Overload yog ib qho teeb meem tshwm simcov khoom siv cav. Tej zaum nws yuav yog vim lub cev muaj zog tsis ua haujlwm lossis lub cev muaj zog tsis txaus. Nws kuj tseem yuav yog teeb meem overload uas tus neeg siv ua thaum lub sijhawm ua haujlwm ntawm lub cev muaj zog.
Thaum muaj teeb meem overload tshwm sim hauv lub cev muaj zog, cov windings yuav muaj ntau qib ntawm kev puas tsuaj ntawm rwb thaiv tsev. Seb qhov winding tag nrho puas tsuaj lossis puas yog qhov tsis ua haujlwm hauv zos nyob ntawm qib zoo ntawm lub cev winding.
Thaum qib zoo ntawm lub cav winding yog sib xws heev, thaum lub cev muaj zog overloaded, qib ntawm kev puas tsuaj ntawm rwb thaiv tsev ntawm lub winding yuav luag zoo ib yam. Lub sijhawm no, los ntawm qhov kev xav ntawm qhov tshwm sim txhaum, tag nrho qib rwb thaiv tsev ntawm lub winding ua rau phem dua. Hauv cov xwm txheej hnyav, txheej rwb thaiv tsev ntawm lub winding tawg tag. Teeb meem tsaus ntuj. Thaum qhov zoo sib xws ntawm lub cev muaj zog winding tsis zoo, uas yog, muaj cov txuas tsis muaj zog hauv cov windings, thaum lub cev muaj zog overloaded, txawm tias me ntsis overload tuaj yeem ua rau tawg ntawm cov txuas tsis muaj zog hauv rwb thaiv tsev, uas yog, cov windings muaj qhov chaw hauv zos theem-rau-theem, av, lossis Interturn rwb thaiv tsev tsis ua haujlwm, hluav taws xob tsis ua haujlwm ntawm rwb thaiv tsev nres lub cev muaj zog los ntawm kev txuas ntxiv ua haujlwm, thiab qhov xwm txheej overload tsis cuam tshuam rau txhua lub windings.
Los ntawm kev tshuaj xyuas cov txheej txheem tswj hwm ntawm cov txheej txheem tsim khoom ntawm lub cev muaj zog, cov thev naus laus zis hluav taws xob zoo yuav muab kev tiv thaiv tshwj xeeb rau cov txuas tseem ceeb kom ntseeg tau tias tsis muaj kev phom sij zoo thaum lub sijhawm winding, inlay, wiring thiab insulation. Thaum ua haujlwm hluav taws xob Yog tias cov txheej txheem tsis tsim nyog, qhov tsis ua tiav tsis tsim nyog yuav tshwm sim thaum lub sijhawm ua haujlwm winding.
Tshwj xeeb tshaj yog rau cov cav uas pib ncaj qha, yuav tsum tau ua tib zoo saib xyuas kev tiv thaiv ntawm thawj lub kauj. Xav txog qhov cuam tshuam rau cov windings thaum lub sijhawm pib lub cav, yuav tsum tau ceev faj thaum lub sijhawm txuas hluav taws xob kom ntseeg tau tias cov kauj uas muaj kev phom sij zais cia nyob hauv lub xeev tsis nruj. Qhov no muaj txiaj ntsig zoo rau kev ntseeg siab ntawm tag nrho lub cav.
Los ntawm kev tshuaj xyuas cov xwm txheej tiag tiag ntawm cov cav tov uas muaj overloaded, txhua yam uas ua rau cov khoom siv tsis zoo ntawm lub cav yuav ua rau lub cav ua haujlwm tsis zoo. Piv txwv li, kev puas tsuaj ntawm cov khoom, kev sib tsoo ntawm lub cev muaj zog, thiab kev overloaded hnyav yog txhua yam ua rau lub cav overload.
