Tam sim no, asynchronous units siv feem ntau hauv hom lub cev muaj zog. Cov khoom siv hluav taws xob uas muaj zog ntau dua 0.5 kW feem ntau ua rau peb-theem, qis zog - ib-theem. Thaum lub sijhawm lawv muaj sia nyob ntev, cov tsav tsheb asynchronous tau pom cov ntawv thov dav hauv ntau yam lag luam thiab kev ua liaj ua teb. Lawv siv rau hauv lub tshuab hluav taws xob ntawm tshuab hoisting-thiab-thauj cov tshuab, hlau txiav tshuab, conveyors, kiv cua thiab twj. Lub cev muaj zog tsis tshua muaj zog siv nyob rau hauv kev siv tshuab ua haujlwm.

Cov Lus Qhia

Kauj ruam 1

Siv peb-theem induction lub cev muaj zog. Tshem tawm cov davhlau ya nyob twg. Txhawm rau ua qhov no, tshem tawm ob tus ntsia hlau nrog rab hau ntswj uas ruaj ruaj rau rooj plaub. Qhov xaus ntawm lub cev muaj zog windings feem ntau yog coj tawm mus rau 3 lossis 6 lub davhlau ya nyob twg thaiv. Hauv thawj kis, qhov no txhais tau hais tias qhov theem stator windings txuas nrog "delta" lossis "lub hnub qub". Hauv ob, lawv tsis txuas nrog lwm tus. Hauv qhov no, lawv txoj kev txuas tseeb los ua ntej. Kev suav nrog los ntawm "lub hnub qub" muab rau kev sib koom ua ke ntawm qhov ntsuas cua ntawm tib lub npe (xaus lossis pib) mus rau qhov xoom. Thaum sib txuas nrog "daim duab peb sab", txuas qhov kawg ntawm thawj lub winding nrog pib ntawm ob, tom qab ntawd xaus rau qhov kawg thib ob - nrog rau thaum pib ntawm peb, thiab tom qab ntawd xaus rau qhov thib peb - nrog rau thaum pib ntawm thawj Cov.

Kauj ruam 2

Nqa ib qho ohmmeter. Siv nws thaum qhov ua rau ntawm induction lub cev muaj zog windings tsis muaj cim. Txiav txim siab peb windings nrog cov ntaus ntawv, tsim lawv conventionally I, II thiab III. Txuas txhua ob qho ntawm lawv hauv cov kab los nrhiav qhov pib thiab xaus ntawm txhua qhov cua. Thov siv ib qho kev hloov pauv ntawm 6 txog 36 V. Rau ob hnub ntawm peb qhov kev ntsuas thib ib, txuas ib qho hluav taws xob tam sim no. Cov tsos ntawm kev hloov hluav taws xob qhia tau hais tias windings I thiab II tau txuas nrog, yog tias tsis yog, tom qab ntawd rov qab. Hauv qhov no, sib pauv cov davhlau ya nyob twg ntawm ib qho ntawm windings. Tom qab ntawv cim pib thiab xaus ntawm I thiab II windings. Txhawm rau txiav txim siab qhov pib thiab xaus ntawm qhov thib peb winding, hloov qhov kawg ntawm cov kab windings, piv txwv li II, III, thiab rov ua ntsuas ntsuas raws li hom txheej txheem saum toj no.

Kauj ruam 3

Txuas cov ntsuas hluav taws xob ib ntu-hloov mus rau peb-theem asynchronous lub cev muaj zog, uas tau suav nrog hauv ib-ntu network. Nws lub peev xwm xav tau (hauv μF) tuaj yeem txiav txim siab los ntawm tus qauv C = k * Iph / U, qhov twg U yog qhov voltage ntawm ib-theem network, V, k yog coefficient uas yog nyob ntawm kev sib txuas ntawm windings, Iph yog qhov rated theem tam sim no ntawm lub tshuab hluav taws xob, A. Nco ntsoov tias thaum cua ntawm lub asynchronous hluav taws xob lub cev muaj kev sib txuas los ntawm "daim duab peb sab", tom qab ntawd k = 4800, "lub hnub qub" - k = 2800. Siv daim ntawv capacitors MBGCH, K42-19, uas yuav tsum raug ntsuas rau qhov voltage tsis tsawg tshaj li qhov voltage ntawm cov khoom xaib. Nco ntsoov tias txawm tias muaj qhov suav tseeb tias muaj lub zog muaj peev xwm, lub tshuab hluav taws xob tsis muaj zog yuav tsim kho lub zog tsis tshaj 50-60% ntawm nominal.
