Thaum lub sijhawm ua haujlwm, qis-voltage switchgear assemblies tej zaum yuav ntsib teeb meem xws li overloading lossis luv circuits. Thaum muaj qhov tsis zoo tshwm sim, cov khoom siv hluav taws xob yuav tsum tau txiav ua ntej txhawm rau tshuaj xyuas cov khoom siv hluav taws xob thiab cov khoom siv. Nyob rau hauv qhov kev tshwm sim ntawm ib tug Circuit Court breaker mus txawv tebchaws, nws yog tsim nyog los soj ntsuam seb qhov ua rau lies nyob rau hauv ntau load los yog luv luv Circuit Court. Yog tias kuaj pom tias muaj cua sov ntawm busbar, cov kev sib txuas yuav tsum raug kuaj xyuas kom lawv muaj kev nyab xeeb. Rau cov kev ua yuam kev nyuaj, nws raug nquahu kom hu rau cov neeg ua haujlwm rau kev pab.
Tsav los ntawm kev txhim kho thev naus laus zis, qis -voltage switchgear cov rooj sib txoos tau hloov mus rau kev txawj ntse thiab kev siv hluav taws xob ntau dua. Cov qauv khoom siv tshiab tau nce ntxiv nrog cov yam ntxwv xws li kev saib xyuas tej thaj chaw deb thiab kev tau txais cov ntaub ntawv, yog li ua rau cov neeg siv tau txais kev tswj hwm lub zog ntau dua. Tsis tas li ntawd, kev siv eco-cov ntaub ntawv tus phooj ywg thiab lub zog- txuag cov khoom tau nthuav dav zuj zus, ua rau txo qis kev siv hluav taws xob thaum lub sijhawm ua haujlwm ntawm cov khoom siv.
