Cov ntaub ntawv kawm txog kev daws qhov teeb meem hluav taws xob tsis ua haujlwm ntawm lub tshuab vuam

1. Tsis ruaj tsis khov welding tam sim no
Fault phenomenon
Thaum lub sijhawm ua haujlwm ntawm lub tshuab vuam, qhov vuam tam sim no hloov pauv zoo heev, ua rau lub vuam tsis ruaj khov, tsis sib xws ntawm vuam, thiab qee zaum txawm tias tsis tiav vuam lossis overburning.
Kev daws teeb meem thiab kev daws teeb meem
Ua ntej, xyuas qhov input voltage ntawm vuam transformer. Siv lub voltmeter los ntsuas qhov voltage ntawm thawj sab ntawm lub transformer, thiab pom tias qhov voltage fluctuation ntau tshaj li tus qauv ib txwm (± 5%). Tom qab kev tshuaj xyuas kab, nws tau pom tias lub tshuab vuam tau sib koom lub thawv xa khoom nrog rau lwm cov khoom siv loj hauv kev cob qhia. Thaum lwm yam khoom siv loj pib lossis nres, nws yuav ua rau daim phiaj hluav taws xob hloov pauv.
Txoj kev daws teeb meem yog teeb tsa lub thawv cais rau lub tshuab vuam thiab nruab ib lub zog stabilizer. Lub voltage stabilizer tuaj yeem ua kom ruaj khov ntawm cov khoom siv hluav taws xob hauv qhov ib txwm xav tau los ntawm lub tshuab vuam. Tom qab kev hloov kho, qhov vuam tam sim no rov qab mus rau qhov ruaj khov thiab qhov vuam zoo yog txhim kho.
Lwm qhov ua tau yog tias muaj qhov luv luv hauv zos nyob rau sab hauv winding ntawm vuam transformer. Los ntawm kev ntsuas qhov tseem ceeb ntawm kev tiv thaiv ntawm thawj thiab theem nrab windings ntawm lub transformer, nws tau pom tias tus nqi tsis kam ntawm qhov nruab nrab winding yog qis dua tus nqi tus qauv. Tom qab disassembling lub transformer rau kev soj ntsuam, nws tau pom tias ib co ntawm inter-tig rwb thaiv tsev ntawm lub thib ob winding puas, ua rau ib tug luv luv Circuit Court.
Kho qhov puas winding, rewind lub rwb thaiv tsev puas, thiab reinstall lub transformer tom qab varnishing thiab ziab. Qhov teeb meem ntawm qhov tsis ruaj khov welding tam sim no raug daws.
2. Kev tswj tsis tau Circuit Court
Fault phenomenon
Kev tswj Circuit Court ntawm lub tshuab vuam tsis tuaj yeem ua haujlwm zoo, xws li kev ua haujlwm vuam tsis tuaj yeem ua raws li lub sijhawm teem, lub sijhawm vuam ntev dhau los lossis luv dhau, lossis qhov kev pabcuam vuam tsis tuaj yeem pib.
Kev daws teeb meem thiab kev daws teeb meem
Xyuas cov relay nyob rau hauv lub tswj Circuit Court. Qhib lub txee tswj thiab pom tias qhov taw qhia lub teeb ntawm lub relay tsis nyob. Siv ib tug multimeter los ntsuas qhov tsis kam ntawm relay kauj thiab pom tias qhov kev tiv thaiv yog infinite, qhia tias lub relay kauj yog qhib.
Tom qab hloov lub relay ntawm tib tus qauv, qee qhov haujlwm tau rov qab los, tab sis lub sijhawm vuam tseem tsis raug. Kev tshuaj xyuas ntxiv tau pom tias lub capacitor uas tswj lub sijhawm vuam muaj cov dej xau. Capacitor leakage yuav ua rau lub sijhawm them tsis zoo thiab lub sijhawm tawm, yog li cuam tshuam rau kev tswj lub sijhawm vuam.
Tom qab hloov lub capacitor, tswj Circuit Court rov qab mus rau qhov qub thiab tuaj yeem ua haujlwm vuam raws li lub sijhawm teem.
3. Tsis muaj tam sim no dhau los ntawm electrode
Fault phenomenon
Tom qab lub tshuab vuam pib, tsis muaj tam sim no dhau los ntawm electrode thiab vuam tsis tuaj yeem ua.
Kev daws teeb meem thiab kev daws teeb meem
Ua ntej, xyuas cov kab kev sib txuas ntawm cov electrode thiab cov zis thib ob ntawm lub vuam transformer. Nws tau pom tias lub cable txuas rau electrode puas lawm thiab cov hlau sab hauv tau tawg ib nrab. Qhov no tej zaum yuav tshwm sim los ntawm lub sij hawm ntev mechanical rub thiab hnav.
Tom qab kho qhov puas ntawm lub cable thiab rov txuas nws ruaj khov, lub electrode tseem tsis muaj tam sim no. Tom qab ntawd xyuas lub fuse ntawm qhov tso tawm thib ob ntawm lub vuam transformer thiab pom tias lub fuse tau tawg.
Tom qab hloov lub fuse, cov electrode muaj tam sim no thiab lub vuam tshuab rov ua haujlwm zoo li qub. Lub fuse tej zaum yuav tshwm sim los ntawm ib tug luv luv Circuit Court tshwm sim los ntawm kev puas tsuaj ntawm lub cable thiab dhau tam sim no.
4. Cov khoom xau
Fault phenomenon
Thaum tus neeg teb xov tooj tab tom khiav lub tshuab vuam, nws xav tias muaj hluav taws xob me ntsis. Siv cov cuab yeej siv los kuaj xyuas kom pom, nws tau pom tias cov cuab yeej tau xau.
Kev daws teeb meem thiab kev daws teeb meem
Ua ntej, txiav lub hwj chim ntawm lub tshuab vuam thiab xyuas cov khoom siv hauv av. Nws tau pom tias qhov kev sib txuas hauv av tau xoob, uas tuaj yeem ua rau cov khoom siv tsis tuaj yeem ua rau hauv av ib txwm muaj thaum lub sijhawm ua haujlwm, ua rau cov cuab yeej siv hluav taws xob.
Tom qab rov txuas cov xaim hauv av kom ruaj khov, qhov tshwm sim ntawm qhov xau tau txo qis, tab sis nws tseem muaj. Kev tshuaj xyuas ntxiv ntawm cov hluav taws xob hluav taws xob tau qhia tias lub plhaub insulating ntawm cov khoom siv hluav taws xob (contactor) hauv kev tswj xyuas hluav taws xob tau puas lawm, thiab qhov chaw nyob sab hauv yog me ntsis hauv kev sib cuag nrog cov khoom siv plhaub.
Tom qab hloov lub contactor, cov xau ntawm lub tshuab vuam tau ploj mus, thiab cov khoom siv tuaj yeem siv tau zoo.
