DESCRIPTION

Product use

KJ1296 mine power supply monitoring system is developed to adapt to 10KV and below substation power safety monitoring system in coal mine; Based on the characteristics of coal mine power supply and distribution system and the mature technology of ground power distribution management system, it adopts the latest technology of ground power system automation, embedded system technology, distributed network technology, etc., and integrates my company's more than 20 years of research experience in coal mine power supply and distribution system, and independently develops coal mine professional power monitoring system. It is an integrated power station automation system that integrates the functions of measurement, protection, control and communication. It realizes real-time power data acquisition, data recording, fault diagnosis, fault warning, fault recording and so on for underground high and low voltage power supply equipment. Thus, the ground dispatching center can realize the five remote functions of telemetry, remote communication, remote adjustment, remote viewing and remote control of the underground high and low voltage power supply equipment, which significantly improves the stability and reliability of the mine power supply system, effectively reduces the occurrence of unplanned power failure accidents in the mine, and can generate a variety of records and statistical reports.

Main feature

With excellent operating platform, based on Linux operating system software architecture, anti-virus, maintenance-free, fully ensure the safety and reliability of power supply monitoring;

The system has good real-time performance, timely and accurate feedback of monitoring and control information; The system has good expansibility, adopts tree structure and strong adaptability, which can meet the requirements of multi-branch power supply network in coal mine.

With Ethernet and RS485 communication interface, easy to use, high transmission rate, large amount of information;

The system capacity is large, with a maximum of 256 sub-stations, each sub-station can monitor 16 high-low voltage switches;

Electronic listing function: with maintenance operation safety guarantee function, maintenance operation electronic identification plate can be set on the monitoring screen of the system during maintenance operation. After the identification plate is set, unauthorized personnel can not cancel the identification plate, nor can remote control operation be carried out, thus eliminating the safety hazard of remote incorrect power transmission during maintenance operation and fully guaranteeing the safety of maintenance operators;

Full coverage of satellite time calibration, accurate accident playback function adopts Beidou and GPS dual-mode satellite time calibration, network timing server to monitor the system's monitoring server, monitoring operation station, high and low voltage protection device clock calibration, so that the whole system's monitoring and protection device clock consistent, fully ensure the accuracy and reliability of accident analysis; At the same time, it can accurately reflect the action sequence of the protection switch to realize the accident replay;

The system has the function of substation environment monitoring to realize the environment monitoring when the substation is unattended, and to alarm the abnormal situation to improve the substation unattended management.

Protection setting remote modification, online optimization function: equipment protection setting remote modification on the ground, unified management, while the system through online monitoring of the power load, according to the power load big data analysis results, online optimization of the switch protection setting, fully ensure the rationality and effectiveness of the switch protection setting, making the mine power supply more secure;

The underground substation has a one-key power recovery function, and the power recovery logic program is set by the user.

Telemetry function: The system can display and query the real-time data, historical data, event records and other parameter values of the switch, three-phase voltage, current, zero sequence voltage, zero sequence current, apparent power, frequency, insulation resistance, power factor, equipment cavity temperature and so on;

Remote control function: high and low voltage switch on and off control operation, protection signal recovery operation, start wave recording operation and hanging repair plate, provide and realize the high and low voltage switch remote control of two operation control methods; The circuit can be divided and closed on the protector and the system host. Local control and remote control can be selected.

Remote communication function: real-time online monitoring of switch change, hand car position, grounding brake state, wind power gas input state, control output state, fault alarm state semaphore;

Telemetry function: display the current overload, short circuit, leakage delay and other setting values of each high and low voltage switch on the ground; Incoming side voltage value; Current value on the load side; The opening and closing state of the switch; Telemetry and collection of electric energy, quantity, peak and valley value, etc.

Remote adjustment function: On the system monitoring host, the protection setting, time-sharing period setting, maximum demand cycle setting, settlement point setting, communication setting and other operations can be carried out remotely online.

Remote viewing function: equipped with camera, it can monitor the substation remotely;

Mobile APP mobile monitoring function: real-time grasp of downhole switch operation, the system applies advanced "Internet +" technology to achieve mobile power supply monitoring, through the special mobile APP can be mastered at any time power supply safety situation, solve the power supply safety risks, improve the power supply safety management level;

Main technical parameters of mine flameproof and intrinsic safety type power supply monitoring sub-station
