Intelligent fault detection and analysis system of coal mine power based on TD-SCDMA

Abstract

In view of problem that fault of underground power supply equipment leads great hidden danger to coal mine safety production, an intelligent fault detection and analysis system of coal mine power based on TD-SCDMA technology was proposed. The system collects each segment bus voltage, each branch current, power, state of breaker and fault information in real-time through detection and collection system of power supply, then transmits running state, running parameters, fault information of coal mine power supply and distribution system to intelligent power fault analysis system through TD-SCDMA/industrial Ethernet support system, so as to complete information processing and analysis and fault diagnosis and processing of coal mine power supply and distribution system. The application result shows that the system improves reliability of power supply, and provides guarantee for coal mine safety production.
