Product Description
1. Product introduction
Autotron DJKQ-2000C series centralized monitor is the main component of DC power supply set of high frequency switch for electric power. Through telephone network, optical fiber, standard serial interface or network, it can form an intelligent monitoring system of team DC system with the computer of monitoring and dispatching center in the background. The centralized monitor monitors the charging machine, storage battery, DC bus, insulation monitoring device, AC/DC distribution device, etc. of DC system in real time by means of distributed control, and completes the communication with the upper computer to realize the four remote functions of DC system, such as "remote communication", "telemetry", "remote control" and "remote adjustment". Widely applicable to large and medium power plants, 500kV and above substation and other places, but also suitable for 220kV and below substation, user stations, small power plants and other places.
