Thaum lub cev muaj zog nyob hauv lub xeev ua haujlwm tsis zoo (xws li hluav taws xob, tshuab thiab ib puag ncig), lub neej ntawm lub cev muaj zog yuav luv luv.Cov laj thawj rau qhov tsis ua haujlwm ntawm lub kiv cua kauj yog: theem poob, luv luv Circuit Court, coil grounding, overload, rotor xauv, voltage imbalance, thiab surge.Hauv qab no yog cov duab ntawm ntau yam coil tsis ua haujlwm los pab koj txheeb xyuas qhov ua rau tsis ua haujlwm (siv lub tshuab 4-ncej ua piv txwv).
1. Cov duab kos tshiab
2. Tsis muaj theem
Qhov tsis muaj theem yog qhov qhib Circuit Court ntawm ib theem ntawm cov khoom siv hluav taws xob, qhov laj thawj tseem ceeb yog vim li cas lub fuse ntawm ib theem tau tawg, lub contactor qhib, lossis cov kab hluav taws xob ntawm ib theem tawg.
Kev sib txuas hnub qub (Y kev sib txuas) Delta kev twb kev txuas
Daim duab saum toj no yog daim duab ntawm 4-ncej lub cev muaj zog raug hlawv tawm ntawm theem poob.Symmetrical burnout ntawm lub cev muaj zog coils yog ib theem-tsis burnout.Yog hais tias lub hnub qub kev twb kev txuas yog tsis nyob rau theem, nws yog ib qhov zoo rau ib tug 2-ncej lub cev muaj zog tsuas muaj 2 teev ntawm coils, thiab ib tug 4-ncej lub cev muaj zog rau symmetrically hlawv tawm tsuas yog 4 teev ntawm coils.Cov txheej coils yog qhov zoo;Yog hais tias lub delta kev twb kev txuas yog tawm ntawm theem, lub 2-ncej lub cev muaj zog burns 2 teev ntawm coils symmetrically, thiab 4-ncej lub cev muaj zog burns 4 teev ntawm coils symmetrically.
3. luv Circuit Court
Cov duab hauv qab no qhia tau hais tias lub cev muaj zog tsis ua haujlwm yog tshwm sim los ntawm kev sib kis, hnav, kev co, thiab lwm yam.

4. Coil grounding
Cov duab hauv qab no qhia tau hais tias lub cev muaj zog tsis ua haujlwm yog tshwm sim los ntawm kev sib kis, hnav, kev co, thiab lwm yam.

5. Tshaj dhau
Overloading lub cev muaj zog yuav ua rau lub cev muaj zog overload.
Lus Cim: Ob qho tib si under-voltage thiab over-voltage tuaj yeem ua rau rwb thaiv tsev puas thiab ua rau overload.
6. Lub rotor raug kaw
Qhov xwm txheej no yuav ua rau muaj cua sov ntau hauv lub cev muaj zog, feem ntau yuav yog vim kev pib nquag lossis nquag thim rov qab ntawm lub cev muaj zog.
7. Tsis sib npaug peb-theem voltage
Qhov hluav taws xob tsis sib xws yuav ua rau muaj kev puas tsuaj rau cov rwb thaiv tsev, uas tej zaum yuav yog vim lub zog tsis ruaj khov thiab cov xaim tsis zoo.
Nco tseg: Ib feem pua ntawm qhov tsis sib xws tuaj yeem ua rau muaj rau txog rau kaum feem pua ntawm qhov tsis txaus ntseeg tam sim no.
8. Surge
Qhov xwm txheej pom hauv daim duab hauv qab no feem ntau tshwm sim los ntawm lub zog hluav taws xob.Lub zog hluav taws xob tuaj yeem tshwm sim los ntawm cov khoom siv hluav taws xob xws li daim phiaj hluav taws xob, xob laim, capacitors, thiab lwm yam.
