Kev rwb thaiv tsev ntawm lub cev muaj zog siab

Lub rwb thaiv tsev ntawm lub kaujlub cev muaj zog siabmuaj kev cuam tshuam loj heev rau lub neej ua haujlwm thiab kev lag luam ntawm lub cev muaj zog, uas yog ib qho teeb meem uas txhua tus tsim qauv thiab kws kho tshuab yuav tsum xav txog kom zoo. Lub kauj hluav taws xob siab tuaj yeem hu ua lub plawv ntawm lub cev muaj zog rau qee qhov, uas txiav txim siab ncaj qha rau lub neej ua haujlwm ntawm lub cev muaj zog, thiab kev ua tau zoo ntawm cov khoom siv rwb thaiv tsev, uas yog ib qho tseem ceeb ntawm lub kauj, yog qhov tseem ceeb.
Cov qauv rwb thaiv tsev thiab cov txheej txheem kho ntawm cov motors high-voltage hauv ntau lub tebchaws tuaj yeem piav qhia luv luv raws li hauv qab no:
(1) Daim kab xev mica uas muaj ntau daim nplaum yog qhwv tas li, ziab hauv lub tshuab nqus tsev, thiab tom qab ntawd nias kub (molded lossis hydraulic).
(2) Daim kab xev mica uas muaj ntau daim nplaum yog qhwv tas li, tsis tas yuav ziab hauv lub tshuab nqus tsev, thiab ncaj qha tsim los ntawm kev txhaj tshuaj kub.
(3) Cov kab xev mica uas tsis nplaum ntau dua yog qhwv tas li, nqus tsev rau hauv cov tshuaj tsis muaj kuab tshuaj, thiab tom qab ntawd nias kub.
(4) Daim kab xev mica (lossis daim kab xev dawb embryo) raug qhwv tas li, uas yog, kab yog tawg, thiab tom qab ntawd cov tshuaj tsis muaj kuab tshuaj yog impregnated tag nrho.
Tsis tas li ntawd xwb, muaj cov roj hmab silicone rwb thaiv tsev, nrog rau cov roj hmab silicone thiab mica daim kab xev sib xyaw rwb thaiv tsev. Cov roj hmab silicone tiv taus cua sov, tiv taus txias, tiv taus dej noo thiab tiv taus xeb zoo heev, tab sis kev ua haujlwm hluav taws xob thiab lub zog tsim kua muag tsis zoo, thiab nws tsuas yog siv rau cov cav hluav taws xob siab ua haujlwm hauv cov chaw tshwj xeeb hauv qab 6 kV.

