Lub kauj ntawm cov roj-immersed transformer yog ib qho cuab yeej tseem ceeb rau cov roj-immersed transformer. Lub kauj ntawm cov roj-immersed transformer feem ntau muaj ib lossis lwm qhov teeb meem. Lub kauj ntawm cov roj-immersed transformer tseem nyob rau hauv tus txheej txheem ntawm kev txij nkawm. Yuav tsum tau ua tib zoo saib xyuas, kev saib xyuas cov roj-immersed transformer coil xav kom txhua tus neeg yuav tsum xyuam xim rau cov haujlwm hauv qab no:
(1) Ua ntej xyuas seb lub rwb thaiv tsev winding puas laus thiab puas. Feem ntau, siv koj cov ntiv tes los kov qhov chaw ntawm lub rwb thaiv tsev winding thiab saib cov kev hloov pauv. Yog tias cov xim rwb thaiv tsev yog qhov tsaus me ntsis thiab yuav tsis tawg vim yog cov ntiv tes siab, nws qhia tau tias cov rwb thaiv tsev nyob hauv qhov zoo; ntawm qhov tsis sib xws, cov rwb thaiv tsev yuav tsim cov kab nrib pleb me me los yog rwb thaiv tsev tom qab nias nrog koj cov ntiv tes Cov kev ntxhib los mos yog tawv thiab nkig, thiab xim yog tsaus, qhia tias tsis zoo rwb thaiv tsev, thiab yuav tsum tau soj ntsuam ntxiv.
(2) Ntsuas cov nqi hluav taws xob tiv thaiv ntawm lub winding nrog megohmmeter, thiab sib piv cov nqi no nrog cov nqi hluav taws xob tiv thaiv kev ntsuas thawj zaug ua ntej cov roj-immersed transformer muab tso rau hauv kev ua haujlwm. Yog hais tias cov rwb thaiv tsev tsis kam ntawm winding yog qis dua qhov chaw tsim tshuaj ntsuam thaum lub sijhawm ua haujlwm Yog tias tus nqi yog 70%, qhov rwb thaiv tsev ntawm winding ntawm cov roj-immersed transformer yog suav tias yog qhov tsis zoo; Yog hais tias qhov txo qis hauv rwb thaiv tsev tsis yog tshwm sim los ntawm damp winding, qhov ntsuas nruab nrab ntawm cov rwb thaiv tsev thiab tiv taus qhov ntsuas hluav taws xob tuaj yeem ua tiav los txiav txim siab ntxiv qhov ntsuas hluav taws xob ntawm qhov cua, thiab tom qab ntawd ua nrog.
(3) Muaj ob qhov xwm txheej rau cov roj-immersed transformers uas raug kaw los ntawm kev ua ntawm cov roj relay: ib qho yog luv luv ntawm winding lem los yog txheej. Koj tuaj yeem ua ntej ntsuas qhov DC tsis kam ntawm txhua theem sib cais thiab sib piv cov ntaub ntawv xeem rau txhua qhov sib txawv. Tom qab ntawd dhau qhov ntsuas hluav taws xob ntawm lub winding los ua qhov ntsuas tsis muaj load. Yog tias muaj qhov luv luv ntawm kev hloov pauv lossis txheej txheej, lub voj voog luv luv yuav ua kom muaj cua sov thiab cov pa luam yeeb, uas yuav ua rau qhov kev puas tsuaj loj. Yog tias qhov txhaum tsis tuaj yeem tshem tawm los ntawm kev kho cov txheej txheem, ib feem lossis tag nrho cov windings yuav tsum tau hloov. Qhov thib ob yog qhov tsis ua haujlwm ntawm winding disconnection. Ua ntej tshaj plaws, DC tsis kam ntawm txhua theem winding yuav tsum tau kuaj. Tom qab kev sib piv cov lej, cov theem faulty tuaj yeem txiav txim siab, thiab cov hlau tawg tuaj yeem nrhiav tau los kho lossis hloov ib feem ntawm winding coil.
Cov saum toj no yog lub ntsiab kev khiav hauj lwm txoj kev thiab txoj kev rau coil txij nkawm feem ntau nyob rau hauv roj-immersed transformers
