Mica daim kab xev rwb thaiv tsev

Ib txheej txheej rwb thaiv tsev

Cov khoom siv hluav taws xob thiab thermal cov yam ntxwv ntawm mica ntawv yog lub hauv paus rau mica daim kab xev rwb thaiv tsev. Daim ntawv mica yog sib txuas nrog qee qhov ntau ntawm cov cua sov- cov khoom siv tiv taus thiab ntxiv dag zog nrog cov ntaub ntawv xws li iav ntaub, polyester zaj duab xis, polyester lev, lossis polyimide zaj duab xis, nyob ntawm seb cov khoom tsim. Qhov kev tsim kho hybrid no lav tias daim kab xev ua tiav cov txheej txheem rwb thaiv tsev ntawm cov khoom siv hluav taws xob thaum ua kom haum rau kev qhwv.

Rau cov ntawv thov siv lub tshuab nqus tsev siab Impregnation (VPI), cov khoom siv yog qhov tseem ceeb tshwj xeeb. Cov iav ntaub yog siv rau daim ntaub ntawv uas yuav tsum tau zoo txhua yam muaj zog thiab tsim kua muag kuj, thaum polyester zaj duab xis muaj qhov tseem ceeb ntawm qhov yooj. Cov khoom siv txhawb nqa yog xaiv raws li qhov tsim nyog cov cuab yeej cuab tam. Daim ntawv mica tuaj yeem tsim los ntawm calcined muscovite lossis phlogopite.

Tsawg-Resin VPI Performance

Tsawg dua 15% resin binder muaj nyob rau hauv mica daim kab xev rwb thaiv tsev ua rau VPI; Lub cev muaj peev xwm ntawm binder yog 10-12 g / m². Thaum lub tshuab nqus tsev- txheej txheem siab, lub hom phiaj yog txhawm rau ua kom cov impregnating resin nkag mus rau hauv daim kab xev. Iav- ntaub- txhawb nqa VPI cov qauv feem ntau muaj qhov tuab ntawm 0.10–0.18 hli, tag nrho qhov hnyav ntawm 118–164 g / m², lub zog dielectric ntawm 15–25 kV / mm, thiab lub zog tensile tsawg kawg yog 150 N / cm. Qhov ntau ntawm huab cua permeability yog 1600-2500 s / 100 ml.

Kev xaiv los ntawm Kev Siv Hluav Taws Xob

VPI daim kab xev ntsuas rau Class F (155 degree) thiab Class H (180 degree) daim ntawv thov raug teev nyob rau hauv qhov chaw. Cov khoom lag luam muaj plaub cov qauv ib txwm muaj, txhua qhov sib luag rau qee yam haujlwm. Polyester zaj duab xis-rov qab daim kab xev yog qhov kev xaiv ib txwm siv rau kev dav dav - lub hom phiaj motors mus txog 11 kV, txawm hais tias polyester xav tau nyiam rau tes- cov kab mob vim nws cov softer kov ua rau phau ntawv layup yooj yim dua. High-voltage coils thiab traction motors, uas muaj cov txheej txheem nruj dua rau lub zog tensile thiab kub tsis kam, yuav tsum muaj fiberglass- cov khoom siv ntxiv.
