Research on the Application of Safe Power Supply Technology for Underground Mechanical and Electrical Equipment in Coal Mines
In order to solve the problems of poor safety performance,inadequate monitoring of abnormal power supply,and easy occurrence of power supply system failures in the power supply mode of underground mechanical and electrical equipment in coal mines,this paper studies and explores the safe power supply technology of underground power supply equipment,proposes a remote monitoring system for underground power supply safety,builds a ground monitoring subsystem and an underground monitoring subsystem,introduces the hardware system structure composition and software control system.The proposed safety monitoring system for underground electromechanical equipment has been applied in a coal mine,and it has been demonstrated that real-time collection and monitoring of parameters such as current,power,and voltage of electrical equipment can be achieved,and the upper computer can clearly display the power supply situation of underground equipment.After 6 months of use,the system runs smoothly and the data transmission speed is fast.The anomalies collected on site will be presented in a visual curve with historical records,making it easy to call up data at any time in the later stage.The abnormal response time is only 1.82 s,effectively ensuring the safety and reliability of the underground power supply system and achieving satisfactory application results.
