Common Faults Roj Sau Tus Kheej Txias Hom Transformer
Kev ua haujlwm ntawm cov roj puv nws tus kheej txias hom transformer ncaj qha cuam tshuam rau lub zog hluav taws xob zoo ntawm tag nrho lub zog hluav taws xob. Nyob rau hauv kev ua hauj lwm, vim muaj kev txwv ntawm ntau yam, ntau yam txhaum yuav inevitably tshwm sim thaum lub sij hawm ua hauj lwm ntawm lub transformer. Yog tias qhov txhaum me me, lub zog hluav taws xob yuav raug cuam tshuam, thiab tseem ua rau muaj hluav taws xob loj. Yog li ntawd, nws yog ib qho tsim nyog los soj ntsuam cov kev ua txhaum ntawm cov roj-immersed transformers, thiab cia cov tuam txhab tsim hluav taws xob tsom xam cov teeb meem ntawm cov roj-immersed transformer circuits.
Kev cuam tshuam ntawm kev ua txhaum ntawm kev rwb thaiv tsev ntawm cov roj ntim nws tus kheej txias hom transformer:
1. Cov khoom paug tawm ncaj qha los ntawm cov rwb thaiv tsev, yog li cov rwb thaiv tsev puas lawm.
2. Cov ozone thiab nitrogen oxides uas ua los ntawm cov paug chemically corrode lub insulating qhov chaw thiab ua rau thermal puas.
Kev tso tawm ib nrab tsis ua haujlwm
Nyob rau hauv qhov kev txiav txim ntawm qhov hluav taws xob hauv cov qauv insulating, qhov tshwm sim tsis khov kho tshwm sim tshwm sim ntawm ntug ntawm lub qhov, uas yog hu ua ib nrab tawm. Yog vim li cas yog tias muaj roj nyob rau hauv lub qhov los yog kab noj hniav ntawm lub transformer roj, lub dielectric qhov tsis tu ncua ntawm cov roj yog me me, thiab lub zog compressive ntawm cov khoom insulating yuav raug txo, ua rau huab cua sib txawv. Lub zog siv ntawm ib feem ntawm qhov paug tawm tsis yog loj, tab sis yog tias qhov kev tso tawm ib nrab mus ntev ua rau kev puas tsuaj los yog kev puas tsuaj ntawm cov khoom siv roj-immersed transformer, nws yuav dhau los ua kev phom sij loj.
Kev ua tsis tiav vim kev puas tsuaj ntawm rwb thaiv tsev
1, thaum cov roj-eroded transformer installation pendant raug tshuaj xyuas, cov pa roj tau raug rau huab cua thiab noo noo yog generated. Sau cov roj kom tiav kom noo noo nyob ib ncig ntawm qhov chaw insulating.
2, vim yog lub voj voog luv luv ntawm cov khoom siv, yog tias lub Hoobkas rwb thaiv tsev tsis qhuav txaus ua ntej, cov ntawv insulating thiab cardboard uas nqus dej noo yuav tshem tawm cov dej noo tom qab khiav mus rau lub sijhawm, yog li txo qis kev ua haujlwm ntawm lub tshuab hluav taws xob. -voltage winding, yog li ua rau DC to tam sim no.
3, sealing tsis zoo tuaj yeem yooj yim ua rau ya raws nyob rau hauv insulating ib feem ntawm winding.
4, yog hais tias lub ntim ntawm hydrogen thiab carbon monoxide nyob rau hauv lub transformer roj nyob rau hauv lub lag luam yog kuj siab, lub adsorption ntawm gases generated los ntawm cov khoom insulating cov ntaub ntawv los yog stainless hlau kuj yuav tsum tau txiav txim siab nyob rau hauv lub manufacturing txheej txheem.
Roj puv nws tus kheej txias hom transformer manufacturers qhia kev daws teeb meem
(1) Thaum lub substation tshiab tsim, siab thiab tsis tshua muaj hluav taws xob fuses yuav tsum tau muab ntsia rau hauv lub sij hawm raws li cov specifications. Yog tias lub fuse raug hlawv tawm lossis raug nyiag thaum lub sijhawm ua haujlwm ntawm lub tshuab hloov pauv, nws yuav tsum tau hloov tam sim ntawd.
(2) Tsim nyog configuration ntawm high thiab tsawg voltage fuse Cheebtsam:
Transformers uas muaj peev xwm ntau dua 1{{2}0kVA yuav tsum tau nruab nrog lub fuse ntawm 2.0 txog 3.0 npaug ntawm qhov ntsuas tam sim no.
Transformers nrog lub peev xwm qis dua 100kVA yuav tsum tau nruab nrog lub fuse ntawm 1.5 txog 2.0 npaug ntawm qhov ntsuas tam sim no.
(3) Txhim kho lub zog ntsuas lub zog, ntsuas lub nra ib ntus nrog lub clamp galvanometer thaum lub sij hawm ncov, kho lub load kom tsim nyog, thiab tiv thaiv peb-theem kev ua haujlwm tsis sib npaug.
(4) Thaum qhov qis voltage sab voltage ntawm 10kV transformer nyob rau hauv thaj tsam ntawm 7 feem pua ~ -10 feem pua, nws yog feem ntau tsis yooj yim sua kom kho tus kais hloov. Thaum kho tus kais hloov, tus kws tshaj lij yuav tsum ua qhov kev sim hloov.
(5) Tsis tu ncua xyuas seb qhov peb-theem tam sim no sib npaug lossis tshaj qhov ntsuas tus nqi. Yog tias muaj qhov tsis txaus ntseeg loj ntawm peb qhov kev thauj khoom tam sim no, siv sijhawm sijhawm los kho.
(6) Ua ntej lub caij cua daj cua dub los txog txhua xyoo, cov neeg ntes ntawm txhua qhov kev hloov pauv hloov pauv yuav tsum raug xa mus rau qhov chaw kuaj xyuas, thiab lawv yuav tsum tau nruab rau lub sijhawm tom qab dhau qhov kev xeem.
(7) Cov kev sim hauv qab no yuav tsum tau ua ua ntej ua haujlwm:
Load feeb, hloov peb zaug, tsis tuaj yeem siv tsis raug.
Kuaj peb zaug nrog lub pob xeem thiab nws yuav tsum ua haujlwm kom zoo.
Qhov kev xeem tsis kam yog hauv av rau 3 zaug, thiab nws yuav tsum ua haujlwm ib txwm.
(8) Tsis tu ncua ntxuav cov av ntawm qhov chaw ntawm cov khoom siv hluav taws xob faib hluav taws xob, seb puas muaj cov cim flash ntawm lub bushing, seb cov hauv av puas zoo, seb cov hmoov txhuas siv rau hauv av puas muaj cov hlua tsis tawg, desoldering, los yog tawg, thiab cov av tiv thaiv. yuav tsum tau kuaj ntawm 4 cov hauv qab no.
(9) Kev soj ntsuam ntawm cov roj transformer roj to
