GENERAL

DK series distribution automation feeder terminal (hereinafter referred to as "automation terminal") is a feeder terminal unit of the overhead line of a distribution system of 40.5kV and below. It cooperates with the column circuit breaker or load switch to realize automatic detection of line status, fault analysis and judgment record, drive switch and protect line equipment safety, It has the functions of cutting off the line for permanent fault and instantaneous recovery of the short-term fault of the line.

The automation terminal is a comprehensive automatic outdoor measurement and control equipment that integrates line protection, control, voltage, and current signal measurement and monitoring. It has all functions of processing all voltage, and current signals, and remote operation of switches of a single overhead line.

The automation terminal supports wireless (GSM / GPRS / CDMA), Ethernet, optical fiber, and RS232 / RS485 communication, and can also be connected to other master station systems.

The automation terminal complies with technical standards such as the DL / T 721-2013 remote terminal of the distribution network automation system.