Cov kev cai yooj yim rau high voltagekev rwb thaiv tsev kauj:
 Muaj zog txaus
Ntawm ib sab tes, nws yog qhov xav tau tias cov rwb thaiv tsev ntawm cov cav yuav tsum nyias li sai tau, tab sis ntawm qhov tod tes, nws yuav tsum muaj qee qhov ntug hauv cov nqe lus ntawm lub zog hluav taws xob. Vim tias lub cev muaj zog ua haujlwm, yuav raug rau huab cua overvoltage thiab kev ua haujlwm overvoltage cuam tshuam: luv luv Circuit Court tam sim ntawd, kub thiab voltage ntawm lub luag haujlwm ntev, cov rwb thaiv tsev yuav maj mam laus, kev co thiab kev ntxhov siab mechanical kuj tseem yuav ua rau cov rwb thaiv tsev puas tsuaj, ntxiv rau, hauv cov txheej txheem tsim khoom kom ua tiav ntau qhov kev sim voltage, txhua lub sijhawm, yuav tsim qee qhov kev puas tsuaj me me ntawm cov qauv rwb thaiv tsev, uas yog, qhov hu ua cumulative effect. Tag nrho cov no yuav ua rau lub zog hluav taws xob rwb thaiv tsev poob qis. Yog li ntawd, thaum tsim cov qauv coil, yuav tsum muaj qee yam kev nyab xeeb.
 Kev poob qis dielectric
Thaum lub tsev rwb thaiv tsev raug hluav taws xob hloov pauv, qhov poob dielectric tshwm sim. Qhov nruab nrab ntawm qhov kub tsis loj, tab sis qhov tsis muaj zog ntawm cov cua sov feem ntau yog concentrated. Yog tias qhov tsis muaj zog ntawm qhov kub tshwm sim los ntawm qhov poob dielectric ntau dua li qhov kub tawm, qhov kub hauv zos ntawm lub rwb thaiv tsev yuav txuas ntxiv mus, qhov kub nce ntxiv thiab ua rau qhov poob dielectric nce ntxiv, qhov kev ua tau zoo ntawm lub rwb thaiv tsev yuav poob qis heev. Yog li ntawd, qhov poob dielectric hauv lub cev muaj zog siab yuav tsum tsis txhob tshaj qhov teev tseg.
 Zoo tiv thaiv corona
Thaum cov cav hluav taws xob siab ua haujlwm, qhov xwm txheej corona yuav tshwm sim ob qho tib si sab hauv thiab ntawm qhov chaw ntawm cov rwb thaiv tsev, ua kom nrawm dua qhov laus thiab xeb ntawm cov rwb thaiv tsev. Yog li ntawd, rau cov generators ntawm 6.3kV thiab siab dua thiab cov cav ntawm 6kV thiab siab dua, lawv cov kauj yuav tsum siv cov kev ntsuas tiv thaiv corona. Lub kauj ntawm 6kV lub cev muaj zog tsis tuaj yeem kho mob tiv thaiv corona feem ntau, tab sis nws yuav tsum kho mob tiv thaiv corona rau cov cav uas siv rau hauv ib puag ncig tsis zoo lossis muaj peev xwm loj.

 Kev ua haujlwm zoo thermal laus
Qhov kev tiv thaiv cua sov ntawm cov qauv rwb thaiv tsev yuav tsum ua tau raws li qib tiv thaiv cua sov uas cov khoom xav tau. Nyob rau hauv qhov kev ua haujlwm ntev ntawm qhov kub ua haujlwm, lub neej ua haujlwm ib txwm ntawm cov rwb thaiv tsev tuaj yeem lav tau.
Feem ntau, kev rwb thaiv tsev ntawm lub cev muaj zog muab faib ua tsib qib uas tiv taus cua sov: A, E, B, F, H. Thaum lub sijhawm ua haujlwm, qhov kub ntawm qhov chaw kub tshaj plaws hauv lub rwb thaiv tsev ntawm lub cev muaj zog yuav tsum tsis pub tshaj qhov kub siab tshaj plaws uas tau teev tseg hauv chav kawm rwb thaiv tsev. Feem ntau, yuav tsum tso qhov sib txawv ntawm 5 ~ 10 ℃. Yog tias cov qauv rwb thaiv tsev yog ua los ntawm cov ntaub ntawv rwb thaiv tsev ntawm ntau qib tiv taus cua sov sib txawv, nws qib tiv taus cua sov tuaj yeem ua qauv thiab soj ntsuam tag nrho los ntawm nws cov qauv.
 Ua tau lub luag haujlwm ntawm kev ntxhov siab ntawm lub cev
Lub rwb thaiv tsev ntawm lub kauj yuav tsum muaj peev xwm tiv taus qee qhov kev ntxhov siab yam tsis muaj kev tawg lossis ua rau muaj kev puas tsuaj. Lub kauj ua haujlwm vim yog qhov coefficient nthuav dav ntawm cov hlau thiab rwb thaiv tsev tsis zoo ib yam, kev hloov pauv kub, rwb thaiv tsev yuav raug kev ntxhov siab, lub cev muaj zog ntev dua, qhov cuam tshuam ntau dua; Vim yog lub zog hluav taws xob, qhov kawg ntawm lub kauj kuj tseem yuav tsim kev co, tshwj xeeb tshaj yog thaum lub cev muaj zog cuam tshuam los ntawm luv luv Circuit Court, pib thiab nres tam sim no, lub zog hluav taws xob feem ntau ua rau lub kauj deform; Yog li ntawd, lub rwb thaiv tsev yuav tsum muaj qee qhov elasticity thiab lub zog kho tshuab.
