Nws tshwm sim li no: muaj lub tshuab me me zoo, drilling lossis tig, siv los ntawm 380 volts. Nws tuaj yeem ntsia tau rau hauv chav ua haujlwm hauv tsev lossis hauv lub tebchaws. Tab sis qhov teeb meem yog, nyob rau hauv cov chav no tsuas muaj cov sockets zoo tib yam.
Nyob rau hauv rooj plaub uas nws tsim nyog los txuas peb-theem hluav taws xob lub cev muaj zog, thiab tsuas yog ib-theem hluav taws xob qhov hluav taws xob muaj, koj tuaj yeem tawm ntawm qhov xwm txheej los ntawm lub zog ib qho ntawm cov windings los ntawm cov theem hloov pauv. - pib capacitor. Yog li koj tuaj yeem tau txais kev hloov pauv rau theem peb ntawm qhov hluav taws xob hloov ntawm 120 degrees.
Nyob rau hauv cov ntaub ntawv zoo tagnrho, lub peev xwm loj yuav tsum tau ua kom lub cev muaj zog, thiab thaum ncav cuag qhov ntsuas qhov nrawm, lwm qhov, me dua. Txhawm rau ua tiav qhov no, ib lub tswv yim yog siv uas ua rau nws muaj peev xwm tua tau ntau tshaj ob qho tib si manually thiab txiav, tawm tsuas yog nws cov nqi ua haujlwm.
Nyob rau hauv cov xwm txheej uas cov windings txuas nrog lub hnub qub, lub peev xwm ua haujlwm ntawm kev ua haujlwm capacitor yog txiav txim los ntawm tus qauv:
Av=2800 (I/U)
Thaum qhov kev sib txuas ntawm daim duab peb sab, qhov kev vam khom sib txawv:
Av=4800 (I/U)
Txawm li cas los xij, kev sib txuas lub cev muaj zog hauv daim duab peb sab yog qhov tsis xav tau, vim tias qhov no AC voltage yuav tsum yog 380 volts ntawm txhua tus, thiab tsuas yog 220 volts hauv tsev network.
Rau qhov yooj yim ntawm kev xam tus nqi ntawm lub peev xwm ntawm lub capacitor, koj tuaj yeem siv tus qauv, raws li qhov
Ср=Р/10, Sp=R/5, qhov twg
P - hwj chim, Watt;
Сп - capacitance ntawm pib capacitor, mF;
Сп - capacitance ntawm lub pib capacitor, mF.
Yog li, lub peev xwm ntawm lub tshuab pib pib yuav tsum yog ib nrab mus rau ob thiab ib nrab zaus ntawm kev ua haujlwm.
Standard AC voltage yog 220 volts. Cov lus nug tshwm sim ntawm yuav ua li cas txiav txim siab qhov loj ntawm qhov tam sim no uas tshwm sim hauv cov qauv saum toj no.
Nws yooj yim. Lub zog ntsuas ntawm lub cav yog paub, nws tau qhia rau ntawm lub phaj txuas rau nws lub cev thiab ua haujlwm raws li hom ntawv hla tebchaws rau nws.
I=P / (1, 73 U cos φ), qhov twg
I – tus nqi tam sim no, Amp;
U - voltage (220 Volts);
φ – theem kaum.
Los ntawm kev suav kom raug thiab xaiv lub pib capacitor rau lub tshuab hluav taws xob, koj tuaj yeem txuas yuav luag txhua yam ntawm peb-theem hluav taws xob motors rau ib-theem network. Qee tus ntawm lawv yuav ua haujlwm zoo dua, uas yog, lawv cov yam ntxwv yuav nyob ze rau cov ntawv hla tebchaws thaum lawv ib txwm qhib (piv txwv li AOL, UAD, APN series). Series MA, tus cwj pwm nyob rau hauv hais tias lawv tsim siv ib tug ob lub tawb tswv yim ntawm ib tug squirrel-cage rotor,yuav qhia tau qhov phem tshaj plaws.
Thaum xaiv lub capacitor pib, ib tus yuav tsum tau coj mus rau hauv tus account qhov tseeb tias thaum lub sijhawm pib yuav muaj cov txiaj ntsig tam sim no uas ntau zaus ntau dua li tus nqi nominal. Yog li, nws yuav tsum nco ntsoov tias qhov hla ntawm tus neeg xyuas pib uas muab lub zog rau lub cev muaj zog yuav tsum tau xaiv nrog cov npoo.
Tam sim no hais txog qhov twg pib lub capacitor tuaj yeem siv los txuas peb-theem lub cev muaj zog rau ib-theem-theem network. Electrolytic capacitances tuaj yeem siv tau, tab sis lub xub ntiag ntawm rectifier diodes hauv Circuit Court yuav ua rau nws nyuaj thiab txo qhov kev cia siab ntawm tag nrho cov kab ke. Txawm tias Henry Ford tau sib cav hais tias qhov tsawg dua, qhov tsawg dua qhov yuav muaj kev tawg.
Nws yooj yim dua thiab txhim khu kev qha rau nruab ib daim ntawv capacitor pib. Qhov voltage qhia ntawm nws rooj plaub yuav tsum tshaj 220 volts.
