Tej zaum koj yuav pom tias koj lub cuab yeej nyob twj ywm tsis txhob nyem, tswj vaj huam sib luag mus tsaus ntuj, lossis koj hnov qab qee yam hlawv. Qee zaum, koj txawm pom pom kev puas tsuaj ntawm lub relay. Cov tsos mob burnt tawm no tuaj yeem pab koj pom qhov teeb meem sai. Ua ntej, saib rau tej yam tshwm sim ntawm tshav kub los yog discoloration nyob ze ntawm lub relay. Kev ua ceev ceev ua rau koj lub tshuab hluav taws xob muaj kev nyab xeeb.
Tswv yim:Koj tsis xav tau cov cuab yeej tshaj lij los pib- cov tshev yooj yim ua haujlwm rau cov neeg pib tshiab feem ntau.
Ntsiab Cai
Mloog rau nias thaum koj qhib koj lub cuab yeej. Yog tias koj tsis hnov dab tsi, lub relay coil yuav raug hlawv.
Nrhiav kev puas tsuaj uas koj tuaj yeem pom, xws li cov xim hloov lossis tsw ntxhiab tsw. Cov paib no feem ntau txhais tau tias koj yuav tsum tau hloov lub relay.
Siv lub multimeter los ua qhov kev xeem txuas ntxiv. Qhov no xyuas seb lub relay coil ua haujlwm. Yog tias koj tsis tau txais kev nyeem ntawv, lub kauj yuav raug hlawv tawm.
Nco ntsoov tua lub hwj chim ua ntej koj saib lossis hloov lub relay. Qhov no ua rau koj muaj kev nyab xeeb los ntawm hluav taws xob shocks.
Txhawm rau kom tsis txhob hlawv yav tom ntej, siv cov tshuaj tiv thaiv hluav taws xob. Tsis tas li ntawd, xyuas koj cov relays ntau zaus rau cov cim ntawm kev hnav.
Burnt Out Cov tsos mob ntawm Relay Coil
Tsis Nyem Suab
Lub relay yuav tsum ua lub suab nias thaum nws tig rau. Yog tias koj tsis hnov ib nias, qhov no yog ib qho mob tshwm sim. Silence txhais tau hais tias lub kauj tsis tuaj yeem txav lub armature. Tshawb xyuas lub vaj huam sib luag yog tias nws tsis teeb. Lub relay kauj yuav tawg. Qee zaum, lub kauj kub kub tawm yog tias qhov hluav taws xob siab dhau. Koj tuaj yeem pom tias qhov relay tsis ua haujlwm zoo yog tias lub tshuab hluav taws xob tsis txuas zoo.
Nco tseg:Yog hais tias lub relay nyob twj ywm, nws feem ntau txhais tau hais tias muaj teeb meem. Nco ntsoov mloog rau qhov nias thaum koj qhib koj lub cuab yeej.
Device Tsis Powering On
Yog hais tias lub relay coil hlawv tawm, koj lub cuab yeej yuav tsis qhib. Qhov no yog lwm qhov tseeb burnt tawm cov tsos mob. Koj nias qhov hloov, tab sis tsis muaj dab tsi tshwm sim. Lub relay tsis tuaj yeem kaw lub voj voog. Saib rau xeb lossis corrosion ntawm cov terminals. Cov dej noo tuaj yeem ua rau corrosion thiab luv luv Circuit Court. Cov kub kub ua rau lub kauj tiv thaiv ntau dua thiab tuaj yeem ua rau burnout. Qhov kub qis ua rau qhov chaw nkig thiab ua rau dej tsim.

Burnt Smell lossis pom kev puas tsuaj
Ib tug burnt tsw yog ib tug ntshiab burnt tawm tsos mob. Koj tuaj yeem pom cov ntxhiab tsw zoo nyob ze ntawm lub relay. Qee zaum, koj pom kev puas tsuaj xws li cov yas yaj lossis cov yas tsis muaj xim. Burnt lossis corroded hu tuaj yeem tshwm sim. Arcing los ntawm cov khoom hnyav tuaj yeem ua rau cov pa roj carbon dub. Plua plav, gases, thiab ya raws kuj tuaj yeem ua rau corrosion.
