CKPM502 boundary switch control device is a distribution network automation terminal mainly developed for the application of ring main unit and central cabinet system. It is very suitable for ring main unit system with harsh operating environment and limited installation location. It has interphase current quick-break, over-current, zero-sequence over-current protection, reclosing, over-voltage, low-voltage protection and non-electricity protection alarm, tripping functions, and also has monitoring functions such as multi-electricity measurement, remote control, and remote signaling.

Features

Quick start; the whole machine adopts extremely low power consumption design technology to ensure that the protection function can start reliably and quickly under any conditions; high-precision components and processes ensure the accuracy, reliability and long service life of the device; 

Simple structure; simple and compact device structure, convenient and flexible installation, suitable for the compact installation conditions of the ring network cabinet; using full Chinese LCD display interface, multi-layer menu display, very friendly man-machine interface; 

Flexible configuration; flexible and complete protection configuration, various protection functions can be switched on and off freely through the control word; the device provides RS-232 and RS-485 communication bus interfaces, and provides users with an open communication protocol to facilitate the realization of SCADA functions; 

Comprehensive measurement and control; with complete measurement and control functions, which can measure electrical parameters such as voltage and current; provide special remote control relays to achieve remote control functions; with 8 switch input circuits; 

Historical records; the large-capacity non-volatile memory of the device ensures that 200 historical event records are recorded, with detailed record content, and data will not be lost when power is turned off; 

Dynamic and static self-inspection; the device has a complete dynamic and static self-inspection function, online monitoring of the working conditions of each part of the device, to ensure the working reliability of the device;
