Lub coil insulation ntawmhigh voltage lub cev muaj zogmuaj kev cuam tshuam zoo rau lub neej kev pabcuam thiab kev lag luam ntawm lub cev muaj zog, uas yog ib qho teeb meem uas txhua tus tsim qauv thiab cov kws tshaj lij yuav tsum ua tib zoo xav txog. Lub high-voltage kauj tuaj yeem hu ua lub plawv ntawm lub cev muaj zog rau qee qhov, uas ncaj qha txiav txim siab lub neej kev pabcuam ntawm lub cev muaj zog, thiab kev ua haujlwm ntawm cov khoom siv insulating, uas yog ib qho tseem ceeb ntawm cov kauj, yog qhov tseem ceeb.
Cov txheej txheem rwb thaiv tsev thiab cov txheej txheem kev kho mob ntawm high-voltage motors nyob rau hauv ntau lub teb chaws tuaj yeem raug sau tseg raws li hauv qab no:
(1) Multi-adhesive mica daim kab xev yog txuas ntxiv qhwv, lub tshuab nqus tsev qhuav, thiab tom qab ntawd kub nias (pwm lossis hydraulic).
(2) Multi-adhesive mica daim kab xev yog txuas ntxiv qhwv, tsis muaj lub tshuab nqus tsev ziab, thiab ncaj qha tsim los ntawm kub molding.
(3) Tsawg nplaum mica daim kab xev yog txuas ntxiv qhwv, nqus rau hauv cov kuab tshuaj tsis muaj zog, thiab tom qab ntawd kub xovxwm tsim.
(4) Daim kab xev mica (lossis dawb embryo daim kab xev) yog txuas ntxiv qhwv, uas yog, cov kab yog tawg, thiab tom qab ntawd cov kuab tshuaj tsis muaj tshuaj yog impregnated tag nrho.
Tsis tas li ntawd, muaj silicone roj hmab rwb thaiv tsev, nrog rau silicone roj hmab thiab mica daim kab xev sib xyaw rwb thaiv tsev. Lub tshav kub tsis kam, txias tsis kam, noo noo tsis kam thiab corrosion kuj ntawm silicone roj hmab yog zoo heev, tab sis cov hluav taws xob kev ua tau zoo thiab tsim kua muag lub zog tsis zoo, thiab nws tsuas yog siv rau high-voltage motors khiav hauj lwm nyob rau hauv tshwj xeeb ib puag ncig hauv qab no 6 kV.
Basic yuav tsum tau rau high voltagecoil rwb thaiv tsev:
Muaj zog hluav taws xob txaus
Ntawm qhov tod tes, nws yog qhov xav tau tias cov rwb thaiv tsev ntawm cov motors yog nyias raws li qhov ua tau, tab sis ntawm qhov tod tes, nws yuav tsum muaj qee qhov npoo ntawm lub zog hluav taws xob. Vim tias lub cev muaj zog hauv kev ua haujlwm, yuav raug cuam tshuam rau atmospheric overvoltage thiab kev ua haujlwm overvoltage cuam tshuam: tam sim luv luv Circuit Court, kub thiab voltage ntawm lub luag hauj lwm mus sij hawm ntev, lub rwb thaiv tsev yuav maj mam aging, vibration thiab mechanical kev nyuaj siab yuav ua rau lub rwb thaiv tsev, ntxiv rau, nyob rau hauv lub manufacturing txheej txheem mus nqa tawm ib tug xov tooj ntawm withstand voltage xeem, txhua txhua lub sij hawm, yuav ua tau ib tug tej yam subtleties ntawm kev puas tsuaj ntawm cov qauv, yog li ntawd, insulating cov ntaub ntawv. cumulative nyhuv. Tag nrho cov no yuav ua rau cov rwb thaiv tsev hluav taws xob poob qis. Yog li ntawd, thaum tsim cov qauv coil, yuav tsum muaj qee yam kev nyab xeeb.
