Cov duab thiab qhov loj ntawm cov qhov rotor muaj qhov cuam tshuam ncaj qha rau qhov tsis kam ntawm rotor thiab cov dej xau, uas yuav cuam tshuam rau lub cev muaj zog ua haujlwm, lub zog fais fab, lub zog siab tshaj plaws, lub zog pib thiab lwm yam ntsuas kev ua tau zoo. Kev ua tau zoo uas cuam tshuam yog qhov tseem ceeb heev raulub cev muaj zogcov khoom.
Thaum ua haujlwm tiag tiag, feem ntau yuav tsum tso tseg qhov kev xav tau lwm yam khoom rau qee yam kev ua tau zoo. Cov lus hais qub "koj tsis tuaj yeem muaj koj lub ncuav mog qab zib thiab noj nws ib yam nkaus" yog qhov tsim nyog ntawm no. Tau kawg, qee qhov kev hloov pauv thev naus laus zis hauv cov ntaub ntawv tshiab thiab cov txheej txheem tshiab yuav ua txhaum txoj cai no ib ntus. Piv txwv li, thaum ntxov ntawm kev siv lub tshuab rwb thaiv tsev siab nrog "mica daim kab xev nrog tsawg dua kua nplaum hmoov" ua cov khoom tseem ceeb ua ke nrog cov txheej txheem tshiab ntawm "lub tshuab nqus tsev siab immersion txheej", nws ib zaug ua tiav qhov cuam tshuam ntawm "muaj koj lub ncuav mog qab zib thiab noj nws ib yam nkaus" hauv kev txo cov tuab rwb thaiv tsev thiab txhim kho voltage thiab corona tsis kam. Txawm li cas los xij, nws tseem tsis tuaj yeem tshem tawm cov kev txwv ntawm cov cai thiab ib txwm yuav tsum ntsib qhov nyuaj-rau-tuav kev tsis sib haum xeeb lossis kev txaj muag.
1 Kev sib npaug ntawm kev ua tau zoo ntawm kev pib ua tau zoo thiab lub peev xwm overload
Yuav kom txhim kho lub peev xwm ntawm lub cev muaj zog, qhov siab tshaj plaws torque yuav tsum tau nce, yog li qhov rotor leakage reactance yuav tsum tau txo qis; thiab txhawm rau kom tau raws li qhov pib me me tam sim no thiab qhov pib loj torque thaum lub sijhawm pib, qhov cuam tshuam ntawm daim tawv nqaij rotor yuav tsum tau nce ntau li ntau tau, tab sis qhov rotor qhov leakage magnetic flux thiab leakage reactance yuav tsum tau nce ntxiv.
2 Kev sib npaug ntawm kev ua haujlwm tau zoo thiab kev ua tau zoo pib
Peb paub tias kev ua kom lub rotor tsis kam nce ntxiv tuaj yeem txhim kho kev ua haujlwm pib ntawm lub cev muaj zog, xws li txo qhov rotor qhov thiab siv ob lub tawb rotor, tab sis vim yog qhov nce ntawm rotor tsis kam thiab qhov to tam sim no, qhov poob tooj liab ntawm stator thiab rotor yuav nce ntxiv ntau, ua rau kev ua haujlwm txo qis.
3 Kev kuaj xyuas thiab sib npaug ntawm lub zog fais fab thiab kev ua haujlwm pib
Txhawm rau txhim kho qhov kev ua tau zoo ntawm lub cev muaj zog, peb siv cov nyhuv ntawm daim tawv nqaij, xws li siv cov qhov tob nqaim, cov qhov convex, cov qhov riam zoo li rab riam, cov qhov tob lossis ob lub qhov tawb squirrel kom nce qhov tsis kam ntawm rotor thaum pib, tab sis qhov cuam tshuam ncaj qha tshaj plaws yog kom nce Qhov rotor qhov xau txo qis, qhov rotor leakage inductance nce ntxiv, thiab qhov tam sim no reactive ntawm rotor nce ntxiv, uas feem ntau yuav ua rau muaj kev txo qis ntawm lub zog fais fab.
4 Kev sib npaug ntawm kev ua haujlwm thiab lub zog ntawm lub zog
Yog tias thaj chaw ntawm lub rotor qhov nce thiab qhov tsis kam txo qis, qhov poob tooj liab ntawm lub rotor yuav txo qis thiab qhov ua tau zoo yuav nce ntxiv; txawm li cas los xij, vim yog qhov txo qis hauv thaj chaw permeability magnetic ntawm lub rotor yoke, qhov tsis kam magnetic yuav nce thiab qhov ceev ntawm magnetic flux yuav nce, ua rau qhov poob hlau nce thiab qhov fais fab kom nce. poob qis. Ntau lub cev muaj zog nrog kev ua haujlwm zoo li lub hom phiaj zoo tshaj plaws yuav ib txwm muaj qhov xwm txheej no: kev txhim kho kev ua haujlwm zoo yog qhov tseem ceeb, tab sis qhov tam sim no ntsuas loj thiab qhov fais fab tsawg. Cov neeg siv khoom yws tias cov cev muaj zog ua haujlwm siab tsis zoo li cov cev muaj zog ib txwm.
Muaj ntau yam teeb meem ntawm kev nce thiab kev poob hauv kev tsim lub cev muaj zog. Tsab xov xwm no tsuas yog hais txog cov yam ntxwv sab nraud xwb. Txhawm rau kom sib npaug cov kev sib raug zoo ntawm kev ua tau zoo no, peb yuav tsum tshawb nrhiav cov yam ntxwv sab hauv kom tob thiab siv cov kev xav rov ua dua ntawm kev nce thiab kev poob los daws qhov kev tsis sib haum xeeb lossis kev txaj muag.
