Hauv kev lag luam fais fab, 220 volts thiab 380 volts raug suav hais tias yog qhov tsis tshua muaj hluav taws xob, feem ntau yog siv hluav taws xob hauv tsev. 35,000 volts thiab saum toj no yog high voltage, feem ntau yog siv rau kev xa hluav taws xob. Nyob nruab nrab, nws yog nruab nrab voltage. Thiab nws yog qhov txaus ntshai heev los kov cov kab hluav taws xob siab lossis ua haujlwm nyob hauv cov kab.
Thickness ntawm tooj liab daim kab xev
Lub nominal thickness ntawm tooj liab daim kab xev rau shielding ib leeg-core cable yuav tsum tsis txhob tsawg tshaj li 0.12 hli. Copper wire shielding txheej yog tsim los ntawm cov xoob xoob xoob xoob xoob xoob xoob xoob xoob uas nws cov npoo yog nruj nreem khi nrog thim rov qab cov kab mob tooj liab los yog tooj liab tapes.
Qhov nruab nrab ntawm qhov sib txawv ntawm cov xov tooj hlau uas nyob ib sab yog tsis ntau tshaj 4 hli. Txoj kev tiv thaiv ntawm tooj liab hlau thiab tooj liab daim kab xev winding tuaj yeem txhim kho qhov tsis zoo ntawm txoj hlua tooj liab winding shielding txoj kev.
Tsis muaj ib qho oxide txheej uas tsim los ntawm kev sib tshooj tooj liab, tsis muaj zog dabtsi yog khoov thiab kub thiab txias deformation, thiab tooj liab strip winding tsis yooj yim rau arched thiab embedded nyob rau hauv insulating shielding txheej.
Hla ntu ntawm Hlau Shield
Qhov hla ntawm cov ntaub thaiv hlau hlau ncaj qha cuam tshuam rau lub peev xwm ntawm cov kab hluav taws xob tiv thaiv luv luv tam sim no thaum muaj kev txhaum..
Yog hais tias tus ntoo khaub lig seem me dhau, luv Circuit Court tam sim no tuaj yeem overheat lossis hlawv cov rwb thaiv tsev. Yog li ntawd, Nws yog ib qho tsim nyog los txiav txim siab txog ntu ntu ntawm cov ntaub thaiv hlau hlau raws li qhov muaj peev xwm tam sim no. Nyob rau hauv cables ntawm 10kV thiab hauv qab no, thaum tus neeg xyuas pib hla ntu tshaj 500, sim siv tooj liab hlau thaiv. Yog hais tias koj hais rau shielding nrog tooj liab daim kab xev, koj yuav tsum tau thicken lub thickness ntawm daim kab xev tooj liab.
Nyob ntawm qhov xwm txheej ntawm kev teeb tsa cable, yog hais tias nws yuav tsum nqa ib tug loj luv-circuit niaj hnub, Nws raug pom zoo kom siv tooj liab hlau thaiv kev tiv thaiv. Yog li ntawd, qhov txawv ntawm tooj liab daim kab xev shielding thiab tooj liab hlau shielding yog muaj peev xwm nqa luv-circuit tam sim no. Cov hlau tooj liab yog me ntsis loj dua (kuj nyob ntawm cov nyhuv ntawm cov hlau tooj liab). Daim kab xev tooj liab muaj qhov sib nqus sib nqus thiab thaiv cov nyhuv.
Vam tias tsab xov xwm no yuav pab tau. Txhua nqe lus nug txog cov khoom siv cable, thov tiv tauj peb.
