Lo mzekelo udibanisa indlela yokusebenza kunye ne-breaker circuit, ihlelwe kakuhle, ikhangeleka intle kwaye ihlangene.2.Le modeli inokuqhutywa rhoqo, ikwazi ukwaphula kunye nokuvala ngokukhawuleza amaxesha amaninzi.3.Iintlobo ezimbini zofakelo (ezilungisiweyo okanye ezisusiweyo) zihlangabezana neemfuno zee-switchgears ezahlukeneyo.(VS1)-12 yi-HV yangaphakathi ye-vacuum breaker yesekethe esebenza njengeyunithi yokukhusela kunye nolawulo lwezixhobo zegridi yamandla kunye nezixhobo zombane zombane kwinkqubo yamandla ombane olinganisiweyo ukusuka kwi-7.2KV ukuya kwi-12KV.Ihlangabezana neemfuno ze-GB/T1984-2014 (i-AC HV i-circuit breaker) kunye ne-JB355-1996 (3.6KV-40.5KV yangaphakathi ye-AC HV i-vacuum breaker circuit).Ingasetyenziselwa kwii-switchgears ze-KYN28 (GZS1), i-XGN kunye ne-GG-1A.
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)
