Cov tsis sib thooj ua cov khoom tseem ceeb hauv hluav taws xob. Lawv txoj haujlwm tseem ceeb yog cais cov khoom siv hluav taws xob thaum kuaj thiab txij nkawm ua haujlwm, ua kom muaj kev tiv thaiv kev nyab xeeb rau kev nyab xeeb rau ob qho khoom siv thiab khoom siv. Ua raws li "tus saib xyuas kev nyab xeeb" ntawm cov fais fab, cov tsis sib haum pom cov ntsiab lus sib tsoo pom tau tias kev saib xyuas kom nyab xeeb rau hauv ib puag ncig txhua yam.
Los ntawm kev ua haujlwm ua haujlwm pom, qhov tsis sib xws siv cov kev ua haujlwm los tsav tsheb hu thiab kaw cov haujlwm. Thaum yuav tsum muaj Circuit Court yog tseev kom muaj, txoj kev sib chwv sib cais los ntawm kev sib chwv nyob hauv chaw nyob ruaj ruaj, tsim kom muaj kev ntseeg siab ntawm kev sib tiv thaiv. Qhov pom tau meej meej tawg sawv cev rau cov tseem ceeb tus nqi ntawm kev tsis sib xws hauv kev siv kev nyab xeeb. Vim yog lawv cov qauv kev coj ua, cov tsis sib xws tsis muaj arc {}} Exches {}}} tua cov haujlwm tom qab lub Circuit Court Breaker tau cuam tshuam nrog Circuit Court.
Nyob rau hauv cov nqe lus ntawm cov nta nta, disponnectors disiversation tsim kev tsim kev teeb tsa. Raws li cov chaw nruab nrog kev teeb tsa, lawv tuaj yeem raug faib rau hauv sab hauv tsev thiab hom sab nraum zoov. Hom Sab Hauv Tsev yog qhov haum rau sab hauv tsev qhov kev hloov kho kom haum rau ib puag ncig kev hloov kho kom pom muaj huab cua ua kom muaj zog xws li nag, daus, thiab dej khov. Xav txog tus naj npawb ntawm insulating ncej, cov qauv muaj xws li ib leeg-}} - kem hom. Ntawm cov no, ib qho - Hom kab yog dav siv nyob rau hauv high {}}} voltage hloov chaw vim nws kom txuag tau qhov chaw installation.
Los ntawm qhov kev xav ntawm cov kev ua haujlwm, cov kev tsis sib txuas tuaj yeem muab faib ua cov haujlwm ntawm kev ua haujlwm thiab hom haujlwm hluav taws xob. Kev ua haujlwm Kev Ua Haujlwm cia siab rau tib neeg kev rau siab, ua kom yooj yim thiab txhim khu kev qha. Lub lag luam hluav taws xob, tsav los ntawm cov motors, ua kom cov chaw taws teeb tswj, yooj yim txhim kho kev ua haujlwm yooj yim thiab kev ua haujlwm. Hais txog kev sib chwv txav, ntau yam tsim muaj nyob suav nrog kab rov tav {}} plug {}}
Tshwj xeeb tshaj yog tsis yog tus hom tshwj xeeb paub raws li load - tawg hloov. Kev tsim kho cov qauv cov qauv, lawv txuas cov khoom siv hluav taws xob yooj yim uas ua rau lawv tsis tuaj yeem tawg tsis ntev- Circuitity durents. Tus qauv no muab cov kev sib luag ntawm cov kab ke nrog Circuit Court thiab Disconnectors hauv cov ntawv thov tshwj xeeb, ua rau pom cov nqi.
Thaum lub sijhawm xaiv cov txheej txheem tiag tiag, kev txiav txim siab ntau yam yog tsim nyog, suav nrog cov kev xav tau ntawm cov kev xav tau, kev ua haujlwm tau zoo, thiab thaj chaw sib luag. Kev xaiv kom tsim nyog tsis tsuas yog ua kom cov kev tsis sib haum xeeb ua rau lawv cov kev tiv thaiv kev nyab xeeb hauv lub zog thiab tseem txhim kho kev ntseeg tau thiab ua haujlwm ntawm tag nrho cov hluav taws xob network.
