Lub Luag Haujlwm ntawm Cov Hluav Taws Xob Me Me hauv Cov Txheej Txheem Tiv Thaiv Xob Ntxig thiab Cov Lus Qhia Txog Kev Txhim Kho Yav Tom Ntej

Cov Miniature Circuit Breakers (MCBs) ua haujlwm ua cov khoom tseem ceeb hauv cov txheej txheem tiv thaiv hluav taws xob niaj hnub no, tshwj xeeb tshaj yog hauv cov ntawv thov tiv thaiv xob laim. Daim ntawv no tshuaj xyuas lub luag haujlwm tseem ceeb ntawm MCBs hauv kev sib koom tes ntawm cov khoom siv tiv thaiv hluav taws xob (SPD) thiab tshawb nrhiav cov tswv yim txhim kho tshiab.YUYE Electric Co., Ltd.,ua tus thawj coj hauv kev lag luam hauv kev siv tshuab tiv thaiv hluav taws xob, tau tsim cov kev daws teeb meem MCB siab heev uas ua rau muaj kev ntseeg siab ntawm lub kaw lus tiv thaiv xob laim.

1. Kev Taw Qhia
Xob laim ua rau muaj kev phom sij loj heev rau kev teeb tsa hluav taws xob, ua rau cov khoom siv puas tsuaj, poob cov ntaub ntawv, thiab muaj kev phom sij rau kev nyab xeeb. Thaum cov khoom siv tiv thaiv hluav taws xob (SPDs) tsim kev tiv thaiv tseem ceeb, cov khoom siv hluav taws xob me me ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tiv thaiv xob laim. YUYE Electric txoj kev tshawb fawb qhia tau hais tias MCBs uas tau xaiv thiab sib koom ua ke zoo tuaj yeem txhim kho kev tiv thaiv kab ke kom zoo txog li 40%.

2. Cov Haujlwm Tseem Ceeb ntawm MCBs hauv Cov Txheej Txheem Tiv Thaiv Xob laim

2.1 Kev Tiv Thaiv Overcurrent Thaum Muaj Xwm Txheej Surge
Cov MCBs muab kev tiv thaiv tseem ceeb thaum SPDs ntsib kev kub ntxhov. YUYE Electric cov kev sim hauv chaw kuaj mob qhia tau tias lawv cov MCBs tsim tshwj xeeb tuaj yeem cuam tshuam cov hluav taws xob txog li 10kA hauv 5ms, sai dua li cov breakers ib txwm muaj.

2.2 Kev Tiv Thaiv SPD thaub qab
Lub tuam txhabMCB-SPD kev sib koom tes ua kom ntseeg tau tias:

Kev xaiv tripping thaum lub sijhawm overvoltages ntev

Kev tiv thaiv ntawm SPD degradation

Kev saib xyuas ntawm kev muab hluav taws xob tas mus li

2.3 Kev Tiv Thaiv Arc Fault
YUYE lub tshuab nrhiav arc uas koom ua ke rau hauv MCBs txo cov kev pheej hmoo hluav taws los ntawm xob laim arcing los ntawm 65% piv rau cov qauv txheem.

3. Cov Kev Txwv Tam Sim No ntawm Kev Siv Tshuab

3.1 Cov Teeb Meem Lub Sijhawm Teb
Cov MCBs ib txwm muaj lub sijhawm teb 8-10ms rau cov dej ntws nce siab, uas ua rau lub zog puas tsuaj hla dhau.

3.2 Cov Teeb Meem Kev Sib Koom Tes
Kev sib koom tes tsis zoo ntawm SPD-MCB tseem yog ib qho teeb meem uas tshwm sim ntau, nrog rau 32% ntawm kev ua tsis tiav ntsig txog xob laim yog vim muaj kev tsis sib haum xeeb ntawm cov khoom siv tiv thaiv (Kev Kawm Txog Hluav Taws Xob ntawm YUYE, 2023).