Hlawv lossis corroded hu
Cov roj carbon dub txheej ntawm kev sib cuag
Melted los yog discolored yas
Cov cim ntawm arcing
Yog tias koj pom lossis hnov cov paib no, ua kom nrawm. Tua lub hwj chim thiab xyuas lub relay. Cov tsos mob burnt tawm no txhais tau hais tias lub kauj yuav tsum tau hloov.
Cov kauj ruam kuaj mob
Kev tshuaj xyuas qhov muag
Pib los ntawm saib ze ntawm lub relay. Koj tuaj yeem pom ntau cov tsos mob hlawv nrog koj ob lub qhov muag thiab qhov ntswg. Saib xyuas cov cim no:
Relay rooj plaub hloov xim, xws li xim av lossis xim dub nyob ze ntawm lub kauj.
Cov ntaub ntawv yas melts, khoov, los yog bulges. Qhov no feem ntau txhais tau hais tias lub relay tau kub heev.
Ib tug muaj zog burnt tsw los ntawm yas los yog kua roj vanish. Qhov no tuaj yeem qhia tias rwb thaiv tsev puas lawm.
Yog tias koj pom ib qho ntawm cov cim no, lub relay tej zaum yuav tsum tau hloov. Relays feem ntau ua tsis tau vim yog qhov tam sim no ntau dhau los yog qhov hluav taws xob, hnub nyoog laus, lossis tej yam xws li plua plav thiab av noo. Qee zaum, qhov tsis zoo lossis kev laus kuj ua rau muaj teeb meem.
Tswv yim:Nco ntsoov saib kev puas tsuaj ua ntej siv cov cuab yeej.
Kev xeem txuas ntxiv
Ib qho kev ntsuas txuas ntxiv xyuas seb lub relay coil tseem ua haujlwm. Siv lub multimeter teeb rau kev txuas ntxiv lossis hom tsis kam. Muab cov probes rau ntawm cov relay coil terminals. Yog hais tias lub 'meter' qhia tsis muaj dab tsi los yog infinite kuj, lub kauj yog burnt tawm. Yog tias koj pom qhov kev nyeem ntawv ib txwm, lub kauj yuav tseem ua haujlwm.
Feem ntau yog vim li cas rau qhov kev sim ua tsis tiav yog overvoltage, overcurrent, thiab kev co. Cov no tuaj yeem ua mob rau lub kauj thiab ua rau burnout. Nov yog yuav ua li cas cov teeb meem no cuam tshuam rau relay:
|
Qhov xwm txheej |
Cov nyhuv ntawm Relay Coil Burnout |
|---|---|
|
Overvoltage |
tuaj yeem tawg rwb thaiv tsev thiab ua rau luv luv, ua rau burnout. |

Yuam kev & Kev ntseeg yuam kev
Cov tsos mob tsis meej pem
Qee zaum, koj yuav xav tias lub kauj tawg. Tab sis lwm qhov chaw tuaj yeem ua rau muaj teeb meem. Ntau tus neeg ntseeg tias lub kauj yog ib txwm muaj teeb meem yog tias lub cuab yeej ua tsis tiav. Qhov teeb meem tiag tiag tuaj yeem yog nrog cov neeg sib txuas lus. Kev sib cuag tsis ua haujlwm feem ntau tshwm sim los ntawm hluav taws xob arcing lossis vuam. Cov teeb meem no tuaj yeem zoo li coil burnout yog tias koj tsis kuaj xyuas zoo. Ib txwm sim ob lub kauj thiab cov neeg sib cuag. Siv ib lub multimeter los kuaj xyuas qhov txuas ntxiv. Tsis tas li ntawd, xyuas qhov voltage thiab qhov ntsuas tam sim no. Ntau dhau voltage tuaj yeem hlawv tawm lub kauj. Tiv tauj faults xav tau kev kho sib txawv.
Tswv yim:Nug koj tus kheej yog tias qhov teeb meem nrog lub kauj lossis cov neeg sib cuag ua ntej hloov dab tsi.
