Cov khoom muaj cov yam ntxwv ntawm cov qauv yooj yim, hloov tau yooj yim, txhim khu kev qha interlocking, yooj yim installation, thiab lwm yam. Nws tuaj yeem muab cov kev daws teeb meem txaus siab rau ntau lub sijhawm thov thiab cov neeg siv sib txawv. Kev siv cov cuab yeej siv thev naus laus zis thiab cov ntaub ntawv thev naus laus zis, ua ke nrog kev ua tau zoo thiab cov txheej txheem yooj yim thiab hloov tau yooj yim, tuaj yeem ua tau raws li qhov xav tau hloov pauv ntawm kev ua lag luam thiab tsim nyog rau cov kev xav tau ntawm daim phiaj kev txawj ntse.
GHXH-12 ib puag ncig kev tiv thaiv roj rwb thaiv tsev lub nplhaib tseem ceeb series yog tsim rau kev lag luam thiab pej xeem cable nplhaib network thiab kev faib tawm cov phiaj xwm dav hlau. Raws li kev lees paub thiab kev faib hluav taws xob, nws yog qhov tshwj xeeb tshaj yog tsim rau kev faib hluav taws xob hauv nroog thaj chaw, cov chaw me me me me, qhib thiab kaw chaw nres tsheb, cable ceg thawv, lub thawv-hom substations, kev lag luam thiab mining lag luam, khw malls, tshav dav hlau, subways. , cua zog tsim, chaw ntau pob, railways, tunnels thiab lwm qhov chaw siv.
GHXH-12 ib puag ncig tiv thaiv roj-insulated nplhaib lub ntsiab chav tsev ua tau raws li cov qauv hauv lub tebchaws, cov qauv kev lag luam fais fab thiab lwm yam qauv. Nws cov keyboards thiab cov khoom siv hluav taws xob tseem ceeb yog cov khoom siv sib xyaw ua ke, cov khoom siv hluav taws xob ntawm cov theem yog cov khoom siv rwb thaiv tsev, cov kab hluav taws xob sab nraud siv cov hlua khi hlua khi, thiab cov chaw ua haujlwm txuas lub tsheb thauj mus los tau txais kev tiv thaiv insulated busbars. Yog li ntawd, kev nyab xeeb ntawm kev siv tau zoo heev, kev khiav hauj lwm mechanism txais lub caij nplooj ntoos hlav mechanism, thiab lub neej txhua yam yog ntau tshaj 10,000 zaug. Nws cov ntaub ntawv ua haujlwm thiab cov khoom siv raws li txoj cai tuaj yeem raug saib xyuas thiab saib xyuas, thiab nws tuaj yeem tsis saib xyuas. Nws yog ib qho khoom siv hluav taws xob faib nrog ib hom kev ua tau zoo.
Cov chav hauv qab no tuaj yeem raug xaiv hauv lub txee los tsim ib qho kev lag luam thiab siv hluav taws xob siv hluav taws xob:
1. Lub tshuab nqus tsev Circuit Court breaker (630A, 20-25kA)
2. Nqus load hloov tsev (630A, 20-25kA)
Khoom nta
1. Kev tiv thaiv ib puag ncig
Txhua yam khoom siv hauv kev tsim khoom yog cov khoom tsis muaj tshuaj lom thiab tsis muaj mob. N2 los yog huab cua qhuav yog siv los ua ib qho nruab nrab insulating los txo cov pa roj carbon monoxide emissions thiab ua tiav cov hom phiaj tiv thaiv ib puag ncig. Tsis muaj tshuaj lom thiab tsis zoo raug tso tawm thaum siv. Nws tuaj yeem rov ua dua thiab rov siv dua, uas txiav txim siab txog kev tiv thaiv ib puag ncig ntawm kev siv.
2. Ntau yam kev thov
Tsis txhob siv cov pa phem thiab cov pa phem, uas txiav txim siab txog kev nyab xeeb ntawm kev siv ib puag ncig. Txawm nyob hauv qab daus, hauv qhov av, hauv nkoj, thiab hauv ntau qhov chaw sab hauv thiab sab nraud. Sab hauv ntawm lub siab siab chamber tuaj yeem ntim nrog cov cua qhuav lossis nitrogen, uas yog tsim rau cov xwm txheej hnyav xws li: qhov siab siab, muaj zog cua thiab xuab zeb, kub tsis tshua muaj, txias txias, siab tiv thaiv ib puag ncig, qhov chaw ua haujlwm nquag, muaj kev nyab xeeb. Qhov chaw tawg-pov thawj, siab ntsev pos huab, thiab kev nyab xeeb siv nyob rau hauv condensation tej yam kev mob. Tag nrho cov insulated thiab tag nrho nyob rau hauv lub kaw lus, nws yog tsim nyog rau cov cuab yeej siv txuas ntxiv mus ua hauj lwm tom qab noj ib co kev tu thiab ziab kom qhuav tom qab ib tug luv luv lub sij hawm ntawm cov dej inflow.
3. Kev tu-dawb
Ntxiv rau qhov kev khiav hauj lwm mechanism, GHXH-12 ib puag ncig kev tiv thaiv roj-insulated nplhaib lub ntsiab chav tsev series yog nyob rau hauv ib tug tag nrho kaw lub xeev, lub high-voltage hloov ib feem yog kaw tag, thiaj li hais tias kev tu thiab tu yuav tsum zam, thiab tus nqi ntawm cov khoom siv. kev ua haujlwm thiab kev saib xyuas tuaj yeem txo qis.
Lub degree ntawm automation ntawm lub switchgear yog siab heev, thiab lub hauv internet nrhiav kom tau muaj nuj nqi yuav ceeb toom rau cov neeg siv ntawm lub lag luam ntawm cov khoom nyob rau hauv lub sij hawm ntawm lub sij hawm, uas yog ntau conducive rau lub automation ntawm lub network faib, txo cov nqi zog ua hauj lwm, thiab txo cov kev siv ntawm lub automation. cov nqi tsim khoom ntawm cov tuam txhab fais fab.
4. Kev ruaj ntseg siab
Zoo meej interlocking thiab interlocking system, peb-theem kev sib cais nyob deb yog pom meej meej, zam qhov tshwm sim ntawm kev ua haujlwm tsis raug. Daim ntawv thov ntawm SF6 roj raug tshem tawm, thiab cov qauv kev sib cais interphase tau ntxiv dag zog kom tsis txhob muaj kev nthuav dav lossis tawg tawg tshwm sim los ntawm luv luv Circuit Court ntawm theem lossis ntau lub voj voog. Lub tshuab nqus tsev cuam tshuam nrog lub tshuab nqus tsev lub zog ntawm qhov tawg-pov thawj ib puag ncig tiv thaiv roj txee yog saws, thiab cov khoom siv kaw ntom ntom muaj kev tiv thaiv ntxiv rau kev hloov.
5. Yooj yim rau kev khiav lag luam
Lub disconnectorand ntiaj teb hloov nrog tsuas yog ib qho kev khiav hauj lwm kov, thiab tsis tas yuav txheeb xyuas thiab txhawj xeeb txog kev ua yuam kev. Thaum lub Circuit Court breaker khiav, kev khiav hauj lwm kov ntawm lub disconnectorand lub ntiaj teb hloov tsis tuaj yeem ua haujlwm, thiab tsis tas yuav tsum muaj kev cob qhia nyuaj, uas ua rau kev ua haujlwm yooj yim heev, kom tsis txhob ua haujlwm yuam kev.
