Kev tuav ntawm damp magnesium oxide rwb thaiv tsev nyob ntawm qhov℃ntawm noo noo. Tus yuam sij yog tam sim ntawd disconnect lub hwj chim thiab sim cov rwb thaiv tsev tsis kam. Yog qhov tsis kam<10 MΩ, the heating element must be replaced; if it is between 10–100 MΩ, drying or partial repair can be attempted as an emergency measure.
1. Kev tshem tawm hluav taws xob tam sim thiab kev sib cais kev nyab xeeb
Yog tias cov cuab yeej tshaj tawm txog kev tiv thaiv kev tiv thaiv, kev ua txhaum hauv av, lossis cua sov txawv txav, tam sim ntawd txiav lub hwj chim; tshem lub rhaub tsuas yog tom qab nws tau txias tag kom tsis txhob muaj luv luv Circuit Court lossis hluav taws xob poob siab los ntawm kev ua haujlwm nyob.
2. Kev ntsuas hluav taws xob nrawm
Siv 2500V megohmmeter los ntsuas qhov rwb thaiv tsev ntawm cov cua sov thiab cov casing:
<10 MΩ: Severely damp; do not continue use;
10-100 MΩ: Kev ntsuas kev kho yuav raug sim; mus rau kauj ruam tom ntej.
3. Kev Kho Mob Thaum Muaj Xwm Ceev rau me ntsis mus rau nruab nrab Moisture Infestation
Tsawg-Tsub Ci + Tus Kheej-Tswv Cuab Dehumidification (Ntawm -Site Feasibility)
Muab cov khoom cua sov tso rau hauv qhov cub thiab ua ntej- ci ntawm 80℃rau 2 teev;
Ua kom kub rau 120℃thiab tuav 4 teev;
Tom qab tshem tawm, siv 50% ntawm qhov ntsuas hluav taws xob rau 30 feeb kom ntxiv dehumidify siv tus kheej - cua sov;
Tom qab txias, rov ua dua lub rwb thaiv tsev; Ntau dua lossis sib npaug rau 100 MΩ qhia tau tias ua tiav.
Tsis txhob ncaj qha ci ntawm qhov kub siab kom tiv thaiv cov dej vapor siab los ntawm kev ua rau lub plhaub lub plhaub kom bulge.
Kev txiav ib nrab thiab rov txuas dua (tsuas yog rau Moistened Terminals)
Txiav tsawg kawg 50mm sab hauv los ntawm qhov chaw noo noo;
Re- crimp cov coj, kom ntseeg tau tias tiv thaiv kev tiv thaiv tsawg dua lossis sib npaug rau 0.03Ω;
Multi- txheej sealing: qhwv nrog cov ntaub nplaum tsis muaj dej → Siv cov cua sov shrink tubing thiab cua sov kom ntsws → xaiv silicone txheej rau kev tiv thaiv zoo dua;
Lub raj kho yuav tsum xeem dhau 2500V rwb thaiv tsev.
Qhov no yog ib qho kev daws teeb meem ib ntus; nws raug pom zoo los hloov tag nrho cov raj kom ntev -lub sij hawm ruaj khov.
4. Kev Tiv Thaiv Thaum Muaj Xwm Ceev rau Kev Tiv Thaiv Kabmob hnyav
Cov khoom yog irreparable yog hais tias ib yam ntawm cov nram qab no tej yam kev mob tshwm sim:
Rwb thaiv tsev tsis kam <10 MΩ;
Bulging, tawg, los yog muaj cov muaju dawb (Mg(OH)₂) ntawm lub casing;
Carbonization vim siab -kub laus.
Hauv qhov no, koj yuav tsum:
Tam sim ntawd hloov cov khoom cua sov;
Los yog xa rov qab mus rau lub Hoobkas rau kev refilling thiab sintering.
