Tsis tas li ntawd xwb, cov neeg tsim qauv yuav tsum xav txog seb lub kaw lus puas siv ib qho chaw fais fab lossis ntau qhov chaw, xws li lub zog hluav taws xob thiab cov tshuab hluav taws xob. Cov ntawv thov ua haujlwm tas mus li yuav xav tau derating kom ntseeg tau tias muaj kev ntseeg siab mus sij hawm ntev thiab kev ruaj khov thermal.

2. Soj ntsuam qhov muaj peev xwm tawg thiab qib kev ua txhaum

Cov theem tam sim no luv luv hauv cov txheej txheem kev lag luam tuaj yeem siab heev vim yog cov transformers loj thiab cov tes hauj lwm qis-impedance. Yog li ntawd, lub peev xwm tawg ntawm MCCB yuav tsum txaus kom cuam tshuam qhov siab tshaj plaws ntawm qhov chaw teeb tsa kom muaj kev nyab xeeb.

Ib qho xaiv tau zoo800A MCCByuav tsum muaj peev xwm tawg hluav taws xob txaus thiab kev pabcuam kom phim cov qib kev ua txhaum ntawm lub kaw lus. Kev puas tsuaj uas tsis tau ntsuas txaus tuaj yeem ua rau lub tshuab hluav taws xob tsis ua haujlwm, puas tsuaj loj heev, lossis muaj kev pheej hmoo kev nyab xeeb thaum muaj teeb meem.

3. Xaiv Chav Mus Ncig thiab Kev Tiv Thaiv Uas Tsim Nyog

Kev xaiv chav mus ncig ua si ncaj qha cuam tshuam rau qhov tseeb ntawm kev tiv thaiv thiab kev sib koom tes. Cov chav mus ncig ua si thermal-magnetic feem ntau siv rau cov ntawv thov tus qauv, thaum cov chav mus ncig ua si hluav taws xob muab qhov tseeb dua thiab kev teeb tsa kev tiv thaiv hloov kho tau.

Cov khoom siv hluav taws xob tso cai rau kev kho kom zoo ntawm qhov overload, short-circuit, thiab lub sijhawm ncua sijhawm, uas pab ua tiav kev sib koom tes xaiv nrog cov khoom siv upstream thiab downstream. Hauv qee lub tshuab kev lag luam, cov haujlwm tiv thaiv ntxiv xws li kev kuaj pom qhov txhaum hauv av kuj tseem yuav xav tau.

4. Xav txog qhov chaw teeb tsa thiab cov yam ntxwv ntawm kev siv tshuab

Cov chaw ua haujlwm hauv kev lag luam tuaj yeem ua rau muaj kev kub ntxhov, nrog rau qhov kub thiab txias siab, plua plav, kev co, thiab av noo. Cov xwm txheej no cuam tshuam rau kev ua haujlwm ntawm lub tshuab hluav taws xob thiab lub neej ua haujlwm. Kev xaiv lub thawv kaw, qhov cua, thiab qhov chaw kom zoo yog qhov tseem ceeb kom tiv thaiv kev kub dhau thiab xyuas kom muaj kev nyab xeeb ua haujlwm.

Tej yam uas yuav tsum xav txog thaum siv lub tshuab hluav taws xob suav nrog kev teeb tsa, kev sib txuas ntawm cov xov hlau lossis cov busbar, thiab kev nkag tau yooj yim rau kev tshuaj xyuas thiab kev txij nkawm. Kev xaiv tus qauv breaker uas ruaj khov yuav ua rau lub zog siv tau ntev dua thiab txo lub sijhawm tsis ua haujlwm ntawm lub cuab yeej.

5. Xyuas kom meej tias Cov Qauv Ua Raws Cai thiab Kev Siv Tau Zoo

Kev ua raws li cov qauv thoob ntiaj teb xws li IEC ua kom ntseeg tau tias MCCB ua tau raws li kev nyab xeeb, kev ua tau zoo, thiab kev kuaj xyuas. Cov ntawv thov hauv kev lag luam feem ntau xav tau kev ntseeg siab siab, kev ua tau zoo ruaj khov, thiab lub neej ua haujlwm ntev.

Kev xaiv lub breaker los ntawm lub chaw tsim khoom uas muab cov ntaub ntawv qhia txog kev siv tshuab, cov ntaub ntawv kuaj, thiab kev txhawb nqa tom qab muag pab ua kom ntseeg tau tias qhov kev daws teeb meem xaiv tseem tsim nyog thoob plaws lub neej ua haujlwm ntawm lub system.
