Nkag siab txog Transformer Bushings: Lawv Ua Li Cas
Lwm zaus koj taug kev dhau los ntawm cov loj grey transformers ntawm cov ncej hluav taws xob hauv koj lub zej zog, saib ze rau saum. Koj yuav pom cov ribbed, lub khob hliav qab- zoo li tej yam uas zoo li lub kaus mom loj loj uas tau muab tso rau saum. Tej zaum lawv yuav zoo li tsuas yog lwm qhov khib - saib ib feem, tab sis lawv yeej yog ib qho tseem ceeb tshaj plaws ntawm kev nyab xeeb hauv tag nrho lub zog.
Hluav taws xob ib txwm sim nrhiav txoj hauv kev nrawm tshaj plaws rau hauv av, thiab yog tias cov hlau nyob ib puag ncig tau kov cov hlau casing yam tsis muaj kev tiv thaiv zoo, txhua yam yuav ua yuam kev sai heev - xav tias sparks, tawg, ua haujlwm. Tias yog vim li cas transformer bushings muaj nyob. Hauv cov ntsiab lus yooj yim, lawv ua zoo li txoj kev muaj kev tiv thaiv hnyav heev uas cia siab - hluav taws xob hluav taws xob nkag mus thiab tawm ntawm lub tank transformer yam tsis tau tig tag nrho lub thawv hlau mus rau qhov muaj kev phom sij.
Xav txog nws zoo li no: tsis muaj bushing, khiav ib txoj hlua nyob ncaj nraim los ntawm lub qhov hauv lub thawv hlau yuav zoo li threading cable los ntawm ntug hlau ntse tsis muaj kev tiv thaiv - tag nrho cov khoom yuav txaus ntshai. Lub bushing yog ib qho kev ua haujlwm siab -tech, super- insulated qhov uas ua kom lub zog nyob qhov twg: hauv tus neeg xyuas pib, tsis xau tawm mus rau lub tank lossis hauv av.
Dab tsi yog sab hauv ntawm transformer?nias ntawm no!
Qhov "Grommet" Trick Ua kom muaj hluav taws xob hauv kev txheeb xyuas
Ntawm nws cov tub ntxhais, lub bushing ua haujlwm zoo li cov roj hmab grommet koj pom kev tiv thaiv cov xov hlau hla ntawm lub rooj lossis vaj huam sib luag. Nyob rau hauv lub bushing koj muaj tiag tiag hlau conductor nqa tam sim no. qhwv ib ncig ntawm nws yog lub cev muaj zog insulating - feem ntau yog ua los ntawm cov plooj (porcelain) lossis cov khoom siv polymer tawv - uas txwv tsis pub hluav taws xob dhia mus rau sab.
Tag nrho cov tsim yog tsim nyob ib ncig ntawm ib tug yooj yim tab sis tseem ceeb lub tswv yim: hluav taws xob xav tau ib tug shortcut, thiab hlau tank yog ib tug heev tempting txoj kev. Lub bushing txoj hauj lwm yog los thaiv qhov shortcut kiag li thiab yuam kom lub hwj chim kom ntws zoo nyob rau hauv txoj kab rau koj lub tsev.

Vim li cas Bushings zoo li accordions
Yog tias koj tau pom, cov bushings no yeej tsis du. Lawv muaj cov kab txawv txawv hu ua "sheds." Muaj ib qho laj thawj zoo rau qhov ntawd. Yog tias qhov chaw tiaj tus, cov dej nag yuav cia li khiav hauv ib daim ntawv txuas ntxiv, tsim txoj hauv kev zoo tshaj plaws rau hluav taws xob nkag mus rau sab nraud thiab ua rau muaj teeb meem.
Cov accordion -zoo li lub tsev ua peb yam tseem ceeb:
Lawv ua txoj kev ntev dua, yog li hluav taws xob muaj lub sijhawm nyuaj dhia hla.
Lawv rhuav cov dej ntws - los nag los ntawm ntug es tsis txhob ua ib zaj duab xis conductive.
Lawv khaws cov hauv qab ntawm cov ridges kuj qhuav txawm nyob rau hauv cov huab cua ntub.
Cov duab ntse no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv siab -voltage bushings, uas xav tau ntau qhov siab ntawm cov sheds piv rau qis -voltage ones.
