Cov bushings siv rau qhov tsis tshua muaj hluav taws xob winding (s) ntawm lub tshuab hloov pauv feem ntau yog hom khoom nrog cov plooj (porcelain) lossis epoxy insulator. … Lawv lub hom phiaj yog tswj qhov hluav taws xob nyob ib puag ncig ntawm tus neeg xyuas pib kom qhov hluav taws xob faib ntau yam sib xws thoob plaws cov kab hluav taws xob nyob ib puag ncig hauv bushing.
Yuav siv cov bushing yog dab tsi?
Bushings, (qee zaus hu ua cov kabmob tiaj tus, cov bushings tiaj, lossis lub tes tsho bearings) txo kev sib txhuam ntawm ob qhov chaw zawv zawg rau ib leeg.
Qhov zoo ntawm bushing yog dab tsi?
Qhov txiaj ntsig tseem ceeb ntawm bushing, piv rau kev sib txuas ruaj khov, yog tsis muaj suab nrov thiab kev co kis tau. Lwm qhov zoo dua yog tias lawv xav tau me ntsis kom tsis muaj roj nplaum.
Yuav ua li cas transformer bushings ua?
Cov capacitor bushing yog ua los ntawm txheej ntawm cov khoom siv hluavtaws (s.r.b.p.) interleaved nrog nyias txheej ntawm cov ntawv hlau rau ntawv impregnated nrog cov khoom siv. Qhov tshwm sim yog ib tug series ntawm capacitor nrog ib tug capacitor tsim los ntawm ob txheej ntawm hlau ntawv nyiaj nrog s.r.b.h. cylinder nyob nruab nrab ntawm.
Lub hom phiaj ntawm kev cog ntoo hauv tsev yog dab tsi?
Bushings los ntawm txhais tau tias feem ntau yog ib feem cylindrical tshem tau rau qhov qhib los yog bore (raws li ib feem ntawm cov neeg kho tshuab). Lawv yog siv los txwv qhov loj ntawm qhov qhib, txhawb nqa lub nra, tiv thaiv lwm tus tswv cuab lossis ua tus qhia.

Vim li cas transformer ntsuas hauv kva?
Transformers raug ntsuas nyob rau hauv kVA vim qhov poob tshwm sim hauv cov transformers yog ywj siab ntawm lub hwj chim yam. KVA yog lub zog ntawm lub zog. Nws yog kev sib txuas ntawm lub zog tiag tiag thiab lub zog reactive. Transformers yog tsim los yam tsis xav txog kev thauj khoom txuas.
Vim li cas cov khoom siv dielectric siv hauv capacitor?
Ib qho khoom siv dielectric yog siv los cais cov paib hluav taws xob ntawm lub capacitor. Cov khoom siv insulating no tseem ceeb txiav txim siab txog cov khoom ntawm cov khoom. Lub dielectric qhov tsis tu ncua ntawm cov khoom txiav txim siab npaum li cas ntawm lub zog uas lub capacitor tuaj yeem khaws cia thaum siv hluav taws xob.
Vim li cas cov alloys siv hauv cov khoom siv hluav taws xob cua sov?
Raws li peb paub alloys muaj siab resistivity thiab siab melting point piv rau cov hlau ntshiab. Yog li cov hlau tsis tuaj yeem yooj yim hlawv lossis oxidize ntawm qhov kub siab dua. Tam sim no raws li peb xav kom kub siab dua hauv cov khoom siv cua sov yog li peb siv cov alloys hauv cov khoom siv cua sov.
Vim li cas ferromagnetic core siv hauv transformer?
Lub peev xwm ntawm hlau lossis hlau nqa cov hlau nplaum sib nqus yog ntau dua li huab cua. Qhov peev xwm nqa tau flux hu ua permeability. Yog li hlau core yog siv nyob rau hauv transformer nyob rau hauv qhov chaw cua core. … Cov transformers zoo li no tsis muaj txiaj ntsig vim qhov feem pua ntawm cov flux los ntawm thawj kauj uas txuas lub kauj thib ob yog me me.
Vim li cas cov phiaj xwm tseem ceeb siv rau hauv kev siv nyiaj txiag thiab kev kwv yees?
Lub Rooj Milestones yog ib qho tseem ceeb tshaj plaws hauv koj txoj kev npaj ua lag luam. Nws teeb txoj kev npaj rau hauv cov tswv yim, cov ntsiab lus tseem ceeb, nrog cov peev txheej tiag, hnub kawg, thiab kev tswj xyuas lub luag haujlwm. Nws pab koj ua kom pom tseeb thaum koj tab tom sau koj txoj kev npaj ua lag luam, thiab tom qab ntawd, cov lus Milestones thiab cov phiaj xwm-vs.
