KR-1000PIntroduction to Series Protection Measurement and Control Devices

●This series of protective devices is suitable for three types of load power supply and distribution systems with various voltage levels of 10kV and below, and can be used as protective devices for transformers, motors, lines, and capacitors in the system.

●The same software platform is used in the development and design process of this series of devices, so it can protect all different types of protected objects. It has three-stage overcurrent protection, locked rotor protection, motor start protection, zero sequence current protection, two-stage negative sequence overcurrent protection (where section II can be set with inverse time limit), overvoltage protection, low voltage protection, zero sequence low voltage protection, low cycle protection, remote signaling and remote control functions, transmission test functions, action recording and signal memory functions that will not be lost in case of power failure. In addition, the device provides two sets of central signal contacts, which are respectively used as protection actions and protection alarms.

●The development and design of the product based on the same platform have improved the high interchangeability of individual devices and ensured convenience during maintenance, greatly enhancing the cost-effectiveness of the product.

●This device adopts high-performance 32-bit DSP as the main body, and the protection device can work safely in an environment of -10 ℃ to+50 ℃ for a long time. It has time information and protection action event recording, and maintains power-off status. The device integrates protection, measurement, remote signaling, and remote control, and uses RS-485 bus for communication. It is economical and convenient to network, and can directly communicate with monitoring or protection management machines. It has a fully functional circuit breaker operation circuit, compatible with AC and DC operations, and is suitable for controlling various types of circuit breakers. The device adopts a standard structure with a height of 4U and a back plug board, fully ensuring manufacturing quality in terms of process.
