Product Details

RWK auto recloser controller is medium voltage overhead line grid monitoring unit, It can be equipped with RCW(ER) type vacuum circuit breaker for achieving automatic monitoring, fault analysis and event records.

Its given to us a safety power grid for cutting line fault and automatic recovery operation and power automation.
RWK series is suitable for up to 35kV outdoor switchgear using, include: vacuum circuit breakers, oil circuit breakers and gas circuit breakers.
RWK 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 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.).

Features

Password Protection – 2 levels.

50Hz/60Hz systems and two phase/three phase wiring method are available, so that the use scope of device is extended.

Protection configuration is complete, and all protection functions can be switched on and off flexibly.

9-way intellectual switching value input.

Large capacity flash memory can record at least 100 times of historical events, and no data will loss even the power is off.

Circuits operating loop can be used both the direct or alternating current, self-adaptation open/close brake function, which can co-work with various of breakers, and the operation is simple and reliable.

The device has complete self-inspection function to in-service monitor the working conditions of various parts of the device, ensuring the reliability of the device.
