Common Problems with Electrical Load Break Switch & How to Fix Them

Hauv lub zog faib hluav taws xob, lubKev Hloov Pauv Hluav Taws Xobyog ib qho tseem ceeb, siv dav hauv cov xwm txheej hauv tsev, kev lag luam thiab kev lag luam los tswj cov khoom siv tam sim no thiab xyuas kom muaj kev nyab xeeb ntawm lub zog fais fab. Tsab xov xwm no tsom mus rau nws cov qhov tsis zoo, tshuaj xyuas cov laj thawj thiab muab cov kev daws teeb meem, kev txawj txij nkawm thiab kev tiv thaiv, pab cov kws kho mob daws teeb meem sai thiab zam kev phom sij rau kev nyab xeeb.

1. Cov Kev Ua Txhaum Cai thiab Cov Kev Daws Teeb Meem Sai

LubKev Hloov Pauv Hluav Taws Xobfeem ntau yuav muaj qhov tsis zoo vim siv ntev, ib puag ncig thiab kev ua haujlwm tsis raug. Nov yog 5 qhov tsis zoo thiab kev kho uas feem ntau tshwm sim:

1.1 Teeb Meem Kev Tawg

Feem ntau qhov kev ua txhaum cai yog los ntawm kev thauj khoom ntau dhau, luv luv Circuit Court, kev sib cuag tsis zoo lossis kev ua tsis tiav ntawm lub cuab yeej ua txhaum cai. Kev kho: Txiav cov khoom thauj kom kuaj xyuas qhov kev thauj khoom ntau dhau; siv lub multimeter los nrhiav thiab kho cov luv luv circuits; ntxuav lossis hloov cov contacts; tshuaj xyuas thiab hloov cov khoom ua txhaum cai.

1.2 Kev Sib Txuas Lus Tsis Zoo

Cov tsos mob suav nrog lub qhov hloov kub dhau, suab arc thiab lub zog tsis tu ncua. Kev daws teeb meem: Tua lub zog, xyuas seb puas muaj oxidation lossis cov xov hlau xoob; txhuam cov neeg sib cuag nrog ntawv xuab zeb; nruj cov terminals thiab sim tom qab kho.

1.3 Teeb Meem Kub Dhau

Kev kub dhau, yog ib qho txaus ntshai heev, yog tshwm sim los ntawm kev sib cuag tsis zoo, kev ua haujlwm ntau dhau, kev tso cua sov tsis zoo lossis qhov kub thiab txias heev. Tiv thaiv los ntawm kev xaiv cov qhov hloov pauv kom haum thiab ua kom muaj cua nkag; kho los ntawm kev txias lub qhov hloov pauv, daws teeb meem thiab hloov cov khoom puas tsuaj yog tias xav tau.

1.4 Kev ua haujlwm tsis zoo

Cov tes tuav uas daig lossis kev siv nyuaj yog los ntawm kev siv tshuab tsis zoo, cov khoom txawv teb chaws, xeb lossis cov khoom xoob. Ntxuav lub qhov hloov, siv roj nplua nyeem, tshem tawm xeb thiab zawm cov khoom xoob; hloov cov khoom uas puas lawm yog tias tsim nyog.

1.5 Teeb Meem Txog Kev Xaus Dej

Yog xau, tej zaum yuav muaj hluav taws xob poob. Siv cwj mem hluav taws xob los yog multimeter los nrhiav. Kho: Txiav hluav taws xob, xyuas thiab hloov cov khoom rwb thaiv tsev uas puas lawm, xyuas kom lub grounding zoo li qub, thiab sim tom qab kho.

2. Phau Ntawv Qhia Txog Kev Teeb Meem

Ua raws li cov kauj ruam "los ntawm qhov yooj yim mus rau qhov nyuaj": Npaj cov cuab yeej thiab txiav hluav taws xob; tshuaj xyuas sab nraud, ua qhov kev sim qhib hluav taws xob, rhuav tshem kom pom qhov tsis zoo; sim thiab txheeb xyuas tom qab kho kom ntseeg tau tias ua haujlwm li qub.

3. Kev Txij Nkawm Mus Ntev

Saib xyuas txhua 3-6 lub hlis (chaw nyob/chaw lag luam) lossis 1-3 lub hlis (chaw ua haujlwm). Ntxuav lub qhov hloov, xyuas cov khoom sib txuas thiab cov xov hlau, sim lub tes tuav; hnav cov khoom siv rwb thaiv tsev thaum lub sijhawm saib xyuas thiab ua haujlwm kom raug kom ntev lub neej kev pabcuam.

4. Kev Nkag Siab Yuam Kev Feem Ntau

Tsis txhob yuam kom qhib thiab kaw nrog lub nra hnyav, tsis quav ntsej txog kev tawg, kev teeb tsa tsis raws cai, xaiv cov qhov hloov tsis zoo, ua rau nws tsis meej pem nrog cov khoom siv hluav taws xob, thiab tsis quav ntsej txog cov yam ntxwv ib puag ncig. Xaiv cov qhov hloov uas tau ntawv pov thawj thiab ua haujlwm raws li tus qauv.

5. Cov Ua Rau Muaj Qhov Tsis Zoo Thiab Kev Tiv Thaiv

Qhov ua yuam kev yog los ntawm qhov tsis zoo ntawm lub khawm hloov, kev xaiv tsis raug, kev ua haujlwm lossis kev saib xyuas, thiab qhov chaw nyob tsis zoo. Tiv thaiv los ntawm kev xaiv cov khawm hloov zoo, kev ua haujlwm kom raug, kev saib xyuas tsis tu ncua thiab kev txhim kho qhov chaw ua haujlwm.

6. Xaus Lus

LubKev Hloov Pauv Hluav Taws Xobyog qhov tseem ceeb rau kev ruaj khov ntawm lub zog fais fab. Kev paub txog nws cov kev daws teeb meem thiab kev txawj txij nkawm yuav pab txo qhov ua yuam kev, ua kom lub neej ua haujlwm ntev dua thiab ua kom muaj kev nyab xeeb.
