KR-2000Introduction to Series Distributed Protection Devices

●It is mainly suitable for various power supply systems with voltage levels of 35kV and below. The distributed installation protection device CPU adopts a 32-bit DSP main body, fully localized LCD display, detailed and intuitive information, and easy operation and debugging.

●The protection device records protection action events with time information and maintains power-off status. The device integrates protection, measurement, remote signaling, remote control and other functions. The communication adopts standard RS-485, which is economical and convenient for networking and can directly communicate with monitoring or protection management machines.

●This series mainly includes KR-2110 high-voltage motor protection, KR-2210 high-voltage line protection, KR-2230 high-voltage busbar protection, KR-2310 high-voltage capacitor protection, and KR-2410 high-voltage transformer protection.
