Recloser
Rockwill has designed a new type recloser controller. Comparing with previous controllers, this one is smaller, multi-interface, and more applicable.
Its given to us a safety power grid for cutting line fault and automatic recovery operation and power automation. It is suitable for up to 38kV outdoor switchgear using, include: vacuum circuit breakers, oil circuit breakers and gas circuit breakers. This intelligent controller is gathering with line protection, control, measurement and monitoring of voltage and current signals integrated automation and control devices outdoors.
RWK is a automatic management unit for single way/multi ways/ring network/two power sourcing, provided with all voltage and current signals and all functions. RWK-351 column switch intelligent controller supports: Wireless (GSM/GPRS/CDMA), Ethernet mode, WIFI, optical fiber, power line carrier, RS232/485, RJ45 and other forms of communication, and can access other station premises equipment (such as TTU, FTU, DTU, etc.).
