1, sib tawg tau hluav taws xob voltage
Xyoo tsis ntev los no, vim muaj teeb meem loj txog kev xav tau, xav kom tsis txhob muaj teeb meem loj txog hluav taws rau ntawm kab, zoo voltage qib sib yog cuab kev: tawg tau tsav nyob 3kV underground kev xaiv tsa; petrochemical kev lag luam thiab tawg tau tsav nyob thee mine loj zoo ventilated xaiv lOkV running maj mam tawm, hwj chim yuav tau me me thiab muab tsawg mintsis thiab, ib txhia kuj txais 110 ~ 160kW koom xwm ntau lawm, lOkV kom. Ua lokV manufacturing nqi rau tej lub me zog nce, ua hlau no kuj nyuaj.
Thaum luv voltage tawg tau lub cev muaj zog zaus thaum 60Hz, qhov zoo tshaj plaws rau 460V nyob voltage, kev manufacturers uas tawg tau tsav yuav yooj yim rau 50Hz derived khoom.
tawg tau kev tiv thaiv hluav taws xob 2, kawm
Kev pab tiv thaiv hoob kawm los ntawm kev ntxiv leb tom qab tus IP. 1th xaus ntawm sab laug yog ib yam puavpheej plua plav, yog tus ntiv 2nd waterproof. Tus buyer tej zaum rau purchase nqi, los yog hoob kawm kev tiv thaiv tsis kuj to taub, los sis qib IP54 qhov chaw xaiv kom tawg tau tsav ntawm IP44, ntawm txawm tawg tau Motors IP23. Kev piv txwv luag zeb tawg tau tsav siv nyob rau hauv chaw nres tsheb fais fab tuag, koj yuav tsum xaiv cov IP54.
tawg tau hluav taws xob rwb thaiv tsev hoob kawm 3,
Pav ntawm theem rwb thaiv tsev, yuav tsum koom tes nrog tawg tau kub lub cev muaj zog ntxiv. Hauv siv yog muaj ob tug zauv uas muab lus thiab demand ob tog yuav tsum tau muaj kev pom zoo:
Kub-sawv ① txwv txoj kev zus tau tej cov muaj thiab muaj voltage tawg tau tsav, tshaj 90% cov chav kawm ntawv f insulated. Thiaj li ua kom txoj hauj lwm uas tawg tau tsav, chaw tsim tshuaj paus 90% ntawd hais rau tus qauv xaiv f hoob rwb thaiv tsev, kub siab ntxiv kawm b txhob khij ″. Hoob b rwb thaiv tsev tso cai rau qhov kub tshaj plaws yog 130 ° c, f-hoob kawm yog 155. Xav txog 40 ℃ chaw sov thiab raug dab thiab cov ntaub ntawv txog cov fluctuations nyob rau hauv tag nrho 5 c 10 c, kub sawv hoob b rwb thaiv tsev tawg tau lub cev muaj zog Hoobkas-teev tsuas pub muaj 80K. Thaum uas cov f hoob rwb thaiv tsev siv thiab ua cov tawg tau tsav, Hoobkas txwv thaum twg koj nias b, txwv kub siab ntxiv yuav tsum muaj 90K (underground tawg tau tsav yog 95K).
② hoob kawm h rwb thaiv tsev kawm h rwb thaiv tsev tso cai rau qhov kub thiab txias mus 180 c. xovxwm h qib tsim thiab siv thiab ua tawg tau tsav, bearings, thiab cov roj nyob hauv lub teb chaws no tsis tau. Hoob h rwb thaiv tsev ntawm windings, rau lub Hoobkas no tsis nyuaj, lub ntsiab yog tus kub bearings. Yog li ntawd, tsis yog tus kawg resort (xws li 60 ℃ ambient kub los ntim tau xwb mas kuj tawg tau tsav), tsis txhob siv cov chav kawm ntawv h rwb thaiv tsev tawg tau motors.
