Deskripsyon
Ang RWK-55 overhead line protection switch intelligent controller mao ang medium voltage overhead line grid monitoring unit, mahimong pagbutangan sa RCW(RVB) type vacuum circuit breaker aron makamit ang automatic monitoring, fault analysis ug event records.
Naghatag kini og safety power grid para sa cutting line fault ug automatic recovery operation ug power automation.
Ang serye sa RWK-55 katugasan sa pila ka 35kV outdoor switchgear gamiton, kasinabi na: vacuum circuit breakers, oil circuit breakers ug gas circuit breakers. Ang RWK-55 intelligent controller nagpuyo sa line protection, control, measurement ug monitoring sa voltage ug current signals integrated automation ug control devices sa labas.
Ang RWK mao ang automatic management unit para sa single way/multi ways/ring network/two power sourcing, gihatagan sa tanang voltage ug current signals ug tanang functions. Ang RWK-55 column switch intelligent controller nagsuporta: Wireless (GSM/GPRS/CDMA), Ethernet mode, WIFI, optical fiber, power line carrier, RS232/485, RJ45 ug uban pang mga anyo sa communication, ug mahimo nga mag-access sa uban pang station premises equipment (kasama ang TTU, FTU, DTU, etc.).

Q: Ano ang gibuhat sa line protection switch controller?
A: Kini gamiton sa proteksyon sa seguridad sa line. Kon ang line adunay overload, short circuit o uban pang abnormal conditions, ang line protection switch controller mahimong maayo nga matubag kini nga problema, ug maka-cut off sa circuit, aron maprotektahan ang line gikan sa dako nga current, aron maputli ang sunog ug uban pang dangerous situations. Q: Asa kini natubag sa anomalya sa line?
A: Adunay sophisticated current detection device sa sulod. Kon ang current sa line mogawas sa set nga safe value, sama sa overload o short circuit, ang detection device mahimong masentrihan ang pagbag-o sa current ug maisulat ang controller action.
Q: Handa ba ang line protection switch controller?
A: Sa general, kon qualified product, handa kini. Ang electronic components mahimong maayo nga screened, ug ang housing adunay maayo nga protection ug makapag-adapt sa uban pang environmental conditions, pero regular nga i-check ug maintain aron siguro nga makapagtumong sa maayo.