Porcelain vs. Polymer: Old School vs. New School
Tau ntev, feem ntau cov bushings tau ua los ntawm cov plooj (porcelain) xim av - uas hnyav, ci iab ceramic khoom. Nws yog ib qho nyuaj heev tiv thaiv tshav ntuj, nag, thiab hluav taws xob kev nyuaj siab, thiab nws kav ntau xyoo lawm. Qhov downside? Nws hnyav heev thiab tuaj yeem tawg zoo li iav yog tias raug ntaus los ntawm ib ceg ntoo lossis lawg.
Tias yog vim li cas ntau cov khoom siv tam sim no hloov mus rau kev sib xyaw lossis polymer bushings. Cov grey, rubbery- saib cov insulators yog qhov sib dua, tawv dua, thiab tsis tshua tawg. Lawv ua rau kev txhim kho thiab tu ntau yam kev nyab xeeb thiab yooj yim dua rau cov neeg ua haujlwm.
Dab tsi tshwm sim hauv Bushing?
Nyob rau sab nraud, nws tawm tsam huab cua. Nyob rau hauv, tej yam tau txawm ntau nthuav. Yog tias koj txiav ib qho qhib, koj yuav pom cov khaubncaws sab nraud povtseg ntawm daim ntawv tshwj xeeb thiab cov ntawv ci ua kom nruj ua ke - qhov no yog hu ua capacitive graded construction. Nws pab maj mam tswj cov high voltage kom nws tsis punch ncaj nraim los ntawm lub rwb thaiv tsev.
Muaj ob txoj hauv kev los tiv thaiv cov txheej txheem sab hauv:
OIP (Oil Impregnated Ntawv): Cov txheej txheem ib txwm siv cov roj ntxhia. Nws ua haujlwm zoo tab sis xav tau lub tsev kaw zoo kawg nkaus vim tias muaj qhov xau yog xov xwm phem.
RIP (Resin Impregnated Ntawv): Cov khoom tshiab epoxy version. Nws yog qhov ruaj khov dua, tsis xau, thiab dhau los ua qhov kev xaiv zoo tshaj plaws rau daim phiaj niaj hnub.
Vim li cas Bushings Qee zaum Fail (Qhov teeb meem "Pressure Cooker")
Txawm hais tias tag nrho cov kev txawj ntse no, bushings tsis kav mus ib txhis. Cov hnub kub lub caij ntuj sov ua rau txhua yam sab hauv nthuav dav, tso siab rau cov ntsaws ruaj ruaj - zoo li lub tshuab ua kom siab. Sij hawm dhau mus, cov kab nrib pleb me me tuaj yeem tsim, cia cov dej noo nkag mus rau hauv lub rwb thaiv tsev, nws tsim ib txoj hauv kev zais hluav taws xob uas tuaj yeem ua rau tsis ua hauj lwm tam sim ntawd, sparks, los yog hluav taws xob transformer.
Tias yog vim li cas cov neeg siv hluav taws xob tsis tu ncua xyuas cov cim qhia ntawm qhov teeb meem: qhov txawv txav, cov roj ntws tawm, tawg, lossis av ntau dhau. Lawv kuj ua cov kev ntsuam xyuas tshwj xeeb xws li kev ntsuas hluav taws xob thiab kev saib xyuas ib feem kom ntes tau cov teeb meem ua ntej lawv yuav muaj kev phom sij.
Pom kev noj qab haus huv Bushings hauv koj lub zej zog
Yog li koj tuaj yeem qhia tau li cas yog tias lub bushing zoo nyob hauv av? Nov yog daim ntawv teev npe ceev, tsis raws cai:
Tsis pom cov kab nrib pleb lossis chips
Tsis muaj cov roj tsaus stains khiav mus rau sab
Tsis npog hauv cov av tuab lossis grime
Tsis muaj suab nrov nrov lossis suab nrov
Tom ntej no lub sij hawm koj tawm mus taug kev, muab cov unsung heroes saib sai sai ntawm qhov chaw nyab xeeb. Lawv nyob ntsiag to ua txoj haujlwm nyuaj - khaws cov hluav taws xob ntau kom tswj tau kom lub teeb nyob twj ywm thiab txhua tus nyob nyab xeeb.
Cia li nco ntsoov: saib, tsis txhob kov. Cov khoom no tuav ntau txhiab volts, thiab qhov ntse tshaj plaws uas koj tuaj yeem ua tau yog qhuas txog kev tsim vaj tsev thaum tuav ob txhais taw kom ruaj khov rau hauv av.