Tsis quav ntsej tej yam yooj yim
Koj tuaj yeem nco cov lus qhia yooj yim yog tias koj tsis saib ze. Qee tus neeg hla qhov pib thiab mus ncaj nraim mus rau qhov kev xeem siab. Nov yog cov cim qhia yooj yim uas koj yuav tsum tsis txhob quav ntsej:
Discoloration, hlawv, los yog corrosion ntawm lub relay los yog lub rooj tsavxwm
Hlawv, pitted, los yog dub relay hu
Charred kab los yog tawg solder daim npog qhov ncauj nyob ib ncig ntawm lub relay
Cov paib no feem ntau txhais tau tias muaj overcurrent lossis overheating. Yog tias koj pom lawv, kos lub relay tam sim ntawd. Kev saib nrawm tuaj yeem txuag lub sijhawm thiab tiv thaiv kev ua yuam kev.
Siv cov cuab yeej siv tsis raug
Koj yuav tsum siv koj cov cuab yeej kom raug. Qee tus neeg teeb tsa lawv lub multimeter mus rau hom tsis raug lossis txuas cov kev sojntsuam tsis raug. Qhov no tuaj yeem muab cov ntawv nyeem cuav. Ib txwm nyeem cov cuab yeej cov lus qhia ua ntej kev sim. Tsis txhob hla qhov kev tshuaj ntsuam pom ua ntej siv multimeter. Yog tias koj tsuas yog siv cov cuab yeej xwb, koj yuav tsis pom kev puas tsuaj.

Cov kauj ruam tom ntej tom qab kuaj mob
Kev tshem tawm nyab xeeb
Koj yuav tsum tshem tawm cov burnt tawm relay coil yam xyuam xim. Ua ntej, tua tag nrho cov hwj huam rau lub cuab yeej. Tos kom txog thaum txhua lub teeb tawm. Siv cov cuab yeej insulated kom koj tsis txhob poob siab. Ua tib zoo rub lub relay ntawm nws lub qhov (socket) los yog unscrew nws los ntawm lub rooj tsavxwm. Tsis txhob thab lossis yuam nws tawm. Yog tias nws yuav tsis txav mus, nrhiav cov clips ntxiv lossis cov ntsiab lus solder. Nco ntsoov khaws koj txhais tes kom qhuav thiab hnav hnab looj tes tiv thaiv. Muab cov qub relay tso rau hauv lub thawv ruaj ntseg kom pov tseg.
Tswv yim:Nco ntsoov xyuas tias lub hwj chim tsis raug ua ntej kov cov xov hlau lossis qhov chaw.
Hloov Cov Lus Qhia
Thaum koj xaiv lub relay coil tshiab, xyuas kom nws haum koj lub cuab yeej. Xaiv ib lub relay uas ua haujlwm nyob rau hauv qhov kub thiab txias uas koj yuav siv nws. Tus tshiab relay yuav tsum haum lub qhov (socket) los yog mounting qhov. Muab lub relay ncaj thiab nruj kom nws tsis txhob xoob. Khaws thaj chaw kom huv si kom cov plua plav lossis dej tsis ua teeb meem. Nov yog qee cov lus qhia zoo:
Xaiv ib lub relay uas ua haujlwm nyob rau hauv qhov kub thiab txias.
Muab lub relay nyob rau hauv txoj cai kom tsis txhob overheating.
Khaws lub relay kom huv si ntawm plua plav thiab dej.
Tom qab koj muab tso rau hauv lub relay tshiab, sim lub cuab yeej. Mloog rau qhov nias thiab saib seb lub cuab yeej tig rau. Yog tias koj pom lossis hnov qhov txawv txawv, tua lub zog thiab xyuas koj txoj haujlwm.
Tiv thaiv yav tom ntej Burnout
Koj tuaj yeem ua tej yam kom txwv koj cov relay coil tshiab kom tsis txhob hlawv dua. Siv cov hluav taws xob stabilizers thiab surge protectors kom txo hluav taws xob. Lubricate txav qhov chaw kom lawv txav tau yooj yim. Tshawb xyuas cov rwb thaiv tsev tiv thaiv thiab siv thermal imaging kom pom qhov kub kub thaum ntxov. Tau txais relays nrog siab - kub rwb thaiv tsev kom ntev dua. Ib txwm ua raws li kev cai thoob ntiaj teb rau relay installation thiab siv.
