Nruab nrab Voltage Switchgear
YVG-12 Khoom Ring Ring Network Txee

YVG-12 series khoom rwb thaiv tsev nplhaib network switchgear yog ib tug tag nrho insulated, tag nrho kaw, thiab txij nkawm dawb khoom rwb thaiv tsev lub tshuab nqus tsev switchgear.
Lub nplhaib network txee muaj cov yam ntxwv ntawm cov qauv yooj yim, hloov tau yooj yim, txhim khu kev qha interlocking, thiab yooj yim installation, thiab yog haum rau 50Hz, 12 kV fais fab system. Nws yog dav siv nyob rau hauv industrial thiab civil cable nplhaib tes hauj lwm thiab tis network davhlau ya nyob twg tej yaam num, raws li ib tug txhais tau tias ntawm kev txais thiab faib hluav taws xob, tshwj xeeb tshaj yog haum rau lub nroog thaj chaw faib, industrial thiab mining tuam txhab uas muag siv nyob rau hauv tshav dav hlau, subways, cua zog tsim, tunnels, thiab lwm qhov chaw.
Haum rau siv nyob rau hauv cov cheeb tsam uas hnyav ib puag ncig xws li qhov siab siab, siab kub, av noo, muaj kuab paug hnyav, thiab lwm yam.
Qauv: IEC62271-1-200 IEC62071-2000-2003

Kev xaiv

Muab faib los ntawm kev ua haujlwm hauv lub cev: lub txee nkag, lub txee rau sab nraud, lub tsheb thauj khoom, lub txee ntsuas, PT txee, nqa txee, thiab lwm yam, sawv cev los ntawm cov txheej txheem xov tooj. Raws li hom kev hloov pauv tseem ceeb, nws yog
muab faib ua: load hloov txee, load hloov fuse ua ke hluav taws xob txee, Circuit Court breaker txee, thiab cais hloov txee, thiab lwm yam, sawv cev los ntawm F (fuse ua ke cov khoom siv hluav taws xob), V (circuit breaker), C (load hloov), thiab lwm yam.

Cov xwm txheej ua haujlwm

1. Ambient Kub: Tsis ntau tshaj +45 ℃, Tsis pub tsawg tshaj -45 ℃. Qhov nruab nrab kub tsis tshaj +35 ℃ hauv 24 teev. 2. Qhov siab: Tsis pub tshaj 3000m.

Feature

1. YVG- 12 switchgear feem ntau muaj peb chav ua haujlwm, uas yog V unit (circuit breaker unit), C unit (load switch unit), F unit (combined hluav taws xob unit), thaum lub kaw lus yuav tsum tau ntau chav nyob rau configured, yuav ua tau arbitrarily nthuav dav ntawm sab laug thiab sab xis, thiab tuaj yeem teem caij arbitrarily raws li kev tsim qauv sib txawv kom ua tiav qhov sib txawv
configuration xav tau.
2. Txhua chav tsev tau muab faib ua peb ntu: chav ntsuas, kev ua haujlwm mechanism thiab thawj lub voj voog. Cov
Chav ntsuas ntsuas tuaj yeem nruab nrog microcomputer tiv thaiv (tus tswj ntse) thiab lwm yam ntsuas. Kev khiav hauj lwm mechanism yog lub caij nplooj ntoos hlav ua haujlwm tshwj xeeb, uas tuaj yeem nruab nrog kev ua haujlwm hluav taws xob ntxiv
mechanism; lub hauv paus Circuit Court txais APG tsis siv neeg gel technology, thiab lub tsheb npav bar, cais hloov thiab arc
extinguishing chamber raug kaw tag nrho hauv epoxy resin, thiab muaj cov pob qij txha tshwj xeeb txuas nrog lub tsheb npav.
3. YVG- 12 khoom rwb thaiv tsev switchgear muaj qhov zoo ntawm cov qauv compact, tag nrho cov rwb thaiv tsev, lub neej ntev, txij nkawm-dawb, me me chaw ua hauj lwm, kev nyab xeeb thiab kev cia siab, thiab tsis cuam tshuam los ntawm kev ua hauj lwm ib puag ncig. Nws yog dav siv hauv kev lag luam thiab pej xeem lub nplhaib network thiab cov khoom siv hluav taws xob.
