Kev kho ntawm qhuav Transformer 3 Theem
Txij li thaum lub coil ntawm lub transformer yuav sov thaum lub sij hawm ua hauj lwm, nws yog ib qhov tsim nyog yuav tau ua kom txias ntsuas. Lub peev xwm me me tuaj yeem ua kom qhuav transformer 3 theem, nrog cua txias lossis cua txias. Loj-muaj peev xwm transformers feem ntau siv roj raws li qhov nruab nrab cua txias thiab yuav tsum tau yuam kom cua txias.
Thaum lub sijhawm ua haujlwm ntawm lub tshuab hluav taws xob qhuav 3 theem, lub hauv paus thiab theem nrab coils thiab cov tub ntxhais sib nqus yuav tsim kom muaj cua sov. Cov roj transformer ntws los ntawm cov khoom no kom tshem tawm cov cua sov los ntawm kev siv hluav taws xob, thiab tom qab ntawd dissipates cov cua sov mus rau hauv huab cua los ntawm lub radiator. Hauv lwm lo lus, kev ua haujlwm ntawm lub tshuab hloov pauv yog kev sib koom ua ke ntawm qhov sib txawv ntawm cov khoom siv hluav taws xob thiab cov cua sov dissipation. Obviously, tus nqi ntawm tshav kub generated los ntawm lub transformer yog proportional rau qhov luaj li cas ntawm lub load, thiab lub tshav kub dissipation yog ncaj qha cuam tshuam rau ib puag ncig ib puag ncig.
Amorphous alloy transformers yog ob qho tib si txuag hluav taws xob thiab kev lag luam. Nws qhov tseem ceeb tshaj plaws yog tias tsis muaj qhov poob qis heev, uas tsuas yog kwv yees li 20 feem pua ntawm S9 series roj-immersed transformers. Kev faib tawm transformer nrog cov txiaj ntsig zoo tshaj plaws yog qhov tshwj xeeb tshaj yog tsim rau cov chaw uas tsis tshua muaj nqi xws li cov kab hluav taws xob nyob deb nroog.
Cov lus ceeb toom ntawm kev saib xyuas ntawm qhuav transformer 3 theem hauv kev ua haujlwm:
Overload ua haujlwm ntawm qhuav-hom faib transformers
Transformer overload ua hauj lwm txhais tau hais tias lub load tam sim no tshaj qhov ntsuas tam sim no ntawm transformer. Nyob rau hauv ib txwm muaj xwm txheej, thaum lub transformer yog khiav ntawm ib tug me me load, nws cov ntaub ntawv insulating tsis tau tag nrho nws lub luag hauj lwm. Thaum lub sijhawm ua haujlwm tsis tu ncua, lub tshuab hloov pauv yuav tsim kom muaj qhov kub thiab txias, uas yuav ua rau lub rwb thaiv tsev winding hardened thiab poob tawm, uas ua rau inter-tig luv luv Circuit Court; Nyob rau tib lub sij hawm, cov roj transformer tsim Sludge accumulates nyob rau hauv lub tank phaj, winding thiab hlau core, uas ua rau tsis zoo tshav kub dissipation ntawm transformer roj. Lub voj voog vicious no tsis tsuas yog cuam tshuam rau lub neej ntawm transformer, tab sis kuj ua rau muaj kev sib tsoo xws li high-voltage breakdown thiab transformer burnout. Yog li ntawd, peb-theem load tam sim no yuav tsum tau saib ntau zaus. Peb-theem load tam sim no yuav tsum zoo ib yam, yog tias muaj qhov sib txawv, nws yuav tsum tsis pub tshaj 10 feem pua.
