The invention discloses a mine power
network monitoring and guaranteeing
system. The mine power
network monitoring and guaranteeing
system comprises a comprehensive control center, an optic
fiber Ethernet exchanger, a KFJ81 underground measurement and control
station, a detection and alarm unit, an
electric energy information collection unit, an intelligent protection unit and a power source unit, wherein the detection and alarm unit, the
electric energy information collection unit and the intelligent protection unit are communicated with the KFJ81 underground measurement and control
station through an RS-485 communication mode, and mainly perform state detection, fault early warning, information collection and
remote control on a mine power network, the KFJ81 underground measurement and control
station exchanges information with the comprehensive control center through two methods of using the optic
fiber Ethernet exchanger and a ZigBee
wireless network, and the power source unit is composed of a common power source and an emergency power source, and guarantees that the mine power
network monitoring and guaranteeing
system can run smoothly under various situations. The mine power network monitoring and guaranteeing system achieves the purposes of monitoring and controlling the mine power network from all directions, improves running efficiency and safety level of the mine power network, and provides reliable guarantees for safe production of a mine.
