Cov haujlwm tseem ceeb ntawm switchgear

Switchgear (tseem hu ua lub pob hluav taws xob los ua kom tiav lub zog hluav taws xob) yog cov khoom siv hluav taws xob raws li cov hluav taws xob sib txuas. Switchgear hais txog tias cov chaw tsim khoom sib sau cov khoom siv hluav taws xob loj thiab tsis tshua muaj hluav taws xob (suav nrog cov khoom siv hluav taws xob tiv thaiv, cov cuab yeej hluav taws xob tiv thaiv, thiab ntsuas cov cuab yeej hluav taws xob), cov tsheb npav, cov khoom siv tam sim no, cov kab hluav taws xob, thiab lwm yam, nyob rau hauv lub kaw lossis qhib hlau txee raws li cov tseev kom muaj ntawm daim duab hluav taws xob txuas ntawm thawj daim duab hluav taws xob. Hauv lub cev, ua khoom siv rau kev txais thiab faib hluav taws xob hauv lub zog hluav taws xob.

Lub tshuab hloov hluav taws xob ntau yog hais txog lub luag haujlwm ntawm kev qhib, kev tswj lossis kev tiv thaiv nyob rau hauv cov hluav taws xob system tiam, kis tau tus mob, xa tawm, hloov dua siab tshiab thiab siv hluav taws xob. Lub txee rau lub cev yog qhov dav, qhov chaw sab hauv yog loj, kev tshem tawm yog tsim nyog thiab nyab xeeb, nws muaj cov yam ntxwv ntawm kev teeb tsa yooj yim thiab tu, thiab kev ua haujlwm zoo. Lub ntsiab hluav taws xob sib xyaw ua tiav, uas tuaj yeem ua tau raws li qhov xav tau ntawm ntau lub zog siv hluav taws xob thiab xa cov tshuab. Lub siab hloov hluav taws xob yog qhov qhib hom. Cov qauv yooj yim yog welded nrog lub kaum sab xis steel. Pem hauv ntej vaj huam sib luag yog nias los ntawm nyias steel phaj. Tsis muaj daim phiaj thaiv sab nrauv. Sab hauv ntawm lub txee raug sib cais los ntawm nyias steel phaj. Sab qaum sab ntawm lub txee tiv thaiv yog Circuit Court breaker chamber thiab hauv qab ntu yog cais. Lub chav hloov pauv muaj qhov ua haujlwm ntawm kev thaiv, uas muaj kev nyab xeeb thiab txhim khu kev qha siv.

Lub switchgear muaj tsib lub zog los tiv thaiv kev ua tsis tiav:

1. Tiv thaiv qhov cuam tshuam ntawm disconnect nrog load.

2. Tiv thaiv kom txhob yuam kev nkag mus rau hauv lub sijhawm raug tsub nqi.

3. Tiv thaiv qhov tsis muaj xwm txheej qhib thiab kaw ntawm Circuit Court breaker.

4. Tiv thaiv cov hlau hauv av los ntawm khuam nrog hluav taws xob.

5. Tiv thaiv kaw nrog rau xaim hlau.

Lub switchgear muaj cov haujlwm ntawm overhead hlau nkag thiab tawm, cable nkag thiab tawm, tsheb npav sib txuas thiab lwm yam. Nws yog qhov tsim nyog rau ntau qhov chaw xws li cov chaw tsim hluav taws xob, chaw hla chaw, petrochemicals, nws yog xim hlau hlau dov, lub teeb pom kev lag luam thiab cov ntaub, cov chaw ua haujlwm thiab cov tuam txhab tsuas, thaj chaw nyob, thiab cov tsev siab. Cov khoom siv hluav taws xob ntau hluav taws xob muaj qee yam ua haujlwm thiab kev siv tshuab lossis hluav taws xob sib cuam tshuam. Kev xyaum tau ua pov thawj tias: tsis muaj" tsib kev tiv thaiv" kev ua haujlwm lossis" tsib kev tiv thaiv kev ua tsis tiav" yog qhov tseem ceeb ntawm kev siv hluav taws xob
