Inokulungiswa kwikhabhinethi yokutshintsha okanye ifakwe kwi-handcart.
Ukusebenza okuzinzileyo kunye nokufakwa lula.
Vacuum Indoor Circuit Breaker Product Scope

IiNzuzo ezingundoqo ze-Circuit Breaker
1.Isakhiwo esilula.
2.Adapt isiphazamisi se-vacuum ephezulu esezantsi.
3.I-Adapt optimization kunye nemodyuli yokusebenza kwentwasahlobo.
4.Ifanelekile ngamaxesha asebenza rhoqo.
I-5.Ukugcinwa kwamahhala kunye nobomi benkonzo ende.
6.Ukusebenza okuphezulu okuthembekileyo.
Ipaneli ye-vcb yangaphakathi ye-vacuum breaker panels 11kV vcb panel
Iimeko zokusingqongileyo
Ubushushu be-Ambient: - 40°C~+40°C (ngaphantsi kwama-35°C kwiiyure ezingama-24)
Ukufuma okuhambelanayo: ≤95% (umyinge wemihla ngemihla) okanye ≤90% (umndilili wenyanga)
Ukuphakama: ≤ 1000m
Umatshini wokusebenza luhlobo lwamandla agciniweyo oluhamba simahla kunye nokuvulwa ngokuzimeleyo kunye nokuvala nokuba sithini isenzo somsebenzisi.Indlela yokusebenza isetyenziswa ngokubanzi kuzo zonke ii-VD4-R series circuit-breakers kunye nolawulo lwangaphambili.
I-circuit-breaker inokulawulwa kude xa ifakelwe izixhobo zombane ezinikezelweyo (i-gearmotor, ukukhululwa kokuvula kunye nokuvala).
Indlela yokusebenza, iipali ezintathu kunye ne-sensor zangoku (ukuba zinikezelwe) zifakwe kwisakhelo sesinyithi ngaphandle kwamavili.Ulwakhiwo luxinene ngakumbi, lomelele kwaye linobunzima obulinganiselweyo.
I-VD4-R ichungechunge lwe-circuit-breakers kunye neendlela zokusebenza ezisecaleni zixhobo zoxinzelelo ezitywinwe ubomi obude.(Imigangatho ye-IEC 62271-100)