Tsawg dielectric poob
Dielectric poob tshwm sim thaum cov qauv insulating raug rau qhov chaw hluav taws xob hloov pauv. Dielectric poob ntawm qhov nruab nrab kub, txawm hais tias tsis loj, tab sis nyob rau hauv ib tug neeg tsis muaj zog cov ntsiab lus ntawm lub tshav kub yog tshwj xeeb tshaj yog concentrated, yog hais tias lub qaug zog cov ntsiab lus ntawm lub tshav kub tshwm sim los ntawm lub dielectric poob ntau tshaj li lub tshav kub emission, lub zos kub ntawm lub rwb thaiv tsev yuav nce mus ntxiv, qhov kub thiab txias thiab txhawb ntxiv nce nyob rau hauv lub dielectric poob, lub rwb thaiv tsev ntawm lub electromechanical kev ua tau zoo yuav yog ib tug ntse poob ntawm lub zog ntawm cov ntsiab lus. Yog li ntawd, nyob rau hauv high-voltage motor dielectric poob yuav tsum tsis txhob tshaj tus nqi teev.
Zoo corona tiv thaiv
Thaum lub tshuab hluav taws xob muaj zog ua haujlwm, corona phenomenon tuaj yeem tshwm sim ob sab hauv thiab ntawm qhov chaw ntawm cov rwb thaiv tsev, ua kom cov laus thiab corrosion ntawm cov rwb thaiv tsev. Yog li ntawd, rau cov tshuab hluav taws xob ntawm 6.3kV thiab siab dua thiab lub cev muaj zog ntawm 6kV thiab siab dua, lawv cov coils yuav tsum tau ntsuas los tiv thaiv kab mob. Lub kauj ntawm 6kV lub cev muaj zog tsis tuaj yeem tiv thaiv kev kho mob feem ntau, tab sis nws yuav tsum yog kev kho mob tiv thaiv kab mob rau lub cev muaj zog uas siv rau hauv ib puag ncig tsis zoo lossis muaj peev xwm loj.
Kev ua haujlwm zoo thermal aging
Lub tshav kub tsis kam ntawm cov txheej txheem thermal rwb thaiv tsev yuav tsum ua kom tau raws li cov qib cua sov uas xav tau los ntawm cov khoom. Nyob rau hauv lub sij hawm ntev ntawm kev ua hauj lwm kub, lub neej kev pab cuam ntawm lub rwb thaiv tsev yuav guaranteed.
Lub cev muaj zog rwb thaiv tsev feem ntau muab faib ua A, E, B, F, H tsib qib cua sov. Thaum lub sijhawm ua haujlwm, qhov kub ntawm qhov kub tshaj plaws nyob rau hauv lub cev muaj zog winding rwb thaiv tsev yuav tsum tsis txhob siab tshaj qhov kub siab tshaj plaws teev nyob rau hauv chav kawm rwb thaiv tsev. Feem ntau, nws yog ib qho tsim nyog yuav tsum tawm ntawm 5 ~ 10 ℃. Yog hais tias cov txheej txheem rwb thaiv tsev yog tsim los ntawm cov ntaub ntawv rwb thaiv tsev ntawm cov qib sib txawv ntawm cov cua sov, nws cov qib cua sov tuaj yeem raug simulated thiab kev ntsuam xyuas los ntawm nws cov qauv qauv.
tuaj yeem tiv taus lub luag haujlwm ntawm txhua yam kev ntxhov siab
Lub rwb thaiv tsev ntawm lub kauj yuav tsum muaj peev xwm tiv taus qee yam ntawm cov neeg kho tshuab kev ntxhov siab yam tsis muaj kev tawg lossis ua rau muaj teeb meem deformation. Coil hauv kev ua haujlwm vim qhov nthuav dav coefficient ntawm hlau thiab rwb thaiv tsev tsis zoo ib yam, qhov kub thiab txias hloov, rwb thaiv tsev yuav raug nro, lub cev muaj zog ntev dua, qhov cuam tshuam ntau dua; Vim yog lub zog hluav taws xob, qhov kawg ntawm lub kauj yuav ua rau muaj kev vibration, 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 electromagnetic feem ntau ua rau lub kauj deform; Yog li ntawd, cov rwb thaiv tsev yuav tsum muaj qee yam elasticity thiab txhua yam muaj zog.
