Switchgear yog cov cuab yeej tseem ceeb hauv lub tshuab hluav taws xob kom paub txog lub zog faib hluav taws xob, kev sib kis, thiab kev tiv thaiv. Nws txoj hauv kev ua haujlwm yog nyob ib puag ncig kev hloov hluav taws xob tswj, kev sib cais tsis raug, thiab kev saib xyuas kev nyab xeeb, tsim ib qho tseem ceeb lav rau kev ua haujlwm ruaj khov ntawm daim phiaj hluav taws xob.
Los ntawm kev pom kev ua haujlwm yooj yim, switchgear siv cov cuab yeej tseem ceeb hauv lub hauv paus xws li cov khoom siv hluav taws xob, kev sib txuas ntawm cov keyboards, cov keyboards thauj khoom, thiab cov keyboards hauv av kom ua tiav kev kaw thiab qhib kev ua haujlwm. Circuit Court breakers muaj arc-tuaj yeem tua hluav taws, txuas lossis tshem tawm cov khoom thauj tam sim no thaum lub sijhawm ua haujlwm ib txwm muaj, thiab nrawm nrawm los txiav tawm cov khoom siv hluav taws xob tsis raug thiab tiv thaiv kom tsis txhob muaj kev huam yuaj tshwm sim hauv qhov xwm txheej luv luv, overloads, lossis lwm yam txhaum. Disconnecting keyboards feem ntau yog siv los tsim kom pom tseeb hluav taws xob tawg thaum lub sij hawm tu cov cuab yeej los xyuas kom meej tus kheej kev nyab xeeb; lawv tsis muaj arc- tua muaj peev xwm thiab tsuas yog ua tau tom qab lub Circuit Court breaker tau qhib. Load keyboards tuaj yeem txuas lossis txiav tam sim no nyob rau hauv ib qho kev muaj peev xwm thiab feem ntau siv nrog fuses kom ua tiav kev tiv thaiv yooj yim. Grounding keyboards yog siv los grounding Circuit Court thaum lub sij hawm tu, tshem tawm cov seem seem thiab tiv thaiv kev sib tsoo hluav taws xob.
Ntxiv nrog rau lub hauv paus Circuit Court, lub switchgear yog nruab nrog cov khoom xws li tam sim no transformers, voltage transformers, thiab surge arresters. Tam sim no transformers hloov siab voltage thiab tam sim no loj rau hauv qis voltage thiab me me tam sim no siv los ntsuas cov cuab yeej thiab cov cuab yeej tiv thaiv, ua kom muaj tiag - lub sijhawm tau txais thiab cov chaw taws teeb saib xyuas cov hluav taws xob tsis zoo. Surge arresters txwv overvoltages, tiv thaiv cov khoom siv sab hauv los ntawm xob laim ntaus lossis ua haujlwm overvoltages.
Secondary Circuit Court yog lub hauv paus hub rau kev txawj ntse tswj thiab kev tiv thaiv nyob rau hauv lub switchgear. Relay tiv thaiv cov cuab yeej tshuaj xyuas cov teeb liab los ntawm sab nraud ntawm cov tam sim no transformers los txiav txim seb puas muaj qhov txhaum lossis qhov tsis zoo nyob hauv qhov system thiab tsav lub Circuit Court breaker ua haujlwm raws li kev xav tau preset. Lub Circuit Court tswj tau txais kev qhib thiab kaw cov lus txib los ntawm cov chaw hauv zos lossis thaj chaw deb, ua kom muaj kev tswj xyuas meej ntawm cov txheej txheem khiav haujlwm. Lub teeb liab hluav taws xob xa cov khoom siv raws li txoj cai, tswb, thiab cov ntaub ntawv tsis raug mus rau kev saib xyuas, txhawb cov lus teb raws sij hawm los ntawm cov neeg ua haujlwm tu.
Nyob rau hauv cov nqe lus ntawm kev khiav hauj lwm, lub switchgear txhawb lub zos phau ntawv, hluav taws xob, thiab tej thaj chaw deb automated tswj, ua tau raws li kev khiav hauj lwm thiab kev tswj cov kev xav tau ntawm txawv scenarios. Cov cuab yeej sib cuam tshuam tau sib koom ua ke thoob plaws hauv ob qho tib si thawj thiab theem nrab kev ua haujlwm los tiv thaiv kev nyab xeeb los ntawm kev ua haujlwm tsis raug, xws li tiv thaiv kev ua haujlwm ntawm kev sib txuas ntawm cov keyboards hauv qab thauj khoom lossis kev sib tsoo nkag mus rau hauv cov khoom siv hluav taws xob.
Feem ntau, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub switchgear suav nrog cov cuab yeej tseem ceeb uas ua haujlwm hloov thiab kev tiv thaiv, thaum lub kaw lus thib ob tswj xyuas, tswj, thiab teeb liab sib cuam tshuam, ua kom muaj kev nyab xeeb los ntawm kev sib cuam tshuam. Qhov kev sib koom ua ke ntawm cov organic no ua rau lub tshuab hloov pauv kom ntseeg tau faib lub zog thiab muab kev tiv thaiv zoo hauv qhov nyuaj thiab puas tau - hloov pauv hluav taws xob ib puag ncig.