Lub suab txawv txawv ntawm kev faib transformer
Thaum alternating tam sim no dhau los ntawm transformer windings, ib txwm thiab niaj hnub "humming" suab tshwm sim vim lub ntuj vibration ntawm cov tub ntxhais hlau. Yog tias muaj lub suab txawv txav, koj yuav tsum nrhiav qhov laj thawj thiab ceeb toom rau lub tuam tsev muaj feem cuam tshuam rau lub sijhawm. Lub suab kuj txawv thaum lub transformer yog unloaded thiab loaded. Raws li lub suab txawv txav piv nrog yav dhau los, qhov laj thawj tuaj yeem pom ua ntej nws tuaj yeem muab tso rau hauv kev ua haujlwm.
Seb cov roj theem ntawm lub tshuab ziab khaub ncaws qhuav 3 theem yog qhov qub, thiab seb puas muaj qhov xau, roj to lossis xim roj tsis zoo
Muaj ntau ntau yam ua rau cov roj qib poob. Vim tsis zoo welding zoo thiab tsis zoo sealing, radiating kav, li qub, lub thawv npoo, thiab lwm yam yog nquag mus seepage thiab roj to. Thaum cov roj theem poob qis hauv qab lub hau ntawm lub tshuab hloov pauv, qhov chaw sib cuag ntawm cov roj thiab cov huab cua nce, thiab nws yooj yim rau oxidize thiab deteriorate thiab nqus cov dej noo hauv huab cua, uas ua rau txo qis hauv compressive lub zog ntawm cov roj. roj, yog li rhuav tshem cov rwb thaiv tsev kev ua haujlwm ntawm winding. Thaum cov roj tsis txaus yog qhov hnyav, cov rwb thaiv tsev ntawm cov khoom siv hluav taws xob ntawm lub transformer mus rau hauv av thiab ib leeg yog txo, uas ua rau cov paug tawm ntawm cov theem los yog hauv av. Yog tias koj txuas ntxiv siv nws nyob rau lub sijhawm no, cov roj transformer yuav tsis tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem tuaj yeem ua rau lub tshuab hluav taws xob hloov pauv cov roj kub kub nce siab, ua kom lub neej luv luv lossis tseem kub hnyiab.
Kev tu tsis tu ncua ntawm kev faib khoom transformers
Tsis tu ncua ntxuav cov av ntawm lub transformer faib, xyuas seb lub bushing puas muaj flashover tawm, seb lub hauv av puas zoo, seb puas muaj disconnection, de-soldering, los yog tawg, thiab tsis tu ncua co lub grounding kuj, thiab nws cov nqi kuj tsis ntau tshaj. 4Ω (muaj peev xwm 100 kVA thiab siab dua) lossis 10Ω (muaj peev xwm tsawg dua 100 kVA), lossis siv cov kev ntsuas tiv thaiv fouling thiab nruab ib lub kaus mom tiv thaiv fouling. Thaum txuas thiab dismantling cov hlau lead nyob ntawm lub transformer tis, nruj me ntsis raws li cov txheej txheem kev khiav hauj lwm kom tsis txhob muaj kev puas tsuaj ntawm cov hlau lead.
Seb puas muaj kev puas tsuaj, rupture thiab paug kab nyob rau hauv insulating bushing ntawm tis transformers
Yog hais tias lub tes tsho insulating tsis tau ntxuav kom ntev, los yog muaj cov kab nrib pleb thiab paug tawm, nyob rau hauv cov huab cua los nag los yog pos huab, cov xau tam sim no ntawm lub tes tsho insulating yuav nce vim cov av noo, rwb thaiv tsev yuav poob, thiab flashover. yuav tshwm sim rau hauv av. Tsis tas li ntawd, kev fouling hnyav ntawm lub tes tsho insulating, nrog rau cov tawg tawg loj thiab tawg ntawm lub tes tsho insulating, tuaj yeem ua rau flashover lossis tawg tawg. Txhawm rau daws qhov tshwm sim no, ntxiv rau kev soj ntsuam lub tes tsho insulating nws tus kheej, peb kuj yuav tsum tau ua tib zoo mloog rau txoj cai ntawm kev sib kis ntawm lub tes tsho, xws li cua kev taw qhia, ib puag ncig ib puag ncig, thiab lwm yam, kom ua haujlwm zoo ntawm kev tu.
