ntawm tus ncej, tuned rau ib lub kaum ntse ntse; block ntawm capacitors. Yog thawj zaug npaj los tsimtsis tshua muaj hluav taws xob, yuav tsum muaj ib qho inverter ntxiv thiab roj teeb.
